Description
(1) Technical field [0001] The invention relates to a gas mixing device, in particular to a Roots gas mixing device. (2) Background technology [0002] In industrial production, it is often necessary to mix two gases for use. For example, in the gas industry, liquefied gas and air are mixed to form liquefied gas mixed with air to replace natural gas; nitrogen and argon are mixed for gas protection gas; Using natural gas mixed with special agents to form modern shipbuilding cuts. At present, there are many kinds of devices for mixing two gases, but there are some problems, such as complex structure, high cost, poor safety, inaccurate measurement or difficult operation, etc. In particular, a simple and practical device is needed to accurately mix gas. (3) Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a Roots gas mixing device, which is simple in structure, easy to implement, low in cost, economical and app...
