In the 1950s, ball valves gradually appeared in the industrial production of developed countries in the West. And its usage rate has been rising year by year, and people are constantly improving the performance. Nowadays in China, ball valves are mainly used in pharmaceutical machinery, petroleum refining, water conservancy and chemical industry, electric municipal papermaking and steel industries. These industries have a very important position in the national economy. Therefore, ball valves are also indispensable in these industries. equipment.
How does the ball valve stand out?
In the valve field, there are many kinds of valves. The reason why the ball valve can stand out from the crowd and be frequently used in various fields is inseparable from its irreplaceable advantages. So, what are the advantages of the ball valve?
First of all, the advantage that the ball valve can not be ignored is wear resistance. According to the technical personnel in the industry, for the valve, the wear resistance is an important factor to check the quality of the valve. The sealing material of the ball valve is alloy steel surfacing, and the general valve sealing ring is rubber or other metal. The alloy steel surfacing of the ball valve has good wear resistance.
“Everyone knows that the valve is a switch, it needs to be opened and closed, and at the same time the switch, the seal will be subject to relatively large wear, but the seal of the ball valve will not be like this.†Said.
Secondly, the sealing performance of the ball valve is very good. It is understood that the sealing of the ball valve is not machine-grinded, but artificial grinding, which ensures a higher degree of fit, so the sealing performance is very reliable.
In addition, the life of the ball valve is very long. This is also a point that production companies pay great attention to related production equipment.
“Because it is often used in all major production-line industries, if it is not long enough, it will become very troublesome and often cause a lot of mistakes.â€
Ball valve selection skills sharing
As a kind of opening and closing member with a valve stem, the ball valve is essential for the stability of the equipment. Therefore, some details need to be followed in the selection to better meet the actual needs.
Focus on size selection. It is understood that the flow resistance of the ball valve is generally small, the passage and the pipe are almost the same, so it can be used in some areas sensitive to the working conditions of the medium. When choosing such valves, pay attention to the choice of size, the size and weight are different, and the effect can be achieved.
Reasonably consider the price. When choosing a valve, in addition to shop around, you should also consider economics, as long as you can meet the actual needs, it is not a good choice to choose large size or heavy weight.
In addition, fixed ball valves have a closed valve cavity. If it is used in a low temperature medium or in an environment where gasification may occur, a valve with a bleeder must be selected. If necessary, the ball valve needs to be changed to a butterfly valve or a shut-off valve.
The industry pointed out that this type of valve is generally suitable for pipeline cuts with ball requirements. For the selection of such valves, it can be selected according to the needs of the channel structure, which can ensure the requirements of multiple channels and reduce the number of valves used as much as possible.
It is worth reminding that the choice of ball valve also needs to pay attention to the brand and price screening, it is wise to choose a cost-effective valve.
