Description

Composite water pipe
Technical field
It the utility model is related to a kind of sewer pipe, and in particular to a kind of composite water pipe.
Background technology
In the prior art, assembled mutually by screw thread between sewer pipe, although its junction can seal, herein Intensity be minimum in whole pipeline, once pipeline pressure is big, or using long afterwards, crack will be produced in junction, gone out The problem of existing aging leak.Therefore, it is necessary to which maintenance personal comes to repair after Pipeline damage, pipeline can not use during this, give The life of people is made troubles.Furthermore sewer pipe and its easily blocking, it is difficult dredging after blocking, it is necessary to which the pipeline of specialty is repaiied Science and engineering can just complete repairs, and very lose time and add daily expenses.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of composite water pipe, using dual-protection structure, ensures Pipeline occurs without seepy question, increases the sealability of junction, increases pipeline service life, and with the work(for blocking dredging Energy.
The utility model is achieved through the following technical solutions:A kind of composite water pipe, including the first connecting tube, second Connecting tube and an intermediate connector, intermediate connector centre have an annular seal space, the both ends point of the intermediate connector A connecting portion is not provided with, and a screw, first connecting tube and the second connecting tube are provided among the connecting portion Outer wall be provided with external screw thread, first connecting tube and the second connecting tube are by being threaded into screw and together It is inserted into the annular seal space inside intermediate connector, the opposite face of first connecting tube and the second connecting tube is tightly connected, institute State and a negative pressure device is mounted in the first connecting tube or the second connecting tube.
Preferably, being provided with first negative pressure hole in first connecting tube, the centre of the negative pressure hole of face first connects The second negative pressure hole is provided with fitting, a piece negative pressure connecting tube is set through the first negative pressure hole and the second negative pressure hole, it is described negative The outboard end of connecting tube and the air inlet of negative pressure device is pressed to connect.
Preferably, the negative pressure device includes a negative pressure pump, it is fixedly installed in centre by the connecting portion at both ends The outside of connector, the screw of locking is provided with connecting portion.
Preferably, first connecting tube is provided with a department of assembly with respect to second connecting tube one end, department of assembly and the It is threadedly coupled between two connecting tubes.
Preferably, the outer wrap of the negative pressure connecting tube has one layer of rubber sealant.
The beneficial effects of the utility model are:The utility model is simple in construction, can effectively realize to the close of connecting water pipe Envelope connection, increase the sealability of junction, prevent junction because of the big explosion of pressure and the problem of leak occur, it is dual close Envelope, increase safety in utilization, and possess the function of blocking dredging.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Coding is respectively in figure:1 is negative pressure connecting tube, and 2 be negative pressure pump, and 3 be department of assembly, and 4 be the second connecting tube, and 5 be close Chamber is sealed, 6 be intermediate connector, and 7 be the first connecting tube, and 8 be connecting portion.
Embodiment
As shown in figure 1, this composite water pipe, including the first connecting tube 7, the second connecting tube 4 and an intermediate connector 6, There is an annular seal space 5 among intermediate connector 6, the both ends of intermediate connector 6 are respectively arranged with a connecting portion 8, connecting portion 8 Centre is provided with a screw, and the outer wall of the first connecting tube 7 and the second connecting tube 4 is provided with external screw thread, the first connecting tube 7 And second connecting tube 4 by being threaded into screw and in the annular seal space that is inserted into together inside intermediate connector, The opposite face of one connecting tube 7 and the second connecting tube 4 is tightly connected, and one is mounted in the first connecting tube 7 or the second connecting tube 4 Individual negative pressure device.
In the present embodiment, first negative pressure hole is provided with the first connecting tube 7, is connected among the negative pressure hole of face first The second negative pressure hole is provided with part, a piece negative pressure connecting tube 1, negative pressure connection are set through the first negative pressure hole and the second negative pressure hole The outboard end of pipe and the air inlet of negative pressure device connect.Negative pressure device includes a negative pressure pump 2, and it is consolidated by the connecting portion at both ends Dingan County is loaded on the outside of intermediate connector 6, and the screw of locking is provided with connecting portion.We pass through the suction of negative pressure pump 2, profit With negative pressure connecting tube 1, a suction is produced to whole pipeline inside, if pipeline interlude blocks, then this strand of suction can By slack and undisciplined at blocking or conducting, to complete the purpose of Quick dredging.
Wherein, 7 relative one end of second connecting tube 4 of the first connecting tube is provided with a department of assembly 3, and department of assembly 3 and second connects It is threadedly coupled between adapter 4.Because the first connecting tube 7 and the outside of the second connecting tube 4 are provided with external screw thread, it connects with whole centre It is once sealing between fitting 6, furthermore, sealed between the first connecting tube 7 and the second connecting tube 4 further through the secondary connection of screw thread, Accordingly even when leak at the first connecting tube 7 and the connector of the second connecting tube 4, can also be collected by the intermediate connector 6 of sealing Water, prevent the water in pipeline from flowing out, ensure that the normal use of pipeline, the sufficient time is provided to maintenance.
The outer wrap of negative pressure connecting tube 1 has one layer of rubber sealant, by setting rubber sealant, increase negative pressure connection Sealing property between the negative pressure hole of pipe 1 and first and the second negative pressure hole, prevents leak.
The beneficial effects of the utility model are:The utility model is simple in construction, can effectively realize to the close of connecting water pipe Envelope connection, increase the sealability of junction, prevent junction because of the big explosion of pressure and the problem of leak occur, it is dual close Envelope, increase safety in utilization, and possess the function of blocking dredging.
