Inlet Valve - Midea G01 Service Manual

4.OVERVIEW OF MAIN COMPONENTS

4.11.2 Inlet valve

Working principle of inlet valve
Inlet valve has two main components: One is the 220V winding which Set in the injection
molding nylon colophony Pa66 outside cylindrical cavity and there is an iron core inside
of cavity. And normally, iron core is not in the center of cavity due to the spring force.
Once power supplys, the magnetic field produced by winding generate force overcoming
the spring force to drive iron core, which open the hole of releasing pressure in the inlet
valve.
The other is the channel part. There is a hole between inlet and outlet that control flux.
The default of the hole is closed and controlled by the hole of releasing pressure in the
inlet valve.
As a result, the fluxing hole can be opened on the condition of power supply, iron core
moving and the hole of releasing pressure.
In a word, inlet valve works in the condition of power supply and water pressure.
Characteristics of inlet valve:
1.Flux: the flux of inlet valve is different by
different manufacturer produced. And the flux
value usual is from 8L/min to 12L/min (the flux
value of this machine is 9.5L/min).
2. Modality: the inlet valve is common single-head
valve for the atmosphere can be programmed for
mechanical models, the direction of water flow
when a cam driven by program - controlled link,
Plectrum agencies to achieve watershed; The
second category is double-head valve, which is
used in electronic-type program - controlled
washing machine, and usually water influent from
the "pre-wash"box, and the other washing box is
the main box, and when the two valve boxes at the
same time electricity, water influent from the rinse
box, its on / off is control by PCB panel.
The last category is three-head valve, which is used
in electronic device programmed with the function
of drying washing machine, two of grids have the
same functions as well followed. And the third one
is used to control condensed water, which has
small flow.
3.Resistance: the resistance of single-head valve is
about 4000Ω。
4.Power value: the power value of single-head
valve is about 5W.
