Abstract

本发明涉及一种隔离环，其由二等分的环1组成，其所有圆周上设置有槽状叶片轮廓2。

Description

隔离环
技术领域
本发明涉及一种隔离环，其用于发电站的涡轮叶轮，其代替由分开的零件装配的组合定子分布轮。
背景技术
迄今，隔离叶片已被生产单独用于单个叶片且安装成一个整体。该部分组合系统具有相当大的缺点，包括装配不准确、介质流量不稳定，该组件装配以需要大劳动量而著称，制造要求特别的机器以生产各个零件，最后但并非最不重要的一点是，生产成本较高，使得装置的价格相当昂贵。
发明内容
上述缺点可被具有下列性质的本发明的隔离环消除：其包括二等分环；其所有圆周上设置有槽状叶片轮廓。
根据该发明设计的隔离环使得其可以被装配具有较高的介质流动的精度，而不存在任何可能流动波动。在装配期间组合整个环所需的劳动量被数倍地减少，导致装配成本数倍地减少。
附图说明
本发明通过详细图示的方式将更清楚，其中
图1是由两个零件组成的隔离环的前视图；
图2是隔离环的横截面。
具体实施方式
根据图1的隔离环包括二等分环1，在其所有圆周上设置有槽状叶片轮廓2。
根据本发明设计的隔离环是设计用于蒸汽动力涡轮机，但可以被用于任意驱动介质，其中要求介质的剂量的高准确度。
