Ball valve is mainly used to cut off or connect the medium, and can also be used for the regulation and control of the fluid. Widely used in petroleum, chemical, metallurgy, electric power, construction, heat, water supply and drainage, water treatment and other industries. Valves according to American standards are called American standard valves. Applicable to various pipelines of Class150~Class1500. The closing part of the American standard ball valve is a sphere, and the sphere rotates around the center line of the valve body to open and close a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. There are mainly API and ASME standards, and ASTM is the material standard.

Flange ball valve :Its closing part is a sphere, and the sphere rotates around the center line of the valve body to open and close a valve. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.The  flange ball valve can be divided into straight-through type, three-way type and right-angle type according to its channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium.

1 Floating ball valve: The ball of the ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on 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 ball bearing the working medium is all transferred 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. This structure is widely used in medium and low-pressure ball valves. The Xinhong ball valve belongs to a floating ball valve.

2 Fixed ball valve: The ball of the ball valve is fixed and does not move after being pressed. The fixed ball valve has a floating valve seat. After being pressurized by the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the sealing. Bearings are usually installed on the upper and lower shafts with the ball, and the operating torque is small, which is suitable for high-pressure and large-diameter valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil-sealed ball valves have appeared in recent years. Special lubricating oil is injected between the sealing surfaces to form an oil film, which not only enhances the sealing performance but also reduces the operating torque. , more suitable for high-pressure and large-diameter ball valves.

3 .Elastic ball valve:The ball of the ball valve is elastic. Both the ball and the valve seat sealing ring are made of metal materials, and the sealing specific pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. This valve is suitable for high temperature and high pressure medium. The elastic sphere is obtained by opening an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity. When the channel is closed, the wedge head of the valve stem is used to expand the ball and compress the valve seat to achieve sealing. Before turning the ball, loosen the wedge head, and the ball will return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.
