Abstract
The utility model discloses an ultra-high molecular weight polyethylene pipe electric smelting and socket welding device and belongs to the technical field of ultra-high molecular weight polyethylene pipe connecting and machining. The ultra-high molecular weight polyethylene pipe electric smelting and socket welding device comprises a first pipe and a second pipe and is characterized in that a flaring is arranged on a connection part of the first pipe, an insertion opening is formed in a connection part of the second pipe and is conical, and an electric heater strip is embedded in the upper half portion of the insertion opening. The ultra-high molecular weight polyethylene pipe electric smelting and socket welding device has the advantages that due to the fact that the insertion opening is conical, the insertion opening and the heater strip can be inserted into the flaring conveniently; due to the cooperation between an inner core supporting piece and a pressurizing device, the flaring and the insertion opening can be connected more closely, and the welding sealing performance is good.
Description
Technical field
The utility model relates to a kind of ultrahigh molecular weight polyethylene tubing and connects processing technique field, especially relates to ultrahigh molecular weight polyethylene tubing electric smelting socket weld device.
Background technique
At present, ultrahigh molecular weight polyethylene tubing Placement is mainly that flange connects, and flange connection exists interface not tight, the problem of joint leakiness material; The hot melt of tubing connects, adopt again pipeline opposite and heating plate to touch the dock welding manner of fusing degree, also there is the mode that uses Electric thermal smelting belt at pipe material inner wall, the former cannot ensure the intensity of pipe joint, the latter is because Electric thermal smelting belt has certain thickness, causes that institute's connecting tube latus rectum diminishes, cumbersome, the supporting installation cost of use instrument is high.
Model utility content
The utility model provides a kind of welding quality good, the ultrahigh molecular weight polyethylene tubing electric smelting socket weld device that welding junction intensity is high, pressure-bearing is large.
The concrete technological scheme adopting of the utility model is:
Ultrahigh molecular weight polyethylene tubing electric smelting socket weld device, comprises that the first tubing, the second tubing is characterized in that, the first tubing joint is provided with enlarging, and the second tubing joint is provided with socket, and described socket is taper, and first is embedded with electrical heating wire socket.Described enlarging is to form after first tubing one end adds thermal expansion; Can allow socket easily enter in enlarging; Socket is that taper can facilitate socket to insert in enlarging, and electrical heating wire partly buries and facilitates electrical heating wire to enter in enlarging.
Preferably, be provided with inner core supporting element on the inwall of described socket, the outer installment of described enlarging has pressurization device.Inner core supporting element and pressurization device coordinate that enlarging is connected with socket is tightr.
Preferably, when pressurization, in the axial direction of the first tubing, the second tubing, pressurizing tool is set, footpath pressurization device upwards, wherein, pressurization device comprises semicircular top board, press table, top board, press table two ends are provided with fixing ear, and top board, press table connect by the clamping bolt being arranged on fixing ear; In the time of pressurization, firmly evenly, increase gradually pressure.
Compared with prior art, the utility model has the advantages that:
1) socket is that taper can facilitate socket and electrical heating wire to insert in enlarging;
2) inner core supporting element and pressurization device coordinate that enlarging is connected with socket is tightr, weld seam good airproof performance.
Brief description of the drawings
Structural representation when Fig. 1 is the utility model welding;
Fig. 2 is the utility model welding pre-structure schematic diagram;
Cross-sectional schematic when Fig. 3 is the utility model welding;
In figure, 1, the first tubing, 2, the second tubing, 3, enlarging, 4, socket, 5, electrical heating wire, 6, inner core supporting element, 7, pressurization device.
Embodiment
As shown in Figure 1, 2, 3, ultrahigh molecular weight polyethylene tubing electric smelting socket weld device, comprises the first tubing 1, the second tubing 2, the first tubing 1 joint is provided with enlarging 3, the second tubing 2 joints are provided with socket 4, and described socket 4 is taper, and first is embedded with electrical heating wire 5 socket 4; On the inwall of socket 4, be provided with inner core supporting element 6, the outer installment of described enlarging 3 has pressurization device 7.
Working process of the present utility model is:
(1) the first tubing of preparation electric fusion welding, the port of the second tubing are put together, horizontal positioned holds up, the end hacking of the socket on the second tubing, make the conical surface, and electrical heating wire is partly embedded in socket, and heating wire is drawn, prop up with inner core at this section of internal diameter;
(2) the heating of the end of one end of the first tubing, it is expanded, make enlarging;
(3) use external force, make socket insert enlarging, then, electrical heating wire energising heating, make the temperature of tubing melting zone progressively rise to 200 degree by 130 degree; In heating process, in the outside of enlarging along circumference and axially progressively pressurization.This heating, pressure process is according to the difference of caliber and wall thickness, is controlled at 30-45 minute, the pipe slurry that makes tubing melting zone along holding, socket interface evenly oozes out, and carries out heat-insulation pressure keeping;
(4) heat, pressurize and be complete, after cooling 10 minutes, remove compression appliance, remove the inner core of socket, electric fusion welding is complete, and joint is carried out.
Claims (2)
