Gas release valves for nitrogen fire extinguishing systems

Abstract

The invention relates to a gas valve, and discloses a gas release valve of a nitrogen fire extinguishing system. The gas release valve comprises two high-pressure control valves, a release controller, a high-pressure pneumatic head, a bracket, a connection sleeve, a valve shaft, a filler gland, a filler, a valve cover, a sealing ring, a valve body, a valve core and a hand-steering mechanism, wherein the two high-pressure valves are respectively connected with a left cylinder and a right cylinder of the high-pressure pneumatic head; the high-pressure pneumatic head is respectively connected with the bracket and the connection sleeve; the connection sleeve is connected with the valve shaft; the valve shaft is connected with the valve core; the valve body and the valve cover are fixed outside the valve core through bolts and screw caps; the filler is positioned at the periphery of the valve shaft; the filler gland is pressed on the filler; the hand-steering mechanism is connected with the valve shaft; and the release controller is respectively connected with the two high-pressure control valves. The gas release valve is compact in mechanism, sensitive in operation, high in starting speed, high in reliability, low in pressure drop loss, large in valve capacity and convenient to maintain.

Description

technical field [0001] The invention relates to a gas valve. Specifically relates to a gas release valve of a nitrogen fire extinguishing system. Background technique [0002] At present, the gas release valves used for fire fighting are directly opened or closed during work. Due to the pressure change of the gas or the damage of the valve, etc., it may not be able to open or close, and it cannot be safe and reliable. The 2nd, the mode of opening or closing of existing gas release valve is single, as manual, or electric. The 3rd, existing gas release valve mechanism is more complicated, and maintenance is inconvenient. Contents of the invention [0003] The object of the present invention is to provide a gas release valve for a nitrogen fire extinguishing system with compact structure, sensitive action, fast opening speed, high reliability, small pressure drop loss, large generating capacity and convenient maintenance. [0004] In order to achieve the above object, the...

AI Technical Summary

Problems solved by technology

Due to changes in gas pressure or damage to the valve, it may not be able to open or close, and cannot be safe and reliable.

The second is that the existing gas release valve is opened or closed in a single way, such as manual or electric

The third is that the existing gas release valve mechanism is relatively complicated and inconvenient to maintain
