摘要： A filler coupling comprising an isolation valve that can move relative to a seat between an upstream closing position and a downstream opening position, said isolation valve being moved to its upstream position by a return member, the coupling also comprising a dust-prevention valve placed upstream of the isolation valve, said dust-prevention valve comprising a downstream end and being able to move relative to the body between an upstream closing position and a downstream opening position, said dust-prevention valve being moved to its upstream position by a return member, characterized in that the dust-prevention valve can be moved selectively downstream either: in a first determined downstream position opening the upstream end in which the downstream end of the dust-prevention valve does not push the upstream end of the isolation valve, or in a second determined downstream position opening the upstream end, in which the downstream end of the dust-prevention valve pushes an upstream end of the movable isolation valve in order to move the isolation valve by contact to its downstream open position, and in that the dust-prevention valve comprises one or more passageways for guiding at least a portion of the fluid stream traveling from upstream to downstream through the body of said dust-prevention valve.

摘要翻译： 一种填料联接器，包括隔离阀，所述隔离阀能够相对于座椅在上游关闭位置和下游打开位置之间移动，所述隔离阀通过返回构件移动到其上游位置，所述联接器还包括放置在上游的防尘阀 所述防尘阀包括下游端并且能够在上游关闭位置和下游打开位置之间相对于主体移动，所述防尘阀通过返回构件移动到其上游位置， 其特征在于，防尘阀可以选择性地向下游移动：在第一确定的下游位置，打开防尘阀的下游端不推动隔离阀的上游端的上游端，或者在 第二确定的下游位置打开上游端，其中防尘阀的下游端推动上游 d，以便通过接触将隔离阀移动到其下游打开位置，并且防尘阀包括一个或多个通道，用于引导从上游到下游行进的至少一部分流体流 所述防尘阀体。
