Briefly Introduction
The structure of the floating ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press against the sealing surface at the outlet end to ensure the sealing of the outlet end.
The floating ball valve has a simple structure and good sealing performance, but the load of the ball subjected to the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the spherical medium. This structure is widely used in medium and low pressure ball valves.
Strength
1. Easy to operate, open and close quickly, from full open to full off as long as rotated 90 °, easy to control over long distances.
2. the maintenance is convenient, the ball valve is simple in structure, the sealing ring is generally active, and it is convenient to disassemble and replace.
13. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the sealing surface of the valve.
