Puissant automatic fire-smothering unit

Abstract

The invention discloses a strong automatic fire extinguishing apparatus which comprises a pressure container, a spray nozzle and an alarm display unit; the pressure container is a double-chamber structure; the front end of a first chamber is connected with the spray nozzle in a seal way and the rear end of the first chamber is separated from a second chamber by a one-way pressure valve; the second chamber is provided with a charging valve; a second path of the spray nozzle is equipped with a signal sensor that can automatic detect the reduction of the internal pressure of the pressure container; a third path, a forth path and a fifth path of the spray nozzle are respectively equipped with a pressure display, a pressure relief device and a charging device. The fire extinguishing apparatus of the structure can not only cause a fire extinguishing agent in a cylindrical shell to be sprayed completely, but also can adjust the spraying speed of the fire extinguishing agent so as to cause the fire extinguishing agent to spread sufficiently; meanwhile, on the premise of guaranteeing use effect, the spray nozzle can be arranged towards any direction, thus being greatly convenient for the installation and use of the fire extinguishing apparatus; furthermore, the invention is characterized by compact and effective structure, humanization, automation, high safety, high fire extinguishing efficiency and being convenient for production.

Description

technical field [0001] The invention relates to an automatic fire extinguishing device, in particular to a fully submerged powerful automatic fire extinguishing device with automatic detection and explosion-proof functions. Background technique [0002] As the saying goes, "Water and fire are merciless." Once a fire occurs, if it cannot be extinguished in time, it will inevitably bring a great threat to people's lives and property safety. Therefore, it is very necessary to install automatic fire extinguishing devices in many key protection areas. Yes, for example, automobile engine just belongs to one of this key protection areas, and automatic fire extinguishing device is usually all equipped in existing automobile engine protection area, and the fire extinguishing device of automobile engine protection area of ​​prior art mainly adopts fire extinguishing agent cartridge The structure of the body plus the nozzle, the fire extinguishing agent cylinder is filled with fire ext...

AI Technical Summary

Problems solved by technology

[0004] The second purpose of the present invention is to overcome the deficiencies of the prior art and provide a powerful automatic fire extinguishing device, which can automatically detect the pressure drop in the fire extinguishing agent cylinder, and give an alarm when the pressure drops to a certain value, completely Solve several major safety hazards in the existing pressure storage type automatic fire extinguishing device, such as failure to start when there is a fire during long-term use, failure to effectively extinguish the fire in time after being subjected to high temperature in the fire field, and difficulty in pressure relief and refilling after-sales maintenance of the product; The whole structure is compact and effective, humanized, automatic, high in safety, high in fire extinguishing efficiency, and convenient for production.
