Problems solved by technology

[0004] The present invention provides a propellant delivery system, which aims to solve the problem that the control valve in the prior art propellant delivery system cannot automatically adjust the opening of the valve port when the air pressure in the air cavity of the storage tank is greater than the rated value, and it is easy to cause the propellant flow rate to be too high. Big problem causing engine damage and failure

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] In the propellant delivery system provided by the embodiment of the present invention, a valve stem is arranged in the casing of the control valve, and the cover plate on the valve stem is movably arranged in the installation cavity of the casing and forms a valve air cavity with the casing. The first valve of the valve stem The core is movable at the first valve port, and the valve air cavity is connected with the storage tank air cavity; when the air pressure in the storage tank air cavity is greater than the rated value, the gas in the valve air cavity will drive the valve stem to move, so...

Abstract

The present invention is applicable to the technical field of propellant delivery, and provides a propellant delivery system, which includes a storage tank and a control valve; the storage tank is provided with a storage tank air cavity and a storage tank liquid cavity; parts, and driving device; the shell is provided with an installation chamber, a valve liquid chamber with a liquid outlet and a liquid inlet, and a first valve port located between the liquid inlet and the liquid outlet is arranged in the valve liquid chamber, and the liquid inlet The port communicates with the liquid chamber of the storage tank; the valve stem includes a cover plate that is movably arranged in the installation chamber and forms a valve air chamber with the housing, and a first valve core that is movably arranged in the first valve port, and the valve air chamber communicates with the air chamber of the storage tank ; When the air pressure in the air chamber of the valve is greater than the rated value, the gas in the air chamber of the valve drives the cover plate to drive the first valve core to move to reduce the opening of the first valve port. The control valve of the propellant delivery system provided by the present invention can automatically reduce the opening of the first valve port when the air pressure in the air cavity of the storage tank is greater than the rated value, thereby ensuring the normal flow rate of the propellant and preventing engine damage and failure.

Description

technical field [0001] The invention relates to the technical field of propellant delivery, in particular to a propellant delivery system. Background technique [0002] When the engine of the spacecraft is working normally, it needs to deliver propellant of a certain rated flow rate to the engine through the propellant delivery system, and the flow rate of the propellant is directly affected by the air pressure in the air cavity of the storage tank; when the air pressure in the air cavity of the storage tank increases When , the flow velocity of the propellant flowing out of the liquid cavity of the tank increases; when the air pressure in the air cavity of the tank decreases, the flow velocity of the propellant flowing out of the liquid cavity of the tank decreases. [0003] In the prior art, the propellant in the tank liquid cavity of the tank in the propellant delivery system enters the control valve and is output to the engine from the control valve; when the air pressur...
