With greatly promoting the safety in utilization of pipeline.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the schematic cross-section of the present invention；
Fig. 3 is the assembling schematic diagram between the elastic rubber pipe and sealing ring of the present invention.
Coding in figure is respectively：1 is splicing tubes, and 2 be sealing ring, and 3 be water inlet aperture, and 4 be the aperture that meets water, and 5 be water inlet
Channel, 6 be elastic rubber pipe, and 7 be associated drain channel, and 8 be drainage channel.
Specific implementation mode
As shown in Figures 2 and 3, this spliced drainage pipeline, includes the pipeline master being made of more than one splicing tubes 1
Body, the cylinder hollow-core construction of splicing tubes 1 are respectively provided among it there are one drainage channel 8, and adjacent two splicing tubes 1 are direct
Docking setting, interface are respectively provided with a sealing ring 2, and the both sides of sealing ring 2 face splicing tubes and open up an annular cavity
(not shown), the both ends open end of splicing tubes 1, which seals, to be incorporated in annular cavity, and the centre of each sealing ring 2 is around sealing ring 2
One circle opens up more than one through-hole, and partly overlap conducting between adjacent two through hole, and a piece bullet of setting is both passed through in each through-hole
Property rubber tube 6, elastic rubber pipe 6 is inserted in through-hole, and squeezes contact between the elastic rubber pipe 6 of adjacent both ends mutually,
By the mutual adhering and sealing of gluing between contact surface, between each elastic rubber pipe 6 mutually adhering and sealing form one it is closed
Loop configuration.
In the present embodiment, the centre of elastic rubber pipe 6 is respectively provided with an associated drain channel 7, and the upstream face of sealing ring 2 is just
One aperture 4 that meets water is opened up to every elastic rubber pipe, an intake tunnel is respectively provided in the sealing ring 2 inside the aperture 4 that meets water
5, a water inlet aperture 3 is opened up on the elastic rubber pipe of 5 output end of intake tunnel, water inlet aperture 3 is led with associated drain channel 7
It is logical.Each sealing ring when in use, 8 proper drainage of drainage channel, and drain during, if pipeline inside water pressure is very big, that
, water can pass through drinking-water aperture be squeezed into the associated drain channel of each elastic rubber pipe and carry out assisted drainage, effectively be let out
Pressure, use are more safe.
Wherein, the top surface of elastic rubber pipe 6 opens up a horizontal contact face, and horizontal contact face stretches out in sealing ring 2 one
End is sealed with the inner wall gluing of splicing tubes 1, and the effect that horizontal contact face is arranged mainly increases elastic rubber pipe and splicing tubes
The bond area of inner wall increases the fastness after bonding.
In the present embodiment, sealing ring 2 is made of silica gel material, and outer diameter is more than the outer diameter of splicing tubes, sealing ring it is outer
Side dimpling is in the lateral surface of each splicing tubes.
Each splicing tubes 1 are all made of the pvc pipe of hard.Elastic rubber pipe 6 is preferably provided after being adhered to splicing inside pipe wall
In shape is stretched, so after installation is complete, each elastic rubber pipe restores elastic deformation due to needing, and can tense the splicing of both sides
Pipe so that splicing tubes can be compressed with intermediate sealing ring, reach better seal, and when being sheared, both ends can be detached
Splicing tubes, after separation, each internal elastic rubber pipe can stretch, as shown in Figure 1, will not still be broken, in drawing process
It needs to overcome shearing force, therefore using the elastic force of each elastic rubber pipe, plays the buffering to external shearing, extruding force, increase
Add the safety of whole pipeline, and elastic rubber pipe has extraordinary elastic force, be when outside is not very huge and its
Be not easy it is cut-off, after the completion of shearing, the playback of each elastic rubber pipe, sealing.
The beneficial effects of the invention are as follows：The present invention is made of the splicing of more than one splicing tubes, and inner sealing is provided with
The elastic rubber pipe of one circle, therefore when being sheared, two splicing tubes of abutting end can be detached so that internal elastic rubber
Pipe stretches, and resists shearing, has extraordinary anti-shear ability, and internal elastic rubber pipe can also make as explosion-proof buffering
With greatly promoting the safety in utilization of pipeline.
