Description

A kind of ultrasonoscope measuring device
Technical field
The present invention relates to meter fluid flow equipment technical field, particularly a kind of ultrasonoscope measuring device.
Background technology
Traditional ultrasonoscope measuring device is the pipeline using high fusibility material (as metal), and the pipeline replacing high fusibility material with low fusibility material (as thermoplastics such as plastics) appears in the later stage.Although complete low fusibility material pipe cost but connecting head when the fastening ratio of low fusibility material lower than the pipeline of high fusibility material is easier to be destroyed, and easily there is sliding tooth situation after repeatedly assembling.
Existing low fusibility material pipe is all that ultrasonic transducer is affixed on the outside surface of pipeline, and such measuring accuracy can reduce its verticality restive when being affixed on the outside surface of pipeline because of transducer, occurs deviation when causing transducer correlation.And transducer stick after can not remove perfectly, if transducer correlation goes wrong just can not return processing, need together to scrap together with pipeline and transducer.
Existing pipeline is all need to form with Mold Making, tooth classification on connecting head is (made in U.S.A, made in Great Britain), pipeline and dental length all need to determine before Mold Making, as needed change connecting head classification and size can be more difficult after mould completing, many times needing again to open new die and making pipeline.
Existing low fusibility material pipe is multiple accessory composition, generally utilize ultrasonic fusing to process composition, because ultrasonic fusing processing is more unstable, and adjust and confidentially ask more complicated, therefore bad product rate is higher and need expensive equipment, and low fusibility material pipe connecting portion causes easily break in position of plugging into the ability of being stressed is lower.
Existing U-shaped pipe ultrasonic wave transducer is all the top being put in pipeline import and export, and such design air is difficult to flow out from pipeline, causes that measuring accuracy reduces.
