Description
technical field [0001] The invention relates to a liquid pressure regulating device, in particular to a high-pressure miniaturized liquid pressure regulating device. Background technique [0002] As a self-operated regulating device, the liquid pressure regulating device changes the flow rate and kinetic energy of the liquid medium by adjusting the area of the orifice, resulting in different pressure losses, and relies on the energy of the medium itself to automatically maintain the outlet pressure. , so as to achieve the purpose of adjusting the pressure, it is widely used in aerospace power systems. At present, the gas pressure regulating or decompressing device is usually applied directly to the liquid medium, or the liquid pressure regulating device is designed using the design idea of the gas pressure regulating device. The existing liquid pressure regulating device has large volume and weight, and poor adjustment accuracy. The problem. Contents of the invention ...
