Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Such as Fig. 1, the present invention proposes a kind of hot-water heating pipe connections of convenient disassembly, including connection main body 5, and its two ends difference is embedding
Equipped with sealing ring 4；Two transition sleeves 3, its one end is fixed in the end of connection main body 5, and is offseted with sealing ring 4；The other end is set
There are some fixed claws 304；Two locking nuts 2, gather fixed claw 304 when it is with 3 thread connection of transition sleeve.
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 to realize sealed effect between transition sleeve 3 and connection main body 5.
Such as Fig. 2, the two ends of above-mentioned connection main body 5 are respectively equipped with a link slot 501, and the inwall of link slot 501 is provided with
Annular groove 502；One end of above-mentioned transition sleeve 3 is provided with the clamping section 302 in insertion link slot 501, the cylindrical side wall of clamping section 302
Provided with the hangnail 303 with the clamping of 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 be along the axially arranged multiple tracks for connecting 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 baffle plates 301 on the cylindrical side wall of above-mentioned clamping section 302, spin-ended baffle plate 301 is along above-mentioned transition
The axis extension of set 3, and spin-ended baffle plate 301 is uniform around the axis of transition sleeve 3；The inwall of above-mentioned link slot 501 be provided with
The baffle plate slot 505 (as shown in Figure 3) that the spin-ended grafting of baffle plate 301 coordinates.When rotational lock 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 is connected.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 above-mentioned transition sleeve 3 away from one end of above-mentioned clamping section 302, and fixed claw 304 encloses
Axis around transition sleeve 3 is uniform；The free end of each fixed claw 304 is towards the side of the axis of transition sleeve 3 provided with the sharp block of clamping
305.When fixed claw 304 is gathered, the wedge angle seamed edge of the sharp block 305 of clamping compresses PPR pipe 1, realizes between transition sleeve 3 and PPR pipe 1
Fixation.
Border is provided with ring 201 is gathered on the madial wall of above-mentioned locking nut 2, 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
Individual fixed claw 304 is gathered to the outer surface of 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 outline of above-mentioned connection main body 5 and the cross section of locking nut 2 is regular hexagon.The structure facilitates locking nut
2 rotation, is easy to dismounting.
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.Now, annular groove 502 and the first seal structures of formation of hangnail 303 (labyrinth seal), transition sleeve 3 and sealing
Circle 4 forms the second seal structures, and two sealed structures cooperate, and prevents water in PPR pipe 1 from connection main body 5 and transition
Leaked between set 3.
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.In the presence of ring 201 is gathered, each is consolidated
Determine pawl 304 to the outer surface of PPR pipe 1 to gather, the sharp block 305 of clamping is compressed the outer surface of PPR pipe 1, 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 occurs compression；Stretched after deformation
Contracting sealing ring 6 can block the gap between PPR pipe 1 and transition sleeve 3, prevent current from leaking.
The hot-water heating pipe connections of convenient disassembly of the present invention, convenient disassembly, good airproof performance.Rotated by general tool
Locking nut 2, you can complete the fractionation and connection work between the present invention and PPR pipe 1.Formed by hangnail 303 and annular groove 502
First of labyrinth seal structure, by sealing ring 4 and the second seal structures of formation of transition sleeve 3, two sealed structures can be protected
Demonstrate,prove the sealing of the present invention, it is to avoid the water in PPR pipe 1 leaks between connection main body 5 and transition sleeve 3.Simultaneously as sealing ring
4 do not contact directly with PPR pipe 1, can slow down aging, improve its service life.In addition, PPR pipe 1 is expanded after heated,
Its own micro gap between transition sleeve 3 can be blocked；Again can be by PPR pipe 1 and transition sleeve 3 by flexible seal ring 6
Between gap block completely.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
