Problems solved by technology

[0003] However, in actual use, some fire dampers are not sensitive enough to close. For example, some fire dampers have not been fully closed when the fire has rushed through the exhaust duct, and most of the existing fire dampers need to be closed manually. The process is cumbersome

Abstract

The building exhaust duct fireproof valve comprises a fireproof valve body, an air inlet is formed in one side of the fireproof valve body, an air outlet is formed in the top end of the fireproof valve body, a first groove is formed in the top end of the fireproof valve body, and a thermal inductance water spraying mechanism is arranged in the first groove; the thermal inductance water spraying mechanism comprises a water tank, a water pump is arranged in the water tank, and a water inlet is formed in the input end of the water pump. Through a series of reasonable structure arrangements, the fireproof valve cover starts to slowly move when the connecting ends of the hot melting blocks are melted, the fireproof valve cover is completely closed when the connecting ends of the hot melting blocks are completely melted, compared with the prior art, the closing speed is higher, the situation that the fireproof valve cover cannot be closed due to external factors is avoided, and the fireproof valve cover is not damaged. And the device is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of fire dampers, more specifically, the invention relates to a fire damper for an air exhaust duct of a building. Background technique [0002] Most of the existing buildings are equipped with shared exhaust ducts, and the kitchens and toilets on each floor are connected to the shared exhaust ducts respectively. There is a check valve. At the same time, in order to prevent fires in other floors, the smoke and fire in the shared exhaust duct will be poured into the home room. The national standard also requires a fire damper to be installed in this part. When a fire breaks out in other rooms, close the valve to prevent The fire spread. [0003] However, in actual use, some fire dampers are not sensitive enough to close. For example, some fire dampers have not been fully closed when the fire has rushed through the exhaust duct, and most of the existing fire dampers need to be closed manually. The process is ...
