Valve installation system for superfine dry powder fire extinguisher structure

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 a valve installation system of an ultrafine dry powder fire extinguisher structure. Background technique
