Self reflecting protective device for firefighting pipeline

Abstract

The invention provides a self reflecting protective device for a pipeline. The self reflecting protective device comprises a stop valve, an electric actuating mechanism, a pressure sensor group, an uninterruptible power supply module and a microcontroller control module; the stop valve is connected with the electric actuating mechanism; the pressure sensor group is arranged between the stop valve and the microcontroller control module; a relay of the microcontroller control module is connected with a control circuit of the electric actuating mechanism; and the uninterruptible power supply module is connected with the stop valve, the electric actuating mechanism, the pressure sensor group, and the microcontroller control module and supplies electricity to the stop valve, the electric actuating mechanism, the pressure sensor group, and the microcontroller control module. According to the self reflecting protective device, on the basis that the stop valve is controlled by the electric actuating mechanism, the pressure sensor group and the microcontroller control module are arranged, thus, the stop valve can serve as an actuating mechanism, meanwhile detect the change of pressure in front of and behind the valve and conduct analytical judgment, the device has a independent decision-making function, within seconds when a pipe network is damaged, detecting, judging, decision making and valve stopping can be completed, and the self protecting and alarming functions of the pipe network are achieved.

Description

technical field [0001] The invention relates to a self-reflective protective device for pipelines, in particular to a self-reflective protective device for fire-fighting pipelines. Background technique [0002] The fire-fighting pipeline generally adopts a planar circular main pipe, a vertical straight main pipe, a horizontal connecting pipe and an appropriately arranged shut-off valve to ensure the survivability of the pipeline, so as to realize the supply of fire-fighting water in the case of partial damage to the pipeline, among which The function of the shut-off valve is to isolate the damaged part when there is a significant leakage in the pipeline, so as to avoid the loss of fire water without interrupting the water supply of the fire branch pipe. [0003] At present, the fault diagnosis of the fire-fighting pipe network mainly depends on empirical judgment and manual search, and then the manual cut-off valve is used to shut off the faulty part of the pipe network to i...

Problems solved by technology

[0003] At present, the fault diagnosis of the fire-fighting pipe network mainly depends on empirical judgment and manual search, and then the manual cut-off valve is used to shut off the faulty part of the pipe network to isolate the faulty pipe so that the fire-fighting pipe can continue to run; The method of manual search, judgment and disposal takes a long time, usually more than 20 minutes, but when a disaster occurs, the difficulty of search and processing increases, and the time will be longer, especially when the disaster is severe and the pipe network is severely damaged , the power supply and communication lines are interrupted, the accuracy rate of the manual judgment and processing process will be lower, and the time-consuming will be longer, which may delay the timing of fire extinguishing by the fire protection system and severely damage the safety of life and property.
