If the both sides of the conical surface of shut-off valve and the conical surface of main body are not parallel, judge that shut-off valve is unqualified.
If one side in the both sides of the conical surface of shut-off valve and the conical surface of main body are not parallel, judge that shut-off valve is unqualified.
It is illustrated below with detecting 3/8 shut-off valve and 1/4 shut-off valve.
The detection method of 3/8 shut-off valve:
A. it chooses detection device according to the shut-off valve specification that need to be detected first and corresponds to end；3/8 shut-off valve is such as detected, then is chosen
The left end of detection device；
It b. will be in the central axis of the centre bore of 3/8 shut-off valve insertion main body and by the conical surface of the conical surface of 3/8 shut-off valve and main body
It is engaged；
C. the conical surface of the centre bore of shut-off valve and the mated condition of central axis of main body and the conical surface of shut-off valve and main body is observed
Mated condition, if there is any one in following three situation, shut-off valve is unqualified:
The centre bore of shut-off valve cannot be inserted into the central axis of main body；
The conical surface of shut-off valve and the conical surface of main body cannot be engaged；
Two sides of the conical surface of shut-off valve and the conical surface of main body are not parallel；
One side in the both sides of the conical surface of shut-off valve and the conical surface of main body are not parallel.
The detection method of 1/4 shut-off valve:
When whether 1/4 shut-off valve of detection is qualified, the central axis of 1/4 shut-off valve alignment detection means is slightly firmly pushed, it will
The corresponding central axis of 3/8 shut-off valve of outside is pressed onto bottom, to expose the corresponding central axis of 1/4 shut-off valve of the inside, then presses 3/8 section
Only the detection method of valve is detected.
The detection method of 5/8 shut-off valve is as the detection method of 3/8 shut-off valve, the detection method of 1/2 shut-off valve and 1/4
The detection method of shut-off valve is the same.
Above specific embodiment is only to the design illustrated the present invention, and those skilled in the art are in this hair
Various deformation and variation can be made under bright design, these deformations and variation are included within protection scope of the present invention.
