Description
Technical field
The utility model relates to the rectifier technical field, is specifically related to a kind of gasotron.
Background technology
The flowmeter of existing fluid metering all is not provided with rectifier usually, but for the demanding commercial unit of some accuracies of measuring, is the accurate measurement that improves fluid flow, has in the upper reaches that are employed in flowmeter and the pipeline that flowmeter links to each other rectifier is set yet.And the rectifier that adopts at present is that some calibers small tubes identical with length is set in pipeline; When making fluid flow through this segment pipe; Pass through from the gap between these small tubes and small tubes respectively; Make the flow state of fluid through rectifier the time obtain adjustment and tend to be steady, the accuracy that helps measuring is improved.But because the existing length of forming the small tubes of rectifier is 3 ~ 30 times of set pipe diameter; The caliber that is equipment pipe is 100mm; The length of rectifier small tubes will be 300 ~ 3000mm; Oversize because of the length of rectifier, can not be installed in the flowmeter, have only the outer upstream extremity that is connected on flowmeter.And the long rectifier of this length, can also cause fluid pass through reduced cross-sectional area after, the of short duration jet state of generation when long small tubes downstream end flows out; Influence rectification effect, so the rectifier of this structure, volume is bigger; The material that adopts is more; Cost is high, and will increase the installation connecting link of pipeline, has also increased simultaneously because of connecting the leakage hidden danger of poor sealing; And adopting its metering of rectifier of this structure still to have the error about 7%, the accuracy of metering is still waiting further raising.
Summary of the invention
To the deficiency that prior art exists, the gasotron that the purpose of the utility model is that a kind of compact conformation is provided, cost is low, measuring accuracy is high and effective elimination distortion fluid disturbs.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of gasotron; Comprise the rectification cylindrical shell, have inlet end and endpiece on the said rectification cylindrical shell, the inlet end of this rectification cylindrical shell is equiped with first rectifier cell; Be equiped with first diversion member near said first rectifier cell the inner; This first diversion member the inner is equiped with second rectifier cell, and said first rectifier cell is a circular ring structure, and circle ring inner surface is provided with several and is evenly distributed on the rectiblock on the same diameter circumference; Said second rectifier cell is a column structure, and the said second rectifier cell outside surface is provided with the some reinforcements that are evenly distributed on the same diameter circumference.
Through adopting technique scheme, embedded being installed in the rectification cylindrical shell of parts constituted integral structure, make the utility model compact conformation, cost is low, and can effectively eliminate the distortion fluid and disturb, thereby improves measuring accuracy.
The utility model further is set to: four reinforcements are set on said second rectifier cell, and these four reinforcements and second rectifier cell be wholely set, said four reinforcements constitute " ten " font structure.Through this setting, structure is more reasonable, and rectification effect is best.
The utility model also further is set to: the endpiece of said rectification cylindrical shell is equiped with second diversion member; Be equiped with watch core bearing and impeller between said second rectifier cell and second diversion member; Said impeller is installed between the watch core bearing and second diversion member, and impeller is rotatable is matched with on the watch core bearing.Through this setting, make that the utility model measuring accuracy is higher.
The utility model also further is set to: said first rectifier cell, first diversion member, second rectifier cell, watch core bearing and second diversion member all are fixedly connected with the inwall of rectification cylindrical shell.Through this setting, make structure compact more, and parts adopt fixed connection to make the utility model constitute an integral body.
The utility model has the advantages that: because to the appropriate design of the structure of first rectifier cell and second rectifier cell and the reasonable arrangement of two rectifier cell locations of structures; Make the utility model compact conformation; Effectively eliminating the distortion fluid disturbs; Compare with traditional flowmeter, this design can reach the rectification effect of former twice straight length.Guarantee under nonideal flowmeter mounting condition, can high-precisionly to measure.
Below in conjunction with Figure of description and embodiment the utility model is further described:
