Description
Technical Field
The utility model relates to the technical field of automobile part testing equipment, in particular to an air valve air leakage detection device.
Background
The air valve is a component used for controlling air to enter and exit the cylinder in the compressor and mainly comprises a valve seat, a valve plate, a spring and a lift limiter, and the lifting height or the closing between the valve plate and the valve seat determines the size and the sealing of an air channel.
For example, chinese patent application CN103124872B discloses a gas valve comprising a gas hood having an inlet, an outlet and a passage opening communicating the outlet with the inlet; a valve seat cooperating with the passage opening to close the passage opening; an internal device connected to an exterior of the valve; a connection device through which the internal device is communicated or connected to the outside of the valve; and elastic means closing the gas hood in a sealed manner. The valve further comprises a metal printed circuit board housed in the second body, the metal printed circuit board being connected to the internal device and comprising a connection area with a connection device.
It is noted that the valve also comprises an externally operated actuator therein, and which preferably comprises a switch.
