[0018] like Figure 3As shown, the operating component 5 includes a valve seat 1 54, the outer wall of which is engaged with the inner wall of the valve body 1, a valve seat 2 55 overlapping the right side of the valve seat 1 54, the outer wall of the valve seat 2 55 being engaged with the inner wall of the valve body 2, a ball valve 51 being rotatably connected to the inner walls of the valve seat 1 54 and the valve seat 2 55, a handle 52 being fixedly connected to the upper surface of the ball valve 51, the outer wall of the lower part of the handle 52 being rotatably connected to the inner cavities of the valve body 1 and the valve body 2 respectively, an annular retaining plate 58 being fixedly connected to the left side of the valve seat 2 55, the outer wall of the annular retaining plate 58 being engaged with the inner cavity of the valve seat 1 54, and a limit housing 53 being fixedly installed on the outer wall of the lower part of the handle 52. The valve seat 54 and valve seat 55 fill the gap between ball valve 51 and valve body 1 and valve body 2, thereby preventing liquid residue, reducing internal corrosion, and improving service life.

[0019] like Figure 4 As shown, sealing rings 57 are snapped into the inner cavities of valve seat 1 54 and valve seat 2 55. Annular limiting plates 56 are fixedly connected to the outer walls of the two sealing rings 57.

Then, the arc-shaped support plate 41 and the arc-shaped support plate 42 support and restrict the limiting shell 53, thereby facilitating installation and disassembly.

[0022] The working principle of this utility model is as follows: First, the ball valve 51 is placed between valve body 1 and valve body 2. Then, valve body 1 and valve body 2 are snapped together. At this time, the ball valve 51 is located inside valve seat 1 54 and valve seat 2 55, while the upper limiting shell 53 is limited between arc-shaped support plate 1 41 and arc-shaped support plate 2 42. Then, the annular connecting plate 1 31 and annular connecting plate 2 32 are connected and fixed by several bolts 33, so that valve body 1 1 and valve body 2 2 can be connected and fixed with the assistance of annular sealing plate 21 and sealing ring 1 22, thereby completing the installation and fixing of the ball valve 51. Then, it can be connected to the pipeline through the flanges at opposite ends of valve body 1 1 and valve body 2 2. When in use, the ball valve 51 can be rotated by the handle 52. Through the action of valve seat 1 54 and valve seat 2 55, there is no gap between the outer wall of the ball valve 51 and valve body 1 1 and valve body 2 2, thereby preventing liquid residue.
