Description
Technical field
The utility model relates to the blowout hookup that a kind of mechanical oil recovery is used, and particularly a kind of multi-functional blowout hookup belongs to the oil-extractor polish-rod sealing device.
Background technology
In oil field development, pumping production is the pith in the oil field development.Existing polish rod seal device mainly is made up of rubber gate and blowout prevention box, because of the rubber gate can not bear high pressure, when oil-field flooding takes effect, when pressure raises suddenly, often damage polluting.Anti-eccentric wear adopts horizontal sliding or spherical device, can not solve the eccentric wear problem that existing horizontal movement has angular deflection again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of three grades of high pressure tuningouts are provided, the horizontal tuningout of secondary, one-level angle tuningout, two-stage high pressure sealing, packing long service life, anti-pollution safe and reliable multi-functional blowout hookup.
The purpose of this utility model is to realize like this, by eccentric ball joint, locking is female, the eccentric ball valve joint, locating ring, packing, the packing cover, second piston, interior jump ring, valve piston, gland, centering ring, pressure cap is formed, its structural feature is, eccentric ball valve joint lower end is plugged in the eccentric ball joint, the two is connected and fixed by locking mother, the upper end of eccentric ball valve joint is embedded with secondary packing and second piston, the outside of the upper end of eccentric ball valve joint is provided with screw thread, assemble mutually with the internal thread of packing cover lower end, eccentric ball valve joint and packing inner room are equipped with locating ring.Be provided with interior jump ring between packing cover and second piston, embedding in the packing set upper side has valve piston, in the packing cover one-level packing is housed, and the packing gland that has centering ring is equipped with on one-level packing top, and pressure cap is arranged at the top of packing gland.
Described second piston, eccentric ball valve joint are equipped with joint ring.
Compared to existing technology, of the present utility modelly be provided with the combination of three grades of tuningouts and the two-stage high pressure sealing is made up, make it realize comprehensive level, angle tuningout, bearing capacity increases greatly, good sealing effect, and the synergy of packing long service life is obvious.
The explanation of accompanying drawing drawing
Fig. 1 is a sectional drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 in detail the utility model is described in detail.
The utility model is the improvement of utility model patent " multi-functional blowout hookup " to my invention.Improved position is, change off-centre hoop head into the eccentric ball valve joint, concrete structure such as Fig. 1, the utility model is made up of eccentric ball joint 1, locking mother 2, eccentric ball valve joint 3, locating ring 4, packing cover 5, two utmost point packings 6, second piston 7, interior jump ring 8, valve piston 9, one-level packing 10, gland 11, centering ring 12, pressure cap 13.Form three grades of high pressure tuningouts by eccentric ball joint 1, locking mother 2, eccentric ball valve joint 3, form the two-stage high pressure sealing by packing cover 5, two utmost point packings 6, second piston 7, interior jump ring 8, valve piston 9, one-level packing 10, gland 11, centering ring 12, pressure cap 13.Can comprehensive level, eccentric ball valve joint 3 lower ends of angle tuningout are plugged in the eccentric ball joint 1, and the two is connected and fixed by locking female 2, upper end at eccentric ball valve joint 3 embeds secondary packing 6 and second piston 7, outside in eccentric ball valve joint 3 upper ends is provided with screw thread, the internal thread that overlaps 5 lower ends with packing assembles mutually, at eccentric ball valve joint 3 and 5 in packing cover locating ring 4 is housed simultaneously, controls the degree of tightness of secondary packing 6. Packing cover 5 and 7 of second pistons are provided with interior jump ring 8 and fix second piston 7 and prevent that it from coming off.Overlap 5 upper ends at packing and embed valve piston 9, in the packing cover 5 one-level packing 10 is housed, the packing gland 11 that has lubricated box and embed the centering ring 12 that is used to prevent the polished rod vibration is equipped with on one-level packing 10 tops, and packing pressure cap 13 is arranged at the top of packing gland 11.On second piston 7 and eccentric ball valve joint 3, be equipped with joint ring 14.
During concrete enforcement, this device is penetrated oil-extractor polish-rod, and it is seated on the well head.Fitting operation: unclamp locking nut 2, come rotating eccentricity ball joint 1 to make oil-extractor polish-rod and eccentric ball joint 1 endoporus centering according to the oil-extractor polish-rod eccentric position as far as possible, eccentric ball joint 1 is connected with well head, rotating eccentricity ball valve joint 3, entirely on the center up to oil-extractor polish-rod and multi-functional blowout prevention box, locking locking nut 2, load onto one-level packing 10, build packing gland 11, tightly go up packing pressure cap 13, compress one-level packing 10, start oil pumper.The replacing of multi-functional blowout hookup one-level packing: stop oil pumper work, take off locating ring 4, the packing that turns clockwise cover 5 compresses secondary packing 6 up to second piston 7, take out packing gland 11 and one-level packing 10, add one-level packing 10, build packing gland 11 tight good packing pressure caps 13, be rotated counterclockwise packing cover 5, unclamp secondary packing 6, load onto locating ring 4, start oil pumper.
