The position corresponding with the inlet of overflow pipe is provided with volume graduation mark on the cylinder.
The cylinder is transparent tube.
It is described to exempt to read graduation mark liquid dispensing device specified to measure volume following by the inlet in cylinder with overflow pipe
Determined along the volume of concordant horizontal line to the upper end of the first valve.Can require to make different specified according to different in practical application
Volume exempt from read graduation mark liquid dispensing device.Reading graduation mark liquid dispensing device of exempting from of the present utility model make use of linker
Operation principle, when closing the first valve, opening the second valve, to liquid to be measured is toppled in cylinder, when liquid passes through overflow
Pipe stops pouring liquid when flowing into overflow pipe, after the liquid flow in overflow pipe is complete, the first valve is opened, by raffinate in cylinder
Body is poured into container, and the liquid volume poured into is the nominal volume for exempting to read graduation mark liquid dispensing device.
Compared with prior art, the beneficial effects of the utility model are：
Reading graduation mark liquid dispensing device of exempting from of the present utility model can measure the liquid of fixed volume, and easy to operate, essence
Exactness is high, it is to avoid the deviation of reading of range estimation graduation mark, can realize the quick measurement of liquid volume.
Brief description of the drawings
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation for exempting to read graduation mark liquid dispensing device of the present utility model；
In figure：1st, cylinder；2nd, feed tube；3rd, drain pipe；4th, the first valve；5th, overflow pipe；6th, the second valve.
Specific embodiment
Embodiment of the present utility model is described in detail below in conjunction with embodiment, but those skilled in the art
Member will be understood that the following example is merely to illustrate the utility model, and is not construed as limiting scope of the present utility model.
Reference picture 1, the utility model exempts to read graduation mark liquid dispensing device there is provided one kind, including for holding liquid
Cylinder 1, the upper end of cylinder 1 is provided with feed tube 2, and the lower end of cylinder 1 is provided with drain pipe 3, the first valve 4 is provided with drain pipe 3；
The side of cylinder 1 is communicated with overflow pipe 5, and the second valve 6 is provided with the liquid outlet of overflow pipe 5.Wherein, the feed tube 2 of cylinder 1
The drain pipe 3 with diameter greater than cylinder 1 diameter.Above-mentioned reading graduation mark liquid dispensing device of exempting from is made by transparent material,
Transparent material can be the other materials such as clear glass or transparent plastic.
It is above-mentioned to exempt to read graduation mark liquid dispensing device specified to measure volume following by the inlet in cylinder with overflow pipe
Determined along the volume of concordant horizontal line to the upper end of the first valve.Can require to make different specified according to different in practical application
Volume exempt from read graduation mark liquid dispensing device.
It is of the present utility model to exempt to read the operation principle that graduation mark liquid dispensing device make use of linker, it is new using this practicality
When the exempting from of type is read graduation mark liquid dispensing device and carries out liquid and measure, first by the testing liquid rinse liquid dispensing device,
Then it is clamped in iron stand or other fixing devices, the level of use level instrument adjusting means, in the first valve and
The bottom of the pipe of two valves places the vessel for holding liquid, closes the first valve, opens the second valve, then is treated to toppling in cylinder
Measurement liquid, pouring liquid is stopped when liquid flows into overflow pipe by overflow pipe, and now, the liquid level in cylinder exceedes overflow pipe
The liquid of inlet lower edge will be flowed out by overflow pipe, after the liquid flow in overflow pipe is complete, open the first valve, this
When cylinder in remaining liquid will be flowed out by the first valve, loading hold in the vessel of liquid, the liquid bulk in this vessel
Product to be exempt from by the utility model reads the nominal volume that graduation mark liquid dispensing device is measured.
The utility model exempts from reading graduation mark liquid dispensing device can be required to make different according to different in actual applications
Nominal volume, nominal volume can be the arbitrary volume of 5mL, 10mL, 20mL, 50mL, 100mL etc..
In addition, the overflow pipe for exempting to read graduation mark liquid dispensing device of the present utility model there can be multiple, and it is vertically arranged
In the side of the cylinder, the liquid outlet of each overflow pipe is respectively arranged with valve, the inlet phase of cylinder and each overflow pipe
Corresponding position is respectively provided with volume graduation mark, represents different volumes, and now, the dispensing device just can measure different appearances
Long-pending liquid, when the liquid for needing to measure certain nominal volume, opens the valve of corresponding overflow pipe, you can completion measures work
Make, be achieved in one and exempt to read graduation mark liquid dispensing device that the purpose of different volume liquids can be measured, reduce liquid and measure
The quantity of device.
Using it is of the present utility model exempt from read graduation mark liquid dispensing device measure testing liquid when, easy to operate, high precision,
The deviation of reading of range estimation graduation mark is avoided, the quick measurement of liquid volume can be realized.
Needed in thermal power generation unit manufacture, capital construction installation and During Process of Long-term Operation at the scene to common steel (carbon steel,
Low-alloy pearlite steel, structural alloy steel, martensite steel, austenitic steel etc.) metal parts carry out the non-microstructure ruined
Inspection.In order to achieve the above object, metallographic test polishing fluid, aggressive agent need to be configured.When being measured using conventional graduated cylinder,
Need to read graduation mark, read graduation mark often bad student's reading error so that the liquid medicine of configuration to measure liquid volume not smart
Really, polishing fluid and aggressive agent quality is caused to decline.And entered using reading graduation mark liquid dispensing device of exempting from of the present utility model
Row is measured, and liquid volume can be accurately measured every time, such that it is able to enable polishing fluid and aggressive agent during metallographic test smart
True carrying out configures, such that it is able to more accurately carry out metallographic test, for thermal power plant high-temperature and pressure pipeline is provided more
Reliable technical support.
Obviously, those skilled in the art can carry out various changes and modification without deviating from this practicality to the utility model
New spirit and scope.So, if it is of the present utility model these modification and modification belong to the utility model claim and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising these changes and modification.
