Abstract

The invention relates to the field of gas transmission pipeline detection, in particular to a dragging type disassembly-free gas leakage detection device for a gas transmission pipeline. The dragging type disassembly-free gas leakage detection device comprises a first clamping ring, a second clamping ring, a pressure measuring assembly and the like, wherein the first clamping ring is connected with a second clamping ring through a hinge, and the pressure measuring assembly is arranged on the second clamping ring. Through cooperation of the pressure measuring assembly and a pressure reducing assembly, an air extracting pump moves up and down in a reciprocating mode to extract air in a closed space jointly formed by the first clamping ring and the second clamping ring, the air in the closed space is extracted through the air extracting pump, and therefore the external air pressure is larger than the air pressure in the closed space and is the same as the air pressure in the closed space; and at the moment, a sliding frame moves upwards to reset under the action of a first spring, the detection personnel manually turns off a servo motor, the surface of the leaked gas pipeline is marked, and the detection personnel judges whether the gas pipeline leaks gas or not by observing the up-and-down movement state of the sliding frame.

Description

technical field [0001] The invention relates to the field of detection of gas transmission pipelines, in particular to a drag-type non-disassembly gas leakage detection device for gas transmission pipelines. Background technique [0002] Gas pipelines refer to pipelines mainly used to transport natural gas, liquefied petroleum gas, and artificial gas. In long-distance transportation, gas pipelines refer to the transportation of natural gas media. In cities and towns, gas transmission pipelines refer to the transportation of natural gas, liquefied petroleum gas, artificial gas and other media. The operation of checking the leakage of gas pipeline is one of the important tasks of daily maintenance and management of gas transmission and distribution system. [0003] In the prior art, direct observation is usually used to determine when checking for leaks. Hands, eyes, nose, and ears should cooperate and coordinate actions to see whether there are soap bubbles in the interface ...
