Description
Technical field
This utility model relates to instrument and meter for automation field, is specifically related to a kind of wear-resisting type wedge flow meter.
Background technology
Wedge flow meter is applied widely.It is applicable not only to monophasic fluid, is also applied for gas-liquid, gas-solid and the two-phase such as liquid-solid
Fluid, its Reynolds number minimum reaches 300, reaches as high as 1 × 106, so wedge flow meter both can be operated in laminar condition, also
Turbulent condition can be operated in.Wedge flow meter without deposition, do not block, be applicable to high temperature, high pressure, high viscosity, deep-etching each
Plant liquid or the flow measurement of gas.There is no any effusion meter up to now to compare favourably therewith.At coal chemical industry, Heisui River buck
In containing sulfur dioxide, it necessarily generates sulfurous acid and dilute sulfuric acid composition after being dissolved in water, fluid not only flow sensor has punching
Brush effect, more fatal is, and their corrosivity is amplified by geometrical progression under souring, thus causes wedge flow meter
Body perforation damages.The measurement of flow generally uses wedge flow meter, and anti-corrosion type wedge flow meter has application in many fields,
Produce as in chemical industry, store and there is the workshop section of corrosive gas and liquid be required for using, owing to its applying working condition is different, technique
Medium is different, and degree of danger is different, and corrosivity is different, and its technology requires also different.Smelt at chemical industry, etc. there is the industry of corrosion
All there is the problems such as service behaviour is unstable, service life is short.
Publication No.: CN203432624U, the day for announcing is: the Chinese utility model patent of 2014-02-12, discloses one
Plant wedge flow meter, the flange tapping device connected including wedge shape signal generator, described method with described wedge shape signal generator
Blue pressure obtaning device includes the first flange that threeway is connected and be connected with the supervisor of described threeway second with the arm of described threeway
Flange, described threeway is the threeway made by extrusion process.
This wedge flow meter only by high temperature cooling down the pressure casting method of molding, makes surface smoothness good, it is possible to realize
Antiseptical effect, but wedge flow meter can not be made to have wear-resisting advantage.Meanwhile, each components and parts are due to material and technique
Difference, easily produces interference to differential pressure pipeline signal, reduces the accuracy of measurement result.
Utility model content
The purpose of this utility model is, proposes the wear-resisting type wedge flow meter of a kind of simple in construction, it is possible to the suitableeest
For the fluid measurement of the operating mode of the most wear-resisting, severe corrosive, reduce the interference of differential pressure signal pipeline simultaneously as far as possible.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of wear-resisting type wedge flow meter, including adpting flange, pipeline, pressure flange and wedge, described adpting flange,
Pipeline, pressure flange and wedge are formed in one, and adpting flange, pipeline, pressure flange contact with medium with wedge
Surface configuration has wear-resistant coating.
Being additionally provided with corrosion-inhibiting coating in described wedge, described corrosion-inhibiting coating is arranged between wedge and wear-resistant coating.

Being provided with support in described wedge, support is provided with differential pressure transmitter, differential pressure transmitter is with pressure flange even
Connect.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
This utility model can preferably be applicable to the fluid measurement of the operating mode of the most wear-resisting, severe corrosive.Adpting flange, pipe
Road, pressure flange and wedge are formed in one, more closed seamless between each element, then arrange wear-resistant coating and anticorrosion is coated with
Layer, keeps apart medium and wedge flow meter, does not results in corrosion and the abrasion of wedge flow meter, add the property of effusion meter
Stabilizability and service life.Meanwhile, each components and parts use one-body molded, form integral flux meter structure, reduce difference as far as possible
The interference of pressure signal pipeline, improves the accuracy of measurement result.
