Abstract
The utility model relates to a kind of underground internal magnet type electromagnetic flowmeter electrode special seal and pressure bearing structures, it is column structure, innermost layer is electrode, and the electrode exterior is followed successively by electrode fastener, elastic washer, gasket, felt pad and gum cover from top to bottom, and gasket edge is wrapped up in the felt pad periphery；Electrode fastener, elastic washer, gasket and felt pad outer layer are equipped with pressure part, and the pressure part is located above gum cover.The utility model has the advantages that radial dimension is small, the pressure bearing and seal of narrow dimension structure, high reliablity are adapted to.
Description
Technical field
The utility model belongs to electrode bearing structure, and in particular to a kind of underground internal magnet type electromagnetic flowmeter electrode special is close
Seal bearing structure.
Background technique
Due to space limitations, internal magnet type electromagnetic flow meter electrode seal and pressure bearing structure can not do tapered pressure bearing and seal knot
Structure, and conventional pressure-balancing type sealing structure high failure rate in use, maintenance get up it is particularly troublesome, and due to interior external pressure
Balanced design must be filled with the silicone oil of balance external and internal pressure in instrument, the length of instrument virtually be increased, by a large amount of formula
Sample, the application (underground internal magnet type electromagnetic flowmeter electrode special seal and pressure bearing structure) solve the above problem substantially.
Utility model content
The purpose of this utility model is to solve the above problems, and it is close to provide a kind of underground internal magnet type electromagnetic flowmeter electrode special
Bearing structure is sealed, radial dimension is small, adapts to the pressure bearing and seal of narrow dimension structure, high reliablity.
To achieve the above object, the utility model provides the following technical solutions:
A kind of underground internal magnet type electromagnetic flowmeter electrode special seal and pressure bearing structure, is column structure, and innermost layer is electricity
Pole, the electrode exterior are followed successively by electrode fastener, elastic washer, gasket, felt pad and gum cover, the felt pad from top to bottom
Periphery package gasket edge；Electrode fastener, elastic washer, gasket and felt pad outer layer are equipped with pressure part outermost layer as electrode peace
Seat is filled, the pressure part is located above gum cover.
Further, the electrode fastener is fastening nut, and the pressure part is pressure-bearing nut.
Further, the gum cover is fluorine gum cover.
Further, described bearing structure each section is all made of screw thread and is installed.
Further, the bearing structure is suitable for the pressure bearing and seal of narrow dimension structure.
The utility model has the beneficial effects that:
It is verified compared with existing inside and outside pressure balance type structure, and by a large amount of field experiment, the utility model is radial
Size is small, adapts to the pressure bearing and seal of narrow dimension structure, and failure rate is low, high reliablity, easy to maintain, and the service life is longer.
Detailed description of the invention

Specific embodiment
A kind of underground internal magnet type electromagnetic flowmeter electrode special seal and pressure bearing structure as shown in Figs. 1-3 is cylinder knot
Structure, innermost layer are electrode 1, are followed successively by electrode fastener 2, elastic washer 3, gasket 4, insulation outside the electrode 1 from top to bottom
Pad 5 and gum cover 6,5 periphery package 4 edge of gasket of felt pad；Electrode fastener 2, elastic washer 3, gasket 4 and felt pad 5
Outer layer is equipped with pressure part 7, and the pressure part 7 is located at 6 top of gum cover.
Further, the electrode fastener 2 is fastening nut, and the pressure part 7 is pressure-bearing nut.
Further, the gum cover 6 is fluorine gum cover.
Further, described bearing structure each section is all made of screw thread and is installed.
Further, the bearing structure is suitable for the pressure bearing and seal of narrow dimension structure.
It is verified compared with existing inside and outside pressure balance type structure, and by a large amount of field experiment, the utility model is radial
Size is small, only 18mm, adapts to the pressure bearing and seal of narrow dimension structure, and failure rate is low, high reliablity, easy to maintain, and uses
Longer life expectancy.
The content not being described in detail in the utility model is the prior art.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
