Abstract
The utility model discloses a progressive type feed rod sealer which is composed of a rotating cover 1, a stuffing guiding groove 2, stuffing 3, a stuffing leading body 4, a pressing cover 5, a stuffing box 6, a center regulating body 7, etc., wherein the rotating cover is welded with the stuffing guiding body; the pressing cover is clamped in a groove of the rotating cover and the stuffing guiding body; both the pressing cover and the stuffing box are in screwed connection, and both the stuffing box and the center regulating body are in screwed connection; the structure which is formed by the process that an opening of the stuffing guiding groove is positioned at the side surface of the rotating cover presents in a spiral shape. The structure can reduce the desilting phenomenon or the effect of rain water on the stuffing guiding groove so as to enable the stuffing to be swimmingly filled in, and thus, the utility model prolongs the replacing period of the stuffing and reduces the operating times of maintenance.
Description
Technical field
The present invention relates to the polished rod sealer that a kind of oilfield uses, a kind of specifically laddering polished rod sealer that can continuous-feeding.
Background technology
At present, the polished rod seal equipment that China mouth of pumped oil well device uses mostly is packing box, and the filler of employing is annular packing, and the use of its filler is received a mandate very short, and when changing annular packing, oil pumper needs stop pumping, and changes trouble of operation; And adopt the polished rod sealer of continuous filler supply, its supply inlet to be subjected to the influence of sand setting or rainwater bigger at end face, and guiding groove is vertical shape, filler covers and has some setbacks.
Summary of the invention
The purpose of this utility model is to be subject at existing polished rod sealer the influence of sand setting or rainwater, filler covers shortcoming such as have some setbacks, the polished rod sealer of a kind of new packing supply of development and design structure, this structure can reduce the influence to the filler guiding groove of sand setting or rainwater, it is more smooth and easy that filler is covered, thereby prolong the replacement cycle of filler, reduce the upkeep operation number of times.
In order to achieve the above object, the laddering polished rod sealer of the utility model is made up of swivelling cover 1, filler guiding groove 2, filler 3, filler guide body 4, gland 5, stuffing box 6 and aligning body 7 etc.Described swivelling cover 1 and 4 welding of filler guide body; Gland 5 is stuck in the groove of swivelling cover 1 and filler guide body 4, and free to rotate, gland 5 is connected with stuffing box 6 by screw thread; Stuffing box 6 is threaded with aligning body 7.The opening of filler guiding groove 2 is positioned at the side of swivelling cover 1 on the described filler guide body 4, and structure is a spirality.
The utility model compared with prior art has the following advantages: the opening of filler guiding groove 2 is positioned at the side of swivelling cover 1, reduces the influence to the filler guiding groove of sand setting or rainwater; The structure design spirality of filler guiding groove 2, it is more smooth and easy that this covers filler.
Description of drawings
Below in conjunction with accompanying drawing the laddering polished rod sealer of the utility model is described in further detail.
Fig. 1 is the structural representation of the laddering polished rod sealer of the utility model.
Fig. 2 is the utility model filler guide body structure chart.
Fig. 3 is the expanded view of Fig. 2 filler guide structure.
Specific embodiment
As shown in Figure 1, the laddering polished rod sealer of the utility model is made up of swivelling cover 1, filler guiding groove 2, filler 3, filler guide body 4, gland 5, stuffing box 6 and aligning body 7 etc.
The integral body assembling and the use of the laddering polished rod sealer of the utility model are as follows: as shown in Figure 1, 2, 3, and described swivelling cover 1 and 4 welding of filler guide body; Gland 5 is stuck in the groove of swivelling cover 1 and filler guide body 4, and free to rotate, gland 5 is connected with stuffing box 6 by screw thread; Stuffing box 6 is threaded with aligning body 7.The opening of filler guiding groove 2 is positioned at the side of swivelling cover 1 on the described filler guide body 4, and filler guiding groove 2 structures are spirality.Filler 3 enters the packing cavity of stuffing box 6 from the spiral guiding groove 2 of the side that is positioned at swivelling cover 1.
In use, the utility model is installed on the mouth of pumped oil well device, oil pumping polish rod penetrates from the bottom of laddering polished rod sealer, and described sealer adopts tubing round thread to be connected with supporting well head.Bar shaped filler 3 is sent into from the spiral guiding groove 2 that is positioned at swivelling cover 1 side, utilized handle to rotate swivelling cover 1, filler progressively is involved in the packing cavity of stuffing box 6, oil pumping polish rod is held tightly, make it in the pumping of polished rod, play sealing function.
When pumpingh well was produced, top added the effect that the sealing polished rod can play in packing closure material mechanism.If oil well production after a period of time, when sealing effectiveness reduces, only needs slow rotary handle, encapsulant will be brought into annular seal space, and sealing effectiveness will strengthen greatly.
If polished rod and well head misalign, the aligning body 7 of this utility model bottom can be realized the automatic aligning sealing within the specific limits according to actual working state, avoids polished rod eccentric wear, scuffing.
If oil well need seal polished rod, only need the handle of rotation polished rod sealer, just the self-styled rubber in the aligning body 7 can be embraced polished rod, realize sealing.Thereby play the function of rubber gate.
