Abstract
The utility model discloses a tap for oilfield workover, including casing (1), center tube (2), switching pipe (3), its characterized in that: the sectional type structure is adopted in casing (1), including load shell (11), positioning disk (12), load shell (11) are connected with switching pipe (3), be provided with on switching pipe (3) with the communicating swan -neck bent tube of casing inner chamber (7), center tube (2) set up at the casing inner chamber, cooperate with load shell (11), and positioning disk (12) cover is fixed on center tube (2) and with load shell (11) mutually. The utility model has the advantages of compact structure, maintenance convenience, bearing capacity are greatly, the friction is little, the center tube rotational speed high, the leakproofness is good.
Description
Technical field
This utility model relates to a kind of oil well repairing operation faucet, the well-flushing being particularly suited in oil exploitation, the set workover treatment faucet such as milling, sand washing.
Background technology
Workover treatment faucet is one of important tool of well-flushing, the set workover treatment such as milling, sand washing, and it is a kind of crossover tool connecting drill string with the system of lifting, generally comprises rotating part and non-rotating structure.Rotating part is with central canal, and non-rotating structure is load body, and with the rotary hose bridge piece communicated with its inner chamber；Bearing it is provided with between rotating part and non-rotating structure.In the prior art, the number of bearings between rotating part and load body is less, and position of bearings is arranged unreasonable, and bearing capacity is limited, and friction is serious, and central canal rotating speed is relatively low, it is difficult to meet job requirements.Rotary hose bridge piece location arrangements is unreasonable, and rotary hose easily gives a discount damage.
Summary of the invention
Goal of the invention: this utility model purpose is for the deficiencies in the prior art, it is provided that a kind of high rotating speed, low friction, the set milling faucet of high-bearing capacity.
Technical scheme: the open a kind of oil well repairing operation faucet of this utility model, including housing, central canal, transfer tube, bearing, packing, it is characterized in that: described housing uses segmentation structure, and including load shell, location dish, described load shell is connected with transfer tube, location dish；Being provided with the swan-neck bent tube communicated with housing cavity on described transfer tube, described central canal is arranged on housing cavity, matches with load shell, and positioning disk sleeve fixes on central canal and with load shell.By using housing segments formula structure to design, the convenient installation position arranging thrust bearing between housing and central canal, multiple installation position can be arranged as required, improve bearing capacity greatly；Facilitate the processing of each parts simultaneously, assemble and safeguard.
As further improvement of the utility model, described oil well repairing operation faucet also includes that seals a pipe, and sealing pipe matches to merge with transfer tube and is threadably secured with central canal；Seal and be provided with packing groove between pipe and central canal, transfer tube.Seal pipe by individually designed, can conveniently arrange position and the quantity of packing groove, improve sealing effectiveness, the design of center of reduction pipe simultaneously and processing.
As further improvement of the utility model, it is provided with radial bearing and thrust bearing, radial bearing and thrust bearing between described central canal and housing with the use of improving bearing capacity the friction reducing between central canal and housing, improves the available rotating speed of central canal.
As further improvement of the utility model, described load shell is threadably secured with transfer tube, is additionally provided with anti-relaxed, effectively prevents connection loosing between load shell and transfer tube.
As further improvement of the utility model, the water inlet direction of described bridge piece is parallel with central canal, makes current unobstructed, prevents rotary hose from giving a discount when water flowing damage.
As further improvement of the utility model, making described bridge piece is disposable seamless-molding bend pipe, to strengthen the intensity of bridge piece.
Beneficial effect: this utility model used employing housing segments formula structure to design, convenient employing thrust bearing, improve bearing load, simultaneously with the use of radial bearing, reduce the friction between housing and central canal, it is effectively increased the rotating speed of central canal and wear-resistant service life, makes this utility model compact conformation, light weight, easy to maintenance simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of described oil well repairing operation faucet；
In figure, each component names is: 1, housing, 2, central canal, 3, transfer tube, 4, seal pipe, 5, O type packing, 6, packing groove, 7, swan-neck bent tube, 8, thrust bearing, 9, radial bearing, 11, load shell, 12, location dish, 13, anti-loose spot, and 14 screws.
Detailed description of the invention
Below by accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment 1 :A kind of oil well repairing operation faucet, including housing 1, central canal 2, transfer tube 3, housing 1 uses segmentation structure, and including load shell 11, location dish 12, load shell 11 is threaded connection with switching coil pipe 3, location dish 12；The swan-neck bent tube 7 communicated with housing 1 inner chamber it is provided with on transfer tube 3, central canal 2 is arranged on the inner chamber of housing 1, match with load shell 11, convex shoulder it is provided with on central canal, thrust bearing 8 it is provided with between convex shoulder and load shell, between convex shoulder and transfer tube, it is provided with radial bearing 9, between load shell 11 and central canal 2, is provided with packing groove 6.Seal pipe 4 be connected with transfer tube 3 and be threadably secured with central canal 2；Seal and be provided with packing groove 6 between pipe and central canal, transfer tube.Location dish 12 is connected by screw with load shell 11, is additionally provided with anti-loose spot 13 between housing 1 and transfer tube 3, and anti-loose spot 13 is fixed on transfer tube by screw 14.Employing segmentation structure designs, and can simplify the design of each parts, convenient processing, the most also optimize assembling and the operation safeguarded；Facilitate simultaneously and can arrange multiple bearing installation position as required, improve bearing capacity and also reduce friction.Seal pipe by individually designed, can conveniently arrange position and the quantity of packing groove, improve sealing effectiveness, the design of center of reduction pipe simultaneously and processing.By arranging anti-loose spot, prevent transfer tube 3 from loosening with load shell 11.Parallel with central canal by the water inlet direction that makes gooseneck bend pipe, it is ensured that current are unobstructed, prevent rotary hose from giving a discount when water flowing damage.
Although as it has been described above, represented and described the present invention with reference to specific preferred embodiment, but it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention premise defined without departing from claims, can various changes can be made in the form and details to it.
