The Sealing Form Of Ball Valve Is Divided Into Fixed Ball Valve And Floating Ball Valve.

Speaking of 3 Piece Threaded Ball Valve, this is a type of valve that is used in many industries, but do you know about floating ball valves? Different valves have different characteristics and their use also has its own advantages. So, what are the benefits of using floating ball valves? Let me give you a brief introduction below.

1. Among all kinds of valves, the flow resistance of the ball valve is the smallest, and after the entire valve is opened, the diameter of the entire channel is consistent with the pipeline, so the medium will flow very smoothly without any resistance. Especially the floating ball valve, it can be completely closed by rotating 90°, which can be said to be very convenient and quick to switch.

2. Compared with other valves, the floating ball valve has the characteristics of light weight, small size, convenient and suitable for various pipeline installation. At the same time, it is easy to install and has good airtightness. There is almost no leakage of the medium during use, especially when transmitting gas. The floating ball valve has a very good throttling effect on the gas.

3. The floating ball valve contains a locking device, which can ensure that the impact of misoperation on the valve switch is reduced during operation. That is to say, the floating ball valve has a locking hole in the fully open and fully closed positions of the valve, so as not to cause the valve switch caused by random touch.

Fourth, the valve stem of the floating ball valve has an anti-flying structure, and the valve stem is generally installed below, which can effectively prevent the valve from flying out under pressure. Moreover, this structure is made of metal, whether it is a fire or high-temperature operation, it can ensure the sealing of the valve stem.

The above are the benefits of using a floating ball valve. The industry generally believes that this is a relatively good valve, which is often used in pipeline transportation and has a long service life.

Fixed ball valve is one of the indispensable parts in the pipeline transportation industry. Almost every company needs to use it as long as there is a demand for liquid and gas transportation. However, in the actual operation process, there are still many problems that need to be paid attention to when using fixed ball valves. Let's take everyone to understand it together.

1. Before installing the fixed ball valve, be sure to clean the inside of the valve to ensure that there are no impurities before installing it. During installation, the bolts on the flange should be tightened symmetrically, which helps to ensure the airtightness of the fixed ball valve and also helps to speed up the installation of the valve.

2. During the daily maintenance or replacement of the fixed ball valve, be sure to confirm that there is no pressure in the pipeline before dismantling it, otherwise it will cause an accident. Because if there is air pressure in the pipeline, it will cause parts to fly out and injure people. Of course, you must be careful when disassembling the valve. When installing and producing, you must also pay attention to whether the valve has air leakage, and you also need to avoid injuries.

3. The components of the fixed ball valve are composed of metal parts and non-metal parts. During the cleaning process after use, the non-metal parts must be removed from the detergent in time after cleaning. Do not soak for too long. Non-metal parts can be cleaned with pure water or alcohol. After cleaning, the metal parts must be blown dry in time to avoid rust. Metal parts can be cleaned with organic solvents such as gasoline.

The above are some issues that need to be paid attention to during the use of fixed ball valves. Although it seems easy to understand, you must be careful to ensure safety and performance.
