Water solenoid valve structure principle:
This valve pass through the diaphragm 15-100 to open the second
pilot valve solenoid valves 125-300 to pass through three open
pilot valve solenoid valve, its structure is dominated by the
Deputy valve and main valve components.
Depending on the state in which a power outage can be divided into
normally closed solenoid valve and a normally open solenoid valve.
Normally closed solenoid valve, normally position, vice valve port
plunger seal, pressure equalization valve chamber, vice valve, the
main valve port closed. When the coil is energized, the
electromagnetic force on the movable core pull, vice valve is
opened, the main valve cavity medium leakage from the pilot valve
port, so that the main valve diaphragm generating a pressure
difference between the upper and lower diaphragm was quickly hold
up, the main valve port open the valve was passage state. When the
coil power, the magnetic field disappears, the core reset, vice
valve port closed and then the secondary valve diaphragm chamber
pressure rises, the main valve diaphragm pressure to the valve seat
and the valve was closed.
