The invention discloses a fireproof valve with the smoke dust filtering structure. The valve comprises a valve body, supports are welded to the inner walls of the valve body, filtering boxes are arranged in the supports, sliding blocks are welded to the upper ends and the lower ends of the filtering boxes, the outer sides of the four sets of sliding blocks are sleeved with sliding grooves, and the sliding grooves are welded to the inner wall of the valve body; and spring grooves are embedded at the periphery of the filtering boxes, and springs are arranged in the four sets of spring grooves. A handle drives the filtering boxes to move, the filtering boxes move in the sliding grooves through the sliding blocks, the filtering boxes are taken out of the valve body, the filtering boxes are conveniently replaced, meanwhile, a pressing plate is pulled, the pressing plate drives an inserting rod to move, a protruding block at the tail end of the inserting rod is moved out of a groove formed in the inner wall of a sleeve, and filtering of a filtering layer is facilitated.
Description
technical field [0001] The invention relates to the technical field of fire dampers, in particular to a fire damper with a smoke filter structure. Background technique [0002] When the fire damper is in use, the fan blades are closed, and the closed fan blades may create gaps, and the smoke and dust will move out of the gaps generated by the fan blades, and move to other places through the ventilation pipe, causing smoke and dust to be generated elsewhere, and now the market There is a kind of fire damper with smoke filter. When the filter layer of smoke filter is generally installed inside the fire damper, it is troublesome to replace the filter layer. Generally, the filter layer will not be replaced after the fire damper is used, so that the filter layer After being used again, the effect is not good, so there is an urgent need for a fire damper with a smoke filter structure to solve the above problems. Contents of the invention [0003] The object of the present inven...
