动态平衡电动二通阀在制冷和供热系统中，风机盘管通常由电动二通阀控制。当一些风机盘管关闭时，其他运行的风机盘管流量进口动态平衡电动二通阀2.jpg将增加，引发室温波动。STV系列是集动态流量平衡阀和电动二通阀于一体的产品，由电热执行器控制。在阀门开启时，通过动态平衡阀的恒流作用维持流经设备的流量不变而不受系统压力波动的影响，使控制精度更高。在制冷或供热系统中，当室温达到房间温控器设定值时，房间的温控器发送信号到电热执行器，令阀门关闭。当室温或低于设定温度时，房间温控器发送信号到电热执行器，令阀门开启。通过阀门关闭和开启，使室温始终保持在房间温控器设定的温度范围内。内置平衡阀芯会自动保持流量恒定 RETZ dynamic balance electric two-way valve In refrigeration and heating systems, fan coil units are usually controlled by electric two-way valves. When some fan coils are closed, the flow of other fan coils in operation will increase, causing room temperature fluctuations. STV series is a product integrating dynamic flow balance valve and electric two-way valve, which is controlled by electric actuator. When the valve is opened, the constant flow of the dynamic balance valve keeps the flow through the equipment unchanged without being affected by the system pressure fluctuation, so that the control accuracy is higher. In the refrigeration or heating system, when the room temperature reaches the set value of the room temperature controller, the room temperature controller sends a signal to the electric actuator to close the valve. When the room temperature is higher or lower than the set temperature, the room temperature controller sends a signal to the electric actuator to open the valve. By closing and opening the valve, the room temperature is always kept within the temperature range set by the room temperature controller. The built-in balance valve core will automatically keep the flow constant.
