Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm type air pressure tanks, in particular to a diaphragm type air pressure tank. Background Art

[0002] Diaphragm pressure tanks, energy storage devices consisting of a steel outer shell and a rubber diaphragm inner liner, often play a vital role in the secondary water supply systems of high-rise buildings. Because high-rise buildings require high water pressure, traditional rooftop water tanks or water towers are unable to meet these demands. Diaphragm pressure tanks, through their unique energy storage and pressure stabilization capabilities, provide stable and reliable water pressure assurance for these buildings.

[0003] After long-term use, the rubber diaphragm and other sealing materials inside existing diaphragm pressure tanks may age, harden, or crack, leading to air or water leaks. This requires regular inspection and replacement of related components, which may require disassembly and installation of the tank, increasing maintenance costs, wasting significant time and effort, and reducing work efficiency. Therefore, we propose a diaphragm pressure tank to address the aforementioned issues. Utility Model Content
