Standard pipeline structure with moving rail

Abstract

The invention discloses a standard pipeline structure with a moving rail. The structure comprises a pipeline body, the pipeline body comprises a plurality of pipelines of different pipe diameter sizes, large-diameter pipelines sleeve a plurality of small-diameter pipelines and the large-diameter pipelines and the small-diameter pipelines are rotatably provided with sealing parts and positioning devices which guarantee pipeline coaxiality; the pipeline body is composed of a long pipeline, a short pipeline and a movable connecting short pipe connected between the long pipeline and the short pipeline; the long pipeline, the short pipeline or the connecting short pipe is composed of a plurality of pipe segments of different pipe diameter sizes in an inserted and embedded mode; the pipelines having the same pipe diameter of the long pipeline, the short pipeline and the connecting short pipe can be mutually connected to form a standard pipeline with a specific pipe diameter; a rail moving device capable of translating the long pipeline is installed under the long pipeline. The structure is suitable for liquid flow standard devices of different standard requirements to use, and can effectively reduce cost of purchasing equipment. The standard pipeline conveniently and rapidly changes pipe diameters, and effectively improves the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of fluid measurement, and relates to a liquid flow standard device, in particular to a calibration pipeline structure with a moving track. Background technique [0002] The existing flow standard devices are either standard meter liquid flow standard devices, static mass method flow standard brick devices or other standard devices; they all have independent water pools / tanks, water pumps, buffer tanks, meter clips, and calibration pipelines , Control valves, electrical control systems, power supply systems and control and calculation software systems; not only requires a larger workshop area during the construction process, but also increases equipment investment and construction period. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a calibration pipeline structure with a moving track, which can be ap...
