Electromagnetic valve with on-off state feedback function

The electromagnetic valve with the on-off state feedback function comprises a valve body, a valve cover, a magnetism isolating piece and a coil assembly which are sequentially connected, a liquid outlet channel is provided with a channel a, the valve cover is provided with a channel b and a channel c, the channel a is communicated with the channel c, the coil assembly is provided with a movable iron core connected to the magnetism isolating piece in a sliding mode, and the movable iron core abuts against the channel c. The electromagnetic valve further comprises a pressure sensor, a switching hole is formed in one side of the channel b, and the switching hole is connected with the pressure sensor. The purpose of the utility model is to detect and feed back the closing and opening pressure values of the electromagnetic valve through the pressure sensor, so that the working state of the electromagnetic valve and the electromagnetic valve are judged; closed-loop detection on the on-off state of the electromagnet
