Abstract
The invention discloses an inner locked air valve device which comprises a ring-shaped valve casing, wherein the valve casing comprises a ring-shaped casing wall; an actuating shaft hole and a back shaft hole are formed in the casing wall; a back shaft lever is arranged in the back shaft hole; an actuating shaft lever is arranged in the actuating shaft hole; an air plate part is sleeved between the back shaft lever and the actuating shaft lever; the air plate part comprises a hollow cylindrical air plate sleeve and a disk-shaped air plate main body. According to the inner locked air valve device, based on the adoption of a first sleeve and a second sleeve, when the back shaft lever or the actuating shaft lever is broken, all that is needed for users is to replace the back shaft lever or the actuating shaft lever, the air plate main body does not needded to be replaced; as the embedded fit of locking ribs and locking grooves is adopted, the assembly is convenient, the fixation is firm and the possibility of looseness is low; the inner locked air valve device is compact in structure, convenient for assembly and disassembly and high in practicability.
Description
Technical field
The present invention relates to a kind of industrial ventilation equipment, or rather, is a kind of inner locking type wind valve device.
Background technique
Air-valve is a kind of common industrial ventilation equipment, is generally used in large-scale ventilation system.The aerofoil of existing air-valve and the as a whole foundry goods of aerofoil rotating shaft, change and maintenance all very bothers, and in addition, general aerofoil extremely difficulty is damaged, and integral replacing causes the wasting of resources.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of inner locking type wind valve device is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of inner locking type wind valve device, the valve casing that described inner locking type wind valve device comprises an annular, the shell wall that described valve casing comprises an annular, described shell wall is provided with a drive shaft hole and and supports axis hole, described support axis hole is provided with a support axostylus axostyle, described drive shaft hole is provided with a drive shaft rod, is socketed with an aerofoil portion between described support axostylus axostyle and drive shaft rod, the aerofoil sleeve cylindraceous that described aerofoil portion comprises a hollow and a discoid aerofoil main body.
As preferred embodiment of the present invention, the head of described drive shaft rod is provided with a pair of locking draw-in groove, described aerofoil sleeve comprises one first sleeve and one second sleeve, the diameter of the second described sleeve is greater than the diameter of the first described sleeve, the inwall of the first described sleeve is provided with a pair of locking rib, and described locking rib matches with described locking draw-in groove.
Inner locking type wind valve device of the present invention utilizes the first sleeve and the second sleeve in aerofoil sleeve, and in the time supporting axostylus axostyle or drive shaft rod and be damaged, user only needs to change and occurs to support axostylus axostyle or drive shaft rod, need not change aerofoil main body.Owing to adopting locking rib to coordinate with the embedded of locking draw-in groove, to install simply, fixation, is difficult for getting loose.This inner locking type wind valve device compact structure, easy disassembling, practical.
