AI Technical Summary
Technical Problem
When the pneumatic switch valve is closed, it is easy to suck out rainwater from outside, causing water accumulation in the cylinder, affecting the valve opening performance, and may lead to capacity loss or failure and shutdown.
Method used
A single-acting pneumatic switch valve is designed, using a pneumatic sealing shell and rainproof cover structure to prevent rainwater from entering the cylinder and maintain air circulation through the dust filter cleaning structure.
Benefits of technology
It effectively prevents water accumulation in the cylinder, ensures that the valve operates stably outdoors for a long time, reduces the problem of poor opening caused by water accumulation, and improves air circulation.

Abstract
The utility model relates to the technical field of pneumatic switch valves, and specifically to a single-acting pneumatic switch valve capable of preventing water ingress, comprising: a valve body; a pneumatic sealing cover is installed at the top end of the valve core rod of the valve body, and an air cavity for piston compressed air is provided on the inner wall of the pneumatic sealing cover; a driving cylinder is installed on the piston inside the air cavity; an air inlet hole and an air outlet hole are provided in the air cavity of the pneumatic sealing cover; the air inlet hole is sealed with a rear cavity air port, and the rear cavity air port is connected with a compressed air pipe, the compressed air pipe is sealed and connected with a pneumatic solenoid valve, and a solenoid valve air inlet pipe is installed at the air inlet of the pneumatic solenoid valve. In the utility model, after the main rotating rod is rotated, the top brush holder 1, the bottom brush holder and the top brush holder 2 are used to rub and clean the dust on the upper and lower surfaces of the dust particle filter and the bottom surface of the desiccant filter, thereby reducing the problem of blockage of the solenoid valve air inlet port, which leads to reduced air circulation.
