[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1-4 The embodiment of the utility model is a ceramic ball core structure with large flow capacity, which includes a valve seat 1, a ball core 7 arranged inside the valve seat 1 and a connecting pipe 2 fixedly connected to one end of the valve seat 1. A step structure is provided inside the connecting pipe 2. A filter plate 6 is provided on the side of the step structure of the connecting pipe 2 away from the ball core 7. The side of the filter plate 6 away from the ball core 7 is set as an arc structure. An inlet pipe 3 is provided at the top of the connecting pipe 2 and located between the filter plate 6 and the ball core 7. A drain pipe 4 is provided at the bottom of the connecting pipe 2 and located on the side of the filter plate 6 away from the water inlet pipe 3. Valves 5 are provided on the outside of the water inlet pipe 3 and the drain pipe 4. The fluid inside the valve seat 1 flows from the connecting pipe 2 to the valve seat 1.

[0023] As the fluid flows through the connecting pipe 2 and valve seat 1, the filter plate 6 can be used to filter out larger particles of impurities in the fluid, ensuring the purity of the fluid. At the same time, the side of the filter plate 6 that contacts the fluid is designed with an arc structure to reduce resistance to fluid flow, thereby ensuring good fluid circulation. An inlet pipe 3 is provided on the backwater side of the filter plate 6. When the filter plate 6 needs to be cleaned, the ball core 7 is closed and the valve 5 is opened. Clean water enters the connecting pipe 2 through the inlet pipe 3, flows from the backwater side of the filter plate 6 to the contact side, and is discharged through the drain pipe 4, flushing away impurities and sediment attached to the surface of the filter plate 6. The filter plate 6 can be effectively cleaned without disassembling it, thereby improving the convenience and efficiency of maintenance. After cleaning, the filter plate 6 restores its filtering performance, ensuring the smooth flow of the internal fluid.

[0024] A valve stem 8 is rotatably connected to the inside of the valve seat 1 and located on the top of the ball core 7. The bottom end of the valve stem 8 is fixedly connected to the ball core 7, so that the opening and closing of the ball core 7 can be completed by the valve stem 8. A scale dial 9 is fixedly connected to the top of the valve seat 1 and is sleeved on the outside of the valve stem 8. An indicator needle 10 set towards the scale is fixedly connected to the outside of the valve stem 8. When the valve stem 8 rotates, the indicator needle 10 is driven to rotate. The cooperation with the scale dial 9 makes it easy to intuitively observe the opening state of the valve 5, so as to more accurately understand the opening and closing degree of the ball core 7.

[0025] The filter plate 6 is mounted inside the connecting pipe 2 via bolts 13. The heads of the bolts 13 are countersunk within the connecting pipe 2, ensuring a secure installation without affecting fluid flow. A sealing ring 12 is installed on one side of the stepped structure of the connecting pipe 2, covering the outside of the bolts 13. This seals the connection between the bolts 13 and the connecting pipe 2, reducing impact or corrosion on the bolts 13 from the flowing fluid, ensuring a good connection and facilitating removal of the bolts 13 as needed.

[0026] In order to facilitate connection and installation, the ends of the connecting pipe 2 and the valve seat 1 that are separated are fixedly connected with flanges 11 , and the entire ceramic ball core structure can be conveniently connected to other pipes or equipment through the flanges 11 .

[0027] Working Principle: As fluid flows through the connecting pipe 2 and valve seat 1, the filter plate 6 filters out larger particles of impurities, ensuring fluid purity. The surface of the filter plate 6 that contacts the fluid is designed with a circular arc structure to reduce resistance to fluid flow, thereby ensuring good fluid flow. An inlet pipe 3 is located on the backwater side of the filter plate 6. To clean the filter plate 6, close the ball core 7 and open the valve 5. Clean water enters the connecting pipe 2 through the inlet pipe 3, flows from the backwater side of the filter plate 6 to the contact side, and is discharged through the drain pipe 4, flushing away impurities and sediment adhering to the surface of the filter plate 6. Effective cleaning can be achieved without disassembling the filter plate 6, thereby improving maintenance convenience and efficiency. After cleaning, the filter plate 6 regains its filtering performance, ensuring smooth flow of the fluid within.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
