What Do You Need To Know Before Analyzing The Cause Of The Sanitary Diaphragm Valve Leakage Problem?
Sanitary Diaphragm Valve is controlled remotely by a drive device or manually operated by a handle. The drive device has three standards: normally closed, normally open and air-to-air. It has the advantages of simple structure, beautiful appearance, quick disassembly and assembly, flexible operation, small fluid resistance, safe and reliable use. It is suitable for the control of water, gas, oil and corrosive media in chemical, petroleum, metallurgy, water heating, food, medicine and other industries.
Why does the sanitary diaphragm valve leak?
Before analyzing the cause of the sanitary diaphragm valve leakage, we must first understand its basic structure. It is a flexible diaphragm or a combined diaphragm 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 spray system and is directly related to the dust removal effect of the dust removal equipment.
The reasons for the leakage of the sanitary diaphragm valve are as follows:
1. Damage to the diaphragm valve diaphragm.
2. The gasket of the diaphragm valve diaphragm cannot fit tightly with the end face of the air outlet, resulting in leakage of the solenoid valve.
3. For the submerged diaphragm valve, if there is a hole in the nozzle in the air bag, the compressed air will leak directly into the spray pipe without passing through the diaphragm valve.
4. The diaphragm valve diaphragm 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 the sanitary diaphragm valve. When checking the problems one by one, you can quickly eliminate the problems so that you can engage in production work normally.
