Description
Technical field
The utility model relates to the design field of high pressure water injection valve bushing drawer.
Background technology
High pressure valve (the more than big orifice 2 inch) major part that oil-field flooding is commonly used is stop valve in the form of piston, in use, because corrosion and High-Pressure Water wash away, seal with buss face, sealing ring or valve seat damage is caused, cause valve to be missed, have a strong impact on water filling pump efficiency.If lining or valve seat damage just need integral replacing valve, maintenance cost increases, complicated construction technique.
Utility model content
The utility model object is for above problem, provides a kind of high pressure water injection valve bushing drawer reducing cost, easy construction.
The utility model comprises the tool body of hollow, screw rod of choosing, taper bush; Along uniform six pin holes of described tool body outer periphery, in each pin hole, arrange pin of choosing respectively, one end that each pin of choosing is arranged at tool body inside is equipped with the positive stop lug boss with pin hole apertures; Be nested with return spring respectively in the periphery of each pin of choosing, one end of each described return spring is arranged at the below of the positive stop lug boss of corresponding pin of choosing respectively, and the other end is fixedly connected with pin hole inwall; At two end faces of tool body, the first through hole and the second through hole are axially set respectively; Described first through hole and the second through hole on the same axis and communicate, described in screw rod of choosing arrange through the first through hole and the second through hole successively, described in screw rod of choosing connect the first locking nut for location through the threaded one end of the second through hole; Described taper bush can move up and down formula and be nested with outside screw rod of choosing, and described taper bush comprises the cone-shaped ejecting block that bush body and disjunctor are arranged on bush body one end; Described cone-shaped ejecting block is equipped with in the second through hole, and the pin that promotes when described cone-shaped ejecting block is mobile to tool body inside to choose outwards ejects; The body of rod of described taper bush away from the screw rod of choosing of cone-shaped ejecting block one end is threaded the second locking nut for location; Also be provided with seat board of choosing at described screw rod of choosing away from one end of tool body, the 3rd locking nut that described the choose screw rod of seat board away from the second locking nut side of choosing is threaded is for location.
Drawer is put into valve bushing by the utility model in use, precession second locking nut allow choose pin eject, enter valve bushing apopore.Install at afterbody backing plate of choosing, valve bushing can be extracted by slow circumvolve nut of choosing.The utility model is simple and reasonable, easy to use, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises the tool body 1 of hollow, screw rod 2 of choosing, taper bush 3; Along uniform six pin holes 4 of tool body 1 outer periphery, in each pin hole 4, arrange pin 5 of choosing respectively, one end that each pin 5 of choosing is arranged at tool body 1 inside is equipped with the positive stop lug boss 5-1 with pin hole 4 apertures; Be nested with return spring 6 respectively in the periphery of each pin 5 of choosing, one end of each return spring 6 is arranged at the below of the positive stop lug boss 5-1 of corresponding pin 5 of choosing respectively, and the other end is fixedly connected with pin hole 4 inwall; At two end faces of tool body 1, the first through hole 7 and the second through hole 8 is axially set respectively; On the same axis and communicate, screw rod 2 of choosing is arranged through the first through hole 7 and the second through hole 8 successively for first through hole 7 and the second through hole 8, and screw rod 2 of choosing connects the first locking nut 9 for location through the threaded one end of the second through hole 8; Taper bush 3 can move up and down formula and be nested with outside screw rod 2 of choosing, and taper bush 3 comprises the cone-shaped ejecting block 3-2 that bush body 3-1 and disjunctor are arranged on bush body 3-1 one end; Cone-shaped ejecting block 3-2 is equipped with in the second through hole 8, and the pin 5 that promotes when cone-shaped ejecting block 3-2 is mobile to tool body 1 inside to choose outwards ejects; The body of rod of taper bush 3 away from the screw rod 2 of choosing of cone-shaped ejecting block 3-2 one end is threaded the second locking nut 10 for location; Choosing, screw rod 2 one end away from tool body 1 is also provided with seat board 11 of choosing, and the choose screw rod 2 of seat board 11 away from the second locking nut 10 side is threaded the 3rd locking nut 12 for location choosing.
