Technical field
It the utility model is related to the ultrasonic transducer fixed network for clamping ultrasonic flowmeter, and in particular to press from both sides to one kind Fill the ultrasonic transducer fastener of ultrasonic flowmeter.
Background technology
Ultrasonic flowmeter is a kind of flow measurement instrument gradually paid attention in recent years.Known ultrasonic flowmeter Usually according to operation time difference principle work.In time difference principle, ultrasonic wave is assessed (especially relative to the flow direction of liquid Ultrasonic pulse, so-called surge) different run times.Therefore, ultrasonic pulse with pipe axis it is at an angle It is transmitted on flow direction and on the direction opposite with flow direction.If it is known that the diameter of line sections, then using run time Difference can determine flow and thus may determine that volume flow.Ultrasound is produced or received by means of so-called ultrasonic transducer Ripple.For this purpose, ultrasonic transducer is fixedly attached to the tube wall of related line sections.Ultrasonic transducer also be used as Clamp measuring ultrasonic wave flow system, such as existing UFT types ultrasonic flowmeter.In such systems, from the outer of measurement pipe Side extrudes ultrasonic transducer against tube wall.Those clamp the characteristics of maximum of measuring ultrasonic wave flow system and are that they do not connect Touch measurement medium and on existing pipeline, thus be widely used in various fields, it is worn by measuring ultrasonic wave Cross and treat that the time of fluid measured realizes the measurement of fluid flow rate and flow, there is non-cpntact measurement, no pressure loss, application Extensively, strong applicability, the advantages that safeguarding is easily installed, is widely applicable for various fluid media (medium)s and working condition, including high temperature, height The measurement of the special media flow such as pressure, non-conductive, severe corrosive, explosive and radioactivity.But clamp supersonic flow existing In system for measuring quantity, ultrasonic transducer is fixed on the tube wall of related line sections usually using the fixation bandage of iron chains, still, The fixing device of many ultrasonic transducers is to repeatedly kick into capable fastening by chain bandage etc., the bad control of dynamics of this mode, Too tight easily damage ultrasonic transducer, it is too loose, then it can influence measurement accuracy.
Utility model content
Technical problem to be solved in the utility model is the bad control of fastener dynamics of ultrasonic transducer.
To achieve these goals, technical scheme provided by the utility model is:It is a kind of to clamp the super of ultrasonic flowmeter Sonic transducer fastener, including bottom plate, the lower end of the bottom plate is provided with transducer, and the lower end of transducer is against the pipe of downside On road, the upper end of the bottom plate is circumferentially with upward guide rod, and guide rod is socketed with pressing plate and support successively from top to bottom Plate, the upper end of the guide rod is connected with block, and the lower end of block is against the upside of supporting plate, and the lower end of the supporting plate is left Right both sides are hingedly connected with flap, and bottom plate and pressing plate are respectively positioned between two flaps, the lower end of the flap be connected with The clamping plate of circular arc corresponding to pipeline, and two relative end faces of clamping plate are squeezed on pipeline, the lower end of the clamping plate is connected with company Block is connect, and two contiguous blocks are located at the downside of pipeline, are connected between two contiguous blocks by screw bolt and nut, under the pressing plate Spring is uniformly provided between end and bottom plate, and the upper center of supporting plate is plugged with threaded rod, the lower end of the threaded rod and pressure It is rotatablely connected between plate, the upper end of the threaded rod is provided with spin-block.
Preferably, it is threadedly coupled between the block and guide rod.
Preferably, be formed in one structure between the flap, clamping plate and contiguous block.
Preferably, connected between the threaded rod and pressing plate by taper roll bearing.
The utility model is designed, and transducer is placed on pipeline first, puts down the clamping plate of both sides, will by screw bolt and nut Two contiguous blocks are fixed, and rotate spin-block, and threaded rod moves down, and pressing plate extrudes bottom plate by spring, and transducer and pipe are driven by bottom plate Road contacts, and so, under the action of the spring, ensures that dynamics is not too large, also will not be too loose, has certain toughness, well Transducer is protected, also improves measurement result.
