AI Technical Summary
Technical Problem
Existing gas dilution devices are not suitable for sampled gases stored in gas bags, are cumbersome to operate and have low accuracy, and cannot achieve rapid and accurate dilution.
Method used
A standard dilution device for gas analysis was designed, including a dilution cylinder, a piston, a piston rod, intake ports of unequal diameter, and a control valve. The flow ratio is calculated by a limit adjustment structure and Bernoulli's equation to achieve precise control and mixing of the sample gas and the dilution gas.
Benefits of technology
It enables rapid and accurate dilution of sample gas and dilution gas, is simple to operate, reduces production costs, and improves the accuracy of the dilution process.

Abstract
The utility model discloses a standard dilution device for gas analysis, which comprises a dilution cylinder with an opening at the upper end, a piston is slidably mounted in the dilution cylinder in a sealed manner and connected with a piston rod, the piston rod extends out of the opening at the upper end of the dilution cylinder, and a gas outlet pipe orifice is arranged at the bottom of the dilution cylinder. A first air suction pipe opening and a second air suction pipe opening are symmetrically formed in the side wall of the lower end of the dilution cylinder, the inner diameter of the first air suction pipe opening is unequal to that of the second air suction pipe opening, an observation window is formed in the dilution cylinder, and scale marks for displaying the position of the piston are arranged on the observation window. A first air suction control valve and a second air suction control valve are detachably installed on the first air suction pipe opening and the second air suction pipe opening respectively, an air outlet control valve is detachably connected to the air outlet pipe opening, and a limiting adjusting structure for adjusting the movement limit position of the piston is further arranged at the opening of the upper end of the dilution barrel. The standard dilution device can quickly and accurately dilute the sampled gas, and is simpler to operate.
