Ventil zur Zwei- oder Mehrwegeströmungsregulierung

摘要

A valve for a two-way or multiple-way flow regulation is provided with a valve spindle (9), mounted in a valve housing (5), on which spindle a first valve body (22) is mounted and designed to regulate large flows in relation to a valve seat (19), attached to the housing, between an inlet (14) and an outlet (15). Said valve body (22) forms a seat (51) for a second valve body (37), designed to regulate small flows. According to the invention the second valve body is formed by the free spindle end at its entry into a bore (27) through the first valve body, whereas the spindle end, which exists at the other side of this valve body, supports a stop element (28), which is designed to lift the first valve body from its seat (19), when the spindle is retracted/lifted, to allow a spindle movement beyond the closing position for this body and to choke the flow through the second valve in the final phase of its opening movement.
