原文：浮阀floatingvalve，是浮阀塔板上的气相分散构件。可以在塔板上浮动，随着气体流量的变化而改变其开启度。　　浮阀的型式很多，有圆形阀，还有条形的角阀等。中国目前主要采用的是圆形阀。其中最常用的是F1型，国内已有部颁标准(JB1118)。标准规定阀体材料可以选用碳钢、不锈钢或耐酸钢；轻阀厚度为1.5mm，重约25g，重阀厚度为2mm，重约33g。　　浮阀固定在容器壁上的所需高度上，并与供应管道连接。当液面升高时，浮球上升并通过杆臂来关闭阀。当液面下降时，供应管道打开，介质流入，直至再次达到各自的液位高度。　　应用领域：工业水处理、化学加工工业　　实际某些应用领域中，条型浮阀比F1型浮阀更好，理由如下：　　1. 条型浮阀目前已经广泛使用，同类的还有导向浮阀等　　2. 分离效率比较高　　3. 对于用户最实在的优点：与传统浮阀相比较，不容易脱落、不容易卡阻　　4. 处理能力比F1型浮阀高20％以上　　5 .塔板的泄漏、压降、效率与F1型浮阀相当

Overview of the float valve Float valve floatingvalve, the float valve of the gas dispersion plate tower components. Floating in the Tower board, with the gas flow with changes in its opening degree. Many types of float valves have circular valve, as well as strip the angle valve and so on. China is mainly used in a circular valve. One of the most commonly used is F1 type, the country has ministerial standards (JB1118). Standard body material can be carbon steel, stainless steel or acid-resistant steel; light valve thickness of 1.5mm, weighs about 25g, re-valve thickness of 2mm, and weighs about 33g. Float valve fixed on the walls of the required height, and with the supply pipe connection. When the liquid level rises, the float rises and to close the valve by the lever arm. When the liquid level drops, the supply pipeline open, medium flow, level up again to reach their height. Applications: Industrial water treatment, chemical processing industry Practical in some applications, the bar-type float valve float valve better than the F1, the following reasons: 1 of type float valve is now widely used, there are similar float valve guide (2) a relatively high separation efficiency 3 For most users it's advantages: Compared with the traditional float valve, is not easy to fall off, not easy to jam 4 processing power than the F1-type float valve for more than 20% 5 plate leakage, pressure drop, efficiency, and F1-type float valve rather
