Background technology
At present, existing pipeline ultrasonic flow rate, calorimetric transducer, its Measurement channel pipe segment structure used is formed primarily of pipeline section wall, sensor mounting hole, reflecting body, such as, the Chinese patent " ultrasonic flow rate, Calorimeter Converter Using For Measuring Pipe Run " of the applicant, patent No. ZL 200520016285.4, ZL 200520107503.5 and ZL 200520107502.0; And " there is the ultrasonic flow rate of beam function, Calorimeter Converter Using For Measuring Pipe Run ", patent No. ZL201020275319.2.In use there is the problem of a general character in this several structure, if when pipeline internal medium has freezing icing phenomenon to occur exactly, this several measuring tube segment body all can be subject to damage in various degree, thus causes instrument normally to measure.
Utility model content
The utility model object is to provide a kind of ultrasonic flow rate, the Calorimeter Converter Using For Measuring Pipe Run with antifreeze function, guarantee when pipeline internal medium has freezing icing phenomenon to occur, therefore measuring tube segment body can not be damaged and affect instrument and normally measure, and solves Problems existing in background technology.
The technical solution of the utility model is:
There is the ultrasonic flow rate of antifreeze function, Calorimeter Converter Using For Measuring Pipe Run, comprise pipeline section, sensor mounting hole, reflecting body, snap ring and annular groove, pipeline section wall is provided with sensor mounting hole, and with the endoporus UNICOM of pipeline section, reflecting body is arranged in the endoporus of pipeline section; In pipeline section, bore ends is provided with annular groove, and snap ring is annular, is arranged in annular groove, and snap ring is pressed close to reflecting body and arranged.
Said snap ring is sheet open annular, and the shape of annular groove and size form according to the actual conditions accessory processing of snap ring, and the flexible fastening of snap ring dependence itself is in annular groove, and the two supports the use.The shape of snap ring and pattern can be arbitrary, and the fixed form of snap ring on annular groove or pipeline section is also arbitrary, such as, can be fixed on annular groove or pipeline section by welding, bonding form.
Described sheet open annular snap ring, two ends of its opening part are respectively equipped with mounting hole, are convenient to snap ring to be installed in annular groove, such as: employing instrument penetrates two mounting holes, snap ring is pressed from both sides flat after be installed in annular groove.
When adopting the utility model to carry out detection flow, if medium generation freezing phenomena in field pipes, snap ring can be subjected to displacement by blocking reflected body, avoids and affects instrument measurement because reflecting body moves.
The beneficial effects of the utility model: owing to increasing annular groove and install snap ring after reflecting body, adopt the snap ring not affecting measurement performance from measurement pipeline section side location and installation, not only easy for installation but also do not affect measuring accuracy.The utility model have rational in infrastructure, improve pipeline section body resistance to frost the feature such as measuring accuracy, easy accessibility can be ensured, the utility model improves the resistance to frost of test pipeline section, easy disassembly, can be widely used in ultrasonic flow rate, calorimetric converter.
