Description
Technical field
The utility model belongs to valve manufacture field, especially relates to a kind of to folder rotary-open type single-plate check valve.
Background technique
At present, general safety check can be used as the device preventing medium from flowing backwards and is widely used in the industrial departments such as water supply system, oil, chemical industry, metallurgy, but it is anxious to be modified that existing safety check also has following shortcoming: 1, because seal ring is arranged on valve plate, when pipeline medium passes through, the fluid scouring seal ring at pipeline center position, the seal ring be arranged on valve plate easily comes off, and sealing is poor; 2, be unfavorable for passing through of pipeline medium, time have the phenomenon of choked flow to occur, and installation and maintenance cleaning is inconvenient, causes shorten working life; 3, unbalance stress when valve plate is closed, can not quick closedown, produces water hammer, and working life shortens.
Model utility content
The purpose of this utility model is to provide and a kind ofly realizes good sealing effect, adopt torsion spring can make valve plate quick closedown, significantly can reduce water hammer, have that structure is simple, installation and maintenance are convenient, sealing is reliable and the advantage such as long service life to folder rotary-open type single-plate check valve.
The technical solution of the utility model is: a kind of to folder rotary-open type single-plate check valve, comprise valve seat, suspension ring, valve body and valve plate, described valve seat top is provided with suspension ring, suspension ring are fixedly connected with valve seat, valve seat inside is provided with valve body, described valve body is fixedly connected with valve seat, valve plate is provided with in described valve body, it is characterized in that: be provided with between described valve plate and valve body and seal O type circle, described valve plate is provided with valve plate rotating shaft, valve plate rotating shaft two ends are fixedly connected with valve body, described valve plate top is provided with torsion spring rotating shaft, described torsion spring rotating shaft is provided with torsion spring, described torsion spring rotating shaft two ends are fixedly connected with valve body, described valve plate is provided with torsion spring fixed groove, the head that gets rid of of described torsion spring is placed in torsion spring fixed groove.
Further, described valve body is provided with trapezoidal groove.
Further, described sealing O type circle is arranged in trapezoidal groove.
Further, described torsion spring rotating shaft is fixedly connected with valve body by screw.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, good sealing effect can be realized, adopt torsion spring can make valve plate quick closedown, significantly can reduce water hammer, have that structure is simple, installation and maintenance are convenient, sealing is reliable and the advantage such as long service life.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Structural representation as of the present utility model in Fig. 1, Fig. 2 right side of the present utility model generalized section, shown in the A place partial enlarged drawing of Fig. 3 right side of the present utility model generalized section, the utility model provides a kind of to folder rotary-open type single-plate check valve, comprise valve seat 7, suspension ring 6, valve body 1 and valve plate 3, described valve seat 7 top is provided with suspension ring 6, suspension ring 6 are fixedly connected with valve seat 7, valve seat 7 inside is provided with valve body 1, described valve body 1 is fixedly connected with valve seat 7, valve plate 3 is provided with in described valve body 1, be provided with between described valve plate 3 and valve body 1 and seal O type circle 2, described valve plate 3 is provided with valve plate rotating shaft 11, valve plate rotating shaft 11 two ends are fixedly connected with valve body 1, described valve plate 3 top is provided with torsion spring rotating shaft 4, described torsion spring rotating shaft 4 is provided with torsion spring 5, described torsion spring rotating shaft 4 two ends are fixedly connected with valve body 1, described valve plate 3 is provided with torsion spring fixed groove 9, the head that gets rid of of described torsion spring 5 is placed in torsion spring fixed groove 9.
Further, described valve body is provided with trapezoidal groove 10.
Further, described sealing O type circle 2 to be arranged in trapezoidal groove 10.
Further, described torsion spring rotating shaft 4 is fixedly connected with valve body 1 by screw 8
The working procedure of this example: the utility model is made up of component such as valve body 1, sealing O shape circle 2, valve plate 3, torsion spring rotating shaft 4, torsion spring 5 and suspension ring 6.Valve plate 3, torsion spring 5 and torsion spring rotating shaft 4 are loaded the relevant position of valve body 1, and work good, refill and mix screw 8, it is made to limit the movable of valve plate 3 and valve plate rotating shaft 11, adopt torsion spring 5 can make valve plate 3 quick closedown, prevent the generation of medium refluence phenomenon, and the sealing O shape sealed is enclosed 2 replaceable.
Valve body 1 latus rectum both sides are provided with trapezoidal groove 10, are arranged on and valve body 1 can prevent effectively sealing O type circle 2 from coming off, and the fluid scouring that compared with being arranged on valve plate 3 with sealing O type circle 2, the former avoids pipeline center position seals O type circle 2.Torsion spring fixed groove 9 on valve plate 3, its effect is permanent twist spring 5, prevents moving left and right of torsion spring 5, when valve plate 3 is opened, can ensure that the stressed of each position of valve plate 3 is the same, thus improve working life of the present utility model.
In sum, the utility model can realize good sealing effect, adopts torsion spring 5 can make valve plate 3 quick closedown, significantly can reduce water hammer, have that structure is simple, installation and maintenance are convenient, sealing is reliable and the advantage such as long service life.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
