Abstract

The invention provides an ultra-fine dry powder fire extinguisher structure and a valve mounting system, belongs to the technical field of fire extinguishers, relates to a fire extinguisher valve, and solves the problems of poor valve sealing effect, inconvenience in use and operation, unsmooth injection and difficult disassembly in the prior art. The ultra-fine dry powder fire extinguisher structure comprises a tank body and a valve, wherein the valve comprises an upper valve seat, a spool assembly, a reset spring and a lower valve seat; the valve mounting system comprises an assembly table; big-end-up stepped holes allowing the upper valve seat to be placed are formed in the assembly table; an insertion rod which can be inserted into an air outlet of the valve is arranged on the assembly table; a rotary head corresponding to the passage in the pipe of the lower valve seat is arranged below the assembly table; the rotary head is provided with a square end matched with a square cavity of the passage in the pipe of the lower valve seat; and the rotary head is controlled by a telescopic mechanism to expand and contract vertically. The ultra-fine dry powder fire extinguisher structure disclosed by the invention is simple in the structure, good in sealing performance, easy to operate and quick in spraying; and the valve mounting system disclosed by the invention can be used for quickly assembling the valve, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishers, and relates to a fire extinguisher valve, in particular to an ultrafine dry powder fire extinguisher structure and a valve installation system. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals or fire extinguishing gas and solid are placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients. They are specially designed for different types of fires. Fire extinguishers have various types, functions and use environments. different. At present, the mainstream fire extinguishers basically open the fire extinguisher by pressing the valve, so that the fire extinguishing substance (such as dry powder, special clean gas for fire extinguishing...
