PIPE CONNECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/072564
Kind Code:
A1
Abstract:
A pipe connection system, comprising a male pipe connector (1) and a female pipe connector (2). The female pipe connector (2) is internally provided with a stepped bore. The stepped bore divides the female pipe connector into a large diameter bore portion (21) and a small diameter bore portion (24). An end portion of the male pipe connector (1) is connected to the large diameter bore portion (21) of the female pipe connector (2) by insertion. The male pipe connector (1) and the female pipe connector (2) are threadedly connected and sealed by means of a sealing structure. The pipe connection system uses a screw thread and sealing ring (3) structure to enhance the sealing effect of a pipe component. After expanding the bore of the female pipe connector (2), an inner thread and outer thread can be engaged and reinforced using a sealing ring (3) to achieve double sealing of a connected portion. The invention requires no additional technique, shortens operating processes, and improves device quality and production efficiency.
