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 through a universal shaft, a non-through groove is formed on the universal shaft, the groove is V-shaped, 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-retaining bearing respectively, two pressure plates are mounted at the two ends of the blades respectively, and one of the pressure plates corresponds in position to the V-shaped groove of the universal shaft. The vent valve further comprises a motor connected with one end of the universal shaft, and a rotating rod fixedly connected with the other end of the universal shaft. The vent valve has the advantages of simple structure and convenient processing, and therefore can effectively reduce air leakage, thereby saving energy sources and facilitating environmental protection. Moreover, the vent valve can ensure more flexible rotation of the universal shaft and the oil-retaining bearing and firmer fixation of the rotating rod with the shaft, thereby reducing noise.

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 for reach the purpose of not welding all adopt the V-type groove the axle, but since valve shaft pass valve body, make the axle the V-type groove seriously leak out, waste energy, under the high situation of wind speed, also can produce noise, particularly be used in the environment of toxic gas.

Summary of the invention

The purpose of this utility model provides a kind of Ventilating valve, does not get used to logical V-type groove by offer one on common shaft, can effectively avoid the shortcoming that prior art seriously leaks out and axle and oiliness bearing be rotated more flexibly and swing arm is fixed more firm with axle.

The purpose of this utility model is achieved in that a kind of Ventilating valve, comprises a housing and some blades, and described blade pass is crossed a common shaft and is rotatably installed on the housing, has a groove that does not connect on this common shaft.

Preferably, described groove is V-shaped.

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

Preferably, a pressing plate respectively is equipped with at the two ends of described blade, and wherein the position of a pressing plate is corresponding with the V-type groove of common shaft.

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; Save the energy thereby can effectively reduce inleakage like this, help environmental protection; And make common shaft and oiliness bearing rotate more flexibly and swing arm and axle are fixed more firmly, reduced noise.

Among the figure, 1 blade, 2 pressing plates, 3 bracing struts, 4 oiliness bearings, 5 common shafts, 6 swing arms, 7 housings, 8 motors.

The specific embodiment

As Fig. 1, shown in 2,3, the utility model comprises a housing 7 and some blades 1, and in the present embodiment, the quantity of blade 1 is two.Blade 1 is rotatably installed on the housing 7 by a common shaft 5, has a groove that does not connect on this common shaft 5.In the present embodiment, this groove is V-type groove (Fig. 4,5).

As shown in Figure 3, also comprise a bracing strut 3 and oiliness bearing 4.Be set in the two ends of common shaft 5 and between blade 1 and housing 7.A pressing plate 2 respectively is equipped with at the two ends of blade 1, and wherein the position of a pressing plate 2 is corresponding with the V-type groove of common shaft 5.Wherein, open V-shaped groove, blade 1 and pressing plate 2 and common shaft 5 are fixed together firmly, do not open V-shaped groove, make air-flow not spill housing, reduce inleakage, energy savings by V-shaped groove and pass a section of housing 7 with fixing one section of pressing plate 2.

As Fig. 1, shown in 3, also comprise a motor 8, be connected with common shaft 5, drive common shaft 5 and rotate.And a swing arm 6, fixedly connected with the other end of common shaft 5.

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.
