The 20-inch manhole cover is a special manhole cover for foreign trade export. The manhole cover is
installed on the top of the tank truck and has built-in breathing and emergency exhaust functions;
during the oil transportation process, the internal breathing valve keeps the pressure inside and
outside the tank balanced; When the pressure in the tank rises sharply, the emergency exhaust
device will automatically open to release the internal pressure. Even in the event of an accident, the
anti-overflow device of the breathing valve can still remain sealed to prevent accidents.
