Abstract
The utility model relates to a special joint for enhancing a compound pipeline. The special joint comprises an enhancement layer made from steel material and an inner layer, wherein the inner periphery of the inner layer is uniformly embedded with a plurality of electric heating filaments; the enhancement layer is fixedly arranged on the outer periphery of the inner layer; the inner periphery at one end of the inner layer is provided with a front edge and the outer periphery is provided with a flange; and the flange is provided with a mounting hole. During installation, only by inserting one end of the pipeline at the front edge in the joint, the pipe and the joint are electrified, heated, hot molten and connected as one. Therefore, the installation is convenient, the connection is firm and loosening is not apt to happen. In addition, the special joint is high in bearing strength (generally working pressure)40Mpa) and is simple in structure.
Description
Technical field
The utility model relates to a kind of joint, and particularly a kind of special joint of multiple tube belongs to the technical field of pipe joint.
Background technique
Strengthening multiple tube, be called for short RTP, is a kind of high-pressure plastic multiple tube, is made up of interior pipe, enhancement layer, outer tube and joint.This pipeline serviceability temperature is-42 ℃～85 ℃; The working pressure maximum can reach 16MPa, is widely used in the field of the long distance conveyings of industry such as petrochemical industry.Because it is bigger that it bears pressure, in order to ensure the Security of pipeline, to having relatively high expectations of its joint.Strengthen composite tube joint at present and have two kinds: the one, directly adopt the molten sleeve pipe of electric heating to connect, enter enhancement layer but this method can not prevent the medium or the main body of being carried, and bearing strength is less relatively, generally is no more than 4.0MPa; The 2nd: adopt the joint of metal sleeve gripping mechanism, the defective of this joint is must joint directly be processed in factory to hold the connection of only suitable minor caliber pipe (pipe continuously) at tubing.
In order to solve the problems of the technologies described above, recently, Chinese patent literature discloses a kind of special joint that strengthens multiple tube, the document patent No. is " 2008101480176 ", patent name is " strengthening the multiple tube special joint ", this joint comprises the enhancement layer that plastic internal layer of hot molten characteristic and thermoplastic and glass fibre are formed, described internal layer one end is provided with joint socket, described joint socket wall is circumferentially with the spiral ring electrical heating wire, the special joint of this structure, load performance is better, but installs cumbersomely, and sealability is relatively poor.
The model utility content
Technical problem to be solved in the utility model provides a kind of bearing strength height, enhancing multiple tube special joint easy for installation and simple in structure.
In order to solve the problems of the technologies described above, a kind of special joint that strengthens multiple tube of the utility model, comprise enhancement layer, internal layer that steel is made, evenly be embedded with some electrical heating wires on the described internal layer inner peripheral surface, described enhancement layer is fixedly installed on the outer circumferential face of described internal layer; Described internal layer one end inner peripheral surface is provided with seam, and outer circumferential face is provided with flange, and described flange is provided with mounting hole.
Above-mentioned a kind of special joint that strengthens multiple tube, wherein, the end face of described flange is provided with rubber coating.
The utility model can be realized following beneficial effect:
1, because this joint comprises enhancement layer, internal layer, the electrical heating wire that steel is made, internal layer is the polythene material pipe fitting processed, and described internal layer one end inner peripheral surface is provided with seam, and outer circumferential face is provided with flange, described flange is provided with mounting hole, during installation,, energising heating then, will manage and joint heat is melted and linked into an integrated entity as long as pipeline one end is inserted in the joint to stop portion, therefore, easy for installation, and be connected firmly, be not easy to become flexible; In addition, the utility model bearing strength height (working pressure usually〉40MPa), and simple in structure.
2, because the end face of described flange is provided with rubber coating, joint and being connected more of tubing are sealed, and make between joint and the tubing flexible, not only can avoid because tubing directly contacts with internal layer, and make the internal layer wearing and tearing, reduce the sealing that tubing connects, but also can play certain buffer function, thereby, improved the working life of joint, and improved the Security of pipeline.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of special joint that strengthens multiple tube of the utility model, comprise enhancement layer 1, internal layer 2, electrical heating wire 4 that steel is made, described electrical heating wire 4 is embedded on described internal layer 2 inner peripheral surfaces, and described enhancement layer 1 is fixedly installed on the outer circumferential face of described internal layer 2; Electrical heating wire 4 is a strip, and described internal layer 2 is the polythene material pipe fitting processed, and described internal layer 2 one end inner peripheral surfaces are provided with seam 21, and outer circumferential face is provided with flange 22, and described flange 22 is provided with mounting hole 23, and mounting hole links into an integrated entity by fastening piece and tubing.During installation,, energising heating then, will manage and joint heat is melted and linked into an integrated entity as long as pipeline one end is inserted in the joint to seam 21 places, therefore easy for installation, and be connected firmly, be not easy to become flexible; In addition, the utility model bearing strength height (working pressure usually〉40MPa), and simple in structure.In order to improve the sealing of joint, can be by on the end face of described flange 22, smearing the special binder of one deck, put into vulcanization die at last in the close coating of large end face sulfuration one deck rubber, form rubber coating 3, because the end face of described flange 22 is provided with rubber coating 3, joint and being connected more of tubing are sealed, and make between joint and the tubing flexible, not only can avoid because tubing directly contacts with internal layer, and make the internal layer wearing and tearing, reduce the sealing that tubing connects, but also can play certain buffer function, thereby, improved the working life of joint, and improved the Security of pipeline.
Add man-hour, weld the enhancement layer 1 of steel structure earlier with iron plate (pipe), packing into then, general injection PE material forms internal layer 2 in the injection mould, and on the inner peripheral surface of internal layer, bury electrical heating wire 4 underground, smear the special binder of one deck at the joint large end face again, put into vulcanization die at last at large end face sulfuration one deck rubber coating 3, and make the size of D consistent with tube outer diameter, the size of d is consistent with pipe internal diameter, in advance with tubing one end end face planing and clean and insert in the joint to stop portion, energising heating then, insulation, cooling get final product during connection.
In sum, the utility model compared with prior art has constructing operation conveniently, and the bearing strength height (working pressure〉40MPa), characteristics such as long service life.
Here description of the present utility model and application are illustrative; be not to want in the above-described embodiments with scope restriction of the present utility model; therefore, the utility model is not subjected to the restriction of present embodiment, and the technological scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
