Description
Technical field
The leak test of tubing products is the utility model is related to, especially for soft pipe fitting（Nylon tube, rubber tube etc.）Realize
Quick blocking leak test, specifically a kind of device of flexible pipe pipe end closure 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 soft pipe fitting（Nylon tube, rubber tube etc.）One end that quick blocking leak test routinely uses blocks one end ventilation
Method, but pressure is slightly larger just to be occurred expansion or seals not tight situation, does not reach the purpose of pressure testing, simultaneously because flexible pipe
Physical characteristic leak test can be caused inconvenient.
The content of the invention
The utility model is in order to not only soon but also easily to soft pipe fitting（Nylon tube, rubber tube etc.）Quick blocking is tried
Leakage, spy propose a kind of device of flexible pipe pipe end closure leak test.
It is a kind of device of flexible pipe pipe end closure leak test for this technical solution of the utility model, including test hose, survey
Try one end closure of flexible pipe, it is characterised in that：The test hose other end is provided with pipe end plugging device, and pipe end plugging device includes one
Individual cylinder, cylinder is interior to be provided with piston, and piston shaft extends outside cylinder, and test passage is provided with piston shaft；
Drive end bearing bracket is additionally provided with the other end of cylinder, drive end bearing bracket is screwed in cylinder, and the end face of piston is provided with corrugated
Breather pipe, test passage and the insertion of corrugated breather pipe；
Silica gel sealing ring is provided with drive end bearing bracket, corrugated breather pipe forms the assembling of test hose in silica gel sealing ring
Relation, test hose are enclosed on outside Bamboo-shaped breather pipe, and test hose outer wall and silica gel sealing ring form sealing relationship；
The end face of cylinder penetrates into cylinder body is provided with cylinder passage；
Sealing ring is additionally provided between piston and cylinder inner wall.
Further improve is：The clamping force of the cylinder is to be tested more than 2 times of workpiece leak test gas pressure, silica gel
Sealing ring hardness is 40-50A.
Beneficial effect：
The utility model is filled with compressed air into the cylinder passage of cylinder when in use, and piston moves down, compression
Silica gel sealing ring, contracting silica gel sealing ring is set tightly to wrap to form sealing state by test hose and corrugated breather pipe；Test
Passage is reinflated to carry out leak test test to flexible pipe, otherwise exits.
The utility model is simple in construction, safe to use, quick for the convenient test of flexible pipe, improves leak test efficiency, simplifies
Leak test operates.
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
The utility model is as shown in Figure 1.
1 is cylinder in figure, and 2 be drive end bearing bracket, and 3 be sealing ring, and 4 be corrugated breather pipe, and 5 be piston, and 6 be silica gel sealing
Circle, 7 be piston shaft, and 8 be cylinder passage, and 9 be test passage, and 10 be test hose.
Embodiment
The utility model is as shown in Figure 1.
A kind of device of flexible pipe pipe end closure leak test, including test hose 10, one end closure of test hose 10, test are soft
The other end of pipe 10 is provided with pipe end plugging device, and pipe end plugging device includes a cylinder 1, piston 5, piston shaft 7 are provided with cylinder 1
Extend outside cylinder 1, test passage 9 is provided with piston shaft 7；
Drive end bearing bracket 2 is additionally provided with the other end of cylinder 1, drive end bearing bracket rotation 2 enters in cylinder 1, and the end face of piston 3 is provided with ripple
Line shape breather pipe 4, tests passage 9 and corrugated breather pipe 4 penetrates；
Silica gel sealing ring 6 is provided with drive end bearing bracket 2, corrugated breather pipe 4 forms test hose 10 in silica gel sealing ring 6
Assembly relation, test hose 10 is enclosed on outside corrugated breather pipe 4, and the outer wall of test hose 10 and silica gel sealing ring 6 form sealing
Relation；
The end face of cylinder 1 penetrates into cylinder body is provided with cylinder passage 8；
Sealing ring 3 is additionally provided between piston 4 and the inwall of cylinder 1.
The clamping force of cylinder 1 is recommended as more than 2 times of 10 leak test gas pressure of tested flexible pipe, can so ensure to test
The clamping of flexible pipe 10,40- 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 6
50A is to be able to enough resilient seals.
