The utility model discloses simple structure, production are convenient, have simple to operate, decrease the advantage little, that measurement accuracy is high to fluid pressure, both can be used in the water gauge on, also can be used in on the hotlist.
Description
Technical field
This utility model belongs to technology of instrument and meter field, particularly relates to a kind of low pressure loss long sound path osculum
Footpath ultrasonic measurement pipeline section.
Background technology
At present, the general two kinds of structures of existing small-bore Ultrasonic water meter, the first structure is to measure pipe
In road, positioned beneath has the reflection pillar of 45 ° of reflectings surface, the ultrasonic signal warp that transmitting terminal transducer is launched
Receiving terminal transducer is reflexed to by two reflector plates.The propagation path of this architecture signals is only to survey
To the flow velocity of middle of the stream, certainty of measurement is not the highest, and reflection pillar and undergauge bring no small simultaneously
Crushing.The second structure is to be inserted from gateway pipe together with its fixed block by transducer, transducer axes
The heart with pipeline section axis on the same line, thus makes in the case of pipe diameter is less, crushing
The biggest, and in the case of flow velocity is relatively big, flow field state also can be unstable, thus serious
Have impact on the precision of measurement.The crushing parameter of both the above structure is general all at 25kPa.
Utility model content
Based on this, for above-mentioned technical problem, it is provided that a kind of low pressure loss small-bore ultrasonic measurement of long sound path
Pipeline section.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of long sound path of low pressure loss small-bore ultrasonic measurement pipeline section, including spool piece body, described pipeline section is originally
Internal have entrance, measurement tube chamber and outlet section, the radial direction of described spool piece body being sequentially communicated
Both sides have and are perpendicular to this spool piece body and two ends with described measurement tube chamber connect respectively two transducings
Device installing hole, the tube wall side that described spool piece body is relative with said two transducer installing hole is fixed respectively
One reflector plate, the reflecting surface of two reflector plates is relative with said two transducer installing hole respectively, is formed
The reflection path of N shape, the two ends of described measurement tube chamber are wedge shape.
Described reflector plate includes intubating and reflector plate body, and intubating of said two reflector plate is inserted respectively
Being located in described entrance and outlet section, the bottom of described reflector plate body is and described spool piece body
The adaptive curved portions of tube wall, the upper surface of this reflector plate body is reflecting surface, described reflector plate body
Fix with the described end face intubated.
There is in described spool piece body the ring-type stopper section intubated described in axial stop.
This utility model simple in construction, convenient for production, have easy for installation, convection cell crushing is little, survey
The advantage that accuracy of measurement is high, both can be used on water meter, it is also possible to be used on hotlist.
Accompanying drawing explanation
It is described in detail with detailed description of the invention this utility model below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of long sound path of low pressure loss small-bore ultrasonic measurement pipeline section, including spool piece body
1100。
There is in spool piece body 1100 entrance A, the measurement tube chamber B and outlet section C being sequentially communicated.
The radially opposite sides of spool piece body 1100 have be perpendicular to this spool piece body 1100 and respectively with measurement
Two transducer installing holes 1110 of the two ends connection of tube chamber B, can be respectively perpendicular one ultrasound wave of installation
Transducer.
It is anti-that the tube wall side that spool piece body 1100 is relative with two transducer installing holes 1110 fixes one respectively
Penetrating sheet 1120, the reflecting surface of two reflector plates 1120 is relative with two transducer installing holes 1110 respectively,
Form the reflection path of N shape, owing to reflector plate 1120 is positioned at the pipe that transducer installing hole 1110 is relative
Wall side, the impact of current is fallen below minimum by it, and the crushing within spool piece body 1100 is minimum simultaneously,
Further, the reflection path of N shape can effectively elongate measurement sound path, improves certainty of measurement and the amount of water meter
Journey ratio, it is possible to achieve real drip metering.
Specifically, reflector plate 1120 includes intubating 1121 and reflector plate body 1122, two reflections
Intubating of sheet 1,120 1121 is inserted in entrance A and outlet section C respectively, reflector plate body 1122
Bottom be the adaptive curved portions of tube wall with spool piece body 1100, the upper surface of this reflector plate body is
Reflecting surface, reflector plate body 1122 and the end face intubating 1221 are fixed.
During installation, only need to will intubate in 1121 insertion spool piece body 1100, can be by reflector plate body
1122 lower sections being fixed to transducer installing hole 1110, in this manner it is ensured that the one-shot forming of pipeline section
Fix with the position of two reflector plates, allow production technology become the simplest.
It is also preferred that the left there is axial stop intubate the ring-type stopper section 1130 of 1121 in spool piece body 1100,
It is easily installed.
Wherein, the two ends B1 measuring tube chamber B is wedge shape, can realize wedge shape rectification, the most effectively
The pressure loss reducing pipeline section and impact on current.
This utility model simple in construction, convenient for production, have easy for installation, convection cell crushing is little, survey
The advantage that accuracy of measurement is high, both can be used on water meter, it is also possible to be used on hotlist.
But, those of ordinary skill in the art is it should be appreciated that above embodiment is only
It is used for this utility model is described, and is not used as to restriction of the present utility model, as long as in this practicality
In novel spirit, change, the modification of embodiment described above all will be fallen in this practicality
In novel Claims scope.
