动态平衡电动二通阀 使用及安装说明书 Electric Dynamic Balancing Valve(For FCR)
用途:
本系列产品主要用于解决暖通空调系统中的水力失调问题,是集动态平衡和电动二通于一体的产品,特点是抗干扰能力强,控制精度高,在系统负荷波动较大的变流量系统中优势明显。
原理:
1 通过动态平衡功能动态平衡系统的阻力,保证设备输送介质流量在一定压差范围内不受系统压力波动影响,保持恒定。
2 根据设备的输入信号对电热式开关驱动器进行动作,实现阀的开关功能。
技术参数:
黄铜阀体(配电热式开关驱动器,可根据要求改变通电开关,具体参照电热头操作说明书)。

DESCRIPTION:
Oventrop electric dynamic balancing valve is used to solve the problem of hydronic maladjustment in heating and air conditioning system.It has combined two functions of dynamic balancing and electric on-off in one body.It has strong anti-jamming ability and high degree of accuracy,so it has good use in variableness flowrate system.
BASIC PRINCIPLE:
1 It dynamically balances system resistance by the function of dynamic balancing, and keeps the water flow rate invariableness while the system pressure fluctuate;
2 It regulates the on/off position of valve to pace the input signal, So it has the on/off function.
