[0002] Currently, the sealing test method for compressor valve plates involves filling the compressor's intake or exhaust chamber with gas at a certain pressure and then observing the pressure change to determine the valve plate's sealing performance. If the valve plate seals well, the gas pressure inside the chamber will drop only slightly within a specified time; conversely, if the gas pressure drops significantly, it indicates that the valve plate is leaking and has poor sealing performance.

The exhaust valve plate and intake valve plate on the valve plate are important structures related to the performance of the valve plate. However, testing the valve plate by installing it inside the compressor is easily affected by the gap between the valve plate and the cylinder, cylinder deformation and other factors, resulting in poor sealing and inaccurate test data.
