[0029] Embodiment 1:

[0030] like Figure 1-Figure 3 As shown, the present invention provides a natural gas dedicated valve monitoring system 1, comprising: a liquid generating device 10, a water receiving tray 20 and a delivery pump 30, the liquid generating device 10 is arranged above the valve and connected to the natural gas pipeline, the liquid generating device 10 is suitable for producing soapy water, the liquid generating device 10 is provided with a water outlet, the water outlet is suitable for discharging soapy water to the natural gas pipeline and / or the valve, the water receiving tray 20 is arranged below the valve and connected to the natural gas pipeline, the water receiving tray 20 is suitable for receiving liquid dropped from the valve and / or the natural gas pipeline, the delivery pump 30 is respectively connected to the liquid generating device 10 and the water receiving tray 20, and the delivery pump 30 is suitable for driving the liquid in the water receiving tray 20 to enter the liquid generating device 10.

[0031] In some embodiments, the liquid generating device 10 is installed above the valve and connected to the natural gas pipeline. The function of the liquid generating device 10 is to produce soapy water, which is used to detect whether the natural gas is leaking. The liquid generating device 10 is provided with a water outlet, which is used to discharge the soapy water to the area that needs to be tested. The water receiving tray 20 is located below the valve and connected to the natural gas pipeline. The function of the water receiving tray 20 is to collect any liquid dripping from the liquid generating device 10 or the valve to prevent the liquid from leaking into the environment. The delivery pump 30 connects the liquid generating device 10 and the water receiving tray 20. The task of the delivery pump 30 is to pump the liquid collected in the water receiving tray 20 back to the liquid generating device 10, thereby forming a circulation system to reduce resource waste and keep the environment clean.

[0032] It is worth noting that the water outlet is suitable for discharging soapy water into the natural gas pipeline and / or the valve. Here, it can be that the water outlet discharges soapy water into the natural gas pipeline, and the discharged soapy water can flow through the connection between the valve and the natural gas pipeline; here, it can also be that the water outlet discharges soapy water into the valve, and the discharged soapy water can cover the valve; here, it can also be that the water outlet discharges soapy water into the natural gas pipeline and the valve at the same time, and there is no limitation here.

[0033] It is understood that when soapy water is sprayed onto a possible leak point, if there is a small leak, natural gas will escape and pass through the soapy water film, causing the soapy water to foam. The user can determine whether there is a leak by observing whether there are bubbles. The used soapy water is collected by the water receiving tray 20 and then pumped back into the liquid generating device 10 by the delivery pump 30 for reuse.

[0034] According to the natural gas dedicated valve monitoring system 1 of the present invention, the monitoring system 1 of the present application has a simple structure and a simple principle, can realize efficient monitoring of valves, and can also directly target difficult-to-detect parts. Moreover, by recycling soapy water, the impact of chemical substances on the environment is reduced and the consumption of water resources is reduced. In addition, the recycling of soapy water not only saves material costs, but also reduces the extra workload required to clean up leaked liquids.

[0035] Embodiment 2:

[0036] In this embodiment, based on the first embodiment, the liquid generating device 10 includes: a shell 11 and two ears 12. The shell 11 is provided with a receiving cavity suitable for receiving soapy water. The two ears 12 are respectively connected to the shell 11 and are spaced apart from each other in the width direction. The two ears 12 are respectively formed with receiving grooves open toward each other. The two receiving grooves jointly define a mounting hole. The mounting hole cooperates with the natural gas pipeline to connect the liquid generating device 10 to the natural gas pipeline.

[0037] In some embodiments, the shell 11 is the main part of the liquid generating device 10. A accommodating cavity is provided inside the shell 11, which is used to store soapy water for detecting leaks. Two ears 12 are connected to the shell 11, and the two ears 12 are spaced apart from each other in the width direction. Each ear 12 has a receiving groove open to each other. The two receiving grooves together form a mounting hole. The mounting hole is specially designed to cooperate with a natural gas pipeline. The mounting hole allows the liquid generating device 10 to be directly installed on the pipeline, thereby ensuring the stability and positioning accuracy of the device.

[0038] It can be understood that by directly fixing the liquid generating device 10 on the natural gas pipeline, it can be ensured that the liquid generating device 10 will not move or fall off during the entire detection process, thereby improving the reliability of the monitoring system 1. Moreover, the liquid generating device 10 can be firmly installed at the position to be monitored without the need for complicated assembly steps. At the same time, the design of the support ear 12 and the receiving groove takes into account natural gas pipelines of different diameters, so that the monitoring system 1 can be used on a variety of different pipeline sizes, increasing the versatility and flexibility of the monitoring system 1. Of course, integrating the liquid storage (containing chamber) and the installation mechanism (support ear 12 and mounting hole) into one component simplifies the overall structure and also facilitates maintenance and replacement.

[0039] According to some embodiments of the present invention, the support ear 12 is provided with a liquid passage, which is connected to the accommodating cavity, and the water outlet includes: a plurality of first water outlets, the plurality of first water outlets are respectively arranged on the inner wall of the receiving groove, and the plurality of first water outlets are respectively connected to the liquid passage, and the plurality of first water outlets are arranged at intervals from each other along the circumference of the natural gas pipeline.

[0040] In some embodiments, a liquid passage is provided on the support ear 12, and the liquid passage is connected to the accommodating chamber inside the shell 11, so that the soapy water in the accommodating chamber can flow through the liquid passage, and a plurality of first water outlets are provided on the inner wall of the receiving groove of each support ear 12, and the plurality of first water outlets are spaced apart from each other along the circumference of the natural gas pipeline. The first water outlet is directly connected to the liquid passage, allowing the soapy water to flow out of the accommodating chamber through the liquid passage, and finally be discharged from each first water outlet, thereby ensuring that the soapy water can be evenly sprayed along the entire circumferential direction of the pipeline, thereby covering the circumferential surface of the pipeline, so as to realize the connection between the monitoring valve and the natural gas pipeline.

[0041] It can be understood that by arranging multiple first water outlets along the circumference of the pipe, it is ensured that the soapy water can be evenly applied to the entire tested area, thereby improving the accuracy of leak detection. Moreover, since the first water outlets are distributed around the pipe, even tiny leaks will not be missed, thereby ensuring the integrity of the detection. Of course, the design of multiple first water outlets can also help control the flow rate and flow of soapy water to avoid releasing too much soapy water at one time, causing waste or affecting the observation effect.

[0042] Embodiment three:

[0043] In this embodiment, based on the second embodiment, the inner wall of the receiving groove is provided with a plurality of guide grooves 121 extending in the height direction, and the plurality of guide grooves 121 correspond one by one to a plurality of first water outlets, respectively, and the first water outlets are provided on the bottom walls of the corresponding guide grooves 121 .

[0044] In some embodiments, a plurality of guide grooves 121 extending along the height direction are provided on the inner wall of the receiving groove. The guide grooves 121 are designed to guide the soapy water discharged from the first water outlet to flow in a specific direction. Each guide groove 121 corresponds one-to-one to a first water outlet, and the first water outlet is located at the bottom wall of the corresponding guide groove 121, thereby ensuring that the soapy water immediately enters the guide groove 121 once it flows out from the water outlet, thereby being directed to a specific position.

[0045] Therefore, through the design of the guide groove 121, the flow direction of the soapy water can be controlled more accurately, ensuring that the soapy water can accurately cover the area that needs to be inspected, avoiding the problem of soapy water directly dripping or uneven dispersion. Moreover, the guide groove 121 helps to evenly distribute the soapy water on the surface of the pipe, especially for vertically installed pipes, to prevent the soapy water from concentrating in a certain part due to gravity, ensuring that all leakage points on the entire circumference can be effectively detected.

[0046] Of course, since the soapy water is effectively guided to the desired location, unnecessary overflow or waste is reduced and resource utilization is improved. In addition, the existence of the guide groove 121 allows the soapy water to form a stable flow path, and it is easier to form obvious bubbles when encountering a leak, which is convenient for users to observe and judge. At the same time, even in different installation angles or environments, the guide groove 121 can ensure that the soapy water flows along the predetermined path, thereby enhancing the applicability and reliability of the monitoring system 1.

[0047] It is worth mentioning that a stop protrusion is defined between two adjacent guide grooves 121, and the free end of the stop protrusion is suitable for abutting against the outer peripheral wall of the natural gas pipeline. Therefore, the arrangement of multiple stop protrusions can increase the friction between the support ear 12 and the natural gas pipeline, thereby improving the matching effect between the support ear 12 and the natural gas pipeline, and further improving the connection strength between the liquid producing device 10 and the natural gas pipeline.

[0048] At the same time, the provision of the guide groove 121 can prevent the soapy water from being unable to be discharged when the support ear 12 is in close contact with the natural gas pipeline, thereby improving the working stability of the monitoring system 1.

[0049] According to some embodiments of the present invention, one end of the two ears 12 on the same side is respectively connected to the shell 11, and the other end of the two ears 12 on the same side can be selectively moved toward or away from each other. The other end of the two ears 12 on the same side is respectively provided with through holes, and the screw 13 passes through the two through holes and cooperates with the nut to fix the position of the two ears 12.

[0050] In some embodiments, the two ears 12 are connected to the housing 11 respectively, and the free ends of the two ears 12 are respectively provided with through holes, and the screw 13 passes through the two through holes in sequence and cooperates with the nut. When the liquid generating device 10 needs to be fastened to the natural gas pipeline, the screw 13 is rotated to make the free ends of the two ears 12 approach each other, so that the two receiving grooves approach each other and respectively press against the outer peripheral wall of the natural gas pipeline, so as to achieve the fastening of the liquid generating device 10 to the natural gas pipeline. Therefore, the above-mentioned configuration makes the installation and disassembly of the liquid generating device 10 simpler, and improves the disassembly efficiency of the monitoring system 1.

[0051] Embodiment 4:

[0052] In this embodiment, based on the second embodiment, the water outlet further includes: a plurality of second water outlets, which are respectively arranged on the shell 11 and connected to the accommodating cavity; wherein the monitoring system 1 further includes: a flexible guide member 40, which is constructed to correspond one to one to the plurality of second water outlets, one end of the flexible guide member 40 is connected to the corresponding second water outlet, and the other end of the flexible guide member 40 is connected to the valve.

[0053] It can be understood that the flexible guide 40 can flexibly adapt to the shape and structure of the valve, ensuring that the soapy water can accurately cover the key detection areas of the valve, especially those places that are difficult to directly contact or observe, which helps to improve the comprehensiveness and accuracy of leakage detection. Moreover, since the flexible guide 40 has a certain flexibility and plasticity, the flexible guide 40 can be applicable to various types of valves, increasing the versatility and flexibility of the monitoring system 1. Of course, the design of the flexible guide 40 reduces the interference that may be caused to the surrounding environment when the soapy water flows directly out of the outlet, so that the soapy water can act more concentratedly on the target area, thereby improving the detection efficiency.

[0054] It is worth mentioning that the flexible guide 40 is easy to install and adjust, and its position or direction can be quickly changed according to actual needs to adapt to different detection requirements. Moreover, the existence of the flexible guide 40 simplifies the operation process, and the user can complete the installation and adjustment work without complicated tools, thereby improving the overall user experience. At the same time, by ensuring that the soapy water can evenly and fully cover the valve surface, the flexible guide 40 helps to detect potential leakage points earlier and more accurately, thereby enhancing the reliability of the entire monitoring system 1.

[0055] According to some embodiments of the present invention, the other ends of the plurality of flexible flow guides 40 are spaced apart along the circumference of the valve.

[0056] In some embodiments, the other ends of the plurality of flexible flow guides 40 are distributed at intervals in the circumferential direction, so that the soapy water can be evenly distributed on the entire circumference of the valve, thereby achieving full coverage of the valve surface, which helps to improve the accuracy of leak detection and ensure that no possible leak points are missed. That is, because the soapy water can evenly cover all parts of the valve, even the slightest leak can be discovered in time, thereby enhancing the detection capability of the monitoring system 1 and improving the overall safety and reliability.

[0057] Of course, the circumferential distribution design of the flexible guide 40 enables the monitoring system 1 to adapt to valves of various shapes and sizes, increasing the versatility and flexibility of the monitoring system 1. That is, whether the valve is circular, elliptical or other complex shapes, effective coverage of soapy water can be ensured.

[0058] It is worth mentioning that the conventional detection method may produce detection blind spots because some areas are difficult to reach, but the above-mentioned setting can effectively reduce these blind spots, so that each part can be fully inspected, and the evenly distributed flexible guides 40 ensure that the soapy water is reasonably distributed to each location that needs to be inspected, avoiding waste caused by local excessive spraying, while also ensuring detection efficiency. At the same time, when the soapy water evenly covers the valve, it is easier to form obvious bubbles in the event of a leak, which is convenient for users to observe and judge.

[0059] Embodiment five:

[0060] In this embodiment, on the basis of the second embodiment, the monitoring system 1 further includes: a water replenishing device, a liquid replenishing device and a concentration detection device, wherein the water replenishing device is connected to the shell 11, and is suitable for adding water into the accommodating chamber, the liquid replenishing device is connected to the shell 11, and is suitable for adding soap liquid into the accommodating chamber, and the concentration detection device is arranged on the shell 11 and is communicatively connected with the water replenishing device and the liquid replenishing device, and the concentration detection device is suitable for detecting the concentration of soap water in the accommodating chamber; wherein when the concentration detection device detects that the concentration of soap water is lower than a threshold value, the liquid replenishing device is controlled to add soap liquid into the accommodating chamber, and when the concentration detection device detects that the concentration of soap water is higher than a threshold value, the water replenishing device is controlled to add water into the accommodating chamber.

[0061] In some embodiments, the concentration detection device continuously monitors the concentration of soap water in the receiving chamber. When it is detected that the concentration of soap water is lower than a set minimum threshold value, the concentration detection device triggers the liquid replenishment device to control the liquid replenishment device to add an appropriate amount of soap liquid into the receiving chamber to increase the concentration of the soap water to an appropriate level. On the contrary, if the concentration detection device finds that the concentration of soap water is too high (i.e., exceeds the set maximum threshold value), it activates the water replenishment device to control the water replenishment device to add water into the receiving chamber to dilute the soap water, so that the concentration of soap water returns to a normal range. The entire process does not require human intervention, and the concentration detection device automatically controls the action of the water replenishment and liquid replenishment devices based on real-time data to ensure that the concentration of soap water is always maintained within an ideal range.

[0062] Therefore, by precisely controlling the concentration of soapy water, it is possible to ensure that the detection process is always carried out in the most effective state, thereby improving the accuracy and reliability of leak detection. Moreover, the automated concentration management system reduces the need for regular manual inspections and adjustments, saving time and labor costs. Of course, water or soapy liquid is added only when needed, avoiding unnecessary consumption and improving resource utilization. At the same time, stable working conditions help prevent misjudgments or missed detections due to improper soapy water concentration, further improving the safety performance of the monitoring system 1. In addition, the automated adjustment mechanism is particularly suitable for long-term continuous working environments, and can ensure that the monitoring system 1 remains in good working condition throughout the entire operating cycle.

[0063] It is worth mentioning that the concentration range of the soap water in the present application is 1%-5%, and the pH range of the soap water is 6.5-7.5, thereby preventing the soap water from corroding the natural gas pipeline or valve.

[0064] According to some embodiments of the present invention, the monitoring system 1 further includes: a detection device and an alarm device, wherein the detection device is suitable for detecting the image of the valve, and the alarm device is communicatively connected with the detection device; wherein when the detection device detects that bubbles are formed in the valve area, the alarm device is controlled to sound an alarm.

[0065] It is understandable that the detection device continuously collects and analyzes images of the valve area. Through image processing algorithms, the detection device can identify bubbles generated by gas leakage (the detection is based on the characteristics of bubbles formed by soapy water at the leakage point). Once the detection device confirms that bubbles are formed, the detection device will immediately send a signal to the alarm device. After receiving the signal, the alarm device will quickly start and sound an alarm to alert the user to potential leakage problems.

[0066] Therefore, the image detection and automatic alarm functions can instantly detect and report leakage incidents, greatly shortening the time interval from the occurrence of leakage to the taking of measures, and improving the emergency response speed. Moreover, timely alarms help prevent small-scale leaks from turning into more serious accidents and protect the safety of facilities and personnel. Of course, the use of image processing technology can more accurately identify bubbles, reduce the false alarm rate caused by environmental factors or other interference, and enhance the reliability of the monitoring system 1.

[0067] Preferably, the detection device has a network connection function to allow the user to monitor the valve status in real time at a remote location and receive alarm information, which increases flexibility. Moreover, the image detection device can also be used to record and save historical data, which is convenient for subsequent analysis and troubleshooting, and also provides a basis for optimizing maintenance plans.

[0068] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
