Abstract
This utility model is involved in a type of expansion pipe joint, which includes pipe joint body and adjusting nut, has the following features: the pipe joint body has a mouthpiece, on the internal surface of which an internal screw thread is provide; the adjusting nut has a through hole, on the external surface of which an external screw thread matched with the internal screw thread is provide; a seal ring is placed between the mouthpiece and adjusting nut; an endwise slipping telescopic regulation stem is placed in the pipe joint body, seal ring and adjusting nut. Pipe joint with this structure has the following benefit feature: 1, owing to the regulation stem, on the case of pipe heat expansion and cold contraction, the space between pipe and pipe joint can be automatic adjusted, so as to effectively prevent pipe from buckling distortion caused by heat expansion and cold contraction; 2, every components and parts of the pipe slide reasonably, and the seal ring has high compressibility, which will not cause leakage; 3, simple structure, easy to be assembled.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of telescopic tube joint that is applicable to that aluminium-plastic composite pipe and plastic tube connect.
Background technique
In people's daily production and life, various pipelines are necessary tool of transport of water, gas.Mostly pipeline in the past is metallic conduit, exists many shortcomings.Industry has emerged the upsurge that changes the conventional pipelines material both at home and abroad in recent years, present stage mature technique be to replace metallic conduit with aluminium-plastic composite pipe or plastic tube, the Placement of existing aluminium-plastic composite pipe or plastic tube adopts following two kinds usually: a kind of mode is to adopt hot melt or electric smelting method directly to connect, this Placement, under temperature variation causes situation that pipeline expands with heat and contract with cold, can not regulate voluntarily, cause the pipe bending distortion easily, its drawback is especially outstanding.Another kind of mode: adopt seal ring, by cooperating of pipeline and fitting internal and external threads, realize the connection of pipeline enclosure, this kind Placement deficiency is: sealing effect is undesirable, its main cause is the deficiency that walks of each assembly in actual applications, the compressibility of seal ring is not high, causes leakage easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pipeline junction that can prevent because of the diastrophic expansion pipe joint that expands with heat and contract with cold.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of expansion pipe joint, comprise pipe joint body, regulate nut, it is characterized in that: described pipe joint body is provided with interface, the interface internal surface is provided with internal thread, be shaped on through hole in the middle of the described adjusting nut, its outer surface is provided with the outside thread that matches with internal thread, be lined with seal ring between interface inner end and adjusting nut end, be with one section adjustable lever of sliding extension vertically in pipe joint body, seal ring and the adjusting nut.
Adopt the beneficial effect of the pipe joint of this structure: 1, owing to be provided with adjustable lever, under the situation that pipeline expands with heat and contract with cold, the spacing of tube and tube joint can be regulated automatically, thereby can prevent effectively that pipeline is because of the bending deflection of expanding with heat and contract with cold; 2, walking rationally of these each component of pipe joint, the compressibility height of seal ring can not cause leakage.3, simple in structure, be easy to the assembling.
In order to solve the problems of the technologies described above, the utility model also adopts following further technological scheme:
Be provided with boss in the described interface.This boss plays the effect of fixed seal ring.
The inner peripheral surface of described seal ring is provided with the stiffening rib of at least one circle projection.This stiffening rib plays the effect of reinforced seal.
Described seal ring is a silicon rubber loop.What the sealing circle adopted is heat-resisting, wear-resisting, the elastomeric silicon rubber loop of crossing through high temperature processing, and the influence that its material is not expanded with heat and contract with cold can prevent difference when too high or too low for temperature issuable leak of pipe joint because of thermal expansion coefficient.

Embodiment
As shown in Figure 1, the utility model is made up of pipe joint body 1, seal ring 6, adjusting nut 2 and adjustable lever 7.
Shown in Figure 2 is pipe joint body 1 sectional view.One end of pipe joint body 1 is provided with interface 3, and interface 3 internal surfaces are provided with internal thread 4, and interface 3 inner ends are provided with boss 8, and this boss 8 plays the effect of fixed seal ring 6.These interface 3 general metallic material that adopt are made, and it and pipe joint body 1 are injection molded into one, and the other end of pipe joint body 1 is the volume mouth 11 that is connected with pipeline.
Fig. 3 is for regulating nut 2 sectional views.Be shaped on manhole in the middle of regulating nut 2, its outer surface is provided with the outside thread 5 that matches with the internal thread 4 of interface 3.
Fig. 4 cuts open 6 views for seal ring.Sealing circle 6 linings are between interface 3 inner ends and adjusting nut 2 ends (referring to Fig. 6), and the inner peripheral surface of seal ring 6 is provided with the stiffening rib 9 of at least one circle projection.This stiffening rib 9 plays the effect of reinforced seal.What sealing circle 6 adopted is heat-resisting, wear-resisting, elastomeric silicon rubber loop, and the influence that its material is not expanded with heat and contract with cold can prevent difference when too high or too low for temperature issuable leak of pipe joint because of thermal expansion coefficient.
Fig. 5 is adjustable lever 5 sectional views.Be with one section adjustable lever 7 (referring to Fig. 6) of sliding extension vertically in pipe joint body 1, seal ring 6 and the adjusting nut 3, this adjustable lever 7 generally also adopts metallic material to make, one end of adjustable lever 7 is injected with is convenient to the plastic fastening 10 that pipeline connects, the termination of plastic fastening 10 is the volume mouth 12 that is connected with pipeline, the internal diameter of the external diameter of adjustable lever 7 and seal ring 6 is complementary, and the outer surface of adjustable lever 7 cooperates with the internal surface liquid sealing of seal ring 6.
Fig. 6 assembling of the present utility model back sectional view.During use, seal ring 6 is inserted interface 3 inner ends of pipe joint body 1, to regulate nut 2 is enclosed within on the adjustable lever 7, end with adjustable lever 7 inserts in seal ring 6 and the pipe joint body 1 then, screw and regulate nut 2, with pipeline respectively with the volume mouth 11 of pipe joint body 1, volume mouth 12 weldings of adjustable lever 7 plastic fastenings 10, at this moment, even meet temperature variation, pipeline expands with heat and contract with cold, under the effect of adjustable lever 7 sliding extensions, the spacing of pipeline junction can be regulated automatically, thereby can effectively prevent pipeline because of the bending deflection of expanding with heat and contract with cold, along with the rotation of regulating nut 2 advances, the end of adjusting nut 2 is crush seal circle 6 constantly, revolve tightly more, sealing effect is just good more, the compressibility height of seal ring, can not cause leakage, and not influence the flexible process that expands.
The foregoing description is only for the usefulness that the utility model is described, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, under the situation that does not break away from spirit and scope of the present utility model, can also make various variations and modification, so all technological schemes that are equal to also belong to category of the present utility model.
