所谓蝶阀，也可以称为翻板阀，是一种结构简单的关断阀。它的阀芯为圆盘形的蝶板结构设计，可沿垂直管道轴线的立轴转动，围绕阀轴旋转来达到开启与关闭。

The so-called butterfly valve, also known as a flap valve, is a simple shut-off valve. Its valve core is designed with a disc shaped butterfly plate structure, which can rotate along the vertical axis of the pipeline and rotate around the valve axis to achieve opening and closing.

　　据了解，蝶阀结构简单、体积小、重量轻、耗材少、驱动力矩小，以及操作简单方便，并且还可以同时具有良好的流量调节功能和关闭密封特性，是近十几年来发展非常快的阀门品种之一。

金彩汇It is understood that butterfly valves have a simple structure, small volume, light weight, low consumables, small driving torque, and simple and convenient operation. They can also have good flow regulation function and closing sealing characteristics at the same time, making them one of the rapidly developing valve varieties in the past decade.

金彩汇　　为了更好地满足高低温度、强冲蚀、长寿命等工业用户应用的使用要求，密封蝶阀得到了很大的发展。与此同时，蝶阀的使用的品种和数量目前仍在继续扩大，并向高温、高压、大口径、高密封性、耐腐蚀性强、不易老化、摩擦系数低、长寿命等，以及一阀多功能方向快速发展。据介绍，蝶阀可靠性及其他性能指标均达到较高水平。

金彩汇In order to better meet the usage requirements of industrial users such as high and low temperatures, strong erosion, and long service life, sealed butterfly valves have made great progress. At the same time, the variety and quantity of butterfly valves used are still expanding, and are rapidly developing towards high temperature, high pressure, large diameter, high sealing performance, strong corrosion resistance, low aging resistance, low friction coefficient, long service life, as well as one valve multifunctional direction. It is reported that the reliability and other performance indicators of butterfly valves have reached a high level.
