Description

Technical Field

[0001] The utility model relates to the technical field of data measurement, in particular to a flow totalizer with high measurement accuracy. Background Art

[0002] A flow totalizer is a secondary instrument used to measure and calculate fluid flow. Flow totalizers are usually used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters, and pressure transmitters. They can measure and display flow parameters, perform cumulative calculations, alarm control, transmission output, data acquisition, and communication. The flow totalizer can be set as needed and can display instantaneous flow, cumulative flow, temperature, pressure, and other parameters. The flow totalizer can also perform cumulative calculations on the mass, volume, and length of a substance, and perform batch control. Common calculation methods include the input pulse number calculation method, which calculates the cumulative flow by calculating the number of pulses received within a measurement cycle.

[0003] The flow totalizers currently in use usually adopt a form in which the instrument and the measuring device are separated from each other. Although this method is convenient for measuring some pipelines, its convenience is affected to a certain extent. In addition, since the measuring device is usually fixed on the outside of the pipeline, this also leads to the wear and tear of the pipeline inside during measurement, which can easily affect the measured data during measurement. Therefore, a flow totalizer with high measurement accuracy is proposed. During measurement, the measurement position can be quickly adjusted according to needs, and conclusions can be drawn by referring to the average data, thereby improving the accuracy of the measurement data. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a flow totalizer with high measurement accuracy, which has the advantages of good flexibility and high data accuracy, and solves the problem that the traditional flow totalizer may cause low data accuracy due to the fixed measuring device during measurement.

[0005] In order to achieve the above-mentioned purpose of good flexibility and high data accuracy, the utility model provides the following technical solutions: a flow integrator with high measurement accuracy, including an instrument body, a measuring component arranged inside the instrument body, a control component arranged inside the instrument body, and an adjusting component arranged on the side of the instrument body; the measuring component includes a measuring cavity opened inside the instrument body, an adjusting box fixedly installed on the side wall of the measuring cavity, a pulse transmitter movably connected to the side of the adjusting box, a fixing frame movably connected to the side wall of the measuring cavity, and measuring holes opened on both side walls of the instrument body.

[0006] Furthermore, an arc groove of matching shape is provided on one side opposite to the fixing frame, a plurality of slot holes are provided on the arc groove wall of the pulse transmitter, a rotating connecting ball is provided inside the slot holes, and an anti-slip pad is fixedly installed on the arc groove wall of the fixing frame.

[0007] Furthermore, a fixedly installed adjusting bolt is disposed on the back of the fixing frame. The adjusting bolt transversely penetrates the side wall of the instrument body and is rotationally connected to the instrument body through a thread.

[0008] Furthermore, an adjusting motor is fixedly installed on the inner wall of the adjusting box, a double-headed threaded rod is fixedly installed on the end of the output shaft of the adjusting motor, a plurality of threaded sleeves are rotatably connected to the outer side of the double-headed threaded rod, and a connecting rod is fixedly installed on the side of the threaded sleeve.

[0009] Furthermore, a sliding groove is provided on the side of the regulating box, a connecting rod passes through the sliding groove horizontally and is slidably connected to the sliding groove, and a side of the connecting rod and a side of the pulse transmitter are fixedly installed.

[0010] Furthermore, the threads at both ends of the double-threaded rod are in opposite directions, and a limit plate is provided on the side of the connecting rod located inside the sliding groove to prevent rotation.

[0011] Furthermore, the control component includes an equipment cavity opened inside the instrument body, a pulse signal instrument fixedly installed on the side of the equipment cavity, and a circuit board fixedly installed on the side wall of the equipment cavity.

[0012] Furthermore, the adjustment component includes a display board fixedly mounted on the side of the instrument body, a data display fixedly mounted on the side of the display board, a control panel fixedly mounted on the side of the display board, and a control button fixedly mounted on the side of the control panel.

[0013] Compared with the prior art, the utility model provides a flow totalizer with high measurement accuracy, which has the following beneficial effects:

[0014] 1. This flow integrator with high measurement accuracy inserts the flow pipe into the integrator from the measuring hole, rotates the adjusting bolt, and pushes the fixing frame close to the pulse transmitter while the adjusting bolt rotates on the side wall of the instrument body, so as to cooperate with the pulse transmitter to clamp the fluid pipe passing through the middle. Press the control button to control the pulse signal instrument to generate pulses. The pulse transmitter emits the pulse signal from the arc slot to measure the flow inside the pipeline. After the measurement is completed, the data display shows the data measured at the current measurement position.

[0015] 2. The flow integrator with high measurement accuracy starts the regulating motor, and the output shaft of the regulating motor drives the double-headed threaded rod to rotate. The side of the threaded sleeve is fixedly installed with a connection inside the sliding groove, so that the threaded sleeve cannot rotate. Therefore, the threaded sleeve moves laterally on the outside of the double-headed threaded rod. The lateral movement of the threaded sleeve drives the movement of the connecting rod. The movement of the connecting rod drives the pulse transmitter to move on the side of the fluid pipeline through the ball, thereby changing the relative position of the pulse transmitter and the fluid pipeline. The pulse transmitter is used to transmit pulses again for measurement. After repeatedly changing the relative position of the pulse transmitter and the pipeline, more accurate measurement data is obtained, which solves the problem of low data accuracy caused by the fixed measuring equipment during measurement in traditional flow integrators.

[0025] The pipeline is clamped by arranging the pulse transmitter 23 and the fixing frame 24 in coordination.

[0026] In this embodiment, a fixedly installed adjusting bolt 26 is disposed on the back of the fixing frame 24 . The adjusting bolt 26 transversely penetrates the side wall of the instrument body 1 and is rotatably connected to the instrument body 1 through a thread.

[0027] By arranging the adjusting bolt 26 and the fixing frame 24 to cooperate with each other, the position of the fixing frame 24 can be adjusted by rotating the adjusting bolt 26 so as to cooperate with the pulse transmitter 23 to clamp the fluid pipeline.

[0029] The adjusting motor 221 is provided to drive the double-headed threaded rod 222 , thereby driving the outer threaded sleeve 223 to move, thereby driving the connecting rod 224 to move.

[0030] In this embodiment, a sliding groove 27 is opened on the side of the regulating box 22, and the connecting rod 224 passes through the sliding groove 27 horizontally and is slidably connected to the sliding groove 27. The side of the connecting rod 224 and the side of the pulse transmitter 23 are fixedly installed.

[0031] The connecting rod 224 is limited by setting the sliding groove 27 so that the connecting rod 224 can move smoothly inside the sliding groove 27 and drive the pulse transmitter 23 to move at the same time.

[0032] In this embodiment, the threads of the two ends of the double-threaded rod 222 are in opposite directions, and a limit plate is provided on the side of the connecting rod 224 located inside the sliding groove 27 to prevent rotation.

After the measurement is completed, the data display 42 shows the data measured at the current measurement position.

[0040] In addition, the adjusting motor 221 is started, and the output shaft of the adjusting motor 221 drives the double-headed threaded rod 222 to rotate.

Therefore, the threaded sleeve 223 moves laterally on the outside of the double-headed threaded rod 222. The lateral movement of the threaded sleeve 223 drives the movement of the connecting rod 224. The movement of the connecting rod 224 drives the pulse transmitter 23 to move on the side of the fluid pipeline through the ball bearing, thereby changing the relative position of the pulse transmitter 23 and the fluid pipeline, and then the pulse transmitter 23 is used to transmit pulses for measurement again. After changing the relative position of the pulse transmitter 23 and the pipeline for many times, more accurate measurement data is obtained, which solves the problem that the traditional flow integrator may have low data accuracy due to the fixed measuring equipment during measurement.
