The invention discloses an electromechanical electromagnetic valve which comprises an electromagnetic self-locking device, a static iron core, a piston, a signal strut, a main valve coil, a moving iron core, a small valve, a valve body, a coil component and an outer shell. The electromagnetic self-locking device is arranged at the top end of the static iron core, and the signal strut is arranged in the static iron core. The moving iron core is embedded in the static iron core, and the top end of the moving iron core is connected with the signal strut. The small valve is arranged at the bottom end of the moving iron core, and the piston is fixed to the outer side of the small valve. The piston is located at the lower end inside the valve body, and the static iron core is arranged at the upper end inside the valve body. The coil component is arranged in the electromagnetic self-locking device and sleeved with the outer shell. The electromagnetic valve is simple in structure and has the functions that the electromagnetic valve is maintained in a turned on state when outage occurs after the electromagnetic valve is turned on, and signals are fed back. When the electromagnetic valve needs to be turned off, as long as the electromagnetic self-locking device is powered, a main valve clack of the electromagnetic valve can automatically fall into a valve seat, and flowing of media in a pipeline is cut off.
Description
technical field [0001] The invention relates to the field of electromechanical technology, in particular to an electromechanical solenoid valve. Background technique [0002] Conventional solenoid valves have two structures: normally open and normally closed. The normally open solenoid valve is in the open state when the system is powered off, and in the closed state when the power is turned on. The normally closed solenoid valve is in the closed state when the system is powered off, and is in the open state when the power is turned on. The solenoid valves of these two structures cannot realize that the solenoid valve still maintains the original working state when the system is powered off. In order to ensure that the solenoid valve must be in the open state when it is powered on or off, and when the valve needs to be closed, the solenoid valve must have the function of closing the valve immediately. Leakage and short response time and so on. Due to the addition of the ...
