Multifunction recoilless recoilless gun fire water: QDL8 type adjustable nosepiece recoilless multifunction reaction ≥0.8Mpa main solution to underwater pressure fire extinguisher for the fire, the firefighters can reduce labor strength. Spray gun point to ensure the accuracy of fire, water gun also can regulate the flow, regulate the flow state, anti-water stop twisting knot and is suitable for use multiple occasions, and improve fire effects. The gun appearance, light weight, high strength, long life, easy to operate fire hose reel box, is an ideal choice for firefighters extinguishing gun. 1. Model QWKT8.0B150-550 caliber mm65 rated water flow pressure Mpa 0.8 L / s150 ~ 550 DC range m≥34 spray range m≥1 reaction N9.8 2. Model QWKT6.0C-780 large-diameter water flow mm65 rated flow pressure Mpa 0.8 L / s380 ~ 780 DC range m≥44 spray range m≥22 reaction N11.5 100X remote control float valve float valve remote control remote control float valve by rotating the valve love to make the valve flow or occlusion. Valve switch light, small size, can be made into large-caliber, reliable sealing, simple structure, easy maintenance, and spherical sealing surface often in the closed state fire extinguisher box, can not easily be eroded media box, in various sectors has been widely used. Folding work process A, the opening process 1 in the closed position, the mechanical pressing action by the ball stem, pressed against the valve seat. 2 When the handwheel counterclockwise stem the reverse movement, its flat bottom corner to make the ball disengage the seat. 3 stem continues to rise, and with the stem of the spiral groove of the guide pin interaction respirators extinguisher box, make the ball start to rotate without friction. 4 up to the fully open position, the valve stem to the limit position, the ball rotated to the fully open position. B, when the shutdown process a closed hand wheel clockwise, the stem and the ball began to fall away from the seat starts to rotate. 2 continues to rotate the handwheel stem being embedded in the spiral groove on its role of guide pins, so the stem and ball while rotating 90 °. 3 is about to shut down, the sphere has been in the case of non-contact with the valve seat is rotated 90 °. The last four laps hand wheel rotation, angular plane mechanically wedge at the bottom of the stem to the oppression of the ball, making it tightly pressed on the seat, to be completely sealed.
