摘要

The pipe disconnector has a housing (1, 12) with an intake, an outlet (8) and a drain (13) for a liquid. In an operating condition of the flow, the intake with the discharge is hydraulically connected and the drain locked. In an operating condition of the separation the connection between the intake and the outlet (8) is interrupted and the drain is opened to partially empty the housing.
