An annular groove 9 is opened on one side of the flange 3, and a sealing strip 10 is fitted to the inner wall of the annular groove 9. By having the operator slide the annular plates 5 outward along the valve body 1, the sleeve plate 7 is placed on the outside of the connecting pipe, and then the clamping screws 8 are turned inward, so that the four clamping screws 8 form a connection with the connecting pipe. The clamping or clamping screw 8 is placed on one side of the pipe flange to form a limit, so that the flange 3 is connected to the spliced ​​pipe. This makes it easier for the staff to install bolts between the flange 3 and the connected pipe, prevents the valve body 1 from moving during installation, and reduces the difficulty of connecting the flange 3 and the pipe. At the same time, the sealing strip 10 in the annular groove 9 is placed between the valve body 1 and the pipe to ensure the connection seal. After the sealing strip 10 is damaged by long-term use, the bolts between the pipe and the valve body 1 can be removed, and then the sleeve 7 and the clamping screw 8 can be used to fix the valve body 1 to the side of the connected pipe, so that a gap is created between the valve body 1 and the pipe, and the sealing strip 10 can be pulled out for replacement without disassembling and reconnecting the valve body 1, which improves the convenience of the device during installation.

[0020] Reference Figure 2 and Figure 3 As shown in this embodiment: a conical ring 4 is fixedly connected to one side of the flange 3. The conical ring 4 has a conical structure. When both ends of the valve body 1 are connected to the pipeline, the conical ring 4 is inserted into the connecting pipeline, so that the conical ring 4 is placed inside the gap between the valve body 1 and the pipeline, thereby filling and sealing the gap, further improving the sealing performance of the valve body 1, and preventing water from seeping out of the connection gap.

[0021] Reference Figure 2 and Figure 3As shown in this embodiment: both ends of the inner diameter of the valve body 1 are fixedly connected to protruding plates 11, and both ends of the inner diameter of the valve body 1 are fixedly connected to arc-shaped protrusions 12. A filter screen 13 is inserted between the protruding plates 11 and the arc-shaped protrusions 12. By setting the protruding plates 11 and the arc-shaped protrusions 12 to form a groove, and the arc-shaped protrusions 12 are made of rubber, the filter screen 13 can be squeezed to one side by the arc surface of the arc-shaped protrusions 12 and the properties of the rubber material, causing the arc-shaped protrusions 12 to shrink and slide into the gap between the arc-shaped protrusions 12 and the protruding plates 11, thereby installing the filter screen 13 on one side of the inner diameter of the valve body 1.
