Background
The dry powder fire extinguisher can extinguish general fire, and also can extinguish fire caused by burning oil, gas and the like. The dry powder fire extinguisher uses carbon dioxide gas or nitrogen gas as power to spray dry powder in a cylinder to extinguish fire. The cylinder body is made of high-quality carbon steel through a special process. The dry powder fire extinguisher has the advantages of simple structure, flexible operation, wide application, convenient use, low price and the like. The fire extinguisher mainly comprises a cylinder body, a bottle head valve, a spraying hose (nozzle) and the like, wherein the fire extinguishing agent is a sodium bicarbonate (ABC type is ammonium phosphate salt) fire extinguishing agent, the driving gas is carbon dioxide, the working pressure of the fire extinguisher is 1.5MPa at normal temperature, and the scrappage of the dry powder fire extinguisher is generally 8-12 years.
Therefore, the cylinder body of the conventional dry powder extinguishing device belongs to a high-pressure container, the cylinder body is constantly in a high-pressure state, the dry powder extinguishing device has risks in transportation, storage and standby, and meanwhile, the dry powder is in the high-pressure state, so that the dry powder extinguishing device is very easy to harden under long-time storage conditions, and the fire extinguishing effect is influenced.
Disclosure of Invention
In view of the above, the invention provides a suspended type dry powder self-service fire extinguishing device, which can realize the long-term storage of a dry powder fire extinguishing agent under normal pressure and complete high-pressure injection when a fire occurs.
A suspension type dry powder self-service fire extinguishing device comprises a gas generator, a connecting flange, a bottle body, an upper valve seat, a lower valve seat, a spray head and a diaphragm;
the upper end of the bottle body is connected with the gas generator through the connecting flange and then sealed, the gas outlet of the gas generator is communicated with the inner cavity of the bottle body, the opening at the lower end of the bottle body is connected with the upper valve seat, the lower part of the upper valve seat is connected with the lower valve seat, the upper valve seat and the lower valve seat are provided with corresponding through holes to form a spray channel of the dry powder extinguishing agent with the opening at the lower end of the bottle body, the membrane is fixed between the upper valve seat and the lower valve seat to seal the spray channel, the dry powder extinguishing agent is filled in the bottle body.
Furthermore, the upper valve seat is provided with a central through hole and a concentric threaded connecting hole, and the upper valve seat is fixedly connected with the bottle body through the threaded connecting hole.
Further, the upper valve seat and the lower valve seat are fixedly connected through bolts.
Furthermore, the nozzle is a shell with equal thickness consisting of a spherical head part and a cylindrical connecting part, the head part is uniformly provided with spray holes with equal diameters, the outer circumferential surface of the connecting part is provided with threads, and the nozzle is connected with the lower valve seat through the threads.
Has the advantages that:
the gas generator is arranged on the dry powder extinguishing device, and when the extinguishing device does not work, the dry powder extinguishing agent in the gas cylinder is in a normal pressure state, so that the hardening phenomenon of the dry powder extinguishing agent is effectively avoided, the risks brought by the conventional extinguishing device during transportation and storage are avoided, and the service life of the extinguishing device is prolonged.
