Model principle and manufacturer introduction of back pressure valve

Back pressure valve is still very common in our life. Its pressure can be adjusted. Its main function is to control the flow of water, steam, air and various corrosive media, mud, liquid metal and radioactive media. It also has a hydraulic control system to cut off and intercept. In addition, the chemical properties of the back pressure valve are stable, but many friends are not very familiar with the back pressure valve. Then Bian Xiao will tell you about the knowledge and hope of the back pressure valve.

Back pressure valve model

Back pressure valve model: flange back pressure valve, BYF flange back pressure valve, BYF- 16P flange back pressure valve, BYF- 16R flange back pressure valve, BYF flange back pressure valve specification: DN6-DN 150.

Working principle of back pressure valve

The fluid enters from the inlet of the back pressure valve and is blocked by the diaphragm, so the fluid exerts upward pressure on the diaphragm. When the pressure is large enough, the spring is compressed, and the fluid lifts the diaphragm to form a channel and flows out from the outlet of the back pressure valve; If the fluid pressure is not enough, pressure retention will be formed, so that the inlet pressure will rise until it reaches the rated pressure, and the diaphragm will be pushed up to form a channel. The rated pressure of the back pressure valve can be adjusted, generally by adjusting the ejector pin at the upper end of the spring, so as to adjust the length of the spring.

Back pressure valve is the largest fluid output device at present, and its working principle is also realized by the elasticity of built-in spring. When the pressure of the system exceeds the set pressure, the diaphragm of the back pressure valve can block the pipeline under the elastic force of the spring, and the set pressure will rise, which is very helpful for realizing fluid transportation. Moreover, the function of the back pressure valve is to ensure the stability of the outlet flow of the pump and protect the pipeline, elbow and joint from the impact of pressure fluctuation. You can imagine how important the back pressure valve is.
