What principles should be complied with in the layout of indoor water supply pipelines in building e

1. Meet the best hydraulic conditions.

1. The layout of water supply pipelines should be short and straight.

2. In order to make full use of the water pressure in the outdoor water supply network, the water supply inlet pipe is declared to be located at the place where the water consumption is the largest or where the water supply is not allowed to be interrupted.

3. The indoor water supply main pipe should be close to the place where the water consumption is the largest or where the water supply is not allowed to be interrupted.

Second, to meet the maintenance and aesthetic requirements.

1. Pipelines should be laid in a straight line along walls, beams and columns as far as possible.

2. For buildings with high aesthetic requirements, water supply pipelines can be concealed in pipe grooves, tube wells, pipe trenches and ceilings.

3. In order to facilitate maintenance, the tube well should be equipped with an access door on each floor. For pipes concealed in the ceiling or pipe groove, there should be a access door at the valve.

4. There should be enough space for the indoor pipeline installation location to facilitate the disassembly and replacement of accessories.

5. The water supply inlet pipe should have a slope of not less than 0 003, and the slope outdoor water supply pipe network or slope valve well.

Water meter wells for the discharge of stored water during maintenance.

3. Ensure the safety of production and use.

1. The location of the water supply pipeline shall not hinder the production operation, transportation and the use of buildings.

2. The water supply pipeline shall not be arranged on the top of the water that can cause combustion, damage or damage to raw materials, products and equipment, and should try to avoid passing on the production equipment.

3. Water supply pipes shall not pass through shop windows and civil buildings.

closets and wood decorations, etc.

4. For workshops and buildings that are not allowed to cut off water, two water supply inlet pipes should be set up, and the water supply should be connected into a ring or through the branch in the room.

The water supply pipeline follows the principle of having pressure to let there be no pressure, and small pipe to making large pipe. When piping, it is horizontal and vertical, and it is mainly arranged in two ways: open installation and concealed installation.

The layout and laying of the internal drainage pipes of the building should meet the requirements of smooth drainage, good hydraulic conditions, convenient maintenance, complete production and use, long service life, prevention of water quality and environmental pollution, economic and beautiful appearance.

Things to pay attention to in the internal drainage pipes:

Pipe installation: Internal dirt and debris must be removed before installation to prevent blockage.

2.Pipe frame production and installation: in strict accordance with the requirements of the construction drawings blanking, welding, after anti-rust treatment, installed on the load-bearing structure, the position should be correct, the burial is smooth and firm, and the pipeline contact is close.

3.Water supply and drainage pipeline installation: the water supply horizontal pipe should have a slope, and the slope drainage device: the diameter and minimum slope of the drainage pipe should be constructed in strict accordance with the design requirements.

4.Pipeline connection: The water supply pipeline is made of galvanized steel pipe and connected by thread connection; The indoor drainage pipe and the outlet pipe are made of drainage cast iron pipe and asbestos cement interface.

5.Anti-corrosion: surface-mounted galvanized steel pipe.

What principles should be complied with in the construction equipment engineering indoor water supply equipment?

Kiss! Hello, happy to answer your <>

What principles should generally be complied with for the indoor water supply equipment of the pro-building equipment engineering are as follows: make full use of the external network water pressure to supply water directly, and when it cannot be satisfied, the upper layers of pressurized water supply are used. When the water quality of two or more water uses is close, the common water supply system should be used as far as possible.

The production water supply system should give priority to the setting of a circulating water supply system or the reuse of the water supply system, and the remaining pressure should be used. The water pressure borne by the system's pipes, accessories and accessories shall not be greater than the allowable working pressure specified in the product standard. Hope mine can help you <>

Item A, according to Article 1 of the "Design Standards for Building Water Supply and Drainage" (GB 50015-2019), when the living balcony is equipped with domestic drainage equipment and floor drain, there is no need to set up a balcony rainwater drainage floor drain. Therefore, there is no longer a separate rainwater riser and a floor drain to remove rainwater on the ground, and the washing machine drainage floor drain can be used as a ground drainage floor drain, which can reduce the number of drainage risers and floor drains on the balcony.

Item B, Article 1 stipulates that the drainage of medical sterilization and disinfection equipment shall be indirectly drained, and the hall shall be chaotic rather than the floor drainage of the sterile operating room of the hospital.

Item c, Article 1 stipulates that the drainage pipe shall not be arranged above the operation, cooking and preparation of staple and non-staple foods in canteens and catering kitchens. When it cannot be avoided due to conditions, protective measures should be taken. Protective measures can be used to remedy the situation.

Item d, Article 1 stipulates that toilets, washrooms, and other rooms that need to be drained from the ground frequently shall be equipped with floor drains to act as companions.

1) The principle of the layout of the water supply network is as follows: in the case of ensuring the uninterrupted water supply, the shorter the pipeline is laid, the better it is; It is necessary to consider the possibility of relocation of each section of the pipe network during the construction period; The main water supply pipeline adopts a ring arrangement, and branch lines can be set up at isolated points; make the best use of existing or pre-built permanent pipelines; The diameter of the pipe is determined by calculation.
