Abstract

The invention discloses a mixing ratio multi-opening regulating valve of a liquid rocket engine. The mixing ratio multi-opening regulating valve of the liquid rocket engine comprises a valve body, a main inlet which is formed in one end of the valve body and communicated with a propellant main path, a main outlet which is formed in one side of the valve body, a main valve core which is movably arranged in the valve body and used for adjusting the circulation area of the main inlet and the main outlet through the position change, and an opening degree adjusting mechanism which is arranged in the valve body and used for driving the main valve core to move in the valve body. As the opening degree adjusting mechanism can drive the displacement of the main valve core, the opening degree of thevalve can be accurately controlled according to working conditions, and therefore the mixing ratio of propellants can be accurately adjusted; and compared with the prior art, the mixing ratio is adjusted directly on the propellant main path, other related valves are not need to be installed, the adjusting method is efficient and convenient, the complexity of the control system is low, the space occupation is small, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of liquid rocket engines, in particular to a mixing ratio multi-opening regulating valve of liquid rocket engines. Background technique [0002] With the development of aerospace technology, a wide variety of aerospace equipment has been extensively studied. [0003] The main source of power for aerospace equipment is the rocket, and the most important part of the rocket is the rocket engine. The rocket engine (rocket engine) is powered by the aircraft's own propellant (energy), which can work in the space outside the dense atmosphere. The energy is converted into the kinetic energy of the working medium (working medium) in the rocket engine, which forms a high-speed jet and is discharged to generate thrust. According to the state of the propellant, rocket engines can generally be divided into liquid rocket engines using liquid propellants, solid rocket engines using solid propellants, or solid-liquid hybri...
