Abstract
The utility model discloses an ultrasonic base tube for a heat meter, which comprises a tube body (1), a direct flow transducer (2) and a reverse flow transducer (3). Reflecting blocks are arranged in the tube body (1). The ultrasonic base tube for the heat meter is characterized in that the reflecting blocks (4) are two metal cylinders, the two metal cylinders are fixed on a wall in the tube body (1), a reflecting inclined surface is arranged at the upper end of each cylinder, reflecting surfaces of the two reflecting blocks are opposite, and ultrasonic waves sent from the direct flow transducer (2) can be received by the reverse flow transducer (3) after being reflected by the two reflecting blocks (4). The ultrasonic base tube for the heat meter has stable signals, is accurate in metering and low in resistance to fluid in the tube, and accordingly cannot be blocked.
Description
Technical field
The utility model relates to the ultrasonic calorimeter parent tube.
Background technology
The ultrasonic calorimeter parent tube is a kind of device that tube fluid is accurately measured.Ultrasonic calorimeter parent tube commonly used comprises body, attached to following current transducer on the body and the adverse current transducer adaptive with the following current transducer, being provided with the ultrasound wave that reflex block sends the following current transducer in the body can be received by the adverse current transducer, present known structure has two kinds, a kind of is that body and ultrasonic wave table copper shell are X-shaped, following current transducer and adverse current transducer lay respectively at the two ends of copper shell, the shortcoming of said structure is following current transducer and adverse current transducer and body formation angle space, this space produces whirlpool when flowing water, air is difficult for draining clean generation bubble, cause the transducer signal distortion, gather less than signal when serious at all, therefore cause metering inaccurate.Another kind is directly fixedly following current transducer and adverse current transducer on pipeline, and with the plastic reflex block support of PC, two reflex blocks are fixed on the reflex block support, realize the transmission of signal at the pipeline internal fixation.The shortcoming of said structure is: when temperature during greater than 70 degrees centigrade, big flow produces pressure to support, cause distortion, cause the reflector plate angular deflection to adopt and collect signal, influence the flow velocity of water simultaneously in the pipeline by plastic stent, the build-up of pressure loss is bigger, and the 3rd because the ultrasound wave pipeline section does not have filter screen, and the fiber contamination thing in the water hangs on the plastic stent easily and results in blockage.
The utility model content
It is little that the purpose of this utility model just provides a kind of pipeline fluid resistance, and ultrasonic signal is stable, measures effective ultrasonic calorimeter parent tube.
The technical solution adopted in the utility model is: a kind of ultrasonic calorimeter parent tube, it comprises body, attached to following current transducer on the body and the adverse current transducer adaptive with the following current transducer, being provided with the ultrasound wave that reflex block sends the following current transducer in the body can be received by the adverse current transducer, it is characterized in that described reflex block is two metal cylinders, two metal cylinders are fixed on the interior tube wall of body, the right cylinder upper end is provided with reflecting slant, the reflecting surface of two reflex blocks is relative, and the ultrasound wave that the following current transducer is sent can be received by the adverse current transducer after two reflex block reflections.
Adopt technique scheme, because reflex block is a right cylinder, volume is little, places in the pipeline, and the congestion affects of convection cell is little, does not produce bubble and also can not form angle between pipeline and following current transducer and the adverse current transducer, influences the reception of signal.Adopt metal fixed cylinder reflector plate, solved high temperature deformation, guaranteed signal stabilization; Do not have support and other complicated parts in the pipeline, in the mobile process of water, the fiber contamination thing in water directly by pipeline, has been avoided obstruction.
In sum, the beneficial effects of the utility model are: signal stabilization, and accurate measurement, little to the fluid resistance in the pipeline, can not produce obstruction.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, body, 2, the following current transducer, 3, the adverse current transducer, 4, reflex block.
Embodiment
A kind of ultrasonic calorimeter parent tube of the utility model, as shown in Figure 1, it comprises body 1, attached to following current transducer 2 on the body 1 and the adverse current transducer 3 adaptive with following current transducer 2, being provided with the ultrasound wave that reflex block sends the following current transducer in the body 1 can be received by the adverse current transducer, reflex block 4 is two metal cylinders, two metal cylinders are fixed on the tube wall in the body 1, present embodiment is that the inwall at body 1 is provided with outwardly directed recessed channel, and reflex block 4 bottoms embed in the recessed channel and reach fixing.The right cylinder upper end is provided with reflecting slant, and reflecting slant and cylinder are miter angle, and the reflecting surface of two reflex blocks is relative, and the ultrasound wave that following current transducer 2 is sent can be received by adverse current transducer 3 after 4 reflections of two reflex blocks.
