Abstract
The utility model relates to a novel multi function packing set box of oil extraction well, which relates to an oil extraction well leakage proof, theft proof and rod wear proof sealing part and auto compensating sealing device after the sealing part is worn out. The utility model comprises a fluid cylinder, an upper and lower joint, an upper and lower oil sealing, an upper pressing cover, a piston, a connecting tank sleeve, a safe sleeve plate, a locating socket, a complex packing set, a centrifugal shaft, a pulley and a centrifugal connecting plate. When in use, the centrifugal connecting plate is thread jointed with the oil well faucet and the rod passes through the central hole of the utility model and is adjustable. The complex packing set and the rod are sealing connected. The piston and spring are of auto compensating and sealing function. When the rod is worn out or damaged, the steel ball covers the position and seals. The utility model is good in sealing performance, theft and leakage proof and convenient in installation, operating, replacing and maintenance, which can prevent well blowout caused by the rod being worn out or damaged. The sealing part is auto compensated after being worn out, which is capable of changing parts continuously.
Description
Technical field
The utility model relate to a kind of mouth of pumped oil well anti-leak, antitheft, prevent behind polished rod wearing and tearing seal and the sealing part abrasion sealing device of compensation automatically.
Background technology
For preventing that the oil in the pumpingh well from leaking, and needs a kind of well mouth sealing device of design.The previous rubber gate valve that adopts, after design multiple packing box again, as " pumpingh well wellhead polish rod adjust sealing ring " (patent No. 99219571) etc., it is by pressure cap, packing box, packing, ball core body, spheroid, flange, positioning bolt, fastening bolt, special-purpose promote and upper and lower spherical cap is formed I and II sealing, horizontal tuningout, angle tuningout, well head blowout prevention, 6 parts of antitheft flange.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of good airproof performance, antitheft, the anti-leak of energy, can prevent that polished rod from use causing blowout because of fatigue break, can compensate automatically behind the sealing part abrasion, polished rod be had the mouth of pumped oil well Multifunction packing box of tuningout, centralizing function.
The implementation of the utility model purpose is that mouth of pumped oil well Multifunction packing box includes packing, terminal pad.Top connection 25 is arranged on the hydraulic cylinder 1, go up oil sealing 26, upper press cover 27, the cylinder sleeve 2 of connection, lower contact 3, condom dish 4, following oil sealing 5, positioning sleeve 6 are arranged down.Condom dish one side has steel ball 13, and steel ball 13 is by silently 14 sealing.Positioning sleeve 6 is connected with eccentric terminal pad 8, and there is rubber gasket 7 junction.Eccentric shaft 10, pulley 9, support 28 are connected as a single entity with eccentric terminal pad 8.There is plug 17 on the hydraulic cylinder both sides, and the plug external surface is the inclined-plane.Special-shaped packing 15, O type rubber ring 16 are housed in the hydraulic cylinder.Piston 23 is connected as a single entity with special-shaped packing 15, trip bolt 22, spring 21, spring capping 20, adjustment screw 18.
Eccentric terminal pad 8, down oil sealing 5, condom dish 4, special-shaped packing 15, the through hole that passes polished rod is arranged in the middle of going up oil sealing 26, upper cover 27.
The utility model is made of hydraulic cylinder 1, upper and lower joint 25,3, condom dish 4, positioning sleeve 6, eccentric terminal pad 8 etc.During use, eccentric terminal pad is threaded with well mouth of oil well, and the polished rod in the oil well passes the through hole at the utility model center, and 15 of polished rod and special-shaped packings are tightly connected.
Long when service time, the contact surface of special-shaped packing 15 is worn and influences when sealing, and piston 23 can inwardly promote special-shaped packing, and the tension force of spring 21 withstands it, and contact surface is resealed, so have from mending sealing function.
Polished rod causes gas blowout accident because of the fatigue break meeting in long-term use, the utility model is equipped with steel ball 13 in condom dish 4 one sides, in case polished rod fractures, powerful oil pressure, air pressure can be pushed into steel ball 13 in the centre bore heart hole of cylinder sleeve 2, through hole is blocked from here, also be about to mouth of pumped oil well and seal, so the utility model is safe and reliable.
In the eccentric terminal pad 8 support 28, eccentric shaft 10, pulley 9 are housed, eccentric shaft is rectified a deviation to the off normal that polished rod may occur, and pulley is set upright askew polished rod, makes polished rod be in the center of through hole all the time, reduces the wearing and tearing of polished rod to special-shaped packing 15.
There is plug 17 on hydraulic cylinder 1 both sides, and the plug external surface is the inclined-plane, must it could be unloaded with special tool, so the utility model has the function that prevents that crude oil is stolen.
According to the requirement of the strata pressure of oil well yield and oil well mouth, the utility model can be mounted to two, three layers, when upper two layers is installed, need not load the part of setting upright of face.When special-shaped packing 15 seals such as grade of undermost packing box need be changed, other packing box can work on, so the utility model can change part, maintenance work under non-stop-machine situation.
The utility model good seal performance, part, easy to maintenance is installed, operates, changed to antitheft, the anti-leak of energy, can prevent that polished rod from use because of fatigue break causes blowout, can compensate behind the sealing part abrasion automatically, can not shut down and change part, maintenance.

The specific embodiment
The utility model is made of hydraulic cylinder 1, upper and lower joint 25,3, condom dish 4, positioning sleeve 6, eccentric terminal pad 8 etc.Abnormity packing 15, O type rubber ring 16 implement to compensate automatically and regrind compensating unit again behind the formation sealing part abrasions such as piston 23, trip bolt 22, spring 21, spring capping 20.Condom dish 4, steel ball 13, silently 14, cylinder sleeve 2 constitutes anti-polished rod wearing and tearing and fractures, mends the member of stifled sealing.Eccentric terminal pad 8, support 28, pulley 9, eccentric shaft 10 constitute the polished rod correction and set upright parts.Abnormity packing 15 is a comb shape with the polished rod contact surface, and the comb shape between cog thing that can reject, comb shape can reduce large-area hard contact the between special-shaped packing and polished rod, make contact surface flexible, and rigid wearing and tearing are few, increase the service life.
