An Analysis of the electromagnetic valve mechanical experts "severe"

Step by step action solenoid valve to direct the pilot solenoid valve, which can power off and off states can be divided into normally closed and normally open solenoid valve solenoid valve.

     Normally closed solenoid valve, coil energized, the armature of the electromagnetic force under the first drive vice valve Seti, the main valve cup of the fluid by the Vice-valve flow out, reducing the role of the main valve cup of the pressure, when the main valve reduce the pressure on the valve cup to a certain value, the armature driving the main valve cup, and use pressure leaving the main valve open cup, media circulation. Coil power, the electromagnetic force disappears, the whereabouts of the armature due to weight reduction.

     At the same time rely on media pressure, main valve to close off. Normally open solenoid valve, the suction after the coil is energized, moving core down, the Vice-pressure valve plug, the Deputy valve closed, the main valve pressure rise inside the cup, when the pressure rose to a certain value, the main valve cup as the upper and lower pressure, due to electromagnetic force, the moving core to promote the main valve cup, the clamping main valve seat, the valve closed.

     Coil power, the electromagnetic suction is zero, the Deputy valve plug and the moving core role of the spring lift, Vice valve is opened, the main valve cup of the fluid flow out by the Vice-valve, reducing the role of Cup in the main valve pressure, when the main valve to reduce pressure on the cup to a certain value, the use of pressure to push the main valve cup, the main valve is opened, the media flow.
