[0030] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0031] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0032] The gas flowmeter standard table method device is used for calibrating or periodical testing of the gas flowmeter. In the related art, the calibration or periodical testing of the gas flowmeter is mainly carried out in the laboratory, that is, the gas flowmeter standard table method device is arranged in the laboratory, and the gas flowmeter standard table method device mainly includes a plurality of testing modules for testing different specifications of the gas flowmeter. The plurality of testing modules adopt a flat structure, each testing module includes a plurality of pipelines, and the plurality of pipelines are fixedly connected through flanges and threads.

[0033] However, due to the large volume and difficult disassembly of the gas flowmeter standard table method device, the gas flowmeter standard table method device is only suitable for fixed scenes such as laboratories, and cannot be applied to scenes that need to be tested outside. If the gas flowmeter is to be tested by using the gas flowmeter standard table method device in the related art, the gas flowmeter needs to be sent to the laboratory, which takes a long time to go back and forth, thereby reducing the testing efficiency of the gas flowmeter. In addition, the gas flowmeter standard table method device in the laboratory usually has a fixed testable flow range, and it is difficult to expand the flow range of the gas flowmeter standard table method device, thereby limiting the application range of the gas flowmeter standard table method device.

[0034] Therefore, the gas flowmeter standard table method device provided by the embodiments of the present application is provided, wherein the flowmeter, the fan, the first pipeline and the second pipeline are connected in a detachable manner. When it is necessary to go out for calibration, for the to-be-calibrated meter to be calibrated, the flowmeter corresponding to the range, the fan corresponding to the power, and the first pipeline and the second pipeline corresponding to the caliber are selected. The gas flowmeter standard table method device can be quickly assembled at the calibration site, and after the calibration work is completed, the gas flowmeter standard table method device can be quickly disassembled, thereby facilitating the user to flexibly cope with the scene of going out for calibration.

[0035] The specific implementation of the gas flowmeter standard table method device provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] Referring to Figure 1 With Figure 2 As shown in FIG. 1, the embodiments of the present application provide a gas flowmeter standard table method device 10, which comprises a flowmeter assembly 100, a fan assembly 200 and a pipeline assembly 300. The flowmeter assembly 100 comprises at least one flowmeter 110, which is configured to calibrate the flow of a meter to be calibrated 20. The fan assembly 200 comprises at least one fan 210, which is configured to provide airflow. The pipeline assembly 300 comprises a first pipeline 310 and a second pipeline 320. The first end of the first pipeline 310 is detachably connected to the flowmeter 110, and the second end of the first pipeline 310 is configured to be detachably connected to the first end of the meter to be calibrated 20. The first end of the second pipeline 320 is configured to be detachably connected to the second end of the meter to be calibrated 20, and the second end of the second pipeline 320 is detachably connected to the fan 210.

[0037] In the present application, the gas flowmeter standard table method device 10 calibrates the meter to be calibrated 20 (such as a diaphragm gas meter) based on the standard method. The main principle is to measure the speed and pressure of the fluid passing through the flowmeter 110 to determine the flow of the meter to be calibrated 20. The fan 210 can be used to provide negative pressure to generate airflow, and the first pipeline 310 and the second pipeline 320 can be used to clamp the meter to be calibrated 20, so that the fan 210 drives the airflow to flow along the flowmeter 110, the first pipeline 310, the meter to be calibrated 20 and the second pipeline 320 in sequence, and finally the flow of the meter to be calibrated 20 is obtained.

[0038] In order to facilitate the gas flowmeter standard meter method device 10 to go out for verification, the flowmeter 110 and the first pipeline 310, the first pipeline 310 and the second pipeline 320, the second pipeline 320 and the fan 210 are detachably connected, so that when it is necessary to go out for verification, the separated flowmeter 110, the first pipeline 310, the second pipeline 320 and the fan 210 are transported to the verification site, and then the flowmeter 110 and the first pipeline 310 are installed, the second pipeline 320 and the fan 210 are installed, and finally the meter 20 to be tested is installed between the first pipeline 310 and the second pipeline 320. Alternatively, the meter 20 to be tested can be installed between the first pipeline 310 and the second pipeline 320, and then the flowmeter 110 and the first pipeline 310 are installed, and the fan 210 and the second pipeline 320 are installed. In this way, the gas flowmeter standard meter method device 10 can be conveniently and quickly assembled as a whole, and then the meter 20 to be tested can be conveniently and quickly verified. After the verification is completed, the gas flowmeter standard meter method device 10 can be conveniently and quickly disassembled into scattered parts, so as to reduce the volume of the gas flowmeter standard meter method device 10, and then facilitate the gas flowmeter standard meter method device 10 to be transported to different verification sites. Moreover, after the verification is completed, the result of the verification can be quickly obtained, the time required for verification is saved, and the verification efficiency of the gas flowmeter standard meter method device 10 is improved.

[0039] Because different specifications of the meter 20 to be tested need to be connected to different diameters of the first pipeline 310 and the second pipeline 320, before going out for verification, the first pipeline 310 and the second pipeline 320 of the corresponding diameter can be selected according to the specification of the meter 20 to be tested. In addition, the flowmeter 110 and the fan 210 required by different specifications of the meter 20 to be tested are also different, so before going out for verification, the flowmeter 110 of the corresponding range and the fan 210 of the corresponding power can be selected according to the specification of the meter 20 to be tested. In this way, the gas flowmeter standard meter method device 10 can be flexibly configured according to the verification requirements, and will not be limited to a certain fixed configuration, thereby expanding the use range of the gas flowmeter standard meter method device 10.

[0040] The gas flowmeter standard table method device 10 provided by the embodiment of the present application comprises a flowmeter assembly 100, a fan assembly 200 and a pipeline assembly 300. The flowmeter assembly 100 comprises a flowmeter 110, the fan assembly 200 comprises a fan 210, and the pipeline assembly 300 comprises a first pipeline 310 and a second pipeline 320. The flowmeter 110 is arranged to calibrate the to-be-calibrated table 20, the fan 210 is arranged to provide airflow, and the first pipeline 310 and the second pipeline 320 are arranged to clamp the to-be-calibrated table 20. The flowmeter 110 and the first pipeline 310, the first pipeline 310 and the second pipeline 320, and the second pipeline 320 and the fan 210 are detachably connected, so as to flexibly configure the gas flowmeter standard table method device 10 according to the specifications of the to-be-calibrated table 20, facilitate disassembly and assembly of each part of the gas flowmeter standard table method device 10, and further facilitate the gas flowmeter standard table method device 10 to cope with the scene requirements of outgoing calibration. Therefore, the gas flowmeter standard table method device 10 provided by the embodiment of the present application is easy to disassemble and assemble and flexible to expand.

[0041] With reference to Figure 1 And Figure 2 As shown in the figure, in a possible implementation, the gas flowmeter standard table method device 10 further comprises a first quick connection assembly 400, and a first end of the first pipeline 310 is connected with the flowmeter 110 through the first quick connection assembly 400.

[0042] In this way, because the first quick connection assembly 400 is arranged between the first pipeline 310 and the flowmeter 110, the first end of the first pipeline 310 can be quickly disassembled or assembled with the flowmeter 110, thereby improving the disassembly and assembly convenience of the gas flowmeter standard table method device 10.

[0043] In specific implementation, the first quick connection assembly 400 comprises a first quick connector, a first clamping piece and a second clamping piece. The first quick connector has a first connecting end and a second connecting end at two ends respectively. The flowmeter 110 has a first interface. The inner diameter of the first connecting end is matched with the inner diameter of the first interface. The first connecting end is connected with the first interface through the first clamping piece. The inner diameter of the second connecting end is matched with the inner diameter of the first pipeline 310. The second connecting end is connected with the first pipeline 310 through the second clamping piece.

[0044] In this way, the first pipeline 310 and the flowmeter 110 can be connected through the first quick connector, and the flowmeter 110 and the first quick connector can be detachably connected through the first clamping piece, and the first pipeline 310 and the first quick connector can be detachably connected through the second clamping piece, thereby realizing detachable connection of the flowmeter 110 and the first pipeline 310 through the first quick connector, the first clamping piece and the second clamping piece.

[0045] It should be noted that, in order to improve the sealing between the first connecting end and the first interface, and the sealing between the second connecting end and the first pipeline 310, a sealing member can be arranged between the first connecting end and the first interface, and between the second connecting end and the first pipeline 310, so as to seal the gap between the first connecting end and the first interface, and the gap between the second connecting end and the first pipeline 310.

[0046] Referring to Figure 1 With Figure 2 As shown in a possible implementation, the gas flowmeter standard table method device 10 further comprises: a second quick connection assembly 500, the second end of the second pipeline 320 is connected with the fan 210 through the second quick connection assembly 500.

[0047] In this way, by arranging the second quick connection assembly 500 between the second pipeline 320 and the fan 210, the second pipeline 320 and the fan 210 can be quickly installed, thereby improving the disassembly and assembly convenience of the gas flowmeter standard table method device 10.

[0048] Referring to Figures 1 to 3 As shown in a possible implementation, the second quick connection assembly 500 comprises a second quick connector 510, a third clamping member 520 and a fourth clamping member 530, the second quick connector 510 has a third connecting end and a fourth connecting end at two ends respectively, the fan 210 has a second interface, the inner diameter of the third connecting end is matched with the inner diameter of the second interface, the third connecting end is connected with the second interface through the third clamping member 520, and the inner diameter of the fourth connecting end is matched with the inner diameter of the second pipeline 320, the fourth connecting end is connected with the second pipeline 320 through the fourth clamping member 530.

[0049] In this way, the second pipeline 320 and the fan 210 can be communicated through the second quick connector 510, and the second quick connector 510 and the fan 210 can be detachably connected through the third clamping member 520, and the second pipeline 320 and the second quick connector 510 can be detachably connected through the fourth clamping member 530, thereby realizing the detachable connection of the second pipeline 320 and the fan 210 through the second quick connector 510, the third clamping member 520 and the fourth clamping member 530.

[0050] Among them, the structure of the first quick connector and the second quick connector 510 can be the same, that is, the first quick connector and the second quick connector 510 can each comprise a connecting pipe segment and connecting ends at both ends of the connecting pipe segment, and since the sizes of the first interface and the second interface are inconsistent, the inner diameters of the first connecting end and the third connecting end are different. However, for the same type of test table 20, the inner diameters of the first pipeline 310 and the second pipeline 320 are consistent, and at this time, the inner diameters of the second connecting end and the fourth connecting end can be consistent.

[0051] It can be understood that for the first pipe 310 with different inner diameters, a plurality of second connecting ends with different inner diameters can be designed, thereby forming first quick connectors of different specifications, thereby facilitating flexible configuration of the gas flowmeter standard table method device 10. For the second pipe 320 with different inner diameters, a plurality of fourth connecting ends with different inner diameters can be designed, thereby forming second quick connectors 510 of different specifications, thereby facilitating flexible configuration of the gas flowmeter standard table method device 10.

[0052] In addition, in order to improve the sealing between the third connecting end and the second interface, the sealing between the fourth connecting end and the second pipe 320, a sealing member can be arranged between the third connecting end and the second interface, and between the fourth connecting end and the second pipe 320, thereby sealing the gap between the third connecting end and the second interface, and the gap between the fourth connecting end and the second pipe 320.

[0053] Referring to Figure 1 and Figure 2 As shown in a possible implementation, the gas flowmeter standard table method device 10 further includes two third quick connection assemblies 600, the second end of the first pipe 310 is connected to the tested table 20 through the third quick connection assembly 600, and the first end of the second pipe 320 is connected to the tested table 20 through the third quick connection assembly 600.

[0054] In this way, the two ends of the tested table 20 can be detachably connected to the first pipe 310 and the second pipe 320 through the third quick connection assembly 600, thereby facilitating quick clamping of the tested table 20 between the first pipe 310 and the second pipe 320.

[0055] In a specific implementation, the third quick connection assembly 600 includes a third quick connector and a fifth clamping member, the two ends of the third quick connector are respectively provided with a fifth connecting end and a sixth connecting end, the fifth connecting end is connected to the first pipe 310 through the fifth clamping member, or the fifth connecting end is connected to the second pipe 320 through the fifth clamping member, and the sixth connecting end is threadedly connected to the tested table 20.

[0056] In this way, the second end of the first pipe 310 can be detachably connected to the tested table 20 through the fifth connecting end and the fifth clamping member, the first end of the second pipe 320 can be detachably connected to the tested table 20 through the fifth connecting end and the fifth clamping member, thereby enabling the tested table 20 to be detachably clamped between the first pipe 310 and the second pipe 320 through the two third quick connection assemblies 600.

[0057] The sixth connecting end can be a flange plate matched with the tested table 20, thereby enabling the sixth connecting end to be connected to the tested table 20 through threads.

[0058] Exemplarily, the first clamping member, the second clamping member, the third clamping member 520, the fourth clamping member 530 and the fifth clamping member can all be three-petal clamps.

[0059] Referring to Figure 2 As shown in the drawings, in some embodiments, the flowmeter assembly 100 comprises a first adapter 120 and two flowmeters 110, the first adapter 120 having one first outlet and two first inlets, the first outlet being detachably connected to the first pipeline 310, and the two first inlets being respectively detachably connected to the two flowmeters 110.

[0060] And / or, the fan assembly 200 comprises a second adapter 220 and two fans 210, the second adapter 220 having one second inlet and two second outlets, the second inlet being detachably connected to the second pipeline 320, and the two fans 210 being respectively connected to the two second outlets.

[0061] It should be noted that for a larger flow rate of the tested meter 20, one flowmeter 110 cannot meet the calibration range, and two flowmeters 110 can be provided, which can be connected to the first pipeline 310 through a first adapter 120. Similarly, for a larger flow rate of the tested meter 20, one fan 210 provides a smaller airflow, which is difficult to meet the requirements, and two fans 210 can be provided, which can be connected to the second pipeline 320 through a second adapter 220.

[0063] That is, before calibration, the control assembly 700 can be used to control the fans 210, so that the fans 210 provide the required airflow, and the control assembly 700 can also supply power to the flowmeters 110 and the fans 210. During the calibration process, the data obtained by the flowmeters 110 can be transmitted to the control assembly 700, and the control assembly 700 can process the data on site to obtain the flow rate of the tested meter 20. In this way, the calibration time of the tested meter 20 is saved, and the calibration efficiency of the gas flowmeter standard meter method device 10 is improved.

[0064] In some embodiments, the gas flowmeter standard meter method device 10 further comprises two electrical connectors, both of which are electrically connected to the control assembly 700, one of which is electrically connected to the flowmeters 110, and the other of which is electrically connected to the fans 210.
