Abstract
The utility model discloses a valve body for a valve. A groove is arranged in the valve body. A seal ring is arranged in the groove. A rubber layer is formed on an annular inner wall of the groove. The longitudinal section of the rubber layer is semiarc-shaped. The thickness of the rubber layer gradually decreases from the end face to bottom. A plurality of protrusion bodies are formed and evenly distributed on the surface of the rubber layer. The valve body for the valve has the advantages that structure is simple and exquisite and seal performance is greatly improved.
Description
Technical field
The utility model relates to a kind of for the valve body on the valve.
Background technique
There is sealing problem in valve in the existing product, service time one is of a specified duration, and poor sealing performance causes leaking, and makes troubles to the client, is unfavorable for long-run development.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research to this, design a kind of for the valve body on the valve, exquisiteness simple in structure, sealability improves greatly, this case produces thus.
Summary of the invention
The purpose of this utility model is in order to provide a kind of for the valve body on the valve, exquisiteness simple in structure, and sealability improves greatly.
For achieving the above object, the technical solution of the utility model is:
Be used for the valve body on the valve, be provided with groove at valve body, be provided with seal ring in this groove, it is characterized in that: form rubber layer on the annular inner wall of described groove, the longitudinal section of described rubber layer is half arc, the thickness of this rubber layer down dwindles gradually from end face, forms equally distributed convex body on the surface of rubber layer.
Further, the altitude range of described rubber layer is at 0.1-1mm.
The beneficial effects of the utility model: the utility model valve body is provided with groove, be provided with seal ring in this groove, form rubber layer on the annular inner wall of described groove, the longitudinal section of described rubber layer is half arc, the thickness of this rubber layer down dwindles gradually from end face, form equally distributed convex body on the surface of rubber layer, such setting, can improve the seal degree between groove and the seal ring, seal ring is limited in the groove, and rubber layer is enough to carry out buckle to seal ring, simultaneously, so that seal ring is extruded, form high-intensity sealing.
In order to improve sealing effect, form equally distributed convex body on the surface of rubber layer, convex body can and seal ring between form good sealing effect, simultaneously and between the seal ring good frictional property is arranged, so can form good sealing effect.
As from the foregoing, the utility model exquisiteness simple in structure, sealability improves greatly.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to the accompanying drawings 1, the present embodiment discloses a kind of for the valve body on the valve, be provided with groove 2 at valve body 1, be provided with seal ring in this groove 2, it is characterized in that: form rubber layer 3 on the annular inner wall of described groove 2, the longitudinal section of described rubber layer 3 is half arc, and the thickness of this rubber layer 3 down dwindles gradually from end face, forms equally distributed convex body 4 on the surface of rubber layer 3.
Further arrange, the altitude range of described rubber layer 3 is at 0.1-1mm.
As from the foregoing, the utility model exquisiteness simple in structure, sealability improves greatly.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
