This invention provides a pressure self-balancing regulating valve based on the stress transmission of a flexible bladder, comprising a valve body, a
differential pressure diaphragm core, a balancing plug, a compensating diaphragm, a dynamic flow stabilizing valve, a fine-tuning
buoyancy ball, a buffer chamber, a flow resistance adjusting rod, and a pressure
equalization resonant cavity. The valve senses the inlet and outlet
pressure difference in real time through the
differential pressure diaphragm core, driving the balancing plug and flow resistance adjusting rod to automatically adjust the flow cross-sectional area. The compensating diaphragm and dynamic flow stabilizing valve optimize the flow field, the fine-tuning
buoyancy ball compensates for high-frequency disturbances, the
resonant cavity suppresses pressure pulsation, and the buffer structure absorbs
impact energy. It also integrates a
sewage discharge filter and a flow guiding and pressure stabilizing structure, possessing advantages such as self-cleaning,
low noise, energy saving, and no external power source required. The overall structure requires no
electrical control, offers fast response, high precision, and strong anti-interference, effectively solving the problems of traditional pressure reducing valves such as
lag, easy clogging, and poor flow stability.
