AI Technical Summary
Technical Problem
Existing expansion tanks are inconvenient to assemble during use, which increases the installation time and labor costs of the tank, and their cushioning performance is also poor.
Method used
The expansion tank body is made of plastic and includes a middle cylinder, an upper cover, and a lower cover. Combined with a rubber liner, an elastic sleeve, and a pulling component, the design of the sealant and sealing ring enables the tank to be quickly assembled and effectively sealed, and nitrogen is used for pressure stabilization.
Benefits of technology
It reduces production costs, improves assembly efficiency, enhances liquid buffering performance, and ensures stable system pressure.
