The invention discloses a fluid flow resistance adjusting device which comprises a lock-shaped structure, a flow resistance adjusting pore plate and a sealing and filtering assembly. The flow resistance adjusting pore plate comprises a pore plate body, an O-shaped ring sealing groove, a working medium radial entering hole, a working medium axial entering hole and a throttling small hole. The sealing and filtering assembly comprises a first square soldering lug, a square filter net, a second square soldering lug, an annular filter net, an annular soldering lug and an O-shaped ring. The lock-shaped structure comprises a lock bottom channel and a guide boss. The diameter of a pore inside the pore plate is set to enable the pore plate to have different flow resistance characteristics, and therefore pressure adjusting requirements of an upstream pipeline system of a liquid engine and an electric thruster are met. The device integrates the functions of flow resistance adjusting, working medium filtering and detaching and can be placed in a pipeline connector according to using requirements, the space in the connector is sufficiently utilized, additional final assembly layout is not needed, the structure is compact, and the device has the advantages of being small in size, low in weight, high in reliability, convenient to install and detach, high in handleability and wider in application range.
Description
technical field [0001] The invention relates to the aerospace field, in particular to a fluid flow resistance adjusting device. Background technique [0002] When the electric thruster is discharging, the pressure of the working fluid at the cathode and anode inlets of the thruster must be the rated pressure to ensure the normal operation of the electric thruster. At present, the working fluid storage and supply system of aerospace electric propulsion usually adopts the micro-channel method to adjust the pressure of the working medium at the inlet of the cathode and anode, such as capillary, etching flow channel and other schemes. Due to the defects and instability of the manufacturing process, the actual flow resistance and There is a certain difference in the design value, which cannot meet the rated pressure requirements of the cathode and anode inlets of the electric thruster at the same time. [0003] When the chemical engine is ignited, the combustion chamber also nee...
