AI Technical Summary
Existing fluid control systems suffer from insufficient control precision, complex structure, and poor reliability when regulating flow rate and water pressure. In particular, electromagnetic components are prone to failure in humid environments or high-frequency use scenarios, and it is difficult to effectively control water pressure while regulating flow rate, resulting in unstable motor load or even damage.
By using a rotary control valve body, the water pressure of the inlet, outlet, and return water is controlled in a coordinated manner by selectively changing the orientation of the flow control channel. The flow rate is adjusted by mechanical rotation, and the return structure protects the motor to avoid overload.
It achieves precise regulation of flow rate and water pressure, improves system reliability and service life, reduces costs, protects the motor, adapts to the needs of different application scenarios, and avoids sudden changes in water pressure and motor damage.
