Abstract

The utility model relates to a multifunctional stuffing box which mainly solves the problems that a pumping well stuffing device in the prior art is poor in lubrication effects, not blowout preventive and prone to damage for a stuffing box pressing cover. The multifunctional stuffing box is characterized in that the upper portion of a lower ball seat (1) is matched with a ball joint (5) through the ball face, a butter seat (3) and an upper stuffing glue cushion (2) are arranged inside the lower ball seat (1), a butter mouth (4) is connected on the side wall of the lower ball seat (1), a sealing ring (8) is arranged between the ball joint (5) and the lower ball seat (1), and a pressing cap (7) is connected outside the lower ball seat (1) in a threaded mode. A plurality of groups of upper stuffing glue cushions (16) are arranged inside the ball joint (5), a stuffing pressing cap (13) is arranged on the upper portion of the upper stuffing glue cushions (16), and connecting nuts (12) are connected above the ball joint (5) through threads, an a stuffing pressing cap (14) is connected outside the connecting nuts (12). The multifunctional stuffing box has the advantages of being good in lubrication effects, good in blowout preventive performances, and not prone to damage.

Description

Multifunction packing box
Technical field
The utility model relates to the aboveground device of a kind of oil pumping in oil fields, specifically a kind of Multifunction packing box.
Background technology
Packing box is requisite device on the rod-pumped well.The packing box of most makes between packing and the polished rod frictional resistance large because lubricant effect is poor, and add incessantly at the pumping phase packing, packing box emits water; When dismantling gland for packing box, the liquid in the well waste and old packing and pressure cap often occur and squeezes in gland for packing box from packing box hydrojet outward, and when stingy pressure cap and old packing operated, the gland for packing box internal thread was fragile, brings difficulty to production management.
Summary of the invention
Existing rod-pumped well packing box lubricant effect is poor in order to overcome, not blowout prevention, the flimsy deficiency of gland for packing box, the utility model provides a kind of Multifunction packing box, and this Multifunction packing box has high lubricating effect, good, the non-damageable characteristics of blowout prevention performance.
The technical solution of the utility model is: a kind of Multifunction packing box, comprise lower ball base, described lower ball base top cooperates by sphere with spherojoint, lower ball base inside is equipped with butter seat and upper packing rubber cushion, be connected with the grease nipple that communicates with the butter seat on the lower ball base sidewall, be provided with joint ring between spherojoint and the lower ball base, described lower ball base external screw-thread connects pressure cap; Described spherojoint inside is provided with packing rubber cushion on some groups, and upper packing rubber cushion top is provided with packing pressure cap, and spherojoint top is connected with the attaching nut by screw thread, and the attaching nut is externally connected to packing gland.
Be provided with dividing plate between the described upper packing rubber cushion.Described butter seat top is provided with the pressure-conducting disk root plug.
The utlity model has following beneficial effect: owing to take such scheme, be connected with grease nipple on the lower ball base sidewall, can be to its inner butter of annotating by grease nipple, butter enters between polished rod and the packing by the butter seat, improve the polished rod lubricant effect, energy-conservation, improve system effectiveness, and save the packing expense and alleviate the degree of wear of polished rod; There are packing rubber cushion, butter seat in lower ball base inside, can play sealing function, and because the pressuring action of pressure-conducting disk root plug, when dismantling gland for packing box, the packing in the lower ball base keeps sealing state with polished rod all the time, so can oil spout; This packing box is when getting old packing operation simultaneously, and the gland for packing box internal thread can not damage, thereby alleviates employee's labour intensity, has avoided waste, has improved managerial skills.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-lower ball base among the figure, packing rubber cushion under the 2-, 3-butter seat, 4-grease nipple, 5-pressure-conducting disk root plug, 6-spherojoint, the 7-pressure cap, 8-joint ring, 9-dividing plate, bull stick under the 10-, the upper bull stick of 11-, 12-attaching nut, 13-packing pressure cap, 14-gland for packing box, 15-sucker rod, the upper packing rubber cushion of 16-.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of Multifunction packing box, comprise lower ball base 1, sucker rod 15 places in the lower ball base 1, and described lower ball base 1 upper inner and spherojoint 5 cooperate by sphere, and lower ball base 1 inside is equipped with butter seat 3, butter seat 3 inner hollow, be connected with the grease nipple 4 that communicates with butter seat 3 on lower ball base 1 sidewall, can by grease nipple 4 to butter seat 3 interior notes butter, play lubricated effect to polished rod.Lower ball base 1 inside, butter seat 3 bottoms also are provided with lower packing rubber cushion 2, butter seat 3 tops are provided with packing plug 5, can compress lower packing rubber cushion 2 by compression plate rhizoid stifled 5, thereby realize sealing, and when dismantling gland for packing box, the packing of lower ball base 1 bottom keeps sealing state with polished rod all the time, so can oil spout, be provided with joint ring 8 between spherojoint 5 and the lower ball base 1, described lower ball base 1 external screw-thread connects pressure cap 7, also be provided with joint ring 8 between pressure cap 7 and the spherojoint 5, but by rotation pressure cap 7 press seal rings 8, thereby make sealing between spherojoint 5 and the lower ball base 1.Described spherojoint 5 inside are provided with packing rubber cushion 16 on some groups, be provided with dividing plate 9 between the upper packing rubber cushion 16 of each group, upper packing rubber cushion 16 tops are provided with packing pressure cap 13, press down and upper packing rubber cushion 16 can be compressed by packing pressure cap 13, spherojoint 5 tops are connected with attaching nut 12 by screw thread, attaching nut 12 is externally connected to packing gland 14, wherein is connected with lower bull stick 12 on the attaching nut 12, and a side of packing box pressing cap 14 is connected with bull stick 11.When laying down gland for packing box 14, attaching nut 12 down twists, and packing pressure cap 13 exposes, solved when stingy pressure cap and the operation of old packing, and the problem that the gland for packing box internal thread damages, thus alleviate employee's labour intensity, improved managerial skills.
