A packing 220 is disposed between the valve body 200 and the valve cartridge 300. The sealing gasket 220 can enable the ball valve to have a good sealing effect, and the sealing effect of the ball valve is effectively guaranteed.
The valve core 300 is connected with the valve rod 500, the valve rod 500 is connected with the handle 600, the valve rod 500 is driven to rotate through the operation of the handle 600, the valve rod 500 rotates the valve core 300 to rotate, and the opening, closing and the closing of the ball valve are realized. The first filter ring 310 is arranged in the inlet flange 120 at the water inlet of the valve core 300, and when liquid flows through the first filter ring 310, the first filter net 313 can filter impurities in the water, so that the impurities flowing through the contact part of the valve body 200 and the valve core 300 are reduced; the liquid or foreign matter of the first outer side is biased toward the first inner side due to the pressure difference, so that the foreign matter is less dropped into the gap between the valve cartridge 300 and the valve body 200. Similarly, the second filter screen 323 on the second filter ring 320 can filter impurities, and the pressure at the second inner side of the second inner ring 321 is lower than the pressure at the second outer side, so that the impurities are reduced in the gap between the valve element 300 and the valve body 200 when the liquid flows out of the valve element 300. The sealing ring 314 abuts against the valve element 300 to improve the sealing performance of the ball valve. The gasket 210 allows the valve body 200 to be coupled to the outlet flange 110 and the inlet flange 120 to provide a better seal for the ball valve.
