Gas quantitative analysis device and method

Abstract

The invention belongs to the technical field of gas analysis equipment, and particularly relates to a gas quantitative analysis device, which comprises a main body. A gas conveying pipe is arranged at the rear end of the main body, a fixing ring sleeve used for sealing the gas conveying pipe is fixedly connected to the outer side of the front end of the gas conveying pipe, and a storage box used for storing standard gas is slidably connected to one side of the main body; a clamping seat used for fixing a standard gas test tube is fixedly connected to the interior of the storage box, and a winding shaft used for storing the gas conveying pipe is fixedly connected to the rear end of the main body. A pulling plate is pulled towards the right end to drive a movable ring to move to the right end of the fixing ring sleeve to compress the fixing ring sleeve made of rubber, so that the fixing ring sleeve clamps and seals the gas conveying pipe, and the gas conveying pipe is prevented from loosening after being used for a long time; the gas conveying pipe is rotationally stored around a winding shaft, an elastic rope is pulled out, a hanging plate is hung at one end of a hook plate, the gas conveying pipe is pressed and fixed to prevent the gas conveying pipe from being scattered and affecting carrying, operation is easy, and taking and using are convenient.

Description

technical field [0001] The invention belongs to the technical field of gas analysis equipment, and in particular relates to a gas quantitative analysis device and method. Background technique [0002] A gas sensor is a device that converts information about the type of gas and its concentration into electrical signals. According to the strength of these electrical signals, information related to the existence of the gas to be measured in the environment can be obtained, so that detection, monitoring, and alarm can be carried out. In the food industry, chemical industry, environmental monitoring, medical diagnosis, safety inspection and other fields, the intelligent odor recognition instrument composed of gas sensor and pattern recognition system has a wide range of applications, and has attracted more and more attention. More and more gas analysis Devices appear on the market, which contain a gas quantitative analysis device. [0003] The original gas analysis device requi...

AI Technical Summary

Problems solved by technology

[0003] The original gas analysis device requires a high airtightness of the gas delivery pipe during use, but most of the original devices are directly inserted into use, and the nozzle is easy to loosen and leak after long-term use, and due to the long gas delivery pipe , it is not easy to store or carry after use, and it is often necessary to carry standard gas during detection work, but the original device cannot store it, and it is easy to lose it in other places, and the residual gas cannot be stored after the analysis is over , random discharge will have an impact on the environment
