Vacuum ball valve is a type of valve specially used in vacuum environment. This type of valve has certain differences from ordinary ball valves. These differences determine that the environment they can meet is also different. Next, let's make a detailed introduction to the difference between the two.
The working pressure of the
vacuum ball valve is different from that of the ordinary ball valve. The vacuum ball valve is usually a pneumatic device. When the valve is twisted, the direction of the gas path can be realized by the reversing valve in the valve. At the same time, the flow rate can be changed according to the torque. Not only that, because the ball valve uses a spherical seal inside, it can be used under vacuum and low pressure. However, for ordinary ball valves, under the influence of the pressure of the medium, exceeding a certain pressure will affect its sealing performance, and it is impossible to realize the down control of the medium flow. Therefore, it is very important to choose a suitable type of ball valve under different pressures.
Performance difference
The performance of the vacuum ball valve is relatively good. This type of ball valve can also withstand the working load of the relevant medium in a high vacuum environment to ensure normal functions. But for ordinary ball valves, because they cannot withstand the excessive load generated by the medium, it is likely to cause the internal ball cotton to deviate due to the impact of high pressure. As a result, the sealing performance will be weakened, and even leakage of the medium will occur.
The difference between vacuum ball valve and ordinary ball valve is briefly introduced here. It is precisely because of the big difference between the two that you must choose according to your needs when choosing, and the appropriate ball valve can meet the needs of medium control.
