Abstract
The utility model discloses a multifunctional automatic slick bar adjusting sealer, containing a sealing device and an automatic adjusting device; wherein the sealing device consists of a packing set, a pressure loop, a packing set nut and a handle; and the automatic adjusting device consists of an adjusting ball, an adjusting nut, an upright sleeve, an O shape ring and a main body. The utility model is an improvement to the prior sealing instrumentation, which integrated the adjusting ball, the adjusting nut, the upright sleeve and the O shape ring into one entity; the inner surface at the upper of the main body is designed into a sphericity, the center of the main body is a cone shape and the lower of the main body is a tube shape; the combination component of the center and the middle of the main body and the combination of the middle and the lower of the main body are both moveable matched the slick bar; the center of the cone shape has a sealing floating ball; and the lower of the main body is provided with a well seal rubber valve. The improved sealer can solve the problems that the gasket is worn by one part and oil base leakage caused by the excursion of the axis of the slick bar and the sealing main body; and the utility model can automatic adjust excursion, close a well when the slick bar shield and facilitating exchanging packing set.
Description
One, technical field
The utility model relates to the rod-pumped well jaws equipment, specifically is multi-functional automatic deflection adjusting polished rod sealer.
Two, background technology
Polished rod sealer is the vitals of rod-pumped well jaws equipment, the problem that employed polished rod sealer existed during recovered the oil in the oil field at present is: can not adapt in the oil pumper running because the well head offset problem that polished rod axis that influence of various factors such as oil pumper manufacturing alignment error and pit shaft inclination produce and the skew of sealer main body axis cause causes sealing ring eccentric wear, crude oil leakage; The sealer function singleness, automatic closing well behind the bar that can not break in case blowout will take place in the polished rod down-hole that falls of the breaking during no one, causes serious economy loss.In addition, also exist dismounting and adjust numerous and diverse, the difficult problem of packing.
Three, summary of the invention
The purpose of this utility model provides a kind of multi-functional automatic deflection adjusting polished rod sealer, is improved with polished rod sealer former, makes the polished rod sealer after the improvement can automatic deflection adjusting, closing well automatically when polished rod comes off.
The utility model is to realize so by the following technical programs: multi-functional automatic deflection adjusting polished rod sealer comprises sealing device, automatically deviation-adjusting device, and sealing device wherein is made up of packing, pressure ring, packing pressure cap, handgrip; Automatically deviation-adjusting device is by adjusting ball, adjustment pressure cap, supporting positive cover, " O " type circle, main body formation; In automatically deviation-adjusting device, will adjust ball and adjust pressure cap, supporting positive cover, " O " type circle composition one, the main body upper inside surface is designed to sphere, the middle part is taper, the bottom is a tubular, the binding site of the binding site at its top and middle part and middle part and bottom all with polished rod movingly, tapered middle is equipped with sealed ball float; Shut-in well rubber valve is installed in the bottom of main body, and shut-in well rubber valve is threaded with lower body part.
The good effect that the utlity model has:
1, have well head automatic deflection adjusting function: adjustment ball in its automatically deviation-adjusting device and supporting positive cover adjust pressure cap and " O " type circle is formed one, can seal, can reach the purpose of adjusting well head off-centre by the rotation of adjusting ball again, can solve because the problem of the sealing ring eccentric wear that the skew of polished rod axis and sealed body axis causes, leakage crude oil.
2, have automatic closing well function: break when falling the down-hole at polished rod, the ball float of installing in the main body can be under the fluid pressure effect, and come-up with the well head sealing, is avoided blowout automatically.
3, be convenient for changing packing: the utility model after the improvement is equipped with a cover shut-in well rubber valve in lower body part, in case need change portion's packing the time, the spool of symmetry can be screwed and block polished rod, changes packing easily.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 packing, 2 pressure rings, 3 packing pressure caps, 4 handgrips 5 are adjusted ball 6 and are adjusted pressure cap 7 supporting positive cover 8 " O " type circles 9 seal receptacles 10 main bodys 11 sealed ball floats 12 shut-in well rubber valves
Five, the specific embodiment
Figure 1 shows that the utility model structural representation, as shown in the figure, multi-functional automatic deflection adjusting polished rod sealer comprises sealing device, automatically deviation-adjusting device, and sealing device wherein is made up of packing 1, pressure ring 2, packing pressure cap 3, handgrip 4, and handgrip 4 is fixedly mounted on outside the packing pressure cap 3.Adjustment ball in the automatically deviation-adjusting device 5 and adjustment pressure cap 6, supporting positive cover 7, " O " type circle 8 are formed one, main body 10 upper inside surface are designed to sphere, the middle part is taper, the bottom is a tubular, the binding site of the top of main body 10 and the binding site at middle part and middle part and bottom all with polished rod movingly, tapered middle is installed sealed ball float 11.The ball neck of adjusting ball 5 is threaded with the packing pressure cap 3 of sealing device, packing 1 is filled in the ball neck and the annular space between the polished rod of adjusting ball 5, adjust the spheroid outer wall of ball 5 " O " type circle 8 is installed, place in the top diameter of Spherical Volume of automatic closing well device main body 10, overcoat is adjusted pressure cap 6, supporting positive cover 7 is enclosed within outside the polished rod, and in the spheroid top and the annular space between the polished rod of adjusting ball 5, there is seal receptacle 9 lower end of adjusting the spheroid of ball 5.The rotation that is reliable spheroid like this reaches the purpose of adjusting well head off-centre, can play the effect of sealing again.Shut-in well rubber valve 12 is threaded with the cylindrical lower of main body 10, symmetry be installed on main body 10 below.Polished rod passes sealing device, automatically deviation-adjusting device, shut-in well rubber valve 12 from top to bottom successively.When polished rod breaks when falling the down-hole, sealed ball float 11 is under the pressure effect of liquid, and come-up reaches the purpose of closing well to adjusting ball 5 times automatically.Shut-in well rubber valve 12 is threaded with the cylindrical lower of main body 10, symmetry be installed on main body 10 below.In case in the time of need changing portion's packing 1, the rubber spool of symmetry can be screwed and block polished rod, can change packing 1 this moment easily.
