Description

Technical Field

[0001] This utility model relates to the field of pipe flange technology, and more specifically to a marine pipe flange with a sealing structure. Background Technology

[0002] There are many pipe structures distributed inside ships, which transport gases or liquids to ensure that the people on board can live and regulate their lives normally. Because ships travel on seas with large waves, the swaying caused by the movement can have a serious negative impact on the pipes. Flanges are parts that connect shafts to shafts and are used to connect pipe ends. Flanges are also used on equipment inlets and outlets. When used on equipment, it refers to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges. Gaskets are used to seal between the flanges.

[0003] Inadequacies of existing technology: Existing flange connections lack dustproof devices, allowing dust to enter the flange connections and making it easy for gaps to appear at the sealing sleeve connections, leading to the risk of leakage at the flange connections; Existing ship pipeline connections require considerable stability and sealing due to the swaying of the hull, and current pipelines are connected to each other using bolts through flanges, so there is a possibility of water leakage when the ship is swaying.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by incorporating a sealing mechanism, helps to cope with these external changes, maintain the pipeline's airtightness, prevent accidental leaks, and ensure system safety. The well-sealed flange joint reduces the need for frequent maintenance and component replacement due to leaks, avoiding equipment damage, corrosion, and pollution caused by liquid and gas leaks, thereby reducing ship downtime and maintenance costs. The sealing mechanism can select appropriate materials and designs according to different working conditions, ensuring the pipeline maintains good airtightness under various conditions and preventing leaks or malfunctions caused by changes in the external environment. Pipeline leaks may lead to harmful substances such as oil and chemicals flowing into the ocean, causing serious environmental pollution. The sealing mechanism can effectively prevent this from happening, protecting the marine ecological environment and meeting environmental protection standards.

[0014] 2. This utility model, by incorporating a pressurizing mechanism, helps maintain tight contact between the sealing surfaces under high temperature, high pressure, or vibration environments, effectively preventing leakage. The medium in ship pipelines is often affected by temperature changes; when the temperature rises, the pipeline material may expand or contract, leading to a larger gap between the sealing surfaces. The pressurizing mechanism can automatically compensate for the expansion or contraction caused by temperature, maintaining sufficient sealing pressure and ensuring that the sealing performance is not affected by temperature fluctuations. Over time, the seals will gradually wear due to friction and compression, and the sealing performance will decrease. The pressurizing mechanism can automatically compensate for the wear of the seals, ensuring that sufficient sealing pressure is maintained even when the seals age or are damaged, preventing leakage.
