功能介紹 Function introduction

PVC塑料陶瓷芯球閥是通過電機驅動閥桿帶動閥芯動作的閥門，可分為關斷和調節閥。關斷即全開或關閉，可帶反饋信號；調節可以通過時間、角度等方式穩定在某種狀態 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

啟閉慢,速度可調,不易產生水錘 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,抗雜質,密封好 Scraper function, anti-impurity, good sealing

電機開關動作到位后即斷電The power is cut off after the motor switch acts in place

(有限位開關)電耗小 Low power consumption (limit switch)

防水等級IP65 Waterproof grade IP65

二線斷電復位Two-wire power-off reset

1、SW閉合，電動球閥打開，到位后并保持；

2、SW斷開，電動球閥關閉，到位后并保持；適用于DC9~24V球閥。

二線斷電復位：采用法拉電容原理，功能相當于電磁閥，常開或常閉，斷電自動復位。斷電復位后再次通電時間不少于15分鐘，不宜頻繁啟閉。

三線斷電復位 Three-wire power-off reset

1、SW與紅線相連，電動球閥打開，到位后并保持；

2、SW與綠線相連，電動球閥關閉，到位后并保持；適用于DC12V、DC24V球閥。

三線斷電復位：控制線為三芯線，同三線控制。正常工作時，法拉電容充電待用，外部發生停/斷電時，電容放電使球閥自動復位。

DC電壓三線一控 DC voltage three-wire one-control

電源線為三芯線，其中一芯與公共線通時為開，另一芯線與公共線通時為關

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與紅線相連，電動球閥打開，到位后并保持；

2、SW與綠線相連，電動球閥關閉，到位后并保持；

適用于DC12V、DC24V球閥。
