Abstract
The utility model relates to a composite pipe joint. The composite pipe joint is characterized in that the composite pipe joint is composed of a pipe fitting body, a rubber sleeve, and a hollow screw plug. The rubber sleeve is arranged between the pipe fitting body and the hollow screw plug. The hollow screw plug is matched with an inner thread on one end of the pipe fitting body. An inner conical surface is arranged in a hole of the pipe fitting body. And an inner conical surface is arranged in a hole of the hollow screw plug. Two ends of the rubber sleeve are respectively provided with outer conical surfaces which are matched with the inner conical surface of the pipe fitting body and the inner conical surface of the hollow screw plug. The composite pipe joint provided by the utility model has simple structure, less component, and good sealing effect. When the composite pipe joint is assembled, an end opening of a pipe material does not need any modification, liquid or gas flowing through the pipe material is not contacted with an iron and steel material, and the pollution to water or other liquid in a pipeline due to the rusting of the iron and steel material is avoided.
Description
The utility model relates to the pipe fitting field, relates in particular to the connection of composite pipe.
Present domestic similar pipe joint, one of them main part all is to utilize copper or stainless steel, has the snap ring or the collar of breach on the cylndrical surface, the housing type pipe coupling structure of utilizing its elasticity and shrinking chucking tubing, this type of structural group member is more, and technological requirement is also high.
The purpose of this utility model provide a kind of simple in structure, assembly is few, good sealing effect, multiunit tube joint easy to install and use.
The utility model is achieved through the following technical solutions:
A kind of multiunit tube joint, its characteristics are: it is made up of pipe fitting, rubber sleeve, hollow plug screw, rubber sleeve places between pipe fitting and the hollow plug screw, the hollow plug screw matches with the internal thread of pipe fitting one end, has inner conical surface in the described pipe fitting body opening, have inner conical surface in the described hollow spiro pluging hole, the two ends of described rubber sleeve have the male cone (strobilus masculinus) that matches with pipe fitting inner conical surface, hollow plug screw inner conical surface respectively.
Above-mentioned multiunit tube joint, its characteristics are: the inner conical surface of described pipe fitting and hollow plug screw, the male cone (strobilus masculinus) at described rubber sleeve two ends is 10-80 °.
Above-mentioned multiunit tube joint, its characteristics are: protrude a small half of cylndrical surface in the middle of the rubber sleeve cylndrical surface, the rubber sleeve two ends are male cone (strobilus masculinus).
Above-mentioned multiunit tube joint, its characteristics are: described pipe fitting can be the elbow that has angle.
Above-mentioned multiunit tube joint, its characteristics are: the material of described pipe fitting can be cast steel, cast iron, copper, can be that metal adds that the internal layer lining is moulded or overall plastic, the material of described rubber sleeve is nitrile butadiene rubber, silicone rubber or plastics, and the material of described hollow plug screw is metal or plastics.
After adopting such scheme, the multiunit tube joint that the utility model provides is simple in structure, assembly is few, good sealing effect, port to tubing during assembling need not anyly be revised, and the liquid or the gas that flow through tubing do not contact ferrous materials, avoid getting rusty of invar iron material and pollute ducted water or other liquid.
Below in conjunction with Figure of description the utility model is further specified

Fig. 2 is the pipe fitting structural drawing
Fig. 3 is the rubber sleeve structural drawing
Fig. 4 is a hollow plug screw structural drawing
Fig. 5 is the another kind of structural representation of rubber sleeve
The utility model multiunit tube joint is made up of pipe fitting 1, rubber sleeve 2, hollow plug screw 3 in Fig. 1, pipe fitting 1 port is an internal thread, inner conical surface is 10-80 ° in the hole, the internal thread of outside thread on the hollow plug screw 3 and pipe fitting 1 matches, inner conical surface is 10-80 ° in the hole, and the two ends of rubber sleeve 2 are respectively 10-80 ° the male cone (strobilus masculinus) that matches with pipe fitting inner conical surface and hollow plug screw inner conical surface.Implementation procedure of the present utility model is as follows: al-plastics composite pipe or overall plastic tubing are passed in the hole of pipe fitting 1, rubber sleeve 2 and hollow plug screw 3, tighten plug screw 3, the male cone (strobilus masculinus) at rubber sleeve 2 two ends and the inner conical surface of pipe fitting 1 and hollow plug screw 3 are closely matched, this moment, the internal surface and the frictional force between pipe outer surface in rubber sleeve 2 holes tightened tubing effectively, thereby reached the sealing of tubing.
When another one embodiment of the present utility model is protruded the rubber sleeve 4 of a small semicircle cylinder for the employing cylndrical surface is middle in Fig. 5, when tightening plug screw 3, play the double-layer seal effect.
The utility model pipe joint can be used for the connection of two logical forms, the elbow of straight-through or different amount.Can be used for the connection of threeway form or the connection of four-way form.In the above-described embodiments, the connected tubing bore of every end can be identical or different, and every end can be a structure of the present utility model, also can be to be structure of the present utility model more than an end or the end, and other ends are arbitrary structures.
The systems such as hot and cold delivery (pipe) line system, purified water pipe-line system, flooring radiation pipe-line system and solar energy pipeline that the utility model multiunit tube joint is used for engineering construction replace the caliber that crosses the zinc steel pipe more than 12 millimeters al-plastics composite pipe or overall plastic tubing in be connected good sealing effect.
