In all purification equipment, electrical tar device exploded at the same time there are only two of the three elements,
namely the gas and electric spark, it produces the possibility of explosion in running is bigger than the possibility
of other purification equipment.As we all know, often because of the air blower power outages, machine is not power,
went into a state of negative pressure gas purification system at this time, to cut off the water seal in the inland
waters by absorption, water seal damage, air from water drain suction and enter electrical tar is full of gas, the three
elements exist and explosion.Have a plenty of send gas again, in the first sending cases also can appear the explosion
accident, so electrical tar instrument jacket in explosion-proof valve completely necessary, and it is very practical.
Explosion-proof electrical tar of valve generally has two forms, the vertical and horizontal explosion-proof valve type
explosion-proof valve, both explosion-proof valve is to use explosion-proof membrane sealed structure, vertical type
explosion-proof valve is installed on the cylinder, and horizontal explosion-proof valve is installed on the top of
the tower.
Because of explosion-proof valve in normal work, need to support bar will cover jacking, so conducive to blast pressure,
and after pressure relief, and cover must be closed immediately, to prevent secondary explosions, also some units
use explosion-proof valve out of no cover on the explosion-proof membrane in a rubber cover, then use of flat spherical
cross shield. |
