AI Technical Summary
During the manufacturing process of existing gas valves, a squid is prone to occur on the arc fitting surface, resulting in poor sealing of the air pipe.
Axial grooves are provided on the intake seat of the gas valve, including a radial surface and an arc surface, and statically ensure that there is a spacing between the two ends of the arc-shaped curved surface of the cylindrical gasket and the axial groove. When the air pipe is embedded, both ends of the arc-shaped curved surface enter the axial groove.
It reduces the occurrence of edges during the manufacturing process and improves the sealing of the air pipe and the arc-shaped fitting surface.
