Abstract
The utility model discloses an ultrasonic water shows rectifier, including the radome fairing of conical duct column structure, the entrance point diameter of this radome fairing is greater than the exit end diameter, have a polylith flow distribution plate along circumference evenly distributed on the radome fairing inner wall, per two adjacent form the rectification passageway between the flow distribution plate, the exit end of radome fairing is equipped with the baffle rather than internal diameter looks adaptation, is equipped with the rectification hole that is cellular distribution on this baffle. The utility model has the advantage of simple and novel structure, be convenient for make, have good rectification effect, and easily installation.
Description
Technical field
The utility model relates to a kind of intellectual water meter parts, especially ultrasonic water meter rectifier.
Background technology
Ultrasonic water meter is a kind of to fluid emission ultrasonic signal, after it is subject to fluid flow effect, then receives this ultrasonic signal, and testing result is used for the measurement instrument of flow measurement.Because it has noncontact, without crushing, the advantage such as precision is high, cost is low, structure is simple, measurement range is wide, is able to widespread use in industrial and agricultural production.
The measurement result of ultrasonic water meter affects comparatively large by rate of flow of fluid, in order to ensure the stability of rate of flow of fluid, usually need on ultrasonic water meter, to install rectifier, to guarantee the accuracy of measurement result.The rectification effect of conventional rectifier is unsatisfactory, and common configuration is complicated, and production cost is higher.
Utility model content
In view of this, the utility model provides a kind of structure simple, has the ultrasonic water meter rectifier of good rectification effect.
Its technical scheme is as follows:
A kind of ultrasonic water meter rectifier, comprise the radome fairing of tapered tubular structure, the entrance point diameter of this radome fairing is greater than endpiece diameter, described radome fairing inwall has been uniformly distributed circumferentially polylith spreader plate, rectification passage is formed between every two pieces of adjacent described spreader plates, the endpiece of described radome fairing is provided with the baffle plate suitable with its internal diameter, and this baffle plate is provided with the rectification hole in cellular distribution.
Adopt above structure, fluid, when flowing through rectifier, under spreader plate effect, is divided into multiply to carry out shunting by one regular, then collects for one through rectification hole, and in the process, the non-steady state of fluid is able to good elimination, and rectification effect is good.
As preferably, on arbitrary radial section of radome fairing, the height of described spreader plate is all less than the section radius of this radome fairing, namely in radome fairing center, leave make fluid normal through space.
Enter for ease of fluid, and reduce crushing as far as possible, described spreader plate is provided with the guidance part of arc in the end near cowling outlet end.
As preferably, the height of described spreader plate reduces along entrance point gradually to endpiece direction, like this, on arbitrary cross section of radome fairing, the arc radius that each spreader plate end face surrounds is substantially equal, and the flow state of the fluid flowing through radome fairing center position can be made more stable.
As preferably, described radome fairing has been uniformly distributed circumferentially fin, this fin rectangular in cross-section on the outer wall of its entrance point and endpiece, and this structure can guarantee that rectifier does not need can stably be installed on water meter by other coupling arrangement.
For convenience of manufacturing, described baffle plate, spreader plate and radome fairing integrated formed structure.
Beneficial effect:
Adopt the ultrasonic water meter rectifier of above structure, its structure is simply novel, is convenient to manufacture, and has good rectification effect, and is easy to install.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is planar structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of ultrasonic water meter rectifier as depicted in figs. 1 and 2, comprise the radome fairing 1 of tapered tubular structure, the entrance point diameter of this radome fairing 1 is greater than endpiece diameter, on the outer rim end face of entrance point and endpiece, circumferentially be distributed with multiple fin, to facilitate the installation of rectifier and water meter, be provided with the baffle plate 3 suitable with its internal diameter at the endpiece of radome fairing 1, this baffle plate 3 is provided with the circular rectification hole 31 in cellular distribution.
Described radome fairing 1 inwall has been uniformly distributed circumferentially polylith spreader plate 2, in the present embodiment, spreader plate is preferably 6 pieces, rectification passage 2a is formed between every two pieces of adjacent spreader plates 2, this spreader plate 2 axially extends along radome fairing 1, and perpendicular to radome fairing 1 inwall, to be partitioned into many rectification passage 2a in radome fairing 1.
Spreader plate 2 by circular arc chamfering transition in its end near radome fairing 1 entrance point, forms the guidance part 21 of arc, to facilitate fluid to enter, and reduces crushing, this guidance part 21 end and radome fairing 1 entrance point end face.
Radome fairing 1 arbitrary radial section on, the height of spreader plate 2 is all less than the section radius of this radome fairing 1, radome fairing 1 inside center is made to leave the space passed through for fluid, the height of this spreader plate 2 reduces along entrance point gradually to endpiece direction, the space making this be positioned at radome fairing 1 inside center is roughly cylindrical, guarantees the smooth flow of fluid.
After being installed to water meter, fluid enters along rectifier entrance point, after spreader plate segmentation is in multiply, rectification hole 31 again on endpiece baffle plate 3 carries out segmentation rectification, afterwards at endpiece exchange set, make the non-steady state of fluid be able to good elimination, substantially increase rectification effect.
Finally it should be noted that; foregoing description is only preferred embodiment of the present utility model; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, such conversion all falls within protection domain of the present utility model.
