Gas extinguishing agent container valve

Abstract

The invention provides a gas extinguishing agent container valve. An upper end opening of a valve body of the gas extinguishing agent container valve is communicated with a gas collecting pipe, a lower end opening of the valve body is connected with an extinguishing agent cylinder, and an inner sealing cap in the valve body is used for blocking off communication between the upper end opening and the lower end opening. A first piston is arranged in a start connector in the outer sidewall of the valve body, a first push rod is arranged on one side of the first piston and extends into a first through hole, and a blasting cartridge is arranged between the first piston and a pressing cap on the start connector. After being ignited, the blasting cartridge releases high-pressure gas to push the first piston and the first push rod to strike the inner sealing cap broken, then the extinguishing agent cylinder can be communicated with the gas collecting pipe to start an extinguisher to extinguish fire, and accordingly a start mode is safe and reliable. The valve body is provided with a pressure measuring connector and a pressure gauge seat connected with the pressure measuring connector, the pressure gauge seat can enable a pressure gauge to be communicated with the pressure measuring connector when the pressure gauge is connected into the pressure gauge seat, and the pressure gauge is automatically isolated from the pressure measuring connector when being demounted, so that to bleed the extinguishing agent cylinder when the pressure gauge is replaced is not needed.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a gas fire extinguishing agent container valve. Background technique [0002] There are many types of gas fire extinguishing agent container valves, which are divided into electric automatic start, electric manual start and mechanical emergency start according to the starting method; according to the sealing method, it is divided into diaphragm seal type, piston seal type, etc.; all kinds of container valves are more or less There are such and such problems, such as air leakage in the sealing part and so on. There is also a diaphragm-sealed container valve. Due to the influence of the performance of the spring that drives the puncture needle to puncture the diaphragm, and the influence of the starting gas pressure, diaphragm performance and product production quality, sometimes the diaphragm is difficult to be punctured in time. , thus affecting the normal ejection of the ...

AI Technical Summary

Problems solved by technology

There is also a diaphragm-sealed container valve. Due to the influence of the performance of the spring that drives the puncture needle to puncture the diaphragm, and the influence of the starting gas pressure, diaphragm performance and product production quality, sometimes the diaphragm is difficult to be punctured in time. , thus affecting the normal spraying of the gas fire extinguishing agent, and when the pressure gauge is damaged, the pressure gauge cannot be replaced in time. Only when all the fire extinguishing agent in the fire extinguishing agent storage cylinder is released can the pressure gauge be replaced
