1. Product Overview
The electric ball valve is a rotating ball valve with a rotation angle of 90 °. It has excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, and long service life. The valve body channel and the connecting pipe diameter are equal and form a diameter. Can flow through without loss. Products are usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in petroleum, chemical, metallurgy, light industry, papermaking, power stations, refrigeration, etc. Work field.
Ball valve is an important type of valve, which is widely used in petrochemical, long-distance pipeline and other fields. Ball valve closure is a ball with a hole (or part of the ball), the ball with the valve stem rotation, to achieve the opening or closing of the valve. The ball valve can be fully closed and fully open by rotating 90 °. Compared with gate valves and globe valves of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
2. product performance characteristics
1. The fluid resistance is small, the ball valve is the smallest fluid resistance in all valves, even if the ball valve, the fluid resistance is quite small.
2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem long-term operation balance and flexibility.
3. The valve seat sealing performance is good, the sealing ring made of PTFE and other materials, the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The valve stem seal is reliable, because the valve stem only for rotating movement and do not do lifting movement, the valve stem packing seal is not easy to damage, and the sealing capacity increases with the pressure of the medium.
Due to the PTFE and other materials have good self-lubrication, and the ball friction loss is small, help ball valve long service life.
6. Undermounted stem and stem head convex step to prevent stem spray, such as fire damage caused by stem seal, convex step and valve body can also form a metal contact, to ensure that the stem seal.
