标准范围

ISO 23551-3:2005规定了入口压力小于等于50 kPa、标称连接尺寸小于等于DN 250的气动式气体/空气比控制装置的安全、结构和性能要求，该控制装置用于燃气作为天然气、制造气体或液化石油气（LPG）的燃气器具。它还描述了评估这些要求的测试程序，并规定了安装和使用所需的信息。它适用于气体的气体/空气比控制-可以独立于设备进行测试的燃烧设备。它适用于气体/空气比率控制，其功能是控制气体压力（或压差）输出，以响应空气压力（或压差）和炉膛背压信号输入；但不排除根据气体压力改变空气压力的气体/空气比控制。它不适用于机械连接的阀门和电子系统。

ISO 23551-3:2005 specifies the safety, construction and performance requirements for gas/air ratio controls, pneumatic type, for inlet pressures up to and including 50 kPa, of a nominal connection size up to and including DN 250, intended for use with gas appliances using fuel gases as natural gas, manufactures gas or liquefied petroleum gas (LPG). It also describes the test procedures for evaluating these requirements and specifies information necessary for installation and use. It is applicable to gas/air ratio controls for gas-burning appliances that can be tested independently of the appliance. It is applicable to gas/air ratio controls which function by controlling a gas pressure (or differential pressure) output in response to an air pressure (or differential pressure) and to a furnace back pressure signal input; but gas/air ratio controls which change the air pressure in response to the gas pressure are not excluded. It is not applicable to mechanically linked valves and electronic systems.
