PB-Ⅰ/PB-Ⅱ平板闸门

PB-Ⅰ/PB-Ⅱ平板闸门是粉料、晶粒料、小颗粒料的流量输送控制的主要设备。广泛适用于冶金、矿山、建材、粮食、化工等行业。PB-Ⅰ平板闸门配备电动、气动、电液动推杆作为驱动装置，是控制流量大小，切断迅速的设备。
Flat valve is a main equipment to control and convey powder material, crystal material and small grain material.
It is widely used in metallurgical, ore, building material，foodstuff and chemical industry etc. The valve has motorized, pneumatic and motorized and hydraulic handspike as driving device. It is an ideal equipment to control flow and quick cutting.

结构特点：
        PB-Ⅰ/PB-Ⅱ平板闸门具有结构简单，操作自如，密封性能优良，局部阻力损失小，切断快，维护保养方便，不易变形等特点。
Structure features
        It is characterized by simple structure, free operation, excellent sealing, small resistance, quick cutting and convenient maintenance and not easy to deform etc.

工作原理：
　　平板闸门主要由执行机构、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，转动行程开关停止，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）。
 

Work principle
        Flat valve is mainly composed of actuator, valve body, inserting plate, sealing device and travel switch etc. When driving, output instructions(power or gas source) to actuator. Actuator drive inserting plate outside and meet work condition. Otherwise close inserting valve (inside toward).
