众多的小型蓄水工程是山丘区拦蓄洪水、发展灌溉、渔业生产的主要工程设施 ,而输水闸门又是蓄水枢纽工程的重要组成部分 ,它的操作性能 ,直接影响工程效益的发挥。针对传统的输水闸门在运行管理中易出现漏水、闭锁、错位、管理不便等问题 ,研制出一种新型水工闸门球体闸门。1　 Numerous small-scale water-storage projects are the main engineering facilities for flood control in mountainous areas and the development of irrigation and fishery production. The water-sluice gate is also an important part of the water-storage project. Its operational performance directly affects the performance of the project. In view of the problems that water leakage, blocking, dislocation and inconvenient management are easy to occur in the operation and management of the traditional water gate, a new type of hydraulic gate gate is developed. 1
