    • A drain valve assembly for use with an air bath including an air distribution system and a method of cleansing channels of an air distribution system for a bath vessel. The drain valve assembly is located within an opening in the bath vessel to control the flow of water from the bath vessel to an effluent drain, to control the flow of air and water from the air distribution system to an effluent drain and to maintain a fluid pressure within the air distribution system. The drain valve assembly includes a valve housing for extending between the bath vessel and a fluid waste pipe connected to the effluent drain. The valve housing has an upper opening for positioning proximate the bath vessel and a lower opening for receiving fluid from the air bath distribution system. The drain valve assembly also includes a stopper having first and second vertically aligned plungers. The stopper is secured within the valve housing and is capable of moving relative thereto. When the stopper is in a closed position and the second plunger is positioned below a lower surface of the lower opening, fluid from the air distribution system is sealed within the valve housing and fluid within the bath vessel is prevented from entering the valve housing. Conversely, fluid from the bath vessel and the air distribution system flows through the valve housing and into the fluid waste pipe when the stopper is in an open position and the second plunger is above a lower surface of the lower opening.
    • 一种用于包括空气分配系统的空气浴的排水阀组件,以及用于清洗用于浴槽的空气分配系统的通道的方法。 排水阀组件位于浴槽中的开口内,以控制从浴槽到出水流出物的水流,以控制空气和水从空气分配系统流到流出物排出口并保持流体 空气分配系统内的压力。 排水阀组件包括阀壳体,用于在浴槽和连接到流出物排出口的流体废液管之间延伸。 阀壳体具有用于定位在浴槽附近的上开口和用于从气浴分配系统接收流体的下开口。 排水阀组件还包括具有第一和第二垂直对准的柱塞的止动器。 止动器固定在阀壳体内并且能够相对于其移动。 当止动器处于关闭位置并且第二柱塞位于下开口的下表面下方时,来自空气分配系统的流体被密封在阀壳体内,并且防止了浴槽内的流体进入阀壳体。 相反,当止动器处于打开位置并且第二柱塞在下开口的下表面上方时,来自浴槽和空气分配系统的流体流过阀壳体并进入流体废液管道。
