Principle and specification of electric ball valve
The author: Time:2020/10/10

        电动球阀工作原理是由蓝色的执行器带动阀体中的球型密封阀门做90°的旋转,实现阀体的导通与关闭,达到控制介质通断目的。选择的电动球阀应具有小体积,合理结构,执行机构全部密封,防水性好,可在恶劣场合使用。
        电动球阀技术特点有:电动球阀是以大功率电动机为动力驱动球型阀,阀的开与闭是利用定位准确的微触点开关与电子控制器转换来实现:仅需220V, 50Hz 交流电源:控制方式简单——三根控制线断开状态对应阀门全部关死状态。两根控制线短接状态(不需外加电源),对应阀门全部打开状态;全流量、阻力小、体积小,打开或关闭时间约8s。
