Problems solved by technology

However, the surface tension of the glass float meter in the sulfuric acid aqueous solution is very large. In order to eliminate the influence of the surface tension, the overflow method is required in the verification regulations.
[0004] ISO649 / 2 has regulations on the overflow cylinder, which is divided into three specifications: 200ml, 400ml, and 800ml. Due to the small volume, the volume of the overflow cylinder in JJG86-2011 Standard Glass Float Meter Verification Regulations and JJG42-2011 Working Glass Float Gauge Verification Regulations is 5000ml or so, which causes the surface tension to be irreversible

Embodiment

[0015] Embodiment: The size of the existing overflow tank is enlarged to 1000ml. The function of the expansion is to meet the comparison of two glass floats with larger diameters in the overflow tank. Select the standard glass buoyancy for measurement (note: the diameter of the standard glass buoyancy gauge is 23.9mm, the diameter of the standard glass buoyancy gauge is the largest of the glass buoyancy gauge, choose twice the diameter of the standard glass buoyancy gauge as the reference value for the diameter of the calibration overflow cylinder, such as 60mm~65mm).

[0016] ISO649 / 2 has three specifications for the overflow cylinder: 200ml, 400ml, and 800ml. The sizes are not large, and they meet the need to eliminate surface tension during measurement, not for verification. In order to prevent the enlarged size from affecting the measurement results during the verification process, a circle of gold wire is added to the inner wall of the overflow plane of the overflow tube ...

Abstract

The invention discloses an overflow cylinder for testing a glass buoyancy gauge, which comprises a cylinder body and an overflow opening, and the overflow opening is inlaid with gold. This patent refers to the provisions of ISO649 / 2 on the overflow cylinder, measures the maximum diameter of the first-class standard glass float gauge, changes the volume of the overflow cylinder and adds gold wires of gold materials at the overflow port, effectively reducing the liquid surface of the overflow cylinder wall The effect of tension on the diameter of the buoyancy stem.

Description

technical field [0001] The invention relates to an overflow cylinder for verification. Background technique [0002] The measurement of liquid density is usually measured by a glass float meter in the manufacturing industry. The value of the glass float meter is traceable. The current national verification regulations JJG86-2011 standard glass float meter verification regulations, JJG42-2011 working glass float meter verification procedures. [0003] Glass float meter 1000kg / m in production 3 ~1830 kg / m 3 , is the buoyancy value of the buoyancy meter in aqueous sulfuric acid solution for calibration. However, the surface tension of the glass float meter in the sulfuric acid aqueous solution is very large. In order to eliminate the influence of the surface tension, the overflow method is required in the verification regulations. [0004] ISO649 / 2 has regulations on the overflow cylinder, which is divided into three specifications: 200ml, 400ml, and 800ml. Due to the small...
