Protective housing in the explosion protection type flameproof enclosure

摘要

According to the invention, a protective housing (10) in the explosion-proof type of pressure-resistant encapsulation is created. At least one device (19, 36, 38, 39) for reducing explosion pressure is preferably assigned to the housing (10). The housing (10) has a first housing part (11) with a first sealing surface (13) and a second housing part (12) with a second sealing surface (14), wherein - in the pressure-tight closed state of the housing (10) - an elastic seal (32) is held elastically deformed between the first sealing surface (13) and the second sealing surface (14) and thereby the space (26) between the first sealing surface (13) and the second sealing surface (14) in the event of an explosion inside the housing (10) closes flameproof. The flameproof arrangement according to the invention can replace a flat gap between, for example, a surface of a cover and a surface of a housing part, which gap requires compliance with relatively narrow manufacturing tolerances.
