The service condition of the pvc pipe is as follows: when being linked and packed, the tubing that needs are connected, i.e. and the first tube body 1 and second The port of tube body 2 is close to flush, and then covers upper right connector sleeve 4 in the right end of the first tube body 1 and clogs in seal groove 93 close Then upper right connector sleeve 42 and bottom right connector sleeve 43 are locked on the first tube body 1 by seal by locking nut 91；? Left connector sleeve 3 and the fill plug seal circle in seal groove 93 are put on the left end of two tube bodies 2, are also clogged in interior closure gasket groove 94 Sealing ring, then outer seal sleeve 5 is inserted between left annular groove 31 and right annular groove 41, finally by left connector sleeve 34 direction of connector sleeve to the right Push-tight, determines that outer seal sleeve 5 is completed after fixing, and upper reinforcing rod 95 is inserted into upper reinforced hole 81 and is tightened, by lower reinforcing rod 96 It is inserted into lower reinforced hole 82 and tightens, be rotated further by locking nut 91 for upper left connector sleeve 32 and lower-left connector sleeve 33 and be fixed on second On tube body 2, so that left connector sleeve 3, right connector sleeve 4 and outer seal sleeve 5 complete this connection of the first tube body 1 and second body of rod 2, and Form inside and outside two layers of Hermetical connecting structure；When needing to overhaul and replacing tubing, it is only necessary to unscrew locking nut 91, upper reinforcing rod 95 and lower reinforcing rod 96, left connector sleeve 3 and right connector sleeve 4 under disassembly.

By the setting of outer seal sleeve 5, left connector sleeve 3, right connector sleeve 4, seal groove 93, the sealed connection of outer layer is formed Structure；By the lower sealing plate 710 of the first upper sealing panel 705, first, the lower sealing plate 610 of the second upper sealing panel 605, second, interior close The setting of seal ring slot 94 forms the Hermetical connecting structure of internal layer, effectively improves the sealing performance of tubing, and the sealing of internal layer connects Binding structure is set by the lower push plate 709 of push plate 704, first on the first upper plug head 702, the first lower end cap 707, spring 92, first Set, realize the adjustability of 710 position of sealing plate under the first upper sealing panel 705, first, by the second upper plug head 602, second The setting of the lower push plate 609 of push plate 604, second, realizes the second upper sealing panel 605, second on lower end cap 607, spring 92, second The adjustability of lower 610 position of sealing plate, after long-term use the distance between left connector sleeve 3 and right connector sleeve 4 broaden cause it is close Envelope property decline when, spring 92 exert a force so that the first upper sealing panel 705 be mutually close to the second upper sealing panel 605 it is close, under first Sealing plate 710 be mutually close to the second lower sealing plate 610 it is close, to ensure that the sealing performance of internal layer Hermetical connecting structure； By turning the first upper plug head 702, the first lower end cap 707, the second upper plug head 602, the second lower end cap 607, so that adjustment spring Internal pressure, so that regulating seal property, also facilitates the dismounting for completing spring.

As shown in Figure 8, it is overhauled in tubing, tubing occurs and needs replacing, it, can be with but when the tubing deficiency of required size By equally covering left connector sleeve 3 in the left side of smaller second tubing 2 of tubing bore, but can be corresponding in left connector sleeve 3 Filling size is greater than the sealing ring in left side in seal groove 93, so that it is guaranteed that left connector sleeve 3, right connector sleeve 4 and outer seal sleeve 5 connect The stability and leakproofness connect strives for time enough to replace the tubing of normal size.And even if not clogging larger sized Sealing ring can also temporarily guarantee the leakproofness of junction by the Hermetical connecting structure of internal layer.

The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
