Mining DZ - Q liquid injection gun

DZ - Q liquid injection gun

DZ - Q liquid injection gun, individual hydraulic prop fluid injection gun,

liquid injection gun.

DZ - Q liquid injection gun works: at the beginning of the supporting force note liquid gun into three body, card prison lock set, tightening up the grip handlers, drive for hydraulic push rod, open for hydraulic oneway valve, high pressure fluid along the way for the pressure gauge, a path of high pressure release device cavity hole, liquid pipe, three

with injection valve pillar into inferior vena, pillar live cylinder force increases, when the end of the pillars and the top beam contact, close to the roof, depending on the pressure gauge index size; If the pressure reaches the provisions of this working face roof

pressure, speed stop for liquid, external driving force, moment driverunload coping bar, open the pressure relief valves, high pressure fluid by releasing hole eduction, the

pressure in the gun is zero, well take a gun.

Product Introduction

DZ-Q1 liquid injection gun is a constant pressure liquid injection gun suitable for coal mine hydraulic prop. The liquid injection gun by a liquid injection nozzle, retaining ring inlet tube, the gun, the differential piston, the control lever, adjusting nut, manual device, springs and other components. With differential piston lock control lever, open the inlet valve, the lock mode is mechanical. When the initial hydraulic prop support force reaches a predetermined value, the differential piston automatically discharged by the hydraulic differential lock, close the inlet valve. Device can also be manually close the inlet valve. The constant pressure liquid injection gun can be adjusted by adjusting the spring force of the size of the nut, adjust the initial hydraulic prop support force.
