Abstract
Disclosed is a butterfly valve body rubber sleeve connecting device. The butterfly valve body rubber sleeve connecting device is composed of a rubber sleeve, backs, shaft holes and sealing rings. The rubber sleeve of the butterfly valve is pipe-shaped, he backs are respectively arranged at two ends of the rubber sleeve, and the sealing rings are arranged outside the backs. The outer diameter of each sealing ring corresponds to the diameter of a valve body, the inner diameter of each sealing ring is provided with a groove corresponding to a protrusion of a back, and the concentric shaft holes are symmetrically arranged on the rubber sleeve. The butterfly valve body rubber sleeve connecting device is reasonable in design and tight in sealing because a sealing combining surface of the valve body and a pipeline flange is widened.
Description
Technical field
The utility model relates to the gum cover of pipeline butterfly valve, especially a kind of butterfly valve body gum cover linked set.
Background technique
At present, original gum cover is hard backrest, and gel content mostly is 40% most, and finished product is harder, in assembling and the cooperating of valve body, can occur big or small improperly, and the excessive poorly sealed or too little installation in slit is not gone up, or gum cover phenomenons such as crackle, bulge occur and directly becomes waste product.The axis hole that two reservations are arranged at the gum cover two ends, hard backrest gum cover axis hole place poorly sealed leaking from axis hole occur through regular meeting and enters valve body, causes valve body to damage.Gum cover is originally as the round structure thing, the finished product butterfly valve is connected pressing from both sides by the flange on gum cover itself and the pipeline when piping erection, and the circular tangent plane width of gum cover itself is limited, flange with have only cooperating of gum cover seldom a part of, easily cause and leak or the crushing gum cover, cause valve not use.
In view of above-mentioned many reasons, need to improve the link of pipeline valve body gum cover.
The model utility content
The utility model is for understanding the sealed faying face of having widened valve body and piping flange company of butterfly valve, by rational design, a kind of butterfly valve body gum cover linked set is provided, widened the cooperation width when being connected with piping flange, minimum reducing to from the probability that leaks of sealed faying face, prolonged working life.
The utility model adopts following technological scheme in order to realize above-mentioned goal of the invention: by gum cover, backrest, axis hole, seal ring constitutes, and the gum cover of butterfly valve is a tubulose, and the gum cover two ends are provided with backrest, backrest arranged outside seal ring.
The seal ring external diameter is corresponding with the valve body external diameter, and the seal ring internal diameter is provided with the projection of the corresponding backrest of groove, is symmetrical arranged concentric axis hole on the gum cover.
Beneficial effect: the utility model installs seal ring additional in the gum cover outer ring, and thickness is concordant with cushion rubber protrusion valve body height, and width is concordant with the valve body outer rim, is bonded on the valve body with glue.Because seal ring is dismountable, leaks or can play seal action better when tight with the piping erection flange seal at gum cover.Dismounting is very convenient, and can play the effect of secondary seal, it has guaranteed the circular transverse cross-sectional of gum cover and pipeline adpting flange, directly encased valve body, widened the cooperation width when being connected with piping flange, minimum reducing to from the probability that leaks of sealed faying face, the big loss of avoiding leaking outside and causing.Handsome in appearance, economical with materials prolongs valve working life.Appropriate design is widened the sealed faying face of valve body and piping flange, seals tight.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is: the general assembly structural representation.
Fig. 2 is: the structural representation of seal ring.
Among Fig. 1,2: gum cover 1, backrest 2, axis hole 3, seal ring 4.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
As shown in Figure 1, 2; The gum cover 1 of butterfly valve is a tubulose, and gum cover 1 two ends are provided with backrest 2, backrest 2 arranged outside seal rings 4.Seal ring 4 external diameters are corresponding with the valve body external diameter, and seal ring 4 internal diameters are provided with the projection of the corresponding backrest 2 of groove, are symmetrical arranged concentric axis hole 3 on the gum cover 1.
Claims (2)
1. butterfly valve body gum cover linked set, be by gum cover (1), backrest (2), axis hole (3), seal ring (4) constitutes, and it is characterized in that: the gum cover of butterfly valve (1) is a tubulose, gum cover (1) two ends are provided with backrest (2), backrest (2) arranged outside seal ring (4).
2. according to a kind of butterfly valve body gum cover linked set described in the claim 1, it is characterized in that: seal ring (4) external diameter is corresponding with the valve body external diameter, seal ring (4) internal diameter is provided with the projection of the corresponding backrest of groove (2), is symmetrical arranged concentric axis hole (3) on the gum cover (1).
