A method for accurately measuring the angle of the sealing cone surface of the solenoid valve seat

Abstract

The present invention relates to a method for accurately measuring the angle of a solenoid valve seat sealing cone surface. During measurement, two steel balls, one large and one small, are introduced. When the steel balls are placed in the valve seat sealing cone surface, they are tangent to the valve seat sealing cone surface. Thus, after the height difference between the centers of the two steel balls is measured, a valve seat sealing cone surface diagram can be drawn, and the sealing cone surface angle ø can be measured. Alternatively, the sealing cone surface angle ø can be calculated by using the proportionality of corresponding sides of similar triangles and the cosine theorem of right triangles. The angle data measured or calculated are accurate.

Description

Technical Field

[0001] The invention relates to a solenoid valve manufacturing process, and in particular to a method for accurately measuring the angle of a sealing cone surface of a solenoid valve seat. Background Art

[0002] The valve seat of the automobile brake solenoid valve is small in size, and the valve seat sealing cone angle is a key design parameter. The valve seat sealing cone depth is shallow and the size is relatively small, so it is difficult to measure the valve seat angle value using traditional methods. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a method for accurately measuring the sealing cone angle of a solenoid valve seat.

[0004] The technical solution of the present invention:

[0005] A method for accurately measuring the angle of a solenoid valve seat sealing cone, the method comprising the following steps:

[0006] 1) Select two steel balls, one large and one small, where the radius of the large steel ball is R and the radius of the small steel ball is r.

[0007] 2) First place the valve seat on a workbench, then place the small steel ball and the large steel ball in the sealing cone surface of the valve seat in turn, and measure the height difference x between the center of the large steel ball and the center of the small steel ball.

[0008] 3) Magnify the parameters R, r, and x by n times, draw the valve seat sealing cone diagram, and measure the valve seat sealing cone angle ø.

[0009] In step 3), a drawing software is used to draw a diagram of the valve seat sealing cone.

[0010] A method for accurately measuring the angle of a solenoid valve seat sealing cone, the method comprising the following steps:

[0011] 1) Select two steel balls, one large and one small, where the radius of the large steel ball is R and the radius of the small steel ball is r.

[0012] 2) First place the valve seat on a workbench, then place the small steel ball and the large steel ball in the sealing cone surface of the valve seat in turn, and measure the height difference x between the center of the large steel ball and the center of the small steel ball.

[0013] 3) According to the formula: sinø / 2=(Rr) / x; calculate the valve seat sealing cone angle ø.

[0014] In step 2), take a plane above the valve seat as the reference plane, place a small steel ball in the valve seat sealing cone, measure and record the distance from the reference plane to the small steel ball as l, place a large steel ball in the valve seat sealing cone, measure and record the distance from the reference plane to the large steel ball as L; x = (L+R)-(l+r).

[0015] The advantages of the present invention are reasonable design and ingenious conception. Two steel balls, one large and one small, are introduced during measurement. When the steel balls are placed in the valve seat sealing cone surface, they are tangent to the valve seat sealing cone surface. In this way, after the height difference between the centers of the two steel balls is measured, a valve seat sealing cone surface diagram can be drawn, and the sealing cone surface angle ø can be measured, or the sealing cone surface angle ø can be calculated by using the proportionality of corresponding sides of similar triangles and the cosine theorem of right triangles; the angle data measured or calculated are accurate.
