進(jìn)口真空球閥
德國(guó)泰科閥門（）有限公司—廣州總代理
進(jìn)口高真空球閥是在真空系統(tǒng)中用來(lái)開(kāi)啟或隔斷氣流的閥門，廣泛適用各類氣體，液體等正、負(fù)壓力管道系統(tǒng)，符合GMP標(biāo)準(zhǔn),由于球閥全通導(dǎo)，又能達(dá)到超高真空要求，所以也能適用于加速器真空系統(tǒng)。
進(jìn)口高真空球閥作用：
1.開(kāi)關(guān)氣路，當(dāng)閥1和閥4關(guān)閉，閥2打開(kāi)時(shí)，機(jī)械真空泵Ⅲ對(duì)容器I抽真空，氣流流經(jīng)預(yù)真空抽氣管路；當(dāng)閥2關(guān)閉，閥4打開(kāi)時(shí)，機(jī)械泵可單獨(dú)對(duì)擴(kuò)散泵抽真空；當(dāng)閥1和閥4同時(shí)打開(kāi)時(shí)，擴(kuò)散泵和機(jī)械泵可同時(shí)工作，對(duì)容器進(jìn)行抽空，此時(shí)氣流流經(jīng)擴(kuò)散泵。可見(jiàn)，閥門在這種操作中的作用是開(kāi)關(guān)氣路，改變氣流的流經(jīng)路線。
2.控制氣流大小，調(diào)節(jié)真空度在圖1中，調(diào)節(jié)閥1的閥蓋開(kāi)啟角度，即可調(diào)節(jié)流經(jīng)管路的氣流量大?。魂P(guān)閉閥2和閥4，通過(guò)放氣閥3可以給機(jī)械泵Ⅲ的入口放成大氣；通過(guò)放氣閥5可以調(diào)節(jié)容器內(nèi)的真空度。
3.定量充氣，在玻璃閥的柱塞上有個(gè)一定體積的小洞，當(dāng)小洞轉(zhuǎn)向右邊和高壓氣瓶連通時(shí)，小洞中就可充滿高壓氣體；當(dāng)它轉(zhuǎn)向左邊和真空容器連通時(shí)，就把該體積的高壓氣體放進(jìn)容器中去，這樣就起到了定量充氣的作用。

Imported high vacuum valve is used in the vacuum system valves open or cut off air flow, widely used types of gases, liquids and other positive and negative pressure piping systems, in line with GMP standards, as all-pass valve guide, while maintaining ultra-high vacuum requirements , so it can be applied to the accelerator vacuum system.
Imported high vacuum valve function:
1 switch gas when the valve 1 and valve 4 is closed, valve 2 is opened, the container I Ⅲ mechanical vacuum pump vacuum, air flows through the pre-vacuum suction piping; when the valve 2 closed and valve 4 is opened, the mechanical pump separate diffusion pump vacuum; when the valve 1 and valve 4 is opened, the diffusion pump and mechanical pump can work simultaneously on the container for taking the time, air flows through the diffusion pump. Visible, the valve's role in this operation is to switch gas, change the air flow through the line.
(2) control the airflow, vacuum regulator in Figure 1, the control valve 1, the valve cover opening angle can adjust the size of the gas flow through the pipeline; shut off valve 2 and the valve 4, through the discharge valve 3 can be a mechanical pump discharge into the atmosphere inlet ⅲ; 5 can be adjusted through the discharge valve of vacuum within the container.
3 Quantitative inflated, the glass on the plunger has a certain volume of the hole, when the hole to the right and high pressure gas cylinders connected, the holes can be filled in high pressure gas; when it is turned to the left and the vacuum vessel is communicated , put the volume of high-pressure gas into the container to go, so that played the role of a quantitative inflation.
