With the rapid development of science and technology and the continuous improvement of production technology and product structure, cast steel ball valve has become the main valve class in daily use in industrial sector in a very short time. For some industry veterans, cast steel ball valves are familiar, but for some industry novice, cast steel ball valves are unfamiliar.
First of all, we should have a certain understanding of the cast steel ball valve.In our country, cast steel ball valve plays a very important role in the national economy, which is widely used in a series of industries, such as chemical industry, papermaking, pharmaceutical, water conservancy, electricity, municipal, iron and steel and so on. Moreover, in the developed countries of the West, its use in the industrial sector is also increasing.
Secondly, we need to know some of the basic operation of cast steel ball valve, that is, its working principle. Its working principle is very simple, that is, in the process of operation by rotating valve love to make the valve open or closed. There is also a very good point, that is, the cast steel ball valve switch is light, small in size, and it can be made into a large caliber, which greatly facilitates the daily use of the industrial sector. For some of its main characteristics, we should also understand, such as its compact structure, easy to operate and maintain, but also suitable for water, solvent, acid and natural gas and other general working media, in operation, not affected by them.
Next, let's talk about the advantages of cast steel ball valves. The first advantage is that, when in use, you will find that its fluid resistance is small, and it is very good that its drag coefficient is equal to the pipe segment of the same length. The second advantage is that it is simple in structure, small in size and light in weight, and during use, you will find it very convenient. The third advantage is that the operation is convenient, the opening and closing is rapid, the rotation is 90 degrees from the fully open to the full turn, and the remote control is facilitated. The fourth advantage is that the maintenance is convenient, the structure of the pneumatic ball valve is simple, the sealing ring is generally movable, and the disassembly and the replacement are convenient. The fifth advantage is that the range of application is wide, the path is small to a few millimeters, large to several meters, and can be applied from high vacuum to high pressure. The sixth advantage is that in the same type of pneumatic ball valve, the stainless steel pneumatic ball valve has been widely used in oil, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as people's daily life.
