Description

A kind of hose pipe end blocks the device of leak test
Technical field
The present invention relates to the leak tests of tubing products, realize especially for soft pipe fitting (nylon tube, rubber tube etc.) quick Leak test is blocked, specifically a kind of hose pipe end blocks the device of leak test.
Background technique
Leak test is one of common procedure of tubing products, and leak test efficiency can be improved in quick blocking pipe end, simplifies leak test behaviour Make.
One end ventilation is blocked for one end that soft pipe fitting (nylon tube, rubber tube etc.) quick blocking leak test routinely uses Method, but pressure is slightly larger just to be will appear expansion or seals not tight situation, the purpose of pressure testing is not achieved, simultaneously because hose Physical characteristic will lead to leak test inconvenience.
Summary of the invention
The present invention is in order to not only fastly but also easily to soft pipe fitting (nylon tube, rubber tube etc.) quick blocking leak test, spy It is proposed that a kind of hose pipe end blocks the device of leak test.
The technical scheme is that, a kind of hose pipe end blocks the device of leak test, including test hose thus, tests soft One end of pipe blocks, it is characterised in that: the test hose other end is equipped with pipe end plugging device, and pipe end plugging device includes a gas Cylinder, cylinder is interior to be equipped with piston, and piston shaft extends outside cylinder, and test venthole is equipped in piston shaft;
It is additionally provided with drive end bearing bracket in the other end of cylinder, drive end bearing bracket screws in cylinder, and the end face of piston is ventilated equipped with corrugated Pipe tests venthole and the perforation of corrugated snorkel;
Silica gel sealing ring is provided in drive end bearing bracket, the assembly that corrugated snorkel forms test hose in silica gel sealing ring is closed System, test hose cover outside Bamboo-shaped snorkel, and test hose outer wall and silica gel sealing ring form sealing relationship;
The end face of cylinder is penetrated through into cylinder body is equipped with cylinder venthole;
Sealing ring is additionally provided between piston and cylinder inner wall.
Further improvement is that the clamping force of the cylinder is tested workpiece leak test gas pressure 2 times or more, silica gel Sealing ring hardness is 40-50A.
The utility model has the advantages that
The present invention is filled with compressed air into the cylinder venthole of cylinder when in use, and piston moves down, compressed silicone rubber sealing Circle, makes contracting silica gel sealing ring tightly wrap test hose and corrugated snorkel to form sealing state;Test venthole again Inflation carries out leak test test to hose, otherwise exits.
The configuration of the present invention is simple, use is safe, quick for the convenient test of hose, improves leak test efficiency, simplifies leak test Operation.
The clamping force of cylinder is recommended as tested pipe fitting leak test gas pressure 2 times or more, can guarantee to test piece in this way Clamping, will not because of 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.
Detailed description of the invention
Fig. 1 is front sectional view of the invention.
1 is cylinder in figure, and 2 be drive end bearing bracket, and 3 be sealing ring, and 4 be corrugated snorkel, and 5 be piston, and 6 be silica gel sealing Circle, 7 be piston shaft, and 8 be cylinder venthole, and 9 be test venthole, and 10 be test hose.
Specific embodiment
The present invention is as shown in Figure 1.
A kind of hose pipe end blocks the device of leak test, including test hose 10, and one end of test hose 10 blocks, tests soft 10 other end of pipe is equipped with pipe end plugging device, and pipe end plugging device includes a cylinder 1, is equipped with piston 5, piston shaft 7 in cylinder 1 Extend outside cylinder 1, test venthole 9 is equipped in piston shaft 7;
It is additionally provided with drive end bearing bracket 2 in the other end of cylinder 1, drive end bearing bracket rotation 2 enters in cylinder 1, and the end face of piston 3 is equipped with corrugated Snorkel 4, tests venthole 9 and corrugated snorkel 4 penetrates through;
Silica gel sealing ring 6 is provided in drive end bearing bracket 2, corrugated snorkel 4 forms the dress of test hose 10 in silica gel sealing ring 6 With relationship, 10 sets of test hose outside corrugated snorkel 4,10 outer wall of test hose and silica gel sealing ring 6 form sealing relationship;
The end face of cylinder 1 is penetrated through into cylinder body is equipped with cylinder venthole 8;
Sealing ring 3 is additionally provided between 1 inner wall of piston 4 and cylinder.
The clamping force of cylinder 1 is recommended as tested 10 leak test gas pressure 2 times or more of hose, can guarantee to test in this way The clamping of hose 10 will not recommend 40- because of the danger that leak test gas pressure is excessive and causes a departure from, 6 hardness of silica gel sealing ring 50A has been to be able to enough resilient seals.
