Description
Technical field
The present invention is the corresponding improvement with the high-field electrode structure on high-voltage electromagnetic flowmeter.
Background technology
At present, electromagnetic flowmeter has turned into a kind of maximum flow instrument of dosage, and high-voltage electromagnetic flowmeter is then wherein
Critically important one kind.But at the scene during use, the problem of its is maximum is the dielectric strength and sealing problem of high-field electrode.It is existing
Field is in use, because the pressure for measuring pipeline inner high voltage fluid is generally PN16MPa or PN25MPa, sometimes even up to
PN32MPa or PN42Mpa.Its sealing structure is that high-field electrode is a tapered rod structure, inserts between electromagnetic flowmeter lining, leans on
Single sealing is realized between the taper and electromagnetic flowmeter lining of high-field electrode.Its dielectric strength and sealing are to rely on high-tension electricity magnetic current
Interference fit between the elasticity and high-tension electricity pole bar of material of gauge lining itself seals to produce, and passes through the tight of outer locking nut
Gu power, make to produce axial seal between the bottom surface of high-field electrode bottom and high-tension electricity magnetic flowmeter liner.
This sealing structure, it is that high-tension electricity magnetic flowmeter liner and its material are played into insulating effect in itself, shortcoming is, its
Material it is elastic poor, deformation is smaller, under operating on low voltage state still, under high-pressure work state, then poor-performing；Especially
It is under high-pressure work state, pressurization, pressure release, are also easy to produce Fatigue Deformation, follow the string, so as to produce seal failure, make repeatedly
Into the leakage of fluid；And with measuring catheter contact, make electrode and measurement conduit UNICOM, so that the dielectric strength of electrode declines,
Make caused measurement signal on electrode suddenly big or suddenly small, it is multifarious to work.What is more, if pressure is excessive, or sealing surface is broken
It is bad serious, it may appear that detected fluid is with pressure to leak, and breaks through shell body, causes the destruction of working site or the people of field personnel
Body injures, and serious field accident occurs.
The content of the invention
The present invention is to overcome technical problem existing for above-mentioned prior art, there is provided a kind of improved safe and reliable, structure letter
High-field electrode structure that is single, being readily produced.
A kind of high-field electrode structure of high-voltage electromagnetic flowmeter, it is characterised in that high-field electrode is crossed cylinder shape, cross
Shape end set has a screwed hole；At least provided with a circle high pressure sealing loop material on circumference in the middle part of cross；In the middle part of cross
At least provided with a circle high pressure sealing loop material on bottom surface；At least provided with a circle high pressure sealing loop material on criss-cross bar portion circumference
Material.
The high-field electrode of the present invention employs multiple high pressure compound sealing structure.First layer high pressure sealing and second layer high pressure
Sealing is high-field electrode bar portion dual piston sealing structure, and third layer high pressure sealing is high-field electrode bottom surface axial seal structure,
4th floor height means of press seals is piston sealing structure in the middle part of electrode, shares four high pressure seal structures.
The present invention in practicality, when pressurized fluid in a high voltage state, even if after first layer high pressure sealing is broken, its flow
Body institute band pressure also will significantly decay, substantially to next road sealing device without surge, along with the also the 3rd,
4th high pressure seal structure, so as to which the dielectric strength of high-field electrode and sealing problem be completely secured, ensure high-tension electricity magnetic current
The normal work and accuracy of gauge, and security.
The advantage of the invention is that：Multiple high densifier is employed, so that high-voltage electromagnetic flowmeter uses at the scene
When, can completely effectively solve high-field electrode dielectric strength in a high voltage state and sealing problem, so as to ensure high-tension electricity
The normal work and accuracy and security of magnetic flowmeter.The purpose of the present invention is reached.
