球阀和蝶阀都是比较常用的阀门。有些场合是可以通用的，而有些工况又是只能用其中的一种的。两者的区别主要在于结构和开关原理。我们简要分析：球阀：旋塞阀演变而来，启闭件是球体。特点是：1、低流阻；2、较大的压力和较高温度下，可实现完全密封；3、可快速启闭；4、其密封结构决定其比较设和腐蚀性接孩子；5、阀体对称，可以有效承受管道压力，可应付高压工况；蝶阀：启闭件是圆盘式左右开启，特点是：1、结构简单、体积小、安装方便；2、流阻系数小，启闭迅速，；3、可用于大口径阀门；4、可应用不同的密封面，使用各种环境，包括粉状、颗粒状介质等；蝶阀相对于球阀，密封性稍差，但大口径阀门中，蝶阀比球阀要具有得天独厚的优势；当做调节流量用时，蝶阀调节范围不大，而V型调节球阀，调节精确。另外，在高压管路中，球阀要比蝶阀具有优势。

Appropriate choice of ball and butterfly valves Ball and butterfly valves are commonly used. Some situations can be common, and some conditions is only one kind of use. The main difference between the structure and switching principle. Our brief analysis: Ball Valves: Plug Valves evolved, opening and closing pieces is a sphere. Features: 1, low flow resistance; 2, greater pressure and higher temperatures, can be completely sealed; 3, can quickly open and close; 4, the sealing structure is located and to determine their more aggressive pick up their kids; 5, body symmetry, can effectively withstand the pressure of the pipeline, can cope with high-pressure conditions; Butterfly: open and close around disc piece is open, is characterized by: 1, simple structure, small size, easy installation; 2, flow resistance coefficient is small, open and close quickly; 3, can be used for large diameter valves; 4. can be applied to different sealing surface, using a variety of environments, including powder, granular media, etc.; Relative to the butterfly valve, sealing a bit weak, but the large-diameter valve, butterfly valve than to have a unique advantage; when used as a flow regulator, valve adjustment range is not, and V-ball valve, precise adjustment. In addition, the high-pressure pipe, ball valve than an advantage.
