Pole pipe for electromagnetic adjusting device, has four wrench surface pairs arranged at outer circumference of pipe and inserted by deforming via deforming tool, where pipe is made of ferromagnetic material

摘要

The pipe (2) has four wrench surface pairs (15) arranged at an outer circumference of the pipe and inserted by deforming via a deforming tool, where the pipe is made of ferromagnetic material. A ring (11) is made of non-ferromagnetic material, coupled in an anchor (3) in an area of a magnetic field of an actuator and provided in a longitudinal direction of a center section. An external thread (12) is provided in an area of a left end and fixes the pipe at a valve block. A ring seal (14) is provided between the thread and an annular collar (13) for sealing in relation to the valve block. Independent claims are also included for the following: (1) an electromagnetic adjusting device with an anchor adjustable by an electromagnetic actuator (2) a method for manufacturing a pole pipe.
