Область применения
This standard specifies the patterns, specifications, and basic parameters for fire screw-type couplings. It is specifically applicable to suction hose couplings, blank caps, and same-type couplings used in fire water supply systems. Engineers manufacturing fire-fighting water delivery components must comply with this standard. It is not applicable to internal expansion or snap-type couplings covered in other parts of the GB 12514 series.
Технические требования
The standard outlines the structural and dimensional requirements for screw-type fire couplings. It defines three main coupling types: KG (suction hose coupling), KA (blank cap), and KT (same-type coupling). The applicable medium is restricted to water. The standard sets specific nominal diameters ranging from 90mm to 150mm and nominal pressures of 1.0 MPa and 1.6 MPa. Chapters 4 and 5 regarding structural design and basic dimensions are mandatory. Dimensional tolerances for unmarked dimensions must comply with GB/T 1804-2000 (general tolerances). The standard also provides a specific marking method to identify the coupling type, nominal diameter, and pressure.
Методы испытаний
While specific testing procedures are not detailed in this part, compliance is verified through structural inspection and dimensional measurement. The coupling structures must conform to the designated reference diagrams, and all basic dimensions must meet the specified tolerance limits outlined in the standard's parameter tables.
Частые вопросы
