Air path inserting-pulling combined connector

Abstract

The invention discloses an air path inserting-pulling combined connector, comprising a socket on a rocket, a connector body, a ball lock, a cylinder and a steel rope, wherein the socket on the rocket and a rocket body are in threaded connection; the connector body is positioned below and is contacted with the socket on the rocket; the ball lock is in threaded connection with the connector body; the upper part of the cylinder is fixedly connected with a connection rod in the ball lock; the lower part of the cylinder is fixedly connected with the steel rope; one end of the steel rope is connected with the cylinder; the other end of the steel rope is fixed on an external launcher frame. The ball lock also comprises a lock body, a lock cylinder, a steel ball, a lock cylinder spring, the connection rod, a first guide pin, a movable sleeve, a movable sleeve spring, a second guide pin and a third guide pin. By applying the air path inserting-pulling combined connector, the fast and reliable separating between the connector body and the socket on the rocket can be realized.

Description

technical field [0001] The invention relates to the field of rocket fueling and gas supply, in particular to a gas path plug-in combination connector. Background technique [0002] The gas circuit connector is the interface device connected between the ground gas supply system and the booster stage or core stage gas circuit valve on the rocket. Connection and accurate separation. [0003] At present, our country has developed a variety of gas path connectors and successfully applied them in launch vehicles and missile weapon systems. Among them, the three-tube cold helium connector is mainly composed of connector components, locking mechanism, shedding mechanism, cylinder combination, solenoid valve, control cable and other components. The locking mechanism is provided with a locking chamber, and the shedding mechanism is provided with an unlocking chamber. When the three-tube cold helium connector assembly is docked with the socket on the arrow, the locking signal is tran...

AI Technical Summary

Problems solved by technology

[0004] During the actual launch of the launch vehicle, some gas supply projects require the ground gas supply system to supply gas until the rocket takes off. However, the existing gas circuit connector needs to be transmitted by the control cable after the gas supply project is completed. When the valve is energized, the solenoid valve acts to deflate the locking chamber and supply air to the unlocking chamber through the combination of cylinders, and then complete the disconnection of the connector, which obviously cannot meet the technical requirements for rapid detachment when the rocket takes off.
