Abstract
A kind of device using closure pipe end outer wall leak test of the utility model, one end closure of test piece, the pipe end of the test piece other end are provided with cylinder, and the piston boit of cylinder extends outside cylinder, and test passage is provided with piston boit；Insertion is provided with cylinder passage in cylinder extroversion cylinder；The other end of cylinder is provided with drive end bearing bracket, and silica gel sealing ring is provided with drive end bearing bracket, is equipped with silica gel sealing ring with test piece outer wall；Test the endoporus insertion of passage and test piece；Sealing ring is provided between cylinder and piston.The utility model is filled with compressed air in the ventilation cylinder passage to cylinder when in use, piston moves down, compressed silicone rubber sealing ring, the outer wall of test piece is tightly wrapped using silica gel sealing ring, then leak test compressed air is filled with to test passage, reaches the purpose by using closure test piece pipe end outer wall leak test, after being completed, otherwise test piece is exited, the structure blocks leak test by test piece pipe end outer wall, and simple and fast is convenient.
Description
Technical field
It the utility model is related to the leak test of tubing products, specifically a kind of device using closure pipe end outer wall leak test.
Background technology
Leak test is one of common procedure of tubing products, and quick blocking pipe end can improve leak test efficiency, simplifies leak test behaviour
Make.
For intermediate diameter（Internal diameter φ 16）One end that the leak test of pipe fitting quick blocking pipe end outer wall above routinely uses
The method for blocking one end ventilation, but pressure is slightly larger just to be occurred expansion or seals not tight situation, does not reach the mesh of pressure testing
's.
The content of the invention
The utility model is in order to not only soon but also easily to intermediate diameter（Internal diameter φ 16）Pipe fitting above carries out leak test,
Spy proposes a kind of device using closure pipe end outer wall leak test.
It is a kind of device using closure pipe end outer wall leak test for this technical solution of the utility model, including test work
Part, one end closure of test piece, it is characterised in that：The pipe end of the test piece other end is provided with cylinder, and the piston boit of cylinder prolongs
Stretch out outside cylinder, and test passage is provided with piston boit；
Insertion is provided with cylinder passage in cylinder extroversion cylinder；
The other end of cylinder is provided with drive end bearing bracket, silica gel sealing ring is provided with drive end bearing bracket, silica gel sealing ring is interior and tests work
Part outer wall is equipped with；
Test the endoporus insertion of passage and test piece；
Sealing ring one, sealing ring two are provided between cylinder and piston.
Further improve is：The clamping force of cylinder is to be tested more than 2 times of pipe fitting leak test gas pressure, silica gel sealing ring
Hardness recommends 40-50A.
Beneficial effect：
The utility model is filled with compressed air in the ventilation cylinder passage to cylinder when in use, and piston moves down, pressure
Contracting silica gel sealing ring, the outer wall of test piece is tightly wrapped using silica gel sealing ring, then leak test is filled with to test passage
Compressed air, reach the purpose by using closure test piece pipe end outer wall leak test, after being completed, otherwise exit test work
Part.
Sealing ring ensures cylinder normal work.
The structure blocks leak test by test piece pipe end outer wall, and simple and fast is convenient.
The clamping force of cylinder is recommended as being tested more than 2 times of pipe fitting leak test gas pressure, can so ensure to test piece
Clamping, will not because the danger that leak test gas pressure is excessive and causes a departure from, silica gel sealing ring hardness recommend 40-50A be for
There can be enough resilient seals.
Brief description of the drawings
Fig. 1 is the pipe end constructions operating diagram of the utility model test piece other end.
1 is cylinder in figure, and 2 be drive end bearing bracket, and 3 be sealing ring one, and 4 be piston, and 5 be sealing ring two, and 6 be silica gel sealing ring, 7
It is cylinder passage, 8 be test passage, and 9 be test piece.
Embodiment
The utility model as shown in figure 1,
A kind of device using closure pipe end outer wall leak test, including test piece 9, one end closure of test piece 9, test
The pipe end of the other end of workpiece 9 is provided with cylinder 1, and the piston boit 4 of cylinder 1 extends outside cylinder 1, and test is provided with piston boit 4
Passage 8；
Insertion is provided with cylinder passage 7 in the export-oriented cylinder 1 of cylinder 1；
The other end of cylinder 1 is provided with drive end bearing bracket 2, silica gel sealing ring 4 is provided with drive end bearing bracket 2, silica gel sealing ring 4 is interior and surveys
The outer wall of trial work part 9 is equipped with；
Test the endoporus insertion of passage 8 and test piece 9；
Sealing ring 1, sealing ring 25 are provided between cylinder 1 and piston 4.
The clamping force of cylinder 1 is recommended as more than 2 times of 9 leak test gas pressure of tested workpiece, can so ensure to test
The clamping of workpiece 9,40- will not be recommended because the danger that leak test gas pressure is excessive and causes a departure from, the hardness of silica gel sealing ring 4
50A is to be able to enough resilient seals.
Claims (2)
