直角锥阀 弹性体密封座阀，高真空 美国A＆N公司

弹性体密封座阀，高真空服务，因此设计。 Poppet valves are produced in three body styles: 90° Angle, In-Line, and Angle In-Line.座阀生产的三种车身样式：90°角，线，角的线。 Port terminations are available in ISO-LF/QF, CF, and Tube Ends.可在ISO-LF/QF，CF接口端，管的两端。 Principles of Operation & Construction: Poppet valves are made up of a body, actuator and internal poppet.操作与建设的原则：座阀是由一个机构，执行机构和内部阀芯。 The （manual or pneumatic） actuator transports the poppet linearly. （手动或气动）执行器传输线的阀芯。 When the poppet is moved toward the top of the valve the internal body cavity is open to the system and flow is unimpeded （maximum conductance）.当提升阀移向阀顶部的内部的体腔是开放系统和流量是畅通的（zui大电导）。 Once the actuator moves the poppet to the bottom of the valve an elastomer sealing ring is compressed onto the sealing surface of the lower body of the valve.一旦致动器移动的底部的阀的提升阀的弹性体密封环被压缩到下部主体的阀的密封表面。 This action creates a vacuum tight seal and stops the flow.此操作将创建一个真空密封，并停止流动。
