Description

Air vent device for hydraulic pump

The present invention relates to an air vent device of a fluid pump, and more specifically, to form an air vent device that can introduce external air by pressurization on the upper part of the pumping port of the fluid pump, remaining in the suction pipe and discharge hose after the pumping operation It is designed to easily drop the fluid.

In general, the fluid pump is a mechanism that can suck the fluid inside the container by the suction force generated by the pumping operation of the pumping port and then discharge it through the discharge hose on the other side.

And, typically, the pumping port body of the fluid pump is provided with an air vent device capable of dropping the remaining fluid to the inflow of external air after being moved upward by the suction force in the suction pipe and the discharge hose after the pumping operation.

Since the residual fluid is removed, there is a problem that air vent workability is lowered.

In addition, since the sealing cap for controlling the air inlet groove of the pumping hole is installed in a screw fixing method, the sealing cap is not easily released due to the adhesion of foreign substances such as dust after a long time, so that the air vent work may be performed by some workers. In the meantime, the residual fluid leaked during the movement and storage of the fluid pump, thereby reducing the surrounding environment.

An object of the present invention is to form an air vent device that can introduce external air by pressurization on the upper part of the pumping port of the fluid pump, so that the fluid remaining in the suction pipe and discharge hose after the pumping operation can be easily dropped To provide an air vent device.
