Abstract:
A gas hood for a gas regulator comprises a housing for covering a gas regulator, an opening for receiving the gas regulator and semi-sealing the space between the housing and the gas regulator, and a gas inlet for constantly introducing gas into the space, wherein parts of the gas escapes from the opening so that the space can maintain a micro-positive pressure.
