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 nut. The rubber sleeve is arranged between the pipe fitting body and the nut. The nut is matched with an outer thread on one end of the pipe fitting body. An inner conical surface is arranged in a hole of the pipe fitting body. An inner conical surface is arranged in a hole of the nut. Two ends of the rubber sleeve are respectively provided with outer conical surfaces which are mutually matched with the inner conical surface in the pipe fitting body and the inner conical surface of the nut. 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, nut, rubber sleeve places between pipe fitting and the nut, nut matches with the outside thread of pipe fitting one end, has inner conical surface in the described pipe fitting body opening, have inner conical surface in the described nut bore, the two ends of described rubber sleeve have the male cone (strobilus masculinus) that matches with pipe fitting inner conical surface, nut inner conical surface respectively.
Above-mentioned multiunit tube joint, its characteristics are: install an awl cushion cover that matches with the nut inner conical surface additional in described nut inboard.
Above-mentioned multiunit tube joint, its characteristics are: the inner conical surface of described pipe fitting, nut, the male cone (strobilus masculinus) at described rubber sleeve two ends, the interior male cone (strobilus masculinus) of described awl cushion cover 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 nut and awl cushion cover 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. 1 is the utility model structural representation
Fig. 2 is the pipe fitting structural drawing
Fig. 3 is the rubber sleeve structural drawing
Fig. 4 is nut structure figure
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, nut 3 and awl cushion cover 4 in Fig. 1, pipe fitting 1 is an outside thread, inner conical surface is 10-80 ° in the hole, nut 3 internal threads and pipe fitting outside thread match, the inboard inner conical surface of nut thread is 10-80 °, the two ends of rubber sleeve 2 are respectively 10-80 ° the male cone (strobilus masculinus) that matches with pipe fitting inner conical surface, nut inner conical surface, and the inside and outside conical surface of awl cushion cover is 10-80 ° and matches with the nut 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, nut 3 and awl cushion cover 4; fastening nut 3; male cone (strobilus masculinus), the pipe fitting 1 at rubber sleeve 2 two ends, the inner conical surface of nut 3, the inside and outside conical surface of awl cushion cover are closely matched; the awl cushion cover can protect tubing directly not contact with nut; 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 5 of a small semicircle cylinder for the employing cylndrical surface is middle in Fig. 5, when fastening nut 3, play the double-layer seal effect.
The multiunit tube joint that the utility model provides can be used for the connection of two logical forms, and 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.
