Background technology
At present, utilizing ultrasound wave survey current technology to carry out heat metering is a kind of proven technique, is widely used.Comprise that flow tube, ultrasonic transmission/reception injection device, measuring apparatus constitute, wherein flow is surveyed pipe by two kinds of straight pipeline and curved pipes, uses proof, and the structure of pipeline, shape, material all can exert an influence to the measurement result of flow.At present, employed flow tube, by body, flow inlet, water export, stream entrance point transducer mounting pipe, flow export end transducer mounting pipe and temperature sensor mounting pipe constitute, the temperature sensor mounting pipe is located at flow of hot water and exports on the body of an end, the reflector plate of its reflection supersonic wave is installed in the inside of pipeline, the deficiency of the flow tube of this structure is: the one, because the reflector plate of reflection supersonic wave is the inside that is fixedly mounted on flow tube, the reflector plate surface can produce dirt in the long-play, can cause measuring error, reflector plate but is not easy to clean; The 2nd, because the reflector plate of reflection supersonic wave is installed in the inside of flow tube, taken the space in the pipeline, be easy to cause the obstruction of pipeline, not only influence the accuracy of ultrasonic flow meter metering, finally may cause the ultrasonic flow meter cisco unity malfunction; In addition, reflector plate is installed in the inside of flow tube, when current are out-of-date, can have bubble to produce, if be mixed with bubble in the hot water, will have influence on the accuracy of measurement result, and then also have influence on the accuracy of metering.
Summary of the invention
The purpose of this utility model is to provide a kind of and is easy to clean and maintenance and is difficult for stopping up, being beneficial to the type ultrasonic calorimeter flow tube capable of washing that improves measuring accuracy.
For reaching above purpose, the technical scheme that the utility model adopted is: this type type ultrasonic calorimeter flow tube capable of washing, by flow measurement straight tube body, flow inlet, water export, stream entrance point transducer mounting pipe, flow export end transducer mounting pipe and temperature sensor mounting pipe constitute, stream entrance point transducer mounting pipe and flow export end transducer mounting pipe be vertical respectively be located at flow inlet end and water export end flow measurement straight tube body above, the temperature sensor mounting pipe is located at the flow export end side surface of flow measurement straight tube body, with the current direction axis angle of flow measurement straight tube body be the 30-45 degree, it is characterized in that between stream entrance point transducer mounting pipe and flow export end transducer mounting pipe, being provided with top reflector plate mounting pipe, the internal orifice of top reflector plate mounting pipe is along concordant with the inwall of flow measurement straight tube body, vertical respectively stream entrance point reflector plate mounting pipe and the flow export end reflector plate mounting pipe of being provided with on an effluent measurement amount straight tube body relative with flow export end transducer mounting pipe with stream entrance point transducer mounting pipe, be installed in the signal of the transducer emission in the stream entrance point transducer mounting pipe, through triple reflection, pass to the transducer that is installed in the flow export end transducer mounting pipe, realize the collection of flow signal.
The utility model is also implemented by following measure: described top reflector plate mounting pipe, stream entrance point reflector plate mounting pipe and flow export end reflector plate mounting pipe are equipped with internal thread, corresponding reflector plate all adopts the screw thread mounting means to install and fix, and can be convenient to unpick and wash; The length of described flow measurement straight tube body is 130mm, and interior diameter is 15--25mm; The middle part of described flow measurement straight tube body is provided with the reducing of 10mm.
The beneficial effects of the utility model are: compare with the flowmeter straight pipeline of present use, because the reflector plate that is installed on the flow measurement straight tube body is capable of washing, can prevent that the reflector plate surface from producing dirt in long-play,, can improve the accuracy of metering so the reflection circuit can be not influenced; Owing to stop without any parts during the circulation of smooth, the medium of flow measurement straight tube intracoelomic cavity, in the straight tube body basically without any the pressure loss, so the measuring accuracy height can not stop up fully, is not subjected to the influence of any medium, and is applied widely.
