Pressure switch and electromagnetic valve operating principle
what! Upstairs that is too professional, it is necessary to design these devices to understand the talent. Popular pressure switch is quite a button switch is only the power of your original finger on the pressure we need to test to complete the need to complete. Electromagnetic commutation method, but in this it is provided by the external device to control the power to complete, and perhaps this control device is said before the pressure switch.
Simply put, the pressure switch is a switch, as long as its inlet pressure exceeds its set value, you can open or the pressure signal into electrical signals to control the work of other components. The electromagnetic valve is to use the electrical signal to control the work of the spool, as long as the access to a certain current, you can achieve changes in the direction of liquid flow, thus controlling the commutation of the implementation of components. The source of the electrical signal can be a pressure switch or a trip switch.
