Abstract
The utility model relates to an anti-rotation device of a valve rod of a stop valve. The anti-rotation device of the valve rod of the stop valve can effectively prevent the valve rod from rotating. The anti-rotation device comprises a valve deck with inverted ribs, the valve rod, inner hexagon screws and a set screw, and is characterized in that a clamp plate is arranged on the valve deck and comprises a front clamp plate body and a rear clamp plate body, the clamp plate and the valve rod are fixed together through the set screw, the inner hexagon screw is arranged in the front clamp plate body, and another inner hexagon screw is arranged in the rear clamp plate body.
Description
Technical field
The utility model relates to a kind of valve technology, and what be specifically related to is a kind of stop valve valve rod anti-rotation device.
Background technique
Stop valve in the market in use, the phenomenon that valve rod rotates easily occurs, and main cause is in stop valve, not to be provided with effectively to prevent the device that valve rod is not moved, and causes stop valve short working life.
The model utility content
The purpose of this utility model is in order to provide a kind of stop valve valve rod anti-rotation device that can effectively prevent that valve rod from rotating.
For realizing the purpose of this utility model, the utility model adopts following technological scheme: stop valve valve rod anti-rotation device comprises and is provided with the valve gap of swinging to muscle, valve rod, socket head screw, Cock screw, is characterized in that, described valve gap is provided with clamping plate, described clamping plate are provided with front plate and rear plate, described clamping plate and described valve rod are fixed together by described Cock screw, in described front plate, are provided with socket head screw, in described rear plate, are provided with socket head screw.
The beneficial effects of the utility model: by front plate and rear plate, being equipped with socket head screw, allow and produce screwing force between front plate, rear plate, socket head screw three, add making a concerted effort of producing between clamping plate, valve rod, Cock screw three, can effectively prevent that valve rod from rotating.
The accompanying drawing explanation
The structural representation that Fig. 1 is model utility.
Embodiment
Below in conjunction with accompanying drawing, further illustrate:
As described in Figure 1, the utility model comprises and is provided with the valve gap 1 of swinging to muscle, valve rod 5, socket head screw 3,8, Cock screw 4, it is characterized in that, described valve gap 1 is provided with clamping plate 7, and described clamping plate 7 are provided with front plate 2 and rear plate 6, and described clamping plate 7 are fixed together by described Cock screw 4 with described valve rod 5, be provided with socket head screw 3 in described front plate 2, in described rear plate 6, be provided with socket head screw 8.
Working principle: described front plate 2 and rear plate 6, by the screwing force of described socket head screw 3,8, hold described valve rod 5 tightly, add described Cock screw 4 by described front plate 2, fixing described valve rod 5, both make a concerted effort prevent that described valve rod 5 from rotating.
The purpose of this utility model, feature and advantage, in connection with embodiment, are further described with reference to accompanying drawing.To contribute to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection domain of the present utility model.
