The role of pneumatic plug valve can not be replaced
Pneumatic plug valves are unfamiliar to most people. But people who are often working outside or doing business are more familiar with it. Because they see more of the world, they also have a certain understanding of this role in the industrial industry.
Pneumatic plug valves have the same structure as ordinary ball valves and butterfly valves, and their roles are similar. Its structure is very simple and consists of four parts, namely the valve body and plug of the plug valve, and the glands of the packing and packing. Since it consists of only four basic parts, its volume is not so large that it can be arbitrarily moved within the pipeline medium. It differs from the ball valve and the butterfly valve in that the pneumatic plug valve is operated very easily because it is opened or closed by the rotation of a plug body with a hole. However, one thing to note is that it opens and closes quickly, so pay attention to safety.
Relative to ball valves and butterfly valves, the fluid resistance of pneumatic plug valves is very small, which has led to its very popular use in industrial production. This is a very important feature for working in pipeline media. However, one thing to note when acting on a pipe is that the materials used in making the various components of the pneumatic plug valve are different, resulting in the pressure that it can adapt to, and the temperature is different. Therefore, different types of plug valves should be selected according to different pipeline media. For example, the more common is the valve body shell can withstand a pressure of 1.5, the maximum pressure the seal can withstand is 1.1, the temperature of the pneumatic plug valve is below 250 degrees Celsius, this time is suitable for nitric acid, oil type media Plays a role. As with other types of valves, where the maximum pressure that the valve body and the seal can withstand is small, the adaptable temperature will be reduced accordingly, and this time it is more suitable for water-based media.
A small pneumatic plug valve, although it does not seem to be a special eye, its role is that no other machine can replace it.
