Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically a leak-proof pipeline for transporting chemical materials. Background Technology

[0002] Chemical pipelines are pipeline systems and equipment used for the transport, distribution, mixing, separation, discharge, metering, and monitoring of the flow of liquids, gases, suspensions, and gases.

[0003] Reference patent (publication number: CN221237352U; publication date: 2024-06-28) discloses a drip-proof chemical material conveying pipeline, including a first connector and a second connector. A first annular plate is provided on one side of the first connector, and a plurality of first annular sealing grooves are formed on the outer surface of the first annular plate. A first annular sealing gasket is fitted in each of the plurality of first annular sealing grooves. A first annular groove is formed on one side of the second connector, and a second annular plate is provided on the side of the second connector with the first annular groove. A plurality of second annular sealing grooves are formed on the outer surface of the second annular plate.

[0004] Based on the aforementioned patents, chemical material conveying pipelines typically require splicing to increase pipeline length during use. However, the connections between pipelines are fixed with bolts, making disassembly and installation cumbersome. Furthermore, during installation, it is difficult to accurately align the first and second conveying pipe bodies, ensuring coaxiality of the pipeline connections and poor sealing performance at the pipe connections. Most existing pipelines rely solely on a single sealing structure, which is insufficient to effectively prevent material leakage when faced with the complex chemical properties of chemical materials, varying conveying pressures, and temperature changes. Therefore, this utility model provides a leak-proof chemical material conveying pipeline. Utility Model Content

Furthermore, during installation, it is difficult to accurately align the first and second conveying pipe bodies, making it difficult to ensure the coaxiality of the pipeline connection, and the sealing performance at the pipeline connection is poor. Most existing pipelines rely on a single sealing structure, which is insufficient to effectively prevent material leakage when faced with the complex chemical properties of chemical materials, different conveying pressures, and temperature changes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof chemical material conveying pipeline, comprising a first conveying pipe body, wherein the first conveying pipe body is provided with an installation mechanism for the chemical material conveying pipeline, the installation mechanism comprising:

[0014] Beneficial effects

[0015] This invention provides a leak-proof chemical material conveying pipeline. Compared with the prior art, it has the following advantages:

[0016] Firstly, when the first conveying pipe body and the second conveying pipe body are connected in a close fit, the positioning rod on the second conveying pipe body is positioned and engaged with the positioning groove plate on the first connecting plate. This ensures that the first and second conveying pipe bodies are accurately aligned during connection, guaranteeing the coaxiality of the pipe connection and preventing misalignment that could affect material conveying. At the same time, the main rubber ring, the outer rubber ring, and the inner rubber ring are tightly fitted with the sealing groove, forming a multi-layer sealing structure. This effectively prevents chemical materials from leaking from the pipe connection, improving the pipe's sealing performance and safety. Furthermore, the rubber rings have a certain degree of elasticity, which can act as a buffer and shock absorber at the pipe connection.

[0017] Secondly, this utility model fits the first connecting plate and the second connecting plate together, and at the same time, the locking bracket on the slider engages with the engaging groove on the first connecting plate. Rotating the screw causes the slip ring to slide along the outer wall of the slide rod and the main body of the second conveying pipe, so that the slip ring moves away from the second connecting plate. The locking groove on the inner side of the locking bracket engages with the locking rod on the inner wall of the engaging groove, thereby realizing the locking connection of the two sets of pipes. The operation process is simple and quick, without the need for complicated tools and cumbersome steps, which helps to improve the efficiency of pipe installation and maintenance.

[0018] Thirdly, the outermost alloy steel layer of the conveying pipeline of this utility model has high strength and good wear resistance, which can withstand external mechanical impact, friction and a certain pressure, protect the internal structure of the pipeline from damage, and improve the overall pressure resistance and deformation resistance of the pipeline. The middle rubber layer has good elasticity and flexibility, which can buffer the vibration and noise generated by the pipeline during material transportation, reduce the impact of pipeline vibration caused by material flow on the surrounding environment, and absorb a certain impact force, protecting the alloy steel layer and stainless steel layer from excessive stress, and extending the service life of the pipeline. The inner stainless steel layer has excellent corrosion resistance, can resist the erosion of chemical materials, prevent the inner wall of the pipeline from being corroded and affecting the quality of material transportation, and avoid safety hazards such as pipeline leakage caused by corrosion. In addition, the rubber layer has low thermal conductivity and has a certain heat insulation performance, which can reduce the heat exchange between the material inside the pipeline and the external environment. For the transportation of chemical materials with temperature requirements, it helps to maintain the temperature stability of the material, thereby improving the overall effect of the conveying pipeline.
