Abstract
The utility model is related to flange form damping check valve, including valve body, valve rod, valve plate and guiding balancing stand, the valve rod is located in the valve body, and the valve rod runs through the central shaft of the valve plate, one end of the valve body is connected with guiding balancing stand, and valve plate is located at the upper end for being oriented to balancing stand.The utility model close to the side for being oriented to balancing stand in valve plate by setting valve plate, and the line with rubber of valve plate is difficult for drop-off, and preferably, the outer surface of valve plate is difficult to get rusty sealing due to there is line with rubber, realizes that its internal valve plate sealing is strong, it is to avoid the phenomenon of water seepage occur.
Description
Technical field
The utility model is related to the technical field of valve, especially flange form damping check valve.
Background technology
Damping check valve is mainly used on the pipeline of medium one-way flow, only allows medium to be flowed to a direction, to prevent
Only occur the parts such as accident, including valve body, guiding balancing stand, valve rod, back-moving spring, valve plate, its main operational principle is valve plate
Along the check-valves of valve stem slides, damping check valve is applied to be installed on various horizontal pipes.
Traditional damping check valve uses simple valve plate, and other sealing structures are not set, its sealing property compared with
Difference, the Seepage for water easily occur.
Therefore, it is necessary to design a kind of damping check valve, realize that its internal valve plate sealing is strong, it is to avoid water seepage occur
Phenomenon.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and there is provided flange form damping check valve.
To achieve the above object, the utility model uses following technical scheme：Flange form damping check valve, including valve body,
Valve rod, valve plate and guiding balancing stand, the valve rod are located in the valve body, and the valve rod runs through the central shaft of the valve plate,
One end of the valve body is connected with guiding balancing stand, and the valve plate is located at the upper end of the guiding balancing stand.
Its further technical scheme is：The valve plate is full lining glue valve plate, and the valve plate includes cast steel valve plate and is located at
The line with rubber composition of the outer surface of the cast steel valve plate.
Its further technical scheme is：Back-moving spring is provided between the valve rod and the valve plate.
Its further technical scheme is：The lower end of the valve rod is connected with the guiding balancing stand by gland bolt.
Its further technical scheme is：Sealing ring is provided between the guiding balancing stand and the valve body.
The beneficial effect of the utility model compared with prior art is：Flange form damping check valve of the present utility model, leads to
Cross in valve plate close to the side setting valve plate for being oriented to balancing stand, the line with rubber of valve plate is difficult for drop-off, and sealing is preferable, the appearance of valve plate
Face is difficult to get rusty due to there is line with rubber, realizes that its internal valve plate sealing is strong, it is to avoid the phenomenon of water seepage occur.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the cutting structural representation for the flange form damping check valve that the present embodiment is provided.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Realization of the present utility model is described in detail below in conjunction with specific embodiment.
Reference picture 1, the preferred embodiment provided for the utility model.
The flange form damping check valve that the present embodiment is provided, including valve body 1, valve rod 2, valve plate and guiding balancing stand 6, valve
Bar 2 is located in valve body 1, and valve rod 2 runs through the central shaft of valve plate, and one end of valve body 1 is connected with guiding balancing stand 6, the valve plate position
In the upper end of the guiding balancing stand 6.
Further, the valve plate is full lining glue valve plate, and the valve plate includes cast steel valve plate 3 and positioned at the cast steel
The line with rubber 4 of the outer surface of valve plate 3 is constituted.
Further, back-moving spring 5 is provided between valve rod 2 and valve plate, when current are entered in valve body 1, valve plate is beaten
Open, back-moving spring 5 is compressed, when current stop entering in valve body 1, valve plate is closed, and back-moving spring 5 resets；Work as water (flow) direction
When in into valve body 1, valve plate in the presence of current, towards close to be oriented to balancing stand 6 direction movement, compress valve plate, current without
Method flows out, and plays a part of non-return, line with rubber 4 can cause the seal degree being oriented between balancing stand 6 and valve plate to improve, so that more
The good effect that ensure that non-return.
In addition, the lower end of valve rod 2 is connected with the guiding balancing stand 6 by gland bolt 7.
Sealing ring is provided with addition, being oriented between balancing stand 6 and the valve body 1, is served sealedly.
Further, the both sides of valve body 1 are respectively equipped with mounting hole, when installing valve body 1, are installed by flange.
Above-mentioned flange form damping check valve, by setting valve plate close to the side for being oriented to balancing stand 6 in valve plate, valve plate
Line with rubber 4 is difficult for drop-off, and preferably, the outer surface of valve plate is difficult to get rusty sealing due to there is line with rubber 4, realizes that its internal valve plate is close
Feng Xingqiang, it is to avoid the phenomenon of water seepage occur.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
