Description

Ceramic coatings electrode
Technical field
The utility model relates to fluid flowmeter fields, more particularly to a kind of ceramic coatings electrode.
Background technique
Slurries high-voltage electromagnetic flowmeter is flow measurement instrument, as in traffic monitoring, mistake range of flow, flow measurement measurement It is widely adopted.The principle of electromagnet flow meter sensor is Faraday's electromagnetic induction law;Conducting liquid flows production in magnetic field Raw induced electromotive force.
The conducting liquid for flowing through operating fields is measuring one of mutually perpendicular direction between tube wall and flow direction and magnetic field The electromotive force proportional to volume flow between generation electrode.Containing the uneven solid particles of media such as silt, coal slurry, corrosion In the case where conducting liquid, requirement of the medium to the abrasion of electrode, adhesion, attachment, burn into electrochemical reaction etc. is had occurred Variation, increases the factors such as loss and the flow measurement inaccuracy of signal.
Utility model content
For above situation, for the defect for overcoming the prior art, the utility model provides a kind of ceramic coatings electrode, solves Conducting liquid containing solid particle and fibrous matter easily generates friction and corrosion to electrode in flowing, and to electrode surface Chemoproection film leads to the problem of destruction.
Its technical solution is ceramic coatings electrode, the electrode tip including cylindrical structure, and the electrode tip removably connects It is connected to electrode stem, the one end diameter of the electrode tip reduces the fixed part to be formed for connection electrode bar, the electrode stem End offers fixing groove compatible with the fixed part inwardly, is equipped with internal screw thread, the fixation inside the fixing groove Portion is equipped with external screw thread compatible with the fixing groove, and the fixed part is threadedly coupled with the fixing groove, the electricity The junction of cartridge and the electrode stem is generally aligned in the same plane, and the end face of the electrode tip and protrusion are coated with ceramics and receive The end of rice material, the electrode stem and the electrode tip connecting pin is coated with ceramic nano material.
Further, the middle position of the electrode stem is equipped with the fixed part perpendicular to the electrode club shaft, institute The connecting pin of electrode stem and the electrode tip is stated to being coated with ceramic nano material between the fixed part.
The utility model has the technical effect that the electrode tip and the electrode stem are coated with ceramic nano material, and ceramics are received Rice material can be by the metal portion of the grease contained in liquid, fixed particle, corrosive media and fibrous matter and electrode interior Divide and be effectively isolated, avoids friction, the corruption to electrode surface such as solid particulate matter, fibrous matter in measurement liquid Erosion, pollution, adhesion, attachment are further reduced the damage to electrode surface chemoproection film, and ceramic coatings electrode tip length can root It is selected according to liner thickness, electrode tip protrusion part can keep smooth consistent with measurement inner wall, avoid particulate matter medium to electrode Shock and attachment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of electrode tip in the utility model.
Fig. 2 is the structural schematic diagram of electrode stem in the utility model.
Fig. 3 is the structural schematic diagram that electrode tip is combined with electrode stem in the utility model.
Specific embodiment
Below in conjunction with Figure of description, specific embodiment is described in further details.
Electrode tip 1: the electrode tip 1 forms cylindrical structure, and the one end diameter of the electrode tip 1 reduces to form cylinder The fixed part 4 of body structure, the fixed part 4 are equipped with external screw thread, and the end face of the electrode tip 1 and protrusion subpackage are covered with pottery Porcelain coating.
Electrode stem 2: the end that the electrode stem 2 is connect with the electrode tip 1 is recessed inwardly to be formed and the fixed part 4 The inside of compatible fixing groove 3, the fixing groove 3 forms the most compatible external screw thread of the fixed part 4, the electrode tip 1 It is threadedly coupled by the fixing groove 3 with the fixed part 4 with the electrode stem 2, the electrode tip 1 protrudes above part Diameter is identical as the diameter of 2 body of rod of electrode stem, the electrode tip 1 and the electrode stem 2 by the fixing groove 3 with it is described Fixed part 4 realizes smooth and seamless connection, and the junction of the electrode tip 1 and the electrode stem 2 is in the same plane, the electricity The middle position of pole bar 2 is equipped with the fixed part perpendicular to 2 body of rod of electrode stem, the electrode stem 2 and the electrode tip 2 Connecting pin is to being coated with ceramic material between the fixed part, the girth weld of the electrode stem 2 and 1 joint surface of electrode tip There are 2-3 solder joints, each pad surface is smoothly without protrusion, and each solder joint does not destroy the complete of ceramic coating and cleaning.
Suitable ceramic coating electrode tip and ceramic coating can be selected according to the thickness of measurement lining in anabolic process Electrode stem be combined, make the protrusion part of electrode tip 1 with measurement lining be maintained on same smooth surface, and slightly protrusion survey Liner surface 0.5-1mm is measured, shock and attachment of the particulate matter and fibrous matter in measurement liquid to electrode tip is avoided, measures liquid Body can smoothly take away attachment during flowing.
The ceramic coating coated on the electrode tip 1 and the electrode stem 2 is ceramic nano material, ceramic nano material tool Body can be for nanoscale ceramic particle, whisker or fiber etc., the ceramic nano material of cladding and the oil that can will contain in liquid Rouge, fixed particle, corrosive media and fibrous matter are effectively isolated with the metal part of electrode interior, avoid measurement Friction, the burn into pollution, adhesion, attachment to electrode surface such as solid particulate matter, fibrous matter in liquid, is further reduced Damage to electrode surface chemoproection film enhances the C-V characteristic of electrode, avoids the electrochemistry of fluid media (medium) and electrode Reaction, the signal for exporting electromagnetic flowmeter are more reliable and more stable.
The utility model has the technical effect that the electrode tip and the electrode stem are coated with ceramic nano material, and ceramics are received Rice material can be by the metal portion of the grease contained in liquid, fixed particle, corrosive media and fibrous matter and electrode interior Divide and be effectively isolated, avoids friction, the corruption to electrode surface such as solid particulate matter, fibrous matter in measurement liquid Erosion, pollution, adhesion, attachment are further reduced the damage to electrode surface chemoproection film, and ceramic coatings electrode tip length can root It is selected according to liner thickness, electrode tip protrusion part can keep smooth consistent with measurement inner wall, avoid particulate matter medium to electrode Shock and attachment.
The utility model is described in detail above by specific embodiment and embodiment, but these are not structure At limitations of the present invention.In the case where not departing from the utility model principle, those skilled in the art can also be made Many modification and improvement, these also should be regarded as the protection scope of the utility model.
