Description

TECHNICAL FIELD

[0001] The utility model relates to a compressor air valve technical field, specifically a compressor air valve with better sealing performance. BACKGROUND

[0002] The compressor air valve is a key component in the compressor system, and its main function is to control the entry and exit of gas in the compressor cylinder. It is realized through opening and closing actions, that is, opening or closing the gas passage at the appropriate time to ensure the effective operation of the compressor. The compressor air valve is an automatic valve, usually installed on the cylinder of the compressor, used to control the flow of compressed and discharged gas. The operation of the compressor air valve is usually based on the pressure difference principle. When there is a difference between the pressure in the cylinder and the pressure in the valve cavity, the pressure difference will cause the air valve to automatically open or close. In the piston compressor, the air valve is usually not forcibly driven, that is, it is not controlled by external mechanical devices, but relies on the gas pressure difference and spring force to realize automatic opening and closing.

[0003] The patent document with the application number CN201821350819.0 discloses a compressor air valve, which includes a valve cover and a valve seat connected coaxially. The valve seat is provided with multiple rings of valve seat air holes, which are coaxially arranged. The valve cover is provided with valve cover air holes corresponding to the valve seat air holes. Each ring of valve seat air holes is provided with a ring of valve pieces that cover them. The valve pieces are located between the valve cover and the valve seat. Compression springs are arranged between the valve pieces and the valve cover to keep the valve pieces covering the valve seat air holes. Radial connecting rods are connected between adjacent rings of valve pieces. The above structure provides a compressor air valve with a more reasonable structure and lower production and maintenance costs. Based on the above patent search and combined with the existing compressor air valve, it is found that the wear and aging of the air valve material or design defects can cause the sealing performance of the air valve to decrease, affecting the normal operation and efficiency of the compressor. In addition, in a high-pressure and high-speed working environment, the air valve is prone to fatigue damage, resulting in a high failure rate. UTILITY MODEL CONTENT
