Gas release valve for fire fighting

Abstract

The invention provides a gas release valve for fire fighting. The gas release valve for fire fighting comprises a valve seat, an upper valve cover and a lower valve cover. The upper valve cover is fixed to the upper end of the valve seat, and the lower valve cover is fixed to the lower end of the valve seat. The gas release valve for fire fighting is characterized in that a brake device and a brake device opening mechanism are further arranged, an air inlet cavity is formed in the left side face of the valve seat, an air outlet cavity is formed in the right side face of the valve seat, the airinlet cavity and the air outlet cavity are separated by a partition plate, a connecting hole is formed in the partition plate, the brake device plugs the connecting hole, the brake device opening mechanism is arranged on the upper valve cover, and the brake device opening mechanism is connected with the brake device. The gas release valve for fire fighting has the beneficial effects that becausethe high pressure gas in fire fighting equipment is used for opening the valve, the force required for pressing a switch is effectively reduced; and the brake device opening mechanism greatly reducesthe number of parts, simplifies the structure, reduces the production cost, effectively reduces the probability of mechanical failures and prolongs the service life of the gas release valve for fire fighting.

Description

technical field [0001] The present invention relates to a fire-fighting equipment, more specifically to a gas release valve for fire-fighting equipment. Background technique [0002] For the gas release valves used in existing firefighting equipment, usually after the switch of the gas release valve is pressed, the valve needs to be opened through a transmission mechanism to release the compressed gas from the valve. [0003] Since the above-mentioned transmission mechanism of the gas release valve requires many components, the structure of the gas release valve is relatively complicated and the manufacturing cost is relatively high. And by pressing the power of the switch to open the valve, the user needs to apply enough power to open it, which is more laborious and difficult for people with weaker strength (such as children, the elderly, the weak, the sick and the disabled) to use. In addition, too many parts make the fire fighting equipment prone to more failures during ...

AI Technical Summary

Problems solved by technology

[0003] Because the transmission mechanism of the above-mentioned gas release valve needs to use many parts, the structure of the gas release valve is relatively complicated, and the manufacturing cost is relatively high.

And by pressing the force of the switch to open the valve, the user needs to apply enough force to open it, which is more laborious and difficult for people with weaker strength (such as children, old, weak, sick and disabled people) to use

In addition, too many parts cause fire equipment to be prone to more failures during storage, and if a failure occurs in the event of a fire, it will cause serious consequences
