The air valve of a single-acting compressor is usually installed on the cylinder head. As the core component of the compressor, the air valve directly affects the efficiency and life of the compressor. However, the air valve is a wearing part and must be replaced regularly. At present, the mainstream domestic valves use plate valves or concentric valves. These valves are not as efficient as mesh-mounted valves. Replacement requires disassembly of the cylinder head and pipelines, which is very inconvenient. Therefore, a new structure cylinder head with mesh-mounted valves that is easy to disassemble has been developed. Utility Model Content

The air flow channel is connected to the air inlet and the exhaust port on the surface of the cylinder head. Installation ports for installing a mesh-mounted air inlet valve and a mesh-mounted exhaust valve are symmetrically provided on both sides of the middle of the cylinder head.

[0006] The intake pressure valve cover includes a flange part A and a cover body part A. The flange part A is installed on the side wall in the middle of the cylinder head by bolts. The outer wall of the cover body part A cooperates with the inner wall of the mounting port provided in the cylinder head, and a sealing ring A is provided at the connection. The cover body part A is sleeved on the mesh-mounted intake valve.

[0007] The exhaust pressure valve cover includes a flange part B and a cover body part B. The flange part B is installed on the side wall in the middle of the cylinder head by bolts. The outer wall of the cover body part B matches the inner wall of the mounting port provided in the cylinder head, and a sealing ring B is provided at the connection.
