Abstract
The inwall and outwall of the aluminium-plastic composite tube are connected to the interior joint and the exterior joint of the socket pipe. The main body of the socket pipe is the plastic piece, which is tightened by the metal cover with the shape matched and the metal wire loop. The socket pipe has the shape of the direct connection, the elbow pipe, the T-piece and the cross joint. The pipefitting possesses the features of light, no leaking, high temperature resistant, sanitation, low cost and long service life. Thus, it can be utilized to transport cold and hot water, natural gas and other liquid.
Description
One, technical field
The present invention relates to a kind of steel that is used for the connection of aluminium-plastic composite pipe pipeline and mould the composite hot melt socket pipe member, belong to plastics and metal composite shaping operation field.
Two, background technique
Along with science and technology development, people are more and more higher to the requirement of building pipe.Aluminium-plastic composite pipe has obtained increasingly extensive application in fields such as feedwater, heating and gas transmissions.FERRULETYPE copper pipe fitting is adopted in the connection of aluminium-plastic composite pipe, during connection it is inserted in behind the pipe fitting joint body with the pinning of radially pressurizeing of cutting ferrule and nut.Because the intrinsic stress relaxation phenomenon of plastics is not to closely cooperate by screw thread between aluminium-plastic composite pipe and copper pipe fitting, makes aluminium-plastic composite pipe have comparatively serious leakage problem in application, has influenced normal use in addition.Simultaneously, the raw material costliness of production of copper pipe fitting, manufacturing process is numerous and diverse, and selling at exorbitant prices has also limited the popularization of aluminium-plastic composite pipe.
Three, summary of the invention
The objective of the invention is provides a kind of steel that is used for the connection of aluminium-plastic composite pipe pipeline to mould the composite hot melt socket pipe member at the deficiencies in the prior art.This type of main pipe body is a working of plastics, adopts thermofusible spigot when being connected with aluminium-plastic composite pipe, adopts metallic sheath and ring and working of plastics to be combined into integral body at the working of plastics outer wall.
Purpose of the present invention is realized by following technical measures.
The steel that is used for the connection of aluminium-plastic composite pipe pipeline is moulded the composite hot melt socket pipe member, the inwall (2) that is characterized in aluminium-plastic composite pipe (1) is connected with socket (4) with the spigot (5) of socket pipe member (6) with outer wall (3), the main body of socket pipe member (6) is working of plastics (10), the metallic sheath (8 that working of plastics (10) is complementary with shape, 11) and metal ring (7,9,12) fastening.
Being shaped as of socket pipe member (6) is straight-through, the pipe fitting of tooth or outer tooth inserts in elbow, threeway, four-way or the band metal.
The material of the main body working of plastics (10) of socket pipe member (6) is polyethylene or polypropylene.
The metallic sheath of socket pipe member (6) and the material of ring are stainless steel, aluminum alloy or Cuprum alloy.
The present invention has following advantage:
1. plastic-aluminum combined tube wall and main pipe body are same type of material, and be follow-up crosslinked no matter whether aluminium-plastic composite pipe inside and outside wall plastics carry out, and can both fuse into one behind the thermofusible spigot, thoroughly eradicated leakage problem;
2. pipe fitting is corrosion-resistant, health, and long service life, steel-plastic structure has been given very high withstand voltage properties and creep-resistant property, and Security is good, can satisfy the requirement that transports of hot and cold water, rock gas and other fluids fully;
3. the plastic-aluminum tube end is imbedded in the pipe fitting in the circular groove between socket behind the thermofusible spigot, and sealing has fully been avoided peeling off because of long period of soaking causes hot melt adhesive bonding layer in water;
4. volume is little, and is in light weight, the manufacturing process maturation, and final product price is cheap.Promote in China, remarkable economic efficiency and social benefit are arranged.
Four, description of drawings
Fig. 1 moulds compound socket pipe member connection diagram for aluminium-plastic composite pipe and steel.
Fig. 2 is socket pipe member main body working of plastics and stainless steel sleeve and the compound schematic representation of ring.
Five, embodiment
Carry out concrete description with the connection that embodiment moulds the composite hot melt socket pipe member to the steel that is used for the aluminium-plastic composite pipe pipeline and is connected with reference to the accompanying drawings, but can not be interpreted as limiting the scope of the invention.
As shown in Figure 1, aluminium-plastic composite pipe 1 makes the aluminium-plastic composite pipe that is in connection part by thermofusible spigot instrument (commercially available) inwall 2 and outer wall 3 are one with spigot 5 and the socket 4 fusing socket joints that steel is moulded composite hot melt socket pipe member 6 respectively, become tight whole after the cooling, achieve a fixed connection.
As shown in Figure 2, stainless steel sleeve 8,11 and stainless steel ring 7,9,12 that the main body working of plastics 10 usefulness shapes of thermofusible spigot pipe fitting 6 are coincide are sealed, and through punching press, fastening, make composite steel-plastic pipe fitting.
Claims (4)
1. a steel that is used for the connection of aluminium-plastic composite pipe pipeline is moulded the composite hot melt socket pipe member, the inwall (2) that it is characterized in that aluminium-plastic composite pipe (1) is connected with socket (4) with the spigot (5) of socket pipe member (6) with outer wall (3), the main body of socket pipe member (6) is working of plastics (10), the metallic sheath (8 that working of plastics (10) is complementary with shape, 11) and metal ring (7,9,12) fastening.
2. be used for steel that the aluminium-plastic composite pipe pipeline connects and mould composite hot melt and be in the charge of part according to claim 1 is described, it is characterized in that being shaped as of socket pipe member (6) is straight-through, the pipe fitting of tooth or outer tooth inserts in elbow, threeway, four-way or the band metal.
3. mould the composite hot melt socket pipe member according to the described steel that is used for the connection of aluminium-plastic composite pipe pipeline of claim 1, it is characterized in that the material of the main body working of plastics (10) of socket pipe member (6) is polyethylene or polypropylene.
