[0002] A water supply and sanitation system is an important component of a high-speed motor train unit, and a sewage transfer box vacuum deficiency fault of the water supply and sanitation system is also one of common typical faults. For a CRH6A motor train unit with a long operation time, the water supply and sanitation system frequently reports a "sewage transfer box vacuum deficiency" fault. The fault is mostly caused by cracking of a rubber of a sewage HOSE valve, and can be solved by replacing a new sewage HOSE valve. During replacement of the sewage HOSE valve, a flange connector on the sewage HOSE valve needs to be disassembled. Currently, on-site traditional disassembly of a flange bolt is mainly completed by manual cooperation: one operator uses a pipe wrench to fix the sewage HOSE valve, and another operator uses two iron rods to clamp the bolt to loosen it. The operation process consumes a long time, requires two people to cooperate, is prone to slipping, brings great difficulty to construction operation, even affects product performance, and also has safety risks such as bruising and bruising. Therefore, there is currently a lack of a device specially used for disassembling and assembling the sewage HOSE valve of the toilet of the motor train unit to simplify disassembly and assembly and shorten disassembly and assembly time, thereby improving replacement efficiency of the sewage HOSE valve.
