Abstract

The utility model discloses a vent valve comprising an outer frame and a plurality of blades, wherein, the blades are rotationally mounted on the outer frame, two inclinations are arranged respectively at the two ends of the blades adjacent to the outer frame, the blades are rotationally connected with the outer frame through a universal shaft, two ends of the universal shaft are arranged between the blades and the outer frame, and are further sleeved with a shaft bracket and an oil retraining bearing, and two pressure plates are mounted at the two ends of the blades respectively. The vent valve further comprises a motor connected with the one end of the universal shaft, and a rotating rod fixedly connected with the other end of the universal shaft. By processing certain inclinations at the two ends of the blades, the distance from the blades to the outer frame is reduced to zero, thereby not only reducing air leakage, but also preventing the blades from colliding with the valve body. Moreover, the utility model is energy-efficient and favorable for environmental protection.

Description

Ventilating valve

Technical field

The utility model relates to mechanical field, relates in particular to a kind of valve mechanism that is used to ventilate.

Background technology

At present, general Ventilating valve all is a rectangle, and this shape is easy to generate following problem: if blade and valve body gap are too small, cause the collision of blade and valve body easily, cause valve normally to close; Exceed standard if gap between two ends amplifies to cause seriously to leak out, waste energy.

Summary of the invention

The purpose of this utility model provides a kind of Ventilating valve, makes blade and outer frame length reach zero distance, and so not only reduce inleakage, but also reached blade and valve body does not collide function, and the saving energy.

The purpose of this utility model is achieved in that a kind of Ventilating valve, comprises a housing and some blades, and described blade rotation is installed on the housing; Blade respectively is provided with a gradient near the two ends of housing.

Preferably, described blade pass is crossed a common shaft and housing is rotationally connected, and each a sheathed bracing strut and oiliness bearing are gone back in the two ends of common shaft between blade and housing.

Preferably, a pressing plate respectively is equipped with at the two ends of described blade.

Preferably, also comprise a motor, be connected with an end of common shaft; One swing arm is fixedlyed connected with the other end of common shaft.

The utility model makes it compared with prior art owing to adopted above technical scheme, and have the following advantages and good effect: it is simple in structure, and is easy to process; Process certain gradient by two ends, make blade and outer frame length reach zero distance, so not only reduced inleakage, but also reached blade and valve body does not collide function blade, and the saving energy, help environmental protection.

Description of drawings

Fig. 1 is a Ventilating valve schematic diagram of the present utility model.

Fig. 2 is that the A-A of Fig. 2 is to schematic diagram.

Fig. 3 is that the B of Fig. 2 is to schematic diagram.

Fig. 4 is the C part enlarged diagram of Fig. 3.

Among the figure, 1 is that blade, 2 is swing arm for motor, 8 for bracing strut, 5 housings, 6 common shafts, 7 for oiliness bearing, 4 for pressing plate, 3.

The specific embodiment

As Fig. 1, shown in 2,3, the utility model comprises a housing 5 and some blades 1.Blade 1 is rotationally connected with housing 5 by a common shaft 6, and each a sheathed bracing strut 4 and oiliness bearing 3 (Fig. 4) are gone back in the two ends of common shaft 6 between blade 1 and housing 5.Blade 1 respectively is provided with a gradient near the two ends of housing 5.

As Fig. 2, shown in 3, a pressing plate 2 also respectively is equipped with at the two ends of blade 1.Also comprise a motor 7, be connected, drive common shaft 6 and rotate with common shaft 6.And a swing arm 8, fixedly connected with the other end of common shaft 6.

During assembling, certain gradient is at first gone out through special dies in the two ends of blade 1, then oiliness bearing 3 is pushed up at blade 1 two ends, make blade 1 and bracing strut 4 reach zero distance, the two ends gradient of blade 1 can not run into bracing strut again when rotating like this, valve promptly can be not stuck like this, reduced inleakage again.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
