Basic dataStandard ID: GB/T 2624.4-2006 (GB/T2624.4-2006)Description (Translated English): Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full -- Part 4: Venturi tubes Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: N12 Classification of International Standard: 17.120.10 Word Count Estimation: 24,229 Date of Issue: 2006-12-13 Date of Implementation: 2007-07-01 Older Standard (superseded by this standard): GB/T 2624-1993 Quoted Standard: GB/T 2624.1-2006; GB/T 17611-1998 Adopted Standard: ISO 5167-4-2003, IDT Regulation (derived from): China Announcement of Newly Approved National Standards No. 13 of 2006 (No. 100 overall) Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies the venturi tube geometry and installed in a pipe full pipe fluid flow measurement using the method (installation and operating conditions). GB/T 2624 is also provided in this section may be used to calculate the flow rate with GB/T 2624. 1 requirements together with the relevant information. GB/T 2624 applies only to this part of the entire measurement period in subsonic flow of fluid retention, and can be considered a single -phase flow venturi. In addition, each device may only be required for pipe size, roughness, diameter than the Reynolds number limits. GB/T 2624 does not apply to this part of pulsating flow measurements. This section does not involve the venturi tube 50mm or greater in size to less than 1200mm, or pipe Reynolds than 2 �� 10 ^ 5 the use of a pipe. GB/T 2624 This part involves three types of classical Venturi tube: a) foundry, b) mechanical processing, c) thick solder iron type. Venturi inlet pipe is cylindrical segment, conical contraction, cylindrical and tapered diffuser throat in turn connected in an apparatus. Three types of classical Venturi tube discharge coefficient uncertainty value of the difference between the one hand that each type of classical Venturi tube number of existing experimental results, suggesting that other geometric contour precisely defined uncertainty extent. These values ??are based on data collected over the years. Venturi nozzle (and other nozzles) by the GB/T 2624. 3 exposition.
