Abstract

The invention relates to the technical field of pipeline leakage detection devices, in particular to an underground pressure pipeline leakage detection device which comprises a pipeline, a reserved valve with a quick disassembly function is arranged on the pipeline, an installation sleeve is arranged on the reserved valve, and two sets of clamping grooves are symmetrically formed in the two sides of the installation sleeve. The rotating disc enables two sets of push rods to pull two sets of bearing rods to move oppositely through two sets of connecting rods and two sets of push rods, the bearing rods push bearing blocks to move along guide holes through guide columns till the bearing blocks extrude clamping blocks, and one ends of the clamping blocks move along inverted slopes arranged at the end opening portions of clamping grooves. The mounting sleeve moves downwards along the mounting hole, the movement of the mounting sleeve extrudes the sealing gasket, and meanwhile, the guide column drives the clamp to clamp the mounting sleeve, so that through the fixing mechanism, on one hand, the sealing performance of the mounting sleeve and the mounting hole is higher, the mounting sleeve is fixed, and on the other hand, the fixing mechanism is simple in structure and easy to operate; and the integrated instrument can be conveniently and quickly mounted and dismounted by workers.

Description

technical field [0001] The invention relates to the technical field of pipeline leak detection devices, in particular to an underground pressurized pipeline leak detection device and its use method. Background technique [0002] Pressurized pipelines specifically refer to deep-buried water supply pipelines, which are suitable for leak detection of water supply and fire protection pipelines, aiming to improve the screening efficiency of pipeline leakage points and reduce pipeline maintenance costs. The existing pipeline leak detection method uses a metal rod on the ground to amplify the sound wave of underground water leakage to speculate and determine the approximate area. Due to the interference of underground conditions and ground noise, it cannot be accurately located. The existing underground pressure pipeline leak detection device includes a pipeline reserve valve. And the integrated instrument, the pipeline reserved valve should be installed between the main meter and ...
