Valve - Wikipedia

A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.Valves are technically fittings, but are usually discussed as a separate category.In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Inert gas - Wikipedia

An inert gas is a gas that does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and ...

Oil for Vacuum Pumps

Jan 14, 2015·Cylinders containing different gases may be processed on the same filling system so there is a chance that oxygen gas may enter the vacuum pump on the system. Consequently, the standard vacuum pump fluid used by most gas cylinder companies was a fire “retardant” phosphate ester fluid. This fluid was not completely inflammable.

Air–fuel ratio - Wikipedia

Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon).. The air-fuel ratio determines whether a mixture is ...
