Abstract

The invention discloses a metering detection device for gas leakage volume detection, and particularly relates to the technical field of gas leakage detection.The metering detection device comprises a first sleeve and a second sleeve which are installed at the outer end of a pipeline, and the tops of the first sleeve and the second sleeve are in threaded connection with the same connecting lantern ring; the first sleeve and the second sleeve are filled with inert gas, plugging mechanisms are arranged in the first sleeve and the second sleeve, an inflation pipe is fixedly arranged on one side of the top of the second sleeve, the bottom end of the inflation pipe extends into the second sleeve, and the inflation pipe is connected with the interior of the second sleeve. An electromagnetic valve is fixedly arranged at the outer end of the inflation pipe and arranged at the top of the second sleeve, and a transparent cylinder is arranged on one side of the inflation pipe. The transparent cylinder and the rubber piston are installed at the top end of the second sleeve, air leakage detection is conducted through the control mechanism, the control mechanism is used for starting the plugging mechanism to plug the air leakage position, and therefore potential safety hazards can be avoided.

Description

technical field

[0001] The invention relates to the technical field of gas leakage detection, in particular to a measuring and detecting device for gas leakage volume detection. Background technique

[0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. When transporting over a long distance, multiple pipes need to be connected, and the joints of the pipes are often connected with flanges. After the pipeline is used for a long time, the joint...
