 工作原理

Working principle:

  双驱动平板阀主要由执行机构、阀体、插板、密封装置、行程开关等部件组成。运行时输出指令（电源或气源）给执行机构，由执行机构带动插板向外推出，达到工况需要位置，撞动行程开关停止，由行程开关反馈信号（开关信号）给控制室。反之则关闭插板阀（向内推进）。

  The valve is mainly made up of actuator, body, disc, seal device and journey switch etc. Instruction is transmitted to the actuator. The actuator drives disc draw out to reach the requiring position and then bumps the journey switch to stop. Journey switch feeds back the signal to control room. Otherwise close disc.

使用说明：

Operation instruction:

l  本阀可水平或垂直安装，安装时两法兰连接中间必须加密封垫片，然后均匀锁紧螺栓。

l  手动操作时向外抽出为开，向内推进为关。不得在把手上增加辅助器材。

l  执行机构应按其使用说明正确接线与操作。

l  若长期存放应使设备处于关闭状态，各传动部位应加润滑油，不允许露天存放或堆置。

l   The valve can be installed in horizontal or vertical. Add seal cushion between two flanges connection and screw down bolt.

l   Draw out handle means open and push in means close. Assistant lever can’t be added to handle.

l   Actuator must be connected and operated exactly according to the operation instruction.

l   Add lubricant to transmission part when valve is long stored. It should not be placed or piled up in the open air.
