Description

Electromagnetic valve Technical Field The utility model relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve. Background With large-scale concentrated planting of land, farmland irrigation and garden irrigation have higher demands on valves, and are mainly represented by: 1. The electromagnetic valve is matched with a sensor, is remotely monitored, and can realize intelligent remote control through PLC control, so that the labor cost is saved; 2. The power supply has the function of randomly selecting various AC/DC power supplies, and can be well adapted to various power supplies on site; 3. Under the condition of circuit failure, the valve is manually opened and closed on site; 4. has the flow regulating function. The main valve sealing surface is a plane, is easy to leak and is not beneficial to sealing; 2, the whole appearance is the same color (most of the valve is black), the manual switch is a very small part which is not easy to be found and identified by a user, 3, the valve main passage has no flow regulating function or only has flow regulating function, does not have the function of closing the valve under emergency, and 4, the valve main passage has no multiple valve schemes under emergency. Disclosure of utility model In order to overcome the defects of the prior art, the utility model provides the electromagnetic valve, and the problems of the electromagnetic valve are effectively solved.
