One end of the locking mechanism is arranged on the shell through a pin; the other section of spherical joint is arranged in the locking piston; a bearing assembly on the locking mechanism is clamped in a locking groove of the shell; the locking piston is placed in an oil through hole in the shell, and is compressed by the locking spring; the locking spring seat is fixedly arranged on the shell through a fastening piece; the adjustable spring rod is arranged in the locking spring seat and compresses the locking spring; the oil through hole in the shell is arranged between the locking spring seat and the locking piston; the inner sleeve is fixedly arranged on the shell; one end of the self-sealing valve is compressed by the self-sealing valve spring; and the other end of the self-sealing valve compresses the inner sleeve.
Description
Technical field
The utility model belongs to the pipeline interconnection technique, relates to the locking mechanism that a kind of air refuelling butt joint is thrown off.
Background technology
Air refuelling refers to utilize tanker aircraft to give aloft aircraft supply fuel oil, and this mode can effectively increase fighting range and the direct route ability of operational aircraft, expands the whole fighting capacity of air force.
Most widely used tanker refuelling system is flexible pipe-taper sleeve type fuel loading system in the world at present, adopts this kind mode to carry out air refuelling, and an important link is exactly butt joint, the disengagement that is subjected to oily plug and fueling connection.
Adopt the air refuelling butt joint to throw off locking mechanism, the oil circuit when guaranteeing to refuel is unobstructed, and the little amount of leakage during disengagement ensures air refuelling safety, has been applied in the air refuelling gondola at present.
The utility model content
The purpose of this utility model: propose the locking mechanism that a kind of air refuelling butt joint is thrown off, butt joint can form when throwing off that oil circuit is self-styled, coupling mechanism force changes with oil pressure.
Technical solution of the present utility model: the locking mechanism that a kind of air refuelling butt joint is thrown off comprises self-styled shutter spring, self-styled valve, interior cover, adjustable spring bar, locking spring seat, latching ram, locking spring, catch gear, housing.Catch gear one end is contained on the housing with pin, another section ball-and-socket type joint places in the latching ram, bearing assembly on the catch gear is stuck in the locking slot of housing, latching ram is placed in the housing oil through, and compress with locking spring, the locking spring seat is fixed on the housing with fastener, and the adjustable spring bar is contained in the locking spring seat, the compression locking spring, the housing oil through places between locking spring seat and the latching ram; Interior cover is fixed on the housing, and self-styled valve one end compresses with self-styled shutter spring, and the other end compresses interior cover.Be pressed with rubber on the contact surface of cover and self-styled valve, sleeve in described.
Advantage of the present utility model and beneficial effect: the utility model plays the asphalt channel effect under mated condition, when disengaged condition, can realize self-styled to oil circuit; The coupling mechanism force of the utility model locking mechanism increases with the increase of oil pressure, guarantees under the little pressure butt joint easily, is not easy to throw off under the big pressure, ensured add, refueled aircraft be subjected to oily process; The utility model is short in the transition response time that is converted to disengaged condition by mated condition, also have only spillage seldom, a large amount of pollution or the potential dangers that cause of leaking of liquid when having avoided mode of operation to throw off even can guarantee under the state of big flow flow of liquid release suddenly.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Wherein cover, 4-adjustable spring bar, 5-locking spring seat, 6-locking spring, 7-housing, 8-latching ram, 9-catch gear, 10-bacterium shape valve, 11-sleeve, 12-locking key in the self-styled shutter spring of 1-, the self-styled valve of 2-, the 3-.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Consult Fig. 1, locking mechanism comprises self-styled shutter spring 1, self-styled valve 2, interior cover 3, adjustable spring bar 4, locking spring seat 5, latching ram 8, locking spring 6, catch gear 9, housing 7.Catch gear 9 one ends are contained on the housing 7 with pin, another section ball-and-socket type joint places in the latching ram 8, bearing assembly on the catch gear 9 is stuck in the locking slot of housing 7, latching ram 8 is placed in housing 7 oil throughs, and compress with locking spring 6, locking spring seat 5 usefulness fasteners are fixed on the housing, and adjustable spring bar 4 is contained in the locking spring seat 5, compression locking spring 6, housing 7 oil throughs place between locking spring seat 5 and the latching ram 8; Interior cover 3 is fixed on the housing 7, and self-styled valve 2 one ends compress with self-styled shutter spring 1, cover 3 in the other end compresses.Be pressed with rubber on the contact surface of cover 3 and self-styled valve 2, sleeve 11 in described.
In the utility model docking operation, sleeve 11 contacts with interior cover 3 and forms sealing, catch gear 9 is lifted and depresses locking key 12 by the conical surface, make the fixing and bacterium shape valve 10 of sleeve 11 move on and back down self-styled valve 2, form oil circuit, catch gear 9 falls in the locking slot, and coupling mechanism force relies on spring 6 and oil pressure to provide, oil pressure is more big, and coupling mechanism force is more big; In the disconnecting process, bacterium shape valve 10 withdraws from self-styled valve 2, and sleeve 11 contacts with bacterium shape valve 10 under action of the spring, realizes that oil circuit is self-styled, and self-styled valve contacts with interior cover 3 under the effect of spring 1, realizes that oil circuit is self-styled.The utility model has solved that air refuelling adds, the asphalt channel during the refueled aircraft butt joint, oil circuit is self-styled during disengagement, and the coupling mechanism force of its locking mechanism increases with the increase of oil pressure simultaneously, guarantees that butt joint easily under the little pressure, be not easy to throw off under the big pressure, ensure the safety of refueling process.
