Flame-proof fitting for explosive pressure spaces - has non-aligned coupling apertures, and flow duct as transverse bore of large dia.

摘要

The flameproof fitting has a housing, whose two connecting holes are linked by a flow duct with a min. safety section in one part to prevent flame flash through. The connecting holes (4', 5') are mutually offset, and the flow duct consists of a bore (3) of considerably larger dia. than the holes to take a cylindrical body insert (9), whose dia. is less than that of the bore by the amount of a safety cross section. USE/ADVANTAGE - For explosion and fire prevention, excluding dirt deposition in the safety section.
