How to operate the pneumatic fluorine lined diaphragm valve reasonably? We must come up with a good solution to this issue. Let's take a look at the knowledge in this area.
1. The flange cover plate of the pneumatic fluorine lined diaphragm valve cannot be opened arbitrarily unless it is prepared to be connected to the pipeline. Otherwise, the PTFE flange surface may be damaged, scratched or twisted due to temperature difference or foreign objects, which may affect the sealing. If the cover plate needs to be moved for inspection, it must be quickly reset after inspection to protect the PTFE flange surface.
2. When connecting pneumatic fluorine lined diaphragm valves with pipelines, gaskets are generally not used separately. However, when connecting with flange surfaces made of different materials (such as metal surfaces), appropriate gaskets should be used to protect the PTFE flange surface.
3. If the pneumatic fluorine lined diaphragm valve leaks at high temperatures during system use, the system temperature should be lowered to room temperature first, and then the cause should be identified and repaired.
4. No high-temperature welding work is allowed on the pneumatic fluorine lined diaphragm valve to avoid damage to the lining layer.
5. Pneumatic fluorine lined diaphragm valves should be stored in a dry and ventilated room, and stacking is strictly prohibited.
6. The sealing pair of the pneumatic fluorine lined diaphragm valve stored for a long time should be in a slightly separated state to avoid deformation of the sealing surface due to long-term compression, which may affect the sealing performance and service life.
The above is an introduction to the operation of pneumatic fluorine lined diaphragm valves.
