Abstract
The utility model relates to a plastic hot-melt socket joint pipe member used for connecting composite aluminum-plastic pipes. The utility model is characterized in that the inner surface of one end of a plastic socket joint pipe member (2) is connected with the outer wall of a composite aluminum-plastic pipe (1), and the threads (4) of a metal insert (3) on the other end of the socket joint pipe member (2) is connected with the threads which is matched with a plastic or a metal member (5). The utility model has the advantages of light weight, no leakage, corrosion resistance, sanitation, low cost and long service life. The utility model can be widely used for transporting water, natural gas and other fluid.
Description
One, technical field
The utility model relates to a kind of plastic hot melt socket pipe member that the aluminium-plastic composite pipe pipeline connects that is used for, and belongs to the shaping operation field of plastic article.
Two, background technique
Along with science and technology development, people are more and more higher to the requirement of living water pipe, and aluminium-plastic composite pipe is used widely in the building water supply field.The brass pipe fitting is adopted in the connection of aluminium-plastic composite pipe, during connection it is inserted in behind the pipe fitting radially pressurization and pins.Because the intrinsic stress relaxation phenomenon of plastics is not to closely cooperate by screw thread between aluminium-plastic composite pipe and brass pipe fitting, makes aluminium-plastic composite pipe exist comparatively serious leakage problem in application, has influenced normal use in addition.Simultaneously, produce the raw material costliness of brass pipe fitting, the manufacturing process complexity, selling at exorbitant prices has also limited the further popularization of aluminium-plastic composite pipe.
Three, summary of the invention
The purpose of this utility model is that a kind of plastic hot melt socket pipe member that the aluminium-plastic composite pipe pipeline connects that is used for is provided at the deficiencies in the prior art.Adopt the thermofusible spigot instrument when this type of pipe fitting is connected with aluminium-plastic composite pipe, make also socket joint of the aluminium-plastic composite pipe outer wall that is in connection part and the fusing of socket pipe member internal surface, two parts cool off immediately and become a tight integral body.This thermofusible spigot pipe fitting has enough intensity, and the reliability height has thoroughly been stopped leakage phenomenon.
The purpose of this utility model is realized by following technical measures.
A kind of plastic hot melt socket pipe member that is used for the connection of aluminium-plastic composite pipe pipeline, the internal surface that is characterized in these socket pipe member (2) one ends is connected with the outer wall of aluminium-plastic composite pipe (1), the screw thread (4) of socket pipe member (2) the other end metal insert (3) and being threaded that plastics or metalwork (5) are complementary.
Plastics or metalwork (5) are gauge outfit, water nozzle or valve.
Socket pipe member (5) and the plastic pipe that is shaped as elbow (6), straight-through (7), threeway (8), four-way or band metal insert being connected of aluminium-plastic composite pipe (1), the material of metal insert is brass or stainless steel.
The plastics of aluminium-plastic composite pipe and socket pipe member are polyethylene or polypropylene.
The utlity model has following advantage:
1, the aluminium-plastic composite pipe outer wall is similar plastics with the socket pipe member main body, and is follow-up crosslinked no matter whether aluminium-plastic composite pipe outer wall plastics carry out, and can both fuse into one behind the thermofusible spigot, thoroughly eradicated leakage problem;
2, socket pipe member is corrosion-resistant, health, and long service life can be born big interior pressure, and safety in utilization is good, can satisfy the conveying requirement of water and rock gas and other fluid fully;
3, socket pipe member main material light weight, inexpensive, the manufacturing process maturation, final product price is cheap.Apply in China, remarkable economic efficiency and social benefit are arranged.

Five, embodiment
Several embodiments that are used for the plastic hot melt socket pipe member of aluminium-plastic composite pipe pipeline connection are provided with reference to the accompanying drawings, can not be interpreted as restriction the utility model protection domain.
The utility model is simple in structure, as shown in Figure 1, 2.Plastic hot melt socket pipe member 2 one ends and the aluminium-plastic composite pipe 1 that are used for the connection of aluminium-plastic composite pipe pipeline achieve a fixed connection the aluminium-plastic composite pipe outer wall and the socket pipe member internal surface fusing socket joint that are in connection part by thermofusible spigot instrument (commercially available), and the screw thread 4 of socket pipe member the other end metal insert 3 removably connects with the screw thread that plastics or metalwork 5 are complementary.The aluminium-plastic composite pipe outer layer plastic is polyethylene or polypropylene, and the thermofusible spigot pipe fitting is the elbow 6 that adopts plastic-aluminum combined outer tube layer same plastic to make, straight-through 7, threeway 8 or four-way, shown in Fig. 3～5, also can be the plastic pipe that has metal insert.
