[0002] The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It realizes the communication, cutting and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control through the relative movement of the valve core and the valve body. It is widely used in petroleum and chemical production, especially in synthetic ammonia gasification systems. Reversing valves can be divided into many types according to needs, such as manual reversing valves, solenoid reversing valves, electro-hydraulic reversing valves, etc.; and the reversing valves on the market are mostly installed by internal and external threads when connecting the outlet pipe. During the process, in order to achieve a better sealing effect, sealing tape will be wrapped around the threads. This increases the difficulty of installation, and secondly, each disassembly needs to be rewound, which leads to a certain waste of use; finally, such disassembly and assembly is also time-consuming and labor-intensive.
