Abstract
The utility model relates to a tube union which replaces the screw thread blocking type connection or single outer layer metal adhesive connecting used in metal and plastic complex tube. A tube body 1 of the metal and plastic complex tube includes an outer layer of metal 3 and an inner of plastic. The utility model is characterized in that: the inner plastic end on one end of the tube is provided with a drawing step 4 which extends out from the outer layer metal for a certain length and forms the union of the metal and plastic complex tube with an insolated metal blocking ring 6, which is shown in the figure. The utility model has the advantages of a neat shape, reliable connection, wide utilization and low manufacturing cost and is a new tube connecting produce; therefore, the utility model is fit for various metal and plastic complex tubes.
Description
The utility model relates to a kind of new-type permanent connected type pipe coupling that has replaced type pipe connectors such as metal is connected with the screw thread FERRULETYPE that plastic composite pipe is used always, single outer layer metal is bonding, is applicable to that mainly the metal of systems such as plumbing, air feed, chemical industry, heating power is connected with the pipeline of plastic composite pipe.
The pipeline Placement of existing metal and plastic composite pipe, generally be by screw thread FERRULETYPE or the adhered connection of single outer layer metal, this Placement pipe fitting cost height, join strength and poor reliability, construction intensity is big, efficient is low, and technology is comparatively complicated, is difficult to satisfy the needs of modernization construction.
The purpose of this utility model provides and a kind ofly replaces that the screw thread FERRULETYPE connects and the bonding metal that is connected of single outer layer metal and plastic composite pipe joint, its low cost of manufacture, connect reliably, installation is easy rapidly.
The purpose of this utility model is achieved in that metal and plastic composite pipe joint, its pipe fitting body (1) is made of outer layer metal (3) and plastic lining (2), it is characterized in that: the termination of the plastic lining of this pipe fitting one end is provided with undergauge step (4) and exceeds the outer layer metal certain-length, has constituted metal and plastic composite pipe joint (5) jointly with metal collar (6) independently.
During above-mentioned design and installation, the end that composite pipe is inserted in metal collar (6) in elder generation, insert special-purpose hot melt instrument in the termination of the termination of the inner plastic (2) of above-mentioned pipe fitting one end and composite pipe again plastics are heated, pipe is inserted pipe fitting, its plastic lining is welded together; Then, make metal collar (6) cover the interface section of pipe fitting and tubing, and make and stick with glue or the mode of soldering is combined with each other the collar inwall of metal and the outer layer metal at tubing and pipe fitting interface position, thereby form connection lasting, firm, sealing, reach replacement screw thread FERRULETYPE and connect and the bonding effect that is connected of single outer layer metal.
Below by accompanying drawing, embodiment the utility model is described further again.

As shown in Figure 1: the utility model comprises that pipe fitting body (1) is made of outer layer metal (3) and plastic lining (2), it is characterized in that: the termination of the plastic lining of this pipe fitting one end is provided with undergauge step (4) and exceeds the outer layer metal certain-length, has constituted metal and plastic composite pipe joint (5) jointly with metal collar (6) independently.
As shown in Figure 2: during the utility model connection, the outer layer metal (12) of the inwall of the outer layer metal of pipe fitting end (3) and composite pipe is bonding or skewer is welded together by metal collar (6), inner plastic (11) hot melt of inner plastic of pipe fitting end (2) and composite pipe causes pipe fitting body (1) and composite pipe (10) to form firm being connected together.
Shown in Fig. 3,4,5: wherein, the other end of pipe fitting body (1) also is the end (5) of metal and plastic composite pipe joint structure.Wherein, this pipe fitting body (1) is straight tube, 45 ° of bend pipes or 90 ° of bend pipes.
As shown in Figure 6: wherein, pipe fitting body (1) is decompression reducing type, and its small end also is the end (5) of metal and plastic composite pipe joint structure.
Shown in Fig. 7,8,9,10: wherein, the other end of this pipe fitting body (1) is outside thread (7) or internal thread (8) or flange (9).Wherein, this pipe fitting body (1) is straight tube or 90 ° of bend pipes.Certainly, also may 45 ° of bend pipes.
Shown in Figure 11,12,13,14: wherein, this pipe fitting body (1) is threeway bifurcated pipe or equal tee or reducing tee or straight cross or reducing cross.Wherein, this pipe fitting body threeway or the four-way bifurcated pipe mouth of pipe are the end (5) of internal thread (8) or outside thread (7) or flange (9) or metal and plastic composite pipe joint structure.
Therefore the utility model pipe fitting can make the outer layer metal of whole pipeline and inner plastic all connect into an integral body, the delamination of having avoided the multiple tube double layer material to cause because of expanding with heat and contract with cold.In addition, the utility model pipe shape is simple, easily processing, and the outer layer metal wall is thin, and the plastics proportion is big, saves material, and cost is low.The external diameter of this pipe fitting also approximates the external diameter of composite pipe greatly, when pipe with after it is connected, can keep roughly suitable external diameter, guaranteed that the utility model outward appearance is clean and tidy, attractive in appearance.Thus, the utility model is the composite pipe pipeline connection product of a new generation.
