detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this automatically full aligning suit cover modus ponens packing box comprise pressure cap 8, gland 7, close button stuffing box 6, bulb cylinder 5, moving ball headstock 4, sealing clamp 3, bulb pressure cap 2 and lower contact 1.Lower contact 1 lower end is connected with well head, lower contact 1 upper end counterbore is built-in with moving ball headstock 4, moving ball headstock 4 lower surface grooves are built-in with sealing ring, lower contact 1 upper end counterbore internal diameter and moving ball headstock 4 external diameters are poor is positive number, that is to say that lower contact 1 upper end counterbore internal diameter is larger than moving ball headstock 4 external diameters, moving ball headstock 4 can all around be moved in lower contact 1 upper end counterbore, reach tuningout object.Bulb cylinder 5 through holes are eccentric orfice, bulb cylinder 5 bottom bulb grooves are built-in with sealing ring, bulb cylinder 5 bottoms are placed in moving ball headstock 4, and be connected with lower contact 1 top by bulb pressure cap 2, on bulb cylinder 5 under bulb pressure cap 2, have sealing clamp 3, bulb pressure cap 2 internal diameters and sealing clamp 3 external diameters are poor is positive number, that is to say that bulb pressure cap 2 internal diameters are larger than sealing clamp 3 external diameters, make the sealing clamp 3 can translation all around in bulb pressure cap 2, reach tuningout object.Close button stuffing box 6 and be combined into tubulose by two semicircular, a semicircle lower end is welded with circular washer 9, circular washer 9 is convex inclined plane with junction, lunette termination, corresponding another lunette termination face that concaves, strengthen bonding strength by convex inclined plane, two ends, a semicircle middle part are connected with circular arc locating piece 11, closing button stuffing box 6 lower ends is threaded connection in bulb cylinder 5 top endoporus, close button stuffing box 6 and be built-in with packing, close button stuffing box 6 upper ends and be built-in with gland 7, pressure cap 8 is connected to and closes button stuffing box 6 upper ends.On pressure cap 8, be horizontally connected with jackscrew 10, via hole on corresponding gland 7.
When actual use:
The centering adjustment process of packing box: when safe handling, polished rod is through lower contact 1, moving ball headstock 4, the circular washer 9 that closes button stuffing box 6, gland 7, pressure cap 8 centre bores, and lower contact 1 lower end is connected with well head.Centering loosens being connected of bulb pressure cap 2 and lower contact 1 while adjustment, at this moment, bulb cylinder 5 can be all around with moving ball headstock 4 parallel, be placed in and close at the interior end of button stuffing box 6 with the packing circle of a standard, like this, just can ensure that polished rod is placed in the center of packing box lower port, then, lock being threaded of bulb pressure cap 2 and lower contact 1 again, complete the tuningout operation of packing box, the problem of the centering namely problem of tuningout is resolved.
The taking-up of packing, adition process: first pressure cap 8 and gland 7 are unclamped to the certain distance that moves up on polished rod, then with jackscrew 10, pressure cap 8 and gland 7 are fixed on polished rod, facilitate like this taking-up of packing or add operation, dismantle with the screw thread of lower contact 1 closing button stuffing box 6 again, close button stuffing box 6 from the interior taking-up of lower contact 1, to close button stuffing box 6 half upwards takes out from second half locating piece 11 again, packing is exposed on polished rod, packing can be taken out layer by layer or adds, after taking or adding, to close button stuffing box 6 half inserts in second half locating piece 11 from the top down again, and then button stuffing box 6 lower ends of closing that combine are threaded connection in lower contact 1 upper end, unclamp again jackscrew 10, gland 7 is pressed on packing, be threaded in and close button stuffing box 6 upper ends by pressure cap 8 again, compress gland 7, complete the taking-up of packing, add operation.
