Abstract
The utility model discloses a connecting pipe fitting for a pipeline. The connecting pipe fitting mainly consists of a joint and a lining piece, wherein both the inner wall of the joint and the outer wall of the lining piece are provided with gibs; and the lining piece is slantingly arranged and is provided with a vent hole. The pipeline is matched with the joint and the lining piece after being heated and softened, the pipe wall of the pipeline is deformed into the gib profile modeling under the softening state, and after being cooled, the pipeline can be fused with the joint and the lining piece; due to the arrangement of the gibs, the pipeline can be more firmly connected with the joint and the lining piece. The connecting pipe fitting can be used in various occasions including elbow connection, straight connection, T-junction connection, cross connection, connection of a big head and a small head and the like.
Description
Technical field
The utility model is a kind of pipeline connecting pipe fitting, particularly relates to composite material conduit interconnection technique fields such as PPR, PE.
Background technique
Connection pipe fitting is connecting many-sided field extensive uses such as water supply, heat supply, heat supply air feed, and aspect the interconnection technique of pipe, all the time rest on: the end tapping or the fluting of pipe fitting, attack corresponding silk in the end of another pipe fitting again or open corresponding groove, by the silk and the groove interlock mutually of two pipe fittings; Finish the connection of pipe fitting, so just have a lot of deficiencys, connect back intensity such as pipe fitting and reduce, complex manufacturing is installed inconvenience, and cost is high relatively.
The model utility content
In order to overcome the problems referred to above, the utility model designs a kind of pipeline connecting pipe fitting at above-mentioned defective, mainly is made of joint and inner piece.Described inner nosepiece wall rear end and inner piece outer wall are equipped with the hook groove, and the gradient and exhaust port of inner piece design.When matching with end hook groove place and inner piece behind the joint after the pipeline thermoplastic, make the tube wall hot melt of pipeline under softening state, be deformed into the profiling of hook groove, and the joint front end still adopts the conventional hot melt mode that it is merged mutually with pipeline, pipeline and joint and inner piece will combine together after cooling, and significantly reduced the joint pipeline and dissolved the back surplus material, thereby the phenomenon that realizes reducing line clogging and increase resistance to water-flow.Also design gradient on the described inner piece and the little rear end of front end is big, the benefit of this design is: ratio is easier in the time of in pipeline enters joint, but backward more for a short time more make it to connect tightr, and inner piece also plays the correcting pipeline, thereby avoids pipeline crooked and cause pipe leakage to influence the quality of pipeline and attractive in appearance and increase resistance to water-flow when hot melt.Because the characteristics that be provided with that hook groove and gradient make that pipeline and joint are easier to the inner piece three to be connected, are connected firmly, good airproof performance, the water ability of seeing through reduce.Also be provided with exhaust port on the described inner piece, the benefit that is provided with exhaust port is: when pipeline entered joint, the air in the joint can be discharged along with entering in exhaust port of pipeline; If do not establish exhaust port when pipeline enters joint, there is air can produce resistance even bubble in the joint and caused to the pipeline quality of connection and arrive very much influence.The utility model can be used for various different occasions, comprise elbow connect, directly, threeway connection, four-way connection, CONCENTRIC REDUCER connection etc.
Benefit of the present utility model is: simple in structure, convenient to use, be easy to produce in batches, cheap etc.
Description of drawings
A kind of pipeline connecting pipe fitting structural representation of Fig. 1;
Among the figure: 1-inner piece, 2-joint, 3-pipeline, 4-hook groove, 5-exhaust port.
Embodiment
At present, plastic pipe such as PE, PVC, ABS, PPR pipe etc. have obtained using widely because of its good plasticity, convenient construction and cost advantage.When connecting between plastic pipe, the workmen needs a kind of good airproof performance, and is easy to operate, the connection pipe fitting that can connect fast.
The utility model is a kind of pipeline connecting pipe fitting as shown in Figure 1, mainly is made of joint and inner piece.Described inner nosepiece wall rear end and inner piece outer wall are equipped with the hook groove, and the gradient and exhaust port of inner piece design.When matching with end hook groove place and inner piece behind the joint after the pipeline thermoplastic, make the tube wall hot melt of pipeline under softening state, be deformed into the profiling of hook groove, and the joint front end still adopts the conventional hot melt mode that it is merged mutually with pipeline, pipeline and joint and inner piece will combine together after cooling, and significantly reduced the joint pipeline and dissolved the back surplus material, thereby the phenomenon that realizes reducing line clogging and increase resistance to water-flow.Also design gradient on the described inner piece and the little rear end of front end is big, the benefit of this design is: ratio is easier in the time of in pipeline enters joint, but backward more for a short time more make it to connect tightr, and inner piece also plays the correcting pipeline, thereby avoids pipeline crooked and cause pipe leakage to influence the quality of pipeline and attractive in appearance and increase resistance to water-flow when hot melt.Because the characteristics that be provided with that hook groove and gradient make that pipeline and joint are easier to the inner piece three to be connected, are connected firmly, good airproof performance, the water ability of seeing through reduce.Also be provided with exhaust port on the described inner piece, the benefit that is provided with exhaust port is: when pipeline entered joint, the air in the joint can be discharged along with entering in exhaust port of pipeline; If do not establish exhaust port when pipeline enters joint, there is air can produce resistance even bubble in the joint and caused to the pipeline quality of connection and arrive very much influence.The utility model can be used for various different occasions, comprise elbow connect, directly, threeway connection, four-way connection, CONCENTRIC REDUCER connection etc.
