Description
Technical field
The present invention relates to pipe joint field, be specifically related to a kind of entwining tube spigot-and-socket joint.
Background technology
Polyethylene plastic-steel winding pipe (SRWPE) is to be welded (on faying surface through spiral winding by the heterotypic strip of steel plastic compount
Extrusion welding) to make, its inner wall smooth is smooth, and specification is DN200-DN3000mm.This kind of tubing have corrosion-resistant, light weight,
The advantages such as simple installation, through-current capacity are big, life-span length (50 years), alternative high energy consumption material (cement, cast iron, pottery etc.) makes
Tubing, belongs to environment-friendly product.
It was connected with each other the various pipe joints of employing between polyethylene plastic-steel winding pipe to be attached in the past, but many connect
Head is not the most starved and can be well connected and sealed, and after connecting, the short time will occur joint leakage phenomenon, and some seal effect
But the best joint cost is the highest, it is impossible to well promoted the use of.
Such as Chinese Patent Application No. 201220003239.0, disclose a kind of pipe connected for polyethylene plastic-steel winding pipe
Joint, it includes spiral pipe body, is separately fixed at the plug-in unit sleeve pipe outside spiral pipe body two ends and holds
Cannulated, insert
Part sleeve pipe is made up of the first serpentine pipe and the first straight tube, have inside the first serpentine pipe match with evagination spiral and
Rotation direction is identical
Spiral grooves, and between the first serpentine pipe and the first straight tube, be provided with the first flange projection, the first serpentine pipe rotation
Merge fixing
One end at spiral pipe body；Socket joint sleeve pipe is made up of the second serpentine pipe and the second straight tube, outside the first straight tube
Footpath less than or
Internal diameter equal to the second straight tube.Although above-mentioned patent by spiral pipe body two ends port and socket joint sleeve pipe and
Plug-in unit poverty pipe
Junction is respectively adopted sweat soldering connected mode, improves the sealing of product, but its first serpentine pipe and
Second spiral
Be respectively equipped with the spiral grooves coordinated with plastic-steel spirally-wound pipe on pipe, by this spiral grooves make the first serpentine pipe and
Second spiral
Pipe screws with spiral pipe body respectively and is connected, and therefore this pipe joint is only applicable to twine with the plastic-steel of identical screw thread
Around pipe, knot
Structure is complicated, and processing cost is high.
And for example Chinese Patent Application No. 201220614450.6, disclose a kind of self-locking connected for plastic-steel spirally-wound pipe
Pipe joint, including plug-in unit sleeve pipe and socket joint sleeve pipe, plug-in unit sleeve pipe includes the first corrugated tubing and the first straight tube, socket joint set
Pipe includes
Two corrugated tubings and the second straight tube；The first described corrugated tubing and the second corrugated tubing are provided with and plastic-steel spirally-wound pipe external screw thread
Three coordinated
Head 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
One straight tube
Port is provided with one group of buckle coordinated with the second straight tube, solves the problem that existing pipe joint intensity is bad, but
It is this kind of pipe
Joint difficulty of processing is big, and die manufacturing cost is high, and weight is big, and especially this pipe joint once pins and occurs leaking
Or other hair
Time sick, joint cannot unload, and only destroys a joint and just can solve problem, directly results in the increase of cost.
