Description

Technical Field

[0001] The present application relates to the technical field of natural gas valves, and specifically to a new type of natural gas station valve structure. Background Art

[0002] A gas station valve is a device used in the production, processing, transmission and distribution of natural gas. Its main function is to control or regulate the flow of natural gas through the pipeline. In natural gas stations, valves are a vital component because they provide a means to start or stop flow, adjust flow rate, prevent backflow, regulate or release pressure, etc.

[0003] China Patent Authorization Announcement No.: CN220248954U discloses a new type of natural gas station valve structure. This solution achieves the goal of symmetrically arranging butterfly valves inside the connecting pipe, which is convenient for double sealing of the connecting pipe and improves the overall sealing performance. At the same time, a driving device is arranged on the surface of the connecting pipe to install a driving sprocket, and a driven sprocket is arranged on the surface of the butterfly valve. The driving sprocket and the driven sprocket are connected by a chain, which is convenient for the staff to quickly drive and control the two butterfly valves to open and close at the same time, thereby improving the overall sealing performance, facilitating the staff to operate, and improving the work efficiency.

[0004] However, a large amount of impurities will adhere to the natural gas station valves after use. Over time, these impurities may accumulate on the valves, affecting the sealing performance and operating efficiency of the valves. In order to avoid valve leakage, the valves need to be inspected or maintained regularly. At this time, the valves need to be disassembled, and the pipeline gas supply needs to be shut down before that. However, the disassembly and inspection of the valves takes a certain amount of time, resulting in a long interruption in the natural gas supply. This supply interruption causes trouble for downstream users who rely on continuous natural gas supply.

[0005] Therefore, it is necessary to provide a new type of natural gas station valve structure to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] like Figure 1-4 As shown, the present application provides a novel natural gas station valve structure, which is arranged between a natural gas pipeline 1 and a natural gas pipeline 2, a valve mechanism 3 is arranged between the natural gas pipeline 1 and the natural gas pipeline 2, and the natural gas pipeline 1 and the natural gas pipeline 2 are coaxially arranged;

[0028] The valve mechanism 3 includes two fixed disks 32 and a support frame 31. The support frame 31 is fixedly connected to the bottom of the two fixed disks 32. The two fixed disks 32 are respectively fixedly connected to the natural gas pipeline 1 and the natural gas pipeline 2 and are connected to each other. A connecting component 33 is arranged between the two fixed disks 32. The outer end of one of the fixed disks 32 is fixedly connected to a motor 34. The connecting component 33 includes two rotating disks 331. A connecting pipe 333 and a butterfly valve 334 are respectively installed between the two rotating disks 331. The output end of the motor 34 is key-connected to one of the rotating disks 331.

[0029] The motor 34 is configured to drive the connecting component 33 to rotate, so that the butterfly valve 334 and the connecting pipe 333 are alternately arranged coaxially with the natural gas pipeline 1 and the natural gas pipeline 2.

[0030] This solution refers to a device used in the process of natural gas production, processing, transmission and distribution, which is mainly used to control or regulate the flow of natural gas flowing through the pipeline. In addition, by rotating the connecting component 33 at an angle of 180°, the butterfly valve 334 can be repaired without interrupting the flow of natural gas. This design allows the position of the butterfly valve 334 and the connecting pipe 333 to be swapped, so that the butterfly valve 334 originally connected to the natural gas pipeline 1 and the natural gas pipeline 2 can be temporarily disconnected, and the connecting pipe 333 can take its place to maintain the supply of natural gas. This design avoids the interruption of the natural gas supply during maintenance and reduces the inconvenience and economic losses that may be caused to downstream users due to the interruption of the natural gas supply.

[0031] Specifically, during use of the valve, the butterfly valve 334 is coaxially arranged with the natural gas pipeline 1 and the natural gas pipeline 2, and the butterfly valve 334 is used to control and regulate the flow of natural gas.

[0032] Among them, when a large amount of impurities adhere to the butterfly valve 334 and affect the sealing performance of the valve and it needs to be disassembled and repaired, the motor 34 can be used to control the connecting component 33 to rotate 180°, so that the position of the butterfly valve 334 and the connecting pipe 333 are swapped. At this time, the butterfly valve 334 can be disassembled and repaired. During this process, the natural gas in the natural gas pipeline 1 can flow to the natural gas pipeline 2 2 through the connecting pipe 333, thereby ensuring the continued transportation of natural gas.

[0033] In addition, when the positions of the butterfly valve 334 and the connecting pipe 333 are exchanged, the connecting block 332 can block the natural gas to prevent leakage of the natural gas.

[0034] It should be noted that the butterfly valve 334 and the connecting pipe 333 are installed between the two rotating disks 331 by means of bolts.

[0035] like Figure 2 As shown, the ends of the two rotating disks 331 that are away from each other are integrally formed with a connecting block 332, and the sides of the two fixed disks 32 that are close to each other are provided with a receiving groove that is compatible with the connecting block 332, and the connecting block 332 is rotatably connected to the receiving groove.

[0036] In this embodiment, a slider is installed on the outer wall of the connecting block 332, and a slide groove is opened on the inner wall of the accommodating groove. The slider is slidably connected with the slide groove, thereby ensuring that the motor 34 can drive the connecting component 33 to rotate stably.

[0037] like Figure 3 As shown, two communication holes are provided inside the rotating disk 331 and the connecting block 332 , and the communication pipe 333 and the butterfly valve 334 are respectively connected to the two communication holes.

[0038] In this embodiment, when the butterfly valve 334 is coaxially arranged with the natural gas pipeline 1 and the natural gas pipeline 2, the natural gas pipeline 1, the butterfly valve 334 and the natural gas pipeline 2 are interconnected, thereby ensuring the smooth transportation of natural gas. When the connecting pipe 333 is coaxially arranged with the natural gas pipeline 1 and the natural gas pipeline 2, the natural gas pipeline 1, the connecting pipe 333 and the natural gas pipeline 2 are interconnected, thereby ensuring the smooth transportation of natural gas during the maintenance of the butterfly valve 334.

[0039] like Figure 3 As shown, two second sealing gaskets 336 are fixedly connected to one end of the connecting block 332 and located at the openings of the two communicating holes. The two second sealing gaskets 336 are both in contact with the inner wall of the receiving groove on one side of the fixed plate 32 .

[0040] In this embodiment, the sealing gasket 2 336 can play a sealing role to ensure that when 334 is coaxially arranged with the natural gas pipeline 1 and the natural gas pipeline 2 or the connecting pipe 333 is coaxially arranged with the natural gas pipeline 1 and the natural gas pipeline 2, the natural gas will not leak from the connecting hole.

[0041] like Figure 3 As shown, a plurality of sealing rings 337 are installed on the outer wall of the connecting block 332 , and the sealing rings 337 abut against the inner wall of the receiving groove on one side of the fixing plate 32 .

[0042] In this embodiment, the sealing ring 337 is provided to abut against the inner side wall of the receiving groove on one side of the fixed disk 32 to ensure the sealing between the connecting block 332 and the fixed disk 32 during the rotation of the connecting component 33 .

[0043] like Figure 1-3 As shown, a sealing gasket 335 is fixedly connected to one end of the rotating disk 331 close to the connecting block 332 , and the sealing gasket 335 abuts against the fixed disk 32 .

[0044] In this embodiment, by installing a sealing gasket 335 on one side of the rotating disk 331, the sealing between the rotating disk 331 and the fixed disk 32 can be further ensured.

[0045] Working principle: When a large amount of impurities adhere to the butterfly valve 334 and affect the sealing performance of the valve, it needs to be disassembled and repaired, the motor 34 can be used to control the connecting component 33 to rotate 180°, so that the position of the butterfly valve 334 and the connecting pipe 333 are swapped. At this time, the butterfly valve 334 can be disassembled and repaired. During this process, the natural gas in the natural gas pipeline 1 can flow to the natural gas pipeline 2 2 through the connecting pipe 333, thereby ensuring the continued transportation of natural gas. When the butterfly valve 334 is repaired and installed, the motor 34 is used to control the connecting component 33 to rotate 180°, so that the butterfly valve 334 continues to work.

[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
