Abstract
The invention relates to a novel electrofusion-jointing bell and spigot structure of a polyethylene-wound structural wall pipe. The novel electrofusion-jointing bell and spigot structure consists of a polyethylene pipe main body, an auxiliary support wall, a bell mouth and a spigot, wherein the bell mouth and the spigot are respectively arranged at two ends of the polyethylene pipe main body; and the outer wall of the polyethylene pipe main body is wound so that the auxiliary support wall is formed. The novel electrofusion-jointing bell and spigot structure is characterized in that a raised annular table is formed at one end of the outer wall of the spigot, which is close to the polyethylene pipe main body; and a circle of electric heating elements are embedded in the outside end surface of the bell mouth or the outside end surface of the raised annular table. The novel electrofusion-jointing bell and spigot structure of the polyethylene-wound structural wall pipe, which is provided by the invention, is scientific and reasonable in structural design; and the electric heating elements are arranged on the outer end surface of the bell mouth or the spigot. The novel electrofusion-jointing bell and spigot structure has the advantages of convenience in processing, low consumption of raw materials, high consistency in product processing, favorable connecting sealing property and excellent connecting reliability.
Description
Technical field
The invention belongs to the plastic tube processing technique field, the novel electric smelting of particularly a kind of polyethylene spirally enwound structure-wall tubular product connects faucet structure.
Background technique
The environmental protection polyethylene spirally enwound structure-wall tubular product is the ideal substitute of metal and concrete duct.It has light weight, corrosion-resistant, thermal conductivity is low, exhausted source performance is good, flow resistance is little, do not play dirt, anti-secondary pollution, life-span length, quick construction, characteristics such as easy to maintenance.And, connect joint socket through the set electric smelting in tubing two ends and connect, can realize purposes such as the zero seepage of pipeline, stressed, anti-uneven settlement.Pipeline is mainly used in petrochemical industry, port and pier, rainwater and the sewage collecting and the discharging of power station (nuclear power, thermoelectricity), town road.
Polyethylene spirally enwound structure-wall tubular product is hot technology entwining tube; With the high-density polyethylene resin is main raw material(s); Adopting hot winding shaping process, is auxiliary support structure with the polypropylene single-wall corrugated pipe, a kind of special construction wall pipe with higher critical external compressive resistance ability of processing.The faucet structure of existing polyethylene spirally enwound structure-wall tubular product is by the made socket of tubing one end, and a bellmouth that the other end is made and a circle electric heating element that on the bellmouth inwall, embeds constitute.After the tubing joint socket installs, adopt special-purpose electric welding machine to connect electric heating element, make its heating, the socket outer surface is connected with bellmouth internal surface thermofusible spigot.The sealing that existing faucet structure connects because of factor affecting pipelines such as the size of joint socket diameter, processing conformity easily the interface leakage problems then occurs easily for the heavy caliber polyethylene spirally enwound structure-wall tubular product, and reliability is relatively poor.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of raw materials consumption amount few, product processing conformity is high, and the novel electric smelting of the polyethylene spirally enwound structure-wall tubular product that sealing for tubing joints property is good connects faucet structure.
It is to adopt following technological scheme to realize that the present invention solves its technical problem:
The novel electric smelting of a kind of polyethylene spirally enwound structure-wall tubular product connects faucet structure; Constitute by polyvinyl piping materials main body, supplemental support wall, bellmouth, socket; Two ends in the polyvinyl piping materials main body are shaped on bellmouth, socket respectively; Twine at the outer wall of polyvinyl piping materials main body and to be shaped on the supplemental support wall, it is characterized in that: be shaped on the protruding ring platform at the socket outer wall near an end of polyvinyl piping materials main body, be embedded with a circle electric heating element at the outside end face of the outside of bellmouth end face or protruding ring platform.
Advantage of the present invention and beneficial effect are:
It is reasonable that the novel electric smelting of polyethylene spirally enwound structure-wall tubular product of the present invention connects faucet structure design science, and electric heating element is arranged on the exterior edge face of bellmouth or socket, has easy to process; The raw materials consumption amount is few; Product processing conformity is high, connects good airproof performance, the advantage that connection reliability is good.

Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
The novel electric smelting of a kind of polyethylene spirally enwound structure-wall tubular product connects faucet structure; Constitute by polyvinyl piping materials main body 1, supplemental support wall 2, bellmouth 3, socket 5; Two ends in the polyvinyl piping materials main body are shaped on bellmouth, socket respectively; Twine at the outer wall of polyvinyl piping materials main body and to be shaped on the supplemental support wall, it is characterized in that: be shaped on protruding ring platform 6 at the socket outer wall near an end of polyvinyl piping materials main body, be embedded with a circle electric heating element 4 at the outside end face of the outside of bellmouth end face or protruding ring platform.
Processing method of the present invention is:
With the high-density polyethylene resin is main raw material(s); With the polypropylene single-wall corrugated pipe is auxiliary support structure; Raw material is delivered to heating in the extruder, plasticizing, homogenizing after runner, mouthful mould are extruded into flat strip respectively and in order to coat the arc strip of skeleton pipe through the vacuum feeder; Equidistantly be wrapped on the die surface; Demoulding finishing behind the cooling and shaping is shaped on the protruding ring platform at the socket outer wall near an end of polyvinyl piping materials main body, is embedded with a circle electric heating element at the outside end face of the outside of bellmouth end face or protruding ring platform.During construction, the joint socket of adjacent tubing is connected, adopt special-purpose electric welding machine to connect electric heating element then and heat, socket is connected with bellmouth end face thermofusible spigot.After the connection, jointing intensity is higher than tubing itself, can not move or the effect of load is ruptured owing to soil, has good sealing property, and reliability is splendid.
