Container valve for gas extinguishing agent steel cylinder

Abstract

The invention discloses a container valve for a gas extinguishing agent steel cylinder. The container valve comprises a valve body, a connector, a sealing cap and a handle, wherein the connector, the sealing cap and the handle are connected to the valve body; the upper and lower parts of the valve body are hollow, and the connector is mounted at the top of the valve body; a first circular cavity and a second circular cavity are convexly arranged on the side surface of the valve body, and an inner cavity is sealed by the sealing cap; a piston ejector rod opposite to the sealing cap is arranged in the first circular cavity, and the exterior of the first circular cavity is connected with a pressing cap; a needle valve element is arranged in the second circular cavity, and the exterior of the second circular cavity is connected with the handle through the needle valve element; a breaking groove is formed in the sealing cap; a ring groove is formed downwards from the top surface of the valve body, a first through hole is formed from the bottom surface in an upward bending manner, the needle valve element is opposite to the first through hole, the first through hole is communicated with the second circular cavity, and the second circular cavity is communicated with the ring groove through a second through hole; a third through hole is formed in the first circular cavity and communicates the ring groove with the first circular cavity. The container valve for the gas extinguishing agent steel cylinder is started pneumatically or manually, and the piston ejector rod is pushed to break the sealing cap, so that a gas extinguishing agent is sprayed to reach a part to be extinguished, and the container valve is convenient and safe to operate.

Description

technical field [0001] The invention relates to a container valve placed on a gas fire extinguishing agent cylinder for controlling the release of fire extinguishing agent. Background technique [0002] There are many types of container valves for gas fire extinguishing agent cylinders. According to the starting mode, they are divided into electric automatic start, electric manual start and mechanical emergency start, etc.; according to the sealing method, they are divided into diaphragm seal type, piston seal type, etc.; Or at least there are such and other problems, such as air leakage in the sealing part. For electric starters, due to the short circuit of other external parts, the electric starter part is mistakenly connected to a current greater than the starting current, causing the electric starter to malfunction, and there is also the influence of static electricity, which leads to the malfunction of the starter container valve and the malfunction of the fire extingui...

AI Technical Summary

Problems solved by technology

For electric starters, due to the short circuit of other external parts, the electric starter part is mistakenly connected to a current greater than the starting current, causing the electric starter to malfunction, and there is also the influence of static electricity, which leads to the malfunction of the starter container valve and the malfunction of the fire extinguishing agent cylinder. spray incident etc.

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 gas fire extinguishing agent
