RECEPTION DETAIL couplings for pipelines FLUID MEDIUM

摘要

1. The receiving part (1) for coupling a fluid conduit which is adapted for receiving and fixing the insert part (2) in the closed position, it being connected to the receiving part (1) with an electric resonant circuit coil (5) which in the closed position the insert part (2) during the approach of electromagnetic energy is made to oscillate with a certain corresponding characteristic frequency circuit resonant frequency, the resonant circuit constantly closed, and there being a setting device which interacts with a resonant circuit without contact, and with the insert part (2) mechanically so that the resonant circuit when different from the closed position intermediate position the insert part (2) is different from the characteristic frequency of the resonant frequency circuit, and in the closed position, - the characteristic circuit frequency, the adjustment device acts on the inductance of an electrical resonance circuit, characterized in that has an impact part (6) which when inserting the insert part (2) into the receiving part (1) mechanically acts on the coil (5) so that the shape of the coil (5) in the closed position is different from the shape of the coil (5) in the intermediate position .2. The receiving part (1) according to claim. 1, characterized in that the coil (5) in the closed position has a length which is different from the length of the coil (5) in the intermediate polozhenii.3. The receiving part (1) according to claim. 2, characterized in that the acting part is formed in the form of a press slide (6) which is inserted in the insert part (2) into the receiving part (1) slides on the receiving rods
