Explosion-proof solenoid valve is a device might ignite the
explosive gas mixture components all enclosed in a shell, the shell
can withstand any joints or structural gap housing, penetrated into
the interior of the housing flammable mixture in an internal
explosion without damage, and without lit from one external cause,
a variety of gases or vapors to form explosive environment, the
possible sparks, arcs and dangerous temperature of the components
are placed in a flameproof enclosure, flameproof enclosure so that
the inner space of the device and the surroundings apart.
Flameproof enclosure there is a gap, due to respiration and
electrical equipment gas permeation, so there may be an internal
explosive gas mixtures.
