Fixture nut 22-4 uses fixture nut 22-4 by lid 21, base ring after the perforation on the second perforation 22-2 and extension board 21-4
22 lock together, water seal mouth 22-6 and semi-ring protrusion 21-5 engaging in base ring 22.
Basic principle: the 3 junction trickle water of first pipe 1 and second pipe of rupture, place spray of the water from rupture
Out, it is radial then, water can enter base ring 22 in water seal mouth 22-6 in, water be filled with gap completely cut off outside air into
Enter in pipeline, guarantee that the pressure inside and outside pipeline is consistent, avoids pressure difference from leading to the secondary rupture of pipeline junction, while water enters
Main body 2 has bigger impact force, and the sealing plate 21a of setting can both buffer water flow, with the flowing of water flow, sealing plate 21a-
2 can also rotate, and deformation occurs that 1 pipeline outer wall of first pipe and shell 21-1 inner wall are withstood in two sides by rubber layer 21a-1,
Carry out enclosure space.
Problems solved by the invention is during high force feed water, if verifying, the connection of low layer pipeline goes wrong, will
Pressure release, water can not be sent to high level, pressure testing again after needing first to safeguard, trouble of testing in layer in this way, using cloth etc.
Temporary plug, hydraulic pressure is higher when pressure testing, can break up tamper, not can solve this problem, and the present invention passes through above-mentioned component
Be combined with each other, the present invention mainly passes through lid 21, base ring 22 and sealing plate 21a etc., the first pipe 1 of interim package water outlet
With 3 junction of second pipe, pressure inside and outside the pipeline of junction is balanced, avoids the secondary rupture of pipeline, is completely cut off using water seal extraneous
Air while water flow sealed body, constantly buffers water flow, hydraulic pressure height is avoided to break through main body 2, can not send pressure, continue to test
Upper pipeline.
