在龙潭水电站球形阀设计中,采用了活塞式双密封、密封环位置显示装置、钢背复合材料轴瓦、带金属软管的接力器、油操作密封环、取消旁通阀管路等结构。这些新结构的使用,使成套球形阀的总体布局更加合理,性能更先进,既节约了材料,减少了制造工时,又为用户运行和检修提供了方便,同时也提高了球形阀的技术经济指标。
In the design of the spherical valve of Longtan Hydropower Station, the piston double seal, the seal ring position display device, the steel back composite material bearing bush, the relay with metal hose, the oil operation seal ring and the bypass valve pipeline are eliminated. The use of these new structures makes the overall layout of the ball valve set more reasonable and the performance is more advanced. This not only saves materials and reduces manufacturing man-hours, but also provides convenience for user operation and maintenance as well as technical and economic indicators of the ball valve .
