Means for attaching a standpipe to an underground hydrant

摘要

A one-part housing (10) has a central shut-off part (5) and several outlets (9), which are separated by a system divider. This consists of a securing cartridge (7) on the intake side, and a back pressure valve (8) on the outlet side. The outlets are positioned in a ring around the back pressure valve and connected to it via ring chamber (3). All components are enclosed by a protective basket (10a). Basket, cartridge, and valve are accessible from above for maintenance purposes. The basket is fastened non-turnable to the stand pipe (4) and has a turning ring (12) to fasten the pipe to the hydrant.
