摘要： A valve unit with a level indicator for containers, in particular containers for liquefied gases, comprising; a valve body having external dimensions and an external geometry compatible with filling equipment used for similar valve bodies, without a level indicator, and having a substantially axial gas duct, a piston shutter which may be axially displaced in the valve body to and from a valve seat in order selectively to intercept the gas duct, a control rod of a floating actuator extending into the gas duct and into an axial cavity of the piston, a primary magnet which may be displaced axially in the axial cavity of the piston under the action of the control rod in response to a variation of the level in the container, a level indicator including a moving assembly subject to the magnetic field of the primary magnet in order to display the gas level detected by the floating actuator, the level indicator comprises a housing for the moving assembly which is secured to the valve body independently from the piston shutter.
摘要翻译：具有用于容器的液位指示器的阀单元，特别是用于液化气体的容器，包括：具有外部尺寸的阀体和与用于类似阀体的填充设备相匹配的外部几何形状，没有液位指示器，并且具有基本上轴向的气体管道，可以在阀体中轴向移动到阀体和从阀门轴向移动的活塞闸门座位，以选择性地拦截气体管道，浮动致动器的控制杆延伸到气体管道中并进入活塞的轴向空腔，初级磁体可以在活塞的轴向空腔内轴向移动，所述控制杆响应于所述容器中的液面的变化，液位指示器包括受到所述主磁体的磁场的移动组件，以便显示由所述浮动致动器检测到的气体水平，所述液位指示器包括壳体用于独立于活塞闸门固定到阀体的移动组件。
