Abstract

The invention relates to the technical field of smoke exhaust type fireproof valves, in particular to a smoke exhaust type fireproof valve with a filtering mechanism, which comprises a device main body, the device main body comprises a fireproof valve main body, the bottom end of the fireproof valve main body is fixedly connected with a base, the fireproof valve main body is internally provided with a filtering device, and the filtering device comprises a filtering plate. Filter plates are fixedly connected into the front side and the rear side of the fireproof valve body correspondingly, first open grooves are formed in the upper portion and the lower portion of the inner wall of the front side and the inner wall of the rear side of the fireproof valve body correspondingly, insertion rods are inserted into the eight first open grooves correspondingly, pull rings are fixedly connected to the outer sides of the insertion rods correspondingly, and fixing blocks are fixedly connected to the inner sides of the insertion rods correspondingly. And the fixed blocks are inserted into holes formed in the inner walls of the upper and lower sides of the two sides of the filter plate. By means of the device, impurities in smoke can be filtered out through the filter plate in the using period of the fireproof valve body, and the practicability and protection performance of the device are greatly improved.

Description

technical field [0001] The invention relates to the technical field of a smoke exhaust type fire damper, in particular to a smoke exhaust type fire damper with a filtering mechanism. Background technique [0002] The fire damper is a kind of temperature control of memory fusion alloy, which is closed by the action of gravity and spring mechanism. When the temperature of the smoke reaches 280 degrees, the evacuation of people has been basically completed, and the fire is present in the smoke. , the valve is automatically closed to avoid the spread of fire. The smoke exhaust valve is generally installed on the pipe of the smoke exhaust system of high-rise buildings and underground buildings. Therefore, the smoke exhaust fire damper has been continuously developed and innovated, and it has basically met people's needs. But there are still some problems. [0003] During the use of the existing smoke exhaust fire damper, because the smoke is ignited, some impurities will remain ...
