Dual-Valve Pressure Controller Operation and Principle - Focus on Microfluidic Control Technology

Double valve pressure controller operation and principle is simple
The dual valve pressure controller operating principle is an automatic controller which receives the pressure signal and acts. The dual-valve pressure controller has a pressure setting function. When the pressure in the equipment system reaches or exceeds the pressure controller's set upper limit, the dual-valve pressure controller will automatically cut off the circuit, so that the equipment will stop and play an automatic protection role. When the system pressure is lower than the lower limit of the set pressure, the dual-valve pressure controller automatically turns on the circuit to restore the device to normal operation.
The principle of double-valve pressure controller is relatively simple, mainly when the pressure in the system is higher or lower than the rated safety pressure, the inner disc of the sensor moves instantaneously, and the switch connector is pushed or disconnected by connecting the guide rod. When the pressure drops to or rises above the rated recovery value, the disc is instantaneously reset, the switch is automatically reset, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the double valve pressure controller either directly or through After the comparison, the switch element is pushed to change the on-off state of the switch element, and the double valve pressure controller achieves the purpose of controlling the measured pressure. The elastic components used in pressure switches include single-ring spring tubes, diaphragms, bellows, and bellows.
Dual valve pressure controller features:
1. The double-valve pressure controller adopts inch pipe thread, quick connector or brazed pipe, and the double-valve pressure controller is flexible and convenient to install without special installation and fixing.
2. The fixed pressure switch has two kinds of connection methods, ie, insert type and wire type, which can be freely selected by the user.
3, within the pressure range can be manufactured according to the user's arbitrary selected pressure value.
4. The chattering time is very short, reducing wear to zui, improving the reliability of the dual valve pressure controller.
5, manual control, do not need any tools to conduct electrical contact function test.
6. The dual valve pressure controller has a very low differential value and can be used for ground pressure control.
