7. The working principle of the HO- 4 two-position four-way solenoid valve - Section 7 Pressure equalization, preparing for switching.
7. Pressure equalization, preparing for switching.
When the molecular sieve 1 is close to saturation, the two solenoid valves are closed, there is gas input in both gas paths and the pressure of the molecular sieve 1 is rapidly transferred to the molecular sieve 2 until the pressures of the two molecular sieves are equal. This process is a stamping process, and the molecular sieve 2 is pressurized quickly to ensure efficiency.
In the figure, the green arrow indicates the direction of the airflow. Due to the solenoid valve being closed, the yellow area is connected to the atmosphere, the valve stem moves to the side of the control cavity, and the diaphragm blocks the air inlet of the exhaust cavity, and the molecular sieve intakes air.
During the opening process, the two molecular sieves are connected by the valve group, and the pressure of the molecular sieve 1 is rapidly transferred to the molecular sieve 2 until the pressures of the two molecular sieves are balanced.
Both solenoid valves are closed simultaneously, and both molecular sieves are inflated simultaneously.
