Abstract
The utility model relates to an adjustable blowout prevention box of a belt conveyor, which consists of a back pressure cap, a packing, a bushing, a secondary packing box, a primary packing box, a ball joint, a pressure plate, a support ring, a nut and a lower joint, wherein the support ring is arranged at the central part of the lower joint, a ball joint sphere is arranged in the support ring, the pressure plate is sleeved at the other end of the ball joint, and the inner diameters of the support ring and the pressure plate are smaller than the outer diameter of the ball joint sphere; the nut is fixedly connected with the lower joint; the ball joint is welded with a first-level packing box; 6-8 packing sets are arranged in the first-level packing box, and the bushing is pressed on the packing in the first-level packing box; 6-8 packing sets in this second grade packing box, pushes down the packing in the second grade packing box with another benefit core, and second grade packing box and one-level packing box threaded connection, back pressure cap install on second grade packing box. The adjustable blowout prevention box is a main part for connecting a pumping well down-hole pipe column and a pumping unit, and is mainly used for sealing a pumping rod and preventing crude oil at a well head from overflowing.
Description
Technical field
The utility model relates to a kind of oil pumper well head blowout hookup.
Background technology
Conveyor blowout prevention box weight is big at present, adopt screwed connection with well head, and well head adopts clamp connection more, needs supporting clip head during installation, has increased workload; The blowout prevention box body adopts screw to connect, and when changing packing, need unload four screws of pine earlier, changes the one-level packing, unloads four screws again, changes the secondary packing, and operation is loaded down with trivial details; And not possessing the function of well head tuningout, packing is easy to wear.
The utility model content
The technical problem that the utility model will solve provides the connected mode that the adjustable blowout prevention box of a kind of conveyor changes conveyor blowout prevention box and well head, reduces the time of installing and changing packing, realizes the function of well head tuningout.
For solving the problems of the technologies described above; The utility model conveyor is adjustable, and the blowout prevention box is made up of rear pressing cap 1, packing 2, benefit core 3, secondary packing box 4, one-level packing box 5, spherojoint 6, platen 7, support ring 8, nut 9 and lower contact 10; Wherein, above-mentioned support ring 8 is installed in lower contact 10 centres, and above-mentioned spherojoint 6 spheroids one end is positioned in the support ring 8; Above-mentioned platen 7 is nested with on spherojoint 6 other end spheres, and this support ring 8 is all little than spherojoint 6 spheroid external diameters with platen 7 internal diameters; Above-mentioned nut 9 is fixedly connected with lower contact 10; Above-mentioned spherojoint 6 and 5 welding of one-level packing box; Dress 6-8 root packing 2 in this one-level packing box 5, above-mentioned benefit core 3 is pressed on the packing 2 in the one-level packing box 5; Dress 6-8 root packing 2 is mended core 3 with another and is pushed down the packing 2 in the secondary packing box 4 in the above-mentioned secondary packing box 4, and this secondary packing box 4 is threaded with above-mentioned one-level packing box 5, and above-mentioned rear pressing cap 1 is installed on the secondary packing box 4.
Above-mentioned one-level packing box 5 is 6 with secondary packing box 4 interior packing 2 quantity.
Adopt the present technique scheme; The utility model conveyor is adjustable, and the blowout prevention box has alleviated the weight of conveyor packing box, has simplified the workload that packing box is installed, when changing packing; Need not the dismounting screw; Reduce operating procedure and stopped the well time, possessed the function of well head tuningout simultaneously, reduced the eccentric wear of oil well.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further explain.
Fig. 1 divides the structural representation of the adjustable blowout prevention box of conveyor for the utility model.
The specific embodiment
As shown in Figure 1, during blowout prevention box assembling that the utility model conveyor is adjustable support ring 8 is installed in lower contact 10 centers, platen 7 is placed on the spherojoint 6; With tightening between spherojoint 6 and the one-level packing box 5, weld, again spherojoint 6 is placed on the support ring 8; Cover upper cap nut 9 is tightened, and compresses spherojoint 6 through platen 7, and 6-8 root packing 2 is packed in the one-level packing box 5; Push down packing 2 with mending core 3, in addition 6-8 root packing 2 is packed in the secondary packing box 4, mend core 3 with another and push down packing 2; Then secondary packing box 4 and one-level packing box 5 are tightened, at last rear pressing cap 1 is installed on the secondary packing box 4, material is processed by No. 45 steel.
During blowout prevention box installation that this conveyor is adjustable adjustable blowout prevention box of conveyor and well head are adopted clamp connection, when replacing packing in back is installed, directly unload the packing box pressure cap; Just replaceable; Increase a ball-type joint simultaneously newly, possess the function of well head tuningout, played the effect of well head tuningout simultaneously.
