Abstract

The invention discloses a thermal sensitive fire control angle valve. The thermal sensitive fire control angle valve comprises a valve body, wherein an end cap is arranged at one end of the valve body; a water inlet valve, a water outlet valve, a pressure regulating valve and a thermal sensitive inductive head are installed on the end cap; a baffle and a flange connected with a tap water net are fixed on the other end of the valve body; a water outlet flange is arranged on the side surface of the valve body; a valve core which can axially slide is arranged on a cavity of the valve body and a hollow body, a water inlet is formed in one end surface, facing the end cap of the valve body of the valve core, the other end surface of the valve body is sealed, and two ends of the valve core are respectively sleeved with a plurality of elastic sealing rings; sections of the plurality of elastic sealing rings are U-shaped, U-shaped openings face a shaft center of the valve core, and through-flow rings are clamped in U-shaped cavities; and holes communicated with the valve cavity are evenly formed in the through-flow rings. The thermal sensitive fire control angle valve is free of electric power, can achieve that a water screen door is free of leaking water when the tap water net is under high pressure, and can push the valve core to move and start quickly to form the water screen door when the tap water net is under low pressure, and consequently, air flowing between the indoor and the outdoor can be separated, convenience can be brought for escaping of trapped persons and moving in-and-out of firefighters, and thereby being beneficial to controlling and eliminating fire danger.

Description

technical field

[0001] The invention relates to a heat-sensitive fire-fighting angle valve, which belongs to a fire-fighting device. Background technique

[0002] The main function of the fire door is to block the connection between the indoor (fire zone) fire source and the outdoor air (oxygen) and prevent the flame from escaping. It can meet the fire hazards of different dangerous buildings and structures, such as; hotels, warehouses, hospitals , Shopping malls, entertainment venues, office buildings, theaters and other places of fire demand.

[0003] Domestic fire doors are mainly rigid fire doors. Its disadvantage is that when a fire breaks out, after the rigid fire door is closed, the trapped people cannot escape, and the firefighters cannot enter. Although it can control the expansion of fire danger, it may cause casualties, and also cause inconvenience to firefighters in and out, and delay the fire fighting time. The technology of using fire water curtain door in...
