Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 upper press cover, 2 packing boxs, 3 polished rods, 4 packings, 5 gate valve main bodys, 6 gate valve axles, 7 shut-in well balls, 8 plugs, 9 springs, 10 large pads, 11 minipads, 12 screw rods, 13 screw sleeves, 14 swivel nuts, 15 handles.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
Fig. 1 is structural representation of the present utility model, and anti-breaking bar injecting glue grain blowout preventer, comprises upper press cover 1, packing box 2 as shown in the figure, upper press cover 1 is contained in the top of packing box 2, and upper press cover 1 center has the hole passed for polished rod 3, packing box 2 is built with multiple packing 4, and packing 4 holds polished rod tightly.Described packing box 2 side is provided with gate valve main body 5, and gate valve main body 5 is for hollow and gate valve main body 5 is installed with gate valve axle 6, and gate valve axle 6 laterally has through hole, namely can be opened by rotating gate valve shaft or the inner passage of closing gate valve main body 5.Gate valve main body 5 is connection glue injection grain cylinder outwards, inwardly communicate with the cavity between packing 4 and packing box 2, micelle is injected to the cavity between packing 4 and packing box 2 by injecting glue grain cylinder, micelle is elastic caoutchouc particle, elasticity extruding can be carried out, when packing 4 is subject to necessarily wearing and tearing, because micelle has certain gap and elasticity to packing 4, can the wearing and tearing of automatic compensation packing 4, therefore make greatly extend the application life of packing 4.
Due in process of production, often there is the disconnected de-phenomenon of polished rod 3, and polished rod 3 disconnected de-after, because well head is opened, easily cause the generation of production accident.In the utility model, there is the cavity outwards extended described upper press cover 1 side, and cavity is built with shut-in well ball 7, and shut-in well ball 7 diameter is greater than the hole on upper press cover 1, cavity end plug 8 shutoff, and described cavity floor is downward-sloping inclined-plane.Due to the inclined-plane that cavity floor is downward-sloping, therefore, shut-in well ball 7 has the trend of rolling downwards, and when polished rod 3 proper motion, shut-in well ball 7 is extruded to side, is positioned at cavity; When polished rod 3 disconnected de-after, shut-in well ball 7 rolls along inclined-plane, has blocked the hole on upper press cover 1, has automatically shunt in a well, the generation of Accident prevention.
In the utility model, between described shut-in well ball 7 and plug 8, spring 9 is also housed, when ball 7 of shunting in a well is pressed towards, spring 9 produces certain elastic force effect to shut-in well ball 7, and when polished rod 3 breaks de-, shut-in well ball 7, under elastic force effect, more easily rolls.
Pad is all equipped with in described packing about 4 two ends, and pad comprises large pad 10 and minipad 11, and large pad 10 is positioned at the outside of minipad 11, and minipad 11 diameter is less than large pad 10 diameter, and the diameter of large pad 10 is less than again packing box 2 internal diameter.Due to the unique design of pad size, make the utility model can automatic deflection adjusting, the wearing and tearing to packing box 2 when reducing polished rod up-downgoing.Further, the 1cm less of large pad 10 diameter of minipad 11 diameter described in the utility model, the diameter 1cm less of packing box 2 internal diameter again of large pad 10, make like this utility model can in the scope of 0-12mm automatic deflection adjusting.
In the utility model, described injecting glue grain cylinder comprises screw rod 12 and screw sleeve 13, and screw rod 12 front end is by being threaded in screw sleeve 13, and screw sleeve 13 other end connects gate valve main body 5.When screw rod 12 is back-outed, in screw sleeve 13, form cavity, for holding micelle, after screw sleeve 13 connects gate valve main body 5, opening gate valve axle 6, being slowly screwed into screw rod 12, micelle and squeezedly compress into gate valve main body 5, and then enter packing box 2.
In order to prevent screw rod 12 from deviating from, the entrance point that described screw sleeve 13 is screwed at screw rod 12 is also equipped with swivel nut 14, and the tail end of screw rod 12 is equipped with handle 15, mainly in order to easy to operate.
Due to gate valve axle 6 serious wear in use, therefore, described gate valve axle 6 is designed to taper, the little head end of taper pierces into front end nut shutoff after gate valve main body 5, and such gate valve axle 6 revolves more tight, also any leakage can not occur even if occur to wear and tear.
During construction, first anti-breaking bar injecting glue particle blowout preventer is connected tightly with well head, put into large pad 10 and minipad 11 successively, install long-acting wear resistant packing 4, fill up micelle, put into minipad 11 and large pad 10 again, open the plug 8 on upper press cover 1, take out shut-in well ball 7, upper press cover 1 and packing box 2 top are tightened, now, after polished rod 3 is passed from packing box 2 and upper press cover 1, be loaded on shut-in well ball 7, twist good plug 8, finally injecting glue grain cylinder and gate valve main body 5 are connected tight, and micelle is injected in packing box 2, open simultaneously and take out, the standard of injecting glue grain has a temperature to be advisable when being and normally working with polished rod 3, but must not scald one's hand.When maintaining at ordinary times, if find polished rod 2 have band oil band water time, do not need shut down, as long as injecting glue grain cylinder and gate valve main body 5 are connected; first revolve after a few circle screw rod 12 has certain pressure, then open gate valve axle 6, continue rotary screw 12; after having noted, first closing gate valve axle 6, then back out injecting glue grain cylinder.
Packing 4 overlength in application life of the present utility model (1-3 changes once), only need to some micelle makeup energy of packing box 2 note at ordinary times, once completing to two minutes, do not need to shut down, doing so avoids all disadvantages brought because often changing packing 4, can also oil be increased simultaneously, greatly reduce the labour intensity of workman; Can automatic deflection adjusting, deflection-regulating range is 0-12mm; In use procedure polished rod 3 disconnected de-after can automatically shunt in a well, reduce hidden danger.
