Description
Technical field
The present invention relates to flow instrument fields more particularly to one kind can intuitively reflect that electromagnetic flowmeter lining is over worn
Electromagnetic flowmeter.
Background technique
Metering is industrial eyes.Flow measurement is one of the component part of measuring science technology, it and its people pass through
Ji, national defense construction, scientific research have close relationship.This work is carried out, to guarantee product quality, improves production efficiency, rush
Development into science and technology all plays an important role, especially higher and higher in energy crisis, industrial production automation degree
Current era.Electromagnetic flowmeter is a kind of flowmeter more common in industrial production, is to apply electromagnetic induction principle, according to
Conductive fluid measures a kind of instrument of conductive fluid flow by the electromotive force inducted when externally-applied magnetic field.But in the course of work
In, the abrasion of electromagnetic flowmeter lining is not easy can be visually seen, and Lining wear bring internal diameter changes, and can reduce electromagnetism
The measurement accuracy of flowmeter, when excessive wear will affect normal production work.
Summary of the invention
In order to overcome the shortcomings of that existing electromagnetic flowmeter Lining wear is excessively not easy to be observed, the present invention provides one kind
New Electromagnetic Flowmeter, this kind of New Electromagnetic Flowmeter can find that in time Lining wear is excessive.
The technical solution adopted by the present invention to solve the technical problems is: New Electromagnetic Flowmeter, including measurement pipeline
And lining, the measurement pipeline both sides are respectively equipped with a through-hole, the lining is set in measurement pipeline, and the lining is equipped with
Air inlet and air outlet, the air inlet and air outlet on the lining are respectively arranged in the through-hole on measurement pipeline, the air inlet
Check valve is equipped in mouthful, described gas outlet one end is connected with bend pipe, and the bend pipe other end is equipped with pressure gauge, sets in the bend pipe
There is water blocking yarn, helical form bend pipe is additionally provided in the lining, the minimum value of the bend pipe to lined inner wall is the critical value of abrasion,
The bend pipe both ends are connected with air inlet and air outlet respectively, and the inert gas with certain pressure is equipped in the bend pipe.
The preferred inert gas is nitrogen.
When Lining wear is to critical localisation, the gas in bend pipe can be leaked, and air pressure reduces in pipeline, can pass through gas at this time
Pressure apparently is examined out, and to prevent due to overlong time, the gas leakage that member slots generate can be filled from check valve into bend pipe
Gas, by observation air gauge, whether return judges, the water blocking yarn being equipped in bend pipe, water blocking yarn water-swellable can prevent from being tested
Quantity of fluid reflux corrosion air gauge.
The beneficial effects of the present invention are: can be observed by air gauge electromagnetic flowmeter lining whether excessive wear, simply
It is convenient.
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.
1. pressure gauge in figure, 2. water blocking yarns, 3. bend pipes, 4. gas outlets, 5. bend pipes, 6. linings, 7. measurement pipelines, 8. is unidirectional
Valve, 9. air inlets.
Specific embodiment
In Fig. 1, New Electromagnetic Flowmeter, wherein 1. pressure gauges, 2. water blocking yarns, 3. bend pipes, 4. gas outlets, 5. bend pipes, 6.
Lining, 7. measurement pipelines, 8. check valves, 9. air inlets.The measurement pipeline both sides are respectively equipped with a through-hole, and the lining is set
In in measurement pipeline, the lining is equipped with air inlet and air outlet, and the air inlet and air outlet on the lining are respectively arranged on
It measures in the through-hole on pipeline, check valve is equipped in the air inlet, described gas outlet one end is connected with bend pipe, and the bend pipe is another
One end is equipped with pressure gauge, and water blocking yarn is equipped in the bend pipe, is additionally provided with helical form bend pipe, the bend pipe to lining in the lining
The minimum value of inner wall is 10 millimeters, and the bend pipe both ends are connected with air inlet and air outlet respectively, and being equipped in the bend pipe has
The inert gas of certain pressure.
3 millimeters of bend pipe diameter in this example, screw pitch are 5 millimeters.
Inert gas is nitrogen in this example, and air pressure is 3 standard atmospheric pressures.
In order to intuitively to those skilled in the art's display technique scheme in attached drawing, therefore the screw pitch of bend pipe seems larger, practical
Middle screw pitch is very small, ensure that everywhere abrasion can be found.
