description The utility model discloses a gas intake and exhaust valve for a natural gas compressor. The gas intake and exhaust valve comprises a valve body, wherein a gas inlet is axially formed in one end of the valve body, and at least one gas outlet is radially formed in the sidewall of the valve body; an end cover is mounted at the other end of the valve body, a spring is fixedly arranged on the end cover, the other end of the spring is connected with one end of a valve core, a cone-frustum-shaped choke plug is arranged at the other end of the valve core, the diameter of the upper bottom face of the cone-frustum-shaped choke plug is smaller than that of the gas inlet, and the diameter of the lower bottom face of the cone-frustum-shaped choke plug is greater than that of the gas inlet. According to the gas intake and exhaust valve for the natural gas compressor, the clearance of a compression chamber of the compressor can be effectively reduced, and the efficiency of gas compression is increased; due to the adoption of a plug-mounted structure, the replacement is convenient, the structure is simple, and the cost is low.
