Abstract
The utility model relates to a butterfly valve with a valve seat of a strengthened structure. The valve seat is prepared from rubber through integral molding and is a cylindrical structure; a valve rod installation hole is radially and coaxially formed in the middle of the valve seat; a convex edge ring is arranged at the outer edge of each of the two axial ends of the valve seat and is embedded into a valve seat installation groove which is formed in each of the two axial ends of a valve body; a convex middle ring is coaxially arranged on the outer wall of the middle of the valve seat and is embedded into a limiting ring groove which is correspondingly formed in the valve body. The butterfly valve is high in structural strength, and can be applied to installation and use of pipelines of various standards; the problems of high cost, large stock and the like caused by manufacturing of products of various specifications for an enterprise are solved; moreover, the butterfly valve is easy to control, simple in structure and long in service life, and assists an operator in more easily mastering the flow situation; valve parts are easy to install.
Description
Technical field
The utility model belongs to valve field, especially a kind of butterfly valve with reinforcement structure valve seat.
Background technique
Use at engineering pipeline transportation art valve is very extensive, the basic structure of valve is co-axial seal setting-in valve seat in valve body now, valve rod is radially installed on valve body, on valve rod in valve body, be fixedly mounted with dish plate, dish plate coordinates with valve base sealing, thereby dish plate rotation or movement under the driving of valve rod open and close the runner in valve seat; Valve body outer radial is shaped with a plurality of flange plates for being connected with pipeline, is shaped with bolt mounting holes on flange plate.But the sealability of rubber valve seat and dish plate be valve important indicator sealing be difficult to ensure card, especially, after long-term use, valve seat rubber deformation, causes sealing problem.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of butterfly valve of strengthening structure valve seat that has of reasonable in design, simple in structure, easy to operate, long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of butterfly valve with reinforcement structure valve seat, comprise valve body, valve rod, valve seat, dish plate, handle and bolt, valve body middle part is radially provided with a valve rod, this valve rod upper end is stretched out valve body and is coaxially installed with handle, in valve body, axial seal is provided with valve seat, dish plate is installed on the valve rod in valve seat, it is characterized in that: described valve seat is the one-body molded cylinder barrel shaped structure of making of rubber, this valve seat middle part is radially coaxially shaped with valve rod mounting hole; The axial two ends outer rim of valve seat is all shaped with edge bulge loop, and this edge bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body; Valve seat middle part outer wall is coaxially shaped with a middle part bulge loop, and this middle part bulge loop is inlaid in the limited ring groove that in valve body, correspondence is made.
And the edge bulge loop at described two ends and middle part bulge loop and valve seat one are made.
And described valve outer wall spaced radial is shaped with a plurality of mounting plates, on the plurality of mounting plate, be all shaped with mounting hole.
Advantage of the present utility model and good effect are:
1, the support performance of the rubber gasket of this butterfly valve is good, and firmly stable, simple and compact for structure, adjusting function is good, guarantees to support moment not yielding again.
The deformation effects such as 2, the machining accuracy of this butterfly valve is high, and valve seat is not yielding, and tolerance is little, the expansion upheaval of valve seat are little, the long service life of valve seat.
3, the utility model structural strength is high, can be suitable for installing and using of multiple standards pipeline, having reduced enterprise's manufacture plurality of specifications product causes cost high, the problems such as quantity in stock is large, and this valve easily controls, help operator to be more prone to grasp flow situation, and simple in structure, the installation of valve part is simple, long service life.

Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of butterfly valve with reinforcement structure valve seat, comprise valve body 3, valve rod 2, valve seat 4, dish plate 5, handle 1 and bolt 6, if accompanying drawing 1 is to as shown in accompanying drawing 2, valve body middle part is radially provided with a valve rod, this valve rod upper end is stretched out valve body and is coaxially installed with handle, and in valve body, axial seal is provided with valve seat, and dish plate is installed on the valve rod in valve seat, the bolt of this dish plate by middle part and valve rod is fixedly mounted with and rotation under the twisting force of valve rod, thereby the keying of control valve.
Valve outer wall spaced radial is shaped with a plurality of mounting plates 9, is all shaped with a mounting hole on the plurality of mounting plate, for being connected with piping flange.
Innovative point of the present utility model is:
Valve seat concrete structure is shown in that accompanying drawing 3 is to accompanying drawing 5, and described valve seat is the one-body molded cylinder barrel shaped structure of making of rubber, and this valve seat middle part is radially coaxially shaped with valve rod mounting hole 10; The axial two ends outer rim of valve seat is all shaped with edge bulge loop 8, and this edge bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body; Valve seat middle part outer wall is coaxially shaped with a middle part bulge loop 7, and this middle part bulge loop is inlaid in the limited ring groove that in valve body, correspondence is made, and this valve seat construction is simple, effectively prevent that valve seat from moving axially, good stability, and middle part is shaped with that to strengthen the valve seat intensity of bulge loop large, avoids the distortion of valve seat protuberance.
The edge bulge loop at described two ends and middle part bulge loop and valve seat one are made.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
