Mine DZ-Q1 hot liquid injection gun, mining liquid injection gun models, hydraulic prop gun DZ-Q1 liquid injection liquid injection gun I produced liquid injection gun is a new beginning supporting force controlled automatic injection liquid gun, ideal for hydraulic prop in coal mines. A, DZ-Q1 liquid injection gun consists of: the gun, the liquid supply tube, the operating handle, for the fluid check valve assembly and other components. Two, DZ-Q1 liquid injection gun features; ① small size, light weight, low cost, ② has strong practicability. Third, the working pressure range: ① 0 to 40Mpa, the medium is emulsion; ② relief methods: extrapolation handle relief. Fourth, it works: the initial setting load the gun into the liquid injection valve with three on the card firmly tighten the locking sleeve, the inner grip handle operation, the drive for the fluid ejector, opened for liquid check valve, high pressure liquid all the way for pressure gauge, pressure release device by the upper chamber inclined hole, liquid injection tube, three valves inject pillar lower chamber, forcing the pillars of live cylinder increases, when the top head and the roof pillars beam contact, close the roof, depending on the pressure gauge index Size; required if the pressure reaches the roof face pressure, speed stop for the fluid, and instantly extrapolation handle, pressure relief plunger drive, open the pressure relief check valve, high pressure fluid is discharged through the discharge opening, gun pressure is zero, the smooth take gun. Shandong HRCA to the state, society and the customer is responsible for the principle, for your dedicated service!
