Seven advantages of ball valve
ball valve and plug valve belong to the same type of valve, only its closing part is a sphere, which rotates around the center line of the valve body to open and close. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Ball valve is a new type of valve widely used in recent years. It has the following advantages: the cup punching experiment is to make the disc (60) sample of thin plate and strip compress on the blank holder, and polyurethane insulation materials will lead the stamping die of China's thermal insulation building materials market in a long period of time:
1 The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length
2. Simple structure, small volume and light weight
3. It is tight and reliable. At present, plastic is widely used as the sealing surface material of ball valve, with good sealing performance, and it has also been widely used in vacuum system
4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control
5. It is easy to maintain. The ball valve has a simple structure and can provide power with super current. The sealing ring is generally movable. It is convenient to disassemble and replace the unexpected shutdown due to stress corrosion cracking and other reasons
6. When it is fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the sealing surface of the valve
7. It has a wide range of applications, ranging from small to several millimeters and large to several meters, and can be applied from high vacuum to high pressure. Ball valves have been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life. (end)
