Mr. LI
August 25, 2026
Valve broken: the cause of valve broken is the check valve before and after the medium pressure in close to balance and mutual "see-saw" state, valve often with the valve seat beat, some brittle materials (such as cast iron, brass, etc.) made of the valve is broken. The way to prevent is to use the valve for the toughness of the material of the check valve.
Medium backflow: the reasons for the backflow of the medium are ① damage to the sealing surface; ② clamping impurities. Repair the sealing surface and cleaning impurities, you can prevent backflow.
