Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, specifically a uniform pressure regulating device for multi-source gas pipeline supply. Background Technology

[0002] Multi-source pipeline gas supply pressure regulation systems integrate multiple gas sources (such as natural gas gate stations, gas storage stations, and long-distance pipelines) and utilize pipeline interconnection to achieve flexibility and reliability in gas supply. Their core equipment includes pressure regulators, valves, filters, and safety shut-off valves, which stably deliver high-pressure gas to users through step-by-step pressure reduction.

[0003] The existing technology (Chinese patent publication number CN221858341U, publication date 2024-10-18) discloses a multi-source uniform gas supply and precise pressure regulation device. Its technical solution includes a main gas source point, a branch gas source point, a first gas supply pipe, a gas valve, and a second gas supply pipe. The branch gas source point and the main gas source point are connected via a delivery pipe. The first gas supply pipe and the second gas supply pipe are fixedly connected to both ends of the gas valve, respectively. The first gas supply pipe and the branch gas source point are connected via a connecting pipe. A natural gas pressure regulator is fixedly connected to the outer surface of the second gas supply pipe, and the output end of the natural gas pressure regulator is fixedly connected to a gas supply pipe. This utility model can ensure a stable gas supply to natural gas users during peak periods, stabilize the supply pressure in the gas pipeline network, ensure normal use by natural gas users, strictly control the service life of the gas pipeline network, and save costs for gas companies.

[0004] While existing technologies can stabilize the supply pressure in gas pipeline networks, they cannot provide auxiliary limiting for the valve body during installation. The valve body cannot be directly aligned with the pipeline during installation and requires debugging and calibration, resulting in low installation efficiency.

[0005] Therefore, we propose a uniform pressure regulating device for multi-source gas pipeline network supply to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a uniform pressure regulating device for multi-source gas pipeline network supply, so as to solve the problems mentioned in the background art, where it is impossible to perform auxiliary limiting on the valve body before installation, the valve body cannot be directly aligned with the pipeline during installation, and it is necessary to perform debugging and calibration, resulting in low installation efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a uniform pressure regulating device for multi-source gas pipeline network supply, including a main source pipeline, a branch source pipeline for diverting gas flow through the side of the main source pipeline, and a pressure regulating valve for adjusting the gas delivery volume between the two main source pipelines. A fixing frame is fixedly connected to the side of the pressure regulating valve, and an inner sliding plate is slidably provided on the end side of the fixing frame. A limit mechanism is provided on the outer side of the inner sliding plate. The limit mechanism achieves auxiliary limiting of the position of the pressure regulating valve by adjusting the position of the clamping plate it contains.

[0008] Furthermore, the outer side of the fixing frame extends outward along the distribution direction of the main source pipeline, and a sliding groove is provided inside the extended part of the fixing frame, and the inner sliding plate is slidably connected inside the sliding groove.

[0009] Furthermore, a connecting rod is slidably connected to the side of the fixing frame, and a pull plate is fixedly connected to the outer end of the connecting rod. A return spring is fixedly connected between the inner side of the pull plate and the outer side of the fixing frame.

[0010] Furthermore, the inner slide plate has a docking hole on the side facing the pull plate, and the docking holes are arranged in pairs at equal distances along the side of the inner slide plate in three sets. When the pull plate is not under force, the inner end of the docking rod is nested and docked into the docking hole.

[0011] Furthermore, the limiting mechanism includes a bidirectional threaded rod, which is rotatably connected to the outer end side of the inner slide plate, and two sets of clamping plates are threadedly connected to the outer side of the bidirectional threaded rod, and the clamping plates are matched with the shape of the docking part of the main source pipe and the branch source pipe.

[0012] Furthermore, a limiting rod is fixedly connected to the outer edge of the inner sliding plate, and two sets of clamping plates are slidably connected to the edge of the limiting rod.

[0013] Furthermore, the inner sliding plate and the fixed frame form a sliding structure, and the clamping plate forms a sliding structure with the limiting rod via a bidirectional threaded rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By using branch pipelines, the gas transported inside the main pipeline can be diverted, thereby improving the operating efficiency of the pipeline distribution system. At the same time, pressure regulating valves are installed on the two branch pipelines, and the gas delivery pressure can be selectively adjusted as needed, establishing a gas source scheduling mode for regional gas supply in the pipeline network to ensure the gas supply needs of users.

[0016] 2. When installing the pressure regulating valve, the operator can manually rotate the double-threaded rod. This rotation causes the clamping plates to move in opposite directions due to their threaded connection with the double-threaded rod, thus changing the distance between the two sets of clamping plates and clamping and fixing the connection between the main source pipeline and the branch source pipeline. The clamping plates on both sides provide auxiliary limiting for the pressure regulating valve, facilitating subsequent installation, improving installation efficiency, and preventing unstable connection during installation.

[0017] 3. When the upper and lower clamping plates move, they can slide along the outer side of the limiting rod set at the lower end of the inner slide plate. The limiting rod can further limit the movement of the clamping plates, thereby further ensuring the stability of the clamping plates during movement.

[0018] 4. The user can pull the pull plate outward, which will cause the pull plate to move the docking rod outward, so that the inner end of the docking rod is disengaged from the inner side of the docking hole. At this time, the user can adjust the position of the inner sliding plate according to the different pipe lengths of the installation part, so that the clamping plate is located at the upper end of the branch pipe docking part of the main source pipe, which facilitates the subsequent auxiliary installation and docking of the pressure regulating valve.

[0019] 5. After the inner slide plate position is adjusted, the pull plate can be released. At this time, the pull plate can be driven by the elastic force of the return spring to move the docking rod to the inside of the fixing frame, so that the docking rod is nested and docked into the docking hole. At this time, the docking hole and the docking rod are locked together to fix the position of the inner slide plate, so as to better position the pressure regulating valve in the future.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1: As Figure 1 The present invention provides the following technical solution: a uniform pressure regulating device for gas supply in a multi-source pipeline network, which discloses a pressure regulating valve 3. The pressure regulating valve 3 can ensure the gas supply needs of users. A branch pipeline 2 for diverting gas is provided through the side of the main source pipeline 1, and a pressure regulating valve 3 for adjusting the gas delivery volume is provided between the two main source pipelines 1.

[0029] The gas transported inside the main source pipeline 1 can be diverted through the branch source pipeline 2, thereby improving the operating efficiency of the pipeline distribution system. At the same time, pressure regulating valves 3 are installed on the two branch source pipelines 2. The gas transport pressure can be selectively adjusted as needed through the pressure regulating valves 3, establishing a gas source scheduling mode for regional gas supply in the pipeline network to ensure the gas supply needs of users.

[0030] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution shown herein provides the following technical solution: A uniform pressure regulating device for multi-source gas pipeline network supply, disclosing a limiting mechanism, which can assist in limiting the pressure regulating valve 3 to facilitate subsequent installation. A fixing frame 4 is fixedly connected to the side of the pressure regulating valve 3, and an inner sliding plate 6 is slidably provided on the end side of the fixing frame 4. A limiting mechanism is provided on the outer side of the inner sliding plate 6. The limiting mechanism achieves auxiliary limiting of the position of the pressure regulating valve 3 by adjusting the position of the clamping plate 5 included therein. The limiting mechanism includes... It includes a bidirectional threaded rod 12, which is rotatably connected to the outer end side of the inner slide plate 6. Two sets of clamping plates 5 are threadedly connected to the outer side of the bidirectional threaded rod 12. The clamping plates 5 are matched with the shape of the docking part of the main source pipe 1 and the branch source pipe 2. A limit rod 11 is fixedly connected to the outer end side of the inner slide plate 6. The two sets of clamping plates 5 are slidably connected to the side of the limit rod 11. The inner slide plate 6 and the fixing frame 4 form a sliding structure. The clamping plates 5 form a sliding structure with the limit rod 11 through the bidirectional threaded rod 12.

[0031] When installing the pressure regulating valve 3, the operator can manually rotate the bidirectional threaded rod 12. This rotation causes the clamping plates 5 to move in opposite directions due to their threaded connection with the bidirectional threaded rod 12, thus changing the distance between the two sets of clamping plates 5. As the upper and lower sets of clamping plates 5 move, they can slide along the outer side of the limiting rod 11 at the lower end of the inner slide plate 6. The limiting rod 11 further limits the movement of the clamping plates 5, ensuring stability during clamping and clamping. This also allows the clamping plates 5 to clamp and fix the connection between the main source pipe 1 and the branch source pipe 2. The clamping plates 5 on both sides provide auxiliary limiting for the pressure regulating valve 3, facilitating subsequent installation, improving installation efficiency, and preventing unstable connection during installation.

[0032] Example 3: Figure 2 , Figure 5 and Figure 6 The technical solution shown is provided by the present utility model as follows: A uniform pressure regulating device for gas supply in a multi-source pipeline network, which discloses an inner slide plate 6. The movement of the inner slide plate 6 allows the clamping plate 5 to be located at the upper end of the docking part of the branch pipeline 2 of the main source pipeline 1, which facilitates the subsequent auxiliary installation and docking of the pressure regulating valve 3. The outer side of the fixing frame 4 extends outward along the distribution direction of the main source pipeline 1, and a sliding groove 13 is provided inside the extension part of the fixing frame 4. The inner slide plate 6 is slidably connected to the inside of the sliding groove 13. A docking rod 8 is slidably connected to the side of the fixing frame 4, and a pull plate 9 is fixedly connected to the outer end of the docking rod 8. A return spring 10 is fixedly connected between the inner side of the pull plate 9 and the outer side of the fixing frame 4. A docking hole 7 is provided on the side of the inner slide plate 6 facing the pull plate 9, and three sets of docking holes 7 are arranged in pairs along the side of the inner slide plate 6 at equal distances. When the pull plate 9 is not under force, the inner end of the docking rod 8 is nested and docked into the docking hole 7.

[0033] The user can pull the pull plate 9 outward, which will cause the pull plate 9 to move the docking rod 8 outward, so that the inner end of the docking rod 8 is disengaged from the inner side of the docking hole 7. At this time, the user can adjust the position of the inner slide plate 6 according to the different pipe lengths of the installation part, so that the clamping plate 5 is located at the upper end of the docking part of the main source pipe 1 and the branch source pipe 2, which facilitates the subsequent auxiliary installation and docking of the pressure regulating valve 3. After the position of the inner slide plate 6 is adjusted, the pull plate 9 can be released. At this time, the pull plate 9 can drive the docking rod 8 to move inward to the inner side of the fixing frame 4 under the elastic force of the return spring 10, so that the docking rod 8 is nested and docked into the docking hole 7. At this time, the docking hole 7 and the docking rod 8 are locked together, fixing the position of the inner slide plate 6, so as to better position the pressure regulating valve 3 in the future.
