[0002] Sealing valves are mechanical devices that control the flow rate, direction, pressure, and temperature of a flowing fluid medium. They are essential components in pipeline systems and can be adjusted by rotating with manual tools or operated with handwheels, handles, pedals, and the like. Current valves connect the flanges at the ends of pipe fittings via flanges. When disassembling a sealing valve for maintenance, the bolts between the sealing valve flange and the pipe end flange must be removed. However, bolt removal is a complex and time-consuming process, requiring the nuts on all the bolt ends to be unscrewed and the bolts to be removed from the flange mounting holes before the flanges can be disassembled. Therefore, those skilled in the art have provided a sealing valve that is easily disassembled to address the issues raised in the aforementioned background technology. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By arranging the bolt installation groove on the flange, the bolts and nuts do not need to pass through the bolt installation groove from both sides when installing, but can be directly installed from the side and the nuts can be tightened. When removing the flange, the nuts can be directly loosened and the bolts can be taken out from the side, which is more convenient to operate, saves operation time and improves efficiency.
