The purpose of the utility model can be realized by the following technical proposal: a movable screw air compressor instrument valve comprises a valve body and a damping pipe, wherein the valve body is communicated with the damping pipe through a nut, the damping pipe is arranged on an air storage tank of an air compressor, it is characterized in that the top of the valve body is provided with a counter bore, an air pipe joint is arranged in the counter bore, a first spring seat, a first valve ball and a plug are sequentially arranged in the air pipe joint, and is fixed by an inner step to form a one-way valve, an instrument joint communicated with the inside of the valve body is arranged on the side of the valve body, a second spring seat and a second valve ball are sequentially arranged between the instrument joint and the valve body, a slidable push rod is arranged in the instrument joint, the push rod and the inner wall of the instrument joint are provided with gaps, the outer end part of the instrument joint is hinged with a connecting pipe, the connecting pipe is of a hollow structure, and one end of the connecting pipe is matched with the port part of the instrument joint.
In the above movable screw air compressor instrument valve, a sealing gasket is arranged between the counter bore of the valve body and the air pipe joint.
In the above instrument valve of the movable screw air compressor, an air release screw is arranged on the side of the damping tube.
In the above instrument valve of the movable screw air compressor, the joint surface of the connecting pipe and the instrument joint is of a cambered surface structure.
This instrument valve passes through the damping tube and installs the output that realizes atmospheric pressure simultaneously on the gas holder to gas outlet department at the valve body sets up the check valve, makes gas can only toward outer one-way circulation, in the inside liquid flow in the gas holder of pipeline when preventing the equipment stagnation, also prevent that outside dust from pouring backward into in the gas holder, it is concrete, the utility model discloses for traditional instrument valve main improvement for set up the instrument joint in valve body side, the manometer is installed on the connecting pipe, when needs show internal pressure, pushes down the connecting pipe and makes it and instrument joint to it, and form sealedly at the composition surface, the push rod this moment is because external pressure is pushed in, pushes up two of valve ball of instrument joint port department and opens and make it be in the circulation state, and the manometer shows the inside atmospheric pressure of gas holder. At ordinary times, the connecting pipe and the instrument connector are in a bent state, the push rod pushes the air storage tank out through the valve ball II due to the internal pressure of the air storage tank, and the valve ball II is matched with the port of the instrument connector to form sealing.
Compared with the prior art, the movable screw air compressor instrument valve has the following advantages:
1. the combination is good, namely the air outlet valve, the instrument valve and the air release valve are arranged on one valve body, the whole structure is more compact, the arrangement of interfaces on the air storage tank is reduced, and the sealing performance is better;
2. convenient to use, the manometer uses the hinge structure rotation that makes directly pass through the connecting pipe to show the inside atmospheric pressure of gas tank at needs, is in the state of placing that hangs down at ordinary times, is difficult for bumping at the portable to also can directly dismantle, the use on portable air compressor is convenient for in the repacking during needs.
