The table body pipeline section modular construction that a kind of ultrasonic signal zigzag is propagated
Technical field
The utility model belongs to ultrasonic signal detection technique field, relates to a kind of pick-up unit, specifically relates to the pipeline section assembly that a kind of ultrasonic flow-velocity is measured.
Background technology
At present, the table body pipeline section assembly of ultrasonic flow meter commonly used roughly is divided into two kinds both at home and abroad.A kind of is ultrasonic signal rectilinear propagation, namely finished by two sensors that send signal and receive signal, and the installation that has a certain degree of sensor and pipeline section axis shape, the centre does not have catoptron; But processing and manufacturing has certain difficulty, and sound wave path is shorter, and the flow field environment is undesirable.Another kind is exactly the ultrasonic signal transmission that takes the shape of the letter U, in the transmittance process of ultrasonic signal except pair of sensors, also finish the transmission of acoustic signals between this is to sensor through the catoptron on a pair of miter angle inclined-plane, the path that acoustic signals is walked is: A-B-C-D.Wherein, the B-C section is effective sound path, is written into the flow rate information of pipeline internal medium in the advancing of acoustic signals; The B-C section is in pipeline center, therefore, is the flow velocity that represents whole pipeline internal medium with the center flow velocity.And measured medium in the pipeline (for example: water) to distribute be approximate parabolical curve form for its flow field velocity, and the center is the fastest, and tube wall place flow velocity is zero, and the shape of this curve is widely different because of the difference of Reynolds number.And catoptron seriously stops current, causes crushing larger, also makes the flow field variation; Therefore, the pipeline section modular construction of U-shaped transmission is scientific and reasonable not.
The utility model content
For the problem that prior art exists, the table body pipeline section modular construction that the utility model provides a kind of ultrasonic signal zigzag to propagate.This pipeline section assembly increases in the constant situation of the distance between the two sensors and is written into measured medium information, has greatly improved accuracy of detection.
To achieve these goals, the utility model adopts following technical scheme, the table body pipeline section modular construction that a kind of ultrasonic signal zigzag is propagated, comprise the table body pipeline section with catoptron mounting hole and installation of sensors hole, be characterized in that a side of opening face in described table body pipeline section is respectively arranged with the first catoptron and first sensor, the opposite side of opening face in described table body pipeline section is respectively arranged with the second sensor and the second catoptron; Described the first catoptron and the second sensor are oppositely arranged, and described the second catoptron and first sensor are oppositely arranged; The two catoptron lines of centres intersect with table body pipeline section axial line.
Described the first catoptron, the second catoptron are fixed on the catoptron mounting hole of table body pipeline section by the catoptron gland.
Described first sensor, the second sensor are fixed on the installation of sensors hole of table body pipeline section by the sensor gland.
In order to realize better sealing, between described the first catoptron and table body pipeline section, the second catoptron with show to be respectively arranged with the catoptron sealing gasket between the body pipeline section.
In order to realize better sealing, between described first sensor and table body pipeline section, the second sensor with show to be respectively arranged with sensor O RunddichtringO between the body pipeline section.
In order to realize better sealing, between described first sensor and the sensor gland, be respectively arranged with the sensor sealing gasket between the second sensor and the sensor gland.
The beneficial effects of the utility model:
Ultrasonic signal is from pipeline one side pipe wall flow velocity is less in the pipeline section assembly of the present utility model, through the maximum pipeline offside tube wall that arrives of center flow velocity, the signal that adopts Z-shaped signal transfer mode to reach liquid flowing state on the full diametric(al) is written into, realize that the complete flow rate information of all position media detects, scientific and reasonable for structure, be greatly improved qualitatively in detection.Therefore, all be to obtain actual measurement no matter how current curve changes, the pipeline section modular construction that no longer transmits as U-shaped, a measured center section velocity of medium, and catoptron seriously blocks water, crushing causes greatly the flow field seriously to make a variation.
