摘要:
An electrically actuated control valve has three mouths and three operating positions, in which the three mouths includes a first mouth for inlet of a working fluid, and a second mouth and a third mouth for outlet of the working fluid. The three operating positions include a first operating position in which a passage of fluid from the first mouth to the second mouth and the third mouth is enabled, a second operating position in which a passage of fluid from the first mouth to only one of said second and third mouths is enabled, and a third operating position in which the passage of fluid from the first to the second mouth and the third mouth is disabled. The control valve includes an electric or electromagnetic actuator for controlling the passage of fluid from the first mouth to the second and third mouths providing the aforesaid three operating positions.
摘要(中):
电动控制阀具有三个口和三个操作位置,其中三个口包括用于工作流体入口的第一口,以及用于工作流体出口的第二口和第三口。 三个操作位置包括第一操作位置,在该第一操作位置中,流体从第一口到第二口和第三口能够通过;第二操作位置,其中流体从第一口到所述第二口中的一个通过 并且第三口被启用,并且第三操作位置,其中流体从第一口到第二口和第三口的通过被禁用。 控制阀包括电动或电磁致动器,用于控制流体从第一口到达第二和第三口的通道,从而提供上述三个操作位置。
