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。

蝶阀是用圆盘式启闭件往复回转90°左右来开启、关闭或调节介质流量的一种阀门。蝶阀不仅结构简单、体积小、重量轻、材料耗用省、安装尺寸小、驱动力矩小、操作简便、迅速，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，是近十几年来发展的阀门品种之一。蝶阀的使用非常广泛。其使用的品种和数量仍在继续扩大，并向高温、高压、大口径、高密封性、长寿命、优良的调节特性，以及一阀多功能发展。其可靠性及其他性能指标均达到较高水平。

随着防化学腐蚀的合成橡胶在蝶阀上的应用，蝶阀的性能得以提高。由于合成橡胶具有耐腐蚀、抗冲蚀、尺寸稳定、回弹性好、易于成形、成本低廉等特点，并可以根据不同的使用要求选择不同性能的合成橡胶，以满足蝶阀的使用工况条件。

The butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast to operate, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties. The use of butterfly valves is very extensive. The variety and quantity of its use continues to expand, and is developing towards high temperature, high pressure, large diameter, high sealing performance, long life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.

With the application of chemically resistant synthetic rubber to the butterfly valve, the performance of the butterfly valve can be improved. Because synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, easy forming, low cost, etc., synthetic rubber with different properties can be selected according to different usage requirements to meet the operating conditions of the butterfly valve.
