EINFÜHRWERKZEUG IN EINE HÜLSE EINER DURCHFLUSSSTEUERVORRICHTUNG FÜR FLÜSSIGKEITSKANALISATION UND UMSETZUNGSVERFAHREN

摘要

The tool has an ejecting button (32) mounted slindingly with respect to a bush (31) for partially ejecting a flow control device. A centering piston (52) is slid in a cylinder (51), where the piston is solicited elastically by a prestressed spring (53) towards a rest position. An input funnel receives the bush, and an output funnel is dimensioned for partially receiving a sheath (2) and being introduced in the cylinder. A radial shrinkage zone connects the input funnel and output funnel, where the zone includes a section that is equal to an internal section of the sheath. An independent claim is also included for a method for introducing a flow control device in a sheath.
