Abstract
The utility model discloses a pipeline connector convenient to assemble and disassemble. The pipeline connector convenient to assemble and disassemble comprises a connector body (1) which is cylindrical, a circle of arc-shaped grooves (2) of an indent structure are arranged in the circumferential face of the connector body (1), a connecting shaft (6) is connected on the lower end face of the connector body (1), a plurality of grooves (3) are evenly formed on the circumferential face of the connecting shaft (6), a key (4) is formed between a groove (3) and another groove (3), and the grooves (3) and the keys (4) are arranged alternately with each other to form a teeth-shaped connecting structure, and through holes (5) are formed in the connector body (1) and the connecting shaft (6). The pipeline connector convenient to assemble and disassemble has the advantages of being simple in structure, convenient to assemble and disassemble, and capable of improving working efficiency, and reducing cost.
Description
Technical field
The utility model relates to the pipe coupling that a kind of petroleum pipeline is used, and specifically is a kind of easy-to-dismount pipe coupling.
Background technique
In petroleum production and transportation process, can use many oil pipes, oil pipe is arranged intricate, and length is longer generally speaking, also have the place of many bendings, so need using joint, the connection between the oil pipe connects to reduce tubing length and floor space, present oil connection adopts double thread screw or flange to connect mostly, when interconnecting between the oil pipe or dismantling, need special tool that the oil pipe rotation just can be finished, operator are time-consuming, effort, simultaneously, double thread screw needs very high degree of adaptability when connecting, so not only reduced working efficiency, and having increased cost also influences job schedule simultaneously.
The model utility content
Problem to be solved in the utility model provides a kind of easy-to-dismount pipe coupling, is used for solving oil connection loading and unloading inconvenience and the high problem of cost.
The technological scheme that the utility model provides is: easy-to-dismount pipe coupling, comprise main body, main body is cylindrical, described main body is provided with the curve bath that a circle is concave inward structure at circumferential surface, described main body lower end surface is connected with coupling shaft, also is evenly distributed with several grooves on the coupling shaft circumferential surface, forms key between groove and the groove, described groove and key are alternately arranged with each other and constitute the linkage structure of profile of tooth, also are provided with through hole in described main body and the coupling shaft.
Described coupling shaft lower end surface also is provided with seal groove.Insert seal ring in the seal groove and be used for sealing usefulness when joint is connected with the oil pipe connecting end, avoid oil pipe to reveal and cause damage.Can insert a plurality of seal rings according to required.
Described groove is provided with eight altogether.The connecting head of petroleum pipeline is connected with joint, the linkage structure that is complementary by the tooth-shape structure of forming with groove and key on the connecting head, the two reaches with the cooperation of key by groove and is connected effect, and simultaneously, the gripping mechanism on the connecting head is clamped in the curve bath of joint pipeline and joint are tightened.
The degree of depth of described curve bath is less than or equal to 3 centimetres.The main body wall thickness at curve bath place was thinner when the degree of depth of curve bath was excessive, and its intensity will be affected, and fracture occurred easily, thus the degree of depth of curve bath be less than or equal to 3 centimetres can be maximum the requirement of strength at curve bath place.
Described main body away from the length of curve bath one end of coupling shaft more than or equal to 5 centimetres.Main body is prone to after main body connects when too short away from the length of curve bath one end of coupling shaft leaks or connects problem of unstable, has brought inconvenience to use, thus main body away from the length of curve bath one end of coupling shaft more than or equal to 5 centimetres.
Described main body and coupling shaft all adopt 40cr alloyed steel material.40cr alloyed steel moderate cost, easy processing can obtain certain toughness, plasticity and wear resistance after suitable heat treatment, have best comprehensive mechanical property, can strengthen the overall performance of main body and coupling shaft, thus can whole intensity and working life of improving workpiece.
Advantage of the present utility model is: this easy-to-dismount pipe coupling of the utility model design, and not only simple in structure, easy to loading and unloading, improved working efficiency, cost reduces.

Label among the figure is expressed as respectively: 1, main body; 2, curve bath; 3, groove; 4, key; 5, through hole; 6, coupling shaft; 7, seal groove.
Embodiment
Embodiment
Referring to Fig. 1, Fig. 2, easy-to-dismount pipe coupling, comprise main body 1, main body 1 is cylindrical, and described main body 1 is provided with the curve bath 2 that a circle is concave inward structure at circumferential surface, and described main body 1 lower end surface is connected with coupling shaft 6, also be evenly distributed with several grooves 3 on coupling shaft 6 circumferential surfacies, form key 4 between groove 3 and the groove 3, described groove 3 is alternately arranged with each other with key 4 and constitutes the linkage structure of profile of tooth, also is provided with through hole 5 in described main body 1 and the coupling shaft 6.
Described coupling shaft lower end surface also is provided with seal groove 7.
Described groove 3 is provided with eight altogether.
The degree of depth of described curve bath 2 is less than or equal to 3 centimetres.
Described main body 1 away from the length of curve bath 2 one ends of coupling shaft 6 more than or equal to 5 centimetres.
Described main body 1 and coupling shaft 6 all adopt 40cr alloyed steel material.
In use, earlier will put into seal ring in the seal groove 7, groove 3 with joint is connected with the pipeline connecting head with the linkage structure that key 4 constitutes again, the structure of the long splice conception coupling that constitutes with groove 3 and key 4 is arranged on the pipeline connecting head, and the chucking structure with the connecting head clamp device is clamped in the curve bath 2 and can uses at last.During clamping, thereby also can place one or more seal ring enhanced leaktightness effects at the platform of coupling shaft 4 and main body 1 joint.
The be alternately arranged with each other linkage structure that constitutes profile of tooth of groove 3 and key 4 has replaced traditional being threaded and has been connected with flange, and not only structural stability is not fragile, and installs quick and conveniently, has saved time and cost.
Can well realize the utility model as mentioned above.
