There are several types of acetylene pressure gauges: single-stage, two-stage, and pressure gauges with flow meters. The single-stage pressure reducing gauge has a relatively simple structure with only one pressure reducing chamber device, which can reduce the pressure of high-pressure acetylene gas to the required working pressure at once. Its characteristic is low cost, but the stability of pressure reduction is slightly poor, and the output pressure is relatively affected by changes in input pressure and brightness force.
2. The two-stage pressure reducing gauge is equipped with a two-stage pressure reducing device, and the gas first undergoes a first stage rough pressure reduction, and then passes through a second stage fine pressure reduction. Its core advantage is the ability to provide a more stable output pressure, which is less affected by input pressure fluctuations, making it more suitable for welding or cutting applications that require high pressure stability. 3. The pressure reducing gauge with flow meter integrates flow measurement function on the basic pressure reducing function, which can intuitively display the real-time usage flow of acetylene gas. This feature makes it widely used in the work of accurately controlling gas consumption based on the required chain width, making it easy for users to grasp and manage gas consumption.
