Quick-connect couplings allow workers to complete the connection in a very short time, improving work efficiency. Quick-connect couplings provide better sealing performance, ensuring the normal operation of the system, and reducing resource waste and environmental pollution caused by leakage. Later inspection and replacement of parts become more convenient. Maintenance personnel can disassemble and replace parts with simple operations, eliminating the need for complicated tools and cumbersome steps, thereby saving maintenance costs and downtime.

[0014] 2. The use of connectors that can be connected and disassembled simultaneously improves the convenience of installation and maintenance, allowing for quick connection or disassembly, saving a significant amount of time and labor costs. When equipment needs repair or component replacement, maintenance personnel can quickly complete the operation, reducing the risk of misoperation. Attached Figure Description
