Q11F one-piece ball valve
I. Introduction:
The Q11F one-piece ball valve and the flange gate valve belong to the same type of valves. The difference lies in that its closing part is a sphere, which rotates around the center line of the valve body to achieve the opening and closing of the valve. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. The wide-style ball valve is a new type of valve that has been widely adopted in recent years. The one-piece ball valve is a manually operated rotary ball valve with a rotation angle of 90°, featuring excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, easy maintenance and long service life. The one-piece ball valve is usually applied in occasions with strict sealing requirements. In addition to controlling gaseous, liquid and steam media, it is also suitable for controlling sewage and media containing fibrous impurities.
II. Product Features:
1. Small fluid resistance. The ball valve is one of the valves with the smallest fluid resistance among all valve types, and even the reduced-bore ball valve has quite small fluid resistance;
2. Quick and easy switching. As long as the valve stem rotates 90°, the ball valve can complete the full opening or full closing action, making it easy to achieve quick opening and closing;
3. Good seat sealing performance. Most of the sealing rings of ball valves are made of elastic materials such as polytetrafluoroethylene. The soft-sealed structure is easy to ensure tight opening and closing, and the sealing force of the ball valve increases with the increase of the medium pressure;
4. Reliable valve stem sealing. When the ball valve is opened and closed, the valve stem only rotates without lifting, so the packing of the valve stem is not easy to be damaged, and the sealing force of the valve stem back seal increases with the increase of the medium pressure;
5. Due to the excellent self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the sphere is small, so the service life of the ball valve is long;
6. It can be equipped with various driving mechanisms such as pneumatic and electric actuators to realize remote control and automatic operation;
7. The inner channel of the valve body is smooth, so it can transport viscous fluids, slurries and solid particles;
8. Easy to install, and can be installed in any position of the pipeline in any direction.
