Abstract
The utility model discloses a novel pipeline telescopic joint with the advantages that the novel pipeline telescopic joint is formed through integral forming, the sealing effect is good, and the installation is convenient. The novel pipeline telescopic joint comprises an outer pipe, an annular hoop and a sealing ring, wherein the annular hoop is arranged at one end of the outer pipe, the middle of the inner wall of the outer pipe is provided with an annular position limiting lug boss, the outer pipe and the annular hoop are formed through being integrally connected, an annular groove is arranged on the inner wall of the annular hoop, and the sealing ring is arranged in the annular groove.
Description
Technical field
The utility model relates to a kind of structural material, more particularly relates to a kind of novel pipeline slip joint.
Background technique
Slip joint is mainly used in the piping erection industry, says having many uses of slip joint from the angle of specialty, and effect is the compensation extraction duct dilatation that is heated and causes, absorbs and reduces the influence of vibration equipment to pipeline, absorbs earthquake, the earth subsidence amount of deformation to pipeline.The slip joint kind has: bellow-type expansion joint, sleeve slip joint, tube-inserted type slip joint etc.Tube-inserted type slip joint is wherein often used in drainage pipeline; Such as at the toilet drainage pipe if passing through floors; Just must every layer slip joint be set all, make the joint of joint and arm of waste pipe not loose, split, and the position of assurance passing through floors be water-tight.Waste pipe on the exterior wall also must be used the slip joint pipe fitting.In addition, the water horizontal drain pipe reaches certain-length also must be provided with the slip joint pipe fitting, is used for the connection between the tube and tube.
At present; Common tube-inserted type slip joint; Mainly by cylindrical outer tube, be located at the circumferential band of cylindrical outer tube one end and the rubber seal be located in the circumferential band is formed, because circumferential band fixes through glue with cylindrical outer tube and be connected, after use a period of time; Come unstuck easily, ftracture between circumferential band and the outer tube, the fluid in causing managing spills.In addition, circumferential band and cylindrical outer tube are the split settings, during production, need offer die production respectively, and cost of production is than higher, and when using, also want earlier circumferential band and cylindrical outer tube are coupled together through glue fixing, and operation is more, installs also cumbersome.
Summary of the invention
Therefore, to the problem of above-mentioned existence, the utility model supplies a kind of one-body molded, good sealing effect, novel pipeline slip joint easy for installation.
For solving this technical problem; The utility model is taked following scheme: a kind of novel pipeline slip joint, comprise outer tube, circumferential band and seal ring, and said circumferential band is located at an end of outer tube; The outer tube wall middle part is provided with a ring-type positive stop lug boss; Said outer tube links to each other with the circumferential band one and forms, and the circumferential band inwall is provided with circular groove, and seal ring is located in the circular groove.
Further, said seal ring inwall indention structure, and constitute by 1～3 road tooth.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model links to each other with outer tube circumferential band and processes through a mould one, not only save the cost of mold developing, reduces production costs; And when installing and using; Only need other pipelines directly be inserted in the outer tube, it is easier to construct, and has also alleviated working strength of workers simultaneously; In addition, because seal ring inwall indention structure when other pipelines are plugged in the outer tube, can be anchored on pipeline in the outer tube better,, can not cause tube and tube to produce yet and come off even the fluid impact in the pipeline is big again.Because circumferential band and outer tube are one to link to each other and processes the problem appearance that can not come unstuck, ftracture because of having, and good sealing effect.
Description of drawings
Fig. 1 is the partial cutaway diagrammatic sketch of the utility model;
Fig. 2 is the structural representation of the utility model outer tube and circumferential band.
Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 1, Fig. 2; The utility model embodiment discloses a kind of novel pipeline slip joint; Comprise outer tube 1, circumferential band 2 and seal ring 3, said outer tube 1 is one cylindric, adopts the TPU material to process; Said circumferential band 2 is located at an end of outer tube 1, and outer tube 1 inwall middle part is provided with a ring-type positive stop lug boss (not shown).Said outer tube 1 links to each other with circumferential band 2 one and forms, and during production, only needs mould of exploitation, has saved cost of production; Circumferential band 2 inwalls are provided with circular groove 21, and seal ring 3 is located in the circular groove 21, and said seal ring 3 adopts rubber to process; Its inwall indention structure; And constitute by 2 road teeth, in the time of in other pipelines insert outer tube 1, can better other pipelines be anchored in the outer tube 1; Even the fluid impact in the pipeline is big again, can cause tube and tube to produce yet and come off.
When the utility model is installed, only need other pipelines directly be inserted in the outer tube 1 of the utility model, just can play the effect of connecting tube; Saved the operation of spreading glue, sheathed circumferential band, it is easier to construct, and seal ring 3 inwalls adopt the design of zigzag structure; Can better other pipelines be anchored in the outer tube 1; Even the fluid impact in the pipeline is big again, can not cause tube and tube to produce yet and come off, sealing effect is better.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
Claims (2)
1. novel pipeline slip joint; Comprise outer tube, circumferential band and seal ring; Said circumferential band is located at an end of outer tube, and the outer tube wall middle part is provided with a ring-type positive stop lug boss, and it is characterized in that: said outer tube links to each other with the circumferential band one and forms; The circumferential band inwall is provided with circular groove, and seal ring is located in the circular groove.
2. novel pipeline slip joint according to claim 1 is characterized in that: said seal ring inwall indention structure, and constitute by 1～3 road tooth.
