Liquid injection gun

The liquid injection gun is a liquid injection tool used when injecting liquid into a single hydraulic prop. It is simple, convenient and suitable to use. The liquid injection gun used for mining single hydraulic props includes: valve body, locking sleeve, handle, ejector rod, isolation sleeve, one-way valve seat, steel ball, spring, compression screw, liquid outlet, in the valve The rear end of the body is connected to the liquid inlet pipe by a joint, and the handle is connected to the valve body through a pin. The isolation sleeve, one-way valve seat, steel ball, and spring are sequentially installed in the rear part of the valve body. The outside of the liquid tank is sealed by a sealing plate. There is a forward liquid hole in the front of the valve body, and a rear liquid hole and a semicircular arc flow tank are provided on the isolation sleeve. The forward liquid hole and the rear liquid hole pass through The liquid tank is connected, the processing technology is relatively simple, and it has the characteristics of compact structure, small volume, and good sealing performance.
The liquid injection gun is the terminal of the piping system of the pumping station. Through it, high-pressure liquid is input into the working chamber of the unit pillar to complete the pillar lifting and initial support process. The liquid injection gun is an accessory for the external injection single hydraulic prop in mine support. It is a must-use accessory in mine support.

Liquid injection gun consists of
: valve body, pressure gauge, operating handle, pressure relief plug, unloading valve, pressure relief ejector rod, liquid injection pipe, locking sleeve, liquid supply top It consists of rod, isolation sleeve, liquid supply valve seat, liquid supply pipe, etc.

Parameters of the liquid injection gun
: Working pressure of the liquid injection gun: - Handle force of the liquid injection gun when injecting liquid:
3
Working of the liquid injection gun Principle:
The liquid injection gun injects the emulsion into the single pillar through the three-way valve so that the single pillar supports the tunnel.
