Description

Gas sampling rod

Technical Field

The utility model relates to the technical field of gas sampling equipment, in particular to a gas sampling rod.

Environmental problems have been concerned, and in particular, the quality of air is directly related to the life and health of people. With the high development of cities, industries such as chemical industry, decoration, construction and the like influence the air quality of living environments to a greater or lesser extent, so that the air quality of the environments needs to be detected; for the collection of on-site air samples, a sampling ball is generally used, and air is sucked into a ball body by repeatedly squeezing the sampling ball by a hand-held person so as to be brought back to a laboratory for detection and analysis, and compared with on-site detection, the process is easy to influence a detection result, and as the requirements of people on gas detection are higher and higher, the measurement technology and equipment are more and more valued. The sampling of the gas to be detected is an important link for gas detection.

Most existing gas detectors are designed for pure gaseous materials, such as storage tank headspace gas, pipeline gas, downhole channel gas, etc., without requiring a dedicated gas sampling rod, or with a simple hollow rod gas sampling rod. The front of the hollow rod is provided with a small hole for preventing substances except gas from entering the rod, but when detecting the gas in a solid-phase gap, some solid density and viscosity are larger, the sampling rod needs to overcome great resistance to enable the existing gas sampling rod to be inserted into a solid-phase object, in the process, the solid-phase object blocks the small hole at the front end of the sampling rod of the gas detector, so that air suction is difficult, a gas sample cannot be collected, and even some impurity particles are pumped into the sampler, so that the normal work of the sampler is influenced. This has just caused that every measurement all need dredge the clearance to the gas sampling pole, is showing restriction work efficiency, has also influenced the accuracy of testing result.

Thus, in view of the above problems, we propose a gas sampling rod.
