Abstract
The invention relates to a method for connecting pipes made from resin matrix composite material and a pipe connection structure and a method thereof. A pipe fitting and a pipe body are provided and an outside groove is arranged on the circumference of the end of the pipe body, and an inside groove is arranged on the circumference of the inner diameter of the pipe fitting. The pipe fitting is provided with an injection hole which is communicated with the inside groove, and installed on the end of the pipe body. The inside groove of the pipe fitting corresponds with the outside groove on the pipe body and filling materials are injected into the groove for solidification through the injection hole. The invention has reasonable design, simple structure, low production cost, easy installation, low labor intensity, high working efficiency and good sealing performance of pipe connection, and can save raw materials.
Description
Technical field
The present invention relates to the connecting means of the pipeline that polymer matrix composites make, structure and method that specifically a kind of pipeline connects.
Background technique
At present, the tubing that polymer matrix composites are made, its pipe joint Placement mainly contains two kinds of structural types.A kind of pipeline made from glass fibre reinforced plastics connects, and generally is to connect by internal and external threads, at two pipe joint places, sticks with glue the pipe fitting that is connected to band external pipe thread, Internal Pipe Thread respectively, will have an end of external pipe thread to have an end of Internal Pipe Thread to be connected with another.Because pipe is long, in screwing tight process, labor intensity is big, and efficient is low.Another kind of connect with link, the link made from steel is made up of a threaded joint, shouldered joint and a nut.During operation, two joints be sticked with glue respectively on body, nut sleeve with pad one rubber cushion in the middle of two joints, gets final product nut screwing clamping then in shouldered joint one side again.The connection of this dual mode all will connect with glue, and the quality of glue and the quality of gluing directly influence the join strength of pipe, in the process of operation, is difficult for the quality of connection between assurance two pipes, is prone to disconnection, causes pipeline to reveal.
Summary of the invention
The objective of the invention is provides manufacturing a kind of simple in structure, reasonable in design, easy in order to solve the deficiency of above-mentioned technology, and easy for installation, the efficient height can guarantee the join strength between pipe joint and body, structure and method that the pipeline of good seal performance connects
The present invention solves the scheme that its technical problem takes: structure and method that a kind of pipeline connects, be provided with pipe fitting, body, the circumference that it is characterized in that the body end is provided with outer groove, pipe fitting internal diameter circumference is provided with inner groovy, pipe fitting is provided with injection orifice, and injection orifice communicates with interior rectangular recess, and pipe fitting is installed on the body end, the interior rectangular recess of pipe fitting is corresponding with the outer rectangular recess on the body, enters in the rectangular recess by injection orifice injection packing and solidifies.
The method that pipeline connects is characterized in that:
A, on mould, make pipe fitting, solidify the back and extract mould out with winding process;
B, on the body end processing outside groove;
C, pipe fitting bore area, outer surface of tube body are processed, pipe fitting and body fitting surface have magnitude of interference, magnitude of interference 0.1mm;
D, pipe fitting are installed in the body end, and relative axial position makes inner groovy corresponding with outer groove;
The preparation of E, packing: press resin 100g, curing agent 1-2g, catalyzer 1-3g, the weight ratio of silica sand 20-80g is mixed, and stirs;
F, injection: packing is packed in the injecting glue device, be full of groove by the injection orifice injection.
G, curing: on pipe fitting, twine the heating tape, heated 10 minutes, 60 ℃-70 ℃ of heating-up temperatures.
The present invention is reasonable in design, and is simple in structure, and low cost of manufacture can be saved raw material, installs easily, and labor intensity is low, high working efficiency, and the sealing for tubing joints performance is good.
Description of drawings
Describe the present invention by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Mark among the figure: 1, pipe fitting, 2, injection orifice, 3, packing, 4, body, 5, groove, 6, rubber cushion.
Embodiment
By shown in Figure 1, structure and method that a kind of pipeline connects, be provided with pipe fitting 1, body 4, groove 5 outside on the circumference of body 4 ends, being provided with, pipe fitting 1 internal diameter circumference is provided with inner groovy 5, pipe fitting 1 is provided with injection orifice 2, the diameter 3mm of injection orifice, injection orifice 2 communicates with inner groovy 5, and pipe fitting is installed on the body end, the inner groovy of pipe fitting is corresponding with the outer groove on the body, enters in the groove by injection orifice 2 injection packings 3 and solidifies.In the structure that pipeline connects, be provided with one or more equidistant inside and outside grooves 5, can improve the intensity of connection part.
The method that pipeline connects, employing is on mould, make pipe fitting 1 with winding process, solidify the back and extract mould out, on body 4 ends with pipe fitting 1 joint processing outside groove 5, to pipe fitting 1 bore area, the processing of polishing of body 4 outer surfaces, pipe fitting 1 has magnitude of interference with body 4 fitting surfaces, magnitude of interference 0.1mm, to avoid packing to enter between the groove outer pipe fitting and body, earlier pipe fitting 1 is installed in body 4 ends, relative axial position makes inner groovy 5 corresponding with outer groove 5, the preparation packing, add certain curing agent with thermosetting resin, catalyzer, silica sand, press resin 100g, curing agent 1-2g, catalyzer 1-3g, the weight ratio of silica sand 20-80g is mixed, stir, make packing not only evenly but also have a good flowability, packing is packed in the injecting glue device, injection packing 3 in injection orifice 2, packing 3 is full of in the rectangular recess 5, on pipe fitting, twine the heating tape, heated 10 minutes, 60 ℃-70 ℃ of heating-up temperatures are after waiting to solidify, the rubber cushion 6 of packing into, another root pipe fitting 4 is installed in the pipe fitting 1, relative axial position makes inner groovy 5 corresponding with outer groove 5 again, and packing is packed in the injecting glue device, injection packing 3 in injection orifice 2, packing 3 is full of in the rectangular recess 5, twines the heating tape on pipe fitting, heats 10 minutes, 60 ℃-70 ℃ of heating-up temperatures can connect moulding.The present invention is reasonable in design, and is simple in structure, owing to adopt injection technique can save raw material, reduces working strength of workers, increases work efficiency; Behind the injection packing, can utilize the shear strength of packing to overcome the problem that the original intensity that forms by the adhesive property and the gluing quality of glue can't guarantee join strength between pipe joint and body, because the designability of packing and rectangular recess, the present invention can be widely used in pipeline and connect.
