17、 Introduction On the market, a series of geometries (outside threaded pipe G A with inside cone and counter geometries), e.g. under the designation “eurocone”, is commonly used. These geometries, however, are compatible with each other only to a limited degree. Therefore, this European Standard is i
18、ntended to achieve a unification of detachable connections with outside threaded pipe G A and inside cone. Significant known applications are: connection geometries of radiators with integrated valves; connection geometries of connection fittings and bypass connection fittings on radiators with inte
19、grated valves; connection geometries of ascension pipe valves for standard radiators; connection geometries of heating circuit distributors to underfloor heatings and radiator connection systems; interface between radiator nipple and thermostatic valve or lockshield valve. Detachable connections wit
20、h the outside threaded pipe G A are normally made of metallic materials. Further variants are possible. So far, the designation “eurocone” has conveyed the impression that there is a standardised geometry. However, this is not the case, i.e. the screw in or thread lengths, the cone angles and diamet
21、ers, as well as the diameter of the inner cylinder differ frequently. Furthermore, the following variants are commonly used: spherical or tapered cone; cones with and without inserted sealing material; sealing principles inside the cylindrical part of the geometry comprising O rings; O rings within
22、the slope of the cone (O rings offered by different providers are designed for different press fits); and sealings without additional sealing material (metallic sealing). DIN EN 16313:2013-08EN 16313:2013 (E) 5 1 Scope This European Standard applies to detachable connections with outside threaded pi
23、pe G A in accordance with EN ISO 228-1. These are used in the field of heating and cooling emission systems at the following hydraulic connection points: connection between radiators or circuit distributors and the respective pipe. Another connection point, for radiators with integrated valve sets,
24、is the screw connection to the connection fitting or to the screw connection itself. This European Standard specifies the dimensions for the single and the double connection. 2 Normative references Not applicable. 3 Dimensions and designs Dimensions in millimetres Surface roughness in micrometres Ke
