一、 用途:
本系列阀适用于电厂、石油、化工、冶金、矿山、建材等水、油品、蒸汽及与阀门材质许用的腐蚀与非腐蚀性介质的水平或垂直管路。
二、 主要业绩:
韩国大宇等
三、 结构特点:
1) 浮动式球阀采用双斜面弹性密封圈或V型槽弹性密封圈结构设计,保证密封的可靠性,对于低压、超低压或真空工况用球阀,采用板簧加载的阀座密封结构,能确保球阀长期可靠的密封。中、高温球阀的阀座材料可选用对位聚苯或金属材料。
固定式球阀根据压力大小、介质性质及密封要求的不同而选择球阀密封结构、球后密封结构或球前球后双密封结构。
2) 当中腔压力出现异常升高现象时,中腔介质能依靠本身的推力推动阀座而自动泄压,从而确保阀体的安全;
3) 阀杆采用有倒密封的下装式结构,倒密封的密封力随介质压力的增高而增大,故能确保阀杆的可靠密封,而且,当阀腔异常升高时,阀杆不会喷出。
4) 两端采用法兰连接。
