The novel measuring cup has the advantages that the function of being capable of measuring the volume of liquid is additionally achieved, the intensity of pressure of the liquid on the measuring cup is reduced, the accuracy of measurement results is improved, and the measurement requirements for high capacity, low intensity of pressure and high precision are met.
Description
Technical field
The utility model belongs to liquid detecting and fields of measurement, especially relates to a kind of novel measuring cup.
Background technology
In existing technology, the volume of the liquid that wide-mouth measuring cup is measured is little and precision is not high, and error is 10%～25%; The volume of the liquid that bucket formula weight cup is measured is slightly large, the maximum 5000mL that reaches at present, but measuring accuracy is not high, and error is 10%～30%; The precision that standard measuring cup is measured is high, and error is 3%～5%, but the liquid volume that can measure is limited, and the maximum volume that can measure is 1000mL; The error that the special-shaped measuring cup such as volumetric flask is measured is between 3%～5%, and the liquid maximum volume that can measure is at present 1500mL.When measuring large volume liquid, for guaranteeing measuring accuracy, if the standard of use measuring cup is measured, need to increase the height of measuring cup, but liquid can be to producing larger pressure at the bottom of measuring cup cup.In a word, when existing measuring cup is measured liquid volume, exist and measure the liquid of large volume and the technical matters that measuring accuracy can not be simultaneously satisfied.
Summary of the invention
Problem to be solved in the utility model is to provide a kind ofly can measure the novel measuring cup that large volume liquid can improve again measuring accuracy, is especially applicable to liquid detecting and fields of measurement.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel measuring cup, comprise closed cup and small-bore pipeline, described small-bore pipeline runs through described cup, and it is outside that its upper and lower two ends are all positioned at described cup, and the tube wall that is positioned at the described small-bore pipeline of described cup inside is provided with through hole.
Described cup comprises sidewall, upper bowl cover and lower bowl cover, and described small-bore pipeline upper end is closely connected with described upper bowl cover, and described small-bore pipeline lower end is closely connected with described lower bowl cover.
In described small-bore pipeline, there is a float.
Tube wall place, described small-bore pipeline lower end is provided with lower contact-making switch, and tube wall place, described small-bore pipeline upper end is provided with contact-making switch.
Described lower contact-making switch is positioned at the top of described small-bore pipeline lower port.Described small-bore pipeline between described lower contact-making switch and described small-bore pipeline lower port has the effect of buffering liquid.Liquid enters described measuring cup, after buffering a period of time, when the described lower contact-making switch of described small-bore pipeline lower end detects described float, metering starts, increase along with liquid, described float moves up along the inwall of described small-bore pipeline, and when the described upper contact-making switch of described small-bore pipeline upper end detects described float, metering finishes.
Described number of openings is more than 1.Described through hole can make the liquid level in described cup and described small-bore pipeline be consistent.
The central axis of described small-bore pipeline and the central axes of described cup.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, solved the little problem of liquid volume that traditional measuring cup can be measured, reduced the pressure of liquid to measuring cup simultaneously, thereby overcome the low problem of precision while measuring large volume liquid, make to measure liquid volume convenient accurate, met large capacity, low pressure and high-precision requirement, have simple in structure, the advantages such as it is convenient to measure, and processing cost is low.

Embodiment
The present embodiment is a kind of novel measuring cup, as shown in Figure 1, comprise cup 1 and small-bore pipeline 2, cup 1 volume is 20L, cup 1 bottom is connected with lower bowl cover 8, cup 1 top is connected with bowl cover 7, small-bore pipeline 2 runs through cup 1 inside, small-bore pipeline 2 upper ends are positioned at cup 1 outside and are closely connected with upper bowl cover 7, small-bore pipeline 2 lower ends are positioned at cup 1 outside and are closely connected with lower bowl cover 8, be positioned on the small-bore pipeline 2 of cup 1 inside and there are 20 at the equidistant through hole 3 of tube wall homonymy, in small-bore pipeline 2, there is float 4, float 4 is stainless steel hollow ball, between lower bowl cover 8 and small-bore pipeline lower port 9, be provided with lower contact-making switch 6, lower contact-making switch 6 gos deep into 5mm from the tube wall outside of small-bore pipeline 2 to this tube wall, small-bore pipeline 2 upper ends are provided with contact-making switch 5, upper contact-making switch 5 gos deep into 5mm from the tube wall outside of small-bore pipeline 2 to this tube wall, upper contact-making switch 5 and lower contact-making switch 6 are metal switch.
As shown in Figure 2, the utility model can be applied to flowmeter monitor station.Flowmeter monitor station comprises fluid reservoir 10, conduit, flowmeter to be detected 11 and measuring cup 12, fluid reservoir 10 is connected by conduit with flowmeter 11 entrances to be measured, the small-bore pipeline lower port 9 of measuring cup 12 is connected with flowmeter 11 outlets to be measured by conduit, small-bore pipeline 2 tops of measuring cup 12 are connected with measuring cup bleeder pipe 14, and measuring cup bleeder pipe 14 is provided with measuring cup air escape cock 13.In order to reduce liquid, thereby the pressure of measuring cup 12 is improved to measuring accuracy, when measuring cup 12 is used and between surface level, have an angle, between 0～90 °.Liquid flows out from fluid reservoir 10, flows through in the rear inflow measuring cup 12 of flowmeter 11 to be measured.Lower contact-making switch 6 in measuring cup 12 starts metering while float 4 being detected, when upper contact-making switch 5 detects float 4, metering finishes, observe flowmeter 11 registration showing and the volume measuring with measuring cup 12 to be measured, after comparative analysis, obtain the precision of flowmeter 11 to be measured.According to the difference for the treatment of 11 accuracy requirements of measurement of discharge meter, select not isometric measuring cup 12, by changing the volume of the bore of measuring cup 12 cups 1 and the length adjustment measuring cup 12 of cup 1, the volume of the higher measuring cup of selecting 12 of flowmeter 11 accuracy requirements to be measured is larger.
The course of work of this example: measuring cup 12 is used in flowmeter monitor station, and the angle between measuring cup 12 and surface level is 75 °.Liquid flows out from fluid reservoir 10, liquid enters in the small-bore pipeline 2 between small-bore pipeline lower port 9 and lower contact-making switch 6 after by flowmeter 11 to be measured, liquid flow tends to be steady, when detecting float 4, the lower contact-making switch 6 of small-bore pipeline 2 bottoms starts metering, along with the increase of liquid, liquid level rises, and float 4 rises along small-bore pipeline 2 inwalls, when the upper contact-making switch 5 on small-bore pipeline 2 tops detects float 4, metering finishes, and the error of measurement is in 0.05% left and right.The liquid volume that the present embodiment is measured is 12 maximum volumes that can measure of whole measuring cup, has realized large capacity, low pressure and high-precision measurement requirement, thereby has guaranteed the degree of accuracy that flowmeter to be measured detects.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
