This paper mainly introduces the types of large diameter ball valve and its application, and I PN1.0 subject DN500 large-diameter gas valve, the valve type two sections of large diameter ball side. This valve USES casting process. Body structure using two stages, through the bolt connection, Sphere for top connections, sphere proves, bottom valve stem with support bar and body support fixed. Stem from a tight seal of the half - type of valve stem and packing seal, a body structure, anti-static supported by sliding bearing bar to reduce friction, Seat with a seat, nonmetal material is PTFE, Seat with temporary sealing function of emergency oil hole, The body has relinef-pressure devince, when the pressure to achieve work pressure, 1.33 will automatically.
Based on a series of calculation of the ball. Introduces the body wall thickness, the calculation of fixed ball valve sealing two-way stem torque and intensity, double check valve seal fixed ball valve seal two-way surface total force and calculation of pressure, seat sealing ball of friction torque, the calculation of inlet seat sealing ball of friction torque, the calculation of inlet seat sealing the sphere of friction torque, outlet seat sealing sphere of friction torque, the calculation of the seat sealing ball bearing, friction torque friction torque, thrust pad of friction torque, with stem packing friction torque and between O ring and the friction between the stem seal fixed ball valve, two-way stem torque, stem strength calculation. In the design of the software used SolidWorks ball in normal working conditions are main structure and hydrostatic test pressure, the pressure seal test three under pressure of displacement and stress analysis.

普通不锈钢球阀和高温球阀有什么区别？
一、高温球阀和常温球阀的主要区别制造工艺不同，二、密封方面区别：一般常温球阀是软密封阀座；高温是硬密封(金属或机械碳还有陶瓷等），而且阀内件材质比软密封的要好，三、材料处理方面：一般常温球阀车床加工完以后就可以直接进入装配；高温球阀还要经过处理（因为不同材质处理的工艺也不一样，比如渗氮、喷涂等等，这里就不详细说了）四、组装：一般常温球阀拿到零件后可以至接组装；高温球阀需要研磨球芯和阀座，这道序也很关键，泄漏量的大小就靠研磨了.
