Description

Technical Field

The utility model relates to an electrode 4 technical field, in particular to high pressure toper electrode structure.

Background

The electromagnetic flowmeter is widely applied to sewage, petrochemical industry, production water, tap water industry, medicine, steel and other aspects. Along with the improvement of the industrial automation level, the electromagnetic flowmeter is more and more adopted in various production fields, and meanwhile, the electromagnetic flowmeter is also adapted to different working condition environments, and new requirements on corrosion resistance, high temperature resistance and the like are provided.

At present, the pressure resistance of an electromagnetic flowmeter is too low, the electromagnetic flowmeter cannot be used under the conditions of high pressure and ultrahigh pressure, particularly, the pressure resistance of the electromagnetic flowmeter is generally not more than 10MPa when the electromagnetic flowmeter is used for high-pressure water injection in an oil field, and the installation mode and the structural sealing of electrodes always are huge bottlenecks which disturb the electromagnetic flowmeter. Particularly, the electrodes in the prior art are basically straight-barrel external-insertion type electrodes and are filled and sealed by using sealing materials such as sealing glue, and the like, so that the pressure resistance of the electrodes is restricted due to the limitation of structural forms and the limitation of sealing modes, and the electrodes cannot bear the application of corrosive high-pressure environment under the conditions of strong corrosive environment, high pressure and ultrahigh pressure states of strong acid, strong alkali and the like.

However, in order to improve the pressure resistance, the bottleneck that the electromagnetic flowmeter cannot be used under the high-pressure and ultrahigh-pressure states is overcome. The tightness between the electrode and the measuring catheter must be improved, but if the measuring catheter and the electrode adopt the existing structure in the prior art, the leakage phenomenon occurs at the electrode under the high-pressure and ultrahigh-pressure states, and the tightness is poor. And because the electrode is sintered, so the pressure resistance of the joint point is not strong due to the difference of materials, the sealing performance is not good, and the joint point cannot be used, so the safety coefficient is low, and the joint point cannot be detected well during detection.

A high voltage tapered electrode structure is needed to address this problem.

SUMMERY OF THE UTILITY MODEL

In view of the above situation, in order to overcome the defects of the prior art, the present invention aims to provide a high-voltage tapered electrode structure, which effectively solves the above problems.

The technical proposal for solving the problem is that the utility model comprises a tube body, an inner liner is attached to the inner wall of the tube body, an electrode holder is arranged on the tube body, an electrode connected on the inner liner is arranged on the electrode holder, and the electrode is connected with the electrode holder through a pressing cap;

the electrode is conical, one end of the electrode, which extends into the lining layer, is a conductive part, the other end of the electrode is provided with an annular groove, a sealing cover is arranged on the annular groove, and a sealing ring is arranged between the annular groove and the sealing cover.
