Claims

[Scope of utility model registration request]

A valve chamber attached to the outer shell of the air tank, a valve hole communicating with the valve chamber, and a valve seat formed in the communication portion between the valve chamber and the valve hole;
A valve body having a port opened in the side surface of the valve chamber and communicating with the atmosphere, a piston-shaped valve body fitted into the valve chamber and having a ring-shaped sealing material fitted to the end face and side face, and the valve body. and an adjustment screw screwed into the atmosphere-side opening of the valve chamber to adjust the pressing force of the spring, and the valve chamber communicates with the atmosphere side of the air tank. The valve hole is opened on the compressed air side, and when the internal pressure of the air tank is within a specified pressure, the valve body is pressed by the spring and seats on the valve seat, and the sealing material on the end and side surfaces connects the valve hole and the pole. The valve body is simultaneously closed, and when the internal pressure of the air tank exceeds a specified pressure, the valve body is pushed up against the pressing force of the spring, communicating the valve hole and the port, and releasing the internal pressure of the air tank to the atmosphere. air safety valve.
