蝶阀有弹密封和金属的密封两种密封型式
硬密封蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该电动阀门具有良好的流体控制特性。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。蝶阀有弹密封和金属的密封两种密封型式。弹性密封阀门，密封圈可以镶嵌在阀体上或附在蝶板周边。
Hard seal butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be opened and closed quickly with only 90 ° rotation, and the operation is simple. At the same time, the electric valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valve has two types of seal: elastic seal and metal seal. Elastic sealing valve, sealing ring can be inlaid on the valve body or attached to the periphery of butterfly plate.
如果要求蝶阀作为流量控制使用，主要的是正确选择阀门的尺寸和类型。硬密封蝶阀的结构原理尤其适合制作大口径阀门。硬密封蝶阀不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用，而且还应用于热电站的冷却水系统。
If butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of valve. The structure and principle of hard seal butterfly valve is especially suitable for making large diameter valve. Hard seal butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in cooling water system of thermal power station.
