RAPID OPENING PRESSURE REGULATING VALVE, FIRE EXTINGUISHER USING IT, HIGH PRESSURE GAS CYLINDER DEVICE, AND FLUID QUICK SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a compact rapid opening pressure regulating valve capable of improving flow rate characteristic and to provide a fire extinguisher using it, a high pressure gas cylinder device, and a fluid quick supply device. SOLUTION: When assembling the rapid opening pressure regulating valve, a valve element member main body 22 is inserted into a main body 1, and a valve element 21 is inserted through an inlet 11a of an inlet nozzle part 11 and is inserted into and fixed to a lower end of the valve element part main body 22. To fix the valve element 21 and the valve element member main body 22, for example, an inner peripheral face of the valve element 21 and an outer peripheral face at a lower end of the valve element member main body 22 corresponding to it are threaded and a lower end of the valve element part main body 22 is screwed into the valve element 21 and is fixed. Since a valve seat 13 is provided in the main body 1 and the valve element member main body 22 and the valve element 21 are inserted from an upper end side of the main body 1 and through the inlet 11a of the main body 1 to mount them by nipping the valve seat 13 in this way, a conventional intermediate barrel becomes unnecessary and the number of members is reduced to miniaturize the rapid opening pressure regulating valve.
