[0002] A ball valve is a valve that controls the flow of a pipeline by rotating the ball around its axis via the valve stem. It is usually spherical with a channel formed in the middle of the ball. It is made of a variety of materials, including stainless steel, copper, cast iron, etc. By rotating the ball, the flow of the pipeline can be controlled. 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.

The installation steps of the ball valve are cumbersome, so disassembly is complicated, time-consuming and labor-intensive, and cannot meet the inspection needs of staff. At the same time, they cannot be adjusted according to needs during the installation process and cannot adapt to different installation situations. Utility Model Content

A friction layer is installed between the placement groove 3 and the connecting block 4. The connecting block 4 can be placed more stably in the placement groove 3 through the friction layer to prevent the ball valve body 2 from shaking. The connecting block 4 is slidably connected in the placement groove 3. An adjustment component is installed on the base 1, and the adjustment component includes an extension block 12 fixedly connected to the side walls at both ends of the base 1. Two mutually symmetrical fixed blocks 13 are slidably connected to the side walls of the base 1. A group of mounting holes 16 are provided on the two fixed blocks 13.
