A trapezoidal cylinder induction generator vertical to the flow direction of a measured medium is placed in a meter shell, magnetic steel at the downstream of the induction generator generates a strong magnetic field, magnetic lines of force pass through a pipeline, when the medium flows through the induction generator, two lines of the medium are alternately separated and released at the two sides of the downstream of the induction generator to be processed in a staggered mode, electromotive force with the same frequency is induced by cutting the magnetic lines of force, and the separation frequency of fluid is directly proportional to flow rate when an electrode detects an electric signal in a certain speed range. High-frequency oscillation signals are input to the electrode degree at the downstream of the induction generator, the signals are modulated by induction frequency, the modulated high-frequency signals enter a detector singlechip to be operated and processed, flow signals are accurately detected, and the flow signals are input to a display singlechip to be operated and processed.
The electromagnetic flow meters of the same type commonly used in the current market have the defects of low compressive strength, unreasonable structural design, low reliability and the like. Because of the restriction of market demand, general manufacturers all adopt welded type structural design to the flowmeter body, and electromagnetic flowmeter's casing is non-solid structure, its lateral wall also is hollow structure, set up 3 coils in the hollow structure of lateral wall, realize electromagnetic flowmeter's work, and flange and annex on the electromagnetic flowmeter body (casing) all connect through argon arc welding's mode, withstand voltage of the reason body of because technology is generally no more than 6.3MPa, and the reliability of welding itself also can not satisfy the requirement, lead to product quality unstable.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to the problem that exists among the prior art, the utility model provides a novel anti high-voltage electromagnetic flowmeter has solved the withstand voltage of electromagnetic flowmeter product body not high, unstable scheduling problem of quality.
The technical scheme is as follows: the utility model provides a novel anti high pressure electromagnetic flowmeter, including casing, measurement conversion instrument, first permanent magnet and a measuring electrode, the casing is inside to set up the measurement passageway, and its both ends are equipped with mounting flange, the lateral wall of casing is solid structure, and it forges the shaping as an organic whole; the measuring and converting instrument is connected in an electrode hole in the upper end of the shell, a second permanent magnet is arranged at the bottom end of the electrode hole, the measuring electrode is connected with the measuring and converting instrument through a cable, the first permanent magnet is detachably and hermetically connected in a magnetic pole hole in the lower side of the shell, the magnetic pole hole is communicated with a measuring channel in the shell, and the first permanent magnet and the second permanent magnet are opposite in position.
Further, the fixing flange and the side wall of the shell are integrally forged and formed.
Further, the first permanent magnet is connected in a magnetic pole hole below the shell in a sealing mode through a screw plug thread.
Has the advantages that:
1. the utility model discloses a whole mould forging sets up the casing lateral wall and is solid construction, will set up and change into the permanent magnet with the interior coil of casing lateral wall and set up on the lateral wall of casing, has improved electromagnetic flowmeter body structure, guarantees that the flowmeter can bear the highest 50 MPa's high pressure, so improve product quality's reliability greatly because not weld simultaneously, can satisfy high pressure, high reliability's market demand.
2. The utility model discloses set mounting flange and flowmeter casing to the integrated forging shaping, further improve the compressive capacity and the reliability of product like this.
3. The utility model discloses detachable connects the permanent magnet in casing below, when containing a small amount of solid magnetic particles in the fluid, because magnetic action can adsorb around the permanent magnet, the effective through-hole that can make the flowmeter for a long time diminishes, thereby it is inaccurate to lead to the flow measurement, only need lift the plug screw together with the permanent magnet together lift off this moment, reuse high pressure water flushing flow path hole, until all wash away solid magnetic particles, install the plug screw again and the permanent magnet can, the convenience is washd the permanent magnet, the life of electromagnetic flowmeter is improved, and its measurement accuracy is more accurate.
