Water-atomizing fire-control nozzle and spray head as well as fire-extinguishing apparatus

Abstract

The invention discloses a water-atomizing fire-control nozzle and a spray head as well as a fire-extinguishing apparatus. The nozzle comprises a main body structure and a spraying spiral body, wherein a spray port is formed in one end of the main body structure; the spraying special body is arranged in an inner cavity of the main body structure; a fluid channel is formed by the spraying spiral body and the main body structure; the fluid channel comprises a liquid inlet section, a spiral power section and a liquid storage section, wherein the liquid inlet section, the spiral power section and the liquid storage section are communicated in a fluidic manner; the liquid storage section is communicated with the spray port; the spiral power section comprises a plurality of spiral channels; and the sum of the section areas of the plurality of the spiral channels is smaller than the section area of the liquid inlet section. The water-atomizing fire-control nozzle and the spray head as well as the fire-extinguishing apparatus disclosed by the invention can be operated under low water pressure, so that the cost is reduced, the energy is saved and the environment is protected.

Description

technical field [0001] The invention relates to the field of fire-extinguishing equipment, in particular to a fine water atomization fire-fighting nozzle, a spray head and fire-extinguishing equipment. Background technique [0002] At present, the awareness of environmental protection is very important at home and abroad. Many countries have done a lot of work on fire protection and environmental protection. Water is the most environmentally friendly and safest fire-fighting material. In recent years, many countries have developed water mist fire extinguishing systems, such as Danfoss ( Danfoss), most of them can be realized under high pressure. Its working pressure is generally around 8-10MPa (80~100bar). The disadvantage is that the water pump under high pressure requires high requirements, which brings high requirements for water quality, electric power, and piping systems. . Contents of the invention [0003] The main technical problem to be solved by the present inve...
