Supported rocket air supply connector

Abstract

The invention discloses a supported rocket air supply connector, which comprises a support plate and a plurality of air supply pipes. A plurality of through holes are formed in the support plate. Thethrough holes are stepped hole structures and the inner mesa of each through hole is a concave spherical surface. The lower end and the upper end of each air supply pipe are correspondingly provided with a nozzle joint and a cannula joint. A limiting ring table of which both sides are convex spherical surfaces is arranged on the outer circumferential wall of the nozzle joint. A sealing ring grooveand a sealing ring are arranged on the outer circumferential wall of the cannula joint. The nozzle joint passes through the through holes and is limited by a limiting sleeve. The limiting ring tableon the nozzle joint is located on the underside of the mesa in each through hole. The upper half of the limiting sleeve is rotatably mounted in the through holes and its upper end is located on the underside of the limiting ring table of the nozzle joint. The nozzle joint and the limiting ring seat are matched with the inner peripheral walls of the through holes at intervals. The inner peripheralwall of the limiting sleeve and the outer peripheral wall of the nozzle joint are matched at intervals. The supported rocket air supply connector has the advantages of simple structure, convenient operation, reliable sealing, and strong adaptability and can achieve long-term docking and zero-second shedding.

Description

technical field [0001] The invention relates to a rocket gas supply device, in particular to a supporting rocket gas supply connector capable of long-term docking and zero-second shedding. Background technique [0002] In the field of aerospace, a detachable gas supply socket is usually set at the tail end of the rocket, and multiple gas supply interfaces are set on the gas supply socket to realize the rapid docking and combined gas supply of multiple gas supply lines to ensure that nitrogen, air Reliable delivery of normal temperature gas. For the gas supply connector docked with the gas supply socket on the arrow, it should have the ability of long-term reliable docking to ensure the reliability of the gas supply; when the rocket is ignited and taken off, it should also be able to adapt to the slight drift of the rocket body when it is ignited and taken off And the ability to roll, and can achieve zero-second reliable shedding. Most of the existing air supply connectors ...

Problems solved by technology

Not only is its structure more complex, but there is a risk that it cannot be unlocked quickly

Especially for the air supply connector with ball lock structure, because the ball lock is a single-point failure mode mechanism, and in the process of long-term docking work, the moving parts of the ball lock have the risk of chemical and physical corrosion. Seriously affect its working performance, the risk of the air supply connector not being unlocked is higher
