Description
Technical field
The present invention relates to a kind of valve plate scribing tooling and scribble methods.
Background technology
Since three-eccentric-butterfly-valve sealing surface is all tilted prick hole, and the sealing of valve body and valve plate all must scalene cone corresponding matching
Sealing, that is, face directly must with face fitted seal directly, valve body inclined-plane corresponding with the sealing of valve plate inclined-plane must seal, sealing surface
Direction will strictly correspond to.And three-eccentric-butterfly-valve valve plate axis hole is eccentric with respect to shape, sealing inclined-plane is being cast relative to the position of axis hole
It has just been fixed when part, and the height of tooling also has direction, so when processing inclined-plane, valve plate and tooling just need pair
Line.In addition, since valve body, valve plate are when complete machine seals, the corresponding matching of scalene cone is needed to seal, so in the conjunction boring of axis hole
It is also required to line in journey, so that facing directly to facing sealing directly, inclined-plane seals inclined-plane.
As shown in Figs. 1-3,100 side of three-eccentric-butterfly-valve valve plate has boss 101, has axis hole 102, axis on boss 101
Hole 102 is eccentric with respect to 100 shape of valve plate, and boss center line n and axis hole center line m is same center line, and in boss center line n
On to bore two fabrication holes 104.Existing scribble method is：First valve plate 100 is erected to come, 101 liang of side planes of levelling boss, be drawn
Go out the center line of the center line and axis hole 102 of valve plate matrix.Valve plate 100 is rotated by 90 ° later, flat center line is leaned on angle square, then
Draw the center line perpendicular to axis hole 102.A stroke axis hole center line m is needed (need to only to draw the technique on axis hole center line m in Fig. 3
Hole 104) and vertical centerline p.This scribble method is cumbersome, and when valve plate 100 is erected and rotated, and is easy pair
Valve plate 100 causes unnecessary damage.
