適用范圍

This document specifies constructional, functional, testing and marking requirements, sizing and documentation of gas safety shut-off devices used in the pressure regulating stations in accordance with EN 12186 or EN 12279: - for inlet pressures up to 100 bar and nominal diameters up to DN 400; - for an operating temperature range from –20 °C to +60 °C, which operate with fuel gases of the 1st and 2nd family in accordance with EN 437 in transmission and distribution networks and also in commercial and industrial installations. "Gas safety shut-off devices" will hereafter be called "SSDs" except in titles. For standard safety shut-off devices when used in pressure regulating stations complying with EN 12186 or EN 12279, Annex ZA lists all applicable Essential Requirements except the external corrosion resistance in case of environmental conditions where corrosion is likely to occur." This document considers the following classes/types of SSDs: temperature classes: - class 1: operating temperature range from –10 °C to 60 °C; - class 2: operating temperature range from –20 °C to 60 °C; functional classes: -class A: SSDs that close when damage to the pressure detector element occurs (applicable to overpressure SSDs only) or when external power fails and whose re-opening, after an intervention for overpressure, is possible only manually; - class B: SSDs that do not close when damage to the pressure detector element occurs and whose reopening, after an intervention for overpressure, is possible only manually; SSDs types: - type IS: (integral strength type); - type DS: (differential strength type). SSDs complying with the requirements of this document may be declared as “in conformity with EN 14382“ and bear the mark “EN 14382”. The material and functional requirements specified in this document may be applied to SSDs which use thermal energy or the effects of electrical energy to trip the operation of the closing member. For these SSDs the operational parameters are not specified in this document. This document does not apply to: - SSDs upstream from/on/in domestic gas-consuming appliances which are installed downstream of domestic gas meters; - SSDs incorporated into pressure-regulating devices used in service lines with volumetric flow rate ≤ 200 m3/h at normal conditions and inlet pressure ≤ 5 bar.
