Abstract
The utility model provides a three-way expansion joint. The three-way expansion joint comprises a first pipe fitting socket, a second pipe fitting socket and a third pipe fitting socket, wherein the first pipe fitting socket and the third pipe fitting socket are perpendicular to the second pipe fitting socket, the first pipe fitting socket and the third pipe fitting socket are on the same axis, the outer diameter of the third pipe fitting socket is smaller than the inner diameter of the first pipe fitting socket, and a sealing ring is arranged on the outer periphery of the third pipe fitting socket. Specifically, the sealing ring can be a TPU (thermoplastic polyurethane) sealing ring and can also be a silica gel sealing ring. The three-way expansion joint provided by the utility model has the advantages that the three-way expansion joint is simple to install, the efficiency is high and the problem that the existing three-way joint cannot be installed if a water pipe cannot be moved is solved.
Description
Technical field
The utility model relates to pipe fitting field, relates in particular to a kind of slip joint threeway.
Background technique
As shown in Figure 1, existing threeway is all to have three pipe fitting joint socket, and one end of a pipe fitting joint socket 1, two pipe fitting joint socket 2 and 3, three pipe fitting joint socket of three pipe fitting joint socket all connects together, internal run-through, and the other end opening is for connection pipe fitting.Existing problem is, in some places (as will be changed diversion and pipe fitting height on pipe fitting) want two pipe fittings that are connected a pipe fitting joint socket 1 and three pipe fitting joint socket 3 to fix, after a pipe fitting joint socket 1 or three pipe fitting joint socket 3 are connected with one of them pipe fitting, another one pipe fitting joint socket will surpass the edge of another pipe fitting and cannot install.Existing solution be mounted pipe fitting is sawed-off after; at sawed-off place, install straight-through; then after threeway is installed, will lead directly to and connect again; not only waste time and energy; and the position that pipe fitting connects also will be just; often can pipe fitting stay oversize and dress is not entered or too short making straight-throughly has gap and leak, success rate is extremely low.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of slip joint threeway, and trouble, the problem that success rate is not high are installed while solving existing threeway diversion when pipe fitting cannot move.
The utility model is achieved in that
A kind of slip joint threeway, comprise the first pipe fitting joint socket, the second pipe fitting joint socket and the 3rd pipe fitting joint socket, the first pipe fitting joint socket is mutually vertical with the second pipe fitting joint socket with the 3rd pipe fitting joint socket, the first pipe fitting joint socket and the 3rd pipe fitting joint socket are in same axis, the external diameter of the 3rd described pipe fitting joint socket is less than the internal diameter of the first pipe fitting joint socket, and described the 3rd pipe fitting joint socket periphery is provided with seal ring.
Further, described seal ring is hot body glue (TPU).
Further, described seal ring is silica gel sealing ring.
Further, the first described pipe fitting joint socket, the second pipe fitting joint socket and the 3rd pipe fitting joint socket are PPR pipe fitting joint socket.
Further, the first described pipe fitting joint socket, the second pipe fitting joint socket and the 3rd pipe fitting joint socket are pvc pipe part joint socket.
Further, described seal ring is annulated column shape.
Further, described seal ring surface is provided with the groove around seal ring.
Further, the cross section of described groove is square.
Further, the cross section of described groove is triangle.
Further, the internal diameter of the first described pipe fitting joint socket or the second pipe fitting joint socket is 20cm, 25 cm, 32 cm, 40 cm, 50 cm, 63 cm, 75 cm, 90 cm, 110 cm, 160cm.
The utlity model has following advantage: install simply, efficiency is high, good sealing effect.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the structural representation of existing threeway.
Fig. 2 is the structural representation of threeway of the present utility model.
Fig. 3 is the structural representation of a kind of threeway seal ring of the present utility model.
Fig. 4 is the structural representation of another kind of threeway seal ring of the present utility model.
Embodiment
Refer to Fig. 1 to shown in Fig. 4, below will be elaborated to the utility model.
A kind of slip joint threeway, comprise the first pipe fitting joint socket 4, the second pipe fitting joint socket 5 and the 3rd pipe fitting joint socket 6, the first pipe fitting joint socket 4 is mutually vertical with the second pipe fitting joint socket 5 with the 3rd pipe fitting joint socket 6, the first pipe fitting joint socket 4 and the 3rd pipe fitting joint socket 6 are in same axis, the external diameter of the 3rd pipe fitting joint socket 6 is less than the internal diameter of the first pipe fitting joint socket 4, and the 3rd pipe fitting joint socket 6 peripheries are provided with seal ring 7.Specifically, when application, the length of the 3rd pipe fitting joint socket 6 (the 3rd pipe fitting joint socket 6 edges are to the shortest distance of the second pipe fitting joint socket 5 periphery) is greater than the first pipe fitting joint socket 4, is preferably double length.Seal ring 7 is selected soft seal ring, is preferably hot body glue (TPU), or silica gel sealing ring, can guarantee well the sealing of pipe fitting.The 3rd pipe fitting joint socket 6 is inserted into a wherein inside pipe fitting of the pipe fitting that will connect together with seal ring 7, and then the first pipe fitting joint socket 4 is moved on on an other root canal orifice of the pipe fitting that will connect, connecting Job readiness well rear (after as PPR hot melt or after PVC gluing), by the first pipe fitting joint socket 4 top to the mouth of pipe of an other pipe fitting of the pipe fitting that will connect, now the 3rd pipe fitting joint socket 6 can be slightly away from wherein of the pipe fitting that will connect, but because the 3rd pipe fitting joint socket 6 length are longer, the 3rd pipe fitting joint socket 6 is still in sealing state, and situation about can not leak.
Described above, the utility model can be used for PPR pipe fitting or pvc pipe part, the first pipe fitting joint socket 4, the second pipe fitting joint socket 5 and the 3rd pipe fitting joint socket 6 are PPR pipe fitting joint socket, or the first pipe fitting joint socket 4, the second pipe fitting joint socket 5 and the 3rd pipe fitting joint socket 6 are pvc pipe part joint socket.
Seal ring 7 so long as annular can play seal action, the cross section of seal ring 7 be circular, for further enhanced leaktightness effect, seal ring 7 is annulated column shape, preferably, seal ring 7 surfaces are provided with the groove 70 around seal ring, have the situation that groove can adapt to more pipe fitting.Common, the cross section of groove 70 is square (as shown in Figure 3), the cross section of groove 70 is triangle (as shown in Figure 4).The utility model can be used for common family's water pipe connection area, and the internal diameter of the first pipe fitting joint socket 4 or the second pipe fitting joint socket 5 is common 20cm, 25 cm, 32 cm, 40 cm, 50 cm, 63 cm, 75 cm, 90 cm, 110 cm, 160cm.
