Description

TECHNICAL FIELD

[0001] The utility model relates to a fire-fighting pipe network exhaust device and belongs to the fire-fighting field. BACKGROUND

[0002] Gases occupy a certain space in the fire-fighting pipe network, which hinders the smooth flow of fire-fighting water. In the case of fire emergency, this can cause water to be unable to reach the fire extinguishing position quickly, delaying the fire extinguishing opportunity. At the same time, the presence of gases can interfere with the stability of the pressure in the pipe network, so that the fire-fighting water cannot reach the required pressure for fire extinguishing, reducing the fire extinguishing effect. Manual exhaust valves are usually installed at the end or high point of the pipe network. When exhausting, the operator manually opens the exhaust valve to let the gases out. During the operation process of manually opening the fire-fighting pipe network exhaust valve, due to the high pressure existing in the pipe network, the air discharged from the exhaust valve is not simply gaseous, but is sprayed out together with part of the water. These mixed media have extremely fast flow rate and strong impact force under the action of high pressure. Once splashed on the body of personnel, it can cause injuries such as scratches and bruises; if splashed on surrounding electrical equipment, precision instruments, etc., it can cause equipment short circuit, damage, and affect the normal operation. This potential risk poses a great threat to the safety of on-site operators and equipment, and there is a security risk that cannot be ignored. SUMMARY
