Title:
PRESSURE REGULATING SYSTEM AND PRESSURE REGULATING SYSTEM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/155275
Kind Code:
A1
Abstract:
A pressure regulating system and a pressure regulating system control method. The pressure regulating system comprises a fluid inlet (100) and a fluid outlet (200). The pressure regulating system further comprises: a pressure regulating loop (1), two ends of the pressure regulating loop being respectively communicated with the fluid inlet and the fluid outlet; an automatic valve (2) which is arranged at an inlet end of the pressure regulating loop and is communicated with the pressure regulating loop; a first cut-off valve (3) which is arranged on the pressure regulating loop and is communicated with the pressure regulating loop, an inlet end of the first cut-off valve being communicated with the fluid inlet; and a pressure regulating assembly (4) which is arranged on the pressure regulating loop and is communicated with the pressure regulating loop, the pressure regulating assembly being located at the end of the automatic valve away from the first cut-off valve. The pressure regulating system and the pressure regulating system control method can exert a protective effect on the subsequent pressure regulating assembly, so that a fluid cannot be directly flushed into the pressure regulating assembly and thus cause damage to components, especially a pressure regulating valve in the pressure regulating assembly, thereby prolonging the service life of the pressure regulating valve.
