Description

Technical Field

[0001] This utility model relates to the field of dosing tube technology, and in particular to a quick-connect interface for a dosing tube with a sealing ring. Background Technology

[0002] A dosing line is a pipe used to deliver chemical agents or additives to various liquid systems. It is widely used in water treatment, chemical, pharmaceutical and food processing industries. A dosing line interface is a connection device, usually used to deliver agents to the required liquid through a dosing pipeline system.

[0003] Existing dosing pipe interfaces mostly use bolts and connecting sleeves to fix the interface to the dosing pipe during use. During installation, the interface needs to be aligned with the dosing pipe, and the dosing pipe and interface need to be connected and fixed in sequence through multiple threaded rods. The operation is cumbersome and the installation time is long. In view of this, this solution proposes a quick-install interface for dosing pipes with a sealing ring to solve the above problems.
