Abstract
The utility model relates to a rotary joint for a roller of a continuous oil pipe, which belongs to the technical field of the rotary joint. The rotary joint for the roller of the continuous oil pipe consists of a wing type nut, a fixed pipe, a central spindle, a rotary pipe, a shell, a sealing ring, a rolling ball, a ball support frame and the like. A connecting device installed between the rotary pipeline part and the fixed pipeline part of the roller solves the problem of connection between the continuous oil pipe and the fixed high-pressure pipe on the rotating roller. The rotary joint for the roller of the continuous oil pipe has the characteristics of less operators, less ground facilities, low noise, small influence to the environment, high benefit and the like.
Description
Technical field
The utility model relates to a kind of swivel joint, relates in particular to a kind of coiled tubing cylinder swivel joint, belongs to the swivel joint technical field.
Background technique
The coiled tubing technology has become the perfect day by day new technology in petroleum gas field.Coiled tubing equipment needs earlier oil pipe to be put into the oil well bottom through injection head when work, and the operation material partly enters into coiled tubing through the high pressure pipe joint on the coiled tubing equipment then, finally gets to the shaft bottom operation.Coiled tubing is to link together with fixing high pressure pipe joint in operation and turnover oil well all the time, will solve like this coiled tubing on the cylinder of rotation with the high pressure pipe joint of fixing between connectivity problem.The defective of existing technology is a little less than the pilot pressure ability that big to reservoir damage, equipment is not easy problems such as installation, dismounting.
The model utility content
The utility model provides reliable, the widely used coiled tubing cylinder of a kind of running rotary joint device for solving deficiency of the prior art.The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of coiled tubing cylinder swivel joint, comprise aerofoil profile nut, fixing tube, mandrel, rotating pipe, housing, seal ring, rolling ball, ball supporting frame, and its special way is: L shaped hollow hole is arranged in the housing; And an end is a concave hole, and the non-spill nose end of housing is fixedly connected with the I-shaped fixed tube that is provided with endoporus, between housing and fixed tube seal ring is installed; Fixed tube on-fixed end is with the aerofoil profile nut; Housing spill nose end fixed installation mandrel, mandrel gos deep into shell ends has boss, and seal ring is installed in the gap between mandrel leading portion and housing; Gap between mandrel stage casing and housing is equipped with the rolling ball of band mesopore; Rolling ball is installed on the housing through the ball supporting frame, and the terminal retaining ring of mandrel is fixedly mounted on the housing, and J font swivelling pipe tail end is fixedly mounted on the mandrel; And and mandrel between be equipped with seal ring, the swivelling pipe the other end is with the aerofoil profile nut.
The beneficial effect of the utility model is: 1, easy to connect, the attachment portion is identical with common high pressure pipe joint Connecting format, is union and connects, and this swivel joint has two public union joints; 2, realize standardization and versatility, can be according to the different swivel joint of size apolegamy of high pressure pipe joint, also interchangeable use between the swivel joint of same size; 3, the rotation position adopts rolling ball contact between rotating part and the standing part, and rotational resistance is little, the using scope that has improved working life and equipped the field at oil; 4, the multiple tracks rubber seal is adopted in fixing and rotating part sealing, has also adopted seal with elastometic washer between the fixed connecting piece, and sealing is reliable, and is easy to maintenance.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described seal ring is protruding and sunk structure, Y shape convexity and sunk structure or a V-arrangement sunk structure of T shape.
Adopt the beneficial effect of above-mentioned further scheme to be, make that the sealing of swivel joint is better guaranteed, satisfy demand of practical production.

Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
In order further to disclose the technological scheme of the utility model, do detailed explanation below in conjunction with Figure of description.A kind of coiled tubing cylinder swivel joint (referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4) comprises aerofoil profile nut 1, fixing tube 2, mandrel 3, rotating pipe 4, housing 5, seal ring 6, rolling ball 7, ball supporting frame 8, and its special way is: L shaped hollow hole is arranged in the housing 5; And an end is a concave hole, and housing 5 non-spill nose ends are fixedly connected with the I-shaped fixed tube 2 that is provided with endoporus, and 2 of housing 5 and fixed tube are equipped with seal ring; Fixed tube 2 on-fixed ends are with aerofoil profile nut 1; Housing spill nose end fixed installation mandrel 3, mandrel 3 gos deep into shell ends has boss, and seal ring 6 is installed in the gap that mandrel 3 leading portions and housing are 5; The gap that mandrel 3 stage casings and housing are 5 is equipped with the rolling ball 7 of band mesopore; Rolling ball 7 is installed on the housing 5 through ball supporting frame 8, mandrel 3 terminal being fixedly mounted on the housing 5, and J font swivelling pipe 4 tail ends are fixedly mounted on the mandrel 3; And and 3 of mandrels be equipped with seal ring 6, swivelling pipe 4 the other ends are with the aerofoil profile nut.In actual use, aerofoil profile nut 1 is connected with manifold on the coiled tubing cylinder with fixing high pressure pipe joint respectively, between fixed tube 2 and the housing 5 for being fixedly connected; And adopting the seal ring sealing, also is to be fixedly connected and the seal ring sealing between mandrel 3 and the rotating pipe 4, during the coiled tubing rotation; Mandrel 3 and rotating pipe 4 rotate with cylinder, and fixing tube 2 is fixed with 5 of housings, and their relative movement realizes through rolling ball 7; Rolling ball 7 is supported by 8 conducts of ball supporting frame; What pass through because of equipment is high-pressure liquid, and Seal of Equipment property must guarantee that the main sealing of this equipment realizes through seal ring 6; Seal ring 6 can be T shape protruding and sunk structure, Y shape convexity and sunk structure or V-arrangement convexity and sunk structure, guarantees under various working, can both accomplish reliable sealing.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
