Abstract
The utility model discloses a lubrication type packing box which comprises a pressing cap, a packing box body and a grease plugging chamber. The lubrication type packing box is characterized in that the packing box body is tubular, wherein a thread-connected pressing cap is arranged at the upper part of the packing box body; a gland is arranged between the pressing cap and the packing box body; a cylindrical grease plugging chamber, which has the diameter greater than that of the packing box, is arranged on the lower middle part of the packing box body; a cylindrical rubber concave body with an outward opening is arranged in the grease plugging chamber; a grease nipple is arranged on the periphery of the grease plugging chamber; male threads are formed at the lower end of the grease plugging chamber; and a cylindrical packing is arranged between the gland in the packing box body and the cylindrical rubber concave body. According to the lubrication type packing box, the packing presses the cylindrical rubber concave body by a downward carrying force for the packing when a polished rod descends so as to extrude the grease and adhere the grease onto the polished rod, so that the lubricity and the tightness of the polished rod and the packing are enhanced, the service life of the packing is prolonged, the grease leakage probability and the packing replacement times are reduced, and the work intensity of oil workers is reduced.
Description
Technical field
The utility model relates to a kind of oil pumping machine well head seal member, specifically a kind of lubricated type packing box.
Background technology
The oil field is in high water-cut stage at present, and oil production method is mainly mechanical oil recovery, due to moisture height, packing in wellhead packing box is often ground away by polished rod, cause poorly sealedly, physical life is short, often changes packing, profit leaks into well head and causes pollution to wellhead equipment and surrounding environment in addition, for reaching the requirement of carrying out production strictly in line with rules and regulations, the oil recovery workman must often clear up, and gives that the oil recovery workman is meaningless has increased great work load, bustling about every day is for this reason carried out precision management to oil well without the time.
Summary of the invention
The purpose of this utility model is to provide a kind of lubricated type packing box, overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises that pressure cap, packing box body and butter block up oil pocket, it is characterized in that the packing box body is made as tubular, top is provided with the pressure cap that is threaded, be provided with gland between pressure cap and packing box body, be provided with at lower middle part greater than the stifled oil pocket of the cylindrical butter of packing box diameter, be provided with a mouthful outside cylindrical rubber concave body in the stifled oil pocket of butter, be provided with a grease nipple in the stifled oil pocket periphery of butter, be provided with male thread in the bottom, establish cylindrical packing between the gland in the packing box body and cylindrical rubber concave body.
The internal diameter of cylindrical rubber concave body is identical with the external diameter of polished rod, and the internal diameter of the stifled oil pocket of external diameter and butter is identical, evenly is provided with intercommunicating pore at the bottom portion of groove of cylindrical rubber concave body.
The utility model is by the descending power of carrying downwards to packing of polished rod, packing presses the cylindrical rubber concave body that butter is extruded, viscous is on polished rod, strengthen polished rod and packing lubricity and sealing, thereby extended the application life of packing, reduce the probability of profit leakage and the number of times of replacing packing, reduced oil recovery workman working strength.
Description of drawings
Accompanying drawing-structural representation of the present utility model;
1-pressure cap in figure, the 2-gland, 3-packing box body, the 4-packing, the 5-butter blocks up oil pocket, 6-grease nipple, 7-cylindrical rubber concave body.
The specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises that pressure cap 1, packing box body 3 and butter block up oil pocket 5, it is characterized in that packing box body 3 is made as tubular, top is provided with the pressure cap 1 that is threaded, be provided with gland 2 between pressure cap 1 and packing box body 3, be provided with at lower middle part greater than the stifled oil pocket 5 of the cylindrical butter of packing box diameter, be provided with a mouthful outside cylindrical rubber concave body 7 in the stifled oil pocket 5 of butter, be provided with a grease nipple 6 in stifled oil pocket 5 peripheries of butter, be provided with male thread in the bottom, establish cylindrical packing 4 between the gland 2 in packing box body 3 and cylindrical rubber concave body 7.
When using the utility model, it is arranged on wellhead tee joint, block up oil pocket 5 interior filling butter by grease nipple 6 toward butter with grease gun at any time in the oil well production process, butter is high temperature resistant butter preferably, must fill it up with butter, cylindrical rubber concave body 7 is heaved, in service a small amount of the extruding of butter with polished rod, viscous strengthens lubricity and the sealing of polished rod and packing 4 on polished rod, do not make the dry grinding of polished rod and packing, extended the application life of packing.
