Abstract
The utility model discloses a valve body valve seat connection structure of a butterfly valve. The valve body valve seat connection structure of the butterfly valve comprises a valve body and an elastic valve seat. The elastic valve seat is installed in the valve body. Outer edges of two ends of the elastic valve seat extend outwards to form extension edges. The extension edges are attached to the edge of the valve body. According to the valve body valve seat connection structure of the butterfly valve, due to the facts that the extension edges are arranged on the outer edges of the two ends of the valve seat and are connected with the edge of the valve body in an attached mode, when the butterfly valve is used for installation, the extension edges can be directly used for forming seal, a sealing element is free of being additionally arranged between the valve body and a connecting pipe, and compared with independently separately sealing, the valve body valve seat connection structure of the butterfly valve is good in sealing effect, reduces butterfly valve torsion force, and prolongs service life of the butterfly valve.
Description
Technical field
The utility model relates to the butterfly valve technical field, particularly a kind of valve body of butterfly valve and valve seat connecting structure.
Background technique
Butterfly valve, as a kind of disc type open-shut device, its realize about by reciprocating rotating 90 degree the fluid passage unlatching, close and regulate.Because simple in structure, volume is little, and is lightweight, material consumption is economized, and installation dimension is little, and driving moment is little, and is easy and simple to handle, rapid, but also can have simultaneously good flow regulating function and close sealing characteristics, is used widely.
Butterfly valve generally includes by valve body, the valve seat, valve rod and the flap that are located in the valve body and forms, by valve rod by bearing rotate to realize flap turn round to realize the fluid passage unlatching, close and regulate.
Existing valve seat all is to reinstall in the valve body after being separately made with valve body usually; such valve seat and valve body only are that the inwall extruding by its outer wall and valve body links together; thereby; when butterfly valve is installed in the pipeline; butterfly valve prevents the liquid leakage with usually needing to use separately rubber gasket being connected of pipeline coupling flange to seal; inconvenience increases installation procedure, be not easy to install, and the sealing effect between its pipeline coupling flange is also bad.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency and valve body and valve seat connecting structure that a kind of butterfly valve is provided.
For achieving the above object, the technological scheme that adopts of the utility model is as follows:
A kind of valve body of butterfly valve and valve seat connecting structure, comprise valve body and elastic seat, described elastic seat is installed in the described valve body, and described elastic seat two ends outward edge stretches out and form to extend the edge, and described extension is along being fitted on the edge of described valve body.
Extension at described elastic seat convexes with the circular seal stiffening ring along the surface.
Be provided with adhesive layer between the surface of contact of described elastic seat and described valve body.
Described elastic seat is that rubber is made.
The utility model is provided with by the outward edge at the valve seat two ends and extends the edge, and described the extension along the edge with valve body is fitted and connected together, thereby, when utilizing such butterfly valve to install, directly can utilize described extension to seal along forming, and needn't between valve body and connecting tube, set up again Sealing, and such sealing means is compared than sealing separately separately, have good sealing effect, and can reduce the butterfly valve torque force, prolong the working life of butterfly valve.
Description of drawings
Figure 1 shows that the valve body of the butterfly valve that the utility model embodiment provides and the structural representation of valve seat connecting structure;
Figure 2 shows that the structural representation of the elastic seat that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Fig. 1 ~ 2, the figure shows the valve body of the butterfly valve that the utility model embodiment provides and the structure of valve seat connecting structure.For convenience of explanation, only show the part relevant with the utility model embodiment.
A kind of valve body of butterfly valve and valve seat connecting structure, comprise valve body 1 and elastic seat 2, described elastic seat 2 is installed in the described valve body 1, and described elastic seat 2 two ends outward edges stretch out and form to extend along 20, and described extension is fitted on the edge of described valve body 1 along 20.
Referring to shown in Figure 2, convex with circular seal stiffening ring 21 in the extension of described elastic seat 2 along 20 surfaces.
Be provided with adhesive layer between the surface of contact of described elastic seat 2 and described valve body 1.
Described elastic seat 2 is made for rubber.
The utility model is provided with by the outward edge at the valve seat two ends and extends the edge, and described the extension along the edge with valve body is fitted and connected together, thereby, when utilizing such butterfly valve to install, directly can utilize described extension to seal along forming, and needn't between valve body and connecting tube, set up again Sealing, and such sealing means is compared than sealing separately separately, have good sealing effect, and can reduce the butterfly valve torque force, prolong the working life of butterfly valve.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
1. the valve body of a butterfly valve and valve seat connecting structure, comprise valve body and elastic seat, it is characterized in that described elastic seat is installed in the described valve body, and described elastic seat two ends outward edge stretches out to form and extends the edge, and described extension is along being fitted on the edge of described valve body.
2. the valve body of butterfly valve according to claim 1 and valve seat connecting structure is characterized in that, convex with the circular seal stiffening ring along the surface in the extension of described elastic seat.
