PVC塑料陶瓷芯球阀

功能介绍 Function introduction

PVC塑料陶瓷芯球阀是通过电机驱动阀杆带动阀芯动作的阀门，可分为关断和调节阀。关断即全开或关闭，可带反馈信号；调节可以通过时间、角度等方式稳定在某种状态 retz PVC plastic ceramic core ball valve is a valve that drives the valve core to move through the motor-driven valve stem, which can be divided into shutoff valve and regulating valve. Off means full open or close, with feedback signal; The adjustment can be stabilized in a certain state through time, angle, etc

启闭慢,速度可调,不易产生水锤 Slow opening and closing, adjustable speed, not easy to produce water hammer

直流道,通量大,流阻小 DC channel, high flux, low flow resistance

刮板作用,抗杂质,密封好 Scraper function, anti-impurity, good sealing

电机开关动作到位后即断电The power is cut off after the motor switch acts in place

(有限位开关)电耗小 Low power consumption (limit switch)

防水等级IP65 Waterproof grade IP65

控制接线图 Control wiring diagram

二线断电复位Two-wire power-off reset

1、SW闭合，电动球阀打开，到位后并保持；

2、SW断开，电动球阀关闭，到位后并保持；适用于DC9~24V球阀。

二线断电复位：采用法拉电容原理，功能相当于电磁阀，常开或常闭，断电自动复位。断电复位后再次通电时间不少于15分钟，不宜频繁启闭。

三线断电复位 Three-wire power-off reset

1、SW与红线相连，电动球阀打开，到位后并保持；

2、SW与绿线相连，电动球阀关闭，到位后并保持；适用于DC12V、DC24V球阀。

三线断电复位：控制线为三芯线，同三线控制。正常工作时，法拉电容充电待用，外部发生停/断电时，电容放电使球阀自动复位。

DC电压三线一控 DC voltage three-wire one-control

电源线为三芯线，其中一芯与公共线通时为开，另一芯线与公共线通时为关

Three wires as controlling wire. When one wire connect with public wire, the ball valve open;when another wire connect with public wire,the ball valve close,

1、SW与红线相连，电动球阀打开，到位后并保持；

2、SW与绿线相连，电动球阀关闭，到位后并保持；

适用于DC12V、DC24V球阀。

AC电压三线一控 AC voltage three-wire one-control

1、SW与红线相连，阀门打开，到位后并保持；

2、SW与绿线相连，阀门关闭，到位后并保持；

适用于AC220V阀门。

二线带位置反馈球阀 Two-wire ball valve with position feedback

接线为五芯线（直流电源）：电源控制线为二芯线，反馈信号线为三芯线。

电源控制线接正向电压为开，并提供“开”信号；

电源控制线接反向电压为关，并提供"关"信号；

1、SW与OPEN短接，电动球阀打开，到位后并保持。同时LS.1接通并给出开到位置信号，即BL与WT相通：

2、SW与CLOSE短接，电动球阀关闭，到位后并保持。同时LS.2接通并给出关到位置信号，即YL与WT相通；

适用于DC24V球阀。

三线带位置反馈 Three-wire belt position feedback

1、SW与红线相连，阀门打开，到位后并保持。同时LS.1接通并给出开到位置信号，即蓝线与白线相通；
