Liquid level regulating valve with high-pressure cut-off function

The utility model relates to the technical field of valves. The liquid level regulating valve with the high-pressure cut-off function comprises a valve body, a valve seat and a valve element, the valve element and the valve seat can move relatively, a first hard alloy layer is arranged on the valve seat, a second hard alloy layer is arranged on the valve element, and the valve seat and the valve element are in contact fit through the first hard alloy layer and the second hard alloy layer to achieve mutual sealing. The utility model discloses a liquid level regulating valve with a high-pressurecut-off function. The valve seat and the valve core are in contact fit through the first hard alloy layer and the second hard alloy layer to realize mutual sealing; under the same conditions, according to the liquid level regulating valve, the degree of local abrasion caused by long-term high-pressure erosion of the contact surface between the valve seat and the valve core is greatly reduced, sothat the inner leakage deg
