Embodiment
The particular content of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, horizontal bar self cleavage formula high temperature blowout preventer, including：Main body 1, in the main body 1
Left end is provided with left plate 2, and the right-hand member of main body 1 is provided with right plate 3, passes through bearing 4 and lock nut 5 in the left plate 2
Rotation is provided with rotating threaded shaft 6, and spring 7 and sliding block 8, the left end and rotating threaded shaft of spring 7 are provided with the rotating threaded shaft 6
6 offset, and the left end of the right-hand member and sliding block 8 of spring 7 offsets, the right-hand member of sliding block 8 and the neck 10 being arranged on the mobile left end of leading screw 9
Be engaged, three sections of screw threads be provided with described mobile leading screw 9, be arranged on the mobile left end of leading screw 9 for the first left-handed thread section
91, be arranged on the middle part of mobile leading screw 9 for right-handed thread section 92, be arranged on the mobile right-hand member of leading screw 9 for the second left-handed thread section
93, divide between the first left-handed thread section 91 and right-handed thread section 92 and between the left-handed thread section 93 of right-handed thread section 92 and second
Escape 94 is not provided with, and the left end of mobile leading screw 9 is arranged in rotating threaded shaft 6, and the mobile middle part of leading screw 9 is arranged on bar shaped nut
In 11, leading screw spacer 12 is connected with the left side of the bar shaped nut 11, connection is connected with the right side of the bar shaped nut 11
Bolt 13, attaching nut 14 is provided with the right side of connecting bolt 13 and shears right flashboard 15, the right flashboard 15 of shearing is with cutting
Cut left flashboard 16 to cooperate, the left flashboard 16 of shearing is arranged on the right side of elevated-temperature seal flashboard 17, elevated-temperature seal flashboard
17 square nut 18 that passes on left is connected with the right-hand member of mobile leading screw 9.
The operation principle of above-mentioned horizontal bar self cleavage formula high temperature blowout preventer is：As shown in Fig. 2 using can be manually rotated spanner up time
Pin rotates rotating threaded shaft 6, in the neck 10 for the left end that sliding block 8 is pushed into mobile leading screw 9 by the spring 7 in rotary screw 6, sliding block 8
Rotating threaded shaft 6 and mobile leading screw 9 are combined into together.I.e. rotating threaded shaft 6, which turns clockwise, mobile leading screw 9 while turns clockwise,
Now the inner joining threads of rotating threaded shaft 6 do not promote the mobile side-to-side movement of leading screw 9, because mobile leading screw 9 drives in rotating threaded shaft 6
It is lower to turn clockwise, because bar shaped nut 11 is shifting of the right-handed thread under the drive for the leading screw 9 that turns clockwise gradually to the left
It is dynamic, pull the right flashboard 15 of shearing to be moved to the left；Square nut 18 is left hand thread under the drive of the leading screw to turn clockwise simultaneously
Gradually movement to the right, promote elevated-temperature seal flashboard 17, the left flashboard 16 of shearing to move right, shear right flashboard 15 with shearing left lock
Plate 16 is mutually closed, and THE ADIABATIC SHEAR IN is realized to the cable in well head 20 in wellhead flange 19 and wirerope.As shown in figure 3, now silk
Thick stick spacer 12 releases sliding block 8 completely separable in the neck 10 in the left side of mobile leading screw 9, while compression spring 7 is to dead point；Continue suitable
Hour hands rotate rotating threaded shaft 6, and mobile leading screw 9 starts to move right due to completely disengaged in the presence of left hand thread, promotes high
Warm sealing damper 17, the left flashboard 16 of shearing and the right flashboard 15 of shearing move right together, until reaching the center of well head 20 and resistance to height
Warm seal receptacle fits untill reaching shut-in well completely.As shown in figure 1, when opening well head if desired, then rotate counterclockwise rotates
Leading screw 6 drives mobile leading screw 9 to be moved to the left until reaching dead point, until mobile leading screw 9 not untill being moved to the left, leading screw spacer
12 are moved to the left to boost sliding block 8 not influence to move leading screw 9 under the promotion of bar shaped nut 11 and reach dead point, now rotating threaded shaft 6
Screwed up with mobile leading screw 9 for together with, continue rotation counterclockwise, shifted dynamic leading screw 9 and promote bar shaped nut to drive 11, the right flashboard 15 of shearing
Move right, while pull square nut 18 to drive elevated-temperature seal flashboard 17, the left flashboard 16 of shearing to be moved to the left up to well head 20 is complete
Untill full opening.
