AI Technical Summary
Traditional proportional valves cannot accurately maintain a stable negative pressure when the negative or positive pressure source fluctuates, resulting in low precision in adjusting the pressure and unstable pressure regulation function.
An electric vacuum proportional valve is adopted, which includes a valve body, a push device, a pressure detection device, and a control device. The pressure and vacuum level are detected in real time through gas pressure sensors and vacuum pressure sensors, and the gas input and output are adjusted by the control device to form a feedback control closed loop to ensure that the vacuum level of the air inlet chamber is stable at the set value.
This technology ensures that the vacuum level in the intake chamber remains stable even when there are fluctuations in the negative or positive pressure source, thereby improving the stability and pressure regulation accuracy of the proportional valve.
