    • A flow regulation vent includes a fixed portion adapted to engage a gas supply conduit and a spring force biased movable portion connected by a hinge to the fixed portion and flowingly connected to the pressurized gas supply. The fixed portion includes a gas flow orifice. The movable portion is pivotally movable between 1) a relaxed position, whereby at a specified minimum operating pressure, the movable portion is pivoted by the spring force away from the fixed portion to a position to establish a first gas washout flow area between the movable portion and the gas flow orifice; and 2) a fully pressurized position, whereby at a specified maximum operating pressure, the pressurized gas offsets the spring force to pivot the movable portion to a position adjacent the fixed portion to establish a minimum gas washout flow area between the movable portion and the gas flow orifice.
    • 流量调节通风口包括适于接合气体供应管道的固定部分和通过铰链连接到固定部分并且流体连接到加压气体供应的弹簧力偏置可动部分。 固定部分包括气流孔。 可移动部分可在1)松弛位置之间枢转运动,由此在特定的最小操作压力下,可动部分由弹簧力从固定部分枢转到一个位置,以在可移动部分之间建立第一气体冲洗流动区域 和气流孔口; 和2)完全加压的位置,由此在规定的最大工作压力下,加压气体抵消弹簧力以将可移动部分枢转到邻近固定部分的位置,以在可移动部分和气体之间建立最小气体冲洗流动区域 流量孔。
