Ball valve ball is floating, under the action of medium pressure, the ball can produce a certain displacement and tight pressure on the outlet sealing surface to ensure that the outlet is sealed. The structure of the floating ball valve is simple and the sealing is good, but the load of the ball bearing the working medium is all passed to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium, and the ball may be offset when it is subjected to higher pressure impact.
