The Pneumatic Diaphragm Valve Diaphragm Is A Sensitive Elastic Element Used On The Diaphragm Valve Core.

Sanitary Diaphragm Valve is a sensitive elastic element used on the diaphragm valve core. The pneumatic diaphragm valve diaphragm is used in valves, regulating valves, automatic mechanical follow-up devices, switches and counters for flow, pressure, differential, liquid level, constant temperature volume heat compensation, etc. The diaphragm valve is equipped with a flexible diaphragm or a combined diaphragm in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. The valve seat can be a weir shape or a pipe wall of a straight flow channel. The advantage of the pneumatic diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism.
What is the situation of pneumatic diaphragm valve leakage?
Pneumatic diaphragm valve is also something we often use, but do you really understand it? Can you solve some of the problems that arise with it? Next, the editor will briefly talk about the main reasons for the leakage of pneumatic diaphragm valves, hoping to help you.
Pneumatic diaphragm valves have to bear greater pressure during the opening and closing process. Sudden movements change the state of water flow. The pneumatic diaphragm valve gradually opens from the closed state to form a gap. The shear force generated by the water flow acts on the gate plate, cutting the edge of the gate plate. Multiple actions may cause the rubber ring to fall off or break, and the gate plate to have a gap, resulting in a loose valve.

1. The quality problem itself. The anti-corrosion layer of the gate plate and the gate body falls off or the anti-corrosion layer is thin, causing the gate body and the gate plate to rust, which can reach 30-50 mm, causing the gate plate to be unable to close or the sealing rubber strip on the gate body to be damaged by rust blocks falling off, resulting in a loose valve. The sealing rubber ring has quality defects, is not installed firmly or is too thin, causing the sealing rubber ring to fall off during the gate movement process;

2. Long-term immobility and inadequate maintenance of the pneumatic diaphragm valve cause the pneumatic diaphragm valve to be difficult to operate. The pneumatic diaphragm valve is inactive for a long time or has not been maintained, resulting in serious rust in the gate head or gate plate. After the rust scale falls off, the pneumatic diaphragm valve is loose and inconvenient to operate.
