The bearing is formed by combining and connecting a ball bearing and a thrust bearing.
The invention has the advantages that: 1. under normal working conditions, the abrasion parts, the sealing parts and the like can be quickly replaced without complicated disassembly operation, and the pressure resistance is high, safe and reliable. 2. The retainer ring, the large retainer ring sealing ring and the sealing ring form a sealing ring group for bearing high pressure, and the number of the sealing ring groups reaches three. The material of the large retainer ring sealing ring and the sealing ring is made of polytetrafluoroethylene or polyurethane, so that the large retainer ring sealing ring and the sealing ring are more wear-resistant and have better bearing capacity, the bearing capacity and the wear resistance of the water faucet are greatly improved, and the service life of the water faucet is prolonged. 3. The lower central tube is not directly connected with the shell, so that the abrasion of parts is reduced, the maintenance is convenient, the shell can be detached by unscrewing the protective cap, the easily abraded sealing element is installed in the shell, the parts are replaced without complex detaching work, and the maintenance efficiency is improved. 4. The load of the invention is 200kN, and the pressure is 105 Mpa. Small appearance, large drift diameter and large load.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Fig. 2 is an enlarged schematic view of the pressing sleeve position.
Detailed Description
Referring to fig. 1 and 2, the names of the components are as follows: the device comprises an upper central tube 1, a gooseneck tube assembly 2, a retainer ring 3, a central sleeve 4, a pressing sleeve 5, a protective cap 6, a large retainer ring sealing ring 7, a sealing ring 8, a pressing sleeve 9, a shell 10, a lower central tube 11, a spacer 12, a Y-shaped sealing ring 13, a bearing 14, an O-shaped sealing ring 15 and a thrust bearing 16.
Referring to fig. 1, the wellhead high-pressure circulation guide faucet comprises a gooseneck assembly 2, the gooseneck assembly 2 is connected with a shell 10, a lower central tube 11 is arranged in the shell 10, the lower central tube 11 penetrates through the shell 10 to be connected with the gooseneck assembly 2, and the lower central tube 11 is connected with the shell 10 through a bearing 14. The shell 10 is connected with the gooseneck assembly 2 through the protective cap 6; the lower central tube 11 is connected with the gooseneck tube assembly 2 through a plurality of pressing sleeves 5 and a pressing sleeve 9, each pressing sleeve 5 is combined and sealed with the lower central tube 11 through a sealing ring 8 and an O-shaped sealing ring 15, and each pressing sleeve 5 is sealed with the gooseneck tube assembly 2 through a large retainer ring sealing ring 7.
The bearing is formed by combining and connecting a ball bearing 14 and a thrust bearing 16, and meets the requirements of radial stress and axial stress.
Referring to fig. 2, the three parts of the retainer ring 3, the large retainer ring sealing ring 7 and the sealing ring 8 form a sealing ring group, and the parts are made of polytetrafluoroethylene or polyurethane. The polytetrafluoroethylene or polyurethane sealing ring has more outstanding advantages in the aspect of bearing pressure and has better wear resistance. And a standard O-shaped sealing ring 15 is arranged side by side with the parts of the retainer ring 3, the large retainer ring sealing ring 7 and the sealing ring 8, so that the double compression-resistant and wear-resistant effects are achieved. The wellhead high-pressure circulation guide tap can bear 105 Mpa. According to the oil and gas industry standard, the maximum working pressure values of the water taps with different loads are different, the load is less than or equal to 1000 kN-25 MPa, the load is less than or equal to 2000 kN-35 MPa, and the load of the water tap is 200kN and 105 MPa. The drift diameter is the pore size of the lower center tube 11. According to the standard of the water faucet, the small-tonnage water faucet is generally small in appearance, small in drift diameter and small in load; the large-tonnage faucet has large appearance, large drift diameter and large load; the application is that the appearance is little, the latus rectum is big, the load is big.
The use method or the working principle is as follows: the upper central tube 1, the gooseneck assembly 2, the protective cap 6 and the shell 10 are connected together through threads; the central sleeve 4 and the lower central tube 11 are connected together by screws. The casing 10 is provided with a Y-shaped sealing ring 13, a bearing 14, a pressing sleeve 5, a large retainer ring sealing ring 7, a sealing ring 8 and an O-shaped sealing ring 15 which play a sealing role for the assembled lower central tube 11, and the bearing 14 can ensure that the lower central tube 11 rotates smoothly.
The tubing or drill pipe is connected together by means of a thread on the lower base pipe 11. During well repair, the well repair liquid is injected into the well through the gooseneck assembly 2 and the lower central tube 11. The pressing sleeve 5 is provided with a large retainer ring sealing ring 7, a sealing ring 8 and an O-shaped sealing ring 15, so that the lower central tube 11 connected with the central sleeve 4 is enhanced in sealing, the bearing capacity and the wear resistance of the faucet are greatly improved, and the service life of the faucet is prolonged. The pressing sleeve 9 plays a limiting role in preventing the lower central tube 11 from longitudinally moving. When the operation is started, the downhole tool is rotated and the bearing 14 inside the tap enables the lower base pipe 11 to rotate smoothly without being worn. The other parts of the tap are not rotatable, except for the lower base pipe 11, the centre sleeve 4, which rotates with the downhole tool.
The foregoing description is only exemplary of the invention and is not intended to limit the spirit of the invention.
