Micro pressure back pressure valve

Micro pressure back pressure valveIntroduction:

Back pressure valve can stabilize pipeline pressure, provide a stable back pressure for the system, and improve material feeding accuracy; It can also be used as a nitrogen sealing valve for storage tanks or as a pressure relief valve for storage tanks!

Working Principle:

The rated pressure of the back pressure valve can be adjusted, usually by adjusting the top rod of the spring to adjust the length of the spring. The fluid enters from the back pressure valve inlet and is blocked by the diaphragm, causing the fluid to exert upward pressure on the diaphragm. When the pressure is high enough, the spring is compressed, and the fluid pushes up the diaphragm to form a channel, which flows out from the outlet of the back pressure valve; If the fluid pressure is not sufficient, it will form a build-up pressure, causing the inlet pressure to rise until it reaches the rated pressure, and lifting the diaphragm to form a passage.
