Liquid injection gun

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 in 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 Port, use a joint to connect the liquid inlet pipe at the rear end of the valve body, the handle is connected to the valve body through a pin, and the isolation sleeve, one-way valve seat, steel ball, and spring are sequentially installed in the rear of the valve body. There is a liquid groove on the body, and the outside of the liquid groove 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 groove are installed on the isolation sleeve. The forward liquid hole is connected with the The rear liquid inlet hole is connected through the liquid tank, 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 pumping station pipeline system. 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, liquid injection pipe, locking sleeve, liquid supply ejector, isolation sleeve, liquid supply It consists of 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 principle of the liquid injection gun:
The liquid injection gun passes The three-way valve injects the emulsion into the monomer pillar so that the monomer pillar supports the tunnel.
