Domestic valve common to several major problems

With the ongoing urbanization, a towering buildings rise up, in order to rational use of water, especially the bottom of the safe use of water, it is inevitable to make extensive use of pressure relief valve, However, some real estate developers in order to save costs, the majority Using a cheap domestic pressure reducing valve, the quality of customs clearance, which led to many problems, small pressure relief valve, daily life has brought a great impact, from the past few years, especially in the past two years with the end user Communication, domestic pressure reducing valve main problems are as follows: First: domestic pressure reducing valve reduction pressure is not reduced static pressure, as long as most of the people in the line have heard, as the name suggests, that is, when you use water pressure relief valve function Decompression, when the water valve pressure before the valve is the same, with direct drinking water, many people choose to install a home, but sometimes the bottom of the owners will be surprised to find themselves equipped with a pressure reducing valve straight Drinking fountains or pipe burst, it is because the domestic pressure reducing valve is not static sake, if someone at home is fine, if no one is estimated to have flooded home. The same when you find your home just opened the tap when the water is very urgent, but the water becomes smaller immediately, it is certainly caused by the decompression valve is not static pressure. Imported pressure reducing valve does not exist such a problem, even at the end of unmanned water outlet pressure to ensure that the set value; Second: Domestic pressure relief valve outlet pressure instability, with the inlet pressure fluctuations and fluctuations, I believe this issue a lot People have come across, really good pressure reducing valve, the outlet pressure fluctuations on the outlet pressure has almost no effect, and installed a domestic pressure reducing valve will find that when no one at night when the water pressure at home when the water peak during the day When the pressure at home is small, the faucet is suddenly big and small, especially when the shower, shower water will be cool for a while, bathing is not enjoyment, is completely suffer, in winter it is easy to make a cold, at the same time , Pressure instability on the lot of water heaters at home have a great impact. Imported pressure relief valve stability, the outlet pressure from the inlet pressure, the outlet can always maintain the water pressure as a fixed value; Three: Domestic pressure reducing valve noise, often property companies have called over the water pipe at night The noise is very big but can not find out the reason, the plot owner has great opinion, I generally let him quiet time to go to the pressure reducing valve where to listen, in the first place is its problem, some domestic pressure reducing valve due to the valve Body internal design is not reasonable, when the water flow through the spool will have a lot of noise, especially in some buildings do not exhaust the water supply and drainage works, gas and water flow from the valve spool will It is absolutely unbearable to give a rather sharp voice to the working-class children and elderly children who are under pressure from the city. This will seriously affect the quality of sleep. Imported relief valve machining accuracy is higher, the design is more reasonable, the noise can be generally controlled below 30 decibels; In addition, the domestic valve, such as the use of cast iron material is easy to rust, resistance is too large to affect the flow of other issues, in short, China's manufacturing industry still has a lot of room for development. Whether it is design or processing precision, the quality and performance of domestic pressure relief valves are expected to catch up with European countries such as Italy and Germany at an early date.
