This proportioner is suitable for low pressure and small flow, multiple gas single/mixed continuous gas supply systems. It is especially convenient to switch a variety of gases without causing the atmosphere to enter the heating tube.
The gas flow can be read on the same plane, and the digital display of the digital tube is highlighted, and the appearance is beautiful and practical, and the operation is simple.The gas flow rate is accurate and the control accuracy is high, which can effectively control the gas intake amount.All inlet and outlet ports and valve connections are connected by unions for easy maintenance and disassembly.
Working principle
The two (or more) kinds of gases in gas cylinder are decompressed through the pressure reducing valve to the required pressure (0.05MPa~0.3Mpa) and input to the gas mixing proportioner, and then by adjusting the volume flow of each component, the mixed gas of the predetermined proportional relationship is output to achieve the atmosphere required by the experiment. It is strictly forbidden to supply hydrogen and oxygen at the same time to ensure safety.
