Abstract
The utility model relates to a butterfly valve body seal structure which comprises a valve body. An inner annular rubber layer is vulcanized on the inner wall of the valve body. An outer annular rubber layer is vulcanized on the inner side of each of the two end faces of the valve body. The outer annular rubber layers and the inner annular rubber layer are integrated. Due to the fact that the outer annular rubber layers and the inner annular rubber layer are integrated, simple machining process is achieved, the outer annular rubber layers can replace original seal rings to allow the valve body to be simply and fast connected with a pipeline flange plate, work efficiency is increased effectively, cost is lowered, a plurality of annular grooves are formed on the surface of each outer annular rubber layer, friction force between the outer annular rubber layers and the flange plate can be increased effectively to allow the two to be combined tightly, and seal performance can be increased effectively.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of dish valve, specifically, is a kind of butterfly valve body sealing configuration.
Background technique
For the valve plate that guarantees butterfly valve and the sealability of valve body, usually at valve interior wall middle part sulfuration one deck rubber ring, improved widely thus the sealing problem of valve plate and valve body.When valve body is connected with pipeline flanges, usually need to install seal ring additional, the mounting hole of seal ring must with could install after the mounting hole of flange plate and valve body is aimed at, so this procedure is more complicated, once seal ring is not in place, will produce leakage.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of butterfly valve body sealing configuration is provided, and this is simple in structure, quick and easy for installation, has effectively improved the sealability of valve body and pipeline.
Scheme of the present utility model is achieved in that
A kind of butterfly valve body sealing configuration, comprise valve body, and this valve interior wall vulcanizes an interior ring-shaped rubber layer, and an outer ring rubber layer is vulcanized respectively in the both ends of the surface inboard of described valve body, and this outer ring rubber layer and interior ring-shaped rubber layer are integrated.
And described two outer ring rubber layer radial surface intervals are shaped with a plurality of annular grooves.
Advantage of the present utility model and good effect are:
The interior ring-shaped rubber layer of this structure and outer ring rubber layer are integrated to be made, processing technology is simple, the alternative original seal ring of outer ring rubber layer, make the simple and fast that is connected of valve body and pipeline flanges, effectively increase work efficiency, and reduced cost, ring-shaped rubber layer surface is shaped with a plurality of annular grooves outside, can effectively increase the frictional force between outer ring rubber layer and flange plate, make the two in conjunction with tightr, effectively improve sealability.
The accompanying drawing explanation
Fig. 1 is structure master map of the present utility model;
The A-A that Fig. 2 is Fig. 1 is to sectional view (hiding valve plate);
The I section enlarged view that Fig. 3 is Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
A kind of butterfly valve body sealing configuration, the structure of this butterfly valve as shown in Figure 1, comprises valve body 1 and the movable valve plate 2 be inlaid in valve body, at valve interior wall, vulcanizes an interior ring-shaped rubber layer 4.
Innovative point of the present utility model is:
An outer ring rubber layer 3 is vulcanized respectively in the both ends of the surface inboard of described valve body, and this outer ring rubber layer and interior ring-shaped rubber layer are integrated.
Described two outer ring rubber layer radial surface intervals are shaped with a plurality of annular grooves 5.
Advantage of the present utility model is:
The alternative original seal ring of described outer ring rubber layer, make the simple and fast that is connected of valve body and pipeline flanges, effectively increase work efficiency, and reduced cost, ring-shaped rubber layer surface is shaped with a plurality of annular grooves outside, can effectively increase the frictional force between outer ring rubber layer and flange plate, make the two in conjunction with tightr, effectively improve sealability.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in embodiment; every other mode of executions that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
