Abstract
The utility model relates to a pipeline connecting device which comprises a connecting casing pipe arranged between pipelines and sealing members arranged between each of the pipelines and the connecting casing pipe, wherein at least one pipe end of the connecting casing pipe is provided with a sealing member, the end surface of one side of the sealing member is provided with a clamping slot which mutually corresponds to and matched with the pipe end of the connecting casing pipe, and the end part of the connecting casing pipe is embedded in the clamping slot, meanwhile, the inner side of the sealing member is provided with at least three sealing lips, the axial cross section of each sealing lip is in the shape of a sawtooth and the sealing lips are orderly and tightly sheathed on the outer walls of the pipelines. The utility model has the advantages of simple and reasonable structure, low fabricating cost, convenient installation and use, good sealing property and long service life.
Description
The utility model relates to a kind of connection set that is used for connecting tube.
Existing assembling pipe joint, structure mainly comprises: be arranged on the adapter sleeve between pipeline and the pipeline, and be arranged on Sealing between pipeline and the adapter sleeve, adapter sleeve is made by rigid material, Sealing is made by elastic material, offer draw-in groove on Sealing one side end face with the corresponding cooperation of adapter sleeve, the pipe end of adapter sleeve is embedded in the draw-in groove of Sealing, Sealing tightly is enclosed within the outside of pipeline, and between pipeline and adapter sleeve, form sealing, realize being tightly connected by adapter sleeve and Sealing between the pipeline.In above-mentioned assembling pipe joint, because the pipe end of adapter sleeve is directly to be embedded in the draw-in groove of Sealing, and between Sealing and pipeline, has only one deck sealing, therefore, in use, the sealing effect of Sealing is relatively poor, and Sealing is also easily from the coming off of adapter sleeve, thereby influences the working life of assembling pipe joint.
It is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, Sealing and adapter sleeve sound construction, the assembling pipe joint that sealability is reliable and stable.
For realizing the purpose of this utility model, a kind of assembling pipe joint comprises: be arranged on the adapter sleeve between the pipeline, and be arranged on Sealing between pipeline and the adapter sleeve, at least one pipe end place is provided with Sealing at described adapter sleeve, on the end face of Sealing one side, offer draw-in groove, the mutual corresponding matching of the pipe end of draw-in groove and adapter sleeve, the end of adapter sleeve is embedded in draw-in groove, simultaneously, the inboard of Sealing is provided with at least three circle sealing lips, the axial cross section indention of sealing lip closely is set on the outer wall of pipeline successively.
The utility model has the advantages that: simple and reasonable, cost is low; Easy to install; Good seal performance, and long service life.
Following structure accompanying drawing is described in further detail the utility model:
Fig. 1 is the structural representation of a kind of assembling pipe joint of the utility model;
Fig. 2 is the structural representation of another kind of assembling pipe joint of the present utility model;
Fig. 3 is the structural representation of the third assembling pipe joint of the present utility model;
Fig. 4 is the structural representation of the 4th kind of assembling pipe joint of the present utility model;
The structural representation of Fig. 5 the 5th kind of assembling pipe joint of the present utility model;
1, pipeline, 2, adapter sleeve, 3, Sealing, 4, draw-in groove, 5, sealing lip, 6, spacing back-up ring, 7, annular surface.
As shown in Figure 1, a kind of assembling pipe joint comprises: be arranged on the adapter sleeve 2 between the pipeline 1, and be arranged on Sealing 3 between pipeline 1 and the adapter sleeve 2, adapter sleeve 2 is made by rigid material, two pipe end places of adapter sleeve 2 are provided with Sealing 3, Sealing 3 is made by elastic material, on the end face of Sealing 3 one sides, offer draw-in groove 4, the mutual corresponding matching of pipe end of draw-in groove 4 and adapter sleeve 2, the end of connecting tube 2 is embedded in draw-in groove 4, and simultaneously, the inboard of Sealing 3 is provided with five circle sealing lips 5, the equal indention of the axial cross section of every circle sealing lip 5 closely is set on the outer wall of pipeline 1 successively; The center fixed of described adapter sleeve 2 is provided with the spacing back-up ring 6 of a circle, the internal diameter of spacing back-up ring 6 is consistent with the internal diameter of pipeline 1, be provided with the annular surface 7 of a circle projection at the pipe end of described adapter sleeve 2, axial cross section along annular surface 7 is circular arc, the shape of draw-in groove 4 matches with the shape of adapter sleeve 2 pipe ends, also is corresponding circular arc along its axial cross section.
Shown in Fig. 2,3,4, the annular surface 7 of adapter sleeve 2 pipe ends and draw-in groove 4 be corresponding matching respectively, and are corresponding trapezoidal, triangle and rectangular-shaped respectively along its axial cross section, also can adopt other shape.
As shown in Figure 5, its basic structure is the same, a pipe end place of adapter sleeve 2 is provided with Sealing 3, the other end of adapter sleeve 2 then is fixedly installed on than on the large pipeline 1, and in the centre of adapter sleeve 2 spacing back-up ring 6 is not set, Sealing 3 is identical with embodiment 1,2,3 and 4 with the structure shape of adapter sleeve 2 pipe ends.
In the utility model, Sealing 3 inboards preferably are provided with five circle sealing lips 5, it is better that four to six circle sealing lips 5 are set usually, but had better not be less than three-layer sealed lip 5, otherwise can influence fruit of its sealing, if but sealing lip 5 be provided with too much, then make comparatively bothering, because above-mentioned Sealing 3 inboards are provided with the above sealing lip 5 of three circles at least, so the sealing between sealing part 3 and the pipeline 1 is more reliable; In addition, in the utility model, owing to be provided with the annular surface 7 of a circle projection in the end of adapter sleeve 2, corresponding with it Sealing 3 draw-in grooves 4 are mated the phase embedding, therefore, adapter sleeve 2 combines more tight with Sealing 3, be difficult for during use obscission takes place, and sealability is also more reliable.
