Abstract

The invention relates to an integrated flow jetting device capable of achieving repeated jetting and a flow jetting method, and belongs to the technical field of flow jetting. The integrated flow jetting device comprises a flow jetting tank, a flow jetting tank piston, a nozzle, a supply tank, a supply tank piston, a spring and at least two self-pressurization gas generators. The flow jetting tankis located in the supply tank, and the flow jetting tank and the supply tank are combined to form a nested structure. The flow jetting tank piston is located in the flow jetting tank, and the flow jetting tank piston and the flow jetting tank are combined to form dynamic sealing. The nozzle communicates with the first end of the flow jetting tank, and the self-pressurization gas generators communicate with the second end of the flow jetting tank. The supply tank piston is of an annular structure, is located in an interlayer formed by the supply tank and the flow jetting tank, and is combinedwith the supply tank and the flow jetting tank to form dynamic sealing. The first end of the supply tank communicates with the first end of the flow jetting tank, the second end of the supply tank communicates with the second end of the flow jetting tank. One end of the spring is connected with the supply tank piston, and the other end of the spring is connected with the second end of the supply tank. The integrated flow jetting device can achieve jetting at least twice, and the phenomenon that remediation cannot be achieved after jetting has a fault at the first time is avoided.

Description

technical field [0001] The invention relates to an integrated jet device capable of multiple injections and a jet method, belonging to the field of jet technology. Background technique [0002] With the development of spacecraft on-orbit service technology, on-orbit assembly and on-orbit construction will become a reality. On-orbit assembly and on-orbit construction of spacecraft have requirements for temperature control and environmental protection on the outer surface. Therefore, there is a need for a jet device capable of thermally controlling or spraying protective liquid paint on the outer surface of a spacecraft in orbit to form a protective layer. [0003] At present, the jet device that can be used for on-orbit injection includes a jet tank and a self-pressurized gas generator, and the gas generated by the self-pressurized gas generator pushes the liquid paint in the jet tank to be sprayed onto the surface of the spacecraft. [0004] The existing jet device can onl...
