Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas flow meter technology, specifically to an intelligent gas flow meter protection device. Background Technology
[0002] A gas flow meter is a device that monitors the volume or mass of gas passing through a pipeline. Intelligent gas flow meter protection devices are primarily designed to ensure the stable and reliable operation of the gas flow meter during use. Gas flow meters are commonly used to measure gas flow and are widely applied in industries such as natural gas, liquefied petroleum gas (LPG), and coal gas. Gas flow meter protection devices are mainly used to extend the service life of the flow meter.
[0003] The existing technology has the following shortcomings: Application number 202220514582.5 proposes a protective device for an intelligent gas flow meter, specifically relating to the field of gas flow meter technology. Existing protective covers for gas flow meters are typically fitted onto the surface of the flow meter during use, resulting in unstable installation. Furthermore, current gas flow meters are fixed to the target pipeline via flanges, requiring the removal of numerous bolts when the flow meter is damaged. The proposed device addresses this by providing limiting grooves on both sides of the gas flow meter body, movably mounting a protective cover on the outside of the gas flow meter body, and installing a pipe below the gas flow meter body. The protective cover contains a fixing component, and the gas flow meter body also has an installation component below it. By setting the fixing component, the position between the protective cover and the gas flow meter body is easily fixed, preventing the protective cover from falling off during use. The installation component also facilitates the disassembly of the gas flow meter body during use, enabling later maintenance or replacement.
[0004] The aforementioned device only provides physical protection for the external components of the gas flow meter. Since current gas flow meters are made of metal and have a relatively stable structure, their need for external physical protection is minimal. The structure cannot prevent temperature fluctuations in the environment in which the gas flow meter operates. Temperature changes affect the density and viscosity of the gas, leading to measurement errors. In low-temperature environments, the gas density increases, resulting in higher measured values; conversely, in high-temperature environments, the gas viscosity decreases, potentially leading to lower measured values. Therefore, the aforementioned protection device cannot protect the flow meter from temperature variations. Furthermore, as gas flows through the pipe, friction and separation effects cause gas molecules to acquire static charges. These static charges increase when the pipe friction area is large or the separation speed is fast, interfering with gas flow measurement and increasing measurement errors. Therefore, electrostatic protection for the gas flow meter can be further improved. Utility Model Content

[0015] 1. This intelligent gas flow meter protection device, by setting up a flow meter body, an inner cavity, and a heat insulation component, when there is a large difference between the ambient temperature of the flow meter body and the internal temperature of the flow meter body, the heat insulation component can prevent the external temperature from affecting the internal temperature of the flow meter body, keep the internal temperature of the flow meter body stable, avoid large fluctuations, and prevent the temperature from affecting the monitoring accuracy of the flow meter.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4In this embodiment: a smart gas flow meter protection device includes a flow meter body 1 and a transmission device 5. Flanges 2 are provided at both ends of the flow meter body 1. A connecting component 3 is provided on the flow meter body 1. A smart flow calculator 4 is provided on the connecting component 3. A chain 6 is provided at the bottom of the transmission device 5. An inner cavity 7 is opened between the inner wall and the outer side of the flow meter body 1. A heat insulation component 8 is provided in the inner cavity 7.
[0024] The inner cavity 7 facilitates the heat insulation component 8 to surround the flow meter body 1 after filling;
[0025] The conduction device 5 includes a conduction mechanism 501, a connecting rod 502, and a carbon black coating 503. The connecting rod 502 is provided between the conduction mechanisms 501, and the carbon black coating 503 is provided on the inner wall of the conduction mechanism 501.
[0026] The carbon black coating 503 can improve the stability of electrostatic conduction between the outer side of the flowmeter body 1 and the conduction mechanism 501.
[0027] In this embodiment, there are two sets of flanges 2, which are respectively threaded to both ends of the flow meter body 1. The connecting component 3 is fixedly installed on the top of the flow meter body 1, and the intelligent flow calculator 4 is fixedly installed on the top of the connecting component 3.
[0028] Specifically, the intelligent flow meter 4 can monitor the flow rate of the circulating gas in conjunction with the corresponding sensor.
[0029] In this embodiment, there are six sets of transmission mechanisms 501. The transmission mechanisms 501 are fixedly connected by connecting rods 502. Both the transmission mechanism 501 and the connecting rods 502 are arc-shaped. The transmission mechanism 501 and the connecting rods 502 form a ring and are adapted to the flow meter body 1.
[0030] Specifically, the connecting rod 502 can be used to connect the transmission mechanism 501, ensuring the stability of the transmission mechanism 501.
[0031] In this embodiment, the conduction mechanism 501 is closely attached to the outside of the flow meter body 1, the inner cavity 7 is annular, the heat insulation component 8 is adapted to the inner cavity 7, the heat insulation component 8 is filled in the inner cavity 7 and is specifically made of aerogel, there are two sets of chains 6 and they are fixed on the conduction mechanism 501 at the bottom position, and the end of the chain 6 is in contact with the ground.
[0032] Specifically, the chain 6 can transfer static electricity from the conduction mechanism 501 to the ground, and the heat insulation component 8 can keep the internal temperature of the flow meter body 1 stable, preventing the flow meter's monitoring accuracy from being affected by temperature.
[0033] The working principle and usage process of this utility model are as follows: In actual use, the flow meter device is connected to the corresponding gas pipeline using a conventional installation method. When there is a large difference between the ambient temperature of the flow meter body 1 and the internal temperature of the flow meter body 1, the aerogel insulation component 8 can surround the flow meter body 1 in the inner cavity 7 to prevent the external temperature from affecting the internal temperature of the flow meter body 1. At the same time, the internal temperature of the flow meter body 1 will not be transmitted to the outside, so that the internal temperature of the flow meter body 1 remains stable and avoids large fluctuations. This prevents the temperature from affecting the monitoring accuracy of the flow meter. When the gas flows, if the friction area of the gas pipeline is large or the separation speed is fast, the static charge will increase and cause static electricity. The static electricity will exist on the surface of the metal flow meter body 1. At the same time, the static electricity is transmitted to the conduction mechanism 501 under the action of the carbon black coating 503, and finally transmitted to the ground through the chain 6 to form a grounding effect. This can prevent static electricity accumulation and improve the static electricity protection effect of the flow meter body 1.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
