Abstract
The utility model discloses a kind of butterfly valve plate for butterfly valve.A kind of butterfly valve plate, the butterfly valve plate is provided with V-shaped groove on arc-shaped seal surface along annular center line, the butterfly valve plate also has other identical sealing surface part respectively in the both sides of the V-shaped groove notch set on arc-shaped seal surface, and notch both ends and the butterfly valve plate of the V-shaped groove cell wall are in the other identical curved connection in sealing surface part that the V-shaped groove notch both sides set on arc-shaped seal surface have respectively.Butterfly valve plate of the present utility model is in the double-sealing face structure of circular arc, in the utility model butterfly valve plate of circular arc double-sealing face structure, due to increasing Fluid Sealing path, sealing function twice, improve the sealing of butterfly valve plate and valve body, butterfly valve product qualification rate is improved, and also reduces the manufacturing cost of butterfly valve plate.
Description
Technical field
The utility model belongs to a kind of annex articles for use of butterfly valve, especially belongs to a kind of butterfly valve plate.
Background technology
At present, traditional butterfly valve plate sealing surface seals in circular arc and with butterfly valve seat list sealing surface mostly, due to butterfly
Valve sealing surface of valve plate sealed pathway is short, and sealing effectiveness is bad, and it is not high leak, butterfly valve qualification rate easily occur.For this many producer
Butterfly valve plate sealing effectiveness is improved by increasing rubber compression ratio, but is the increase in butterfly valve plate manufacturing cost.How to improve
Butterfly valve plate sealing, butterfly valve product qualification rate is improved, but also it is to need to solve the problems, such as to reduce butterfly valve plate manufacturing cost.
Utility model content
Technical problem to be solved in the utility model is：A kind of butterfly valve plate is provided.Can not only using the butterfly valve plate
Butterfly valve plate sealing is improved, improves butterfly valve product qualification rate, and butterfly valve plate manufacturing cost can also be reduced.
The utility model solve above-mentioned technical problem technical scheme be：A kind of butterfly valve plate, it is characterized in that：The butterfly valve
Valve plate is provided with V-shaped groove on arc-shaped seal surface along annular center line, and the butterfly valve plate is in the V set on arc-shaped seal surface
The both sides of shape groove notch also have other identical sealing surface part, notch both ends and the butterfly valve of the V-shaped groove cell wall respectively
The other identical curved company in sealing surface part that valve plate has respectively in the V-shaped groove notch both sides set on arc-shaped seal surface
Connect；
The groove depth of the V-shaped groove is 0.6-1 ㎜, and the V-shaped groove cell wall and the butterfly valve plate are in arc-shaped seal surface along ring
The angle of shape cross-sectional centerline is 75-80 °.
The beneficial effects of the utility model are：Because butterfly valve plate of the present utility model is in along annular on arc-shaped seal surface
Center line is provided with V-shaped groove, and the butterfly valve plate also has another respectively in the both sides of the V-shaped groove notch set on arc-shaped seal surface
Outer identical sealing surface part, notch both ends and the butterfly valve plate of the V-shaped groove cell wall are in the V set on arc-shaped seal surface
The other identical curved connection in sealing surface part that shape groove notch both sides have respectively.By butterfly valve plate of the present utility model in circle
Arc sealing surface has been arranged to the double-sealing face structure in circular arc, in the utility model butterfly valve of circular arc double-sealing face structure
Valve plate, due to increasing Fluid Sealing path, sealing function, improves the sealing of butterfly valve plate and valve body, improves twice
Butterfly valve product qualification rate, and also reduce the manufacturing cost of butterfly valve plate.Existing butterfly valve plate list sealing surface is overcome to exist
Sealing effectiveness it is bad, easily there is the defects of leak, overcome existing butterfly valve plate by increasing rubber compression ratio to improve
Butterfly valve plate sealing effectiveness, increase butterfly valve plate manufacturing cost the defects of.
