Abstract
The utility model belongs to a lubrication type double-sealing packing box used for a mouth of an oil well, and particularly relates to a lubrication type double-sealing packing box, which can prevent a sucker rod from wearing the sealing packing when moving upward and downward in production of the oil well. The lubrication type double-sealing packing box consists of the sucker rod, a sealing base, a steel drum, a lower sealing sleeve, an oil nipple, an oil bearing sleeve, an upper sealing sleeve, a press cushion and a press cover. The lubrication type double-sealing packing box is characterized in that the steel cylinder is mounted at the upper outer end of the sealing base; the oil nipple is mounted outside the steel cylinder; the lower sealing sleeve, the oil bearing sleeve, the upper sealing sleeve and the press cushion are sequentially mounted inside the steel drum; and the upper end of the steel cylinder is connected with the lower end of the press cover. The lubrication type double-sealing packing box provided by the utility model has the beneficial effects of simple structure and easiness of operation, can achieve the effect of lubricating the sucker rod and preventing the sealing sleeve from being worn, and is safe and reliable.
Description
Technical field
The utility model belongs to well mouth of oil well lubricated type double containment packing box, and sucker rod moves up and down a kind of lubricated type double containment packing box of wearing and tearing sealed packing in the time of especially preventing oil well production.
Background technology
At present, each elephant of China all is common well head sealing packing box to the employing of producing well well head sealing packing box, and this common well head sealing packing box does not reach antiwear effect when producing, cause the well head sealing packing serious wear.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of lubricated type double containment packing box, this lubricated type double containment packing box, the outer end is equipped with steel cylinder on the seal receptacle, the steel cylinder outside is equipped with fuel filler neck, cylinder barrel inside is equipped with lower sleeve gasket in order, contain oil jacket, upper sleeve gasket, pressure pad, the upper end of steel cylinder is connected with the lower end of gland, the pressure pad that is glanded compression is descending, make, lower sleeve gasket expands, and this moment, sucker rod and steel cylinder sealed, and lubrication oil is joined from fuel filler neck contain in the oil jacket, sucker rod moves up and down during oil well production, lubrication oil plays the effect of lubricated sucker rod, makes upper sleeve gasket and lower sleeve gasket lubricated, prevents, the lower sleeve gasket wearing and tearing.
The technical scheme in the invention for solving the technical problem is: a kind of lubricated type double containment packing box by sucker rod, seal receptacle, steel cylinder, lower sleeve gasket, fuel filler neck, contain oil jacket, upper sleeve gasket, pressure pad, gland and form, its special character is: the outer end is equipped with steel cylinder on the seal receptacle, the steel cylinder outside is equipped with fuel filler neck, cylinder barrel inside is equipped with in order lower sleeve gasket, contains oil jacket, upper sleeve gasket, pressure pad, and the upper end of steel cylinder is connected with the lower end of gland.
