Abstract
The utility model relates to a pipeline joint, which comprises a joint body provided with screw threads, wherein, at least one end of the joint body is provided with a connecting part, the outer side of which is provided with external screw threads, the connecting part form a conical shape, and the external circumference of the connecting part is provided with a reinforcing ring, the internal diameter of which is larger than the external diameter of the connecting part; convex teeth are arranged on the internal side wall of the reinforcing ring, and all convex teeth have same circumferential directions. When the pipeline joint is used, the reinforcing ring is sheathed on the external circumference of one end of pipe materials to be connected, two spanners are respectively used for acting on the reinforcing ring and the joint body, and the connecting part of the joint body is screwed in the inner wall of one end of the pipe materials. The utility model adopts a pipe screw thread structure on the pipeline joint, so the utility model has the advantages of good sealing performance, high-pressure and high-temperature resistance, anti-drawing performance, anti-bending and twisting performance, low cost and strong installing reliability, and the pipeline joint not only can be applied to the connection of metal pipe materials, such as copper pipes, aluminum pipes, etc., but also can be applied to the connection of non-metal pipe materials, such as rubber pipes, plastic pipes, etc., and is applied to the connection of plastic and plastic composite pipes, such as aluminum-plastic composite pipes, crosslinking polyethylene pipes, steel-plastic composite pipes, polypropylene pipes, etc.
Description
Technical field:
The utility model relates to a kind of pipeline parts, especially a kind of connecting element of pipeline, particularly a kind of pipe joint that adopts the conical surface to be threaded.
Background technique:
In the prior art, metal pipe such as copper, aluminium and nonmetal tubing such as rubber, plastics have been widely used in FLUID TRANSPORTATION.Use in the plastic tube aluminium-plastic composite pipe, crosslinked polyethylene pipe, steel-plastic composite pipe, polypropylene tube etc. are more generally arranged, wherein aluminium-plastic composite pipe have corrosion-resistant, high temperature resistant, high pressure resistant, antistatic, fluid resistance is little, be difficult for incrustation, heat-insulation and heat-preservation, be difficult for advantages such as embrittlement, in light weight, convenient in carrying, all than present widely used metal pipe and other plastic tubes remarkable advantages is arranged at aspects such as mechanical property, chemical property, prices.In the prior art, the pipe fitting Placement that is applied in the pipeline that aluminium-plastic composite pipe forms has Placements such as FERRULETYPE, compression type, clamp-press type, clamp band type, spigot and socket type.Metal pipe such as copper, aluminium has good-extensibility, corrosion-resistant, and in the prior art, the pipe fitting Placement that is applied in the pipeline that metal pipes such as copper, aluminium form has Placements such as enlarging, welding.
Summary of the invention:
Technical problem to be solved in the utility model is: in the prior art, adopt Placements such as FERRULETYPE, compression type, clamp-press type, clamp band type, spigot and socket type in the plastic-aluminum combined pipeline, because the characteristic of existing pipes pipeline connector, the barotolerance and the heat-resisting quantity of pipe joint are relatively poor, simultaneously tension pull out force, ability counter-bending and distortion are lower, manufacture cost is big, installation reliability is difficult to hold, influenced the normal use of plastic pipe, the pipe joint that has can only be used for exposed conduit and lay, can not be used for hidden pipe and lay, the phenomenon of plastic piping joint seepage often takes place.In the prior art, the pipe fitting Placement that is applied in the pipeline that metal pipes such as copper, aluminium form has Placements such as enlarging, welding.This Placement of enlarging ability counter-bending and distortion is lower.Weld this Placement install complicated, difficulty is big.
The utility model provides a kind of pipe joint for the technological scheme that above-mentioned technical problem adopted that solves in the prior art, described this pipe joint, comprise that is provided with a threaded fittings body, wherein, it is that arranged outside has externally threaded joint that described fittings body has an end at least, described joint is coniform, excircle at described joint is provided with a stiffening ring, the internal diameter of described stiffening ring is greater than the external diameter of described joint, the madial wall of described stiffening ring is provided with double wedge, and the circumferencial direction of all double wedges is identical.Further, can also cylinder or circular cone internal thread be set at the inwall of an end of described tubing, the joint with described pipe joint body is screwed into described tubing one end inwall again.Working procedure of the present utility model is: the excircle of an end that described stiffening ring is linked in the tubing of required connection, again with the joint of described pipe joint body by be screwed into the inwall of an end of tubing at described tubing one end inwall self tapping internal thread, perhaps be screwed into the cylinder or the circular cone internal thread of described tubing one end inwall.
The utility model and prior art contrast, because adopted pipe thread seal on pipe joint, worm tooth and screw thread alveolus are realized threaded closure, the expansion deformation that described this end of stiffening ring restriction tubing takes place, so sealability is better, and high pressure resistant high temperature, anti-pulling, counter-bending and distortion, low cost of manufacture, installation reliability is strong, and this connecting means not only can apply to the binding of metal pipes such as copper, aluminium, can also apply to the connection of nonmetal tubing such as rubber, plastics.Apply to being connected of plastics such as aluminium-plastic composite pipe, crosslinked polyethylene pipe, steel-plastic composite pipe, polypropylene tube and compound plastic pipe.
Description of drawings:
Fig. 1 is the schematic representation of a kind of pipe joint of the utility model.
Fig. 2 is the schematic representation of the stiffening ring in a kind of pipe joint of the utility model.
As shown in Figure 1, a kind of pipe joint of the utility model, comprise that is provided with a threaded fittings body 1, wherein, it is that arranged outside has externally threaded joint 2 that described fittings body 1 has an end at least, described joint 2 is coniform, excircle at described joint 2 is provided with a stiffening ring 3, the internal diameter of described stiffening ring 3 is greater than the external diameter of described joint 2, as shown in Figure 2, the madial wall of described stiffening ring 3 is provided with at least two double wedges 4, and the circumferencial direction of all double wedges 4 is identical.Working procedure of the present utility model is: the excircle that described stiffening ring 3 is linked in tubing 5 one ends of required connection, utilize two spanners to act on stiffening ring 3, fittings body 1 respectively during use, the joint 2 of fittings body 1 is screwed into an end inwall of tubing 5, the outside thread in described joint 2 outsides and pipe material inner wall internal thread are realized threaded closure, the expansion deformation that described stiffening ring 3 restriction tubing 5 these ends take place, the double wedge 4 of described stiffening ring 3 inboards prevents the displacement of tubing 5 at circumferencial direction simultaneously.In a preferred embodiment of the present utility model, can also the cylinder internal thread be set at the inwall of an end of described tubing, the joint with described pipe joint body is screwed into described tubing one end inwall again.
