[0020] The present invention is further described below with reference to the accompanying drawings: As shown in the figure, the automatic reset lever remote manual regulating valve includes a valve body 1 and a valve stem 2, wherein a valve core 3 is provided in the valve body, the valve stem is connected to the valve core, and a bracket 4 is mounted on the valve body; a handle 41 is rotatably connected to the bracket, the valve stem is connected to the handle, and its tail end is used for manual rotation; a push rod 5 is movably mounted on the bracket; an elastic member 51 is mounted on the bracket and applies force to press the push rod against the end of the valve stem to keep the valve core in a closed state. A long slot can be provided on the handle for connecting to the valve stem, specifically, it can be connected to the long slot by a screw passing through the valve stem; the elastic member can be a spring, etc., for providing power for the valve stem to descend and close, specifically, the elastic member is fixed on the push rod, the push rod is fixed on the top of the valve stem, one end of the handle is connected to the bracket, the middle end is connected to the valve stem, and the tail end is used for manual operation.

[0021] In this embodiment, as shown in the figure, a chain 42 for manual operation is provided at the tail end of the handle. By attaching the chain to the lever hole (or welding or other methods), remote manual operation is achieved, keeping the work area away from dangerous (flammable, explosive, radioactive, toxic) areas, ensuring safe and reliable operation.

[0022] In this embodiment, as shown in the figure, the elastic member is a spring.

[0023] In this embodiment, as shown in the figure, the bracket includes a mounting frame 43, the ejector rod includes a mounting plate 55 and a ejector head 52.
