Abstract
The utility model relates to the fast separation device of pressure break high pressure pipe joint, comprise sealed packing, upper valve body, oil cylinder seat, upper valve body one end is union joint, and the other end has been bolted 8 limited blocks, bolt coat has preloading spring, and spring has certain pretightning force.Lower valve body one end is union joint, and the other end is placed in upper valve body inside, and limited block overcomes in the annular groove under initial tension of spring press-in in the middle part of valve body under piston action, and lower valve body is fixed.The switch in hydraulic control system can be operated, hydraulic oil enters oil cylinder from fuel inlet fitting, the elastic force that piston overcomes return spring under hydraulic fluid pressure effect moves to the left, and limited block outwards opens and loses fixing lower valve body under initial tension of spring effect, and upper and lower valve body can separate.
Description
art:
The utility model relates to a kind of fast separation device of pressure break high pressure pipe joint.
background technology:
Fracturing work is a kind of important measures of marine oil gas field development and volume increase.During the fracturing work of ocean, by high-pressure hose, the high pressure exhaust manifold on pressure break ship is connected with the wellhead assembly on ocean platform.For avoiding occurring that typhoon pressure break ship bumps against with ocean platform under sea beat, the high pressure pipe joint Quick release be connected need be withdrawn rapidly pressure break ship with platform.Current domestic ocean pressing crack construction ground zero, safety management is specification not too, and job location is mostly in the neritic area that the weathers such as the Bohai Sea are relatively gentle, the probability encountering typhoon is relatively little, therefore usually adopts manual operation to be thrown off by the high pressure pipe joint connected between pressure break ship and ocean platform.Along with China's marine oil gas field development is more and more to deep-sea regional development, during construction operation, may typhoon be encountered at any time, and jolting of sea beat when typhoon occurs and hull, be difficult to the disengagement being realized high pressure pipe joint by manual operation.
summary of the invention:
The purpose of this utility model is to provide a kind of pressure break high pressure pipe joint fast separation device, realizes the automatic quick separating of high pressure pipe joint between pressure break ship and platform.
The utility model is achieved through the following technical solutions above-mentioned purpose:
This fast separation device comprises upper valve body, lower valve body, oil cylinder seat, oil cylinder, piston, return spring, limited block, preloading spring, indicator, back leakage connection, fuel inlet fitting, it is characterized in that: upper valve body one end is union, middle part is fixed with oil cylinder seat, oil cylinder is connected with oil cylinder seat by screw thread, piston oil cylinder inner and and have return spring between oil cylinder seat, the other end has been bolted 8 limited blocks, bolt coat has preloading spring, and limited block outwards opens under initial tension of spring effect; Lower valve body one end is union, and the other end is placed in upper valve body inside and is sealed by sealing ring, and there is one annular groove at middle part, and limited block overcomes in initial tension of spring press-in annular groove under oil cylinder effect, thus upper and lower valve body is linked together.When running into typhoon, can operate the switch in hydraulic control system, hydraulic oil enters oil cylinder from fuel inlet fitting, and piston overpowers return spring elastic force moves to the left, it is spacing that limited block outwards tilts and loses lower valve body under initial tension of spring effect, namely realizes the disengagement of upper and lower valve body.When using hydraulic system to throw off inefficacy, also manually can throw off bolt and piston overpowers spring force is moved to the left, thus make upper and lower valve body separately.Because indicator and piston link together, whether can separate according to position judgment two valve body of indicator.
beneficial effect:
The beneficial effects of the utility model are: owing to have employed pressure break high pressure pipe joint fast separation device, solve the problem of high pressure pipe joint Quick release between pressure break ship and platform when typhoon appears in fracturing work, pressure break ship is avoided to bump against ocean platform, for ocean pressing crack construction provides safety guarantee.

Detailed description of the invention:
See Fig. 1, Fig. 2, this separator by sealed packing (1), upper valve body (2), oil cylinder seat (3), oil cylinder (4), return spring (5), piston (6), preloading spring (7), bolt (8), limited block (9), indicator (10), lower valve body (11), back leakage connection (12), fuel inlet fitting (13), manually throw off bolt (14) and form.Upper valve body (2) one end is union joint, the other end is fixed with 8 limited blocks (9) by bolt (8), bolt (8) overcoat has preloading spring (7), and spring (7) has certain pretightning force, and limited block (9) can outwards open under the pretightning force effect of preloading spring (7).Lower valve body (11) one end is union joint, and it is inner that the other end is placed in upper valve body (2), and limited block (9) overcomes in the annular groove under the press-in of spring (7) pretightning force in the middle part of valve body under piston (6) effect, and lower valve body is fixed.Oil cylinder (4) and oil cylinder seat (3) are threaded connection and are fixed on upper valve body (2) middle part, and are respectively equipped with fuel inlet fitting (13) and back leakage connection (12), and have return spring (5) between oil cylinder seat (3) and piston (6).Indicator (10) is connected with piston (6) and moves with piston and mobile.Be provided with two at oil cylinder (4) near lower valve body (11) one end and manually throw off bolt (14).
When ocean pressing crack construction, in the high pressure pipe joint that fast separation device is connected with ocean platform at pressure break ship by the union jiont treatment at two ends, when running into the emergencies such as typhoon, the switch in hydraulic control system can be operated, hydraulic oil enters oil cylinder (4) from fuel inlet fitting (13), the elastic force that piston (6) overcomes return spring (5) under hydraulic fluid pressure effect moves to the left, limited block (9) outwards opens and loses fixing lower valve body (11) under spring (7) pretightning force effect, and upper and lower valve body can separate.Whether indicator (10), owing to linking together with piston (6) and moving with it, can separate according to the position judgment upper valve body (2) of indicator, lower valve body (11).When hydraulic system fails, by operate manually throw off bolt (14) piston (6) is moved to the left and realize upper valve body (2), lower valve body (11) be separated.
