basic information
● In the case of a general flow regulator When gas at atmospheric pressure is compressed to prevent heat from escaping to the outside, it becomes high-pressure gas, and the temperature of the gas itself rises. This is called adiabatic compression. Generally, if high-pressure oxygen is suddenly introduced into the regulator, the interior of the regulator becomes high temperature due to the same phenomenon. (For example, if 14.7 MPa of oxygen is suddenly introduced, the temperature inside the regulator, which was 20°C, rises to 954°C). If there are dust, aluminum powder, oil, etc., inside the regulator at this time, they can become ignition sources or combustible materials, leading to the risk of explosion or ignition of the regulator. Conditions necessary for ignition: ignition source, oxygen, combustible material ● In the case of the New SAFETY gauge-less regulator with adiabatic compression prevention mechanism In a general regulator, when oxygen enters from the valve, it quickly reaches the pressure reduction section. The New SAFETY gauge-less regulator with an adiabatic compression heat generation prevention device is equipped with a mechanism at the oxygen inlet of the regulator that temporarily receives the oxygen even if it enters rapidly from the valve, preventing a sudden influx of oxygen. This structure keeps the heat generated by adiabatic compression low, thereby reducing the possibility of explosion or ignition due to adiabatic compression.
Applications/Examples of results
The oxygen regulator reduces explosions and ignition caused by adiabatic compression. Additionally, there is no worry about damaging the pressure gauge, making it ideal for on-site use.
Company information
Since its founding in 1918 (Taisho 7), Koike has served as an opinion leader in machine tools utilizing "gas energy," contributing to the development of key industries. During this time, in line with the progress of the era, we have developed cutting machines utilizing "plasma" and "laser" ahead of others, and have commercialized advanced automated systems using NC technology. At the same time, we have established a comprehensive total system to meet all customer needs, ranging from "gas, welding, and cutting to related equipment."
