Abstract
The utility model relates to a following-up polish rod sealer used in an oil field pumping well, which comprises a vertical tower hole press hole 1, a rotating handle 2, tower type disk roots 3, 5, a tracing spring 4, an inverting tower hole seat 6, a high-pressure hose 7, and a fitting-in connector 8, wherein the bottom of the vertical tower hole press cap 1 is connected with the inverting tower hole seat 6 through screw, the bottom end of the tower seat 6 is connected with the fitting-in connector 8 through the high-pressure hose 7, one side of the top portion of the tower hole press cap 1 is provided with the rotating handle 2, the press cap 1 and the tower hole seat 6 are provided with the upper and the lower tower type disk roots 3 inside with the tracing spring 4 provided in the middle. The polish sealer has excellent bidirectional automatic following-up shrinkage sealing effect without manual frequent adjusting the disk root to press screw and improve sealing effect of the disk root, the inverting tower hole seat and the fitting-in connector are connected through the high-pressure hose making use of the flexibility of the hose, which realizes the automatic following-up concentricity of the polish rob and the disk root, which can completely eliminate lateral frication environment, fully realize the sealing performance of the disk root, and extend the service life.
Description
Technical field:
The utility model relates to a kind of well head production tree sealing device that oil field pumping well is produced that is used for.
Background technology:
In Process of Oil Pumping Unit Well, the polished rod that is pumping since stressed continuous variation, himself body is also along with change.Therefore, will form the angle of continuous variation between polished rod axis and the static wellhead sealing device packing axis fixed.Especially the reasons such as error of oil pumper basis and stress deformation of oil pumper own and oil pumper Installation and Debugging, the capital causes the axis of polished rod and the serious off-centre of central axis or the shape of sealer to have a certain degree, thereby packing caused serious eccentric wear, and, cause oil and gas leakage loss or contaminated environment with its quick damage.Like this, both increase cost of production and oil recovery worker's workload, wasted comprehensive resources again, also influenced ordinary production.For addressing this problem, the polished rod sealer of various structures such as eccentric type, bulb universal type polished rod sealer has been released at the scene, and has improved the eccentric wear degree of seal to a certain extent.But because they all are rigid structures, need artificial frequent the tracking to regulate, can only improve the degree of eccentric wear, but can't change even strengthen the angle of packing and polished rod axis, so fundamentally do not solve the eccentric wear problem.On encapsulating method, the sealing means that traditional sealer all adopts tower packing of single inversion and axial pressure radial centripetal to shrink basically, this encapsulating method is good sealing effect when the polished rod downstream state, but in the up process of polished rod the sealing effectiveness of packing is weakened relatively.If add the pressure-tight mode of side direction on this basis again, but when screwing set screw and increase pressure to packing, then can cause increasing counter productives such as frictional force, the wearing and tearing of aggravation packing, loss power.
The utility model content:
Thereby the purpose of this utility model can make black box such as sealed packing follow polished rod when being to provide a kind of work freely changes and makes the concentric Follow-up polished rod sealer that thoroughly solves the eccentric wear problem, improves the well head sealing effectiveness of polished rod axis and the servo-actuated of sealed packing axis.
The utility model is to realize like this.This kind polished rod sealer is made up of positive seting tower hole pressure cap, inverted setting tower hole seat, swing handle, cooperation joint, tower packing, high-pressure hose, tracking spring, positive seting tower hole pressure cap lower end is connected with the inverted setting tower hole seat with screw thread, and seat lower end, tower hole is connected with cooperating joint by high-pressure hose; Pressure cap top, tower hole one side is provided with swing handle, and upper and lower two inverted each other tower packings are housed in pressure cap and the tower hole seat, is provided with tracking spring therebetween.During work, the tower hole of two coaxial reverse symmetry settings can tracking spring and other axial force that tower type spiral rubber packing in it is suffered convert radial contraction power to, is used for the sealing to polished rod.Simultaneously, when polished rod is done axially reciprocating, utilize the frictional force between polished rod and the packing and the elastic force of spring,, also can obtain the effect of better two-way servo-actuated follow-up sealing even do not compressing artificially or compressing less under the situation of positive seting tower hole gland nut.
In addition, because inverted setting tower hole seat lower end is connected with the flexible high pressure flexible pipe of certain-length, the flexible pipe lower end is connected with the joint that cooperates with the production tree butt joint, utilize the flexibility of flexible pipe, the form that can make sealer top seal assembly is with polished rod form respective change, the automatic servo-actuated that realizes polished rod and packing is concentric, thereby reaches the not purpose of eccentric wear.
The utility model is reasonable in design, and is simple in structure, and cost is low, practical; The tower hole and the packing combining structure that adopt two coaxial reverse symmetry to be provided with, under the effect of the tracking spring between two packings, cooperate the reciprocating frictional force of polished rod, effect with good two-way automatic servo-actuated collapsed seal does not need the artificial frequent sealing effectiveness that the packing housing pin improves packing of regulating; Adopt high-pressure hose to be connected at the inverted setting tower hole seat between the joint with cooperating, utilize the flexibility of flexible pipe, realize that the automatic servo-actuated of polished rod and packing is concentric, can thoroughly eliminate the eccentric wear phenomenon, give full play to the sealing performance of packing, increase the service life.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.Wherein, label " 9 " is the pumpingh well polished rod.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is by positive seting tower hole pressure cap 1, swing handle 2, tower packing 3,5, tracking spring 4, inverted setting tower hole seat 6, high-pressure hose 7 and cooperate joint 8 to form, its assembling, annexation are as follows: positive seting tower hole pressure cap 1 lower end is connected with inverted setting tower hole seat 6 with screw thread, and seat 6 lower ends, tower hole are connected with cooperating joint 8 by high-pressure hose 7; Tower hole pressure cap 1 top one side is provided with swing handle 2, and upper and lower two tower packings 3,5 are housed in pressure cap 1 and the tower hole seat 6, is provided with tracking spring 4 therebetween.Wherein, positive seting tower hole pressure cap 1 is a pipe body, and the top periphery is provided with connection swing handle 2 and uses screw, and inner headed face is up-small and down-big, is just to put the turriform hole, and the bottom is provided with the internal thread that is connected usefulness with the inverted setting tower hole seat.Tower packing 3 and 5 is the turriform conveyor screw, is oppositely arranged up and down.Inverted setting tower hole seat 6 top peripheries match with pressure cap 1 and are provided with to be connected and use external screw thread, bottom that one round platform is arranged, and round platform one side bottom surface is provided with and connects the high-pressure hose circular hole, and inner headed face is up big and down small, are and are inverted the turriform hole.That high-pressure hose 7 can adopt is high temperature resistant, high pressure, acid and alkali-resistance, oil resistant and metal hose, bellows or high-pressure rubber pipe with certain flexibility.Cooperate joint 8 upper end round platform end face one sides to be provided with the high-pressure hose circular hole is set, the lower end is provided with to be connected with production tree uses oil tube external thread.
