The Pressure-Continuously-Regulating Valve Based on NC Rotating

Abstract:

The creative thinking of the pressure -continuously-regulating device based on a NC rotary valve is introduced. Its inner structure, operating principle and technical feature are given out. The equation that gas flow and pressure changed with the rotation angle of the valve core is provided too. Stepper motor is used as its actuating device in this creative pressure -continuously-regulating device whose basic component is the specially designed, such as valve body, valve core and some common connections. Orifice area is changed by rotating the valve core controlled with a PC-controlled stepper motor which, and then an accurate adjustment of flow rate is thus ensured. As the change of the rotation angle is continuous, the flow rate also changes continuously, so the change of the pressure must be continuous.
