阀门控制器

　　一、阀门控制器概 述 Brief introduction

　　该系列电动阀门控制箱，是与我厂生产的ZW型、JQ 型及QW 型阀门电动装置配套使用的电控箱，用于控制阀门的开启和关闭，可用于现场单独控制或远方集中控制。 KFD型电控箱有抽屉式和挂壁式两种结构。

　　This series of control cabinet of electric valve is the one to be used together with ZW type, JQ type and QW type electric valve actuator produced by our company and to control the opening and closing of valve. It can be used in site individual control or long-distance centralized control.

　　KFD type electric control cabinet has two kinds of structure: drawer type and wall type. Designation

　　三、阀门控制器安装与调试 Installation and debugging

　　1、将控制箱固定在支架上。

　　2、对照控制箱电气原理图、端子接线图，用电缆按对应的线号把控制箱和电动装置的端子连接起来。

　　3、把三相电源分别接到控制箱的L1、L2;L3、N端子上。

　　4、在阀门处于中间位置时，按“开”或“关”按钮，检查阀门的旋向是否与按钮一致，如不一致则调换电机电源相序。

　　5、在阀“开”“闭”过程中，检查开度表指针是否正常。

　　6、当阀门处于“全开”位置时，检查开度表指针是否指示在满刻度，如有误差，调整面板上的“开度微调”电位器。

　　7、与阀门电动装置配套控制，详见阀门电动装置说明书。

　　1. Fix the control cabinet on the bracket.

　　2. Connect the terminals on the control cabinet with those of the electric actuator by the cable as perelectric schematic diagram and terminal wiring diagram of control cabinet.

　　3. Connect the three-phase power with L1, L2; L3, N terminal on the control cabinet.

　　4. When the valve is in the middle, press on the ON or OFF button to inspect whether the rotationdirection of valve accords with the button. If not, please exchange the phase sequence of power of the motor.

　　5. In the opening and closing course of valve, inspect whether the needle of opening degree meter isnormal.

　　6. When the valve is totally open, inspect whether the needle of opening degree meter indicates to thelimit scale. If there is error, adjust the potentiometer of “fine adjustment of opening degree” on the panel.

　　7. For the details for control of electric valve actuator, please see the operation instructions of electricvalve actuator.
