Abstract
The utility model discloses an ultrasonic transducer, its key lies in: which comprises a body, the up end of body is provided with the fixed square platform of installation, the transducing of fixed square platform fixed mounting on class buret is downthehole, the below is provided with the installation head, it installs on the mounting hole in class buret to install first interference, be provided with the recess on the lateral wall of body middle part, be provided with the ultrasonic emission face on the recess. Beneficial effect: (1 )The transducer is all fixed on class buret from top to bottom, prevents that the transducer receives fluid impact, leads to the transducer to take place the displacement, (2 )The transducer is installed with flowing the buret integration, does not need extra support mounting, reduces the influence of the interior fluid flows of convection current buret such as support, (3 )Supersound wave propagation orientation is parallel with the interior fluid flow direction of stream buret, and the computational accuracy is higher.
Description
Technical field
This utility model relates to a kind of physical measuring instrument structure, specifically, is a kind of ultrasonic transducer.
Background technology
Water meter, as flow detector, is widely used；Along with the development of city size, the usage amount of water meter is the most increasing, and for solving problems of management such as monitoring, check meter, the intellectual water meter with the function such as monitoring position, remote meter reading just arises at the historic moment；Existing water meter utilizes ultrasonic transducer to calculate discharge mostly, and existing ultrasonic transducer exists a bigger deficiency, that is, ultrasonic emitting face is positioned at transducer body bottom, and transducer bottom is unsettled in flowtube so that ultrasonic emitting face is the most right.But the flow transducer of this structure, transducer is fixed above in flowtube, but below transducer, bottom is not fixed, long-time by fluid impact in flowtube, transducer easily offsets, and causes ultrasonic emitting face on transducer to offset so that measurement error strengthens；Also having a kind of structure is to be placed with transducer mount in flowtube, and for fixing of energy converter, but this structure is complicated, and multi-part excessively is placed in flowtube, affects the flowing of flow tube fluid.
Utility model content
In view of this, this utility model provides a kind of ultrasonic transducer, is arranged on the sidewall of transducer body in ultrasonic emitting face, by two transducers just to being arranged in flowtube, ultrasonic emitting face is just to ultrasound wave receiving plane, and is positioned on same level line, and computational solution precision is higher；Arranging mounting head by side under the transducer, mounting head is fixedly mounted in flowtube so that transducer upper and lower is all fixedly mounted in flowtube, prevents ultrasonic emitting face on transducer from being offset by fluid impact position.
Concrete technical scheme is as follows:
A kind of ultrasonic transducer, it it is critical only that: includes that body, the upper surface of described body are provided with installation fixing side platform, in the transducing hole that described fixing side's platform is fixedly mounted in flowtube；Lower section is provided with mounting head, and described mounting head interference is arranged on the installing hole in flowtube；It is provided with groove in the middle part of described body on sidewall, described groove is provided with ultrasonic emitting face.
Design based on said structure, transducer upper and lower is all fixedly mounted in flowtube, prevents transducer by fluid impact, causes transducer to be subjected to displacement；Transducer and flowtube integrative installation technology, it is not necessary to extra brackets is installed, reduce the impact that fluid in flowtube is flowed by support etc.；Ultrasound wave direction of transfer is parallel with fluid flow direction in flowtube, and computational accuracy is higher.
Further, described body is divided into three sections, and diameter is sequentially reduced from top to bottom, and described groove is positioned at interlude；Because in flowtube, the discharge managed wall pressure influence at inner wall of flow tube is relatively big, and variant with flowtube center water stream amount, therefore ultrasonic emitting face is placed in flowtube center calculation discharge out more can the actual discharge of true representation.
In the specific implementation, described groove two side and described groove bottom land angle are obtuse angle, are also provided above two bars lead-out wires at described fixing side's platform, for the ultrasonic signal on transducer is passed to peripheral control unit, carry out Correlation method for data processing.
Beneficial effect: (1) transducer is each attached in flowtube up and down, prevents transducer by fluid impact, causes transducer to be subjected to displacement；(2) transducer and flowtube integrative installation technology, it is not necessary to extra mounting bracket, reduces the impact that fluid in flowtube is flowed by support etc.；(3) ultrasound wave direction of transfer is parallel with fluid flow direction in flowtube, and computational accuracy is higher.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model；
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of ultrasonic transducer as shown in Figure 1, it it is critical only that: including that body 1, the upper surface of described body 1 are provided with installation fixing side platform 3, described fixing side's platform 3 is fixedly mounted on the transducing hole of flowtube；Lower section is provided with mounting head 5, and the interference of described mounting head 5 is arranged in the installing hole in flowtube；It is provided with groove 2 in the middle part of described body 1 on sidewall, described groove 2 is provided with ultrasonic emitting face.
Design based on said structure, transducer upper and lower is all fixedly mounted in flowtube, prevents transducer by fluid impact, causes transducer to be subjected to displacement；Transducer and flowtube integrative installation technology, it is not necessary to extra brackets is installed, reduce the impact that fluid in flowtube is flowed by support etc.；Ultrasound wave direction of transfer is parallel with fluid flow direction in flowtube, and computational accuracy is higher.
By Fig. 1 it is also seen that described body 1 is divided into three sections, diameter is sequentially reduced from top to bottom, and described groove 2 is positioned at interlude；Because in flowtube, the discharge managed wall pressure influence at inner wall of flow tube is relatively big, and variant with flowtube center water stream amount, therefore ultrasonic emitting face is placed in flowtube center calculation discharge out more can the actual discharge of true representation.
In the present embodiment, as seen in Figure 2, described groove 2 two side and described groove 2 bottom land angle are obtuse angle, be can be seen that by Fig. 1 to Fig. 2, in order to the ultrasonic signal on transducer is passed to the external world, also it is provided above two bars lead-out wires 4 at described fixing side's platform 3, for the ultrasonic signal on transducer is passed to peripheral control unit, carries out Correlation method for data processing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
