When the water pressure is large, what is the valve that automatically discharges water?

It's called a pressure relief valve.

There are different pressure value specifications, and if the pressure exceeds this value, the water will be automatically discharged.

The pressure relief valve, also known as the safety valve, can be automatically opened and closed according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, the pressure relief will be automatically opened to ensure that the medium pressure in the equipment and pipeline is below the set pressure, protect the equipment and pipeline, and prevent accidents.

There are two main types of pressure relief valve structures: spring type and lever type. Spring-loaded refers to the force of the spring force between the sealing of the disc and the seat.

The lever type relies on the force of the lever and the hammer. With the need for large volumes, there is another pulse type pressure relief valve, also known as pilot operated pressure relief valve, which consists of a main pressure relief valve and an auxiliary valve. When the pressure of the medium in the pipeline exceeds the specified pressure value, the auxiliary valve is opened first, and the medium enters the main pressure relief valve along the conduit, and the main pressure relief valve is opened to reduce the pressure of the increased medium.

The purpose of installing a pressure reducing valve in tap water is to reduce the water pressure in the high-pressure water supply network to the water pressure requirements in the water pipe network of Yubi users, so as to ensure safe and reliable water use. The function of the pressure reducing valve is that when the water pressure in the water supply pipe network exceeds the water pressure requirements in the user's unit water pipe network, it can automatically control the water pressure in the water supply pipe network and reduce the water pressure to the water pressure requirements in the user's unit water pipe network to ensure water safety. However, due to the design principle of the pressure reducing valve, when the outlet of the pressure reducing valve reaches the set drainage pressure, the outlet of the pressure reducing valve will still have a certain flow rate, so that the water volume will also have a certain flow rate, resulting in the outflow of water that is larger than the chain damage after the tap water is installed with the pressure reducing valve.

Summary. Dear, the tap water is still very large when the pressure reducing valve is installed, which indicates that the pressure of the tap water supply is too high. When the tap water supply pressure is too high, the water supply pressure of the tap water itself will cause the pressure relief valve to continuously relieve pressure and drip.

In this case, you can try to close the valve opening on the water supply line or replace a pressure relief valve directly. Or you may close the valve on the water supply line when the water heater is not in use, and then open the valve when the hot water is to be used.

Dear, the tap water is equipped with a pressure reducing valve, and the source of the water source is still very large, which indicates that the pressure of the tap water supply is too high. When the tap water supply pressure is too high, the water supply pressure of the tap water itself will cause the pressure relief valve to continuously relieve pressure and drip. In this case, you can try to close the valve opening on the tap water supply tubing or directly replace a pressure relief valve.

Or close the valve on the water supply line when the water heater is not in use, and then open the valve when the hot water is to be used.

Is there any other way to decompress.

There is no one. Pro, the decompression method is as follows: 1) The most conventional hand is to connect a pressure reducing valve on the pipeline, and the spring on the pressure reducing valve can be adjusted, so the size of the pressure can be adjusted. 2) Adjusting the flow rate with a valve can also reduce the pressure, for example, the valve is very small, and the flow rate of tap water is small, and the pressure will naturally be lowered.

At present, basically all families use tap water, because tap water is more convenient to use, and it is also more hygienic, so it is loved by many families, but some families will have certain troubles because of excessive pressure when using tap water. Today, I will explain to you the adjustment method of the pressure reducing valve.

1. How to adjust the tap water pressure reducing valve.

The first thing you need to do is to open the top cover of the pressure reducing valve and release the pressure relief valve counterclockwise with a hex wrench; Secondly, remove the plug on the pressure gauge of the pressure reducing valve; Then install the pressure reducing valve on the tap water pipeline, and after confirming the installation, directly close the ball valve of the pressure reducing valve; Finally, use a hex wrench to rotate the pressure reducing valve clockwise, and pay attention to the data on the pressure gauge, but when the pressure gauge data increases to a certain extent, you can stop the rotation and cover the top cover.

2. Precautions for the installation of tap water pressure reducing valves.

1. When installing, the tap water pressure reducing valve should be installed vertically on the tap water pipeline.

2. The arrow on the tap water pressure reducing valve must be consistent with the arrow on the pipeline.

3. The position of the installation of the pressure reduction method must be greater than 4 meters from the valve outlet.

3. What are the characteristics of tap water pressure reducing valves?

1. The internal structure of the pressure reducing valve is very simple, without any jamming, so it is more convenient to use.

2. It is very convenient to clean, so there is no need to install a filter.

3. It is suitable for use in various pipelines, because it can meet the requirements of many kinds of pipeline pressure reduction.

Fourth, which material is better to buy a tap water pressure reducing valve?

It is better to choose the tap water pressure reducing valve made of ductile iron, because this material will not rust no matter how many years of use, and it is rare to block the bridge banquet situation, now the market is the most important material of this material tap water pressure reducing valve brand is very many, when buying, we must look for the 3C logo, but also to compare the price of several sellers, so as to buy an economical and affordable tap water pressure reducing valve.
