Abstract
The invention provides an expansion coupling tee joint which comprises a first pipe fitting inserting port, a second pipe fitting inserting port and a third pipe fitting inserting port. The first pipe fitting inserting port and the third pipe fitting inserting port are perpendicular to the second pipe fitting inserting port and are located on an identical axis, the outer diameter of the third pipe fitting inserting port is smaller than the inner diameter of the first pipe fitting inserting port, and a sealing ring is arranged on the periphery of the third pipe fitting inserting port. Specifically, the sealing ring can be made of TPU and can also be made of silica gel. The expansion coupling tee joint is easy to mount and high in efficiency, and the problem that an existing tee joint cannot be mounted when water pipes cannot be moved is solved.
Description
Technical field
The present invention relates to pipe fitting field, relate 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 exceed the edge of another pipe fitting and cannot install.Existing solution is after sawed-off mounted pipe fitting; install straight-through at sawed-off place; 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 problem to be solved in the present invention, 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 in the time that pipe fitting cannot move.
The present invention 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.
Tool of the present invention has the following advantages: install simply, efficiency is high, good sealing effect.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of existing threeway.
Fig. 2 is the structural representation of threeway of the present invention.
Fig. 3 is the structural representation of a kind of threeway seal ring of the present invention.
Fig. 4 is the structural representation of another kind of threeway seal ring of the present invention.
Embodiment
Refer to Fig. 1 to shown in Fig. 4, below the present invention is described in detail.
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, in the time of application, the length (the 3rd pipe fitting joint socket 6 edges are to the shortest distance of the second pipe fitting joint socket 5 periphery) of the 3rd pipe fitting joint socket 6 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 ensure 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 well rear (after as PPR hot melt or after PVC gluing) of Job readiness, the first pipe fitting joint socket 4 is pushed up on 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 present invention 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 can play seal action as long as annular, and the cross section of seal ring 7 is 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 present invention 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.
The above mode of execution, it is preferred embodiments of the present invention, be not to limit the scope of the present invention, the equivalence of doing according to structure, feature and principle described in the present patent application the scope of the claims therefore all changes or modifies, and all should comprise in patent claim of the present invention.
