AI Technical Summary
Traditional hose caps have poor sealing performance and are time-consuming and laborious to disassemble, making them unsuitable for scenarios with high sealing requirements.
A double-sealed hose cover was designed, which adopts a combination structure of a supporting main cover and a snap-fit top cover. The double-sealing is achieved through components such as side snap-fit blocks, top screws and sealing chucks. The sealing effect is enhanced by the sealing chuck and outer sealing ring, and quick installation and disassembly are achieved through a simple threaded connection.
It improves the sealing effect, ensuring no leakage of materials, and is suitable for scenarios with high sealing requirements. It can also be installed and disassembled quickly, improving work efficiency and reducing equipment downtime.
