CN103879533Ath, Chinese patent, the core component that fluid power hits big gun is Far Range fire water monitor.Large discharge water cannon is also installed in fire boat, and it is applied in offshore drilling platform and transports the port and pier of natural gas, oil, and the flow of this kind of fire water monitor can reach 1500m usuallyģ/ more than h, range is at more than 130m, and how under identical water cannon input flow rate pressure condition, the maximum range improving such fire water monitor is one of difficult point of water cannon design, is also important developing direction. Descriptionįire water monitor is modal extinguishing device in fire-fighting equipment, land fire water monitor and fire water monitor peculiar to vessel two kinds can be divided into according to use occasion, limit by water consumption, " control fire monitor system general technical specifications GB 19157-2003 far away " defines land fire water monitor maximum stream flow is 720mģ/ h, range is not less than 110m.And fire water monitor peculiar to vessel, because marine engine power is comparatively large, pump group pressure flow, much larger than land fire water monitor, has possessed conveniently water supply conditions, thus can be equipped with more large discharge, more long-range fire water monitor.External maritime patrol ship uses military firearm for avoiding, prevent from resisting against law violently, be provided with the marine explosion-proof fire monitor of Far Range large impact power, for the fishing boat of expelling illegal smuggling, illegally fish for, sea rover etc., play deterrent effect, in " the anti-climbing fluid power percussion device of a kind of boats and ships " disclosed in No. The despin device comprises a fire water monitor head, a spray tube, a flow straightener, a bent tube I, a bent tube II and a despin sheet, wherein the bent tube I and the bent tube II are connected by a flange structure the eccentric part of the despin sheet is welded on the inner part of the bent tube I the flow straightener is arranged on the inner part of the spray tube in a sleeving mode, and is welded and fixed by a welding process the fire water monitor head is arranged on the spray tube in a threaded connection mode a sawtooth type micro guide slot is processed in a runner inside the fire water monitor head for reducing flow resistance at a spray nozzle and through co-action of the despin sheet inside the bent tube I, the flow straightener inside the spray tube and the micro guide slot in the spray nozzle, the range of the long-range straight-flow type fire water monitor can be remarkably increased. The invention discloses a despin device for a long-range straight-flow type fire water monitor and a processing process.
