Description

Internal diameter of the pipeline detection means
Technical field
Industrial application is the utility model is related to, particularly a kind of internal diameter of the pipeline detection means.
Background technology
, it is necessary to many pipeline and the instrument G.I.Hs that will be serially connected in oil extraction in oil field industrial processes, to adopt The operation process such as oil provide transmission channel.The internal diameter of pipeline and instrument is very important for ball-throwing type such as builds the pressure at the operation Parameter, thus before actual use, operating personnel needs to detect the internal diameter of pipeline and instrument in itself, to determine that it is It is no to adapt to operation in ensuing well.
Conventional detection method is will to be put into the detection ball for determining diameter in the pipeline or instrument being vertically arranged, with logical Gravity is crossed to be detected.Specifically, if detection ball has been smoothly through pipeline or instrument, then illustrate pipeline or instrument most Small internal diameter is more than the diameter of detection ball;If detection ball is not smoothly through pipeline or instrument, then illustrates the pipeline or work The minimum diameter of tool is less than the diameter of detection ball.This method is needed the different detection ball input pipeline of at least two diameters or work The minimum diameter of the pipeline or instrument could be determined within the specific limits in tool.In addition, pipeline or instrument is set usually can vertically Limited by work site conditions, and the difficulty of field operation can be increased, and larger potential safety hazard be present.Therefore using above-mentioned Method is tested to be inconvenient for operating personnel.For longer pipeline, with this method of testing Tested even more very difficult.
Therefore, it is necessary to a kind of detection means for the internal diameter that can more easily detect pipeline or instrument.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of internal diameter of the pipeline detection means, can be more by this device Add and easily internal diameter of the pipeline is detected.
According to the utility model proposes a kind of internal diameter of the pipeline detection means, it includes light source and relative with the light source set The first receiver put, the light source and first receiver are separately positioned on the both ends of pipeline.
This internal diameter of the pipeline detection means make use of light caused by light source in the principle of pipeline interior edge straightline propagation.If Light reaches the first receiver, then and just explanation light is not stopped inside pipeline, thus the minimum diameter value of pipeline Half is more than now the distance between center of light source and pipeline;If light does not reach the first receiver, then just explanation light Line receives obstruction inside pipeline, thus the half of the minimum diameter value of pipeline should be less than now light source and pipeline center it Between distance.Detected by this device and necessarily require that pipeline is placed vertically, pipe level placement or slant setting are all It is possible.Therefore, detected using this device it is smaller to limitations such as place and operations, hence for operating personnel come Say, using this device test very convenient.Managed further, since carrying out test using this device and being not required to vertical place Road, therefore can also effectively avoid the generation of security incident, it is ensured that the personal safety of operating personnel.Come for longer pipeline Say, this is especially advantageous.
In one embodiment, the first receiver includes transparent cover plate.The setting of transparent cover plate causes light source to produce Light can pass through cover plate and easily be observed by operating personnel.This make it that the structure of the first receiver is more succinct, and Measurement result can be obtained intuitively by operating personnel very much.
