| description | The invention relates to the technical field of ball valves, in particular to a hard sealing ball valve which comprises a valve body, valve seats, a valve ball, an upper valve rod and a lower valve rod, each valve seat is provided with a water inlet and a water outlet, the valve seats are arranged on the two sides of the water inlet and the two sides of the water outlet, the valve ball is jointly installed on the two valve seats, the upper valve rod and the lower valve rod are both connected with the valve ball, and the upper valve rod and the lower valve rod are connected with the valve body. The upper valve rod extends to the outer side of the valve body, the upper valve rod and the lower valve rod are both rotationally connected with the valve body, a connecting channel is formed in the valve ball, and a mounting cavity communicating with the connecting channel is formed in the lower valve rod. The buffer component is arranged to block fluid entering the valve ball, water flow impact is prevented from dire |
