The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Such as Fig. 1, the utility model proposes a kind of connector for hot-water heating PPR pipe, including connection main body 5, its both ends point Qian Zhuanyou not sealing ring 4;Two transition sleeves 3, its one end are fixed in the end of connection main body 5, and offset with sealing ring 4;It is another End is equipped with some fixed claws 304;Two locking nuts 2, it during 3 thread connection of transition sleeve with gathering fixed claw 304.
Above-mentioned sealing ring 4 stretches out the end of above-mentioned connection main body 5.As shown in Figure 1, when transition sleeve 3 is fixed with being connected main body 5 When, the sealing ring 4 of stretching can be compressed, makes the effect that sealing is realized between transition sleeve 3 and connection main body 5.
Such as Fig. 2, the both ends of above-mentioned connection main body 5 are respectively equipped with a link slot 501, and the inner wall of link slot 501 is equipped with Annular groove 502;One end of above-mentioned transition sleeve 3 is equipped with the clamping section 302 in insertion link slot 501, is clamped on the cylindrical side wall of section 302 Equipped with the hangnail 303 being clamped with annular groove 502.Link slot 501 and clamping section 302 may be selected as shown in Figure 1, 2 with the conical surface Frustum cone structure.Annular groove 502 can set multiple tracks along the axial of connection main body 5.Clamping engagement between annular groove 502 and hangnail 303 can Labyrinth seal structure is formed before sealing ring 4, further prevents the current in PPR pipe 1 from leaking.
It is additionally provided with some spin-ended baffles 301 on the cylindrical side wall of above-mentioned clamping section 302, spin-ended baffle 301 is along above-mentioned transition The axis extension of set 3, and spin-ended baffle 301 is evenly distributed with around the axis of transition sleeve 3;The inner wall of above-mentioned link slot 501 be equipped with The mating baffle slot 505 (as shown in Figure 3) of spin-ended baffle 301.When rotation locking nut 2 is dismounted, spin-ended gear Plate 301 can prevent from rotating between transition sleeve 3 and connection main body 5.
The bottom of each above-mentioned link slot 501 is equipped with a round table-like guide table 504, and two link slots 501 pass through Water hole 503 between two guide tables 504 connects.The port sleeve of PPR pipe 1 is realized to PPR in guide table 504 The positioning of pipe 1.As shown in Figure 1, being connected between two PPR pipes 1 by water hole 503, water is set smoothly to circulate.
Such as Fig. 1, above-mentioned fixed claw 304 is placed in one end that above-mentioned transition sleeve 3 deviates from above-mentioned clamping section 302, and fixed claw 304 encloses Axis around transition sleeve 3 is evenly distributed with;The free end of each fixed claw 304 is equipped with the sharp block of clamping towards the side of 3 axis of transition sleeve 305.When fixed claw 304 is gathered, the wedge angle seamed edge for clamping sharp block 305 compresses PPR pipe 1, realizes between transition sleeve 3 and PPR pipe 1 Fixation.
Border, which is equipped with, on the madial wall of above-mentioned locking nut 2 gathers ring 201, and the longitudinal section for gathering ring 201 is triangle, and Female thread portion of the hypotenuse close to locking nut 2.When tightening locking nut 2, forced respectively by gathering ring 201 Gather the outer surface of a fixed claw 304 to PPR pipe 1.
A flexible seal ring 6 is additionally provided between above-mentioned fixed claw 304, flexible seal ring 6 and above-mentioned transition sleeve 3 are coaxial.
The outer contour of 2 cross section of above-mentioned connection main body 5 and locking nut is regular hexagon.The structure facilitates locking nut 2 rotation, it is easy to disassemble.
In use, first the clamping section 302 of two transition sleeves 3 is inserted into link slot 501, until hangnail 303 and annular groove 502 are connected together.At this time, annular groove 502 and hangnail 303 form the first seal structures (labyrinth seal), transition sleeve 3 with it is close Seal 4 forms the second seal structures, and two sealed structures cooperate, and prevents water in PPR pipe 1 from connection main body 5 and mistake Cross between covering 3 and leak.
Afterwards, PPR pipe 1 sequentially passes through the locking nut 2 unscrewed, the flexible seal ring being placed between fixed claw 304 6 and mistake Set is crossed, until sleeve is in the outside of guide table 504.Finally, locking nut 2 is tightened.Under the action of ring 201 is gathered, Ge Gegu The outer surface for determining pawl 304 to PPR pipe 1 is gathered, on the one hand make clamping point block 305 compress PPR pipe 1 outer surface, by transition sleeve 3 with Position between PPR pipe 1 is fixed;On the other hand, each fixed claw 304 extrudes flexible seal ring 6 when gathering, and makes flexible sealing Circle 6 is slid onto the root (junction of fixed claw 304 and transition sleeve 3) of fixed claw 304, and compression occurs;Stretched after deformation Contracting sealing ring 6 can block the gap between PPR pipe 1 and transition sleeve 3, prevent current from leaking.
Connector described in the utility model for hot-water heating PPR pipe, convenient for disassembly and assembly, good airproof performance.Pass through general tool Rotate locking nut 2, you can complete the fractionation and connection work between the utility model and PPR pipe 1.Pass through hangnail 303 and ring Groove 502 forms first of labyrinth seal structure, and the second seal structures, two seals knot are formed by sealing ring 4 and transition sleeve 3 Structure can ensure the leakproofness of the utility model, avoid the water in PPR pipe 1 from leaking between connection main body 5 and transition sleeve 3.Together When, since sealing ring 4 does not contact directly with PPR pipe 1, aging can be slowed down, improve its service life.In addition, PPR pipe 1 by Expanded after heat, its own micro gap between transition sleeve 3 can be blocked;Again can be by PPR by flexible seal ring 6 Gap between pipe 1 and transition sleeve 3 blocks completely.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model Protection domain within.
