Zusammenfassung: | The utility model discloses a hydraulic system and a ball valve of a mixed-flow water turbine, and relates to the technical field. The device comprises a water supply unit, a tail water unit and a valve body unit. The ball valve hydraulic system has the advantages that liquid of a power source for overhauling sealing and working sealing in the ball valve hydraulic system is changed into water from oil, so that the problem that oil is mixed with water due to the fact that an original sealing position is abraded and leaks water can be solved, and the oil consumption of the ball valve system is reduced; in addition, according to the water flow direction and the position relation between the overhauling seal and the working seal, different kinds of electromagnetic valves are reasonably selected, and orderly switching of the overhauling seal and the working seal is achieved.
本实用新型公开了一种液压系统及混流式水轮机球阀,涉及技术领域。本实用新型包括供水单元、尾水单元和阀体单元。本实用新型的有益效果:本申请将球阀液压系统中检修密封、工作密封的动力源的"液"由油改为水,这样就可以解决原有密封处磨损漏水导致的"油混水"问题,且减少了球阀系统的用油量;此外, |
