Abstract

Provided is an automatic-discharging packing and automatic deviation regulating packing box. The automatic-discharging packing and automatic deviation regulating packing box mainly solves the problems that an existing packing box is difficult in packing replacement and complicated in structure. The automatic-discharging packing and automatic deviation regulating packing box is characterized in that the upper end of a lower connector (1) and the lower end of a deviation regulating cylinder (2) are provided with annular bosses respectively and connected through a lower pressing cap (3), the deviation regulating cylinder (2) can horizontally move by 360 degrees, a sealing ring is arranged on the upper end face of the lower connector (1), a nylon pad (6) is arranged between the upper end of the lower connector (1) and the lower end of the deviation regulating cylinder (2), a packing cylinder (4) is connected to the outside of the deviation regulating cylinder (2) through threads, a sealing ring is arranged outside the deviation regulating cylinder (2), a trapezoidal annular groove is formed in the upper end of the deviation regulating cylinder (2), an end face sealing ring (7) is arranged at the upper end of the deviation regulating cylinder (2), a sealing boss matched with the trapezoidal annular groove is arranged below the end face sealing ring, and packing is arranged in the packing cylinder (4) at the upper end of the end face sealing ring. The automatic-discharging packing and automatic deviation regulating packing box has the advantages of being convenient in packing replacement and simple in structure.

Description

Aytemesia packing automatic deflection adjusting packing box
Technical field:
The utility model relates to oil extraction in oil field field well head packing box used, especially aytemesia packing automatic deflection adjusting packing box.
Background technology:
In oil extraction in oil field field, packing box is installed on well head.And existing packing box is changed packing difficulty because reasons in structure exists, baroque problem, extends the repair time, increases maintenance cost, affects oil recovery efficiency.
Utility model content:
In order to solve existing packing box, change packing difficulty, baroque problem.The utility model provides a kind of aytemesia packing automatic deflection adjusting packing box.It is convenient that this aytemesia packing automatic deflection adjusting packing box has packing replacing, feature simple in structure.
The technical solution of the utility model is: this aytemesia packing automatic deflection adjusting packing box lower contact, tuningout cylinder, lower pressing cap, packing cylinder and upper pressing cap.There is respectively annular boss lower contact upper end and tuningout cylinder lower end, and be connected by lower pressing cap, tuningout cylinder can move horizontally by 360 degree, lower contact upper surface is equipped with sealing ring, between lower contact upper end and tuningout cylinder lower end, be equipped with nylon cushion, packing cylinder is threaded connection outside tuningout cylinder, tuningout cylinder has sealing ring outward, tuningout cylinder upper end has keystone ring connected in star, tuningout cylinder upper end is equipped with end-face seal ring, below end-face seal ring, there is the seal boss matching with keystone ring connected in star, end-face seal ring upper end packing cylinder is built-in with packing, packing upper end is equipped with gland, upper pressing cap is connected to packing cylinder upper end, packing cylinder and upper pressing cap are horizontally connected with tommy bar outward.
The utlity model has following beneficial effect: this aytemesia packing automatic deflection adjusting packing box is owing to adopting lower contact upper end and tuningout cylinder lower end to have respectively annular boss, and be connected by lower pressing cap, tuningout cylinder can move horizontally by 360 degree, lower contact upper surface is equipped with sealing ring, between lower contact upper end and tuningout cylinder lower end, be equipped with nylon cushion, packing cylinder is threaded connection outside tuningout cylinder, tuningout cylinder has sealing ring outward, tuningout cylinder upper end has keystone ring connected in star, tuningout cylinder upper end is equipped with end-face seal ring, below end-face seal ring, there is the seal boss matching with keystone ring connected in star, end-face seal ring upper end packing cylinder is built-in with packing, packing upper end is equipped with gland, upper pressing cap is connected to packing cylinder upper end, packing cylinder and upper pressing cap are horizontally connected with the structure of tommy bar outward.Utilize the rotation of packing cylinder by tuningout cylinder, packing to be ejected, thereby facilitate packing replacing, and simple in structure.This aytemesia packing automatic deflection adjusting packing box has packing replacing conveniently thus, feature simple in structure.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
1-lower contact in figure, 2-tuningout cylinder, 3-lower pressing cap, 4-packing cylinder, 5-upper pressing cap, 6-nylon cushion, 7-end-face seal ring, 8-gland.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this aytemesia packing automatic deflection adjusting packing box lower contact 1, tuningout cylinder 2, lower pressing cap 3, packing cylinder 4 and upper pressing cap 5.There is respectively annular boss lower contact 1 upper end and tuningout cylinder 2 lower ends, and be connected by lower pressing cap 3, tuningout cylinder 2 can 360 degree directions move horizontally, that is to say that tuningout cylinder 2 can move horizontally in lower contact 1 upper surface 360 degree directions, lower contact 1 upper surface is equipped with sealing ring, between lower contact 1 upper end and tuningout cylinder 2 lower ends, be equipped with nylon cushion 6, packing cylinder 4 is threaded connection outside tuningout cylinder 2, outside tuningout cylinder 2, there is sealing ring, tuningout cylinder 2 upper ends have keystone ring connected in star, tuningout cylinder 2 upper ends are equipped with end-face seal ring 7, below end-face seal ring, there is the seal boss matching with keystone ring connected in star, end-face seal ring upper end packing cylinder 4 is built-in with packing, packing upper end is equipped with gland 8, upper pressing cap 5 is connected to packing cylinder 4 upper ends, the outer tommy bar that is horizontally connected with of packing cylinder 4 and upper pressing cap 5.
During actual use, this aytemesia packing automatic deflection adjusting packing box is connected with well head by lower contact 1.While changing packing, unload upper pressing cap 5, rotation packing cylinder 4, packing cylinder 4 moves down, and tuningout cylinder 2 ejects the interior packing of packing cylinder 4, realizes and is convenient for changing packing object.During tuningout, unclamp lower pressing cap 3, polished rod drives tuningout cylinder 2 to move, and realizes the object of automatic deflection adjusting.
