The invention adopts the external welding type electric melting connection, the pipes are simple, convenient and light in the aspect of installation and connection, the connecting seal performance is good, and the strength of the pipe at the connecting position is high.
Description
Technical field
The invention belongs to the pipeline connection area, particularly relate to the interconnection technique in the ducted heavy caliber pipe of municipal engineering.
Technical background
The ducted heavy caliber pipe Placement of municipal engineering mostly is Placements such as Hough is solidly connected, hot melt is extruded and is welded to connect, heat-shrinkable tube (band) connection, the connection of electric smelting band outward at present.These Placements are difficult control in actual application, and are higher to installation requirement, assembler's duration.
China Patent No. is the pipes consisting of thermoplastic plastics that 87202443 utility model patent discloses a kind of embedded resistance wire, is characterized in being embedded with resistance wire at the interface inwall of injection molding pipes consisting of thermoplastic plastics.When the resistance wire heating power, outer pipe wall and the fusion of resistance wire contact segment are bonded together itself and pipe fitting securely.Because this model utility is embedded in the interface inwall of pipe fitting with resistance wire, make that the tubing that will connect can only be enclosed within the pipe fitting in the middle of actual the use, only be suitable for minor caliber pipe, for heavy caliber pipe, particularly the connection between the tubing of super large caliber such as municipal pipeline then obviously can't be used.
Chinese patent application number is the self-pressing electrothermal fusion method for joining that 02114008.1 patent of invention discloses a kind of plastic tube, this method is that the plastics connecting sleeve is carried out reaming and be connected tubing assembling, the connecting sleeve that utilization is swollen produces thermal shrinkage, make the cover with pipe between the aspect that is connected be subjected to uniform pressure, then to connecting the electric heating wire heating power of aspect, the plastically welding that makes the connection aspect together, thereby realized that fusion connects under pressure---self-pressing electrothermal fusion method for joining.The related technological scheme of this application for a patent for invention also is that connection tubing is enclosed within the plastics connecting sleeve, can't be applied to the connection area of heavy caliber pipe equally, and connection procedure also needs the plastics connecting sleeve is carried out enlarging, and the electric heating wire scene need be around in the connection pipe outer surface, make complex procedures, be subjected to job site and workmen's the influence of operative skill bigger, be difficult to form the effective standard of delegation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of pipes connecting method that reduces installation difficulty, after connecting, make connection fittings combine together, thereby the pipeline of the sealing effect of realizing ideal connects with being connected tubing.
In order to realize the foregoing invention purpose, the technological scheme of employing is as follows:
A kind of connecting means of tubing, it links together two tubing by link, realizes as follows:
(1), the two ends of link is inserted into the connecting end of tubing respectively;
(2), the thermal conductor that will be arranged on the link connects electric smelting equipment, make the thermal conductor heating produce heat and reach the melt temperature of tubing and link, and then make link under molten state, combine with tubing;
(3), the cooling, link and tubing are combined together.
The present invention produces heat by the thermal conductor heating and reaches the melt temperature of pipe material, and then link is combined under molten state again with tubing, and cooling rear connectors and tubing combine together.Link can adopt the tubing identical with pipe material to be connected, as entwining tube or solid wall pipe etc.
In the technique scheme, described step (1) also better is connected with two tubing by the spacing link that makes of installation is set on link.Install and spacingly when install connecting, play positioning action, make that the surface of contact between two tubing to be connected and the link is comparatively impartial, make that also the joint that connects back tubing is more firm.
Further, installing spacing is the projection that is arranged at link outer surface intermediate portion.Guaranteed that like this link is inserted into the two ends area equalization that connects tubing, made fusion connect the stressed also impartial of latter two tubing, helped connecting the steadiness of tubing.
The part of the thermal conductor of step of the present invention (2) heating fusion is the link outer surface that is in contact with one another and the internal surface of tubing connecting end.
The setting of the thermal conductor of described step (2) is by twining heating wire or heating silk screen or assembling heating tape realization on the outer surface of the two ends of connecting body on the outer surface of the two ends of connecting body.As another kind of scheme, described thermal conductor can also be arranged at the connecting end inside of connector main body, makes thermal conductor not expose, and is not only attractive in appearance but also can not cause thermal conductor to come off.
Described step (2) is by being provided with the terminal that are connected with thermal conductor at link, described terminal may extend to the link outside to connect electric smelting equipment.By terminal are set, terminal are connected with thermal conductor on the one hand, extend to outside the connector main body on the other hand, so during use, only need connect the heating that electric smelting equipment then can be realized thermal conductor at terminal.
(3) of the present invention be cooled to air-cooled or natural cooling.
Realize connecting means of the present invention, link can adopt plastic tube or pipe fitting.
When connector main body adopts plastic tube, can adopt winding structure wall pipe or solid wall pipe material as the plastic tube of connector main body.Winding structure wall pipe is suitable for the connection between the entwining tube, and it makes the joint that connects back tubing except firm, and toughness is also higher.And heavy caliber pipe is the entwining tube structure usually, be as the connector main body between the heavy caliber pipe, and its bore certainly will be also bigger, so adopt winding structure wall pipe proper; The solid wall pipe material then can be selected for use according to actual needs, is more suitable for usually in the connector main body as the minor caliber pipe connection, but the heavy caliber solid wall pipe is also arranged in the reality, and it also can be used as the connector main body that heavy caliber pipe connects.
Pipe fitting as link can adopt straight-through or threeway or four-way or elbow.So it is spacing at pipe fittings such as straight-through, threeway, four-way or elbows thermal conductor, terminal and installation to be set, and can satisfy the demand of most of pipeline connection area.
As approximate scheme, realize that thermal conductor required for the present invention also can be provided with the internal surface with connecting body, the connection of tubing is by being inserted into two tubing connecting ends to be connected in the connecting body at this moment, connecting hot melt equipment, make the thermal conductor heating, be connected with the internal surface fusion of connecting body so that connect the outer surface of tubing.
The present invention adopts outer fusing type electric smelting linkage structure, and is easier to be light and handy aspect the installation connection, and connects good seal performance, tubing joint intensity height.
The present invention is in implementation process, behind the job site, only need connector main body is installed into tubing, electric smelting equipment connects heating conductor by tenminal block, make heating conductor produce the melt temperature that heat reaches pipe material, and then make connector main body under molten state, combine again with tubing, cooling rear connectors main body and tubing combine together, just finish tubing and connect.
