Description

A kind of electromagnetic flowmeter

Technical field

The invention belongs to flowmeter technology fields more particularly to one kind can reflect interior lining over worn electromagnetic current Meter.

Background technique

Electromagnetic flowmeter be using electromagnetic induction principle, according to conductive fluid by the electromotive force inducted when externally-applied magnetic field come A kind of instrument of measurement conductive fluid flow, has and is quick on the draw, no machinery inertial, not by the temperature of measured medium in measurement process The influence of degree, viscosity, density and conductivity, range ability is wide, and the low advantage of operation energy consumption has very in current industrial production It is widely applied.But electromagnetic flowmeter is in use, the wear condition of lining can not be found in time, only be ground When damaging flowmeter and not working, it could find that lining has worn out, usually will cause whole system at this time cannot normally transport Turn, the data obtained inaccuracy causes damages.

Summary of the invention

In order to overcome the problems, such as that lining excessive wear is not easy to be found in time in existing electromagnetic flowmeter, the present invention provides one Kind electromagnetic flowmeter, the electromagnetic flowmeter can show lining excessive wear in time, remind staff's more exchange device, it is ensured that institute Measured data is accurate.

The technical solution adopted by the present invention to solve the technical problems is: a kind of electromagnetic flowmeter, including measurement conduit and Two tubulose oil ga(u)ges, the measurement conduit two sides of the bottom are respectively provided with a through-hole, are equipped with lining, the lining in the measurement conduit In in be evenly equipped with several with lining centerline parallel pipeline, minimum range of each pipeline from lining inner surface is not more than lining The 5% of internal diameter, two sides are respectively equipped with an annulus in the lining, and minimum range of each annulus from lining inner surface is not more than The 5% of lining internal diameter, the end of all pipelines is connected to ipsilateral annulus in lining, and each annulus bottom is equipped with one and goes out The mouth of a river, ipsilateral water outlet and through-hole are concentric, and one end of two tubulose oil ga(u)ges is respectively connected with a water outlet, the pipe The shape oil ga(u)ge other end passes through through-hole and protrudes from measurement conduit outer wall.

Preferably, the mode that water outlet is connected with tubulose oil ga(u)ge are as follows: water outlet is equipped with screw thread, and tubulose oil ga(u)ge end is also set There is screw thread, the two is connected through a screw thread.

Preferably, it is equipped in the tubulose oil ga(u)ge and surveys water test paper.

After Lining wear is excessive, the pipeline in lined inner wall can be damaged, and tested quantity of fluid first flows into pipeline, then flows into circle Ring is then flowed in tubulose oil ga(u)ge by the water outlet of annulus bottom, can be by whether having liquid in observation tubulose oil ga(u)ge, to sentence Disconnected lining whether survey water test paper and meet liquid colour-changeable, can be convenient sight by excessive wear, the setting survey water test paper in tubulose oil ga(u)ge It examines.

The beneficial effects of the present invention are: electromagnetic flowmeter lining excessive wear can be found in time, to avoid grinding because of lining Measurement caused by damage is inaccurate, simple and reliable for structure.

Detailed description of the invention

The present invention is further illustrated with example with reference to the accompanying drawing.

Fig. 1 is structural schematic diagram of the invention.

Fig. 2 is cross-sectional view of the invention.

1. measurement conduit in figure, 2. linings, 3. tubulose oil ga(u)ges, 4. pipelines, 5. annulus, A. pipeline is most from lining inner surface Small distance.

Specific embodiment

In Fig. 1 and Fig. 2, a kind of electromagnetic flowmeter, wherein 1. measurement conduits, 2. linings, 3. tubulose oil ga(u)ges, 4. pipelines, 5 circles Ring.The measurement conduit two sides of the bottom are respectively provided with a through-hole, and lining is equipped in the measurement conduit, is evenly equipped in the lining Several pipelines with lining centerline parallel, minimum range (A) of each pipeline from lining inner surface are the 4% of lining internal diameter, institute It states two sides in lining and is respectively equipped with an annulus, minimum range of each annulus from lining inner surface is the 4% of lining internal diameter, lining In in the ends of all pipelines be connected to ipsilateral annulus, each annulus bottom is equipped with a water outlet, ipsilateral water outlet Mouth and through-hole are concentric, and one end of two tubulose oil ga(u)ges is respectively connected with a water outlet, and the tubulose oil ga(u)ge other end is worn It crosses through-hole and protrudes from measurement conduit outer wall.

Preferably, the mode that water outlet is connected with tubulose oil ga(u)ge in this example are as follows: water outlet is equipped with screw thread, tubulose oil ga(u)ge End also is provided with screw thread, and the two is connected through a screw thread.

Preferably, it is equipped in tubulose oil ga(u)ge described in this example and surveys water test paper.

For clarity to those skilled in the art's display technique scheme in attached drawing, thus lining interior conduit interval show compared with Greatly, pipeline enclosure guarantees that everywhere abrasion can be found in time away from very small in practice.
