概述

钟罩阀是重要用于高温尘气的开关阀，高炉和煤气发生炉使用比较常见，有干式和湿式两种类型。具有结构紧凑，占地面积小，气密性严，可靠性高等特点。钟罩阀原理很简单，上部是一筒状或者锥形钟罩，钟罩与上部运动杆相连，下部为进气口，密封时钟罩着落将下部进气口密封，反之向上则阀门开启，出口设置在侧面。

工作原理

A：环链葫芦型chain hoist

钟罩阀主要由阀座、钟罩、阀体、阀盖、提升吊杆、提升架及吊杆润滑密封系统、环链电动葫芦和爬梯系统组成。钟罩与阀座为铸钢件，控制钟罩与阀座的相对位置关系就能达到控制流体流量的目的。工作时，阀座是安装在管道上不动的。钟罩经吊杆，穿过润滑密封系统与环链电动葫芦的吊钩连接成一体。当环链电动葫芦得到动作信号，开启钟罩阀时，环链电动葫芦拉起吊钩，吊杆垂直上升，从而将钟罩提升，这样就使钟罩与阀座产生了距离，钟罩阀两端的管路就连通了，实现烟气的排放。反之，环链电动葫芦吊钩下降，钟罩在重力的作用下落下，直到接触到阀座，这样就将管路两端的烟气截断了。
Bell valve is mainly composed of valve seat, bell, valve body, valve cover, lifting boom, poppet and derrick lubrication sealing system, chain electric hoist and the ladder system. Bell bell and seat for steel casting, control the relative position of relationship with the valve seat can achieve the goal of controlling fluid flow. At work, the seat is installed on the pipeline. Bell after the boom, through the lubrication and sealing system chain electric hoist crane connection into a whole. When get action signal chain electric hoist, when you start the bell valves, chain electric hoist pull hook, derrick vertical rise, thus to raise its bell, thus make bell jar and seat produced distance, bell valves at the ends of the line is connected, realize the flue gas emissions. On the other hand, the link chain electric hoist hook down, bell under gravity whereabouts, until the access to the seat, so it will be at the ends of the pipeline gas cutting.

叠：卷扬机型奥颈苍诲濒补蝉蝉：

当卷扬机得到动作信号，开启钟罩阀时，卷扬机拉紧钢丝绳，吊杆垂直上升，从而将钟罩提升，这样就使钟罩与阀座产生了距离，钟罩阀两端的管路就连通了，实现烟气的排放。反之，卷扬机松开钢丝绳，钟罩在重力的作用下落下，直到接触到阀座，这样就将管路两端的烟气截断了。
When the hoist to get action signal, when you start the bell valves, hoist taut wire rope, derrick vertical rise, thus to raise its bell, thus make bell jar and seat produced distance, bell valves at the ends of the line is connected, realize the flue gas emissions. On the other hand, the release of wire rope hoist, bell under the gravity whereabouts, until the access to the seat, so it will be at the ends of the pipeline gas cutting.
