Abstract
The utility model discloses a check valve structure, which comprises a valve body, wherein the bottom of the valve body is provided with a groove body which is communicated with the interior of the valve body, the left and right side walls of the groove body respectively extend into a valve body, the top of the valve body is vertically connected with a retaining plate, the retaining plate extends into the space between the left and right side walls of the groove body, the left and right sides of the retaining plate are respectively provided with a stop seat, the left and right side walls of the groove body are respectively and rotationally provided with a valve plate, the upper part of the plate end of a valve plate at the left side wall of the groove body is abutted against the bottom of the stop seat at the left side of the retaining plate, and the lower part of the plate end of the valve plate at the right side wall of the groove body is abutted against the top of the stop seat at the right side of the retaining plate. The check valve structure has the advantages that under the condition of long-time use, the check function on a small amount of fluid medium is realized, and the property of the check valve is improved.
Description
Technical field
The utility model relates to field of check valves, is specially a kind of check valve structure.
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.After prior art safety check length service time, opening/closing mechanism sealing reduces, and easily has the problem refluxing.
Model utility content
The purpose of this utility model is to provide a kind of check valve structure, to solve the prior art safety check long problem that is prone to backflow service time
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of check valve structure, include valve body, a valve body left side, right-hand member is set to respectively valve port, it is characterized in that: described valve body bottom is provided with and the cell body being communicated with in valve body, before cell body, before rear sidewall and valve body, rear sidewall flushes and connects as one, a cell body left side, right side wall stretches into respectively in valve body, described valve body top is vertically connected with baffle plate, before baffle plate, before rear side and valve body, rear sidewall connects as one, described baffle plate stretches into a cell body left side, between right side wall, a baffle plate left side, right side is respectively arranged with the stop bit seat mutually staggering position, a described cell body left side, on right side wall, be rotatablely equipped with respectively horizontally disposed valve plate, wherein the valve plate plate end top on cell body left side wall is supported in stop bit seat bottom, baffle plate left side, valve plate plate end bottom on cell body right side wall is supported at stop bit seat top, baffle plate right side.
Described a kind of check valve structure, is characterized in that: described cell body left side wall stop bit seat bottom, right side wall stop bit seat top are respectively arranged with sealing layer.
In the utility model, utilize both sides valve plate to coordinate with stop bit seat the function that realizes non-return, flowing medium flows into valve body from left end valve port, after being rotated, cell body left side valve plate enters cell body, after making again cell body right side valve plate rotate, flow out from right-hand member valve port, the cell body arranging plays buffer function, while backflow due to a small amount of flowing medium of the poor appearance of sealing with corresponding stop bit seat due to right side valve plate, first enter in cell body, and a small amount of flowing medium cannot make left side valve plate rotate, therefore can play the function of auxiliary non-return.The utility model in long situation, still can play the function of non-return between in use for a small amount of flowing medium, improved the performance of safety check.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of check valve structure, include valve body 1, valve body 1 left side, right-hand member is set to respectively valve port 2, valve body 1 bottom is provided with and the interior cell body being communicated with 3 of valve body 1, before cell body 3, before rear sidewall and valve body 1, rear sidewall flushes and connects as one, cell body 3 left sides, right side wall stretches into respectively in valve body 1, valve body 1 top is vertically connected with baffle plate 4, before baffle plate 4, before rear side and valve body 1, rear sidewall connects as one, baffle plate 4 stretches into cell body 3 left sides, between right side wall, baffle plate 4 left sides, right side is respectively arranged with the stop bit seat 5 mutually staggering position, cell body 3 left sides, on right side wall, be rotatablely equipped with respectively horizontally disposed valve plate 6, wherein the valve plate plate end top on cell body 3 left side walls is supported in stop bit seat bottom, baffle plate left side, valve plate plate end bottom on cell body 3 right side walls is supported at stop bit seat top, baffle plate right side.Cell body 3 left side wall stop bit seat bottoms, right side wall stop bit seat top are respectively arranged with sealing layer 7.
Claims (2)
