Abstract
The utility model relates to a polyvinyl saddle-type pipe, belonging to connecting device of branch pipeline. The utility model comprises a saddle type main body, an end cap, a bore cutter which is arranged inside the saddle type main body and a bumper pin. An electric heating plate with electric heating wires is connected with the connecting terminals which are positioned at the two sides of the electric heating plate in advance to form a saddle main body through pressure injection. The bore cutter with an O-shaped sealing ring forms a double sealing structure with the O-shaped sealing ring which is positioned on the external wall of a through hole at the screw thread end of the saddle type main body. The pipe is sleeved with the end cap. The welding adopts a fully automatic microcomputer control. The saddle pipe can take a three-way type or a through type. The connection of the pipe has the advantages of simple structure, easy operation and no danger. The utility model is widely used in systems such as natural gas, coal gas, petroleum pipe and water pipe with little influence from human activity.
Description
Technical field
The utility model belongs to the coupling arrangement of tap line, particularly is applicable to the coupling arrangement of plastic tube.
Background technology
In the past gas ductwork construction, under the situation of operation of ventilating, the embedding three-way pipe is spliced with new discharge pipe on existing pipeline and the new discharge pipe.Owing to be band gas operation, the requirement on free again relates to user's air feed again, and through step-down construction commonly used, the mode of blocking source of the gas adopts sleeve method or the flange method of splicing of splicing, and connects new pipeline.Specifically with reference to Shanghai science tech publishing house, Xi Decui chief editor " pipeline network of fuel gas in city design and construction " concrete chapters and sections.In these structures,, be subjected to man's activity bigger, and easily cause poisoning, burning and explosive incident because material and structure limitation implement operating difficulties.
Summary of the invention
Branch line pipe fitting fast hitch mechanism is to be embedded into electronic type polyethylene saddle type pipe fitting, a saddle type pipe fitting is installed on tubing 8, it is by saddle type main body 5, saddle type collet 10, end cap 1, be loaded on the bore cutter 4 in the saddle type main body, backing pin 15 is formed, saddle type main body 5 and saddle type collet 1 have four corresponding through holes, use four bolts 12 respectively, packing ring 13, nut 11 is fastened on the saddle type pipe fitting on the tubing 8, the electric hot tray 9 that heating wire is housed is pre-installed in the binding post 7 of both sides, through pressure injection-moulded one-tenth saddle type main body 5, there is the screw thread port outside, upper end of saddle type main body, end cap 1 has internal thread and saddle type main body upper end thread connection, bore cutter 4 is equipped with in the inside of saddle type main body, annular groove is arranged at bore cutter top, interior dress O RunddichtringO 3, saddle type main body upper end sidewall also has annular groove, interior dress O RunddichtringO 2, in the bore cutter top circular groove backing pin 15 is housed, on the saddle type lower body part shoulder peep hole 14 is arranged.The saddle type pipe fitting can be triplet type or through-type.Having adopted this is raw-material fast hitch mechanism with polyethylene, reduced cost, make the pipe fitting corrosion resistance and good, life-span is long, need not step-down construction and has realized band gas operation on the complete meaning, has no danger, exempted artificial influence factor, easy to operate, can satisfy the demand of gas ductwork, and be widely used in systems such as natural gas, coal gas, petroleum pipeline and waterpipe.

The specific embodiment
The utility model is embedded into electronic type polyethylene saddle type pipe fitting and comprises saddle type main body 5, forms with as a whole two binding posts 7 of saddle type main body 5 injection mouldings and the electric hot tray 9 that has a heating wire.Wherein electric hot tray 9 and binding post 7 link to each other by heating wire.Saddle type main body 5 also has screw thread port inside that bore cutter 4 is housed, and is contained in the interior O RunddichtringO 3 of upper grooves, forms double sealing structures with the O RunddichtringO 2 that is loaded on saddle type main body 5 end of thread sidewalls.In the bore cutter 4 top circular grooves backing pin 15 is housed, prevents bore cutter 4 landings.Saddle type main body 5 screw thread ports one end top is rotary with polyethylene nut 1.Saddle type main body 5 and saddle type collet 10 are sleeved on the polyvinyl piping materials 8, on saddle type main body 5 and the saddle type collet 10 four corresponding through holes are arranged, pass four supporting bolts 12, packing ring 13, nut 11 respectively, saddle type pipe fitting is fastened on the tubing 8.Its medial saddle type main body outer surface has a peep hole 14 near a terminated line terminal one end.
Electronic type polyethylene saddle type pipe fitting described in the utility model realizes that the catenation principle of new and old pipeline is, insert external power source by two binding posts 7, again by with electric hot tray 9 that binding post 7 is connected in the heating wire heating, make saddle type main body 5 and and the outer surface of tubing, near near the thawing of being heated of the polyethylene the heating wire, along with the increase of time, pipe fitting is connected the surface with tubing polyethylene is melting state, and polyethylene has by solid phase and is converted into the viscosity flow phase.Reach setting-up time, powered-down, cooling makes the polyethylene of thawing change glassy state into naturally, reaches high-quality weld bond.After welding is finished, straight tube port 6 ends on the saddle type main body 5 are connected new discharge pipe with other pipe fittings, carry out afterwards local bulge test qualified after, open the nut 1 on the saddle type pipe fitting, extract backing pin 15, driving bore cutter 4 with special boring bar tool holes on polyvinyl piping materials 8, make the ventilation of new comb road, after drilling through bore cutter 4 is put on, set up backing pin 15, prevent that bore cutter from gliding, be contained in O RunddichtringO 3 and the interior O RunddichtringO 2 of saddle type main body 5 screw threads one end port in bore cutter 4 grooves, form double-sealing device, realize good sealing effectiveness.
Welding adopts full-automatic microcomputer control cabinet to finish, and has reduced the influence of external environment, has eliminated human factor, thereby has guaranteed welding quality.
In the welding process, material in the peep hole 14 on the saddle type main body 5 can be under the effect of thermal source jack-up slowly, after welding finished, peep hole 14 surperficial materials overflowed, but the convenient construction personnel observe poly melting process with eyes, the right judgement welding quality.
In through-type polyethylene saddle type pipe fitting, only need in saddle type main body upper end with special-purpose cutter hub punching, then in the above with other pipe fitting connection.
