Abstract
The utility model discloses a butterfly valve plate ball-shaped sealing face structure. The butterfly valve plate ball-shaped sealing face structure comprises a valve plate and a valve seat and is characterized in that the outer edge surface of the valve plate is a ball-shaped face, the inner wall, used for being sealed with the valve plate, of the valve seat is an inward concave cambered surface which is adapted to the ball-shaped face of the valve plate, and the ball-shaped face and the inward concave cambered surface are sealed with each other to form a ball-shaped sealing surface. The butterfly valve plate ball-shaped sealing face structure has the advantages that the ball-shaped face and the inward concave cambered surface are sealed with each other to form the ball-shaped sealing surface, the sealing performance of the ball-shaped sealing surface is superior to the sealing performance of a smooth sealing surface in the prior art, and the valve plate and the valve seat are made to more tightly wrap each other through the ball-shaped sealing surface.
Description
Technical field
The utility model relates to the butterfly valve field, particularly a kind of butterfly valve plate spherical seal surface structure.
Background technique
Referring to illustrated in figures 1 and 2, present valve plate 20 all is round pie, and the inwall of valve seat 10 is the smooth ring surface that adapts to round pie, both sealings place are smooth sealing surface 30, but both wrap up imprecision mutually, so valve plate 20 is good not with the sealing of valve seat 10, cause easily butterfly valve to leak.
The model utility content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, and a kind of butterfly valve plate spherical seal surface structure is provided, and this butterfly valve plate spherical seal surface sealing structure is good, wraps up tightr.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of butterfly valve plate spherical seal surface structure, comprise valve plate and valve seat, it is characterized in that, the outer fringe surface of described valve plate is spherical, the inner concave arc surface that the inwall that described valve seat is used for sealing with valve plate adapts for the spherical with described valve plate, spherical and inner concave arc surface mutually seal and form a spherical seal surface.
Owing to adopted technological scheme as above, the beneficial effects of the utility model are: spherical and inner concave arc surface mutually seal and form a spherical seal surface, the sealing of spherical seal surface is better than the smooth sealing surface of prior art, and spherical seal surface makes valve plate and valve seat wrap up tightr.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the connection diagram of valve plate and the valve seat of prior art.
Fig. 2 is the I place enlarged view of Fig. 1.
Fig. 3 is the structural representation of a kind of butterfly valve plate spherical seal surface of the utility model structure.
Fig. 4 is the II place enlarged view of Fig. 3.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 3 and shown in Figure 4, a kind of butterfly valve plate spherical seal surface structure comprises valve plate 200 and valve seat 100, the outer fringe surface of valve plate 200 is spherical 210, the inner concave arc surface 110 that the inwall that valve seat 100 is used for sealing with valve plate 200 adapts for the spherical 210 with valve plate 200, spherical 210 mutually seals with inner concave arc surface 110 and forms a spherical seal surface 300, the sealing of spherical seal surface 300 is better than the smooth sealing surface of prior art, and spherical seal surface 300 makes valve plate 200 and valve seat 100 wrap up tightr.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
