Description
Technical field
The invention belongs to feed flows, gas exhaust piping interface between carrier rocket lift-off technology field more particularly to rocket and ground.
Background technique
The medium-and-large-sized carrier rocket of a new generation using zero second for having the unlock in advance of ball lock, pre-separation plus lets out exhaust connection at present
Device, arrow interface be straight-through structure, interior media pressure to arrow interface parting surface generate axial separation force it is larger, because
And the pulling force that ball lock carries needed for working normally is higher；To break down when preventing fall off within connector zero second, thus take ball
Lock unlocks in advance, the scheme that connector pre-separation is supported.When this kind of connector scheme unlocks in advance there are still ball lock
The pulling force of a possibility that failure, ball lock carrying are higher, force pull-off force also excessively high, bigger than normal to load on arrow；Ball is set simultaneously
Lock, support two kinds of docking concepts of docking mechanism, organization plan are complicated；This kind unlock in advance, the connector of pre-separation, can not expire
After sufficient pre-separation, rocket is persistently added and unusual service condition releases the emergency disposals requirements such as gas supply.
Summary of the invention
The technical problem to be solved by the present invention is overcome the deficiencies in the prior art, the present invention provides a kind of ball lock type connection
