Abstract
The utility model discloses an electromagnetic flow transducer with electrodes sealed in a multi-stage mode. The electromagnetic flow transducer comprises the two electrodes, a guide pipe, an exciting coil and an outer shell, wherein a lining used for insulation is installed on an inner ring of the guide pipe, the two electrodes penetrate through the guide pipe and the lining and are installed on electrode holes of the guide pipe, and the two electrodes are symmetrically installed relative to the axis of the guide pipe. The exciting coil is perpendicular to the electrodes and is installed between the outer shell and the guide pipe, and sealing devices are installed between the electrodes and the walls of the electrode holes of the guide pipe. The electromagnetic flow transducer with the electrodes sealed in the multi-stage mode has the advantages of resolving the problems that a common electromagnetic flow transducer is sealed only in the mode that tool faces of the electrodes are embedded in the surface of the lining and is not resistant to high voltage, so that the electrodes are prone to leakage. The electromagnetic flow transducer with the electrodes sealed in the multi-stage mode is simple in structure, guarantees permanent and normal work, and does not increase too much cost.

Utility model content
The utility model is in order to address the above problem, provide a kind of electrode simple in structure to there is the electromagnetic flow transducer of multi-stage sealed form, the electrode of this electromagnetic flow transducer not only has electrode knife face seal form, also adopt multistage electro-insulating rubber circle seal form, both increase the high-voltage resistance capability of electromagnetic flow transducer, extended greatly again the serviceable life of electromagnetic flow transducer.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of electrode has the electromagnetic flow transducer of multi-stage sealed form, comprise two electrodes, conduit, field coil, shell, at described conduit inner ring, the lining for insulating is installed, and two described electrodes are through conduit and lining, be arranged on the electrode hole of conduit, and two electrodes are installed with respect to the axis symmetry of conduit; Described field coil is arranged between shell and conduit perpendicular to electrode, between the electrode hole wall of electrode and conduit, packoff is installed.
Be provided with knife face sealing surface at described electrode tip, and knife face embeds liner surface.
Described packoff, comprise insulation sleeve I, insulation sleeve II, insulation sleeve III and o RunddichtringO I, o RunddichtringO II, insulation sleeve I, insulation sleeve II, insulation sleeve III are installed successively on the vertical direction between electrode and electrode hole wall, in the middle of described insulation sleeve I, insulation sleeve II, o RunddichtringO I are installed, at insulation sleeve II, insulation sleeve III, o RunddichtringO II are installed.
The two ends outer wall of described conduit is provided with outside flange, and in the middle of it, outer wall is provided with inner flange, and shell is welded on the inner flange of conduit.
Described electrode tip is provided with the nut that insulation sleeve I, insulation sleeve II, insulation sleeve III are locked.
Described catheter interior is equipped with lining, reaches insulation effect; Described field coil is positioned at shell and conduit, for generation of magnetic field.
Described electrode is arranged on catheter electrode hole, is used for measuring fluid the produced induction electromotive force that moves in magnetic field.
Electrode, also with knife face sealing surface, can face embedding liner surface play sealing effectiveness.
Described electrode seals, is made up of insulation sleeve and O-ring seals, between electrode hole wall and electrode, plays the effect of sealing and insulation.
Because insulation sleeve adopts PTFE, to make hardness ratio larger, and upper and lower two insulation sleeves are under the effect of check nut, and the O type rubber ring in the middle of extruding, reaches sealing effectiveness, thereby make electromagnetic flow transducer both high pressure resistant, has extended greatly serviceable life again.
The beneficial effects of the utility model are:
Having solved common electromagnetic flow transducer only relies on electrode knife face to embed liner surface to seal and not high pressure resistant, easily cause electrode to go out the problems such as leakage; This utility model is simple in structure, in having ensured the permanent normal work of electromagnetic flow transducer, also can not increase too many cost.
