Description
Technical field
The utility model belongs to ultrasonic flowmeter watchcase production field, is specifically related to a kind of ultrasonic flowmeter watchcase with square pipeline section.
Background technology
Ultrasonic flowmeter utilizes ultrasound wave time difference principle, realize the device that liquid or gas flow are measured, compared with traditional mechanical type gauging table, ultrasonic flow rate measuring table has the advantages such as low, the high accuracy of measuring of initial-flow is high, crushing is little and is widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.
The watchcase of ultrasonic flowmeter is by holding the cavity of each electronic devices and components and treating that the measurement pipeline section that fluid measured flows through forms for supplying, measure pipeline section through cavities side to arrange, ultrasonic transducer is then arranged on to be measured on pipeline section for launching and receiving ultrasound wave, obtain temporal information, and then obtain rate of flow of fluid.Pass through for the ease of installation and fluid, measure pipeline section and usually adopt hollow cylinder build structure, therefore measuring pipeline section is a curved surface at the outside surface of inside cavity, problem is the outside surface of curved face type and is unfavorable for the installation of ultrasonic transducer, as depicted in figs. 1 and 2, just needing in this case to offer transducer accommodation hole for fixedly mounting ultrasonic transducer on measurement pipeline section, being unfavorable for the further simplification of ultrasonic flowmeter watchcase production technology.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of ultrasonic flowmeter watchcase simplifying structure.
For realizing above object, the technical solution adopted in the utility model is: a kind of ultrasonic flowmeter watchcase, comprise the cavity 10 of integrated injection moulding and measure pipeline section 20, described measurement pipeline section 20 through cavities 10 side is arranged, it is provided with at least one ultrasonic transducer, the part of described measurement pipeline section in cavity has one for installing the flat outer surface of ultrasonic transducer, and described flat outer surface is greater than the diameter of described ultrasonic transducer perpendicular to the width measured on pipeline section direction.
Preferably, described measurement pipeline section is a rectangle at the xsect that inside cavity is divided.
Preferably, described measurement pipeline section is one with the rectangle of chamfering at the xsect that inside cavity is divided.
Preferably, described measurement pipeline section is a rectangle with arc-shaped side at the xsect that inside cavity is divided.
Preferably, the partial cross sectional of described measurement pipeline section outside cavity is annular.
Technique effect of the present utility model is: in the measurement pipeline section of ultrasonic flowmeter and the integrated injection moulding process of cavity, measuring tube section is positioned at face that cavity is used for installing ultrasonic transducer and is set to the flat outer surface that a width is greater than transducer diameter, ultrasonic transducer directly can be fixed in described flat outer surface, do not need to offer placement hole in addition, effectively simplify watchcase production technology.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
As depicted in figs. 1 and 2, a kind of watchcase with the ultrasonic flowmeter of square pipeline section is made up of cavity 10 and measurement pipeline section 20, cavity 10 is for holding each electronic devices and components measured and show rate of flow of fluid, and measure pipeline section 20 for for treating that fluid measured flows through and through cavities 10 is arranged, measurement pipeline section at least installs a ultrasonic transducer for transmitting and receiving ultrasound wave.In order to reduce assembly cost and improve sealing property, the cavity in the meter casing structure of ultrasonic flowmeter and this employing of measuring tube segment base integrated injection moulding form.In the prior art, measure pipeline section and usually select hollow cylindrical structure, therefore measure pipeline section the part of inside cavity be also one cylindrical, and columniform outside surface is a curved surface, then transducer accommodation hole 50 must be offered when we install ultrasonic transducer thereon so that stable installation transducer.
In order to simplify the production technology of ultrasonic flowmeter watchcase, the utility model provides a kind of ultrasonic flowmeter watchcase with square pipeline section of simplification, its key is: the outside surface that the part 21 measuring tube section being positioned at cavity is used for installing ultrasonic transducer is set to flat outer surface 211, and described flat outer surface is greater than the diameter of described transducer at the vertical width with measuring on pipeline section direction, so that be directly installed in flat outer surface by transducer, realize the object simplifying watchcase production technology.
Preferably, measure the portion 22 of pipeline section outside cavity and can use hollow cylinder, so that be connected in pipe network by ultrasonic flowmeter.
Below providing three kinds of specific embodiments, as shown in Fig. 3, Fig. 4, Fig. 5, is ultrasonic flowmeter watchcase cross-sectional schematic:
Embodiment 1, as shown in Figure 3, described measurement pipeline section is a rectangle at the xsect outline of inside cavity, the length and width group of described rectangle needs the demand combining required flow and the strength of materials to determine further, as long as the diameter that the width for the flat outer surface 211 of installing ultrasonic transducer is greater than transducer can realize transducer to be directly mounted to the object of flat outer surface, adhesive strength large acoustic impedance matching layer 30 is preferably adopted transducer to be fixedly attached to the flat outer surface measured on pipeline section.
Further embodiment 2, as shown in Figure 4, rectangular cross section in embodiment 1 can be arranged two symmetrical chamferings in the edge of flat outer surface 211, the demand that transducer is directly installed on flat outer surface can not only be met and can also save certain space, certainly described two symmetrical chamferings are the simplest schemes of the present embodiment, also described chamfering can be set to the combination of multiple chamfering or the combination of rounding and rounding, same technique effect can both be reached.For the technical program, transducer is fixedly attached in the flat outer surface of measurement pipeline section by the same large acoustic impedance matching layer 30 of adhesive strength that preferably adopts.
Embodiment 3, as shown in Figure 5, described measurement pipeline section is the rectangle with arc-shaped side at the outline of the xsect that inside cavity is divided, corresponding to being have arc-shaped side in stereographic map.The side of described arc-shaped can not only meet the technique effect that the utility model brings, more can at utmost to save the space of inside cavity, comprise the space of pipeline section upper and lower, be more preferred technical scheme, transducer is fixedly attached in the flat outer surface of measurement pipeline section by the same large acoustic impedance matching layer 30 of adhesive strength that preferably adopts.
Three kinds of embodiments listed by this instructions can not summarize all technical schemes that can realize the utility model object, and protection domain of the present utility model should be as the criterion with claims.
