What are the vacuum valve manufacturers?

About vacuum valve, first of all, what is it, simply a kind of valve, its working pressure is lower than the standard atmospheric pressure. Mainly used in many vacuum industries, daily life we can also see a lot of applications over the vacuum valve items: such as wine, food, cosmetics, beverages, environmental protection, metallurgy, petroleum and chemical industries; there are many mechanical vacuum pumps in the industry on the special valves; can also be applied to the vacuum of the negative pressure system and so on. Below, a brief introduction to the manufacturer's information and its related content.?

We can understand that the vacuum valve can be specifically subdivided into many types. Then, what is its working principle? In fact, the vacuum valve is mainly the compressed air discharge, the air in the pump chamber is compressed and discharged out of the pump, through this operation can produce a negative pressure in the pump chamber, so that the atmosphere can be introduced into the system; under the pressure of atmospheric pressure, the outside world air will enter the negative pressure of the pump chamber, be compressed and discharged. By running repeatedly in this way, the air inside a container can be pumped out. A variety of different types of vacuum valves are widely used in industrial production, you can check more other related information.
