Description
Technical Field
The utility model relates to a valve barrel field of making, concretely relates to valve barrel for high performance electric gate valve.
Background
In the design of mechanical parts, there are many kinds of valve sleeves and different shapes. Certain valve sleeves with pure rubber have insufficient strength, are easy to rotate in the using process and are not firmly connected.
The traditional rubber valve sleeve is in line contact with a to-be-connected piece, such as a C-shaped valve sleeve, a V-shaped valve sleeve and the like. The existing valve sleeve is not high enough in strength and large in leakage amount, and rubber materials are easily extruded into the plane of the metal ring to influence the installation stability, the sealing performance and the like of the bolt. Especially, in the case of a valve sleeve applied to a high-pressure container, the common valve sleeve is easy to leak, deform and fail, and is easy to cause mechanical failure in serious cases.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects of the prior art, the present invention provides a valve sleeve for a high-performance electric gate valve.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
a valve housing for a high performance power gate valve comprising:
the valve sleeve comprises a valve sleeve body, wherein the middle part of the valve sleeve body is provided with an installation through groove, the outer side of the valve sleeve is sequentially provided with a first convex part, a first concave part and a second convex part from the bottom to the sealing surface between the end surface of a flange, and a first iron ring is arranged in the end surface of the flange; and a second iron ring is arranged in the first concave part.
In a preferred embodiment of the present invention, the chamfer angle of the first convex portion is 0.096 degrees.
In a preferred embodiment of the present invention, the chamfer angle of the second convex portion is 0.156 degrees.
In a preferred embodiment of the present invention, the first concave portion and the first convex portion or the second convex portion are connected by an arc section, and the radian of the arc section is 0.063 degrees.
In a preferred embodiment of the present invention, the bottom of the valve housing is a slope, and the slope angle of the slope is 20 degrees.
In a preferred embodiment of the present invention, the valve sleeve is made of rubber, the hardness of the rubber is 50 degrees, the strength is higher than 20Mpa, the elongation at break is 500%, and the compression set is 25%.
The beneficial effects of the utility model reside in that:
the utility model provides a better stability of valve barrel performance for high performance electric gate valve, the leakproofness is better, can effectively avoid leaking and the trouble that the deformation ageing leads to.

Fig. 2 is a partial enlarged view of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 or 2, the valve sleeve for a high-performance electric gate valve includes a valve sleeve body 100, wherein a mounting through groove 110 is formed in the middle of the valve sleeve body 100, a first convex portion 131, a first concave portion 132 and a second convex portion 133 are sequentially formed on a sealing surface 130 between the bottom of the valve sleeve body 100 and a flange end surface 120, and a chamfer angle of the first convex portion 131 is 0.096 degree. The chamfer of the second protrusion 133 was 0.156 degrees. The first concave portion 132 and the first convex portion 131 or the second convex portion 133 are connected by an arc section 135, and the arc of the arc section 135 is 0.063 degree. A first iron ring 121 is arranged in the flange end face 120; a second iron ring 134 is mounted in the first recess 132. The bottom of the valve sleeve 100 is a sloped surface 140, and the sloped surface 140 is inclined at an angle of 20 degrees.
Because of possessing the above structure, the utility model has the advantages that:
first, the valve housings are used in high-end electric gate valves, one gate valve is provided with two valve housings, and sealing is achieved by close contact between the knife and the valve housings.
Secondly, compared with the common pure rubber valve sleeve, an iron ring is respectively added between the sealing surface and the flange surface of the valve sleeve to enhance the strength of the valve sleeve, facilitate the fixation and enhance the sealing property. Even under high pressure environment, will not produce leakage and deformation.
Thirdly, the hardness of the valve sleeve rubber material is 50 degrees, the strength reaches more than 20Mpa, the elongation at break reaches 500 percent, and the compression permanent deformation is 25 percent. The project achieves the best use quality by reasonably optimizing various indexes influencing the performance of the valve sleeve. But different rubber materials can be selected according to different characteristics of various fluids of the gate valve, so that different performance requirements are met.
Fourthly, the design of combining the concave-convex parts is adopted, so that the valve sleeve can be tightly attached to the valve body when being installed, and the valve cannot generate deviation and leakage when working.
