Description
Technical field
The present invention relates to entwining tube docking field, be specifically related to a kind of method that entwining tube connects.
Background technique
Polyethylene plastic-steel winding pipe (SRWPE) welds (welding extruded by faying surface) by the heterotypic strip of steel plastic compount through spiral winding to make, and its inner wall smooth is smooth, and specification is DN200-DN3000mm.This kind of tubing has corrosion-resistant, quality light, simple installation, through-current capacity are large, the life-span is long advantages such as (50 years), the tubing that alternative high energy consumption material (cement, cast iron, pottery etc.) makes, genus environment-friendly product.
Be interconnected between polyethylene plastic-steel winding pipe in the past and adopt various pipe joint to connect, but many jointings are not starved and can be well connected and sealed, after connecting, joint leakage phenomenon will be there is in the short time, but the joint cost of some good sealing effects is too high, can not well be promoted the use of.
As Chinese Patent Application No. 201220003239.0, disclose a kind of pipe joint connected for polyethylene plastic-steel winding pipe, it comprises spiral pipe body, be separately fixed at the plug-in unit sleeve pipe outside spiral pipe body two ends and socket joint sleeve pipe, plug-in unit sleeve pipe is made up of the first volute and the first straight tube, have inside first volute and to match with evagination spiral and the identical spiral grooves of rotation direction, and between the first volute and the first straight tube, being provided with the first flange projection, the first volute screws and is fixed on one end of spiral pipe body; Socket joint sleeve pipe is made up of the second volute and the second straight tube, and the external diameter of the first straight tube is less than or equal to the internal diameter of the second straight tube.Although above-mentioned patent is by adopting sweat soldering Placement respectively at spiral pipe body two ends port and socket joint sleeve pipe and conjunction place of plug-in unit poverty duct ligation, improve the sealing of product, but its first volute and the second volute are respectively equipped with the spiral grooves coordinated with plastic-steel spirally-wound pipe, by this spiral grooves, the first volute and the second volute are screwed respectively to be connected with spiral pipe body, therefore this pipe joint is only applicable to the plastic-steel spirally-wound pipe with identical screw thread, complex structure, processing cost is high.
And for example Chinese Patent Application No. 201220614450.6, disclose a kind of self-locking type pipe joint connected for plastic-steel spirally-wound pipe, comprise plug-in unit sleeve pipe and socket joint sleeve pipe, plug-in unit sleeve pipe comprises the first threaded pipe and the first straight tube, and socket joint sleeve pipe comprises the second threaded pipe and the second straight tube; The first described threaded pipe and the second threaded pipe are provided with the triple thread coordinated with plastic-steel spirally-wound pipe outside thread; The port of the first straight tube is provided with one group of buckle coordinated with the second straight tube.Although above-mentioned patent is provided with one group of buckle coordinated with the second straight tube in the port of the first straight tube, solve the problem that existing pipe joint intensity is bad, but this kind of pipe joint difficulty of processing is large, die manufacturing cost is high, weight is large, and especially this pipe joint occurs leaking or other defect once pinning, and joint cannot unload, only have destruction joint just can deal with problems, directly cause the increase of cost.
Summary of the invention

2) two sections of plastic tubes are divided into left pipe and right pipe, one end car of left inner tube wall has annular groove, the corresponding annular groove internal diameter of the other end inwall carries out turning inwall, turning stops when annular groove position, retain an annular boss, then drive a circular trough in the other end end and have annular slot in the middle of circular trough, or the other end end Inner rises an annular rounded groove; Right Guan Ze carries out turning at the inwall internal diameter of the corresponding left pipe of the other end outer exterior wall, and turning is to outer diameter and inner diameter location of equal, and the turning length of outer wall is equal with inwall turning length;
3) left pipe and right pipe and entwining tube are connected and sealed, and first use PE polyethylene resin or stabilizer to carry out injecting glue sealing to plastic tube and joint, entwining tube outer end, then carry out injecting glue sealing to the top of entwining tube and the joint of plastic pipe inner wall; Or open three elongated slots to the outer wall of plastic tube, elongated slot leads in annular groove, carries out injecting glue, till filling like this by elongated slot in annular groove;
4) dock be tightly connected left pipe and right pipe of entwining tube, put into seal ring in the circular trough that first left pipe turning goes out or annular rounded groove, right pipe inserts in left pipe again, and connection completes.
For the 4th) described seal ring in step comprises circle body, pawl, annular fixture block and collar stop, circle body is cylindric, pawl is designed with respectively in the middle of inside circle body and near end position, the neutral position, outside of circle body is designed with annular fixture block, collar stop is designed with outside the other end of circle body, whole seal ring is loaded in circular trough, and in annular fixture block embedded rings shape draw-in groove, collar stop is stuck in the end of circular notch.
For the 4th) described seal ring in step comprises circle body and pawl, and being semicircle shape outside circle body, is cylindric inside circle body, and be designed with pawl respectively near end positions inside circle body, the circular cylinder shaped portion of circle body is just in time installed in annular rounded groove.
Described left pipe and right pipe except can shaping by turning except, can also die sinking injection moulding integrated molding be passed through.
Advantage of the present invention is that method is simple, easy to operate, effective connection entwining tube is also by injecting glue mode of the present invention, effective sealing, No leakage, can not get loose, the cooperation processing method of left pipe and right pipe makes them mutually dock, and can effectively be sealed by the effect of seal ring, the pawl design of seal ring can prevent pipeline expansion from getting loose, and can well seal.
