It is composed of inlet pipe, water supply pipe, water supply accessories, water distribution equipment, pressurization and storage equipment, and metering instruments. The functions of each section are as follows:

1. Inlet pipe: also known as inlet pipe, is a pipe that leads from the connection point of the outdoor water supply pipe network to the building.

2. Water supply pipeline: used for transporting and distributing water, that is, the pipeline of water supply sent by the introduction pipe to each water point in the building, including horizontal main pipes, water supply risers and branch pipes.

3. Water supply accessories: all kinds of valves and equipment in the pipeline system to adjust the water volume and water pressure, control the direction of water flow, improve water quality, and shut down the water flow to facilitate the maintenance of pipelines, instruments and equipment.

4. Water distribution equipment: a device on the terminal water point of the pipe network of the water supply system for living, production and fire fighting.

5. Pressurization and water storage equipment: including pressurization equipment and water storage equipment.

6. Metering equipment: water meters, including household water meters and total water meters.

Feed water classification. According to the nature of the system, the classification of water supply system can be divided into:

1. According to the type of water source, it is divided into: surface water (rivers, lakes, reservoirs, oceans, etc.) and groundwater (shallow groundwater, deep groundwater, spring water, etc.) water supply system;

2. According to the water supply mode, it is divided into: artesian system (gravity water supply), pump water supply system (pressure water supply) and mixed water supply system;

3. According to the purpose of use, it is divided into: domestic water, production water and fire water supply system;

Fourth, according to the service object is divided into: urban water supply and industrial water supply system, in industrial water supply, it is divided into circulation system and reuse system.

Significance. A reliable urban water supply system is the basic condition for the survival and development of cities. Water supply projects have become an important infrastructure for cities and industrial and mining enterprises, and must ensure that sufficient water supply, qualified water quality, and sufficient water pressure can be used for domestic use, production water and other water, not only to meet the needs of the near future, but also to take into account future development.

With the increasing scale and the complexity of the pipe network structure, the optimal scheduling and management of the water supply system needs to be put on the agenda urgently.

The indoor water supply system is mainly composed of the following departments:

1) Inlet pipe: The outdoor water supply pipe network passes through the outer wall (or foundation) of the building and enters the indoor pipe, which is generally calculated at a distance of 2m from the outer wall.

2) Indoor pipeline: mainly composed of buried pipes, risers, horizontal trunk pipes, branch pipes, etc.

3) Water distribution point: faucets, fire hydrants, water equipment, sprinkler heads, etc. for various types of sanitary ware.

4) Ancillary equipment: pressurized and stabilized equipment, high-level water tanks and water storage tanks (boxes) set up according to the nature, height and fire protection level of the building.

5) Metering and control part: Metering water meters and sub-household water meters are installed at the entrance of buildings or residential building units. The pipeline is equipped with control valves, check valves, alarm valves, water flow indicators, etc.

The water supply project is generally composed of four parts: the towerless water supply structure of the water supply source, the water pipeline, the water supply treatment plant and the water distribution pipe network, which respectively assume the role of collecting and transporting raw water, improving the quality of raw water and transporting qualified water to users. Under normal topographical conditions, the system also includes the necessary water storage and pumping facilities. According to the requirements of water source, topography and water saving and energy saving, water supply projects can be divided into the following systems.

1) Gravity water supply system: water from the water supply equipment structure to the water point, or from the water supply treatment plant to the user point, is transported by gravity, does not have to be pumped, this is the most energy-saving and safe system. (2) Multi-source water supply system:

It is suitable for water supply in large cities by several surface water sources, several underground water sources, or a combination of surface water sources and underground water sources. (3) Qualitative water supply system: according to the different requirements of water objects for water quality, it can be divided into several system water supply systems that are completely treated, partially treated or even do not need to be treated, and it is suitable for water supply systems that supply water to residents and industries respectively or several kinds of industrial water quality with large differences.

4) Partial pressure water supply system: according to the different pressure requirements of the water use area, it is divided into high pressure area and low pressure area water supply, and this system can be used in areas with great difference in terrain elevation. (5) Circulating water supply system:

It is a water supply system that conserves water resources, such as a circulating cooling water system, by resupplying the water used at the point of use after proper treatment or replenishment of new water. (6) Sequential water supply system: the water used by the water consumption units with high water quality requirements is supplied to the units with low water quality requirements, which is also an effective industrial water system that saves water resources.

7) Reclaimed water supply system: the water treated by the water treatment plant is supplied to some industrial, agricultural, urban cleaning, greening and other water.

A water supply system is a facility or pipeline that collects and treats water from a water source in order to deliver purified water** to public and private homes, commercial buildings, factories, etc. A water supply system usually consists of the following components:

First, water. Water sources refer to natural water sources or water collected from underground or surface water sources, such as reservoirs, rivers, etc.

Second, the water intake project. Water intake projects include pipelines, pumping stations and pressurization works that collect water from water sources to water supply facilities.

Third, treatment facilities. A treatment facility is a facility that purifies and treats raw water collected from a water source, including processes such as coagulation, flocculation, sedimentation, filtration, disinfection, softening, and desalination.

In general, the main task of the water supply system is to ensure that we have access to a sufficient amount of clean and safe drinking water to provide the necessary water resources for our life and economic activities.

There are six classifications, as follows:

1. Direct water supply mode.

Application: The water volume and water pressure of the outdoor pipe network can meet the indoor water requirements at any time of the day.

2. Separate water tank water supply mode.

Application: Fill the water tank with water when the water pressure in the outdoor water supply network is sufficient (generally at night); When the pressure of the outdoor pipe network is insufficient (usually during the day), the water supply is supplied by the water tank.

3. Combined water supply mode of water pump and water tank.

Application: When the pressure in the outdoor water supply network is lower than or periodically lower than the water pressure required by the internal water supply network of the building, and the internal water consumption of the building is very uneven.

4. Pneumatic tank water supply mode.

Application: The water pressure of the outdoor pipe network is often insufficient, and it is not suitable for buildings with high-level water tanks.

5. Set up the water supply mode of the water pump.

Advantages: If the pressure of the outdoor pipe network often cannot meet the indoor water supply requirements, and the indoor water consumption is large and uniform, a separate water pump can be set up for water supply. The water output is uniform, the pump works stably, and the energy consumption of electric banquet is relatively small.

6. Zonal water supply mode.

In a multi-storey building, when the pressure of the outdoor water supply pipe network can only meet the water supply requirements of several floors below the building, in order to make full use of the water pressure of the outdoor pipe network, the water supply system of the building can be divided into two water supply areas, upper and lower. It is especially economical for buildings with laundry rooms, bathhouses, large restaurants, canteens, etc., which have large water consumption on the lower floors of the building. <>

Feed pumps, feed pipes and valves.

Feedwater Pump: A water pump that increases the feedwater pressure.

Water supply pipeline: It is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., through plastic extruder extrusion molding and injection molding machine injection molding, through cooling, curing, shaping, inspection, packaging and other processes to complete the production of pipes and pipe fittings.

Valve: It is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveyed medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc.

Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems range from the simplest shut-off valves to the most complex valves used in automated control systems.

The building water supply system is a cold water supply system that introduces the water in the municipal water supply pipe network (or self-provided water source) into the building and transports it to the water points such as indoor water distribution faucets, production units and fire-fighting equipment, and meets the requirements of various water equipment for water quality, quantity and water pressure.

1. Classification of building water supply system.

Building water supply systems can be divided into three categories according to their use:

1 Domestic water supply system.

The water supply system for drinking, cooking, washing, washing, bathing and other daily water supply systems in residences, public buildings and industrial enterprise buildings must strictly comply with the "Sanitary Standards for Drinking Water" stipulated by the state.

2 Production of water supply systems.

Due to the different production processes, there are many kinds of production water supply systems, which are mainly used for the water required in the production process of various products, the cooling of production equipment, the washing of raw materials and products, and boiler water. The requirements for water quality, quantity, water pressure and safety of production water vary greatly with different process requirements.

3 Fire water supply system.

Water supply systems for firefighting in residential buildings, public buildings and production workshops. Fire water does not have high requirements for water quality, but it must be in accordance with the requirements of the building fire protection design code to ensure sufficient water volume and maintain a certain water pressure.

The above three types of basic water supply systems can be set up independently, or according to the different requirements of various users for water quality, water quantity, water pressure, etc., combined with the actual situation of the outdoor water supply system, through technical and economic comparison or taking into account social, economic, technical, environmental and other factors to be comprehensively considered, set up into a common system with different combinations. Such as living and production shared water supply system; shared water supply system for living and fire fighting; production and fire protection shared water supply system; Living, production, fire and fire sharing water supply system.

In industrial enterprises, the water supply system is relatively complex, and due to the different water pressure, water quality, water temperature, etc. required in the production process, it is often divided into several separate water supply systems. In order to save water, production water can be divided into recycling, reuse, and a combination of recycling and reuse.

Second, the composition of the building water supply system.

1 Water source. Refers to a municipal water supply network or a self-supplied water source. The water source of civil buildings should generally be the first choice of urban tap water, when the water supply of self-provided water sources is used, the water quality must meet the "Sanitary Standards for Drinking Water" well reported to the local health department for testing and approval before it can be used.

2 Drop tubes.

For a single building, the inlet pipe is the connecting pipe section between the outdoor water supply pipe network and the indoor water supply pipe network, also known as the inlet pipe.

Building water supply systems.

Building water supply system: It is a water supply system that introduces water from the urban (regional) water supply pipe network or self-provided water source into the room, sends it to the water equipment for living, production and fire fighting through the indoor water distribution pipe network, and meets the requirements of each water point for water quantity, water pressure and water quality.

1) Classification and composition of building water supply systems.

1.Building water supply systems can be divided into three categories according to their use:

1) Domestic water supply system: the system that supplies people's domestic water, the water volume and water pressure should meet the requirements, and the water quality must meet the relevant national drinking water hygiene standards.

2) Production water supply system: supply water and cooling, product and raw material washing required in the manufacturing process of various products, and its water quality, water pressure and water volume vary according to different product types and production processes.

3) Fire water supply system: It is generally a special water supply system, which does not have high requirements for water quality, but must meet the requirements of the building design fire code for water volume and water pressure.

2.Composition of a building's water supply system.

The internal water supply system of the building is composed of inlet pipes, water meters, water supply pipelines, water distribution devices and water equipment, pressurization and storage equipment, water supply accessories, etc.

2) Water supply scheme.

The water supply scheme is determined based on factors such as the height of the building, the amount of water consumed, the layout of the water distribution points, and the pressure and volume of the outdoor water supply network.

Commonly used water supply schemes are: direct water supply, indirect water supply, and zonal water supply.

1.Water from the direct water supply outdoor network directly enters the indoor pipe network. When the pressure and volume of the outdoor water supply network can meet the indoor water requirements, this simple and economical water supply method should be adopted.

This type of water supply sometimes needs to be adjusted by setting up a water tank. When using the water tank, attention should be paid to the pollution prevention and control of the water in the water tank.

2.If the water of the outdoor pipe network of indirect water supply enters the indoor pipe network after passing through the water tank or booster equipment, the pressure and flow rate of the water are basically not affected by the water supply pipe network.

Indirect water supply is further divided into the following ways:

1) Set up the water supply method of the water tank.

2) Set up the water supply method of the water pump.

3) Set up the water supply method of water pump - water tank.

4) Set up the water supply mode of pneumatic water supply equipment.

3.The high-rise building with partition water supply has many layers and a large height, and must be divided into several areas vertically, otherwise it will cause water leakage in the pipeline and accessories, large water flow in the low-rise pipeline, noise and other adverse effects, and in serious cases, it will damage the valve and burst the pipeline.

Note: Zonal water supply is indirect water supply.

3) Water supply pipes, water distribution devices, accessories and water meters.

The water supply piping system inside the building is made up of pipes, fittings and various accessories, as well as water meters. Quiwang Property Management is the exam channel – divider ---
