Valve Control Method and Control Terminal

Abstract

A valve control method comprises: configuring a condition for periodically triggering self-cleaning; and when a valve is continuously in an opened or closed state, or a preset time point is reached, repeatedly opening and closing the valve several times within a short period of time, such that dirt on a contact surface of a valve element is automatically removed by means of vertical or rotational movement of the valve element so as to prevent the case in which the valve is in a static state for a long period of time which causes impurities in a pipeline to be deposited on the surface of the valve element, and thereby causing the valve element to jam or have increased movement resistance. In addition, the resilience of mechanical parts such as a spring and a rubber member in the valve is not reduced as a result of the valve being in the closed or opened state for a long period of time, and the flexibility thereof is maintained. Also disclosed is a valve control terminal. In the control method and the control terminal, a valve body does not need to be disassembled, and no hardware needs to be added. The invention is easy to implement, and greatly improves the reliability of a valve.
