Butterfly Valve
蝶阀又叫翻板阀，是一种结构简单的调节阀，可用于低压管道介质的开关控制的蝶阀是指关闭件（阀瓣或蝶板）为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。在管道上主要起切断和节流作用。蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。
Butterfly valve, also known as flip valve, is a simple structure control valve, which can be used for the switch control of low-pressure pipeline media. Butterfly valve refers to a valve whose closing part (disc or butterfly plate) is a disc and rotates around the valve axis to open and close. The valve can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Fluid flow. It mainly plays the role of cutting off and throttling in the pipeline. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating.
2工作原理
2 Working Principle
蝶板由阀杆带动，若转过90°，便能完成一次启闭。改变蝶板的偏转角度，即可控制介质的流量。
The butterfly plate is driven by the valve stem. If the butterfly plate rotates 90 degrees, it can be opened and closed once. The flow rate of medium can be controlled by changing the deflection angle of butterfly plate.
使用工况和介质：蝶阀适用于发生炉、煤气、天然气、液化石油气、城市煤气、冷热空气、化工冶炼和发电环保、建筑给排水等工程系统中输送各种腐蚀性、非腐蚀性流体介质的管道上，用于调节和截断介质的流动。
Working Conditions and Medium: Butterfly valves are suitable for pipelines conveying corrosive and non-corrosive fluid media in the engineering systems of producer, gas, natural gas, liquefied petroleum gas, urban gas, hot and cold air, chemical smelting, power generation, environmental protection, building water supply and drainage, etc., to regulate and cut off the flow of media.
