Abstract
The invention relates to an offshore emergency fast separating device for a high-pressure pipeline. The fast separating device mainly comprises a fast female joint (1), female joint cover plate pressing bolts (2), ball pin locking parts (3), a fast male joint (4), a male joint piston pressing spring (5), a female joint piston pressing spring (6), a female joint wedge-shaped piston (7), a female joint cover plate (8), a male joint cover plate (9) and a male joint wedge-shaped piston (10). The female joint cover plate (8) is fixed to the fast female joint (1) through the six female joint cover plate pressing bolts (2); the fast male joint (4) and the fast female joint (1) are connected and fixed through the six ball pin locking parts (3) uniformly distributed along the axis. The female joint wedge-shaped piston (7) and the male joint wedge-shaped piston (10) are pressed through the female joint piston pressing spring (6) and the male joint piston pressing spring (5). Under the emergency circumstance, the high-pressure pipeline can be separated fast, operation is easy, accuracy is high, and the fast separating device has high application value for the high-pressure operation pipeline.
Description
Technical field: the present invention relates to emergency escape machinery, particularly marine emergent high pressure pipe line Quick release device.
Background technique: at present, marine operations involving high pressure gets more and more, but for the sea situation of complexity, safety precautions is perfect not enough, when meeting with the harsh conditions such as typhoon, billow, undercurrent, tsunami, operations involving high pressure pipeline cannot depart from time, causes pipeline to be washed away by damage, billow, also can cause casualties time serious, great loss is caused to marine operations involving high pressure.
Summary of the invention:
In order to avoid high pressure pipe line cannot depart from and the injury caused in time in emergency situations, the invention provides a kind of marine emergent high pressure pipe line Quick release device, the quick disengaging of high pressure pipe line can not only be realized, high-pressure liquid can also be avoided to gush out, avoid casualties, and alleviate the damage of equipment to a certain extent.
The technical solution adopted for the present invention to solve the technical problems is: marine emergent high pressure pipe line Quick release device two ends are connected on high pressure pipe line, the complete geometry of head regular hexagon structure of quick tool joint pin and quick female joint under the normal bonding state of device is closed, and is locked by ball stud; Tool joint pin cover plate intersects 30 degree with female joint cover plate mounting point, is fixed by 6 cover plate hold-down bolts and quick pin and box sub, fast female joint; Quick tool joint pin and quick female joint are connected and fixed along the equally distributed ball stud locking member of axis by 6; Ball stud locking member comprises again: ball stud hold-down bolt, ball stud holddown spring, ball stud, tool joint pin pushing pin axle sleeve, tool joint pin pushing pin holddown spring, tool joint pin pushing pin, high-pressure oil duct, 7 component edge axis arrangements successively when bonding state, wherein ball stud head is spheroidal structure, afterbody is identical with tool joint pin pushing pin structure, be stepped straight pin, high-pressure oil duct is positioned at tool joint pin inwall, is uniformly distributed around quick tool joint pin axis; Tool joint pin wedge plungers and female joint wedge plungers head are wedge shape round table surface, and afterbody is round column structure, and around uniform 14 through holes of axis, ensure high-pressure liquid normal through.
Sea provided by the invention high pressure pipe line Quick release device advantage applies of meeting an urgent need exists:
1. this device can realize the quick disengaging of high pressure pipe line in emergency situations;
2., while this device realizes departing from fast, employ the sealing that two kinds of methods ensure that high-pressure liquid, safe and reliable;
3. this device can realize collision installation, without the need to manually, uses manpower and material resources sparingly;
4. this apparatus parts is regular, just with processing, can produce in batch on a large scale;
5. this device can be widely used in all kinds of operations involving high pressure scene, as offshore oil and gas volume increase drilling operation ship, offshore work platform etc.
Accompanying drawing illustrates:
Fig. 1 is the emergent high pressure pipe line Quick release device structural representation in the present invention sea.
Fig. 2 is the partial enlarged drawing of structure 3 ball stud locking member in Fig. 1.
Fig. 3 is the schematic diagram that this structure is applied to ocean platform marine riser and departs from fast.
1. quick female joints in figure, 2. female joint cover plate hold-down bolt, 3. ball stud locking member, 4. quick tool joint pin, 5. tool joint pin piston holddown spring, 6. female joint piston holddown spring, 7. female joint wedge plungers, 8. female joint cover plate, 9. tool joint pin cover plate, 10. tool joint pin wedge plungers, 11. ball stud hold-down bolts, 12. ball stud holddown springs, 13. ball studs, 14. tool joint pin pushing pin axle sleeves, 15. tool joint pin pushing pin holddown springs, 16. tool joint pin pushing pins, 17. high-pressure oil ducts.In Fig. 3 I is the emergent high pressure pipe line Quick release device in the present invention sea.
Embodiment:
With reference to figure 1 and Fig. 2, when there is emergency, pressurize at control port, manifold pressure raises, and high pressure oil promotes tool joint pin pushing pin 16 by high-pressure oil duct 17, and then promotes ball stud 13, ball stud 13 and quick tool joint pin 4 is forced to depart from, under the effect of tool joint pin piston holddown spring 5 and female joint piston holddown spring 6, tool joint pin wedge plungers 10 and female joint wedge plungers 7 head extrude mutually, impel being separated of quick tool joint pin 4 and quick female joint 1 parts entirety; When quick tool joint pin 4 is separated completely with quick female joint 1, the sphenoid surface of tool joint pin wedge plungers 10 and female joint wedge plungers 7 and the sphenoid surface of respective piston cover plate are combined closely, and wedge plungers afterbody upper-end surface and piston cover plate interior edge face are fitted, ensure that the sealing of two segment pipes after being separated; The places such as this device can be arranged on bottom offshore platform according to actual needs, sea bottom surface, operations involving high pressure ship line ports.
