从标准视角解析燃气自动截止阀的安全设计
Analysis of Safety Design of Gas Automatic Shut-off Valves from Standard Perspective
摘要
Abstract
The international standard Safety and Control Devices for Gas Burners and Gas-burning Appliances-Particular Requirements-Part 1:Automatic and Semi-automatic Valves(ISO 23551-1:2012)is studied.The key indexes of safety design of gas automatic shut-off valves,such as non-programmed operation closure,air tightness,sealing force and durability,are analyzed.In conjunction with the formulation and implementa-tion of the standard Safety and Control Devices for Gas Burners and Gas-burning Appliances-Particular Requirements-Automatic and Semi-automatic Valves(GB/T 37499-2019),the paper proposes that during the safety design of automatic shut-off valves,particu-lar attention should be paid to the spring closing force before and after durability testing,residual magnetism of the valve core before and after durability testing,ma-chining accuracy of the valve seat,flatness and machin-ing accuracy of the sealing gasket.关键词
