Abstract
The utility model relates to a butterfly valve with a spherical surface sealing structure. A valve seat is of a cylindrical structure integrally made of rubber, a valve rod mounting hole is radially and coaxially formed in the middle portion of the valve seat, and a valve rod radially penetrates through the valve rod mounting hole; outer edges of two axial ends of the valve seat are provided with convex rings, and the convex rings are embedded in valve seat mounting grooves formed in two axial ends of a valve body; the inner wall of the middle portion of the valve seat is coaxially provided with an arc-shaped sealing convex ring, the cross section of the arc-shaped sealing convex ring is provided with an inwards concave arc-shaped curved surface and is in sliding fit with the edge of a dish plate in a sealing manner. An arc-shaped sealing structure is arranged at the sealing position of the valve seat of the butterfly valve and the dish plate, and the sealing structure is made of an elastic rubber material and integrated with the valve seat, so that the sealing property of the dish plate and the valve seat is effectively ensured; the dish plate is embedded in a groove of the arc-shaped sealing structure at a closed position, so that the sealing property of the valve is effectively ensured.
Description
Technical field
The utility model belongs to valve field, especially a kind of butterfly valve that is shaped with ball face sealing structure.
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 that is shaped with ball face sealing structure 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 that is shaped with ball face sealing structure, comprise valve body, valve rod, valve seat, dish plate, Joystick 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 Joystick, in valve body, axial seal is provided with a valve seat, dish plate is radially installed on the valve rod in valve seat, this dish plate is fixedly mounted with by axial bolt and a valve rod, and dish plate rotation under the twisting force of valve rod, 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, valve rod is radially through valve rod mounting hole, the axial two ends outer rim of valve seat is all shaped with bulge loop, and this bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body, valve seat middle part inwall is coaxially shaped with an arc sealing bulge loop, and the cross section of this arc sealing bulge loop is shaped with the arc-shaped curved surface of indent, coordinates with the edge slipper seal of dish plate.
And the valve seat outer wall of described arc sealing bulge loop corresponding position is coaxially shaped with bulge loop, this middle part bulge loop is inlaid in the limited ring groove that in valve body, correspondence is made.
And described bulge loop, arc sealing bulge loop and valve seat all adopt elastic caoutchouc material one to make.
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 valve seat of this butterfly valve and dish plate sealing station are shaped with arc sealing configuration, the employing of sealing structure has flexible quality of rubber materials and valve seat one is made, effectively guarantee the sealing of dish plate and valve seat, the operating position of dish plate is inlaid in the groove of arc sealing configuration, effectively guarantees the sealing of valve.
4, the utility model structural strength is high, good seal performance, and also this valve easily controls, and helps operator to be more prone to grasp flow situation, and simple in structure, and the installation of valve part is simple, long service life.
