摘要

The device (100) has two auxiliary device segments (110.1, 110.2, 120.1, 120.2) joined together by a connection part (9) and auxiliary device parts (110, 120) joined together by another connection part (10). One auxiliary device part comprises a recess from outside on a side of intermediate flanges (6b) remaining at a valve housing. The other auxiliary device part comprises a recess on a side of the intermediate flanges not remaining at the valve housing, related to a tube axis (R) axial from the outside in a diameter-reduced region. The connection part is a hexagonal transit screw and hexagon nut.
