1. At the same time with dynamic balance and electric adjustment of two functions, and two functions simultaneously. The dynamic balancing electric regulating valve is installed on the return pipe of the combination air conditioner and the fresh air unit. For the air conditioning terminal equipment that needs to adjust the flow at any time, the valve can be controlled by weak electricity to receive voltage or current signals, and according to the set temperature requirement and The actual temperature changes in a timely manner proportional integral adjustment flow regulation, at the same time due to the valve's own hydraulic automatic adjustment orifice can be based on different pressure changes automatically maintain the same pressure within the valve, the set flow Automatically maintain a constant, not subject to interference from the pressure changes in the system, so as to adjust the amount of water change, both timely adjustment of water volume, but also timely adjustment of the water volume to ensure a constant, to avoid the valve adjustment caused by changes in system pressure Mutual interference, instantaneous overcurrent, system oscillation and other dynamic imbalance, making the central air conditioning water diversion energy distribution purposes of the full realization. 

2. Dynamic balance electric valve can be in the smallest to the maximum flow range of 50 kinds of flow settings, in order to ensure that the maximum signal to receive the required equipment to control the rated flow. 
This function also ensures the dynamic balance of the same specification. When controlling the end devices of different rated water volume, the electric regulating valve also receives the largest electric signal and gives different rated water volumes to meet the needs of different devices. Therefore, when selecting the dynamic balancing electric regulating valve at the terminal equipment, it is not necessary to add other types of balancing valves to conduct initial regulation, which can solve the problem of static imbalance of the system. 


3. Has a spring constant pressure membrane components constitute a mechanism that can automatically adjust the pressure inside the valve body, so that flow control sleeve before and after the pressure is always constant. 
So as to ensure that this valve has both electric adjustment function and dynamic balance function, and the two functions simultaneously. 


4. With the weak with dynamic balance Electric control valve in the electric regulation and the ordinary electric control valve is the same, are the control region of the temperature deviation from the set temperature to accept weak system controller to give the standard electric signal (0 - 10V or 2 - 10 V., 0 - 20mA or 4 - 20mA) to drive the valve actuator, adjust the valve opening. 
Wiring with weak mode: According to different signals weak, according to different ways of wiring.


Dynamic balance of electric control valve through the principle of temperature control, the use of human experience or computer input automatic temperature control curve program, based on thermal load and outdoor temperature changes, according to the need to control the flow of electric valve adjustment, the water temperature or for, The average return water temperature remains constant. 


The valve is in the constant pressure conditions, the electronic control flow so that the electric control valve flow from the pipe network pressure fluctuations. 
Based on this differential pressure compensation function, the influence of the control valve on the control of the dynamic flow changes of each branch and the main pipe is isolated. The control valve controls each branch to become an independent system, maintaining the relative stability and the hydraulic balance of each branch. When a system traffic changes or users continue to expand or unravel a loop, the other loops are not affected. Change the complex and variable parameters, fuzzy control of uncertainty as a single parameter accurate control. It provides the best solution for pipe network automation. For the system reliable, energy-saving operation has laid a solid foundation.
