Abstract
The utility model discloses a polished rod sealing device, which belongs to an auxiliary technology for an oil extraction wellhead of an oil field and overcomes the defects existing in the prior art. The polished rod sealing device is formed by connecting a sealing device body, a bottom grand, a sealing packing, a lubricating cabin, a grease nipple, a lubricating core, an auxiliary packing, a top grand and a pressing cap, wherein the sealing device body is arranged at the bottom of the polished rod; the grand is arranged on the bottom polished rod of the sealing device body; the sealing packing is sleeved on the outer side of the gland; the lubricating cabin is sleeved on the sealing device body; the lubricating core is arranged in the lubricating cabin and is provided with the grease nipple through the lubricating cabin; the upper part of the polished rod is provided with the pressing cap; the top grand is sleeved on the polished rod in the pressing cap; and the auxiliary packing is sleeved on the outer side of the middle part of the top grand.
Description
Technical field: the utility model relates to the ancillary technique of oil well mouth, especially a kind of polished rod sealer.
Background technology: all be to rely on polished rod sealer that wellhead polish rod is sealed in the oil production technology of oil field.The widely used polished rod sealer in oil field all is to use metal Glan and pressure cap both at home and abroad at present, and is bigger to the wearing and tearing of polished rod; For the greasy property difference serious wear that goes out well and high water-cut well packing, cause packing to lose efficacy.
Summary of the invention: the purpose of this utility model provides a kind of polished rod wearing and tearing that alleviate, prolong packing a kind of polished rod sealer in application life, it has overcome states the defective that prior art exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by sealer body, bottom Glan, sealed packing, lubricated cabin, grease nipple, lubricating wick, auxiliary packing, top Glan, pressure cap, in the bottom of polished rod the sealer body is installed, polished rod is installed with Glan in the bottom of sealer body, is overlapping sealed packing in the outside of Glan; Overlapping lubricated cabin in the top of sealer body, in the lubricated cabin lubricating wick is being arranged, on lubricating wick, by lubricated cabin grease nipple is being installed; Top at polished rod is installed with pressure cap, and the polished rod in pressure cap is overlapping the top Glan, and auxiliary packing is being overlapped in the outside at top Glan middle part.
During use, because the fit clearance of bottom Glan and sealer body and polished rod is reduced, play the effect that polished rod is set upright in the bottom, simultaneously since material wear and tear and reduce than the soft light bar Shi Yuqi that moves up and down; The top Glan except anti-attrition is set upright at the top, the pressure cap that turns clockwise during tight packing, the auxiliary packing of top Glan compression, lubricating wick, sealed packing are realized the sealing of polished rod; Lubricating wick is loaded in the lubricated cabin, and lubricant grease injects in the lubricated cabin by grease nipple and is stored in the cabin internal pore, enters the packing gap under the elastic force effect of packing distortion packing and polished rod are lubricated; Thereby overcome the defective that present polished rod sealer wearing and tearing polished rod and packing can't lubricate, thereby reduce the polished rod wearing and tearing and prolong packing application life.
Description of drawings: Fig. 1 is a kind of structural representation of polished rod sealer, among the figure 1, sealer body 2, bottom Glan 3, sealed packing 4, lubricated cabin 5, grease nipple 6, lubricating wick 7, auxiliary packing 8, top Glan 9, pressure cap
The specific embodiment: embodiment 1, the utility model are to be formed by connecting by sealer body 1, bottom Glan 2, sealed packing 3, lubricated cabin 4, grease nipple 5, lubricating wick 6, auxiliary packing 7, top Glan 8, pressure cap 9, in the bottom of polished rod sealer body 1 is installed, polished rod is installed with Glan 2 in the bottom of sealer body 1, is overlapping sealed packing 3 in the outside of Glan 2.
