(2) being sulfided with location division entirety by frizing portion so that whole oil wiper forms an entirety, structure is firm, firm.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention.
Fig. 2 is the installation diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As it is shown in figure 1, include fixed part 1 and frizing portion 2. Fixed part 1 is hollow cylinder, is cavity in fixed part 1, and the shape of described cavity can be cylindrical, it is possible to for other shape. Fixed part 1 includes tight lock part 11 and location division 12. Tight lock part 11 is located on location division 12. Tight lock part 11 outer wall is provided with the locking conical surface 111 of annular, constitutes the structure that tight lock part 11 is up-small and down-big. Location division 12 outer wall is provided with the orientational cone-shaped surface 121 of annular, constitutes the structure that location division 12 is up big and down small. The locking conical surface 111 plays spacing effect. Orientational cone-shaped surface 121 plays the effect of location. Described location division 12 outer cone is faced the wall and meditated and is provided with sealed groove 122, and sealed groove 122 is used for installing sealing ring. Described frizing portion 2 is a hollow cylinder, structure that can be big up and small down, it is possible to for the structure of other shapes. Inside frizing portion 2, upper and lower two ends tilt respectively laterally, form the up big and down small and upper little round platform chamber 21 assigned, and in frizing portion 2, middle part is one and cylindrical scrapes oil pocket 22. Cylinder scrapes the diameter minimum diameter less than or equal to round platform chamber 21 of oil pocket 22. Two round platform chambeies 21 act as the expansion and contraction that facilitate frizing portion 2, make the easy stress deformation in frizing portion 2. The upper surface in described frizing portion 2 is connected with the lower surface of location division 12. The maximum outside diameter in described frizing portion 2 is less than or equal to the minimum outer diameter of location division 12. The minimum diameter of fixed part 1 is more than the minimum diameter in frizing portion 2. It is preferred that, the lower surface of location division 12 is provided with the latch of annular, and the upper surface in frizing portion 2 is provided with the bayonet socket of annular, the lower surface of location division 12 and the upper surface in frizing portion 2 by latch and bayonet socket clamping. It is preferred that, the upper surface in frizing portion 2 and the lower surface of location division 12 are linked into an integrated entity by the method vulcanized, and what make that frizing portion 12 and location division 12 connect is more firm. It is preferred that, described fixed part 1 is made up of steel metalloid material, owing to the intensity of metal material is big, high pressure resistant, can be used for being fixed in well head. It is preferred that, described frizing portion 2 is made up of rubber-like elastic material, and rubber has elasticity, wear-resisting, high temperature resistant and excellent oil resistivity, it would however also be possible to employ pps material is made.
As shown in Figure 1, 2, it is shown that the setting inside at well head big four 8 of oil wiper.The inclined-plane 6 of the locking conical surface 111 of described annular and jackscrew bolt 4 lower end of well head big four 8 side fits, the head 5 of jackscrew bolt 4 right-hand member is rotated again through instrument, inclined-plane 6 is made to be fitted on the conical surface of tight lock part 11 to the middle feeding of well head brute force, make jackscrew bolt 4 that tight lock part 11 is applied downward pressure, thus make described oil wiper orientational cone-shaped surface 121 tightly setting on the inclination conical surface 7 of well head big four 8 inwall, then make the setting inside at well head big four 8 of described oil wiper. The oil pocket 22 of scraping of described frizing portion interior cylindrical contacts with oil pipe 3, not only can strike off the greasy dirt outside oil pipe 3, can play the function of high pressure sealing simultaneously. The maximum outside diameter of tight lock part 11 is less than or equal to the maximum outside diameter of location division 12, and the inclination conical surface 7 so arranging the orientational cone-shaped surface 121 and well head big four 8 inwall of being easy to location division 12 fits. The sealing ring installed in sealed groove 122 is for sealing the annular space between well inner sleeve and oil pipe 3. The maximum outside diameter in described frizing portion 2, less than or equal to the minimum outer diameter of location division 12, so arranges the well head being easy to frizing portion 2 traverse well head big four 8 and enters inside. Two round platform chambeies 21 act as the expansion and contraction that facilitate frizing portion 2, when oil pipe 3 enters, frizing portion 2 expands, when oil pipe 3 detaches, frizing portion 2 shrinks, make oil pipe 3 enter easily in frizing portion 2 and detach, it is to avoid oil pipe 3 is stuck in frizing portion 2 and detaches has some setbacks. The minimum diameter of fixed part 1, more than the minimum diameter in frizing portion 2, so arranges and is easy to interting of oil pipe 3, be that 3, oil pipe contacts with frizing portion 2.
As it has been described above, tightly fit together by the orientational cone-shaped surface 121 of location division 12 outer wall and the inclination conical surface 7 of well head big four 8, the setting inside at well head big four 8. The greasy dirt of oil pipe 3 is struck off by the oil pocket 22 of scraping set in frizing portion 2. Location division 12 arranges the sealed groove 122 of annular; In sealed groove 122, it is provided with the sealing ring of annular, is sealed the annular space between oil pipe 3 and sleeve pipe by sealing ring. As it has been described above, described oil wiper can be setting in well head, play the effect sealed with frizing. During installation, it is not necessary to other flange, ring gasket. Easy for installation, quick, working performance improves greatly. Described oil wiper simple in construction simultaneously, at the bottom of manufacturing cost.
