High-pressure-resistant quartz-metal pipeline sealing connector

Abstract

A high-pressure-resistant quartz-metal pipeline sealing connector comprises a quartz tube, a quartz tube connector is arranged at the tail end of the quartz tube, a convex arc face of the quartz tube connector is in sealing butt joint with a concave face of a metal tube connector through a sealing bowl, a clamping sleeve is arranged outside the quartz tube connector and the metal tube connector, and the clamping sleeve is connected with the metal tube connector through a flange. Therefore, sealing butt joint between the quartz pipe and the metal pipe is completed, and operation is carried out. The quartz pipe and the metal pipe can be perfectly sealed, the quartz pipe cannot be fractured or broken in the sealing and pressure applying process, and the sealing device has the advantages of being safe, reliable and efficient.

Description

technical field [0001] The invention relates to the technical field of multiphase fluid pipelines, in particular to a high-pressure resistant quartz-metal pipeline sealing interface. Background technique [0002] Aerospace, petrochemical, energy and environmental protection and other fields often use pipelines to transport multiphase fluids in high-pressure environments. In order to ensure the safety of fluid transportation under high pressure environment, the transportation pipeline is often made of metal or metal alloy. In order to ensure the high-precision control of the multiphase fluid transportation process, the field operators often need to know the flow state of the multiphase fluid in the pipeline in real time. and many more. The best way to obtain these states is to observe them visually. Because of this, the most commonly used method to observe the flow state of multiphase fluid in the pipeline is to open an observation window on the side of the pipeline. Howe...

Problems solved by technology

However, the quartz tube is not resistant to impact, and a small area of ​​external strong pressure will cause the quartz tube to break

After practice, people found that when installing quartz tubes to high-pressure multiphase flow pipelines, in order to ensure the sealing of the pipelines, it is necessary to compress the quartz tubes and metal or metal alloy tubes tightly. If the interface design between the quartz tubes and metal tubes is unreasonable, Quartz tubes are easily fractured and broken during sealing and pressure application
