[0002] Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving mode. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. They can be closed tightly by rotating 90 degrees and with a very small torque. Ball valves are most suitable for use as switches and cut-off valves. However, existing ball valves do not have filtering functions, are difficult to disassemble and assemble, and are not easy to repair. The installation of the sealing structure is prone to gaps, which affects the sealing effect. Therefore, they do not meet existing needs.

[0003] In Chinese patent CN201921071239.2, a dovetail hard-sealed ball valve ball is introduced, in which the utility model installs a filter at the inlet and outlet of the spherical valve core. The filter can filter out impurities in the fluid. The filtered impurities will be deposited in the side valve body and can be discharged through the drain port, so that the valve can safely transport fluids containing impurities. However, technicians in this field have found in actual operation that when this structure is used, due to the limited filtering area of ​​the filter, the quality of the filtered medium per unit time is poor, resulting in the use effect of the ball valve not meeting the requirements.

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a dovetail type hard-sealed ball valve ball, which is fixedly connected to the ball through a mounting frame in the mounting frame through a mounting frame structure, thereby realizing fixed connection of the filter element. During this process, the locking bolts on the mounting frame can be connected and fixed with the positioning hole structure on the inner groove to achieve a stable effect, and the filter element structure placed inside can be limited by a diverter plate to filter the medium after the ball valve is opened, and after a specified time, it can be taken out of the mounting frame and replaced to achieve the effect of quick use.
