Abstract
The utility model discloses an electric fritting tube sealing device comprising a sealing ring (2) and a hollow electric fritting tube (1) made in thermoplastic material provided with spiral-distributed electric heating device (7) such as electric resistance on the inner wall and two electric connectors to connect the electric heating device and the external power on both ends. The middle portion of the cavity of the electric fritting tube (1) is provided with a positioning structure (4) protruding to the inner portion of the tube. A concavo-convex groove is arranged on the connection portion of the positioning structure and the sealing ring to fix the sealing ring (5) matching the concavo-convex groove. The utility model has the advantages that the utility model is simple in structure; confinement of the tubes is reliable and infiltration can be prevented no matter the fritting process forms welding holes on the outer wall of the tubes or not and exposure of the web frame does not decrease the effect which greatly increase the practicability of fritting connection, remove potential safety hazard and ensure the safety to use.
Description
Technical field
The utility model relates to a kind of pipe fitting that makes and connects electrothermal smelting tube seal arrangement more closely.
Technical background
Along with the leap progress of high polymer material technology, the development and use of plastic tube also deepen constantly.Various plastics such as polyethylene (PE) tubing, polypropylene pipe are extensive use of the also corresponding continuous development of the interconnective various technology of pipeline enclosure in industry and civilian multiple field.Consider steel-plastic composite pipe and the steel wire wrapped tubes used from safety and durable angle at present, characteristic of pipe material is outer and internal layer is two-sided composite thermoplastic plastics more, and the centre is a reinforced layer.Reinforced layer is metal wire structure layer or the high-tensile steel wires winding layer that can strengthen the compressive strength of tubing.When pipeline connected, composite pipe was because of its many electricity consumptions of characteristics hot melt interconnection technique.Electric heating fusion welding technology is by electric heating, the new technology that swagelok and straight tube overcoat are fused into one.But in reflow process, electric heating device may make outer pipe wall and reinforced layer burn-through, if water penetrates into the tubing reinforced layer, pipe fitting is damaged, and causes liquid in pipe or gas leakage, and is accidents caused possibly, forms potential safety hazard.
Summary of the invention
The utility model provides a kind of electrothermal smelting tube seal arrangement, and the not good problem of sealability when solving present electrothermal smelting tube and connecting the thermoplastic pipe improves the practicability of electric heating fusion welding technology, replaces the not high Butt sealing place structure of existing reliability.
The technical solution of the utility model is: a kind of electrothermal smelting tube seal arrangement, comprise electrothermal smelting tube and seal ring, electrothermal smelting tube is the hollow component of being made by thermoplastic material, inwall is provided with the electric heating devices such as electric heating wire of spiral distribution, and two ends are provided with the electric connecting joint that is communicated with electric heating device and external power.Electrothermal smelting tube cavity middle part is provided with the position structure to the pipe internal projection, and position structure and seal ring joint are provided with tongue and groove, is used for fixing the seal ring that tongue and groove therewith mates, and makes that seal ring is unlikely to be deviate from use.Employing has higher elasticity and plastic rubber, the seal ring that materials such as plastics are made is stepped shaft, the wall thickness of seal ring is greater than the wall thickness of the tubing of need connection, during pressurization, seal ring can be blocked pipe fitting inner wall and outer pipe wall because of the inhomogeneous slit that may exist of welding, even outer pipe wall is portalled by weldering in welding process, or spill also impact effect not of web frame, material can not enter the slit between pipe fitting and the tubing in the seal action of seal ring made and manages, therefore material can not be spilt by the slit in the pipe, or penetrate into the reinforced layer of composite plastic pipe by aperture, damage tubing.
When carrying out the pipeline connection, the concavo-convex position of seal ring is embedded in the position structure one side tongue and groove, chucking can not move up and down it, after inserting the tubing that needs to connect, be communicated with electric connecting joint and external power, the heating of electric heating device entire body makes pipe fitting inner wall and tube wall be fused to one, finishes the connection of pipeline.The pipe fitting that is used to connect many tubing needs with every tubing joint position structure is being set, and installs seal ring.
The utility model has the advantages that simple in structure, no matter and whether reflow process can make outer pipe wall form welding hole, or spill also impact effect not of web frame, all can realize the sealing of pipeline effectively, prevent seepage, thereby improved the molten practicability that connects of electric heating greatly, eliminated safe hidden trouble, ensured safe in utilization.

Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1, a kind of electrothermal smelting tube seal arrangement comprises electrothermal smelting tube 1 and seal ring 5.Electrothermal smelting tube 1 is the hollow component of being made by thermoplastic material, and inwall is provided with the electric heating devices such as electric heating wire 7 of spiral distribution, and two ends are provided with the electric connecting joint 6 that is communicated with electric heating device 7 and external power.Electrothermal smelting tube 1 cavity middle part is provided with the position structure 4 to the pipe internal projection, and position structure and seal ring 5 joints are provided with tongue and groove, is used for fixing the seal ring 5 that concaveconvex shape therewith mates, and makes that seal ring is unlikely to be deviate from use.The outer wall 12 and the thickness between the inwall 13 of tubing 2 are tube wall thickness, seal ring 2 wall thickness are greater than tubing 2 wall thickness, seal ring just can be blocked pipe fitting 1 inwall and tubing 2 outer walls because of the inhomogeneous slit that may exist 8 of welding like this, even tubing 2 is portalled by weldering in welding process, material can not enter the slit 8 between pipe fitting and the tubing in the seal action of seal ring 5 made and manages, therefore material can not be spilt by the slit in the pipe, or penetrates into the reinforced layer 3 of composite plastic pipe by aperture, damages tubing.
As Fig. 2, the seal ring 5 that employing has materials making such as higher elasticity and plastic rubber, plastics is stepped shaft, the concavo-convex position 11 of seal ring can accurately embed in the side tongue and groove of position structure 4, and the wall thickness of seal ring is the thickness between seal ring outer wall 9 and the seal ring inwall 10.
The forms that to be two bodys among the embodiment connect by pipe fitting, the utility model can be made of the electrothermal smelting tube and the supporting with it seal ring of multiple class such as elbow, threeway, flange and many specifications.The position structure of electrothermal smelting tube middle part projection has multiple shape, and the seal ring that matches is as the same.Can just not belong to scope of the present utility model with the position structure shape with the different of present embodiment because of seal ring.
