Overview of diaphragm valve

Date:2024-06-12 Click:533

Diaphragm valve is a valve that regulates the flow of fluid through a flexible diaphragm. It is widely used in various industrial fields, especially in industries with high requirements for sanitary conditions, such as food, medicine and chemical industry. Diaphragm valves have the advantages of no leakage, small flow resistance and easy maintenance. The following is the use and maintenance of diaphragm valves.
I. Overview of use:
Applicable media: Diaphragm valves are suitable for handling corrosive media, media containing solid particles and media requiring high sanitary conditions, such as food, medicine and pure water.
Installation position: Diaphragm valves can be installed on horizontal or vertical pipes, but it should be ensured that the flow direction indicated by the arrow on the valve body is consistent with the actual flow direction of the medium.
Operation mode: Diaphragm valves can be operated manually, electrically or pneumatically, and the appropriate drive mode should be selected according to actual needs.
Switch state: Diaphragm valves are generally used in full open or full closed states, and long-term use in the adjustment state should be avoided to reduce the wear and deformation of the diaphragm.
II. Maintenance overview
Regular inspection:
External inspection: Regularly check whether there are leaks, corrosion or other signs of damage on the outside of the valve body.
Internal inspection: Regularly check the wear and aging of the diaphragm to ensure that it is not damaged or deformed.
Cleaning:
Internal cleaning: remove impurities and dirt that may accumulate inside the valve, especially when handling media containing solid particles, cleaning should be performed more frequently.
External cleaning: keep the outside of the valve clean to prevent external dirt from entering the valve and affecting its normal operation.
III. Professional maintenance:
For diaphragm valves in key equipment, it is recommended to ask professionals to perform maintenance and inspection regularly to ensure that they are in the best working condition.
Through the above-mentioned use and maintenance measures, the normal operation of the diaphragm valve can be effectively guaranteed, its reliability and service life can be improved, and the safety and stability of the fluid control system can be ensured.
