Abstract
The utility model relates to a manual locking device used for a hydraulic control blowout preventer when a well is drilled or repaired. The manual locking device is characterized by comprising a piston rod, a manual locking rod, a shaft sleeve, a positioning pin and a manual opening pin, wherein the piston rod is axially in a threaded structure, the manual locking rod is connected with the piston rod in a threaded manner, the other end of the manual locking rod extends out of a piston cavity and is connected with the shaft sleeve outside the piston cavity into a coaxial body, and the shaft sleeve is fixed into a shaft sleeve seat for fixing the shaft sleeve and a piston into a coaxial body by the aid of a piston connecting rod. The manual locking device for a hydraulic control blowout preventer not only can realize manual locking of the blowout preventer after hydraulic closing, but also can realize manual opening of the blowout preventer by the aid of the manual opening pin in emergency of failure of a hydraulic control system of the blowout preventer and the like. Compared with a conventional manual locking device, the manual locking device is capable of further improving safety of well control equipment.
Description
Technical field
The utility model relates to the hydraulic control preventer that use in oil, natural gas well drilling well or workover treatment field, specifically, is hydraulic control blowout preventer manual locking device.
Background technology
When carrying out oil, natural gas well drilling well or carrying out workover treatment, need to use the hydraulic control preventer, when well kick or blowout occurring in the operation process, need close the hydraulic control preventer, according to the operational procedure requirement, for guaranteeing safety, avoid the blowout preventer hydraulic system to bear high pressure for a long time, after hydraulic pressure is closed the hydraulic control preventer, use manual locking device to lock, discharge the blowout preventer hydraulic system pressure then.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, hydraulic control blowout preventer manual locking device easy and simple to handle, it is in carrying out drilling well or workover treatment process, if when well kick or blowout, preventer to be in time closed, and manual locking will be carried out after closing with hydraulic pressure.
The technical solution of the utility model is: design a kind of hydraulic control blowout preventer manual locking device, it is characterized in that: it is made up of piston rod, manual locking bar, axle sleeve, alignment pin, manually opened pin, piston rod is helicitic texture vertically, the manual locking bar is connected with piston rod by screw thread, the axle sleeve that the manual locking bar other end stretches out outside plunger shaft and the plunger shaft is connected to same axis body, axle sleeve is fixed in the sleeve block, and sleeve block is fixed as same axis body by piston brace rod with axle sleeve and piston.
Described sleeve lining is processed with groove, is fixed with alignment pin on the manual locking bar, and alignment pin is positioned at groove.
Described axle sleeve and manual locking bar have through hole outside sleeve block, manually opened pin is by through hole connecting bushing and manual locking bar.
Advantage of the present utility model is: this hydraulic control blowout preventer manual locking device, it includes piston rod, manual locking bar, axle sleeve, alignment pin, manually opened pin.After blowout or well kick phenomenon occurring and closing the hydraulic control preventer, this device not only can be realized the manual locking of conventional hydraulic control preventer, but also can break down can not open preventer the time in hydraulic system, realizes the manually opened of hydraulic control preventer.The manual locking of preventer and manually opened action, simple to operate, rapid, reliability is high.Not only can realize conventional manual locking, also can break down to open the hydraulic control preventer time, realize the manually opened of hydraulic control preventer, effectively improve the safety of drilling well or workover treatment in hydraulic system.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Fig. 1 is a preventer opening example structure schematic diagram;
Fig. 2 is a blowout preventer manual locking back example structure schematic diagram;
Fig. 3 is an example structure schematic diagram when needing manually opened preventer.
Among the figure: 1, piston rod; 2, manual locking bar; 3, axle sleeve; 4, alignment pin; 5, manually opened pin; 6, sleeve block; 7, piston brace rod.
The specific embodiment
Embodiment as shown in Figure 1, hydraulic control blowout preventer manual locking device, it is by piston rod 1, manual locking bar 2, axle sleeve 3, alignment pin 4, manually opened pin 5 is formed, piston rod 1 is helicitic texture vertically, manual locking bar 2 is connected with piston rod 1 by screw thread, the axle sleeve 3 that manual locking bar 2 other ends stretch out outside plunger shaft and the plunger shaft is connected to same axis body, axle sleeve 3 is fixed in the sleeve block 6, sleeve block 6 is fixed as same axis body by piston brace rod 7 with axle sleeve 3 and piston, axle sleeve 3 inwalls are processed with groove, be fixed with alignment pin 4 on the manual locking bar 2, alignment pin 4 is positioned at groove, makes manual locking bar 2 can only carry out axially reciprocating; Axle sleeve 3 has through hole with manual locking bar 2 at sleeve block 6, and manually opened pin 5 is by through hole connecting bushing 3 and manual locking bar 2.When the blowout preventer hydraulic system breaks down can not open preventer the time, can pass through manually opened preventer, realize the manually opened of preventer.
When emergencies such as well kick, blowout occurring, hydraulic pressure is closed the hydraulic control preventer, is rotated counterclockwise axle sleeve 3 then, and the manual locking preventer is again with the hydraulic system pressure release; In the time of need opening preventer once more, the axle sleeve 3 that at first turns clockwise is removed manual locking, opens hydraulic system then, opens preventer.If hydraulic system breaks down, can not open preventer, can insert manually opened pin 5 this moment in the through hole of manual locking bar 2 and axle sleeve 3, and the axle sleeve 3 that turns clockwise then can be realized the manually opened of preventer.
As shown in Figure 2, preventer is in the manual locking state.When needs are opened preventer, should remove the manual locking state earlier, operate hydraulic system then, open preventer.Conventional hydraulic control blowout preventer manual locking device possesses manual locking and two functions of manual-lock preventer, and the manual locking device among the present invention can be realized the 3rd function on the above two basis, promptly manually opened preventer function.
As shown in Figure 3, the hydraulic control preventer is in open mode, when emergencies such as well kick, blowout occurring, hydraulic pressure is closed the hydraulic control preventer, then according to the operational procedure requirement, for guaranteeing safety, avoid the blowout preventer hydraulic system to bear high pressure for a long time, after hydraulic pressure is closed the hydraulic control preventer, use manual locking device to lock, discharge the blowout preventer hydraulic system pressure then.
