Large-space efficient fire-extinguishing device

Abstract

The invention discloses a large-space efficient fire-extinguishing device. The large-space efficient fire-extinguishing device comprises a water storage tank, a high pressure water pump, a high pressure water delivery pipe and a water spray pipe which are sequentially connected in series, and further comprises a water mist spray nozzle which is connected with the end part of the water spray pipe, wherein the water mist spray nozzle comprises a base, and a nozzle body provided with a spray nozzle hole and arranged on the base; a hollow cylindrical cavity is arranged inside the nozzle body; a conical surface is arranged at the top of the cavity; the spray nozzle hole is formed in the vertex of the conical surface; an atomizing core comprising a core seat and a core body is arranged in the cavity; the core seat is in a racetrack shape and is connected with the cavity through threads; the core body is arranged on the core seat and is cylindrical; a blind hole is formed in the top of the core body; a first conical surface matched with the side wall of the conical surface of the cavity and at least two diversion grooves formed in a staggered way along the periphery of the blind hole are formed in the top surface of the core body on the periphery of the blind hole; one end of each diversion groove is communicated with the blind hole; the other end of each diversion groove is communicated with the cavity. The large-space efficient fire-extinguishing device is better in suffusion effect, small in water consumption, good in atomization effect and high in fire extinguishing efficiency.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a large-space high-efficiency fire extinguishing device. Background technique [0002] The large-space high-efficiency fire extinguishing device is a new type of automatic fire extinguishing system developed in recent years. It solves the protection problems of flammable liquid fire hazard places and cables and electrical appliances fire hazard places. Due to the remarkable fire extinguishing effect of fine water mist, it is widely used in hydraulic stations, lubricating oil depots, turbine oil depots, oil-immersed power transformers, diesel generator rooms, boiler rooms and other places. However, the high-efficiency fire extinguishing devices with large spaces in the prior art still have deficiencies, and the mist generation method of high-pressure ultra-fine water mist is still relatively simple. At present, the formation methods of fine water mist in common nozzles are divided i...
