Pipe network blocking detecting device

Abstract

The invention belongs to the technical field of detection and provides a pipe network blocking detecting device. The pipe network blocking detecting device is characterized in that as an external detecting device used for the pipeline blocking, the detecting device has functions of blocking fault alarming and blocking fault point positioning. A clamping device of a sensor is convenient to detach and mount and composed of an upper clamping handle, a rotary shaft, an upper cable, an upper soft rubber gasket, an upper arc iron plate, a lower clamping handle, a lower soft rubber gasket, a low arc iron plate, a lower cable and a releasable fastener. The pipe network blocking detecting device has the advantages that the clamping device is simple and durable, common running of the pipe network is unaffected during detection of the device, and detection runs smoothly without influence from complicated pipe network. The pipe network blocking detecting device is suitable to blocking identifying and positioning of the industrial feed piping, the urban feed piping and the like and is rapid to respond the fault, easy to mount and operate, high in detecting accuracy and like.

Description

technical field [0001] The invention relates to a pipe network clogging detection device, which belongs to the technical field of detection, and specifically relates to a detection technology for realizing pipe network clogging recognition through the difference in capacitance readings measured when the pipe network works normally and when it is blocked, and is suitable for industrial water supply pipelines and urban The blockage identification and location of water supply pipelines have the advantages of low detection cost, fast fault response, high detection accuracy and convenient installation and operation. Background technique [0002] The problem of pipeline blockage is one of the common pipeline faults. Water supply pipelines are mainly used in water supply enterprises and civil industries. At present, the blockage detection methods of such pipelines are mostly the area meter method and the manual percussion listening method. Among them, the regional meter installatio...

Problems solved by technology

[0004] The invention is a pipe network blockage detection device, which overcomes the defects of complicated installation, low positioning accuracy and knocking and listening method, which require high experience for blocking detection personnel and low detection accuracy in the traditional area meter installation method. The easy-to-operate external detection method uses the principle that there will be air in the downstream section of the pipeline after the pipeline is blocked, and the dielectric constant of air is about 80 times different from that of water, and the difference in capacitance value is dozens of pF. The difference between the measured capacitance value and the normal state, combined with the manual point-finding method, detects the blockage point, thereby effectively improving the positioning accuracy of the blockage and reducing the detection cost
