Pneumatic diaphragm valve is also something we often use, but, we really understand it? Can you solve some of the problems that arise? Next will give you a simple talk about the main reasons for pneumatic diaphragm valve water leakage, I hope to help you.
Pneumatic diaphragm valve in the opening and closing process to bear greater pressure, sudden action to change the state of water flow, pneumatic diaphragm valve gradually opened from the closed state to form a gap, the shear force generated by the water flow on the gate, causing cutting on the edge of the gate, multiple action may make the rubber ring off or break, and the gate gap, the valve is not strict phenomenon.
1. Quality problems of the gate and gate body fall off or the anticorrosive layer of the gate body or gate body is thin, resulting in rust of the gate body and gate body. The thickness can be up to 30-50 mm, which causes the gate body to be immovable or the sealing rubber strip on the gate body to be damaged due to rust blocks falling slag, resulting in lax valve. The sealing rubber ring has quality defects, installation is not fast or thickness is too thin, so that the sealing rubber ring falls off in the process of moving brake;
2, Long-term immobility and pneumatic diaphragm valve maintenance is not in place, resulting in difficult operation of pneumatic diaphragm valve, pneumatic diaphragm valve long-term inactivity or no maintenance, resulting in serious rust in the gate head or gate plate, rust and scale fall off resulting in pneumatic diaphragm valve is not strict, inconvenient operation.
