Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Fig. 2 is assembling drawing of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, comprise fixed part 1 and frizing portion 2.Fixed part 1 is hollow cylinder, in fixed part 1, is cavity, and the shape of described cavity can be cylindrical, also can be other shape.Fixed part 1 comprises tight lock part 11 and location division 12.Tight lock part 11 is located on location division 12.Tight lock part 11 outer walls are provided with the annular locking conical surface 111, have formed the up-small and down-big structure of tight lock part 11.Location division 12 outer walls are provided with annular orientational cone-shaped surface 121, have formed the up big and down small structure in location division 12.The locking conical surface 111 plays spacing effect.Orientational cone-shaped surface 121 plays the effect of location.Described location division 12 outer cones are faced the wall and meditated and are provided with sealed groove 122, and sealed groove 122 is for installing sealing ring.Described frizing portion 2 is a hollow cylinder, and structure that can be big up and small down also can be the structure of other shapes.Frizing portion 2 upper and lower two ends, inner side tilt respectively laterally, form up big and down small and upper little round platform chamber 21 of assigning, and the interior middle part of frizing portion 2 is a columniform oil pocket 22 of scraping.The cylindrical diameter of scraping oil pocket 22 is less than or equal to the minimum diameter in round platform chamber 21.Two round platform chambeies 21 act as the enlargement and contraction that facilitates frizing portion 2, make the easy stress deformation of frizing portion 2.The upper surface of described frizing portion 2 is connected with the lower surface of location division 12.The maximum outside diameter of 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 greater than the minimum diameter of frizing portion 2.Further preferably, the lower surface of location division 12 is provided with annular latch, and the upper surface of frizing portion 2 is provided with annular bayonet socket, and the upper surface of the lower surface of location division 12 and frizing portion 2 is by latch and bayonet socket clamping.Further preferably, the lower surface of the upper surface of frizing portion 2 and location division 12 links into an integrated entity by the method for sulfuration, and what make that frizing portion 12 is connected with location division 12 is more firm.Further preferably, described fixed part 1 is made by steel metalloid material, because the intensity of metal material is large, high pressure resistant, can be used for being fixed in well head.Further preferably, described frizing portion 2 is made by rubber-like elastic material, and rubber has elasticity, wear-resisting, high temperature resistant and good oil resistivity, also can adopt pps material to make.
As shown in Figure 1, 2, the setting inside at well head big four 8 of shown oil wiper.The inclined-plane 6 of jackscrew bolt 4 lower ends of the locking conical surface 111 of described annular and well head big four 8 sides fits, by instrument, rotate again the head 5 of jackscrew bolt 4 right-hand members, make inclined-plane 6 to the middle feeding of well head powerful being fitted on the conical surface of tight lock part 11, make 4 pairs of tight lock parts 11 of jackscrew bolt apply downward pressure, make thus tightly setting on the inclination conical surface 7 of well head big four 8 inwalls of described oil wiper orientational cone-shaped surface 121, 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 in oil pipe 3 outsides, 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, arranges to be like this convenient to the orientational cone-shaped surface 121 of location division 12 and the inclination conical surface 7 of well head big four 8 inwalls fits.The sealing ring of sealed groove 122 interior installations is for the annular space between sealed well inner sleeve and oil pipe 3.The maximum outside diameter of described frizing portion 2 is less than or equal to the minimum outer diameter of location division 12, arranges like this and is convenient to frizing portion 2 through the well head of well head big four 8 and enters inside.Two round platform chambeies 21 act as the enlargement and contraction that facilitates frizing portion 2, when oil pipe 3 enters, 2 expansions of frizing portion, when oil pipe 3 detaches, frizing portion 2 shrinks, and makes oil pipe 3 in frizing portion 2, enter easily and detach, and has avoided oil pipe 3 to be stuck in frizing portion 2 and has detached and have some setbacks.The minimum diameter of fixed part 1 is greater than the minimum diameter of frizing portion 2, and arrange like this and be convenient to interting of oil pipe 3, be that 3, oil pipe contacts with frizing portion 2.
As mentioned above, by the orientational cone-shaped surface 121 of location division 12 outer walls and the inclination conical surface 7 of well head big four 8, tightly fit together, the setting inside at well head big four 8.By the greasy dirt that oil pocket 22 strikes off oil pipe 3 of scraping of establishing in frizing portion 2.Annular sealed groove 122 is set on location division 12; In sealed groove 122, be provided with annular sealing ring, by sealing ring, seal the annular space between oil pipe 3 and sleeve pipe.As mentioned above, described oil wiper can be setting in well head, plays the effect of sealing and frizing.During installation, without other flange, ring gasket.Easy for installation, quick, operating efficiency improves greatly.Described oil wiper is simple in structure simultaneously, at the bottom of manufacturing cost.
