Application of Automatic Control System for Water Conservancy Valves


 

 

       Tilt sensors are widely used in automatic control systems for hydraulic valves. Currently, the front-end equipment of the flap-type water valve control system generally consists of a flap water valve, an oil cylinder, and a cable-type valve opening gauge fixed on the oil cylinder. The oil cylinder is connected to the upper end of the valve through a rotating shaft, and the extension and contraction of the oil cylinder drive the opening and closing of the valve. During the extension and contraction of the oil cylinder, the cable also extends and contracts, and there is a certain functional relationship between them. As long as the length of the cable is measured, the real-time angle of the gate can be calculated. However, since the external cable is exposed, it is easily eroded, leading to instability in the opening gauge. Therefore, in recent years, new non-contact control technologies have gradually been adopted, specifically using tilt sensors to measure the angle of the oil cylinder in a non-contact manner, which can effectively compensate for the shortcomings of the original system.
