Description
Technical field
The utility model belongs to field of flow meters, more particularly to a kind of integrated intelligent wedge flow meter.
Background technology
Intelligent wedge flow meter is a kind of common flow measurement instrument, and it can be in high viscosity, the stream of low reynolds number
High-precision flow measurement is carried out in the case of body, has incomparable in the flow measurement occasion that flow velocity is relatively low, flow is small, caliber is big
Advantage and irreplaceable effect.Wedge flow meter is mainly used in high viscosity heavy oil, residual oil, diesel oil, machine oil etc., industrial coal
Gas, coke-stove gas, blast furnace gas, producer gas, town gas, hydrogen, nitrogen, air, water vapour, sewage liquid and other medium
Flow measurement.In existing wedge flow meter, pacify for measuring the differential pressure transmitter of differential pressure and being fixed typically by support
On main channel, when installation site and the special angle changing rate of differential pressure transmitter, the sight of staff is difficult to touch difference
Registration on pressure transmitter, difficulty is caused to reading.
The content of the invention
The utility model provides a kind of integrated intelligent wedge flow meter, with asking for solving to propose in above-mentioned background technology
Topic.
The technical problem that the utility model is solved is realized using following technical scheme：The utility model provides one kind one
The intelligent wedge flow meter of bodyization, including main channel, voussoir, pressure pipe and differential pressure transmitter, main channel is provided at both ends with use
It is installed in series the flange on pipeline in by flowmeter, voussoir is arranged on the centre of main channel, and pressure pipe has two, set respectively
Put in the both sides of voussoir, the upper end of pressure pipe is provided with the flange for connecting differential pressure transmitter, described differential pressure transmitter leads to
Two compression fittings crossed on the outside that support is arranged on main channel, differential pressure transmitter pass through high-pressure hose and flange and two respectively
Individual pressure pipe connection, the upper end of described support is provided with dial, and the side of dial is provided with graduation mark, described differential pressure
The bottom of transmitter is fixed with disk, and disk can rotate around the axis of dial, inner surface, the pressure pipe of described main channel
Inner surface, the end face of the surface of voussoir and each flange be provided with anticorrosion antiwear layer.
Described anticorrosion antiwear layer is surfacing coating, and the material of surfacing coating is nickel-base alloy grinding, the thickness of surfacing coating
Degree is not less than 1mm.
The beneficial effects of the utility model are：
1st, gauge outfit of the present utility model is designed using rotary type, after flowmeter installation, and rotating differential pressure transmitter can
Its direction is adjusted, so as to provide facility for reading.The design of high-pressure hose, possibility is provided for the rotation of differential pressure transmitter.
2nd, many existing wedge flow meters have all done anticorrosion antiwear design, and common scheme generally has two kinds, Yi Zhongshi
All parts in addition to differential pressure transmitter are manufactured using high-hardness stainless steel, the stainless steel material of this scheme consumption compares
It is many, therefore manufacturing cost is higher；Another is to add anticorrosion antiwear on the inwall of wedge flow meter by the way of plating
Coating, if coating is excessively thin, it is difficult to ensure that good wearability, if coating is blocked up, processing is time-consuming can very long, electroplating cost
It is too high.And spray welding process is employed in the utility model is needing the Surface Machining of anticorrosion antiwear processing surfacing coating, with electricity
Plating coating is compared, and the coating material price of surfacing coating is less expensive, and process velocity is higher, and anti-wear performance is also more preferable.In addition, using
Surfacing coating is easily guaranteed that larger thickness, thicker surfacing coating can by the surface of anticorrosion antiwear processing in need be linked as one
Body, so as to eliminate the performance short slab in anticorrosion antiwear layer, it is ensured that seemingly anti-wear performance is integrally unified.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- surfacing coatings, 2- main channels, 3- voussoirs, 4- pressure pipes, 5- high-pressure hoses, 6- differential pressure transmitters, 7- circles
Disk, 8- dials, 9- supports.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：
The present embodiment includes main channel 2, voussoir 3, pressure pipe 4 and differential pressure transmitter 6, and main channel 2 is provided at both ends with use
It is installed in series the flange on pipeline in by this flowmeter, voussoir 3 is arranged on the centre of main channel 2, and pressure pipe 4 has two,
The both sides of voussoir 3 are separately positioned on, the upper end of pressure pipe 4 is provided with the flange for connecting differential pressure transmitter 6, described differential pressure
Transmitter 6 is arranged on the outside of main channel 2 by support 9.
Two compression fittings on differential pressure transmitter 6 are connected by high-pressure hose 5 and flange with two pressure pipes 4 respectively,
The design of high-pressure hose 5, the rotation for differential pressure transmitter 6 provides possibility.
The upper end of described support 9 is provided with dial 8, and the side of dial 8 is provided with graduation mark, and described differential pressure becomes
The bottom of device 6 is sent to be fixed with disk 7, disk 7 can rotate around the axis of dial 8.After flowmeter installation, differential pressure is rotated
Transmitter 6 can adjust its direction, so as to provide facility for reading.
The inner surface of described main channel 2, the inner surface of pressure pipe 4, the end face of the surface of voussoir 3 and each flange are all provided with
It is equipped with anticorrosion antiwear layer.
Described anticorrosion antiwear layer is surfacing coating 1.Many existing wedge flow meters have all done anticorrosion antiwear design, often
The scheme seen generally has two kinds, and a kind of is that all parts in addition to differential pressure transmitter 6 are manufactured using high-hardness stainless steel, this
The stainless steel material of the scheme of kind consumption is relatively more, therefore manufacturing cost is higher；Another is in wedge shape by the way of plating
Anticorrosion antiwear coating is added on the inwall of flowmeter, if coating is excessively thin, it is difficult to ensure that good wearability, if coating is blocked up,
