Abstract
The utility model discloses a smoke exhaust fireproof valve convenient to maintain, which relates to the technical field of fireproof valves and comprises a valve body, a connecting seat is arranged at the top end of the valve body, a valve plate is arranged in the center of the inside of the valve body, a fixing plate is vertically arranged in the middle of the valve plate, and four cross-shaped inserting rods are arranged on the side wall of a valve rod. Cross-shaped inserting grooves matched with the four cross-shaped inserting rods are formed in the positions, corresponding to the four cross-shaped inserting rods, of the fixing plate, and a fixing sleeve is detachably arranged on the front side of the fixing plate. The cross-shaped inserting rod is matched with the cross-shaped inserting groove, rapid inserting installation between the valve plate and the valve rod is achieved, the cross-shaped fixing groove in the fixing sleeve is further matched with the inserting rod in an inserting mode, and when the valve plate needs to be maintained or replaced, only the fixing bolt on the fixing sleeve needs to be screwed out, the fixing sleeve is taken down, and the valve plate can be assembled and disassembled. And the valve plate can be easily detached from the valve rod, the operation is simple and convenient, and the maintenance efficiency is greatly improved.
