Pneumatic valves at low temperature on the material and structural requirements for fire and explosion prevention

in the working medium of hydrogen and oxygen medium pneumatic valve has the certain fire prevention organ, known as oxygen is a strong oxidizer, many metal materials and nonmetal materials can burn in the presence of oxygen. Pressure and temperature. Burning in oxygen medium will cause serious consequences, so tired, the door structure shall conform to the - — Set of requirements. Pure hydrogen and the creation of combination of pneumatic valve material not yet cause dangerous middle office have air or sealed to form explosive mixture. Ivanov has studied to ensure the prevention of sexual problems. Under his leadership, set to work in policy in the medium of the basic requirements of equipment.
from the viewpoint of pneumatic valve explosion-proof requirements including the structure of the requirements for the assembly and the requirements for correct selection of materials about two parts. Ivanov to taking the material can work in oxygen medium is divided into the following three categories. The probability of A class A in oxygen combustion rock: JiDing conditions almost micro to don't have to consider the material, the actual L in less oxygen is as materials. YanLi material loss, the line section is still closed. Under the condition of contact with the oxygen allows you to use, and have been confirmed through the practice of the material.
