Abstract
The utility model relates to a blowout prevention box of a wearable packing, which mainly solves the problem that the packing wear is fastened because the existing blowout prevention box is not provided with a lubricating device of a packing and a polish rod. The utility model is characterized in that a packing (2) is arranged in a shell (1); a press cover (3) for pressing the packing (2) is connected to the upper end of the shell (1) through a thread; an oil storing chamber (4) is arranged in the press cover (3); foams (5) are filled with the lower part in the oil storing chamber (4); lubricating oil is filled in the oil storing chamber (4); an oiling one-way valve (6) is arranged at the upper end of the press cover (3); and oil leaking holes (7) are arranged at the bottom of the press cover (3). The utility model has the advantages of that the packing wearing speed is reduced, the packing use life is prolonged, and the like.
Description
Technical field:
The utility model relates to the used blowout prevention box of oil recovery field, oil field oil pumper well head, especially wear-resisting packing blowout prevention box.
Background technology:
Along with Oilfield developing, environmental protection is more and more important.In order to improve environment protecting, the blowout prevention box is installed all on the oil pumper well head.And present existing blowout prevention box is accelerated the packing rate of wear owing to do not have packing and a polished rod lubricating arrangement, shortens packing application life, and packing is frequently changed, and then the prolongation stop pumping time, has influenced the recovery ratio of oil well.
The utility model content:
In order to solve the problem that existing blowout prevention box does not have packing and the wearing and tearing of polished rod lubricating arrangement packing to accelerate, the utility model provides a kind of wear-resisting packing blowout prevention box, and this wear-resisting packing blowout prevention box has the packing of the reduction rate of wear, prolongation packing application life etc. characteristics.
The technical solution of the utility model is: this wear-resisting packing blowout prevention box comprises housing, housing is built-in with packing, the housing upper end compresses the gland of packing by being threaded, shoe cream room is arranged in the gland, the interior under-filled foam that has of shoe cream room, be filled with lubrication oil in the shoe cream room, there is the oiling one way valve gland upper end, oil seepage hole is arranged at the bottom of the gland.
The utlity model has following beneficial effect: this wear-resisting packing blowout prevention box is because employing is filled with lubrication oil and foam in the gland shoe cream room, optimizing structure of oil seepage hole arranged at the bottom of the gland, it is lubricated to utilize foam and oil seepage hole to form packing, packing wearing and tearing are slowed down, thereby strengthened sealing effectiveness, prolong packing application life, reducing packing changes, and then shorten the stop pumping time, and guaranteed the recovery ratio of oil well, and simple in structure.This wear-resisting packing blowout prevention box has and reduces the packing rate of wear thus, prolong packing application life etc. characteristics.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-housing among the figure, 2-packing, 3-gland, 4-shoe cream room, 5-foam, 6-refuel one way valve, the 7-oil seepage hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this wear-resisting packing blowout prevention box comprises housing 1, housing 1 is built-in with packing 2, housing 1 upper end compresses the gland 3 of packing 2 by being threaded, shoe cream room 4 is arranged in the gland 3, the shoe cream room 4 interior under-filled foams 5 that have, by foam 5 control lubrication oil oil impregnate amounts, be filled with lubrication oil in the shoe cream room 4, there is the one way valve 6 of oiling gland 3 upper ends, and gland has oil seepage hole 7 at 3 the end.
During actual the use, should be connected on the well head wax removal valve by wear-resisting packing blowout prevention box, polished rod passes gland 3 and packing 2, gland 3 is threaded with housing 1, the one way valve 6 that refuels again injects lubrication oil in gland 3 shoe cream rooms 4, regulate the compaction degree of packing 4 by gland 3, can normally use.When the polished rod up-downgoing, the lubrication oil in gland 3 shoe cream rooms 4 is seeped into packing 2 through foam 5 and oil seepage hole 7, by foam 5 control lubrication oil oil impregnate amounts, rubs between oil lubrication packing 2 and the polished rod.
In sum, this wear-resisting packing blowout prevention box sealing effectiveness improves, and reduces packing 4 wearing and tearing, and prolong the application life of packing, and packing is changed number of times and reduced, and reduces the rod-pumped well stop pumping time, reduces cost for oil production, increases the oil recovery benefit, and simple in structure.
