Embodiment two:
Oil drilling remote control diameter variable stabilizer, unlike embodiment one, conversion seat 20 lower surface is machined with and is uniformly distributed
Six radially screw inclined planes and six radially perpendiculars, there are equally distributed six radially spiral shells reducing positioning body 22 upper surface
Rotation inclined-plane and six radial direction perpendiculars, there are six supporting legs of equally distributed long, medium and short its underpart, and positioning seat 24 top has
Equally distributed deep, in, shallow six grooves；Five equally distributed circular radials it are machined with in the middle part of every spiral boss of housing 1
Hole.
Oil drilling remote control diameter variable stabilizer is accessed drilling tool, connects mud circulation canal.
For the first time after turn on pump, under flowing mud momentum effect, signal valve pocket 8, power piston 9 and mandrel 14 are to moving down
Dynamic, drive cushion rubber 10, thrust bearing A 11, the spring seat of honour 12, gland 15, oblique orbit 17, reducing positioning body 22, thrust bearing B
23, back-up ring B 26 moves down, and spring A 13 and spring B 19 are compressed, on it by the spring seat of honour 12 and oblique orbit 17 respectively simultaneously
End face moves down, and reducing piston 18 is push by oblique orbit 17 and is displaced outwardly simultaneously, simultaneously power piston 9 to compensating piston 28 it
Between hydraulic fluid pressure in annular sealed space raise, promote compensating piston 28 to move down with gag lever post 29, compensating piston 28
Between bottom pipe nipple 33, three radial holes on support set 27 of the mud in annular space, drainage screen 31 are outside to housing 1
Flowing, the radial direction screw inclined plane after two support leg of drawing money on credit of reducing positioning body 22 bottom is shallow with two of positioning seat 24 top
When groove radial direction screw inclined plane below contacts, reducing positioning body 22 starts radially screw inclined plane and rotates, when its lower surface
When touching with the bottom connection of two shallow grooves on positioning seat 24 top, above-mentioned mobile parts stop mobile, and reducing piston 18 is outside
Arc surface arrive the little path position of oil drilling remote control diameter variable stabilizer set, the bottom of signal valve head 7 is still positioned at
In the bottom endoporus of signal valve pocket 8, relatively big to the resistance of flowing mud, instrument produces bigger pressure drop, compensates work simultaneously
The mud filling in 28 bottoms stops to housing 1 flows outside, and now it uses as path regulator；
After termination of pumping, mud impulse force disappears, and the above-mentioned spring A 13 compressed resets with spring B 19, and its upper surface moves up,
Promote the spring seat of honour 12, thrust bearing A 11, cushion rubber 10, power piston 9, signal valve pocket 8, mandrel 14, oblique orbit 17, pressure simultaneously
Set 15, back-up ring B 26, thrust bearing B 23, reducing positioning body 22 move up, and reducing piston 18 is hauled by oblique orbit 17 simultaneously
Moving inward, between power piston 9 to compensating piston 28, the hydraulic fluid pressure in annular sealed space reduces simultaneously, outside housing 1
The mud in portion three radial holes on drainage screen 31, support set 27 annular between compensating piston 28 to bottom pipe nipple 33 is empty
In flowing, promote compensating piston 28 to move up with gag lever post 29, equally distributed when on reducing positioning body 22 upper surface
When four radial direction screw inclined planes contact with four radial direction screw inclined planes on conversion seat 20 lower surface, reducing positioning body 22 starts
Radially screw inclined plane rotates, when its four radially perpendicular contacts with four radial direction perpendiculars of conversion seat 20,
Above-mentioned mobile parts stop mobile, and reducing piston 18 is pulled back to the position before turn on pump, and the mud outside housing 1 stops to compensation
Flow in annular space between piston 28 to bottom pipe nipple 33；
For the second time after turn on pump, under flowing mud momentum effect, signal valve pocket 8, power piston 9 move down with mandrel 14, band
Dynamic cushion rubber 10, thrust bearing A 11, the spring seat of honour 12, gland 15, oblique orbit 17, reducing positioning body 22, thrust bearing B 23, gear
Circle B 26 moves down, and spring A 13 and spring B 19 are compressed by the spring seat of honour 12 and oblique orbit 17 respectively simultaneously, its upper surface
Moving down, reducing piston 18 is push by oblique orbit 17 and is displaced outwardly simultaneously, ring between power piston 9 to compensating piston 28 simultaneously
Hydraulic fluid pressure in shape confined space raises, and promotes compensating piston 28 to move down with gag lever post 29, compensating piston 28 under
Between portion's pipe nipple 33, three radial holes on support set 27 of the mud in annular space, drainage screen 31 are to housing 1 flows outside,
Radial direction screw inclined plane after two support leg of drawing money on credit of reducing positioning body 22 bottom and two deep grooves on positioning seat 24 top
When radial direction screw inclined plane below contacts, reducing positioning body 22 starts radially screw inclined plane and rotates, when two of its underpart
Short supporting leg radial direction screw inclined plane below contacts with the radial direction screw inclined plane after two shallow grooves on positioning seat 24 top
Time, reducing positioning body 22 continues radially screw inclined plane and rotates,
When its lower surface bottom connection with four grooves on positioning seat 24 top respectively touches, above-mentioned mobile parts stop moving
Dynamic, the big path position of the oil drilling remote control diameter variable stabilizer of the arc surface arrival setting outside reducing piston 18, signal valve
The bottom endoporus of the bottom separating signal valve pocket 8 of 7, less to the resistance of flowing mud, instrument produces less pressure drop,
The mud of compensating piston 28 bottom stops to housing 1 flows outside simultaneously, and now it uses as regulator, big footpath；
For the second time after termination of pumping, mud impulse force disappears, and the above-mentioned spring A 13 compressed resets with spring B 19, and its upper surface is upwards
Mobile, promote the spring seat of honour 12, thrust bearing A 11, cushion rubber 10, power piston 9, signal valve pocket 8, mandrel 14, oblique orbit simultaneously
