Beschreibung
Zusammenfassung:	PURPOSE:To provide a structure for an indoor pipeline, which is capable of eliminating the malfunction of an emergency shut-off valve provided for a gas burner originally, by avoiding the affection of a gas pressure increase as a result of the change of atmospheric temperature in the indoor pipeline and the like, to customers, to whom gas is supplied through an exclusive pressure regulator or a house regulator, effectively. CONSTITUTION:In a structure of indoor pipeline, equipped with a gas pressure regulating mechanism 9 at the inlet site of an indoor pipeline and an emergency intercepting valve 10 for the time of malfunction of the gas pressure regulating mechanism 9, a pressure buffer mechanism 12 for maintaining the inner pressure of the indoor pipeline at a gas pressure lower than a high pressure side emergency shut-off pressure, whereat the shut-off operation of the emergency shut-off valve 10 is operated, is provided at the site 11 of an indoor pipeline on the downstream side of the emergency shut-off valve 10.
