Abstract
A spherical sealed butterfly valve mainly solves the problems that a valve seat and a butterfly board of an existing butterfly valve are difficult to install in a matched mode and the sealing performance is poor. The spherical sealed butterfly valve is characterized in that a valve seat (3) is fixed in a valve body (1), a concave spherical surface (31) is machined on the valve seat (3), a butterfly board (4) is arranged in the valve seat (3), a convex spherical surface (41) matched with the concave spherical surface (31) is arranged on the butterfly board (4), a containing groove (5) is formed in the convex spherical surface (41), and a first sealing ring (6) is arranged in the containing groove (5). Spherical sealing is adopted by the spherical sealed butterfly valve, so that the sealing performance of the valve is improved, assembly is convenient, the butterfly board is not prone to damage, and the problem that once the butterfly valve is not installed in place, the butterfly valve leaks is solved.
Description
Technical field
The utility model relates to a kind of butterfly valve, is specifically related to a kind of ball face sealing butterfly valve.
Background technique
In prior art, between the valve seat of tradition butterfly valve and butterfly plate, the cylinder inner planes that adopt coordinate more, there is certain drawback in the fit system of this structure: between butterfly plate and valve seat, can not coordinate too tightly, if coordinate too tight, valve switch is just very difficult, if do not exert oneself, is just difficult to Open valve or complete throttle down, and the throttle down of exerting oneself, butterfly plate causes damage with regard to being easy to distortion.Yet, if butterfly plate coordinates defective tightness with valve seat, be easy to produce and leak.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of ball face sealing butterfly valve, mainly solved between the valve seat of existing butterfly valve and butterfly plate, be difficult to coordinate install, the poor problem of sealing.
The technological scheme that the utility model adopts is: a kind of ball face sealing butterfly valve, comprise valve body, valve rod, in described valve body, be fixed with valve seat, on described valve seat, be processed with concave spherical surface, in described valve seat, be provided with butterfly plate, described butterfly plate is provided with the protruding sphere with concave spherical surface adaptation, and described protruding sphere is provided with standing groove, is provided with the first seal ring in described standing groove.
Described butterfly plate one end is provided with square opening, and the other end is provided with circular port, and described valve rod end and square opening are suitable, in described circular port, are provided with rotating shaft, and valve body is inserted in described rotating shaft.
Described valve seat is provided with the circular groove with valve body adaptation, and described circular groove place is provided with two through holes, and described through hole and square opening, circular port align.
Described valve seat and the contacting point of valve body are provided with seal groove, are provided with successively butterfly spring, the seal ring with cone tank, conical seal ring, the second seal ring in described seal groove.
Between described valve rod and valve body, be provided with the 3rd seal ring.
The beneficial effects of the utility model are: adopt ball face sealing, not only promoted the sealing of valve, and easy to assembly, not fragile butterfly plate, solved the butterfly valve seal problem that just can leak not in place.
