How to solve the problem of vacuum ball valve leakage?

If the vacuum ball valve leaks, it will cause the entire production line to not work properly, which will have a serious impact on the economic benefits of the enterprise. How to solve the problem of vacuum ball valve leakage? The traditional vacuum ball valve leak detection methods are water inspection method and pressure method.

Water inspection method. This method is the simplest and most primitive method of leak detection. The working principle is to fill the tested workpiece with air larger than the air pressure, and then put it in the water to see if there is a bubble emerging from the water. The bubbling position is the leaking position, and the leakage can be estimated according to the bubbling rate and the size of the bubbling. Size, need to dry after testing.

Pressure method. The vacuum ball valve is connected to the vacuum ball valve by using a compressor or compressed air, sealed after inflation, and observes the pressure of the vacuum ball valve within 24 hours. If there is a leak, the pressure will decrease, but it cannot be judged where it leaks or Know the size of the leak. This method has low sensitivity and can only detect large leaks, and can not detect specific leak points. Therefore, there are many disadvantages.
