进口真空球阀｜进口球阀
德国托普进口真空球阀产品作用：
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。
4.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。

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.
