Introduction of high-pressure ball valve: Ball does not have a fixed-axis ball valve, known as the floating ball valve, also known as floating ball valve. Floating ball valve body has two seat ring seal, clamping a ball between them, the ball has a through hole, the diameter of the through hole equal to the pipe diameter, said full-diameter ball valve; the diameter of the through hole slightly smaller than the pipe The diameter, said reduced diameter ball valve. The ball body is free to rotate in the seat ring by means of a valve stem. When opened, the ball holes are aligned with the pipe diameter to ensure that the working medium resistance of the pipe is minimized. When the valve stem rotates 1/4 turn, the ball hole is perpendicular to the valve passage, and the ball is tightly pressed against the valve seat sealing ring on the outlet end by the pre-tightening force and medium pressure applied to the two valve seat sealing rings to ensure that the valve Completely sealed. This ball valve is a one-sided forced seal. Application of high pressure ball valve: Floating ball valve for general industrial use, and is suitable for chemical, petroleum, natural gas, metallurgical and other industries and containing hydrogen sulfide medium, impurities, serious corrosion of natural gas long-distance pipeline. Floating ball valve according to different requirements, based on the shell material is divided into: ordinary carbon steel series WCB, A105; 304,316 stainless steel series; low temperature steel series LCB, LCC; anti-sulfur series. Structural characteristics of high-pressure ball valve: Floating ball valve is characterized by the main ball without the support shaft, the ball was two seats which were held in a "floating" state, which is mainly used in the pipeline to cut off, distribute and change the direction of medium flow. The main features of the floating ball valve seat seal design, reliable sealing valve stem seal, fire electrostatic function, automatic pressure relief and locking devices and other structural features. High-pressure ball valve structure description: 1. Valve with open and close position instructions; 2. Locking device; 3. Stem fly-proof structure; 4. Anti-static device; 5. Fire structure; 6. Unique seat sealing structure; Medium flange (body and left body connection) no leakage structure.
