Abstract
A transition joint for connecting a PVC pipeline and an HDPE pipeline comprises a transition joint body. An axial reinforcing ring is arranged in the middle of the transition joint body. The transition joint body is divided into a PVC pipeline connecting end and an HDPE pipeline connecting end through the axial reinforcing ring. The PVC pipeline connecting end is connected with the PVC pipeline and the HDPE pipeline connecting end is connected with the HDPE pipeline. A sealing ring is arranged on the outer wall of the position, close to the tip, of the PVC pipeline connecting end. A stainless steel lantern ring is arranged on the inner wall of the PVC pipeline connecting end. An annular groove is formed between the sealing ring and the axial reinforcing ring. According to the transition joint, the outer surface of the PVC pipeline connecting end is provided with the sealing ring and the annular groove. The stainless steel lantern ring is arranged in the PVC pipeline connecting end in a lining mode so that the connection tightness can be effectively improved and a gap generated by contraction of the PVC pipeline can be avoided; an axial reinforcing rib and an annular reinforcing rib are arranged in the middle of the transition joint so that when backfilling of cement is conducted, axial contraction of the pipelines and annular twisting rotation of the pipelines can be prevented; the HDPE pipeline connecting end of the transition joint is directly connected with the HDPE pipeline in a hot melting mode, so that connection is convenient, stability is good, and the transition joint is suitable for connecting the PVC pipeline and the HDPE pipeline.
Description
Technical field
The utility model belongs to pipe connecting part technical field, be specifically related to a kind of simple in structure, connect fast and good stability for connecting the transit joint of pvc pipe road and HDPE pipeline.
Background technique
Construction drainage field at home, PVC is still main flow, but along with people's growth in the living standard, there has been to higher requirement the aspects such as Security of pipeline, as HDPE construction drainage pipe-line system.And the building of most Homofloor drainage systems is not installed horizontal arm now, the right of the autonomous selection providing to owner; This just to owner select HDPE pipe-line system provide may, but the quick connection in HDPE and pvc pipe road consistent be an industry difficult problem.Because HDPE pipeline is mainly hot melt, connect, pvc pipe road mainly connects with glue; And the shrinkage of HDPE pipeline is greater than pvc pipe road, and at present also not for connecting the relevant report of the parts of pvc pipe road and HDPE pipeline.
Model utility content
For the above-mentioned problems in the prior art, the purpose of this utility model be to provide a kind of simple in structure, connect fast and good stability for connecting the transit joint of pvc pipe road and HDPE pipeline.
Described is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, comprise transit joint body, described transit joint body middle part arranges axial stiffening ring, transit joint body is divided into pvc pipe road connecting end and HDPE pipeline connecting end two-part by axial stiffening ring, it is characterized in that, on described connecting end proximal head position, pvc pipe road outer wall, seal ring is set, between seal ring and axial stiffening ring, one group of circular groove is set, pvc pipe road connecting end inwall arranges the stainless steel collar.
Described is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, it is characterized in that on described axial stiffening ring, interval arranges one group of perpendicular hoop stiffening ring.
Described is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, it is characterized in that the length of described hoop stiffening ring is 8-10mm, and width is 2-4mm.
Described is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, it is characterized in that described axial stiffening ring width is 3-5mm.
Described is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, it is characterized in that described seal ring and connecting end termination, pvc pipe road distance are 2-4mm.
Above-mentioned is a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, comprise transit joint body, transit joint body middle part arranges axial stiffening ring, transit joint body is divided into pvc pipe road connecting end and HDPE pipeline connecting end two-part by axial stiffening ring, two-part are connected with HDPE pipeline with pvc pipe road respectively, on the outer wall of connecting end proximal head position, pvc pipe road, seal ring is set, between seal ring and axial stiffening ring, one group of circular groove is set, pvc pipe road connecting end inwall arranges the stainless steel collar.The utility model one end outer surface arranges seal ring and circular groove, this section of inner liner stainless steel collar, can effectively improve connection tightness, avoid pipeline to shrink and produce gap, axial and modal circumferential stiffening rib are set at middle part, can play and prevent that pipeline axial from shrinking and pipeline distortion ring rotation after backfill cement, the other end is directly connected with HDPE pipe hot melting, easy to connect, good stability, be suitable for being connected of pvc pipe road and HDPE pipeline.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is use stateful connection schematic diagram of the present utility model.
In figure: 1-transit joint body, 2-PVC pipeline connecting end, 201-circular groove, 202-seal ring, the 203-stainless steel collar, the axial stiffening ring of 3-, 4-hoop stiffening ring, 5-HDPE pipeline connecting end, 6-PVC pipeline, 7-cement layer, 8-HDPE pipeline.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described:
As shown in Figure 1-2, a kind of for connecting the transit joint of pvc pipe road and HDPE pipeline, comprise transit joint body 1, described transit joint body 1 middle part arranges axial stiffening ring 3 and hoop stiffening ring 4, wherein hoop stiffening ring 4 is connected with axially stiffening ring 3 is vertical, the length of hoop stiffening ring 4 is 8-10mm, width is 2-4mm, axially stiffening ring 3 width are 3-5mm, transit joint body 1 of the present utility model is divided into pvc pipe road connecting end 2 and HDPE pipeline connecting end 5 two-part by axial stiffening ring 3, pvc pipe road connecting end 2 and 6 socket connections of pvc pipe road, HDPE pipeline connecting end 5 is connected with HDPE pipeline 8 hot melts, described pvc pipe road connecting end 2 proximal head positions and termination arrange seal ring 202 on the outer wall at 2-4mm place, between seal ring 202 and axial stiffening ring 3, one group of circular groove 201 is set, on circular groove 201, glue is set, for being connected of this transit joint and pvc pipe road, pvc pipe road connecting end 2 inwalls arrange the stainless steel collar 203, prevent that pvc pipe road from shrinking generation gap, affect sealing.
