Summary
The mixed gas proportioning cabinet is that the gas to be mixed enters a two-stage or multistage pressure balancing device through a one-way valve to balance its input differential pressure, so as to ensure that the pressure of the component gas and the dilution gas is the same before mixing, and then adjust the flow control valve to adjust the flow of various gases according to the desired mixed gas ratio.
The principle of this series of products is to use dynamic gas mixing method, which ensures the uniformity of the mixed gas, excellent reproducibility, and stable proportion. It has an input undervoltage alarm function. When the input pressure of any gas is lower than the set lower pressure limit, it will sound and light dual alarms, while cutting off the output of the mixed gas, ensuring the accuracy of the mixed gas. The output is controlled by a digital pressure sensor, which makes the output flow more accurate and stable. Online, it can be used for welding mixture, electronic industry mixture, electric light source mixture, leak detection (alarm) mixture, disinfection mixture, etc.
The commonly used types of mixed gases include 0-50% carbon dioxide, other argon, 0-50% argon, other helium, 0-50% carbon dioxide, other nitrogen, 0-50% argon, other nitrogen, 0-2% oxygen, other argon, 0-10% hydrogen, other argon, 0-20% oxygen, other argon, 0-5% oxygen, 0-15% carbon dioxide, other argon, 0.5% oxygen, 26.5% helium, 8% carbon dioxide, other argon, 0.5% oxygen, 26.5% nitrogen, 8% carbon dioxide, and other argon
The mixed gas can reach -6 types, with a maximum input pressure of ≤ 3MPa, a maximum output flow rate of 15Nm3/h to 500Nm3/h, an output pressure of 0.1-2.5MPa, and a ratio accuracy of ± 0.05%, ± 0.5%, ± 1.5%, ± 2.5%, ± 3%.
