Description

Technical Field

[0001] This application relates to the field of gas transmission and distribution equipment technology, and more specifically, to a modular gas transmission and distribution pressure regulating component with a multi-parallel and hierarchical structure. Background Technology

[0002] Traditional gas transmission and distribution pressure regulating stations generally suffer from large footprints and low integration, primarily due to their monolithic design approach. Existing pressure regulating stations typically employ a single pipeline system, with all functional components concentrated on the same plane, resulting in a loose equipment layout and low space utilization. In terms of installation and maintenance, the lack of modular design necessitates a complete shutdown during maintenance, complicating operations and impacting gas supply continuity. Furthermore, existing pressure regulating stations have poor functional expandability; adjusting gas flow or adding functional modules often requires large-scale modifications. Regarding pipeline layout, traditional designs mix various pipelines on the same spatial level, increasing installation difficulty and easily causing pipeline cross-interference, affecting system reliability. This structure also makes high-level equipment integration difficult, hindering standardized production. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0003] The purpose of this invention is to provide a modular gas transmission and distribution pressure regulating component and its pipeline connection structure that adopts a multi-path parallel and hierarchical structure, which has the advantages of improving space utilization, facilitating maintenance and repair, enhancing gas supply continuity, and realizing standardized production.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A modular gas transmission and distribution pressure regulating component with a multi-parallel and hierarchical structure includes several gas transmission and distribution pressure regulating modules arranged in parallel.

[0006] The gas transmission and distribution pressure regulating module includes a bracket, a filter at one end of the bracket, a front end of the filter for introducing gas, a first shut-off valve for controlling on / off at the rear end of the filter, a first pipeline at the rear end of the first shut-off valve, a first pressure gauge on the first pipeline, a manual pressure regulator at the rear end of the first pipeline and connected to a second pipeline, a second pressure gauge on the second pipeline, a pressure regulator at the rear end of the second pipeline and connected to a third pipeline, a third pressure gauge and a pressure transmitter on the third pipeline, the rear end of the third pipeline connected to a fourth pipeline, and a second shut-off valve for controlling on / off at the rear end of the fourth pipeline.

[0007] Furthermore, this application also proposes that the bottom of the filter is provided with a drain pipe, all drain pipes are located at the same height, and adjacent drain pipes are connected by a first connecting pipe.

[0008] Furthermore, this application also proposes that a venting pipe is provided on the fourth pipeline, all venting pipes are located at the same height, and adjacent venting pipes are connected by a second connecting pipe.

[0009] Furthermore, this application also proposes that the support, sewage pipe and vent pipe of the gas transmission and distribution pressure regulating module are located on three horizontal planes at different heights.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This invention arranges pipelines with different functions in layers, compressing the planar projection size. Meanwhile, existing pressure regulating stations lack replaceable independent unit structures, hindering rapid maintenance and expansion. Therefore, this invention proposes to decompose the overall system into standardized modular units, achieving capacity aggregation through parallel connection, and employing a vertically layered layout within each module to form a three-dimensional structure.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, the present invention proposes a modular gas transmission and distribution pressure regulating component with a multi-path parallel and hierarchical structure, comprising several gas transmission and distribution pressure regulating modules arranged in parallel;

[0017] The gas transmission and distribution pressure regulating module includes a bracket 1. A filter 2 is provided at one end of the bracket 1. The front end of the filter 2 is used to introduce gas. The rear end of the filter 2 is provided with a first shut-off valve 3 for controlling the on / off state. A first pipeline 4 is provided at the rear end of the first shut-off valve 3. A first pressure gauge 5 is provided on the first pipeline 4. A manual pressure regulator 6 is provided at the rear end of the first pipeline 4 and is connected to a second pipeline 7. A second pressure gauge 8 is provided on the second pipeline 7. A pressure regulator 9 is provided at the rear end of the second pipeline 7 and is connected to a third pipeline 10. A third pressure gauge 11 and a pressure transmitter 12 are provided on the third pipeline 10. The rear end of the third pipeline 10 is connected to a fourth pipeline 13. A second shut-off valve 14 for controlling the on / off state is provided at the rear end of the fourth pipeline 13.

[0018] The gas transmission and distribution pressure regulating module refers to an independent unit with complete gas processing functions. Specifically, it can be a steel structure frame integrating filtration, pressure regulation, and monitoring components, with each module forming an independent working unit. Support 1 refers to the supporting structure that carries the pipelines and functional components. Specifically, it can be a welded steel channel frame used to fix pipelines at different heights in layers. Filter 2 refers to the device that removes impurities from the gas. Specifically, it can be a metal mesh filter structure, installed at the gas inlet. First shut-off valve 3 refers to the actuator that controls the gas flow. Specifically, it can be an electric ball valve, installed at the outlet of filter 2. First pipeline 4 refers to the channel connecting filter 2 and the pressure regulating device. Specifically, it can be a seamless steel pipe, with the pipe diameter determined according to flow requirements. First pressure gauge 5 refers to the instrument that monitors the pressure of the filtered gas. Specifically, it can be a Bourdon tube pressure gauge, installed in the middle section of first pipeline 4. Manual pressure regulator 6 refers to the primary pressure regulating device. Specifically, it can be a lever-type pressure regulating valve, adjusting the outlet pressure via a handwheel. Second pipeline 7 refers to the channel connecting manual pressure regulator 6 and automatic pressure regulator 9. Specifically, it can be a flanged steel pipe. The second pressure gauge 8 is an instrument that monitors the pressure after primary pressure regulation; specifically, a pressure gauge with a diaphragm seal can be used. The pressure regulator 9 is a device for precise pressure control; specifically, a direct-acting pressure regulating valve can be used, automatically adjusting the opening based on downstream pressure feedback. The third pipeline 10 is the channel connecting the pressure regulator 9 to the output end; specifically, a steel pipe with an insulation layer can be used. The third pressure gauge 11 is an instrument that monitors the final output pressure; specifically, a digital display pressure gauge can be used. The pressure transmitter 12 is a device that converts pressure signals into electrical signals; specifically, a capacitive sensor can be used for remote monitoring. The fourth pipeline 13 is the channel for the final gas output; specifically, a galvanized steel pipe can be used. The second shut-off valve 14 is an actuator that controls the gas output; specifically, a pneumatic shut-off valve can be used.

[0019] Specifically, multiple gas transmission and distribution pressure regulating modules are connected in parallel to form a scalable pressure regulating system. Gas first enters the filter 2 of a single module for impurity separation, and then the first shut-off valve 3 controls its flow. As the filtered gas passes through the first pipeline 4, the pressure is monitored in real-time by the first pressure gauge 5. After initial pressure regulation by the manual pressure regulator 6, the gas enters the second pipeline 7, and the regulation effect is displayed by the second pressure gauge 8. The pressure regulator 9 makes precise adjustments based on the pressure feedback from the second pipeline 7. The processed gas enters the third pipeline 10, where dual monitoring by the third pressure gauge 11 and the pressure transmitter 12 ensures stable output pressure. Finally, when the gas is output through the fourth pipeline 13, the second shut-off valve 14 provides end-point safety. The functional components are arranged in layers on the support 1, forming a vertically stacked three-dimensional structure, reducing the space occupied in the plane.

[0020] Compared to existing technologies, traditional pressure regulating stations employ a single-path design, making it impossible to increase processing capacity by adding modules. This solution, however, achieves linear capacity expansion through parallel modules. Existing technologies suffer from dispersed monitoring instruments, leading to maintenance difficulties. This solution integrates pressure monitoring points at key nodes in the layered pipeline system, forming a visualized monitoring link. Conventional designs often involve horizontally arranged functional components occupying a large area. This solution utilizes a vertically layered layout, staggering the pipelines of different functional sections vertically, effectively reducing the footprint.

[0021] Through the above technical solutions, this application achieves three-dimensional spatial optimization of the gas transmission and distribution system, allowing for the deployment of more processing modules within the same floor area. Modular design enables independent maintenance and replacement of individual functional units, avoiding overall system downtime. The parallel structure allows for the addition or reduction of modules based on actual gas demand, enhancing system configuration flexibility. The layered pipeline system forms a clear gas processing flow, shortening fault location time during maintenance.

[0022] This application further proposes to provide a drain pipe 15 at the bottom of the filter 2, with all drain pipes 15 located at the same height and adjacent drain pipes 15 connected by a first connecting pipe 16.

[0023] The sewage discharge pipe 15 refers to the pipe installed at the bottom of the filter 2 for discharging impurities. It can be made of metal or corrosion-resistant materials, and its diameter can be adjusted according to actual flow requirements. "Same height" means that the outlet ends of multiple sewage discharge pipes 15 are at the same horizontal plane, which can be achieved through a bracket 1 or a fixing device, such as an adjustable-height mounting base. The first connecting pipe 16 refers to the horizontal pipe connecting adjacent sewage discharge pipes 15, and can be connected by flanges or threads, such as stainless steel flexible hoses or rigid PVC pipes.

[0024] Specifically, the drain pipes 15 of each module filter 2 are arranged at a uniform height to form a standardized structure, eliminating the need to adjust pipe height differences during installation and reducing construction complexity. Adjacent drain pipes 15 are connected in series via a first connecting pipe 16 to form a centralized drain network, allowing impurities to be discharged through any drain outlet, eliminating the need for individual handling during maintenance. For example, when a module needs to be drained, closing the corresponding first shut-off valve 3 allows impurities to be discharged through the drain pipe 15 of the adjacent module, avoiding the need to operate each drain outlet individually.

[0025] Compared to existing technologies, traditional pressure regulating stations have scattered and inconsistently positioned sewage pipes 15, requiring individual maintenance and resulting in low space utilization. This solution unifies the height of the sewage pipes 15 and interconnects them, making the pipe layout more compact, reducing space occupation, and simplifying the maintenance process. For example, existing technologies require individual cleaning of each sewage outlet, while this solution allows for overall sewage discharge through any outlet.

[0026] Through the above technical solution, this application solves the problems of complex maintenance and low space utilization caused by the dispersed sewage pipeline 15, realizes the standardization and centralization of pipeline layout, reduces maintenance workload and improves sewage discharge efficiency. For example, maintenance personnel only need to operate one sewage outlet to complete the sewage discharge of multiple modules, reducing operation time and labor costs.

[0027] This application further proposes that the fourth pipeline 13 is provided with a venting pipeline 17, all the venting pipelines 17 are located at the same height, and adjacent venting pipelines 17 are connected by a second connecting pipeline 18.

[0028] Among them, the venting pipeline 17 refers to the pipeline installed at the end of the gas transmission line for the safe discharge of excess gas. It can be made of stainless steel or carbon steel, and its diameter is determined according to the flow requirements. "Arranged at the same height" means that the outlets of the venting pipelines 17 of multiple modules are on a horizontal reference plane, which can be achieved by installing brackets 1 at a uniform elevation. The second connecting pipeline 18 refers to the transverse connecting pipe that connects the venting pipelines 17 of adjacent modules.

[0029] Specifically, the venting pipe 17 is uniformly arranged at the end of the fourth pipe 13, and the venting outlets of all modules are horizontally aligned to eliminate vertical space occupation. Adjacent modules are connected by the second connecting pipe 18 to form a horizontally continuous structure, enabling multiple independent discharge outlets to form a parallel network. When a module requires maintenance, its venting function can achieve emergency discharge through the connecting pipe of the adjacent module. The second connecting pipe 18 serves as a standardized interface, allowing new modules to be quickly connected to the system by docking with adjacent pipes, without the need for a separate discharge main pipe. The horizontally arranged venting pipe 17 and the fourth pipe 13 form a layered structure, avoiding spatial interference with the lower sewage pipe 15.

[0030] Compared to existing technologies, traditional pressure regulating stations typically employ a decentralized, vertically arranged venting system (17). Differences in the height of the vent outlets of different modules lead to tangled and intertwined pipelines, requiring individual inspection of vent points at different elevations during maintenance. This solution eliminates spatial conflicts through a unified horizontal arrangement. The lateral connection structure creates a planar layout for the venting system, allowing maintenance personnel to perform venting system maintenance on all modules from a single operating plane. While existing technologies require the re-laying of the main venting pipe for each new module, this solution only requires adding a second connecting pipe (18) between adjacent modules to expand the system.

[0031] Through the above technical solutions, this application achieves centralized planar management of the venting pipeline 17, reducing the problem of insufficient maintenance space caused by three-dimensional pipeline intersections. The horizontal interconnection structure between modules provides redundancy to the emission system, maintaining safe system operation in the event of a single module failure. The standardized connection method eliminates the need to modify the existing emission main pipe when expanding the pressure regulating station; new modules can be integrated directly by adding a second connecting pipeline 18. The layered design of the horizontally arranged venting pipeline 17 and the fourth pipeline 13 avoids interference with lower-level equipment, improving space utilization.

[0032] This application further proposes that the support 1, sewage pipe 15 and vent pipe 17 of the gas transmission and distribution pressure regulating module are located on three horizontal planes at different heights.

[0033] Among them, bracket 1 refers to the basic support structure that carries the gas transmission and distribution pressure regulating module, which can be implemented using a steel frame or a concrete base, and is set on the bottom plane to provide a stable installation foundation. Sewage pipe 15 refers to the piping system connected to the bottom of filter 2 for discharging impurities, which can be implemented using flanged metal pipes, and is centrally arranged on the middle plane for unified sewage discharge operation. Venting pipe 17 refers to the channel connected to the fourth pipe 13 for safe gas discharge, which can be implemented using a pressure-resistant pipe with an explosion-proof valve, and is independently set on the upper plane to avoid interference with other pipes.

[0034] Specifically, bracket 1 is fixed to the bottom plane as the installation reference for modular components. All modules' drain pipes 15 are horizontally connected in the middle plane via the first connecting pipe 16, forming a centralized drain network. The vent pipe 17 is horizontally connected in the upper plane via the second connecting pipe 18, forming an independent discharge channel. By placing the three types of functional components at different heights, a vertically layered layout is created, ensuring that the various piping systems do not interfere with each other spatially. The bottom bracket 1 provides stable support for the modules, the middle drain pipe 15 facilitates unified cleaning of impurities by maintenance personnel, and the upper vent pipe 17 ensures that the gas emission path is independent and far from the operating area. This design, by replacing the traditional planar layout with a three-dimensional layered approach, effectively reduces the equipment's footprint while creating a standardized interface layer for each functional pipe, facilitating the stacking and expansion of modules.

[0035] Compared to existing technologies, traditional gas transmission and distribution pressure regulating stations typically arrange the support structure, sewage pipe 15, and vent pipe 17 on the same plane, resulting in pipe intersections, limited maintenance access, and difficulties in expansion. This solution, however, eliminates spatial conflicts between different functional pipes through a three-dimensional layered layout, allowing each layer to have an independent operating interface, enabling layered maintenance without requiring a complete shutdown. Furthermore, the standardized layered structure allows for rapid deployment of new modules via vertical stacking, eliminating the need for replanning the floor plan.

[0036] Through the above technical solution, this application achieves vertical spatial optimization of the gas transmission and distribution pressure regulating components, reducing the risk of leakage and maintenance difficulty caused by pipeline intersections. Simultaneously, the layered standardized design allows for module expansion by simply stacking them vertically, significantly improving system deployment efficiency. Specifically, the independent setting of the bottom support 1 ensures equipment stability, the centralized arrangement of the intermediate drainage layer shortens the maintenance path, and the isolation design of the upper venting layer ensures emission safety. These three elements work together to achieve a dual improvement in space utilization and operational convenience.
