proportion valve
1.The control of followed valve and the modified nero PID control of proportion valve and the resisting saturation of integral control of switch valve and the voltage comparing control of switch valve was analyzed. The experiment data was given out,and their capabilities were analyzed.
2.The concentration of irrigation liquid is regulated by manual flux adjusting valve in order to fulfill the proportion fertilizing of water-saving micro-irrigation & drip irrigation system.
3.In conseguence,the valve proportion of input and out-put is 1: 5, The altitude in transplantingthis kind of trees is 1200m or so above tke sea level at the Qin-Yi River Valley,1500M at the Dadu River Valley.
4.Diesel speed and load signals were sent into Electronic Control Unit (ECU), these real-time operating condition signals were analyzed and treated by the control center, and then based on the experimental results the opening time of electromagnetic valve was controlled to realize online water-injection adjusting and optimum water-fuel proportion.
