Abstract

The invention discloses a pressure conduit plugging device, which is characterized by comprising a beam, wherein the beam is vertically screwed with a screw, a hydraulic oil cylinder is arranged in the screw, and the upper part of the screw is provided with an interface which is inserted into an oil cavity and is used for connecting a pressure oil pump; a piston of the oil cylinder is arranged atthe lower end in the screw and is connected with a pressure block which is used for compacting fluid sealant; and two ends of the beam are provided with flexible locking components which fix the device on the pipeline. The pressure conduit plugging device solves the technical problems of the conventional plugging device that spare parts are excessive, the structure is complicated, the replacementis troublesome, the plugging cannot be carried out quickly and the plugging pressure is small. The pressure conduit plugging device is applicable to emergency rescue when pressure conducts leak, and the pressure conducts are used for delivering flammable and explosive chemicals in the industries such as electric power, chemical industry, petroleum, metallurgy, fire-fighting and the like.

Description

technical field [0001] The present invention relates to a leak-stopping device for a pipeline, in particular to a leak-stopping device used for emergency rescue when a pressure pipeline for conveying flammable and explosive chemicals leaks. Background technique [0002] Hazardous chemicals are flammable, explosive, toxic, corrosive, and harmful gases or liquids. The pressure pipelines for transporting hazardous chemicals are sometimes caused by poor quality of processing and damage during long-term work, as well as corrosion, The effect of high and low temperature, or due to factors such as vibration and collision, cracks, cracks or loss of sealing can lead to leakage of dangerous chemicals. If the leakage is not blocked in time, the consequences will be disastrous. At present, the plugging method commonly used by people is mainly a plugging gun, which is used to inject glue into the leakage joint and fix it by external force. This kind of plugging gun cannot effectively and...
