In the process of rotating the connecting sleeve 203, the connecting sleeve 203 is fixedly connected to the guide ring 206 on one side close to the valve core 404. 07, and then the guide ring 207 rotates inside the valve body 1, thereby effectively ensuring that the valve body 1 and the connecting sleeve 203 rotate around the same center of a circle, with strong flexibility. At the same time, the limiting rod 301 slides along the inner wall of the limiting groove 302. When the fixing block 202 initially fixes the first mounting ring 201 and the second mounting ring 204, a nut 303 is threadedly connected to the end of the limiting rod 301, so that the bottom surface of the nut 303 contacts the surface of the second mounting ring 204, thereby effectively preventing the fixing block 202 from sliding into the groove 205 under the action of external force, and further fixing the first mounting ring 201 and the second mounting ring 204, thereby improving firmness. When it is necessary to control the opening and closing of the ball valve, it is only necessary to rotate the valve stem 403 through the hand wheel 405. Since the cross section of the valve stem 403 is a "convex" shaped structure, and the protruding part of the valve stem 403 conflicts with the connecting cover 402, the valve stem 403 is prevented from slipping out of the installation sleeve 401. It has strong flexibility. By rotating the valve stem 403, the valve stem 403 drives the valve core 404 to rotate, thereby effectively controlling the opening and closing of the ball valve. The operation is simple. Two sealing rings 406 are provided on one end of the valve stem 403 close to the valve core 404, which effectively ensures the sealing inside the ball valve. After the assembly of the ball valve is completed, it can be fixed at the specified position through the flanges 5 at both ends. The installation is simple.
