Abstract
A packing case enabling quick replacement of packing comprises a press cap, a gland, a packing case inner body, a packing case outer body and a rubber gate, and is characterized in that the upper part of the packing case inner body is in threaded connection with the press cap, the lower part thereof is in threaded connection with the upper end of the packing case outer body, the lower end of the packing case outer body is in threaded connection with the rubber gate, a cavity of the packing case inner body is internally provided with the packing, and the gland is arranged between the packing case inner body and the press cap. The packing case has the advantages that the packing can be taken out for one time by virtue of the packing case inner body and can be pushed out from clearance between baffles at the lower end of the packing case inner body; the replacement of the packing is convenient and quick, and is time saving and labor saving.
Description
Technical field
The utility model relates to a kind of pumpingh well well head packing box, and specifically a kind of quick formula is changed the packing packing box.
Background technology
At present the oilfield pumping well well head not just, the phenomenon ubiquity of polished rod eccentric wear packing causes that to change packing work more frequent; Used in addition packing box structure is unfavorable for changing packing; Need when changing packing owing to be in the position of dark place, to pluck out packing difficulty especially plucking out singly with screwdriver the slit of packing between polished rod and packing box; Change two people of a packing and operate and need more than one hour time, rate when having influenced the production of oil well.
Summary of the invention
The order of the utility model provides a kind of quick formula and changes the packing packing box, overcomes the difficult problem of replacing packing that above-mentioned prior art exists.
The technical scheme of the utility model realizes in the following manner:
The utility model comprises pressure cap, gland, packing box endosome, packing box ectosome and rubber gate; It is characterized in that packing box endosome top links to each other with the pressure cap screw thread; The bottom links to each other with packing box ectosome upper end screw thread; Packing box ectosome lower end links to each other with rubber gate screw thread, in packing box endosome cavity, is provided with packing, between packing box endosome and pressure cap, is provided with gland.
The packing box endosome is made as tubular, and upper diameter is greater than lower diameter, and the end in the bottom is provided with the baffle plate of inside symmetry, is provided with rotary handle at the middle part on top, is provided with male thread in the handle top and the bottom.
The utlity model has through the packing box endosome and once propose packing, the advantage of from the gap of the baffle plate of packing box endosome lower end, once releasing packing, it is convenient and swift, time saving and energy saving to change packing.

The structural representation of accompanying drawing-the utility model
1-pressure cap 2-gland 3-packing box endosome 4-packing box ectosome 5-rubber gate among the figure
The specific embodiment
For further disclosing the technical scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
The utility model comprises pressure cap 1, gland 2, packing box endosome 3, packing box ectosome 4 and rubber gate 5; It is characterized in that packing box endosome top links to each other with the pressure cap screw thread; The bottom links to each other with packing box ectosome upper end screw thread; Packing box ectosome lower end links to each other with rubber gate screw thread, in packing box endosome cavity, is provided with packing, between packing box endosome and pressure cap, is provided with gland.
When changing packing, at first shut down, pressure cap 1 is unloaded; Make gland 2 break away from packing, and pressure cap 1 gland 2 height are suspended on the polished rod, unload packing box endosome 3; From packing box ectosome 4, propose, from the gap of the following end-stopping plate of packing box endosome 3, once eject packing and take off, refill new packing and install and get final product with screwdriver or club; The replacing packing is efficient and convenient, and is time saving and energy saving.
