Description

Technical Field

[0001] The utility model belongs to the technical field of connecting pipes, and particularly relates to a connecting pipe for a packaging barrel cover for preventing unorganized emission of VOCs. Background Art

[0002] The packaging barrel cover, as a key component for container sealing and safety, plays an indispensable role. It is made of high-strength and corrosion-resistant materials, such as high-quality plastics or metal alloys, to ensure firm sealing in various environments and prevent the leakage of the contents or external contamination. In terms of design, the barrel cover usually adopts a threaded locking mechanism or a snap-type sealing structure, which is convenient for users to open and close easily while ensuring the sealing effect.

[0003] Currently, when pumping materials from the ton barrel packaging barrel cover on the market, it is usually necessary to remove the barrel cover and then directly insert the suction pipe into the open barrel mouth for suction. In this way, the volatility of the liquid inside the barrel often causes unorganized emission of VOCs. And during the suction process, the traditional suction pipe has no filtering structure, and the environment of the liquid inside the barrel is complex. If lumpy precipitates enter the pipe body during the suction process, it is very easy to cause blockage of the pipeline, thereby damaging the equipment. Summary of the Utility Model
