Description
Technical field
The utility model relates to a kind of pipe joint, specifically welding high pressure pipe line joint.
Background technique
Pipe joint is connecting pipeline or the part that is contained in by pipeline on hydraulic element in hydraulic system, pipeline connection generally uses the tratitional technologys such as welding, the operation of welding is various, require strict, the pipeline of special substance connects need use special equipment and auxiliary material, its cost of material, installation cost, experimentation cost is all higher, installation time is long, the impurity such as welding slag and harmful matter is produced in welding process, when some need to ensure to use in clean pipeline (nitrogen pipeline as precision type instrument), need strict clean after could use, at substantial time and expense.
Summary of the invention
For solving the problems of the technologies described above, the welding high pressure pipe line joint that the utility model provides can be used in the high pressure pipe line of high cleanliness, and can connect the pipeline of different tube diameters and material.
The technological scheme that the utility model adopts is: welding high pressure pipe line joint comprises adapter body and clamp sleeve, adapter body two ends outer wall has two stage steps structure, in the middle part of adapter body, outer wall has groove, middle part inwall arranges circular orientation rank, the adapter body at groove two ends has different internal diameters, compressed part is connected outside the two stage steps of adapter body, described compressed part inwall is provided with the first seal ring be parallel to each other, second seal ring and the 3rd seal ring, compressed part outer wall is provided with bulge loop, clamp sleeve is enclosed within compressed part outer wall, the structure matched with two stage steps is had inside clamp sleeve.
Described bulge loop has the identical center of circle with the 3rd seal ring.
Described high pressure pipe line joint is stainless steel.
The beneficial effects of the utility model are: welding high pressure pipe line joint of the present utility model has three seal rings, can be used in the connection of high pressure pipe line; It adopts clamp sleeve seal for pipe joints to be connected, without the need to using welding, without the need to carrying out processes and various process to pipeline and connection part thereof before installation, without the need to carrying out the processing of any mode, inspection and process to pipeline and connection part thereof after installation, only need after system pipeline have all connected, unification is carried out pressure testing and is checked, improve the working efficiency of 70%, greatly reduce cost of labor, and be suitable for needing to ensure in clean pipeline, as the nitrogen pipeline for precision type instrument; Pipe coupling two ends are set to different internal diameters, are applicable to all kinds of work, the people, the various outer diameter specification of building engineering and unlike material pipeline and carry the connection (except cast iron quality) of all kinds of medium pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high pressure pipe line joint;
Fig. 2 is the structural representation after the utility model high pressure pipe line joint and pipeline assemble.
In figure: 1. adapter body, 2. clamp sleeve, 3. groove, 4. two stage steps, 5. compressed part, 6. circular orientation rank, 7. bulge loop, 8. the first seal ring, 9. the second seal ring, 10. the 3rd seal ring, 11. pipelines, 12. scrobicular rings.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of welding high pressure pipe line joint, for stainless steel, comprise adapter body 1 and clamp sleeve 2, described adapter body 1 two ends outer wall has two stage steps 4 structure, in the middle part of described adapter body 1, outer wall has groove 3, middle part inwall arranges circular orientation rank 6, the adapter body 1 at described groove 3 two ends has different internal diameters, compressed part 5 is connected outside the two stage steps 4 of described adapter body 1, described compressed part 5 inwall is provided with the first seal ring 8 be parallel to each other, second seal ring 9 and the 3rd seal ring 10, compressed part 5 outer wall is provided with the bulge loop 7 with the 3rd seal ring 10 with phase concentric, described clamp sleeve 2 is enclosed within compressed part 5 outer wall, the structure matched with two stage steps 4 is had inside clamp sleeve 2.
In use, as shown in Figure 2, two pipelines 11 are inserted into respectively pipe coupling two ends inner, pipeline 11 is encountered circular orientation rank 6 and stops stretching into, at clamp sleeve 2 outer installment pressure exerting arrangement, Hydraulic power tools is used to apply external force to pressure exerting arrangement, produce axially inside external force, clamp sleeve 2 axial motion also distortion is reduced, the bulge loop 7 of extruding compressed part 5 outer wall, and further by extruding the first seal ring 8 of compressed part 5 inwall, second seal ring 9 and the 3rd seal ring 10 carry out the tube wall of extrusion pipe 11, tube wall extrudes scrobicular ring 12, produce interference fit and reach the effect be tightly connected.Because the internal diameter at pipe coupling two ends is different, the pipeline of different size, unlike material can be inserted.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
