Description

Technical Field

[0001] The utility model belongs to the technical field of air compressor components, and specifically relates to an air compressor vent valve device. Background Technique

[0002] An air compressor is a basic product of industrial modernization. The so-called electricity and automation have the meaning of full pneumatic; and the air compressor is to provide air source power, which is the core equipment in the pneumatic system and the main body in the mechanical and electrical air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy and is a pneumatic pressure generating device for compressed air.

[0003] After the air compressor stops, the internal pressure needs to be released outward through the vent valve. For example, the Chinese patent discloses a vent valve, the publication (announcement) number: CN206145138U, which includes a valve body, a valve seat, a pressing plate, a valve sleeve, a valve core, a valve rod and a handwheel; the valve seat is arranged in the valve body and divides the valve body into a first valve body and a second valve body. The valve sleeve is provided with a medium inlet, the pressing plate is provided with a medium hole, the valve sleeve is arranged in the first valve body and connected to the valve seat, the valve core is sleeved in the valve sleeve and connected to the pressing plate, one end of the valve rod is connected to the valve core, and the other end extends outside the first valve body and is connected to the handwheel. The handwheel can drive the valve core connected to the valve rod to rise or fall in the valve sleeve, so that the valve seat is conducted or cut off. The vent valve provided by the utility model can play a role in balancing the medium pressure in the vent valve and prevent the problem of the valve rod being bent due to excessive resistance, resulting in a failure. The above patent can play a role in balancing the medium pressure in the vent valve during use, but it cannot be automatically switched on and off, resulting in the operator needing to manually rotate it during use, and it cannot be automatically switched on and off, thus affecting the normal use of the operator.
