Pressure pipeline rapid pressure test joint and pressure pipeline rapid pressure test method

Abstract

The invention discloses a quick pressure test joint of a pressure pipeline and a pressure test method. The pressure test joint includes a fixing device that can be fixed and embraced on the pressure pipeline to be tested, and a drill pipe used for drilling holes on the pressure pipeline to be tested. ; The fixing device has an installation hole arranged through the radial direction of the pressure pipeline to be tested in cooperation with it, and the fixing device is located at the side of the installation hole facing the pressure pipeline to be tested and is provided with a seal for sealing parts; the side wall of the front end of the drill rod has a water inlet connected to the rear end, and the rear end of the drill rod has a joint for connecting the pressure test device; the front end of the drill rod can pass through The installation hole is drilled into the pressure pipeline to be tested and installed on the installation hole in a sealed manner, and the water inlet is located in the pressure pipeline to be tested. The invention has the advantages of convenient installation without disassembly, which is beneficial to simplify the pressure test work flow, reduce the waste of water resources, reduce the pressure test cost and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a quick pressure test joint of a pressure pipeline and a pressure test method. Background technique [0002] The water supply and drainage system is an indispensable and important part of modern buildings. After the installation of the water supply and drainage pipes, the functional test of the pipes should be carried out, and the pressure pipes should be subjected to the hydraulic pressure test of the pressure pipes. [0003] During the hydrostatic test of the pressure pipeline, the pressure test device is generally installed at the beginning and end of the pipeline or next to the exhaust device, and then the pipeline is injected with water for pressure test. After the pressure test is completed, the pipeline must be emptied before the pressure test device can be removed. During the above-mentioned test process, it is necessary to complete the installation and disas...

AI Technical Summary

Problems solved by technology

In the above test process, it is necessary to complete the installation and disassembly of the pressure test device, and to fill and drain the pipeline. The operation process is cumbersome, which will cause waste of water resources and make the pressure test cost higher.
