Description
Technical field
The assembly tooling when water pressure test, in particular to a kind of thin-wall case are carried out the present invention relates to a kind of pair of thin-wall case
Carry out what the wedge ring on seal plug was assembled after seal plug is set on the port of thin-wall case when carrying out the water pressure test
Assembly tooling and assembly method.
Background technique
Thin-wall case after processing is completed, need to carry out it water pressure test of 20 megapascal, to detect whether shell can go out
Now leakage, damage or other abnormal phenomenon.Since the thin-wall case is tubing products, one end is end socket, when hydraulic pressure bulge test, is needed
Seal plug is set in the other end of shell, to close the inner cavity of the shell, since the inner wall of thin-wall case is shiny surface, no
Screw thread can be set, the common plug that is threadedly coupled can not be implemented, the corresponding seal plug of Site Design, Lai Shixian plug with
The connection of shell is provided with three grooves on the lateral surface of seal plug, is each equipped in the twice groove of inside O-shaped close
Plug equipped with two sealing rings is assembled on the another port of shell, then again passes through copper assembly wedge ring by seal
The wedge ring installation opening reserved on plug, is inserted between plug and the another port inner sidewall of shell, makes the another of plug and shell
Single port forms the tensioner cooperation of wedge shape, the reliable sealing of plug when guaranteeing the shell intracorporal high water pressure test.Wedge ring is by copper
The flat copper band of matter is inserted into the annular seal body formed after the third road groove of plug, 1 millimeter of the head thickness of flat copper band,
Width is 1.5 millimeters, middle section with a thickness of 1.36 millimeters, the width of middle section is 3 millimeters, and length is 244 millimeters, flat
The length of flat copper strips is greater than the perimeter of the third road groove on plug, therefore, flat copper band is packed into both ends after plug one encloses
Have a margin；But since flat copper bandwidth is narrow, thickness is thin, and intubating length is long, how to pass through flat copper band on plug
The installation opening being connected to third road groove be inserted into third road groove, be fitted close plug and thin-walled degree of lip-rounding wedgewise,
To resist high hydraulic pressure, becomes scene and be badly in need of the problem to be solved.
