    • The present invention relates to a device for distributing two fluids in a constant ratio and regulating the flow of the fluids.
      The device comprises a gate valve (10,20) located between a supply line and a discharge line of one of the fluids; a secondary valve (12) located between a supply line and discharge line of the other fluid, said secondary valve comprising an internal tube (42) provided with at least one lateral orifice (44) enabling the other fluid to enter the tube and leave it through its orifice(s), and a closing element (60) controlled by the displacement of gate (20) of the gate valve to uncover the orifice(s) of the tube to a greater or lesser extend, the passage sections for the two fluids being so varied that the flow ratio of the two fluids is constant.
      Preferred application: distribution of gaseous fuel and a gaseous comburent for feeding burners.
    • 本发明涉及一种设备,用于在一个恒定的比率分配两种流体和调节流体的流动。 该装置包括位于供应管线和流体中的一个的排出管线之间的闸阀(10,20); 位于电源线和所述其它的流体的排出管线之间的次级阀(12),所述包括内部管的次级阀(42)设有至少一个侧面孔(44)使所述其它流体进入管和离开它 通过其孔(一个或多个),并且通过门(20)的位移的闸阀的控制,以在管的孔口露出到更大或更小延伸,通道部分用于两个闭合元件(60) 流体是如此多样做了两种流体的流量比是恒定的。 优选的应用:用于供给燃烧器的气体燃料和气态助燃物的分布。
