Fig. 2 is the flow measurement pipeline structural representation being provided with clearing apparatus;
The structural representation of Fig. 3 clearing apparatus;
Fig. 4 is the structural representation of overcoat;
Fig. 5 is the structural representation of seal.
Embodiment
Below in conjunction with specific embodiment, the utility model is further expalined, but is not limited to protection domain of the present utility model.
In order to solve in flow measurement pipeline in the past owing to there is the impurity such as the dust that is difficult to clean, cause the inaccurate problem of the measurement of flow, present embodiment provides the clearing apparatus for flow measurement pipeline, see Fig. 2, this clearing apparatus is communicated with flow measurement pipeline 1 to be installed, and bottom the upstream line being positioned at flowmeter 2 or be positioned at pipeline place below flowmeter 2, wherein, that this clearing apparatus to be arranged on pipeline place below flowmeter 2 be example in Fig. 2, this clearing apparatus is see Fig. 3, form primarily of overcoat 3 and seal 4, and see Fig. 4, this overcoat 3 comprises the first pedestal 31, the central authorities of the first pedestal 31 are provided with through hole 311, the connecting leg 32 upwards extended is provided with in the periphery of through hole 311, and the upper end of connecting leg 32 is connected by being welded and fixed with described flow measurement pipeline 1, see Fig. 5, seal 4 comprises the second pedestal 41, and above the second pedestal 41, be fixedly installed the shutoff 42 upwards extended, and described shutoff 42 is inserted in the connecting leg 32 of overcoat 3, and described second pedestal 41 connects with the first pedestal 31.
By the setting of this clearing apparatus, the cleaning of the impurity such as dust in flow measurement pipeline 1 can be facilitated, when needs carry out pipe-line purging, seal can be taken out from overcoat, cleaning device is stretched in pipeline or at overcoat place by overcoat and is connected with dust sucking plant, thus complete the cleaning of pipeline, after cleaning terminates, again seal is installed in overcoat, prevent ducted fluid from leaking, by the design of this clearing apparatus, greatly facilitate the cleaning of pipeline, thus make the actual circulation area of fluid consistent with the xsect of pipeline, to improve the degree of accuracy of flow measurement.
