Ultra-wide-pressure fine water mist spray head

Abstract

The invention discloses an ultra-wide-pressure fine water mist spray head. The ultra-wide-pressure fine water mist spray head comprises a spray head body, wherein a screw plug and a filter screen arearranged at the rear end of the spray head body, a conical surface is arranged on the front end surface of the spray head body, a plurality of nozzles are uniformly distributed on the upper circumference of the conical surface, a swirler is arranged in each nozzle, the swirlers are in threaded grooving and are pressed tightly and mounted in the nozzles by means of spirals, the nozzles are providedwith conical flow channels, a plurality of circumferentially tangent grooves are formed inside each swirler and are fastened and connected with the nozzles through the grooves to prevent water leakage, the screw plug is a cylindrical head screw plug and is in threaded connection with the spray head body, and the filter screen is connected with the screw plug. Under the low medium-high pressure, sprayed water is atomized by the aid of a vortex principle, mist particles are uniform in uniformity, mist drop particles are smaller than 100 micrometers, the spray coverage range is wide, and the application range is wide, therefore, the spray head can be applied to a medium and high pressure water supply system to achieve a strong atomization effect, and also can solve the problem of poor low pressure atomization effect in a gas cylinder pressurized water supply system with insufficient water supply.

Description

technical field [0001] The invention relates to a fire sprinkler, in particular to an ultra-wide pressure fine water mist sprinkler. Background technique [0002] In view of the serious damage effect of halogenated alkane (also known as halon) fire extinguishing agent on the atmospheric ozone layer, after the 1980s, the United Nations successively issued the "Vienna Convention for the Protection of the Ozone Layer" and the "Montreal Protocol" to achieve a complete ban on the production and use of halogenated hydrocarbons for fire extinguishing instead of water-based fire extinguishing agent, foam fire extinguishing agent, dry powder fire extinguishing agent, carbon dioxide fire extinguishing agent and metal fire extinguishing agent. Compared with other fire extinguishing agents, water-based fire extinguishing agents are low in cost, efficient, clean and pollution-free. After signing contracts, various countries vigorously develop fire extinguishing systems using water-based...

Problems solved by technology

[0011] In the prior art, there are many types of products with nozzle pressure classification; the nozzle works at high pressure; the system pressure fluctuates, and the fire extinguishing performance is affected when the fire situation is complicated

Traditional fine water mist nozzles cannot realize the application of medium and high pressure and low pressure at the same time. If a strong atomization effect is required, the fire extinguishing system uses a medium and high pressure water pump to supply water; for insufficient water supply, or in some special occasions, the gas cylinder pressurized water supply method is used. But the atomization effect of this type of nozzle is very poor
