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 endoporus 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 endoporus 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 endoporus leak test.
It is a kind of device using closure pipe end endoporus 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, the cylinder head extension of cylinder
To the pipe end of test piece, the pipe end inwall that silica gel sealing ring and test piece are wherein cased with cylinder head forms sealing structure
One, and by cylinder head outside nut compress silica gel sealing ring, be additionally provided with piston shaft in the cylinder body of cylinder, piston shaft passes through sealing ring
Sealing structure two is formed with the cylinder body of cylinder, runs through on piston shaft and is penetrated provided with passage one and cylinder；Respective cylinder on piston shaft
Head is additionally provided with passage two and the pipe of test piece and penetrated.
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 into the passage one of cylinder when in use, and piston shaft moves down, and passes through
The common compressed silicone rubber sealing ring of nut and cylinder, seals test piece and piston shaft, and sealing ring ensures cylinder normal work.Survey
The other end closure of trial work part, is filled with leak test compressed air into the pipe of test piece by passage two, reaches test piece
The purpose of leak test, after being completed, compressed air, silica gel sealing ring resilience, with test piece pipe end are discharged by passage two
Inwall frictional force disappear, sealing structure one takes out together with cylinder.
For the structure by blocking pipe end endoporus leak test, 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 sealing ring, and 3 be piston shaft, and 4 be silica gel sealing ring, and 5 be nut, and 6 be cylinder head, and A is to survey
Trial work part, B are passages one, and C is passage two.
Embodiment
The utility model as shown in figure 1,
A kind of device using closure pipe end endoporus leak test, include test piece A, test piece A one end closure（It is existing
Technology is not shown）, the pipe end of the test piece A other ends is provided with cylinder 1, and the cylinder head 6 of cylinder 1 extends to test piece A pipe end
Interior, the pipe end inwall that silica gel sealing ring 4 and test piece A are wherein cased with cylinder head 6 forms sealing structure one, and passes through cylinder head 6
Outer nut 5 compresses silica gel sealing ring 4, is additionally provided with piston shaft 3 in the cylinder body of cylinder 1, piston shaft 3 passes through sealing ring 2 and cylinder 1
Cylinder body form sealing structure two, run through penetrating on piston shaft 3 provided with the B of passage one and cylinder 1；Cylinder head 6 is corresponded on piston shaft 3
It is additionally provided with the C of passage two and test piece A pipe and penetrates.
Be filled with compressed air into the B of passage one of cylinder 1 when in use, piston shaft 3 moves down, by nut 5 with
The common compressed silicone rubber sealing ring 4 of cylinder 1, seals test piece A and piston shaft 3, and sealing ring 2 ensures cylinder normal work.Survey
Trial work part A other end closure, is filled with leak test compressed air into test piece A pipe by the C of passage two, reaches test work
The purpose of part A leak tests, after being completed, compressed air, the resilience of silica gel sealing ring 4, with test piece are discharged by the C of passage two
The inwall frictional force of A pipe ends disappears, and sealing structure one is taken out together with cylinder 1.
