Liquefied Petroleum Gas Systems and Equipment for Residential and Commercial Users in Japan
摘要
Abstract
Drawing on the advanced experience of residential and commercial users in Japan in ensu-ring the safety of LPG systems,suggestions are put for-ward to reduce LPG accidents in China.The construc-tion of gas alarm control system is strengthened.The a-larm control system of the LPG system for residential users in Japan is composed of in-telligent gas meters,LPG leakage alarms and CO a-larms,and the alarm control system of the LPG system for commercial users is composed of commercial auto-matic gas shut-off devices,LPG leakage alarms and CO alarms,forming a safety guarantee system for LPG systems.LPG cylinders are stored outdoors.Japan's LPG cylinders are placed in a fixed position outdoors to effectively reduce the possibility of LPG gathering in-doors after a leak.The research and development and application of new equipment are strengthened.In ad-dition to the basic pressure regulation function and shutdown function,the automatic switching regulator can automatically switch to the spare side cylinder and supply gas with the use side cylinder at the same time when the LPG supply of the use side cylinder is insuffi-cient.The technical research is focused on.The ten-sion anti-outgassing high-pressure hose can prevent LPG leakage caused by earthquakes,so as to avoid secondary disasters caused by earthquakes.关键词
