什么叫隔离阀?

原文:
隔离阀在真空系统中的作用:   1.开关气路,当阀1和阀4关闭,阀2打开时,机械真空泵Ⅲ对容器I抽真空,气流流经预真空抽气管路;当阀2关闭,阀4打开时,机械泵可单独对扩散泵抽真空;当阀1和阀4同时打开时,扩散泵和机械泵可同时工作,对容器进行抽空,此时气流流经扩散泵。可见,阀门在这种操作中的作用是开关气路,改变气流的流经路线。   2.控制气流大小,调节真空度在图1中,调节阀1的阀盖开启角度,即可调节流经管路的气流量大小;关闭阀2和阀4,通过放气阀3可以给机械泵Ⅲ的入口放成大气;通过放气阀5可以调节容器内的真空度。   3.定量充气,在玻璃阀的柱塞上有个一定体积的小洞,当小洞转向右边和高压气瓶连通时,小洞中就可充满高压气体;当它转向左边和真空容器连通时,就把该体积的高压气体放进容器中去,这样就起到了定量充气的作用。   真空阀门的种类繁多,通常按阀门的职能、结构型式、驱动方式、材料和用途进行分类。

译文:
What is the isolation valve? Isolation valve in the vacuum system: A switch gas valve 1 and valve 4 is closed, valve 2 is open, Ⅲ mechanical vacuum container I vacuum, air flows through the pre-vacuum exhaust pipe; valve 2 closed, the valve 4 is opened, the mechanical pump separate diffusion pump vacuum; when the valve 1 and valve open at the same time, the diffusion pump and mechanical pump can work simultaneously on the container for taking the air flows through the diffusion pump. Visible, the role of the valve in the operation of this gas line switch to change the air flowing through the line. Control the flow size, adjust the degree of vacuum in Figure 1, the control valve 1, valve cover opening angle, you can adjust the gas flow flowing through the pipe size; Close valve 2 and valve 4 through the discharge valve to the mechanical pump the ⅲ entrance put into the atmosphere; through the discharge valve can adjust the degree of vacuum inside the container. Quantitative inflatable certain volume of the small hole on the valve plunger in the glass, when a small hole turned to the right and the high-pressure cylinders connected in the small hole can be filled with high-pressure gas; when it turned to the left and the vacuum container connectivity , put the volume high-pressure gas into the container, so that played the role of quantitative inflated. A wide range of vacuum valves, usually the valve functions, structure type, drive mode, material and purpose of classification.
