The front of step surface is clamped with the between outer land terrace of thread bush (2), outside the rear portion of semicircle positioning sleeve (6) interior step surface and thin-wall pipe
The step surface of side is clamped, and then semicircle positioning sleeve (6) is fixed and clamped with clip (8) component；Positioning clamps thread bush (2) handle
Six side parts of mouth (1) are connect until rubber gasket (4) deforms upon with spanner rotation behind portion flat (12).
Advantages of the present invention
One end of sealing ring with o is put into product endoporus by the present invention, and thin-wall pipe and group will be tested with hoop component
Clamping is fixed in tool after conjunction, then with auxiliary tool position clamp thread bush shank it is flat after with spanner rotation connect mouth front
Six side parts are until compressional deformation occurs for rubber pad, O-ring seal, cone angle, screw thread and the exerciser of the other end of tool
Upper part cone angle, screw-internal thread fit airtight connection require pressure and the Jie of Adjustment Tests device according to the test pressure of product drawing
Matter experiment proves that this thin-wall pipe suppresses leakage test tool and test method meets the test pressure requirement of product.Design essence
Ingeniously, simple in structure, easy to use, manufacturing cost is low, solves the problems, such as that thin-wall pipe suppresses leakage test.
