Description

Be used for the rapid pipe joint that petroleum oil connects

Technical field

The utility model relates to a kind of oil connection, specifically is a kind of rapid pipe joint for the petroleum oil connection.

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 rapid pipe joint for the petroleum oil connection, and being used for solving the oil connection loading and unloading wastes time and energy, requires the high and easy problem of damaging.

The technological scheme that the utility model provides is: be used for the rapid pipe joint that petroleum oil connects, comprise adapter body, the vertical end face of adapter body is six identical square, described adapter body lower end surface connecting thread joint, inipple is provided with outside thread, described adapter body upper-end surface jointing clip joint, the vertical end face of thimble connector is provided with the curve bath of indent, thimble connector is seal shaft in the upper end of curve bath, the seal shaft circumferential end surfaces is provided with the seal groove I, also has the through hole that runs through thimble connector and inipple centered by the adapter body axis.

Described inipple and thimble connector joint also are provided with the seal groove II.Insert seal ring in the seal groove II and be used for sealing usefulness when inipple is connected with the oil pipe connecting end, avoid oil pipe to reveal and cause damage.

Also be provided with buckle in arbitrary square of the vertical end face of described adapter body.Establish through hole in the buckle, after rapid pipe joint connects, can pass buckle by link rapid pipe joint is fixed on desired location, guarantee oil pipe in position, avoid oil pipe because of reasons such as gravity distortion or fracture, the minimizing accident takes place, simultaneously, also oil pipe can be linked together required oil pipe by links such as steel wires, thereby each oil pipe is concentrated, avoided oil pipe to disperse and cause the expansion of the chaotic and floor space of pipeline, be convenient to staff's management and keep in repair.

The degree of depth of described curve bath is the 1/2-1/3 of seal shaft radius.The seal shaft 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 occurred fracture easily, so the degree of depth of curve bath can not be excessive.

The length of the seal shaft of described seal groove I upper end is more than or equal to 3 centimetres.Seal shaft connected the joint, back and is prone to and leaks or connect problem of unstable when the length of the seal shaft of seal groove I upper end was too short, had brought inconvenience to use, so the length of the seal shaft of seal groove I upper end is more than or equal to 3 centimetres.

Advantage of the present utility model is: this rapid pipe joint for the petroleum oil connection of the utility model design, not only simple in structure, loading and unloading and easy to maintenance have improved Security and the working efficiency of oil pipe management.

Description of drawings

Fig. 1 is front view of the present utility model.

Fig. 2 is structural representation of the present utility model.

Label among the figure is expressed as respectively: 1, through hole; 2, seal groove I; 3, seal shaft; 4, curve bath; 5, adapter body; 6, seal groove II; 7, inipple; 8, thimble connector; 9, buckle.

Embodiment

Referring to Fig. 1, Fig. 2, be used for the rapid pipe joint that petroleum oil connects, comprise adapter body 5, adapter body 5 vertical end faces are six identical square, described adapter body 5 lower end surface connecting thread joints 7, inipple 7 is provided with outside thread, described adapter body 5 upper-end surface jointing clip joints 8, thimble connector 8 vertical end faces are provided with the curve bath 4 of indent, thimble connector 8 is seal shaft 3 in the upper end of curve bath 4, seal shaft 3 circumferential end surfaces are provided with seal groove I 2, also have the through hole 1 that runs through thimble connector 8 and inipple 7 centered by adapter body 5 axis.

Described inipple 7 also is provided with seal groove II 6 with thimble connector 8 joints.

Also be provided with buckle 9 in arbitrary square of described adapter body 5 vertical end faces.

The degree of depth of described curve bath 4 is the 1/2-1/3 of seal shaft 3 radiuses.

The length of the seal shaft 3 of described seal groove I 2 upper ends is more than or equal to 3 centimetres.

In use, insert seal ring in the seal groove II 6, tubing round thread joint 7 one ends that needs are connected are connected with oil pipe and screw, insert seal ring in the seal groove I 2 in the other end seal shaft 3 of rapid pipe joint, outside the oil pipe cover and thimble connector 8 with required connection, by the arc clip chucking that mates with arc groove 4 on the oil pipe of required connection, arc groove 4 and arc clip are finished whole connection and can be used by cooperating chucking.

Can pass buckle 9 by link after buckle 9 makes rapid pipe joint connect rapid pipe joint is fixed on desired location, guarantee oil pipe in position, avoid oil pipe because of reasons such as gravity distortion or fracture, the minimizing accident takes place, simultaneously, also oil pipe can be linked together required oil pipe by links such as steel wires, thereby each oil pipe is concentrated, avoid oil pipe to disperse and cause the expansion of the chaotic and floor space of pipeline, be convenient to staff's management and keep in repair.

Arc groove 4 makes only need be clamped on when rapid pipe joint is connected with oil pipe in the arc groove 4 can finish connection, and the radian by arc groove 4 reaches chucking and connects effect, and is simple and convenient, practical.

Seal groove II 6 with can reach good sealing effect after seal groove I 2 makes rapid pipe joint be connected, be not prone to leakage, structure is not fragile simultaneously, as occur leaking or sealing when not enough, only need to change seal ring or increase seal ring to get final product, sealing is simple, good airproof performance.

Can well realize the utility model as mentioned above.
