Ball valve is mainly used to open and close the pipeline and equipment media purposes. The main advantages of the ball valve are as follows: For regular operation, quick opening and closing, light. Small fluid resistance. Simple structure, relative size, light weight, easy maintenance. Sealing performance is not limited by the installation direction, the flow of media can be arbitrary. No vibration, low noise. The main shortcomings of the ball valve are as follows: According to the structure of the ball valve can be divided into: floating ball valve, fixed ball valve, ball valve and flexible ball valve; according to the channel can be divided into straight, angle and three-way, three- T-shaped and L-shaped two. By connecting workers can be divided into threaded connection, flange connection and welding three. Ball valve installation and maintenance should note the following: to leave the valve stem rotation position can not be used for throttling. Ball valve with gear should be upright installation.
