The invention discloses a miniaturized liquid pressure regulating device. The miniaturized liquid pressure regulating device comprises a pressure regulating device housing with an inlet and an outlet,and a plug cap arranged at the upper end of the pressure regulating device housing, wherein an O-shaped rubber seal is arranged between the plug cap and the pressure regulating device housing; a valve element module is arranged in an inner cavity of the housing, and comprises a valve element basal body and a plastic block; a balance ring, a cylindrical spring, a spring base and a spring outer sleeve are bonded at the lower end of the pressure regulating device housing in sequence from top to bottom; a spring washer and a nut are arranged below the balance ring; the nut is connected with the valve element module; O-shaped rubber seals are arranged between the balance ring and the valve element module and between the balance ring and the pressure regulating device housing; the spring outersleeve is in threaded connection with the pressure regulating device housing; the mounting force of the cylindrical spring is adjusted through rotating the spring outer sleeve; and the spring outer sleeve is locked through a locking nut. The miniaturized liquid pressure regulating device has the advantages of small size, light weight, high adjusting precision, long service life and miniaturization.
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 ...
