Overflow protection valve with built-in reset function.

Abstract

ocr An overflow protection valve includes a valve body that comprises the inlet, outlet, and pressure relief section. The inlet, including the outlet, and the pressure relief valve are positioned in the pressure relief section of the equipment. A new valve is installed inside the pressure relief valve, and a push rod for an overflow protection device is also installed. The inlet includes a flow-stopping component that blocks the outlet when under pressure. Flow exceeds the set limit when the push rod is moved by force; one end of the push rod moves. At the position where the flow-stopping component blocks the outlet channel after abnormal blockage, simply... The push rod operation moves the flow-stopping component to release the obstruction; the user can then release the obstruction. The overflow protection device for fluids can be easily prevented by operating the device again.
