Before analyzing the cause of the air leakage problem of Sanitary Diaphragm Valve, we must first understand its basic structure. A flexible diaphragm or a combined diaphragm is installed 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-through flow channel. The advantage of the sanitary 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.

The sanitary diaphragm valve is one of the cleaning components of the pulse bag dust collector. It is the compressed air "switch" of the pulse bag dust collector cleaning and blowing system and is directly related to the dust removal effect of the dust removal equipment.

The reasons for the air leakage of the sanitary diaphragm valve are as follows:

1. Damage to the diaphragm of the diaphragm valve.

2. The gasket of the diaphragm of the diaphragm valve cannot fit tightly with the end face of the air outlet, resulting in air leakage of the solenoid valve.

3. For submerged diaphragm valves, if there is a hole in the nozzle in the air bag, the compressed air will leak directly into the blowing pipe without passing through the diaphragm valve.

4. The diaphragm of the diaphragm valve itself is of poor quality.

5. Fatigue damage caused by the long working cycle of the diaphragm valve.

The above five points are the reasons for the leakage of sanitary diaphragm valves. When checking the problems one by one, you can quickly eliminate the problems so that you can engage in normal production work.
