摘要:
A vacuum demand valve (10) is capable of delivering a flowable material. The valve (10) has a housing (11) having a proximal end (14), a distal end (16), an intermediate segment (18) therebetween defining a passageway (24) wherein the flowable substance can flow from the proximal end (14) to the distal end (16). The housing (11) can be tubing. A valve member (20) is located along the intermediate segment (18). The valve member (20) has a closed condition wherein the flowable material from the proximal end (14) to the distal end (16) is stopped and an open condition wherein the flow of the flowable material from the proximal end (14) to the distal end (16) is unstopped. The valve member (20) is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway (24) for placing the valve member (20) in the open condition.
摘要(中):
真空需求阀(10)能够输送可流动的材料。 阀(10)具有壳体(11),其具有近端(14),远端(16),间隔开的中间段(18),限定通道(24),其中可流动物质可以从近端( 14)到远端(16)。 外壳(11)可以是管道。 阀构件(20)沿着中间段(18)定位。 阀构件(20)具有闭合状态,其中从近端(14)到远端(16)的可流动材料停止,并且打开状态,其中可流动材料从近端(14)流到 远端(16)不受阻挡。 阀构件(20)在关闭状态下被偏压并且响应于用户通过通道(24)提供的用于将阀构件(20)置于打开状态的部分真空。
