Structural Features Of Lined Ball Valve

The ball of the Lined Ball Valve floats. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly against the sealing surface of 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 working medium borne by the ball is all transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure shock, the ball may deflect. This structure is generally used for medium and low pressure ball valves. Floating ball valves are suitable for general industrial use. The main structural features of the floating ball valve are: (1) The valve is equipped with an open and closed position indicator (2) Locking device (3) Valve stem anti-flying structure (4) Anti-static device (5) Fireproof structure (6) Unique valve seat sealing structure (7) The middle flange (the connection between the valve body and the left body) has no leakage structure. Floating ball valves are divided into ordinary carbon steel series (WCB&A105), stainless steel series (304, 316), low temperature steel series (LCB, LCC), anti-sulfur series, etc. according to different usage requirements and based on the shell material.
