Abstract

The invention relates to a device for collecting a low-pressure micro-flow gas flow signal of a pipe, and the device comprises a housing. The housing is provided with an air incoming pipe and an air outgoing pipe in a connected manner. The air incoming pipe is provided with an air spraying head. The interior of the housing is provided with a photoelectric sensor, and is also provided with a turning force providing apparatus. The turning force providing apparatus is fixedly connected with an air flow blocking plate, and the air flow blocking plate is disposed before the air spraying head. The turning force providing apparatus is also fixedly connected with a photoelectric signal reflecting plate. When the air flow blocking plate is blown to be separated from the air spraying head, the photoelectric signal reflecting plate enables the photoelectric sensor to be motivated. After the above structure is employed, the device is very high in sensitivity when the device carries out the collection of the low-pressure micro-flow signal transmitted by the pipe, is suitable for the collection detection of various types of air conveying signals, transmitted by the pipe, from middle pressure to miniature pressure and from large flow to miniature flow.

Description

technical field [0001] The invention relates to the technical field of pipeline gas detection equipment manufacturing, in particular to a collection device for pipeline micro-flow gas transmission signals. Background technique [0002] At present, pipeline gas transmission detection equipment is limited to medium and high pressure gas transmission detection. Existing instruments and equipment for low-pressure, micro-flow gas transport and detection are expensive, which is not conducive to the popularization of low-end civilian use. Contents of the invention [0003] The problem to be solved by the present invention is to provide a cheap pipeline gas flow signal acquisition device capable of detecting trace gas flow. [0004] In order to solve the above-mentioned technical problems, the pipeline low-pressure micro-flow gas flow signal acquisition device of the present invention includes a housing, which is provided with an inlet pipe interface and an air outlet pipe interf...
