Abstract

The utility model discloses an electric melting and hot melting double-protection connecting structure of polyolefin plastic pipes, which comprises a left polyolefin plastic pipe and a right polyolefin plastic pipe in opposite butt joint by means of hot melting. Hot melting connecting spots are formed on the hot melting butt-joint surfaces of the two polyolefin plastic pipes, an electric melting sleeve is sleeved outside the butt-joint position of the two polyolefin plastic pipes, an electric heating wire is arranged on the inner wall of the electric melting sleeve, and the inner wall of the electric melting sleeve is fused and fixedly connected with the outer pipe walls of the two polyolefin plastic pipes after electric hot melting welding. The electric melting and hot melting double-protection connecting structure can function in double protection to connection of the polyolefin plastic pipes and improve stability of the connection.

Description

The two protection of the electric smelting hot melt of polyolefin plastics tubing linkage structure
Technical field
The utility model relates to a kind of pipe connecting structure, specifically is meant a kind of two protection of electric smelting hot melt linkage structure of polyolefin plastics tubing.
Background technique
Plastic tube is the capital equipment that progressively becomes conveying in recent years, comprising plastic tube and steel skeleton plastic clad pipe material etc.It is applied to various fields such as municipal administration, oil, chemical industry, building, shipbuilding, communication, electric power and underground gas pipeline.As middle pressure pipe road, seabed channelling, electricity (light) cable conduit, Net cage for breeding fish at seabed rack etc. is the tubing of new generation that substitutes traditional pipe fitting at present, is described as environmental protection tubing.The connection of current polyolefin plastics tubing mainly contains electric smelting, and butt joint is connected dual mode with hot melt in succession.
The principle that the hot melt butt joint connects is that two welding end surface are heated to uniform temperature, applies enough power then with their butt welding together.This power makes smelt fully mix, thereby welds together.This kind method is subject to the influence of environment personal factor, causes the melting degree inequality, is easy to generate gap generation leakage phenomenon thereby make two pipes connect the interface.
It is to be wrapped in electrically-heated-wire on the metal mandrel of mould earlier or to be wrapped in that prefabricated polyethylene is thin to put that electric smelting connects, and puts into injection mould and is injection molded into the electric melting pipe fittings of imbedding electrically-heated-wire.In the construction work, energising makes the electrothermal wire heating, thereby pipe fitting and two pipes are bonded together.This method shortcoming is that electrothermal wire heating's inequality can cause pipe fitting or tubing melting degree difference, and fusion is crossed conference and caused bubble to produce the gap, and the too small meeting of fusion causes connecting defective tightness.
Be that hot melt connects or the electric smelting connection all can cause the joint to produce gap generation leakage phenomenon, when the line transportation poisonous and harmful substance, this leakage will bring great potential safety hazard, especially the polyolefin steel skeleton plastic clad pipe is applied in the submarine pipeline engineering, because the ad hoc environment and the special process of marine pipe laying, two relatively weak pipe joints go wrong easily, and the seabed maintenance difficult, in case occur leaking or breaking expending very huge.
The model utility content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and the two protection of the electric smelting hot melt linkage structures of the high polyolefin plastics tubing of a kind of plastic tube connection safety and reliability are provided.
For achieving the above object; the technical solution of the utility model is a kind of two protection of electric smelting hot melt linkage structure of polyolefin plastics tubing; two polyolefin plastics tubing of relative hot melt butt joint about including; form the hot melt tie point on the hot melt interface of these two polyolefin plastics tubing; the joint overcoat electric heating of described two polyolefin plastics tubing melts sleeve; the molten sleeve lining of this electric heating is provided with electric heating wire; after the electric heating fusion welding; the outer tube wall of the molten sleeve lining of electric heating and two polyolefin plastics tubing fuses together, and is fixedly connected.This be provided with utilize method that hot melt butt joint connects with the port of tubing with electric hot plate heating back butt-fusion, guarantee to stablize its preliminary connection, the molten sleeve of electric heating that will set in advance electric heating wire again be placed on two pipes tentatively heat melt joint, energising makes it produce heat and coupling sleeve inwall and tubing outer side wall is fused into one, the so just further tubing joint intensity that improves guarantees that the sealing of tubing joint reduces the probability that leakage occurs.
Further being provided with is that described plastic tube is a steel skeleton plastic clad pipe.
Advantage of the present utility model is: the utility model plays the effect to the two protections in polyolefin plastics tubing joint; there is hot melt to connect preliminary its connection sealing that guarantees on the one hand between the tubing; electric melting pipe fittings inwall and two pipe joint outer walls merge one on the other hand, further guarantee the tubing connection stability.Solve single connecting means and produced leakage and the not enough problem of join strength.Make it reach the ocean environment usage requirement, reduce the probability that breaks down, reduce maintenance cost.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

Embodiment
Embodiment of the present utility model as shown in Figure 1, two polyolefin plastics tubing 1 of relative hot melt butt joint about including, form hot melt tie point 3 on the hot melt interface of these two polyolefin plastics tubing 1, the joint of described two polyolefin plastics tubing 1 is arranged with the molten sleeve 4 of electric heating outward, be provided with electric heating wire 2 in the molten sleeve 4 of this electric heating, and the outer tube wall of molten sleeve 4 inwalls of this electric heating and two polyolefin plastics tubing 1 fuses together, and is fixedly connected.The utility model utilize method that hot melt butt joint connects with the port of tubing 1 with electric hot plate heating back butt-fusion, guarantee to stablize its preliminary connection, the molten sleeve pipe 4 of electric heating that will set in advance electric heating wire 2 again be placed on two pipes tentatively heat melt joint, energising makes it produce heat and molten sleeve 4 of electric heating and polyolefin plastics tubing 1 outer side wall is fused into one, the so just further polyolefin plastics tubing 1 joint intensity that improves guarantees that the sealing of polyolefin plastics tubing 1 joint reduces the probability that leakage occurs.In addition, the described polyolefin plastics tubing 1 of present embodiment is Steel Skeleton polyolefine plastic composite pipe 1.
