  • Venturi Tube - China

    price: contact company for price

    Venturi tube
    Product name: venturi tube
    Product code: 16311-252
    Update time: 2015.08.25
    Views: 913
    Processing custom origin: in kaifeng
    Venturi tube models: the throttle device
    Type: venturi tube
    Measuring range: 50-1000 - mm
    Nominal size: 50-1000 - mm
    Accuracy: + 0.1% to + 1.5%
    Pressure of work: 4.0 (Mpa)
    Scope of application: gas, liquid
    throttling device, also known as differential pressure flowmeter, Orifice flowmeter contains (integrated orifice flow meter, standard orifice, annular orifice flow meter, integrated annular orifice flow meter)
    Venturi tube can be divided according to function name gas flow meter, flue gas meter, steam flow meter, gas flow meter, compressed air flow meter, liquid flow meter. Classic venturi tube is also called the classical venturi tube, used to call standard venturi tube. IS05167 or GB/T2624 standard. Used to measure stable single-phase fluid flow in a closed pipe, often used to measure air, gas, gas, water and other fluid flow. Venturi tube (Venturi throat) according to the structure is divided into working "Venturi tube and plug-in Venturi tube. Hot blast stove combustion wind in a steel plant, the cold wind, gas metering (blast furnace gas, coke oven gas, converter gas) and thermal power plant boiler primary air and secondary air big diameter pipe, low velocity meter measurement has received the good effect. To solve the existing industrial enterprises in the low pressure, large diameter, all kinds of low velocity gas flow precise measurement. Wide measuring range, easy installation of flow measuring devices. Unique structure design and data processing method is strictly on the basis of fluid mechanics, and in the national large-scale key wind tunnel laboratory compaction flow calibration.
    USES: can be widely used in the oil, chemical industry, metallurgy, electric power and big diameter control and measurement of the fluid.
    1, simple structure, durable, stable performance.
    2, small pressure loss, the energy saving fluid conveying.
    3, 50-1200 range in size, don't need real flow calibration. Beyond this range, you can reference. When requiring high precision, real flow calibration can be performed.
    4, installation size of ontology is longer, the large diameter instrument, not easy to transport installation.
    The main technical parameters:
    Nominal diameter (mm) : (to 48 ") (2600)
    Nominal pressure (MPa) : 0.25 4.0 (6.3)
    Precision (uncertainty) : + 0.1% to + 1.5%
    (1) on the fluid resistance small, about 150 pa so low energy consumption.
    (2) the pressure difference is big, high precision, wide measurement range.
    (3) stability is good, have a smooth differential features.
    (4) the use of a wide range, general gas, flue gas, blast furnace gas containing impurities more, use for a long time without blocking phenomenon.
    (5) convenient installation, easy to maintain for a long time.
    (6) before and after the straight pipe, shorter than standard throttle device, 1 D after about 1.5 D.
    (7) with temperature and pressure from online correction integration structure.
    Double venturi tube of speed is a kind of used for power plants of large diameter gas pipeline flow measurement, measurement of large diameter pipeline flow velocity differential pressure sensitive, cooperate with the differential pressure transmitter, record and display instrument tube can be obtained by measuring point of the instantaneous velocity value. By adjusting the instrument can also be adjusted in pipe flow, its characteristics are as follows: compared with the throttling device: small volume. Permanent minimal pressure loss. Simple structure, it is convenient for inspection, cleaning and maintenance of all.
    Parameter is introduced:
    (1) the applicable industrial pipeline: circular cross section pipe nominal diameter:
    DN = 500 ~ 4000 mm rectangle pipe: W * H = 600 * 600 ~ 3600 x 3600 mm and the width and height of the rectangular pipe.
    (2) the nominal pressure: PN acuities were 6.4 MPa
    (3) working temperature lower than 400 ℃ (higher than 400 ℃, the order should be specified)
    (4) the differential values: 0 ~ 1.0, 1.6, 2.5, 4, 6.3, 10, 16, 25 and 40 kpa
    (5) repeatability error: + 0.1% to + 1.5%
    (6) stability: plus or minus 10 pa
    (7) level of accuracy: 0.5 on the Richter scale, level 1, 1.5 on the Richter scale, level 2
    (8) sensor over size: welded steel pipe G3/4 ", M20 x 1.5 or 1/2 NPT
    (9) measured medium, metallurgy, blast furnace gas, the cold wind, combustion-supporting air, gas, mixed gas, flue gas, recycle
    Power: a wind, secondary air, coal and wind, etc
    Chemical industry: corrosive gas, air and other media
