摘要： An instantaneous, automatic gas water heater for a hot water system having a cold water supply conduit connected to a plurality of loosely wound small heat exchange tubes which, in turn are connected to a hot water outlet conduit having faucets. The heat exchange tubes are each of smaller internal diameter than the cold and hot water conduits but their total capacity is substanially the same as said conduits. A gas burner is disposed beneath the heat exchange tubes to subject them to the flame of the burner. There is a cover over the heat exchange tubes which confines the heat from the burner about the tubes. The burner is supplied with gas by a gas supply conduit controlled by a normally closed solenoid valve including a gas control valve and a solenoid controlling the gas control valve. There is an electrical system for the solenoid valve and said electrical system includes a diaphragm controlled switch with the diaphragm subjected to water pressure in one of the conduits such as the cold water inlet conduit.There is also an adjustable temperature control thermostat mechanism subjected to and controlled in accordance with the temperature in the hot water conduit for controlling a second solenoid valve which controls gas to the burner.
摘要翻译： 一种用于热水系统的瞬时自动燃气热水器，其具有连接到多个松散缠绕的小型热交换管的冷水供应管道，冷管道又连接到具有龙头的热水出口管道。 热交换管的每一个的内径都比冷水和热水管的内径小，但它们的总容量基本上与所述导管相同。 气体燃烧器设置在热交换管的下方以使其经受燃烧器的火焰。 热交换管上有一个盖子，它将来自燃烧器的热量限制在管子周围。 燃烧器由通过常闭电磁阀控制的气体供应管道供应，该常闭电磁阀包括气体控制阀和控制气体控制阀的电磁阀。 电磁阀具有电气系统，并且所述电气系统包括隔膜受控开关，隔膜在其中一个导管（例如冷水入口导管）中经受水压。
