AI Technical Summary

Technical Problem

Conventional pipeline online sampling has the risk of high-temperature scalding, the asymmetric butt thread of the sampling bottle is prone to leakage, and lacks protection function to isolate the air.

Method used

A water-cooled protective connection device for pipeline sampling is designed, including a sampling bottle and a connector. The connector consists of an inner seat, an outer seat, a sampling tube and a sealing cap. It adopts a threaded connection method. The inner cavity between the inner seat and the outer seat is hollow. The outer seat can be connected to an external circulation device to provide insulation and cooling function. The air pipe can be connected to an inert gas or used for pre-vacuum.

Benefits of technology

It realizes a fast and easy disassembly and assembly import and export design, reduces leakage risk, and isolates high temperatures to prevent expansion and fragmentation of the tetrafluoroethylene inner seat. The hollow interlayer of the inner cavity provides insulation and cooling function, and the air pipe function enhances the protection of the bottle body.
