[0002] The compressor valve plate is a component of the compressor. The quality and accuracy of the compressor valve plate directly affect the life of the compressor and the refrigeration effect. The valve plate is the part of the compressor that is most subject to impact and must meet the following standards: the design of the valve plate must meet the various requirements of the compressor manufacturer; the valve plate material must be precision stamped; the seal between the valve plate and the valve seat must be good; long-term stable performance is the most important; the elasticity and recovery of the material.

[0003] Although the current compressor suction valve plate can enable the compressor to inhale air when in use, there are still some shortcomings in its use. For example, during the suction process of the compressor, due to the entry of gas, one side of the suction valve plate will be separated from the compressor connecting valve body, and the suction valve plate is difficult to quickly reset after the suction is completed, resulting in gas leakage during use. For this reason, we propose a compressor suction valve to solve the above problems. Utility Model Content

The top end of the sliding rod 18 is fixedly connected to the limiting plate 11. The spring 17 can be limited by the sliding rod 18 and the sliding hole 12 to prevent the spring 17 from being deformed. The upper surface of the top plate 19 and the bottom surface of the top plate 19 are fixedly connected with reinforcement strips 20, and the left side surface of each reinforcement strip 20 is fixedly connected to the right side surface of the connecting plate 5.
