進口真空球閥
德國托普進口真空球閥產品作用：
1.開關氣路，當閥1和閥4關閉，閥2打開時，機械真空泵Ⅲ對容器I抽真空，氣流流經預真空抽氣管路；當閥2關閉，閥4打開時，機械泵可單獨對擴散泵抽真空；當閥1和閥4同時打開時，擴散泵和機械泵可同時工作，對容器進行抽空，此時氣流流經擴散泵?？梢姡y門在這種操作中的作用是開關氣路，改變氣流的流經路線。
2.控制氣流大小，調節(jié)真空度在圖1中，調節(jié)閥1的閥蓋開啟角度，即可調節(jié)流經管路的氣流量大??；關閉閥2和閥4，通過放氣閥3可以給機械泵Ⅲ的入口放成大氣；通過放氣閥5可以調節(jié)容器內的真空度。
3.定量充氣，在玻璃閥的柱塞上有個一定體積的小洞，當小洞轉向右邊和高壓氣瓶連通時，小洞中就可充滿高壓氣體；當它轉向左邊和真空容器連通時，就把該體積的高壓氣體放進容器中去，這樣就起到了定量充氣的作用。
4.真空閥門的種類繁多，通常按閥門的職能、結構型式、驅動方式、材料和用途進行分類。
進口真空球閥產品優(yōu)點:

Imported vacuum ball valve
Germany top vacuum valve products:
1 switch gas, when the valve 1 and valve 4 is closed, the valve 2 is opened, the mechanical vacuum pump on I vacuum container, air flows through the pre vacuum suction pipe; when the valve 2 is closed, the valve 4 is opened, the mechanical pump can separate diffusion pump vacuum; when the valve 1 and valve 4 is opened at the same time when the diffusion pump and mechanical pump can work at the same time, the container to be evacuated, the air flows through the diffusion pump. Visible, the role of the valve in this operation is to switch the gas path, change the flow path of air flow.
2 the size of the air flow control, vacuum regulator in Figure 1, the control valve 1, the valve cover opening angle can adjust the gas flow through the pipeline; close the valve 2 and valve 4, through the discharge valve 3 to the mechanical pump entrance III put into the atmosphere; through the discharge valve 5 can adjust the vacuum container degree.
3 quantitative inflation, have a certain volume of the hole in the glass on the plunger, when the hole to the right and the high-pressure gas cylinders connected, the holes can be filled with 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, this kind of play the quantitative effect of inflation.
4 a wide variety of vacuum valves, usually by the valve function, structure type, drive mode, materials and purposes of classification.
Imported vacuum ball valve product advantages:
1, the use of 1/4 rotating electric device, the work is stable and reliable, can be installed in any direction, the valve stem will not move.
2, the valve on and off the electrical signal output, expert, dual-use.
3, simple and compact structure, small and portable, easy disassembly and maintenance, and can be installed in any position.
4, 90 degree rotation, open and close rapidly, can be installed in many stations, not affected by the flow of media.
5, compact structure, light weight, easy to install. Small flow resistance, large circulation, easy operation.
6, the choice of different parts and materials, can be used for different levels of corrosive media.
