Description

A 0.2L sampling electronic smart gas meter Technical Field

[0001] This invention relates to a 0.2L sampling electronic smart gas meter, belonging to the field of gas equipment technology. Background Technology

[0002] With the large-scale promotion and application of urban pipelines, the coverage of gas is wide, involving more and more users. Gas meters are a key component of normal home gas systems, so the safety of gas use is also a key focus for major gas companies. According to statistics, the incidence of gas safety incidents in my country is increasing every year, and gas companies in major cities are seeking higher accuracy metering. Some areas require solutions that support compensation and can detect dangerous gas usage (constant flow, minor leaks, etc.) during gas use.

[0003] Currently, the pulse equivalent of gas meters both domestically and internationally is mainly 0.01m. 3 The 10L sampling accuracy is insufficient to meet current market and safety requirements for gas usage, and cannot accurately detect gas consumption. A newly designed 0.2L pulse sampling smart gas meter better meets market demands. This pulse accuracy is high, enabling better detection of even minor leaks. In modern society, safety-oriented smart gas meters, with their user-friendly design, will undoubtedly see wider application in the gas industry. This has significant practical implications for strengthening technological innovation and improving the application of smart gas meters.

[0004] Summary of the Invention

[0005] The technical problem this invention aims to solve is how to detect the gas usage of gas meters both domestically and internationally with higher accuracy.

[0006] To address the aforementioned technical problems, this invention provides a 0.2L sampling electronic smart gas meter with high pulse accuracy, enabling better detection of minute leaks and other issues.

[0007] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0008] A 0.2L sampling electronic smart gas meter includes a gas meter base, a metering component, and a main control circuit board. The metering component is detachably installed inside the gas meter base to realize 0.2L pulse sampling and metering of the flowing gas. The main control circuit board is detachably installed on the gas meter base to cover the metering component and realize pulse sampling and metering as well as control of the gas meter.

[0009] Preferably, the metering component includes a 30-tooth small magnetic ring, a 10-tooth sampling wheel, and a magnet. The 30-tooth small magnetic ring is rotated and mounted on the gas meter base by the gas flowing through the gas meter. The 10-tooth sampling wheel is rotated and mounted on the gas meter base and meshes with the 30-tooth small magnetic ring. Two magnets are provided, and the two magnets are evenly spaced around the circumference of the 10-tooth sampling wheel on the side wall of the 10-tooth sampling wheel away from the gas meter base.

[0010] Preferably, the main control circuit board includes a main control board, Hall sensor one, Hall sensor two, and Hall sensor three. Hall sensor one and Hall sensor two are disposed on the side of the main control board facing the gas meter base for sampling and measurement, and Hall sensor three is disposed on the side of the main control board away from the gas meter base for anti-magnetic function.

[0011] Preferably, the Hall sensor is connected to the valve signal inside the gas meter.

[0012] Preferably, the gas meter is equipped with a temperature sensor or a temperature and pressure sensor.

[0013] The present invention provides a 0.2L sampling electronic smart gas meter, which has the following advantages:

[0014] (1) In this invention, by setting up a 30-tooth magnetic ring, a 10-tooth sampling wheel and two magnets, the gas sampling signal flowing through the gas meter is divided into 0.2L portions, thereby achieving 0.2L pulse sampling measurement. The pulse accuracy is high, which can better detect minor leaks and other situations.

[0015] (2) In this invention, two Hall sensors are set on the side of the main control board facing the gas meter base for sampling and measurement. The dual Hall sensors better ensure the stability and reliability of the measurement. The Hall sensor three set on the side of the main control board away from the gas meter base is used for antimagnetic protection. When the gas meter is attacked by a magnetic field, the gas meter closes the valve, which can ensure accurate measurement.

[0016] (3) In this invention, by equipping the valve in the body of the instrument with a temperature sensor or a temperature and pressure sensor, electronic temperature compensation or electronic temperature and pressure compensation can be selected according to the needs, and then combined with 0.2L sampling metering, so that the compensation metering accuracy is higher and more accurate.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Referring to Figures 1-5, a 0.2L sampling electronic smart gas meter includes a gas meter base 1, a metering component 2, and a main control circuit board 3. The metering component 2 is detachably installed in the gas meter base 1 to realize 0.2L pulse sampling and metering of the gas flowing through it. The main control circuit board 3 is detachably installed on the gas meter base 1 by bolts to cover the metering component 2 and realize pulse sampling and metering and control of the gas meter.

[0026] Referring to Figures 1-3, the metering component 2 includes a 30-tooth small magnetic ring 21, a 10-tooth sampling wheel 22, and a magnet 23. Both the 30-tooth small magnetic ring 21 and the 10-tooth sampling wheel 22 are rotatably mounted on the inner bottom wall of the gas meter base 1 via a rotating shaft. The 10-tooth sampling wheel 22 meshes with the 30-tooth small magnetic ring 21. Two magnets 23 are embedded and preferably 4*4.5 mm in size. The two magnets 23 are evenly spaced around the circumference of the 10-tooth sampling wheel 22 on the side wall of the 10-tooth sampling wheel 22 facing away from the gas meter base 1. In use, the gas passes through the gas meter and drives the 30-tooth small magnetic ring 21 to rotate. The 30-tooth small magnetic ring 21 drives the 10-tooth sampling wheel 22. The rotation volume of the 1.2L gas meter is 1.2L, that is, one rotation of the 30-tooth small magnetic ring 21 represents 1.2L. After being converted by the 10-tooth sampling wheel 22, one rotation of the 10-tooth sampling wheel 22 represents 0.4L. The 10-tooth sampling wheel 22 is inlaid with two 4*4.5 magnets 23, that is, the sampling signal is divided again, that is, each part is 0.2L, thus realizing 0.2L pulse sampling measurement.

[0027] Referring to Figures 4 and 5, the main control circuit board 3 includes a main control board 31, a Hall sensor 1 32, a Hall sensor 2 33, and a Hall sensor 34. Hall sensors 1 32 and 2 33 are integrated and installed on the side of the main control board 31 facing the gas meter base 1 for sampling and metering. The dual Hall sensors can better ensure the stability and reliability of the metering. Hall sensor 34 is integrated and installed on the side of the main control board 31 away from the gas meter base 1 for anti-magnetic function. Hall sensor 34 is also connected to the valve inside the gas meter (not shown in the figure). When it receives a magnetic field attack, the gas meter closes the valve, which can ensure accurate metering. In this embodiment, the integration and installation of the Hall sensors and the sampling and metering principle are existing technologies and will not be described in detail.

[0028] Furthermore, a temperature sensor or temperature-pressure sensor (not shown in the figure) is integrally embedded in the valve of the gas meter through injection molding. The temperature sensor or temperature-pressure sensor is connected to the main control circuit board 3 via an adapter cable. The program of the main control circuit board 3 can be configured according to requirements, and electronic temperature compensation or electronic temperature-pressure compensation can be selected according to customer needs to perform compensation metering. Combined with 0.2L sampling metering, the compensation metering accuracy is higher and more accurate. In this embodiment, the embedding and connection methods of the gas meter valve and the temperature sensor or temperature-pressure sensor are all existing technologies and will not be described in detail.
