Abstract
The utility model provides a kind of seal ring for butterfly valve and comprises its butterfly valve, wherein, seal ring for butterfly valve includes: the clamping part that is arranged at the outer wall of described seal ring, described clamping part is for being fixed on described seal ring the valve interior wall of described butterfly valve, and described seal ring also comprises that one runs through the outer wall of described seal ring and the through hole of inwall.The utlity model has tightr that seal ring and valve body are fixed, meanwhile, reduced seal ring and in use produced the advantage of wearing and tearing.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of seal ring for butterfly valve and comprise its butterfly valve.
Background technique
The sealing of butterfly valve is that the rotation by butterfly plate realizes folding between itself and seal ring and airtight.But existing butterfly valve seal circle easily produces and slides in the middle of using process.Meanwhile, because seal ring fits tightly on axostylus axostyle, make axostylus axostyle can cause wearing and tearing to itself and seal ring joint in rotation process, in the course of time, can cause medium to reveal from the position being connected with axostylus axostyle of seal ring, cause production accident.
Model utility content
The technical problems to be solved in the utility model is fixing insecure in order to overcome the valve body of existing seal ring and butterfly valve, and axostylus axostyle and seal ring be because of the easy defect of generation leakage of long-term friction, a kind of seal ring for butterfly valve is provided and comprises its butterfly valve.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of seal ring for butterfly valve, its feature is, it includes: the clamping part that is arranged at the outer wall of described seal ring, described clamping part is for being fixed on described seal ring the valve interior wall of described butterfly valve, and described seal ring also comprises that one runs through the outer wall of described seal ring and the through hole of inwall.Axostylus axostyle passes from described through hole, and the butterfly plate of described butterfly valve is fixed on described axostylus axostyle, the folding that the rotation by described butterfly plate realizes butterfly valve with close.
Preferably, described clamping part comprises first snap ring at an edge of the outer wall that is arranged on described seal ring and second snap ring on another side edge that is arranged on the outer wall of described seal ring.Described the first snap ring and described the second snap ring are located on respectively the edge of the outer wall of seal ring.
Preferably, the outer wall of described the first snap ring, described the second snap ring and described seal ring is integrally formed.
Preferably, the inwall of described through hole has some projections.
Preferably, described some projections are dentation.The lug boss branch of through hole fits in axostylus axostyle, effectively plays seal action, and the part not contacting with axostylus axostyle, has reduced the area of contact of seal ring and axostylus axostyle, has reduced frictional force, makes seal ring have longer working life.
A butterfly valve, comprises seal ring as above, and the body wall of described butterfly valve has the valve body recess coordinating with described clamping part, for described clamping part is fixed in described valve body recess.The two side of valve body all has valve body recess, coordinates being fixedly connected with of clamping part.
Preferably, described valve body recess is U-shaped.
Preferably, described valve body recess and described valve interior wall are integrally formed.
Positive progressive effect of the present utility model is: make fixing tightr of seal ring and valve body, meanwhile, reduced seal ring and in use produced wearing and tearing.
Accompanying drawing explanation
Fig. 1 is the utility model for the seal ring of butterfly valve and comprises its butterfly valve one embodiment's the structural representation of butterfly valve.
Fig. 2 is the utility model for the seal ring of butterfly valve and comprises its butterfly valve one embodiment's the structural representation of seal ring.
Description of reference numerals:
Butterfly valve: 1
Butterfly plate: 2
Axostylus axostyle: 3
Seal ring: 4
Through hole: 41
The first snap ring: 42
The second snap ring: 43
Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment 1
Incorporated by reference to Fig. 1, Fig. 2, understood, a kind of seal ring 4 for butterfly valve, includes: the first snap ring 42, second snap ring 43 at two edges that is positioned at the outer wall of seal ring 4.The first snap ring 42, the second snap ring 43 can be integrally formed with the outer wall of seal ring 4.The first snap ring 42, the second snap ring 43 are for being fixed on seal ring 4 valve interior wall of butterfly valve 1.Seal ring 4 has one and runs through the outer wall of seal ring 4 and the through hole of inwall 41.Axostylus axostyle 3 passes from through hole 41, and the butterfly plate 2 of butterfly valve 1 is fixed on axostylus axostyle 3.Butterfly plate 2 is positioned in seal ring 4.When needs are closed butterfly valve 1, butterfly plate 2 pushes mutually with seal ring 4 contacting points, and block media flows to the other end from one end.When needs are opened butterfly valve 1, axostylus axostyle 3 drives butterfly plate 2 half-twists, and butterfly plate 2 both sides separation sealing rings 4 are vacated path and made medium circulation.The inwall of through hole 41 has the projection of some dentations.Owing to adopting the projection of dentation, the lug boss branch of through hole 41 fits in axostylus axostyle 3, effectively plays seal action, and the part not contacting with axostylus axostyle 3, reduced the area of contact of seal ring 4 with axostylus axostyle 3, reduced frictional force, made seal ring 4 there is longer working life.
Embodiment 2
Incorporated by reference to Fig. 1, Fig. 2, understood, butterfly valve 1 comprises butterfly plate 2, axostylus axostyle 3, seal ring 4.The body wall of butterfly valve 1 has the U-shaped valve body recess coordinating with the first snap ring 42, the second snap ring 43.Valve body recess and valve interior wall are integrally formed.During installation, first seal ring 4 is placed in to valve interior wall, the first snap ring 42 of seal ring 4, the second snap ring 43 buckle into valve body recess.Then, in butterfly valve 1 and seal ring 4, put into butterfly plate 2, and make axostylus axostyle 3 through the through hole 41 of the axis hole on butterfly valve 1, seal ring 4 and fix.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these changes and modification all fall into protection domain of the present utility model.
