Problems solved by technology
At present, the leak detection of pipelines is carried out through pipeline gas leak detection equipment. Since the existing pipeline gas leak detection gun head is a single-tube type, it is a straight line and one-way adsorption gas for analysis and detection during high-speed leak detection on the assembly line. Insufficient detection of gas concentration in a short period of time leads to failure of leak detection, and there is a large detection blind spot, especially the back of the detection surface is easy to ignore, and cannot be detected effectively and in time

The invention discloses a gas leak detection gun head. The gas leak detection gun head comprises a butt-joint head, a main gas adsorption pipe and an auxiliary gas adsorption pipe; an included angle is formed between the axis of the main gas adsorption pipe and the axis of the auxiliary gas adsorption pipe; and therefore, the gas leak detection gun head can adsorbed gas from different directions and in different angles during a detection and sampling process, so that a detection coverage can be extended. With the gas leak detection gun head adopted, barriers brought about by a single-pipe typedetection gun head are eliminated; and multi-directional wrapping detection on a pipeline can be realized, so that detection accuracy can be improved. The invention also discloses a gas leak detection device provided with the above gas leak detection gun head.
Description
technical field [0001] The invention relates to the technical field of pipeline tightness detection, in particular to a gas leak detection device, more specifically a gas leak detection gun head. Background technique [0002] In order to ensure the quality of the product, the tightness of the pipeline of the product needs to be tested during the production process of the product. At present, the leak detection of pipelines is carried out by pipeline gas leak detection equipment. Since the existing pipeline gas leak detection gun head is a single-tube type, it is a straight line and one-way adsorption gas for analysis and detection during high-speed leak detection on the assembly line. Insufficient gas concentration in a short period of time leads to leak detection failure, and there is a large detection blind area, especially the back of the detection surface is easy to ignore, and cannot be detected effectively and in time. [0003] Therefore, how to provide a gas leak det...
