球阀分有：浮动式球阀、固定式球阀、轨道球阀、V型球阀、三通球阀、不锈钢球阀、铸钢球阀、锻钢球阀、卸灰球阀、抗硫球阀、气动球阀、电动球阀、卡套球阀、焊接球阀。
Ball valves are divided into floating ball valves, fixed ball valves, track ball valves, V-shaped ball valves, three-way ball valves, stainless steel ball valves, cast steel ball valves, forged steel ball valves, ash discharge ball valves, sulfur resistant ball valves, pneumatic ball valves, electric ball valves, sleeve ball valves, and welded ball valves.
按壳体/主体材料分类，球阀可分为：
According to the classification of shell/main material, ball valves can be divided into:
1. 金属材料阀门：如碳钢阀门、合金钢阀门、不锈钢阀门、铸铁阀门、钛合金阀门、蒙乃尔阀门、铜合金阀门、铝合金阀门、铅合金阀门等。
1. Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, etc.
2. 金属阀体衬里阀门：如衬胶阀门、衬氟阀门、衬铅阀门、衬塑阀门、衬搪瓷阀门。
2. Metal valve body lined valves: such as rubber lined valves, fluorine lined valves, lead lined valves, plastic lined valves, and enamel lined valves.
3. 非金属材料阀门：如陶瓷阀门、玻璃阀门、塑料阀门。
3. Non metallic material valves: such as ceramic valves, glass valves, plastic valves.
国内生产球阀的厂家比较多，连接尺寸也大多不统一。主要分以下几个大类：
There are many domestic manufacturers of ball valves, and most of them have inconsistent connection sizes. Mainly divided into the following categories:
球阀的球体是浮动的，在介质压力作用下，球体能产生一定的位移并紧压在出口端的密封面上，保证出口端密封。
The ball of a ball valve is floating, and under the pressure of the medium, the ball can produce a certain displacement and tightly press on the sealing surface of the outlet end, ensuring the sealing of the outlet end.
