Abstract
A flow calibrator comprises a measuring device, an end cap and a connecting device. The measuring device is connected with the end cap. The flow calibrator is characterized in that the measuring device comprises a liquid level indicating device which is a floater type liquid level indicating device, so that reading accuracy of users is increased, and particularly, when the flow calibrator is used for calibrating colorless transparent chemical liquid, the end cap can be removed, thereby bringing convenience for cleaning liquid attached on the cylindrical inner wall of the flow calibrator. The flow calibrator is mainly used for metering of chemical treatment industries and accurately counting chemical liquid added in industrial flow pipelines by chemical feed pump systems, and is mainly used for metering of chemical treatment industries and flow calibration of chemical feed pump systems.
Description
Technical field
The utility model relates to the Calibration Column in a kind of fluid system, more properly relates to the metering of chemical treatment industry and the flux scale fixed column of dosing pump system.
Background technology
In volume pump or medicine system, the user needs the regular chemical liquid to adding industry stream pipeline to carry out precise counting.Volume pump itself can not be assessed accurately to flow, so need a Calibration Column to finish this work.Basically, Calibration Column should be placed between fluid reservoir and the volume pump.During work, the valve that is used for isolating fluid reservoir will be closed, and volume pump will suck liquid from Calibration Column the inside.When Calibration Column is drained, the volume of discharging in the unit interval will provide the accurate flow of volume pump.When Calibration Column did not use, the isolation valve that connects Calibration Column cut out.
Therefore existing Calibration Column all is the glass flow rate Calibration Column, but when liquid was water white transparency, the operator can't differentiate the concrete scale above the Calibration Column, correct reading.
The utility model content
At the problem of above-mentioned existence, the utility model provides a kind of Calibration Column, comprises measurement mechanism, end cap, coupling arrangement, and described measurement mechanism links to each other with end cap, it is characterized in that measurement mechanism comprises a level instruction device.
Described level instruction device is can be with liquid level rising or the device that descends.
Described level instruction device is a sheet-type device.
Described level instruction device is a floating sheet.
Described floating sheet is positioned at the inside of measurement mechanism.
Described coupling arrangement is NPT and BSPT screw connection, and ASTM is connected six kind coupling arrangements one of with ANSI with the DIN flange with DIN socket coupling arrangement.
Described measurement mechanism is transparent plastic tube.
Comprise at least one packoff.
Described packoff is to be one O type circle to small number.
Described O type circle is positioned at the inside groove of end cap.
The beneficial effect of technique scheme:
1. adopt the level instruction device of floating chip, improved the degree of accuracy of user's reading, particularly water white chemical liquid has been carried out timing signal;
2. end cap can remove, and is convenient to the cleaning attached to the transparent or opaque liquid of tube inwall.

Embodiment
Below in conjunction with Fig. 1 the utility model implementation column is carried out concrete description:
As Fig. 1. shown in Figure 2, the liquid indicating device is a floating sheet 7 in the present embodiment, measurement mechanism is connected with end cap, measurement mechanism is a transparent plastic tube 4, nonvolatil connecting together between end cap 5 and the plastic tube 4, end cap 1A and transparent plastic tube 4 are combined together by the socket connected mode, and the hole that gas is discharged is arranged on end cap 1A, floating sheet 7 is positioned at 4 li of transparent plastic tubes, and this device must vertically be installed and could normally use.
By hand or the diverting valve liquid that will need to inject be circulated in the Calibration Column, arrive the position of its top scale mark.Before beginning, guarantee valve closing.Open volume pump and all be excluded up to the air of its all suction lines and pump head, close volume pump then successively, valve-off #2 opens valve #1.Open volume pump, measure the volume (milliliter or gallon) that it pumped in the Calibration Column in 60 seconds.If use the milliliter scale, multiply by 60 again and just obtain flow hourly (milliliter/hour).Known this flow, regulated volume pump up to the flow value that meets expectation.When not using, isolation valve (valve #1) cuts out to Calibration Column.
Embodiment two
Shown in Figure 3, unique difference of present embodiment and embodiment one is, an inside groove is arranged on end cap 1B, between end cap 1B and the transparent plastic tube 4 packoff arranged, and packoff is an O type circle, and the quantity of O type circle is one, and O-ring seal is positioned on the inside groove of end cap 1B.
Other embodiment of the present utility model and embodiment one different are the different of end cap and transparent connected mode that who knows pipe, and its connected mode is the BSPT screw connection, and STM one of is connected with the DIN flange with NSI with DIN socket coupling arrangement.
Although the utility model instructions has been done detailed explanation and has been quoted embodiment as proof, but for those of ordinary skill in the art, obviously can make various replacement schemes, modification and change according to above-mentioned explanation, comprise the selection of material, therefore, all these replacement schemes, correction and change all should be included within the spirit and scope of claim.
