The working principle of the HO-4 two-position four-way solenoid valve - Section 3 Initial state pressure in the control area
When the valve group is in the starting state, the two solenoid valves are opened, and there is gas input in both gas paths. This process is a stamping process, and both molecular sieves are pressurized to ensure efficiency.
Schematic diagram of two-position four-way solenoid valve
There are key components in the control cavity: the preloading spring and the diaphragm.
The preloading spring plays a role in returning to the original position when the solenoid valve is not started, that is, when the solenoid valve is not opened, the intake air goes directly to the molecular sieve. The diaphragm will adjust the position of the valve stem as the air pressure at both ends changes, thereby realizing the process of converting the electrical signal into the pneumatic signal.
The red area in the figure is the high-pressure area, the pressure in the yellow area is less than that in the red area, the green arrow is the direction of the air flow, and the molecular sieve intakes air.
Both solenoid valves are closed simultaneously, and both molecular sieves are inflated simultaneously.
