What valves do water companies use? What effect do they have? What is the compensating effect?

Butterfly valves, gate valves, valves generally do not have a compensation role, he is mainly to cut off the water flow, regulate the role of the water flow, to compensate should be selected compensator, generally there are steel telescopic devices, cast iron telescopic devices, ductile iron telescopic devices, these telescopic devices and valves are installed together, one can play a role in absorbing the compensation of pipeline expansion, and the other can play a very good role in valve maintenance and disassembly.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Many soft-sealed butterfly valves play the role of shut-off, and regulate the flow of water.

Water company valves:

The water supply system is a water supply system in which the water plant transports the treated water to various water points through the municipal water transmission and distribution pipe network, and this process sometimes requires secondary pressurization. The pipeline is a pressure conveying pipeline, and the most used are gate valves, globe valves, ball valves, butterfly valves, check valves, soft connections, etc., and the coating and internal treatment of each valve must meet the requirements of drinking water sanitation license.

The tap water valve generally refers to the civil valve, which is commonly used in ordinary households, such as gate valves, ball valves, and triangle valves, which are generally made of iron or copper. Because steel valves have the advantages of not being easy to rust and strong corrosion resistance, copper valves have gradually replaced iron valves. The surface of the triangle valve is basically electrogalvanized, which is not only used to control the flow of pipeline media, but also to play a decorative role.

Triangle valves are generally used for water supply with connecting pipes and inlet hoses, and there are also connecting pipes and inlet hoses for water heater water supply. Gate valves are basically used for the connection of pipes and water meters. Ball valves are used to connect pipes and water heaters.

Because the opening and closing of the ball valve is more convenient than the gate valve, the current connection between the pipeline and the water meter is mostly the ball valve.

The valves of water companies are generally butterfly valves and globe valves.

Gate valves, check valves, pressure reducing valves.

Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. You can refer to it, the quality service of these manufacturers is good. These are also the top ten brand enterprises that are currently recognized in China.

One of the two valves for water inlet is self-adjustable, and the other is dedicated to the water company, and the check valve is to avoid the water meter reversing due to the backwater.

The water meter is in front of the bai valve.

The DU is set up to facilitate the maintenance of the water company, and the professional term DAO is called the valve in front of the meter. The front valve in the meter is turned on, and your home will have tap water. If you owe money, the water company will send someone to turn off the valve in front of your meter.

Professional tools are required to open and close the valve in front of the meter, and ordinary people can't get it.

The valve behind the water meter is set for ease of use, and the function of the check valve installed in the water meter is mainly to ensure the accuracy of the measurement of the water meter and safeguard the interests of users. Because if there is no check valve installed, once the municipal pipe network stops water, the water potential behind the meter will flow back, and the metering accuracy of the water meter for the return water cannot be guaranteed, and some will even affect the normal use accuracy of the water meter.

The exhaust valve is generally installed on the pipeline where the medium is water, and a part of the air will be released in the process of water flowing in the pipeline, and when the air in the pipeline accumulates excessively, it will produce air resistance, affect the flow, and may even cause the pipeline to rupture, and the function of the exhaust valve is to discharge the air in the pipeline.

Automatic exhaust valve.

How it works. When the system is filled with water, the gas in the water continues to escape and accumulate to the highest place due to temperature and pressure changes, and when the gas pressure is greater than the system pressure, the float will fall and drive the valve stem to move downward, the valve port will be opened, and the gas will be continuously discharged. When the gas pressure is lower than the system pressure, the float rises and drives the valve stem to move upward, and the valve port is closed. This is how the automatic exhaust valve works in a continuous cycle!

Automatic exhaust valve.

During the operation of HVAC system and HVAC system, many adverse effects of gases such as hydrogen and oxygen released when water is heated will damage the system and reduce the thermal effect, and these gases will have many adverse consequences if they are not discharged in time. Such as: corrosion due to oxidation; the formation of air pockets in the radiator; The hot water circulation is not smooth and unbalanced, so that some radiators are not hot locally; noise when the pipeline is running with gas; Vortex phenomenon of circulating pumps.

Therefore, the exhaust gas in the system must be discharged in time, which shows the important role of using automatic exhaust valves.

It will not be possible to stop the water for no reason. Generally, if there is a dispute. The metaphor is that in arrears, the water company will collect the fee first. If not, they have the right to stop the water.

You don't say anything, I don't believe that they stopped the water for no reason.

The water is sent to the user's home through the pipeline, and there is generally a valve on the pipeline in order to control a section of the pipeline, which is generally a dendritic pipe network to the user's home, that is, the user is like a small tree fork, and each small tree fork will have a valve to control it alone, and this small tree fork is to the user's branch pipe. If there is only one user of the branch pipe, then stop this valve will stop the user's home, the general control valve will be set together with the water meter, depending on the situation you described, it should be a tap water household and a meter user, from the total inlet of your home to find downstairs, you will find your own single control valve, but generally useless, because the water company will find a way you can not recover the water cut-off, such as: 1 The valve is encrypted, and the special key can be opened 2

Directly disconnect the pipe, remove the water meter, and the water will naturally not come through if the pipe is disconnected.

The answer depends on what the most advanced water meter is electronic, click in the computer system, let which meter stop which meter stops, followed by the water meter with a special shape valve handle, you have to use a special handle to open the valve, the simplest and most commonly used is to remove the water meter directly.

There is a special valve in front of the user's water meter, which is triangular.

It depends on what kind of water meter it is.

The most advanced is electronic, click in the computer system, let which meter stop which meter stops, followed by the water meter with a special shape valve handle, you have to use a special handle to open the valve, the simplest and most commonly used is to remove the water meter directly.

In the following situations, the water company will close the valve and stop the user's water:

1.arrears of water bills for longer than the delivery time;

2.maliciously non-payment of water bills;

3.stealing water;

4.construction of change piping;

5.overall water reform, etc.

Tap water is sent to the user's home through the pipeline, and there is generally a valve on the pipeline in order to control a section of the pipeline, which is generally a dendritic pipe network to the user's home, that is, the user is like a small branch, and each small fork will have a valve to control it separately, and this small fork is to the user's branch pipe. If there is only one user of the branch pipe, then stop this valve will stop the user's home, the general control valve will be set together with the water meter, depending on the situation you described, it should be a tap water household and a meter user, from the total inlet of your home to find downstairs, you will find your own single control valve, but generally useless, because the water company will find a way you can not recover the water cut-off, such as: 1 The valve is encrypted, and the special key can be opened 2

Directly disconnect the pipe, remove the water meter, and the water will naturally not come through if the pipe is disconnected.

Extended Information: Is a Water Company a Public Institution?

Water companies are public institutions.

Public institutions are generally institutions set up by the state with a certain public welfare nature, but they do not belong to the first organization, and their staff are different from civil servants. In accordance with the spirit of the reform of the classification of state public institutions, public institutions are no longer divided into institutions with full appropriation and public institutions with differential appropriation, but into public welfare first-class institutions and second-class public welfare institutions.

The distinctive characteristics of public institutions end with words such as center, club, office, station, team, hospital, society, Taiwan, palace, hall, etc., such as accounting center, health supervision office, judicial office, banking and insurance regulatory commission, quality supervision station, safety production supervision brigade, etc. Public institutions are divided into public institutions and general public institutions. Public institutions participating in public affairs refer to the use of personnel in the establishment of public institutions, which are managed with reference to the Civil Servants Law.

The business scope of the water supply company includes tap water production, **, to meet the water needs of urban residents and units for living and production, and to ensure that the water pressure and water quality of the effluent plant meet the national "Drinking Water Sanitation Standards". Responsible for the installation of water supply equipment for urban and residential users, and ensure the quality of water supply equipment and installation projects. Municipal public works design, construction, installation and engineering construction management services, manufacturing, sales and maintenance of water equipment and materials, water technology development, technology transfer, water quality testing, experimental analysis, consulting, services, foreign investment (shall not be engaged in illegal fundraising, absorption of public funds and other financial activities), operation management and consulting, import and export of goods, import and export of technology.

I wonder if the landlord is asking about the municipal pipe network of the water company or the production water plant of the water company? Generally speaking, there are too many types of valves, each with its own use in the tap water system, and all kinds of valves are needed. The number should be regarded as the largest in the water supply network, and the types of shut-off valves and gate valves are the most.

The water supply company uses the water solenoid valve produced by the manufacturer of the Keweina solenoid valve.

The working principle of the locking valve: The valve magnetic lock is a kind of valve magnetic lock, which is composed of a bonnet, a valve stem, a bonnet cap and a handle. There is a connecting device on the bonnet cap and the valve stem, and the bonnet is provided with a steel pin groove, and a magnet is placed at the bottom, the magnet is sleeved in the spring, and the steel pin is placed on the spring.

The bonnet is provided with a groove, the handle is ring-shaped, the outside of the bonnet cap and the handle are provided with at least a pair of grooves and the corresponding bumps, and the grooves and the bumps are consistent, and the opposite surfaces of the built-in magnet on the handle and the magnet in the steel pin groove are different magnetic poles.

The valve magnetic lock has simple structure, reasonable design, convenient use, and effectively prevents abnormal opening and closing operation of the valve.

Unlocking: This process is used to control the opening, adjustment, and closing of the valve, as well as to keep the locked cap open. Put the key cover on the lock cap, so that the small red dot on the key is aligned with the small dot on the lock, gently press down a few times, the lock cap will pop up, that is, it is in the open state, and pull out the lock cap with your hand.

If it's not stealing water, find a water company, if it's stealing water, the water company will look for you, if it's selling advertisements for stolen products, the public security bureau will look for you.

If the valve of the public water supply pipeline is turned off for no reason in the house on the first floor, affecting the normal life of others, and the violation of the law and infringement, you can complain to the neighborhood committee, village committee, property management and other units, and request them to resolve the dispute over the cessation, or you can file an infringement lawsuit.

According to the General Principles of the Civil Law:

Article 83: The adjacent parties to the immovable property shall, in accordance with the spirit of conducive to production, convenience of life, solidarity and mutual assistance, fairness and reasonableness, correctly handle the adjacent relationship in terms of water interception, drainage, passage, ventilation, lighting, etc. Where obstructions or losses are caused to neighboring parties, the infringement shall be stopped, the obstruction removed, and the losses compensated.

This is causal: because the water comes from the tap water pipe, but it is feces and smelly water that goes down, so you have to think about people's feelings worse, so it makes sense to turn off the water, everyone should raise funds in time to dredge, and you can't win a lawsuit, I am a lawyer, I have fought such a lawsuit, in addition: the valve on the first floor should be the original development of the real estate have, in order to maintain the convenience, so no one has the right to dismantle the valve, there is only one way:

Even the residents who use the pipes should jointly raise funds to dredge or jointly raise funds to modify or thicken the sewer pipes, use them carefully, and debris (especially hair) should be fished out and thrown into the trash can, and the time to block the sewer again should be as long as possible.
