Background technology
In station boiler performance test, mixed flue gas that boiler combustion produces and to enter the amount of fresh air of stove be performance examination
Important step in test amount, is also the important evidence in cool power field test measured air velocity duct.Boiler combustion process
Middle air preheater exiting flue gas amount is the important evidence judging Combustion Operation of Boilers, and the various cold and hot air quantity entered in stove is
Control the important regulating measure of boiler combustion.Particularly low to large-scale flue, the big flow velocity of area, measurement data is difficult to read
Take；Small pipeline elbow is many, velocity variations is difficult to greatly survey in the case of standard.This measurement combination unit can be effectively by measurement data
Stable, amplify and read, it is to avoid large-scale pipeline area is big, flow velocity is low, measure and read difficult and small pipeline elbow is many, velocity variations is big
Artificial measurement error, it is ensured that the accuracy of measurement and reliability.
At present flue gas in power station boiler and the single backing tube of the many employings of gas flow measurement, two back-to-back one end of iron pipe are opened
Mouth other end impulse is measured, and measuring principle is that one end is inserted in pipeline, and the other end connects tosimeter and reads data, will survey during measurement
Buret is progressively extracted by certain length branch, and one group of data of each measuring point reach whole cross section grid survey.The method is measured
The heavy section used time is big compared with long and workload, during low flow velocity is measured error compared with big, accuracy is low, and when small pipeline is measured
The layering of elbow cross sectional flow rate many, same is difficult to survey standard, thus have impact on certainty of measurement.
Summary of the invention
The purpose of this utility model is, the problem existed according to existing station boiler gas flow measurement, this utility model
A kind of station boiler pressure samples amplification, stably measured combination unit are proposed.
The technical solution of the utility model is, this utility model one station boiler pressure samples is amplified, stably measured group
Locking device, including pressure guiding pipe, ladder base and measurement body.
Described measurement body is the double steel pipe of the equal heavy caliber welded together side by side of equal diameter length, surveys for total head for one
Buret, another root is static pressure tube.
Described total head is measured pipe and is measured pipe for windward side full voltage type, measures body and is evenly distributed with multiple on along its length
Equally spaced measurement pore, perforate direction is being just 30 ° to airflow direction phase and angle；The other end measuring pipe is pressure guiding pipe, draws
Pressure pipe level is drawn and is easy to connect silica gel tube.
The measurement body of described static pressure tube is evenly distributed with multiple equally spaced measurement pipe pore on along its length,
Perforate direction is lee face and its angle identical with steam flow direction is 0 °, and end is mounted with to be bent upwards the pressure guiding pipe joint of 30 °.
The medial extremity of described pair of steel pipe is closing, outboard end is that pressure guiding pipe is easy to connect silica gel tube.
Total head is measured and is managed and position identical simply perforate direction equal with the measured hole number of static pressure tube and air-flow folder
Angle.Pressure guiding pipe with measure between pipe with ladder base be connected, the supporting connection of ladder base and in-site measurement hole, thus realize
Seal at measuring point, prevent leakage from causing gasmetry distortion, greatly improve measurement efficiency, simple to operation.
The beneficial effects of the utility model are, this utility model can realize that heavy in section pipe flow speed is low, measurement data is inclined
When little, reading is more difficult, measurement data is amplified and be easy to survey crew reading；Simultaneously when small pipeline elbow is many, flow velocity is layered not
By in the data of fluctuation and realize verity and the accuracy of measurement data under stable case.Additionally this measurement apparatus can realize same
Time grid survey avoid old-fashioned measurement equipment method of point-to-point measurement in different time and improve measurement efficiency and accurately
Property, simple to operation.
This utility model is applicable to flowing flue gas and the speed of air and pressure measxurement.
Accompanying drawing explanation
Fig. 1 is the amplification of this utility model station boiler pressure samples, stably measured combination unit；
Fig. 2 is that the right side of Fig. 1 regards enlarged drawing；
In figure, 1 is pressure guiding pipe；2 is ladder base；3 is static pressure tube；4 is that total head measures pipe；5 is static pressure tube
Measurement pore；6 is the measurement pore that total head measures pipe；7 is plug.
Detailed description of the invention
Detailed description of the invention of the present utility model is as depicted in figs. 1 and 2.
The present embodiment is achieved like this, and the present embodiment one station boiler pressure samples is amplified, stably measured combination
Device, measures pipe 4 and plug 7 including pressure guiding pipe 1, ladder base 2, static pressure tube 3, total head.Static pressure tube 3 and total head are surveyed
Buret 4 is two equal diameters and the double steel pipe of heavy caliber of the equal welding that is connected side by side of length；Static pressure tube and total head measure pipe
Being separately mounted on ladder base 2, wherein plug 7 is arranged on the medial extremity of double steel pipe.
Total head measure pipe 4 be windward side full voltage type measure pipe, measurement body be distributed along its length multiple equidistantly
