Description:

电动两通阀 CKD1

◆ 产品简介

CKD1系列开关式电动阀由VA7010系列阀门驱动器和CKD系列铜阀门组成。用于控制冷水或热水空调系统管道的开启或关闭,达到控制室温之目的。驱动器由单向磁滞同步马达驱动,阀门弹簧复位。阀门不工作时处于常闭状态,当需要工作时,由温控器提供一个开启信号,使电动阀接通交流电源而动作,开启阀门,冷冻水或热水进入风机盘管,为房间提供冷气或暖气;当室温达到温控器设定值时,温控器令电动阀断电,复位弹簧使阀门关闭,从而截断进入风机盘管的水流。通过阀门关闭和开启,使室温始终保持在温控设定的温度范围内。CKD1系列电动阀的驱动器与阀门采用螺纹联接方式,可在阀门安装之后,再安装驱动器。现场装配,接线灵活、方便。驱动器之平面设计可以贴近墙面安装,占用空间小。产品可靠耐用,工作噪音低,并能在隐蔽式风机盘管装置内常出现的高温高湿环境可靠工作。

◆操作及注意事项

马达罩壳应防止滴水渗入。当阀装于水平管道时,安装位置及平面夹角不超过85°,如图二所示。当阀门装在垂直管道上时,马达罩壳必须防止漏水渗入。

拨动手动操作杆时应缓慢移动,当手动杆沿箭头指向慢慢移动并按入缺口内卡住,阀门处于常开状态,每当电流首次通过电动阀门时,手动杆会再设定至自动位置。

 

◆安装须知

常闭二通阀和分流三通阀的安装如图三、四、五所示。对于高层建筑物,应在底层支管上采用减压阀。安装阀体时,应注意阀体箭头指向。若带有辅助开关,其接线如图6所示。
