With the continuous progress of science and technology, ball valves have become an indispensable product in people's lives, such as the faucet used by people is a simple ball valve. The ball valve generally comprises a valve body, a valve stem, a ball core, the valve body is provided with an inner cavity, a medium inflow channel and a medium outflow channel that is conducted with the inner cavity, the ball core is arranged in the inner cavity, the ball core is provided with a guide channel, the valve stem is linked with the ball core, and the ball core is driven to rotate by the valve stem, so as to control the conduction between the guide channel and the medium flow channel and the medium flow out channel, so as to control the opening and closing of the fluid medium. According to the different working conditions in which the ball valve is located, some ball valves need to have the function of filtering the fluid medium, and the valve core of the existing ball valve can only achieve the purpose of opening and closing to the fluid medium, so that the valve core of the existing ball valve can only use a single function, and can not meet the use of the ball valve under special working conditions, and affects its practicability.
In order to solve this problem, engineers began to develop a new generation of ball valves with filtration functions to meet the needs of special working conditions. The new generation of ball valve has added a filter screen to the spool, which can effectively intercept impurities and particles in the fluid medium and ensure the purity and smoothness of the fluid medium. 
At the same time, the new generation of ball valves also adopts advanced materials and technologies, which make the valve core and valve stem more wear-resistant and corrosion-resistant, and improve the service life and stability of the ball valve. In addition, the new generation of ball valves is also equipped with an intelligent control system, which can realize the precise control and monitoring of the fluid medium, making the use of ball valves more convenient and safe. The R&D and application of a new generation of ball valves not only improve the practicability and reliability of ball valves, but also bring more convenience and benefits to people's lives and industrial production. In the future, with the continuous progress and innovation of science and technology, it is believed that ball valves will play a more important role in more fields and make greater contributions to the development and progress of mankind.
