Abstract
The invention relates to a structure device applied to self-flowing type fluid ultrasonic measurement. A baffle plate (2) used for alleviating rolling of a fluid is installed in a pipeline main body (1); the material inlet of the pipeline main body (1) is provided with one pair of fluid buffering plates (3); fixing clamp grooves (4) are connected behind the fluid buffering plates (3); and fixing holes (5) for mounting sensors are formed behind the fixing clamp grooves (4). When a fluid to be measured does not fully fill a pipe and contains a large number of air bubbles in a flowing process, on-line measurement of relevant physical parameters cannot be performed, while, with the structure device adopted, the above situation can be avoided.
Description
Technical field
The present invention relates to a kind of fluid bearing arrangements, relate to a kind of structure for fluid physics measurement amount in pipe gravity flow pipeline specifically.
Background technology
Along with the raising gradually of industry spot automatization level, detect the online physical quantity instrument of industrial fluids, to appear in various industry spot also in a large number.The transmitting power of industrial fluids adopts the form of installation pump on pipeline mostly, is commonly called as pressure pipeline.Only have small part pipeline adopt with industrial fluids own wt for power, allow industrial fluids in the duct oneself flowing.This only designs for the condition of pressure pipeline with regard to causing the online physical quantity detection device of major part, seldom can take into account pipe gravity flow pipeline.
Industrial fluids is in the transportation of pipeline, and the fluid in pressure pipeline is full of whole pipeline section, containing the uniform bubble seldom measured.And industrial fluids is in gravity flow process, the pack completeness in pipe design work is 40% ~ 60% of pipeline section cross-sectional area, and pipeline is in practical work process, and its inner pack completeness also can be less than design data.This just causes industrial fluids not to be filled with pipe interior, and in flow process, fluid is that constantly rolling is advanced, and this makes to carry bubble irregular, uneven in a large number in fluid.In view of pipe gravity flow pipeline not full packages, the very large situation of air bubble content, make the industrial fluids of gravity flow be difficult to carry out the measurement of online physical quantity, this just causes, on some pipe gravity flow pipelines, can't realizing higher Automated condtrol.
Summary of the invention
For on above-mentioned pipe gravity flow pipeline, the defect of the online physical quantity of industrial fluids, patent of the present invention provides a kind of structure can carrying out online physical quantity at pipe gravity flow pipeline.
Solving the problems of the technologies described above taked measure is: a kind of structure for fluid physics measurement amount in pipe gravity flow pipeline, the baffle plate (2) for weakening fluid rolling is installed in pipe main body (1), at the feeding mouth of pipe main body (1), fill a pair fluid cushion plate (3), the clip slot (4) with constant spacing is connected at the rear of fluid cushion plate (3), at clip slot (4) rear with constant spacing, providing a pair can for the fixed orifice (5) of sensor installation.
Beneficial effect of the present invention:
1, solve in pipe gravity flow pipeline, industrial fluids not full packages causes the problem that can not carry out measuring;
2, make the industrial fluids in pipe gravity flow pipeline reduce at measured zone air bubble content, improve measuring accuracy.

Embodiment
Be described with reference to the accompanying drawings the structure of patent of the present invention.
A kind of structure for fluid physics measurement amount in pipe gravity flow pipeline, the baffle plate (2) for weakening fluid rolling is installed in pipe main body (1), at the feeding mouth of pipe main body (1), fill a pair fluid cushion plate (3), the clip slot (4) with constant spacing is connected at the rear of fluid cushion plate (3), at clip slot (4) rear with constant spacing, providing a pair can for the fixed orifice (5) of sensor installation.
Pack completeness according to pipe gravity flow pipeline design is 40% ~ 60% of pipeline section cross-sectional area, and baffle plate (2) needs the horizontal diameter position being arranged on pipe main body (1), makes the cross-sectional area of space A be the half of conduit cross-sectional area, namely
angle between two buffer boards (3) will be not more than 90 °, and generally, the angle between two buffer boards is advisable between 80 ° ~ 90 °, the length of constant spacing clip slot (4), need to be greater than 300mm, to guarantee that fluid has enough Bubbles, ascent time, the width of clip slot (4), need to determine according to the actual pack completeness in pipeline, generally, the area of space B between 10% ~ 20% of conduit cross-sectional area, namely
, fixed orifice (5) installed by sensor needs to be arranged on clip slot (4) discharge port end near the position of tube wall.
When the fluid in pipe gravity flow pipeline is in flow process, when arriving the feeding mouth of pipe main body (1), due to the area of space under pipeline baffle plate (2), diminish rapidly after buffer board (3) transition, make space B be full of fluid media (medium) rapidly, remaining fluid media (medium) will continue flowing through space A.Due to the existence of baffle plate (2), fluid media (medium) will tend to be steady during flowing in fixing clip slot (4), bubble contained in fluid media (medium) can be separated out, be floated, and when flows through sensor installs fixed orifice (5), fluid media (medium) just can meet normal measuring condition.
Claims (5)
1. one kind is applied to the constructional device of gravity flow fluid ultrasonic measurement, it is characterized in that: in pipe main body (1), install the baffle plate (2) for weakening fluid rolling, at the feeding mouth of pipe main body (1), fill a pair fluid cushion plate (3), clip slot (4) is connected and fixed at the rear of fluid cushion plate (3), at fixing clip slot rear, providing can for the fixed orifice (5) of sensor installation.
2., according to claim 1, the Space Cross Section that baffle plate (2) and fixing clip slot (4) form amasss, and can determine according to actual pipeline pack situation,
