Simulation hand valve with signal feedback

The utility model provides a simulation hand valve with a signal feedback function. The simulation hand valve comprises a hand valve body, a valve rod, a potentiometer assembly, a gear assembly, a display assembly and/or an electrical wiring port. One end of the valve rod penetrates into the hand valve body and is rotationally connected with the hand valve body, and the other end of the valve rod is located outside the hand valve body. The valve rod drives the potentiometer assembly to rotate through the gear assembly. The display assembly and/or the electrical wiring port are/is electrically connected with the potentiometer assembly, and the display assembly and/or the electrical wiring port are/is arranged on the outer surface of the hand valve body. According to the utility model, the real valve opening numerical value can be displayed, and the opening information of the valve can be fed back to a computer or displayed through a display screen when an operator operates, so that the operation of the operato
