Siphon type adjustment controller is through the use of time to adjust float chamber inlet flow and to implement the siphon drainage discharge siphon intermittent drainage regularly. It has the function of hydraulic automatic control device in the wave surge valve. Based on the characteristics of homemade wave surge valve of water and irrigation 's need, by analyzing the cycle time of water supply, mathematical model is set up.It can determine the siphon time to adjust the parameters of the controller and a...
