Description
Technical field
This utility model relates to the measurement apparatus of fluid flow in pipeline, is specifically related to a kind of multiinjector balance flow meter.
Background technology
Now, in the engineering of all trades and professions, the flow measurement all focusing on the fluid in accurate measurement, particularly fluid engineering laying pipeline all uses effusion meter.Differential pressure flowmeter occupies effusion meter use prostatitis with its technology maturation, simple in construction, feature reliable and stable, use face width.Differential pressure flowmeter is according to the instrument being installed on differential pressure, known fluid condition and detection piece that flow detection part in pipeline the produces physical dimension with pipeline and measuring flow；But, the measurement range ability of this differential pressure flowmeter is narrower, because flow instrument signal (differential pressure), in chi square function relation, thus limits the range ability of flow measurement.At present, the form of nozzle that nozzle flowmeter is the most frequently used has calibrating nozzle, Long Nozzle, Venturi nozzle etc., these throttling forms generally have a disadvantage in that the repeatability of measurement, degree of accuracy mean level in effusion meter, and owing to many factor impacts are intricate, precision is difficult to improve；In-site installation condition requires higher, needs longer straight length, it is difficult to meeting, the pressure loss is bigger.
Summary of the invention
The purpose of this utility model is: provide a kind of multiinjector balance flow meter, its straight length to requiring is short, the pressure reduction of fluid measurement is big, the scope measured is wide, precision is higher, easy to use, and service life is long, the flow of liquid, steam, gas can be measured, be widely used in the departments such as oil, chemical industry, metallurgy, electric power, light industry.
Technical solution of the present utility model is: this multiinjector balance flow meter includes multiinjector equilibrium circular shape plate, ring casing, flanged (FLGD) connecting tube, straight length, pressure pipe and sensor, multiple nozzles of regular uniform arrangement it are dispersed with on multiinjector equilibrium circular shape plate, locating slot and pressure port is set on ring casing, the located groove of multiinjector equilibrium circular shape plate is installed between two ring casings, two flanged (FLGD) connecting tubes lay respectively at outside two ring casings and are linked into an integrated entity by stud, through adpting flange, straight length is installed in flanged (FLGD) connecting tube, pressure pipe is welded on the pressure port of ring casing, soldered sensor on pressure pipe, it is monolithically fabricated multiinjector balance flow meter.
Wherein, the located groove of multiinjector equilibrium circular shape plate, pad are installed between two ring casings.
Wherein, two flanged (FLGD) connecting tube end count packings lay respectively at outside two ring casings and are linked into an integrated entity by stud.
Wherein, multiple nozzles of regular uniform arrangement on described multiinjector equilibrium circular shape plate, multiple nozzles have the common plane of a vertical axis, and circular arc camber constitutes nozzle entrance contraction flow region; throat is drum, and there is the protector preventing damage of edges its exit position.
This utility model has the advantage that
1, there is location and installation groove on ring casing, make installation change easily, easy to maintenance.
2, the flanged (FLGD) connecting tube in two ends is strong with different types of effusion meter interchangeability, facilitates user to install.
3, multiinjector equilibrium circular shape plate surface is through processing, and glacing flatness face is higher, and surface more light, service life is longer, and precision is higher.
4, multiinjector equilibrium circular shape plate is arranged between the ring casing of locating slot, easy for installation, good concentricity, and it is convenient to change.
5, multiinjector balance flow meter has symmetrical multiinjector construction features, can be balanced by stream field, reduces eddy current, vibration and signal noise, flowing field stability is greatly improved, and makes the linearity improve several times than other differential pressure device, and repeatability improves more than 50%, the linearity is high, reproducible.
6, multiinjector balance flow meter due to flow field stable, and other the fast twice of differential pressure device of pressure recovery ratio, substantially reduce the requirement to straight length, thus reduce the installation requirement at scene, also saving a large amount of straight length, especially the pipeline of special expensive material, has saved cost for user.
7, multiinjector balance flow meter decreases the formation of turbulent shear power and eddy current, reduce dynamic loss of energy, under same Test Cycle, the permanent compression loss about twice is decreased compared with other differential pressure device, thus save sizable operation cost of energy, serve energy-conservation effect.
8, find according to service condition: the performance of multiinjector balance flow meter so that it is flow velocity can be from minimum to velocity of sound, and its minimum Reynolds number can be lower, and maximum Reynolds number is bigger, and opening diameter is wider than more, flow measurement range width.
9, being obviously reduced due to its turbulent shear power, considerably reduces medium and directly rubs with throttling element, and opening diameter ratio keeps constant for a long time, and whole effusion meter is without movable member, stable for extended periods of time.
10, multiinjector balance flow meter decreases the formation of turbulent shear power and eddy current, thus greatly reduce the formation being detained dead band, and multiinjector equilibrium circular shape plate surface have passed through process, fineness is higher, ensure that dirty medium passes through multiple hole, reducing the chance that fluid bore is blocked, stain resistance is difficult to block up.
