<span>插板门是输送飞灰和粉状干物料的系统中用它截止输送物的装置，可安装在火力发电厂的省煤器、空气预热器、干式除尘器、烟道等灰斗下部，也可与电动给料机配套使用，工作温度允许达</span>200℃<span>。这种装置重量轻、体积小、无飞灰外跑。</span>

<b><span>工作原理</span></b><br>
<span>风门运行需关闭时</span>,<span>按关门按钮</span><span>,</span><span>电机受电驱动</span><span>,</span><span>经减速机后</span><span>,</span><span>带动主轴齿轮回转</span><span>,</span><span>通过齿轮传动使行走方钢齿条产生位移</span><span>,</span><span>从而带动门板行走。门板关闭时进入内框架门槽里</span><span>,</span><span>使风道介质隔断</span><span>,</span><span>由于门板平面四周镶有密封条</span><span>,</span><span>所以风门关闭后使介质不能泄露到门的另一面。</span><br>
<span>风门需开启时</span>,<span>按开门按钮</span><span>,</span><span>门板进入外框架门槽里</span><span>,</span><span>由于外框架是全封闭的</span><span>,</span><span>所以当门板开启时介质是不会外泄露的。</span><br>
<span>风门的启闭到位是靠执行器内部行程开关控制停止的</span>,<span>所以门的启闭到位行程只要调整执行器内部控制系统即可</span>
