Manual fire extinguisher with container and hose

摘要

The container (27) and protective casing (17a) are threaded at their respective top (27) or bottom (17a) ends in sleeve form (29) as screwed into the respective container or casing openings and the rupture disc (34) is exchangeably contained in a bung (30) to be fitted into the threaded sleeve (29). The opening for the sleeve forms part of a closure (22) at the bottom end (17a) of the casing (17) and is internally threaded to engage the outside thread of the container (27) neck sleeve (29), or vice versa. The opening is enclosed by a shoulder (26) as adjoined by the forward end of the bung (30). The bung itself has a shoulder-limited (33) disc (34) opening and the sealing ring (35) of the disc bears on the shoulder (26). The end of the bung (30) projecting from the sleeve (29) is expanded in flange form and is divided from the sleeve by a sealing ring (31). The bottom end of the sleeve (17a) and the top of the container (27) adjoin one another via concave or convex contour s. Another rupture disc can be fitted at the bottom end of the container and is here held releasably in place by a nut.
