Abstract
A large-diameter plastic wound pipe with a socket comprises a large-diameter straight-pipe section which is formed by spirally winding a plastic square pipe and by welding through hot-melt adhesive, and a socket section which is formed by winding one end of the straight-pipe section through plastic tapes. The large-diameter plastic wound pipe with a socket in the utility model is formed in one piece, saves labor, saves electric energy, and has the advantages of increased connection strength between pipe fitting and pipe workpiece, convenience for field installation.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of large diameter plastic winding tube with joint socket.
Background technique
At present, the tubing that domestic underground water supply and drainage pipe-line system is used mainly contains concrete pipe, concrete reinforced pipe and cast iron tube, because it is bigger than length and vehicle flowrate that it builds the time limit, the buried concrete waste pipe in some highway section and cast iron water pipe are damaged in succession aging, cause municipal drainage to stop up, the water pipe explosion, not only bring inconvenience to citizen's life, and because of working procedure complicated, the pipe joint number is more, leakage proof is difficult in time handling, accumulate over a long period and not only can cause road foundation to sink, effluent seepage, also can pollute soil property, the water source becomes public hazards.For this reason, adopt have good withstand voltage, light weight, corrosion-resistant, environment protection type tubing become the task of top priority.
Recent years, all types of plastic tubing rises gradually at home, and progressively replaces concrete pipe, concrete reinforced pipe and cast iron tube.With respect to concrete pipe, concrete reinforced pipe and cast iron tube, plastic tube have light weight, corrosion-resistant, the low pollution or free of contamination remarkable advantage, and plastic tube is also longer working life under identical withstand voltage condition.What plastic tube was relatively more commonly used at present is the pvc pipe material, though price is lower, it is heavier to exist quality, and withstand voltage deficiency has shortcomings such as a small amount of pollution.And the HDPE solid wall pipe, though function admirable, cost is higher, waste material.So a kind of novel plastic winding structural wall tube arises at the historic moment, it has kept the advantage of common plastics tubing, has overcome their some shortcomings simultaneously again.
The polythene winding structure wall pipeline purposes is boundless, and its main advantage can use mini-plant to produce the tubing of bore greater than 2000mm aspect bore.But because the raw material that polythene winding structure wall pipeline uses mainly is a polyethylene, though and polyethylene self has toughness preferably, but Young's modulus is less, the tubing of making is if satisfy the ring stiffness of tubing, must increase the product substance, even like this, in a lot of practical engineering application, because limitation of field condition, often make outer pipe wall be easy to be subjected to scratch or impact and produce broken hole, thereby influence the product engineering application quality, can't satisfy the requirement of mal-condition, so the application and the development of polythene winding structure wall pipeline have been limited.
In the prior art, high-density polyethylene double-wall winding plastic drain-pipe socket fitting (DN1600 is following) often adopts the method for mold injection to make; Big caliber pipe fitting (DN1600 and more than) is not finished local plastic as yet because of the too big integral molded plastic of injection moulding regional extent and has been cooled off to flow and cause and can't be shaped, so big caliber pipe fitting often adopts steel to mould socket joint link in compound (or stainless steel) elastic packing, relatively inconvenience is installed.
The model utility content
The purpose of this utility model provides a kind of large diameter plastic winding tube with band joint socket of new structure for the problems referred to above that overcome the prior art existence exactly.
The purpose of this utility model is achieved in that a kind of large diameter plastic winding tube with joint socket, comprises by plastics square tube spiral twining and the major diameter straight length that is made of welded connection with hot melt adhesive and directly twine the joint socket section that forms at straight length one end by plastic tape.
The nominal diameter of described major diameter straight length is equal to or greater than 1200mm, described joint socket section flare.
The large diameter plastic winding tube of the utility model band joint socket compared with prior art has the following advantages and effect:
1, only needs time processing promptly plastic, the saving of labor, save time, and do not have the disadvantage of secondary oxidation degraded.
2, the employing of joint socket section is Wrapping formed, and the plastics heating-up temperature requires low than injection moulding, and manufacture cost is saved in power saving.
Description of drawings
Fig. 1 is the perspective view of the large diameter plastic winding tube of the utility model band joint socket;
Fig. 2 is the sectional structure schematic representation of the straight length in the utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the large diameter plastic winding tube of band joint socket of the present utility model comprises by plastics square tube 11 spirals and twining and major diameter straight length 1 that is made of welded connection with hot melt adhesive 12 and the joint socket section 2 that is directly formed in the winding of straight length one end by plastic tape.The nominal diameter of major diameter straight length wherein is equal to or greater than 1200mm, joint socket section flare.
The making method of the large diameter plastic winding tube of band joint socket of the present utility model is, at first make pellet according to the prescription of plastic raw material, again pellet is dropped into large-scale screw extruder, produce plastic square pipe racks material, then the square tube band is sent into wind and carried out the spiral winding and be welded to connect into double-wall winding plastic tubing, again double-wall winding plastic tubing fixed length cutting is become straight length with hot melt adhesive.Then straight length is fixed on the Stetch Wrapping Machine and at joint socket internal mold of one end socket.Adopt in addition with the pellet of making plastic square pipe racks material same recipe and produce plastic strap by extrusion shaping machine, plastic strap drawn while hot send into Stetch Wrapping Machine, on straight length and joint socket internal mold, twine the joint socket section that pressing formation and straight length fuse under the heat tracing state, promptly becoming the large diameter plastic winding tube of band joint socket after the demoulding.
Straight length in the utility model and joint socket section adopt with a kind of plastic raw material of prescription and make.The matrix of this plastic raw material preferably adopts high density polyethylene (HDPE).
Claims (2)
1, a kind of large diameter plastic winding tube with joint socket is characterized in that: comprise by plastics square tube spiral and twining and the major diameter straight length that is made of welded connection with hot melt adhesive and directly twine the joint socket section that forms at straight length one end by plastic tape.
2, the large diameter plastic winding tube of band joint socket as claimed in claim 1 is characterized in that: the nominal diameter of described major diameter straight length is equal to or greater than 1200mm, described joint socket section flare.
