Three-way pressure reducing valve, flushing method thereof, hydraulic balancing system, and system flushing method

Abstract

The application discloses a three-way pressure reducing valve and a flushing method, a hydraulic balance system and a system flushing method, and relates to the technical field of fluid equipment maintenance. The three-way pressure reducing valve comprises a pilot valve, a flushing pipeline, a ball valve, a first compression spring and a first spring cavity; and a main valve, the main valve comprising a main valve body, a second compression spring, a second spring cavity and a control valve core, the main valve body being provided with a first pipeline, a second pipeline, an oil return pipeline and an oil discharge pipeline; when the pressure of the second pipeline reaches between a first pressure value and a second pressure value, the ball valve is pushed open, and the pressure of the second pipeline is divided by the oil discharge pipeline; when the pressure of the second pipeline exceeds the first pressure value and the second pressure value, the ball valve is pushed open, the head of the control valve core moves left to compress the second compression spring, the control shoulder moves left, and the pressure of the second pipeline is divided by the oil discharge pipeline and the oil return pipeline. The three-way pressure reducing valve can make the pressure control of the second pipeline more stable.
