Principle of operation

When the outdoor air valve is started from a static state, the sealing block 108 is positioned at the center of the valve cavity 109, and air flow can be smooth. When the valve needs to be closed but the threaded pipe 205 and the screw rod 203 are rusted, the push handle 207 is rotated, the bayonet pin 204 is pushed to move towards the side away from the push handle 207 to release the threaded pipe 205, the threaded pipe 205 is bounced under the action of the valve rod spring 106, and the sealing block 108 is attached to the upper surface of the valve cavity 109 to close the gas path.
