Abstract
The utility model discloses a check valve structure with an elastic gasbag. The check valve structure comprises a valve body, wherein a valve plate is rotatably mounted in the valve body; the hollow elastic gasbag is connected between the valve plate and the inner wall of the top of the valve body. The valve plate is pushed and pressed by inflating the elastic gasbag, the bottom end of the valve plate presses a press table, and the problem that a gap causes incomplete turn-off is avoided.
Description
Technical field
The utility model relates to field of check valves, is specially a kind of check valve structure with elastic bag.
Background technique
Safety check is a kind of conventional valve class device, and its principle is to rely on the strength of media flow to realize keying, to prevent the refluence of medium, is mainly used on the pipeline of medium one-way flow.In prior art safety check, the general valve plate by one-way rotation is realized sealing, and the safety check valve plate of this structure easily leaves space in the time turn-offing, and causes turn-offing incomplete problem.
Model utility content
The purpose of this utility model is to provide a kind of check valve structure with elastic bag, has to solve prior art safety check the incomplete problem of turn-offing.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of check valve structure with elastic bag, in including, there is the valve body of cavity, it is characterized in that: valve body top inner wall left side is provided with mounting platform, valve body bottom interior wall right side is provided with presents a theatrical performance as the last item on a programme, the tilted valve plate that is provided with shape and valve body cross-sections match of valve body, described valve plate top left hand is rotatably installed on mounting platform, valve plate bottom left side shape and the form fit of presenting a theatrical performance as the last item on a programme, and left side, valve plate bottom is pressed on the upper formation sealing of presenting a theatrical performance as the last item on a programme, between described valve plate upper right and valve body top inner wall, be connected with the elastic bag of hollow, valve body top is provided with the pipe joint being communicated in elastic bag.
Described a kind of check valve structure with elastic bag, is characterized in that: described elastic bag is triangle body shape.
In the utility model, pressure elasticity air bag in the time that valve plate is opened, discharges gas in elastic bag, in the time that valve plate is closed, can realize valve plate pushing by inflation in elastic bag, valve plate bottom is pressed on and present a theatrical performance as the last item on a programme above, avoid occurring that space causes turn-offing incomplete problem.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
