Described blowout prevention box 15 is made up of blowout prevention box cavity 9, blowout prevention sealing-plug 10, sealing-plug pull bar 19, pull bar basal disc 20, pull bar basal disc 20 is threaded with blowout prevention box cavity 9, sealing-plug pull bar 19 1 ends link together by axle and pull bar basal disc 20, the other end is welded with blowout prevention sealing-plug 10, described pull bar basal disc 20 is provided with conical seal (contact) face, matches with blowout prevention sealing-plug 10.
This packing box is provided with three grades of packing chambeies, and blowout prevention box 15 upper ends are one-level packing chamber 16, and blowout prevention box 15 lower ends are secondary packing chamber 17, is three grades of packing chambeies 6 between the bulb of secondary packing chamber 17 and bulb dish 5.
The utility model compared with prior art has the following advantages:
1, solved because polished rod is disconnected deviates from packing box and cause problem of environmental pollution, reduced staff labor intensity, reduced material consumption, improved managerial skills.
2, energy automatic deflection adjusting under the bulb effect prevents eccentric wear.
3, can prevent effectively that under the effect of blowout prevention box disconnected bar gas blowout accident ground from taking place.
4, compact conformation, high pressure resistant, reduce packing and change the time, prolong packing application life.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of blowout prevention multifunctional high pressure packing box, by packing box clamping disk(-sc) 1, packing box supporting positive cover 2, the packing box body, packing box clamping cap 13, packing box screwed cap 11 is formed, packing box clamping disk(-sc) 1 blocks packing box supporting positive cover 2 usefulness clamps, the top of the packing box clamping disk(-sc) 1 packing box body that has been threaded, packing box clamping cap 13 has been threaded above the packing box body, the outer wall of packing box clamping cap 13 is connected with the inner thread of packing box screwed cap 11, described packing box body is by bulb dish 5, clamping cap 3 under the packing box, packing box intermediate sleeve 8, clamping cap 7 on the packing box, blowout prevention box 15 is formed, the bulb of bulb dish 5 is threaded by clamping cap under the packing box 3 with packing box clamping disk(-sc) 1, the bulb of bulb dish 5 is provided with joint ring 4, bulb supporting positive cover 18 and packing box intermediate sleeve 8 are installed in the bulb dish 5, the upper end of bulb dish 5 is threaded with blowout prevention box 15 by clamping cap on the packing box 7, clamping cap 7 is to be provided with packing box pad 12 on the upper end of bulb dish 5 and packing box, and blowout prevention box 15 upper end outer walls are connected with packing box clamping cap 13 inner threads.
