Abstract
The utility model relates to a hydraulic automatic locking device for the ram of a blow-out preventer which belongs to the control device of petroleum and natural gas well, namely, a ram type blowout preventer assembly. The utility model is characterized in that the automatic locking of the ram of the blow-out preventer is achieved, and the exterior of the hydraulic automatic locking device automatically displays the states of the opening and closing positions of the ram synchronously; a display mechanism is composed of a display pole, a display block, a limit block, a grooved nut, etc. The utility model which has the advantages of convenient operation, fast and reliable locking, and labor intensity reducing can avoid an operation accident cased by a misoperation, applied to the single or double ram of the hydraulic blow-out preventers of various pressure levels and specifications.
Description
The utility model relates to ram block hydraulic automatic locking device, belongs to oil, natural gas well control equipment---ram blowout preventer parts.
Preventer is a necessary well-control equipment in probing of oil, natural gas and the formation testing process, is equipped with corresponding control system, can control blowout, well kick effectively, to safety with to finish every operation fast most important.The preventer of The field, flashboard type is in the majority, and the flashboard locking mode has manually and automatic two kinds, and hand locking flashboard speed is slow, poor reliability, labour intensity are big, and auto-locking suspension can overcome above-mentioned shortcoming, is developing direction.At present, homemade ram block locking mode is manually; Abroad, adopt the preventer of flashboard hydraulic automatic locking device to come out, locking device structure is not quite similar, all there is not the outside mechanism that shows flashboard open and close location status of preventer, thereby the operator can not intuitive judgment ram block present position state, easily causes the work accident that maloperation causes.
It is a kind of simple in structure that the purpose of this utility model is to provide, reliable lock, and volume is little, and is easy to operate, can externally show the ram block hydraulic automatic locking device of flashboard location status automatically.
The utility model is to adopt following technical proposals to realize: ram block hydraulic automatic locking device, comprise piston (1), latch segment (2), latching ram (3), fluid cylinder (10), cylinder cap (5), piston end cap (11), sealing ring (12), spring (13), flashboard axis (15) and liquid road, it is characterized in that having the outside mechanism that shows flashboard open and close location status automatically of cylinder cap.
The mechanism that shows flashboard open and close position in the technical solutions of the utility model constitutes by display pole (4), displaying block (6), sealing ring (7), channel nut (8) and with spacing stifled (9) that flashboard axis (15) fuses, displaying block (6) is when exposing cylinder cap, the expression flashboard is shown in an open position, when contracting to cylinder cap, flashboard is in the closed position.
The overhang of displaying block in the technical solutions of the utility model (6) outside cylinder cap can be adjusted, and its maximum overhang can reach 50% of cylinder cap thickness.
The utility model compared with prior art has the following advantages: when realizing the fast automatic locking of ram block, can be at the outside flashboard position of the switch state that shows automatically of preventer, avoid the maloperation in the operation, and it is simple in structure, reliable lock, volume is little, and is easy to manufacture, installation, use and easy to maintenance.
Be described further below in conjunction with accompanying drawing.
Figure one is the utility model ram block sectional view in the closed position.
Figure two is that the utility model ram block is shown in an open position sectional view.
With reference to figure one and figure two, the main piston (1) that latch segment (2), sealing ring (12) are housed connects with flashboard axis (15) by screw thread, flashboard axis (15) other end is equipped with the ram block (not shown), latching ram (3), spring (13), sealing ring (14) are loaded on main piston inside, compress and connect with piston end cap (11); Display pole (4) joins together with displaying block (6), links to each other with flashboard axis (15) with spacing stifled (9) by channel nut (8).The cylinder chamber of main piston left part is for opening the chamber, and the cylinder chamber of right part is for closing the chamber.When fluid power acts on when closing the chamber, promote main piston (1) and latching ram (3) and be moved to the left together, latching ram (3) the left end conical surface makes latch segment (2) that the trend of stretching out main piston (1) be arranged to the radial push component of latch segment (2).When the approaching end of main piston (1) stroke, latch segment (2) stretches out, and seat is on the step of fluid cylinder (10) the endless belt conical surface, at this moment, latching ram (3) external diameter becomes cylinder with the internal diameter of latch segment (2) and contacts, and main piston (1) is promptly locked, thereby realizes the flashboard automatic locking.Meanwhile, flashboard axis (15) drive displaying block (6) is contracted in the cylinder cap (5); When fluid power acts on when opening the chamber, at first promoting latching ram (3) moves as rightabout, spring (13) is compressed, the latch segment internal diameter becomes the conical surface gradually with the latching ram external diameter and contacts, latch segment (2) is under the effect of fluid cylinder (5) circular step conical surface radial component, be contracted in the main piston, realize the main piston release.Afterwards, main piston continues to move to opening direction, opens fully up to flashboard, promotes display pole (4) simultaneously, makes displaying block (6) stretch out cylinder cap.
The utility model is applicable to the hydraulic blow out preventer of various pressure ratings and specification, at first at latus rectum 230mm, use in the single, double flashboard type hydraulic blow out preventer of nominal pressure 70MPa, substituted the present domestic manual flashboard retaining mechanism that generally adopts, make this type preventer simple in structure, and reliable, volume and weight reduces to some extent rapidly in locking, and the every technical indicator of preventer meets or exceeds standard-required.
Claims (2)
1, ram block hydraulic automatic locking device, comprise main piston (1), it is characterized in that being equipped with on it latch segment (2) and sealing ring (12), main piston connects with flashboard axis (15) by screw thread, latching ram (3), spring (13) and sealing ring (14) are loaded on main piston inside, compress and connect fluid cylinder (10) and cylinder cap (5) sealed attachment with piston end cap (11), corresponding site is provided with the liquid road, has the outside mechanism that shows flashboard open and close location status automatically of cylinder cap.
2, according to the described ram block hydraulic automatic of claim 1 locking device, the mechanism that it is characterized in that showing flashboard open and close location status constitutes by display pole (4), displaying block (6), sealing ring (7), channel nut (8) and with spacing stifled (9) that flashboard axis (15) fuses.
