6、闸)。另一路油,在梭阀 2025 作用下,压力油 P 口通过组合阀 2023 与 G 口导通,G 口油经过危急保安装置到 E1 口，压力油从 E1 口再过组合阀 2011 与 E2 口导通,建立速关油 E2。当速关油 E2 达到 6.5bar 以上时，使电磁阀1839失电，则启动油 与回油 T 口接通。因为换向阀 1839 回油口装有节流孔板，启动油回油缓慢，逐渐打开速关 阀。 注意： .启动之前应确认 DG40插装阀上腔有压力油(见就地压力表 P12、P13)。 .速关阀开启后，启动油 F 应为零。 3.2 速关阀在线试验 当速关阀打开后，操作手动阀 2309 的手柄，使 H1 或 H2 与
7、压力油 P 导通，对速关 阀进行在线试验。停止试验，只需释放手柄即可。因为有节流孔板，速关阀部分位移和复位 动作缓慢，不会出现速关阀关闭现象。 因为手动阀 2309 是三位四通结构，因此可以分别对两个速关阀进行在线试验，作 另一个速关阀试验时，只需将手动阀 2309 的操作手柄往相反动作即可。 3.3 遥控停机 当需要遥控关闭速关阀时,只要使电磁阀 2222、 2223 同时带电,使插装阀DG40 上腔 失压, 这时弹簧力的作用, 插装阀 DG40 开启,速关油 E2 与回油导通, 速关油迅速泄掉,使 速关阀关闭。 3.4 就地停机 当需要就地关闭速关阀时，打开手动阀 2250 上的保险挡块，
8、向前按动手柄，手动 阀2250的A口与回油T口导通， 使插装阀DG40上腔失压, 这时弹簧力的作用, 插装阀DG40 开启,速关油 E2 与回油导通, 速关油迅速泄掉,使速关阀关闭。手动停机阀 2250 动作原理 与停机电磁阀基本相同。速关组合件 操作规范 7/18 3.5 危急保安器在线试验 操作手动阀 2070，使 P 口与 B 口导通，在该压力油作用下，压力油 P 经过组合阀 2023,2033 与速关油 E2 导通,同时, 插装阀 2011 关闭,E1 与 E2 油路被切断。然后, 另一手 旋转手动阀 2080 的下手柄（注：此时不能释放手动阀 2070 的操作手柄）,使 P 口与 B
9、 口导 通，建立试验油 H，进行危急遮断器在线试验。 试验完毕后, 将手动阀 2080 下手柄旋回至初始状态。 然后再操作手动阀 2080 另一端 上手柄（注：此时仍不能释放手动阀 2070 的操作手柄）, 使 P 口 A 口导通，通过换向阀 1830重新建立开关油M,使危急保安装置重新挂闸,G口与E1口导通,最后,依次操作手动阀 2070,2080 回复到原始状态,试验结束。 3.6 原理图 速关组合件 原理图 8/18 速关组合件 维护指南 9/18 4.维护指南 4.1 在汽轮机正常运行时，必须将手动停机阀 2250 的保险装置放到位。以免出现不必 要的停机事故。 4.2 必须在油质检验
