Safety fire water branch adjustable in jet flow status, and debugging method and usage method thereof

Abstract

The invention discloses a safety fire water branch adjustable in jet flow status. The safety fire water branch adjustable in jet flow status comprises a cylindric housing, wherein one end of the cylindric housing is provided with a water supply connector, the other end of the cylindric housing is provided with an injection nozzle, an electromagnetic valve for water supplying, an air inlet pipe, awater baffle, a metal net and an electromagnetic needle valve are sequentially connected with the cylindric housing between the water supply connector and the injection nozzle along the direction fromthe upstream to the downstream, the air inlet pipe is used for connecting an external vent pipe and guiding carbon dioxide gas into the cylindric housing, and a water guiding hole is formed in the middle of the water baffle. The invention further discloses a corresponding debugging method and a corresponding usage method of the safety fire water branch adjustable in jet flow status. The safety fire water branch adjustable in jet flow status and the debugging method thereof provide a basis for achieving automatic adjustment and achieving excellent firefighting effect. The usage method is simple and efficient, can automatically enable opening degrees of the electromagnetic needle valve and the electromagnetic valve for the water supplying to adapt to a current jet angle and fire source distance without need for manual intervention, shortens firefighting preparation time, and obtains excellent firefighting effect.

Description

technical field [0001] The invention relates to the field of fire-fighting tools, in particular to a fire-fighting water gun. Background technique [0002] With the acceleration of urbanization in our country, urban buildings are becoming taller and denser. When an urban building fire occurs, the fire will increase and spread rapidly in a short period of time, which poses new challenges to the urban fire protection work. [0003] The fire nozzle is the core component of the sprinkler system. When extinguishing a fire, in addition to ensuring the sprayed water volume of the fire nozzle, a certain spray pressure should also be ensured to obtain a larger spray distance, thereby improving the fire extinguishing efficiency. [0004] According to the situation and properties of the fire scene, it is often necessary to use a mixture of water and carbon dioxide gas-liquid to extinguish the fire. However, the existing structure of the fire water gun can simply provide the mixture of...

Problems solved by technology

[0004] According to the situation and properties of the fire scene, it is often necessary to use a mixture of water and carbon dioxide gas-liquid to extinguish the fire. However, the existing structure of the fire water gun can simply provide the mixture of water and carbon dioxide gas-liquid, but it cannot effectively adjust the jet flow state of the water gun according to the fire scene. Or a water-air mixture that can adjust the jet state but cannot spray water and carbon dioxide at the same time

This situation not only wastes a lot of water and carbon dioxide resources during fire extinguishing operations, but also has poor fire extinguishing effects, resulting in secondary water pollution and carbon dioxide pollution.

Due to the single way of spraying water, it is necessary to replace the gun head in some occasions, which affects the timing of fire extinguishing, reduces the efficiency of fire extinguishing, and even threatens the lives of firefighters.
