AI Technical Summary
The existing cooling water valve is integrated into the cooling system piping. In case of failure, the entire system must be shut down and the cooling water drained, which is time-consuming and costly.
The design incorporates redundant piping structures, employing connectors and manual ball valves. Flange connections enable rapid assembly and disassembly. Sub-ports and manual ball valves are installed at both ends of the pipe body to create redundant water pipe pathways, allowing for individual maintenance of faulty pipes.
It enables maintenance of faulty pipes without shutting down the system, reducing maintenance time and costs and ensuring the normal operation of the cooling system.
