Description

Technical Field

[0001] This utility model relates to the field of pipeline transmission technology, and in particular to a pressure-stabilizing pipeline connector. Background Technology

[0002] In industrial production and daily life, the transportation of liquid or gaseous media through pipelines is a very common application scenario. To ensure the efficient and safe transport of media from one place to another, the design of the pipeline system and the selection of its components are crucial. However, in practical applications, pressure fluctuations during media transportation can lead to poor sealing at pipe joints, resulting in leaks, increased maintenance costs, and safety hazards.

[0003] Currently, Chinese utility model patent CN212868966U, published on May 11, 2020, discloses a liquid pressure reducing and stabilizing pipeline connector, comprising: a load-bearing connecting pipe, a guide cone, an elastic deformation cavity, a support frame, and a nozzle. The load-bearing connecting pipe is a hollow tubular structure with a rectangular cross-section. The guide cone, elastic deformation cavity, and support frame are all embedded within the load-bearing connecting pipe, coaxially distributed with it, and arranged from front to back along the axis of the load-bearing connecting pipe. The front end face of the guide cone is connected to the rear end face of the elastic deformation cavity through the guide pipe. Both the front and rear ends of the elastic deformation cavity are connected to the support frame. Under pressure, the elastic deformation cavity undergoes elastic deformation along the axis of the load-bearing connecting pipe, thereby regulating the pressure through the deformation of the elastic deformation cavity.

[0004] Regarding the aforementioned technologies, when using irregularly shaped components similar to the aforementioned guide cones to sense the flow velocity and pressure of the medium and apply it to the regulating component to achieve the corresponding regulating purpose, these irregularly shaped components are easily contaminated by impurities carried in the medium during long-term operation. This leads to the accumulation of impurities on the surface of the irregularly shaped component that has the "pressure sensing" effect. Over time, this will greatly reduce the "pressure sensing" effect on the surface, thereby causing the pressure regulating device to lose its regulating ability. Utility Model Content

Detailed Implementation

[0030] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] This utility model discloses a pressure stabilizing pipeline connector, as shown in the attached figure. Figure 1 -Appendix Figure 5 A pressure-stabilizing pipe connector mainly includes a pipe body 100 and a pressure-stabilizing mechanism 200. The pressure-stabilizing mechanism 200 includes a first connecting pipe 210, a pressure regulating component 220, a mounting body 240, and a first elastic element 250. The pipe body 100 includes a first pipe section 110 and a second pipe section 120. The first pipe section 110 and the second pipe section 120 are fixed and connected by the mounting body 240.

[0033] The pressure regulating assembly 220 includes a pressure cap 221, a pressure regulating diaphragm 222, and a first pressure regulating plate 223. The pressure cap 221 is fixedly connected to the mounting body 240. The fixed end of the first pipe section 110 is connected to the inlet of the pipeline through a flange, and the fixed end of the second pipe section 120 is connected to the outlet of the pipeline through a flange. The conveying medium enters the first pipe section 110 through the pipeline, and after passing through the pressure stabilizing mechanism 200, it flows back into the pipeline through the second pipe section 120. The pressure regulating diaphragm 222 is fixedly connected to both the pressure cap 221 and the mounting body 240, and a pressure regulating cavity 224 is formed between the pressure regulating diaphragm 222 and the pressure cap 221.

[0034] The first pressure regulating plate 223 is slidably disposed within the mounting body 240, and the first pressure regulating plate 223 has a pressure regulating port. The first elastic element 250 is fixedly installed within the mounting body 240; in one embodiment, see specific details. Figure 5 The first end of the first elastic element 250 is fixedly connected to the first pressure regulating plate 223 through a mounting pad, and the second end of the first elastic element 250 is connected to the mounting body 240;

[0035] One end of the first connecting pipe 210 is connected to the first pipe section 110, and the other end is connected to the pressure cap 221.

[0036] In use, the changing pressure in the pipeline is directly transmitted to the pressure regulating diaphragm 222 through the first connecting pipe 210. Then, the pressure change is sensed by the pressure regulating diaphragm 222 and the pressure regulating chamber 224, which drives the first pressure regulating plate 223 to slide. The flow area of ​​the pressure regulating port is smaller than that of the pipeline. When sliding, part of the pressure regulating port will slide into the mounting body 240. During the sliding process, the flow area of ​​the regulating port and the pipeline port is adjusted to adjust the pressure of the medium passing through the pressure regulating port, thereby achieving dynamic pressure stabilization. This reduces the possibility of impurities depositing and adhering on the pressure stabilizing mechanism 200, and also reduces the impact on the medium pressure under normal pressure conditions.

[0037] Mounting element 240 integrates pipe body 100 and pressure stabilizing mechanism 200, simplifying the structure and improving sealing. First elastic element 250 provides restoring force, ensuring return to the initial state after pressure fluctuations. Split design: Pipe body 100 is divided into two parts for easy installation and maintenance.

[0038] See attached document Figure 3 In some embodiments, the first connecting pipe 210 and the first pipe section 110 are set at a certain angle along their axial direction. The specific angle setting reference range is 30° to 45° (such as 30°, 35°, 40°, etc., which can be flexibly set according to the usage requirements). This effectively guides the fluid to smoothly change direction, significantly reduces turbulence and local pressure loss, and avoids the impact of sudden changes in flow velocity on the pressure-stabilizing diaphragm. The fluid flow direction is optimized, reducing the interference of turbulence on the pressure stabilization effect. It also reduces the possibility of impurities entering the first connecting pipe 210, reducing the possibility of blockage, and a filter screen can be added to the first connecting pipe 210.

[0039] See attached document Figure 3 and attached Figure 4In some embodiments, the pressure regulating assembly 220 further includes a second pressure regulating plate 225, which is fixedly connected to the mounting body 240. The side of the second pressure regulating plate 225 is slidably connected to the first pressure regulating plate 223. According to the needs of pipeline pressure regulation and stabilization, the second pressure regulating plate 225 has adjustment ports that correspond to the pressure regulating ports of the first pressure regulating plate 223. The staggered flow between the pressure regulating ports and adjustment ports further facilitates precise pressure stabilization and regulation. Multiple pressure regulating ports and adjustment ports can be configured according to practical needs. The second pressure regulating plate 225 provides additional guiding and limiting functions, enhancing the sliding stability of the first pressure regulating plate 223. More precise pressure regulation is achieved through the cooperation of the two pressure regulating plates.

[0040] See attached document Figure 3 and attached Figure 4 In some embodiments, the pressure regulating assembly 220 further includes a slide 226, which is fixedly connected to the first end of the first pressure regulating plate 223 and slidably connected to the mounting body 240. The first end of the first elastic member 250 is fixedly connected to the slide 226, and the second end of the first elastic member 250 is fixedly connected to the second pressure regulating plate 225. The slide 226 enlarges the contact surface, reducing the risk of uneven wear on the first pressure regulating plate 223. Force transmission optimization: the elastic member applies force evenly through the slide 226, avoiding local stress concentration.

[0041] See attached document Figure 3 and attached Figure 4 In some embodiments, the pressure regulating assembly 220 further includes a first connecting rod 227 and a second connecting rod 228. One end of the first connecting rod 227 abuts against the pressure regulating diaphragm 222, and the other end of the first connecting rod 227 is fixedly connected to the first pressure regulating plate 223. One end of the second connecting rod 228 is fixedly connected to the mounting body 240, and the other end of the second connecting rod 228 is slidably connected to the slide block 226. The second connecting rod 228 limits the stroke of the slide block 226 to prevent excessive sliding.

[0042] See attached document Figure 3 and attached Figure 4 In some embodiments, the pressure stabilizing mechanism 200 further includes a second connecting pipe 270; the mounting body 240 has a vent 232 and an adjusting cavity 290, the slide 226 slides within the adjusting cavity 290, the vent 232 communicates with the adjusting cavity 290, one end of the second connecting pipe 270 communicates with the second pipe section 120, and the other end of the second connecting pipe 270 communicates with the vent 232. Bidirectional pressure balance: The second connecting pipe 270 introduces the pressure of the second pipe section 120 into the adjusting cavity 290, achieving coordinated pressure regulation at both ends. Dynamic feedback: The vent 232 transmits pressure changes to the slide 226 in real time, improving pressure stabilization accuracy.

[0043] See attached document Figure 3 and attached Figure 4In some embodiments, the pressure stabilizing mechanism 200 further includes a second elastic element 260. The first end of the second elastic element 260 is fixedly connected to the slide 226, and the second end of the second elastic element 260 is fixedly connected to the mounting body 240. The second elastic element 260 works in conjunction with the first elastic element 250 to enhance the system's pressure resistance. Multi-level adjustment is achieved; different combinations of elastic elements with varying stiffness can adapt to a wider pressure range. The corresponding second elastic element 260 can be adjusted and replaced according to pressure stabilization needs.

[0044] See attached document Figure 3 and attached Figure 4 In some embodiments, the pressure regulating assembly 220 further includes an adjusting plate 229 and an adjusting screw 230. The adjusting plate 229 is slidably mounted on the mounting body 240 and is located within the adjusting cavity 290. One end of the adjusting screw 230 is rotatably connected to the adjusting plate 229 via a bearing, and the adjusting screw 230 is threadedly connected to the mounting body 240. By rotating the adjusting screw 230, the adjusting screw is displaced on the mounting body, thereby pulling the adjusting plate 229 connected to the adjusting screw, causing the adjusting plate 229 to move within the adjusting cavity 290. The second end of the second elastic element 260 is fixedly connected to the adjusting plate 229. By rotating the adjusting screw 230, the position of the adjusting plate 229 can be changed, and the preload of the second elastic element 260 can be adjusted to adapt to different working conditions. Users can customize the pressure stabilization threshold using the adjusting screw 230 according to actual pressure requirements.

[0045] See attached document Figure 3 and attached Figure 4 In some embodiments, the inner edge of the first pressure regulating plate 223 is formed as a flow-guiding slope 231. The slope reduces turbulence and pressure loss when the fluid passes through the pressure regulating port, improving energy efficiency. Anti-clogging: The slope design prevents the accumulation of impurities, reducing maintenance frequency.

[0046] See attached document Figure 3 and attached Figure 4 In some embodiments, the slide 226 slides against the mounting body 240 via ball bearings 280. The ball bearings 280 reduce sliding resistance and improve sensitivity. Durability: Reduces wear and extends service life.

[0047] The implementation principle of a pressure-stabilizing pipeline connector according to this utility model embodiment is as follows:

[0048] The dynamic pressure stabilization function is achieved through the coordinated design of the pressure regulating diaphragm 222, the pressure regulating chamber 224, and the first pressure regulating plate 223. It can automatically sense and adjust fluid pressure. Its compact integrated structure and split design (first pipe section 110 and second pipe section 120) ensure both sealing and ease of installation and maintenance. The system adopts a bidirectional pressure balance design, achieving coordinated pressure control at both ends through the second connecting pipe 270 and the regulating chamber 290. Simultaneously, the second elastic element 260 and the adjusting screw 230 provide manual adjustment functionality, allowing for flexible setting of the pressure stabilization threshold according to operating conditions. Furthermore, the guide slope 231 of the first pressure regulating plate 223 effectively reduces turbulence and pressure loss and lowers the risk of blockage, while the ball bearing 280 structure between the slide 226 and the mounting body 240 significantly reduces frictional resistance, improving adjustment sensitivity and extending component lifespan.

[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
