Abstract

The invention provides a step-less adjustment valve and a liquid rocket. The step-less adjustment valve comprises a main shell, a liquid inlet and a liquid outlet formed in the main shell and furthercomprises a valve cup arranged in the main shell, a shift structure, and a driving device, wherein the valve cup is provided with a cup opening communicated with the liquid inlet and a flowing throughopening molded in the cup wall, and the flowing through hole communicates with the liquid outlet; the shift structure is movably arranged on the outer surface of the cup wall of the valve cup; and the driving device is connected with the shift structure and drives the shift structure to reciprocate in a linear mode on the valve cup so as to change the flowing through area of the flowing through hole.

Description

technical field [0001] The invention relates to the technical field of liquid rocket flow valves, in particular to a steplessly adjustable valve and a liquid rocket. Background technique [0002] In the liquid rocket hydraulic system, the thrust adjustment function of the reusable cryogenic liquid oxygen methane engine needs to be realized through the regulating valve in the system medium pipeline. By controlling the throttling area of ​​the throttling element, the regulating valve changes the flow and pressure of the flowing medium, thereby adjusting the medium flow and mixing ratio entering the downstream system, thereby realizing the function of controlling the engine thrust. [0003] In the existing liquid rocket launch system, the adjustment value of the control valve is discontinuously distributed in a point shape, which leads to a limited adjustment range. Considering the large adjustment range of the engine thrust and the improvement of the engine's own adjustment ab...
