Description
Technical field
The utility model technology of instrument and meter field, relates to ultrasonic heat meter, particularly relates to a kind of ultrasonic heat meter pipeline section.
Background technology
At present, the small-bore ultrasonic hotlist pipeline section of existing DN20-DN50, general two kinds of structures, the first structure adopts the mode of reflector plate of settling in measuring channel, the ultrasonic signal that transmitting terminal transducer is launched via two reflectors reflects to receiving end transducer.This architecture signals intensity is by the smooth degree on reflector plate, and emission element can make the flow state of fluid distort, thus brings very large impact to the precision measured, and do not carry out any correction measure, the trueness error brought thus cannot be determined.The second structure is inserted from gateway pipe together with its fixed block by sensor, sensor axle center and pipeline section axis are on the same line, so just make when pipe diameter is less, crushing is just larger, and when flow velocity is larger, flow field state also can be unstable, thus the serious precision that have impact on measurement.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of measuring accuracy high, can solve caliber less time crushing large problem ultrasonic heat meter pipeline section, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of ultrasonic heat meter pipeline section, comprise pipe section, two undergauges laying respectively at pipe end two ends, two trunnion sections laid respectively at outside undergauge, two transducer mounting holes, a temperature sensor fixing hole, temperature sensor is provided with in temperature sensor fixing hole, a transducer is set in each transducer mounting hole, it is characterized in that: described transducer mounting hole site is in undergauge and described trunnion section joint portion, comprise superposed entrance and just to the pit below entrance, be provided with in described transducer mounting hole and insert from entrance, lower end is positioned at the fixed leg in described pit, described transducer is fixed on described fixed leg and is positioned at runner position, two transducers are relative.
In the utility model embodiment, described temperature sensor fixing hole and conduit axis angle at 45 °, and be arranged on the downstream of pipe section.The disturbance causing fluid is avoided to impact temperature sensor.
Described fixed leg is cylinder, and the top of described fixed leg has the convex plane of circumferential section.Such structure ensure that transducer just to direction.
The inwall of described undergauge adopts Vickers equation curve.Such structure can carry out rectification effectively by convection cell, improves measuring accuracy.
Adopt technique scheme, when the utility model is measured, due to two mutual correlation of sensor, avoid the signal attenuation brought by Themiddle refractive process and the problem producing deviation; Sensor inserts from top, reduces crushing; Reducing adopts Vickers equation curve, can carry out effective rectification by convection cell, reduce the measuring error brought thus.
Therefore, the utility model has the advantage that convection cell crushing is little, measuring accuracy is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is structure cut-open view of the present utility model;
In figure:
1-temperature sensor fixing hole, 2-transducer mounting hole, 21-entrance, 22-pit, 3-fixed leg, 31-convex plane, 4-transducer through wires hole, 5-transducer, 7-undergauge, 8-trunnion section, 9-pipe section.
Embodiment
As shown in Figure 1-2, the utility model ultrasonic heat meter pipeline section, comprises undergauge 7, two that pipe section 9, two lays respectively at pipe end 9 two ends and lays respectively at trunnion section 8, two transducer mounting holes 2, temperature sensor fixing hole 1 outside undergauge 7.Be provided with temperature sensor (not shown) in temperature sensor fixing hole 1, in each transducer mounting hole 2, a transducer 5 be installed.
Wherein, transducer mounting hole 2 is positioned at undergauge and described trunnion section joint portion, comprises superposed entrance 21 and just to the pit 22 be positioned at bottom runner below entrance.
Be provided with in transducer mounting hole 2 insert from entrance 21, lower end is positioned at fixed leg 3 pit 22.This fixed leg 3 is cylinder, and its inside has transducer through wires hole 4, and its top has the convex plane 31 of circumferential section.When such structure ensure that the installation of transducer towards, effectively ensure that the surface of emission of two transducers is vertical with conduit axis, and make it fix.
Transducer 5 is fixed on fixed leg 3 and is positioned at runner position, and two transducers 5 are relative.
In addition, in the utility model embodiment, temperature sensor fixing hole 1 and conduit axis angle at 45 °, and be arranged on the downstream of pipe section 9.Can avoid like this causing the disturbance of fluid to impact temperature sensor.
The inwall of undergauge 7 adopts Vickers equation curve.Such structure can carry out rectification effectively by convection cell, improves measuring accuracy.
Be exactly more than ultrasonic heat meter pipeline section of the present utility model, it is when measuring, and due to two mutual correlation of sensor, avoids the signal attenuation brought by Themiddle refractive process and the problem producing deviation; Sensor inserts from top, reduces crushing; Reducing adopts Vickers equation curve, can carry out effective rectification by convection cell, reduce the measuring error brought thus.
Therefore, the utility model has the advantage that convection cell crushing is little, measuring accuracy is high.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; have in any art and usually know the knowledgeable; if in the protection domain not departing from the claim that the utility model proposes; the Equivalent embodiments that local done by the technology contents utilizing the utility model to disclose is changed or modified, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
