How Does a Liquid Dispenser Diverting System Work?
Система отвода жидкости в колонках для дозаторов жидкостей, представленных на рынке, в основном основана на электромагнитных клапанах, которые в основном делятся на прямого действия, распределенные электромагнитные клапаны прямого действия и с пилотным управлением. Now let’s talk to you about what is the most appropriate shunt system for the liquid dispenser.
First of all, the working principle of the direct-acting solenoid valve is mainly to use the electromagnetic force generated after the electromagnetic coil is energized to open the valve, and the current breaks the valve in time to close. Because this solenoid valve does not have a pilot diaphragm, it does not use water pressure to stop the flow, so it is suitable for the diverting system of the liquid dispenser.
Then there is the step direct acting solenoid valve. Its working principle is: the direct acting and pilot type work together, when the step direct acting solenoid valve inlet and outlet pressure difference is equal, after the power on the current in the valve will be opened. When there is a pressure difference between the inlet and the outlet and the pressure difference reaches the starting value, the valve will be closed without current after power failure. Because the electromagnetic valve body volume is large and the flow rate is relatively large, it is not suitable for use as a liquid dispenser shunt.
The last is about pilot operated solenoid valves. The working principle of the pilot solenoid valve is: when energized, the internal pressure difference is formed so that the pressure difference and fluid pressure are combined to push the valve open; When the power is off, the valve is also closed by pushing down the pressure difference and the fluid pressure. This working principle is easy to fail in the process of use, so it is not suitable for the shunt system of the liquid dispenser.
How to Choose a Solenoid Valve for a Liquid Dispenser
Selecting a suitable solenoid valve requires more than comparing valve types. Manufacturers should consider the following factors:
Operating pressure: Confirm that the available inlet pressure meets the valve's requirements.
Flow capacity: Select a valve that matches the required liquid flow rate.
Installation space: Check the valve dimensions and available mounting space.
Operating reliability: Ensure that the valve can work consistently under the system's actual operating conditions.
Liquid compatibility: Verify that the valve materials are suitable for the chemicals or liquids being dispensed.
The most appropriate valve depends on the design of the liquid dispenser, the required flow rate, and the operating conditions.
Careful selection helps improve dispensing reliability and supports consistent system performance.
