On-line leak detection device for drainage system pipeline

Abstract

The invention discloses an on-line leak detection device for a drainage system pipeline. The on-line leak detection device comprises a leak detection device body, wherein the leak detection device body comprises a four-way valve, an air tube, a pressure gage, a pressurizing air bag and a sealed air bag, wherein the two ends of the air tube are respectively connected with a first port of the four-way valve and the sealed air bag; an air inlet and an air outlet are respectively formed in the two ends of the pressurizing air bag; the air outlet of the pressurizing air bag is connected with a second port of the four-way valve; an air inlet one-way valve is mounted at the air inlet of the pressurizing air bag; the pressure gage is mounted at a third port of the four-way valve; an air discharge switch is mounted at a fourth port of the four-way valve. Through the adoption of the structure, the on-line leak detection device for the drainage system pipeline, provided by the invention, is simple in structure and convenient to operate, and can greatly reduce the leak detection cost and effectively improve the leak detection efficiency.

Description

technical field [0001] The invention relates to an on-line leak detection device capable of on-line detection of water leakage in drainage system pipes. Background technique [0002] Since the pipe ports of the drainage system pipes are mostly narrow, and the length of the pipes is usually long, and the connection of the drainage system pipes is also complicated, and most of them are pre-buried installations, so once the drainage system pipes leak, people often need professional help. It is not only costly but also inefficient for leak detection personnel to search for leaks. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an online leak detection device for drainage system pipelines with simple structure and convenient operation, which can greatly reduce the cost of leak detection and effectively improve the efficiency of leak detection. [0004] In order to achieve the above purpose, the present invention pr...
