Abstract

The embodiment of the invention provides a combination valve, a rocket engine and a carrier rocket. The combination valve includes: a first valve and a second valve connected to each other; a first electromagnetic device of the first valve is configured to drive a first rod part of the first valve, so that a first valve element moves to a first port from a state of blocking a second port under the action of the first rod part to block the first port; the second electromagnetic device is configured to drive the second rod part, so that the second valve element moves from the state of blocking the fourth port to the direction away from the fourth port under the action of the second rod part, and a first design distance is formed between the second valve element and the fourth port; and the medium with the first design pressure flows through the third port, the second cavity and the fourth port in sequence. According to the combination valve, opening and closing of the first valve and the second valve are controlled through the two electromagnetic devices correspondingly, and the requirement for medium leakage under the low-pressure even zero-pressure-difference condition is met.

Description

technical field [0001] The present application relates to the technical field of launch vehicles, and in particular, to a combination valve, a rocket engine and a launch vehicle. Background technique [0002] In recent years, my country's aerospace industry has developed rapidly. The rocket engine with medium as propellant is one of the main choices for the power system of the launch vehicle. The rocket engine needs to be filled with the medium before starting, and it needs to be discharged from the pipeline and the assembly before filling. Excess gas or other substances to ensure the complete filling of the propellant, thereby ensuring the smooth and reliable start of the engine, and the media system also needs to be vented after the engine is shut down. Therefore, it is necessary to configure a relief valve for the rocket engine, and it is required that the relief valve can open the relief passage under high pressure, low pressure or even zero gauge pressure.
