就小编而言，大多数人选择燃气锅炉来进行蒸汽，供暖，洗浴等。 对于燃气锅炉，认识的朋友必须知道系统气密性对锅炉本身的重要性。 在这个小系列文章中，我们山东燃气锅炉将介绍燃气锅炉对系统气密性的要求，并希望对大家有所帮助。
　　As far as Xiaobian is concerned, most people choose gas-fired boilers for steam, heating, bathing and so on. For gas-fired boilers, friends must know the importance of system gas tightness to the boilers themselves. In this small series of articles, we Shandong Gas Boiler will introduce the gas tightness requirements of the gas boiler system, and hope to help you.
　　燃气系统对于家用燃气锅炉，重要的是系统的气密性，以确保系统不泄漏，这取决于安装的质量和安装后的气密性测试。 安装完成后，关闭燃气锅炉燃气接口的阀门，打开燃气管道上的阀门，并用肥皂水涂抹接口以检查气密性是否良好。
　　For domestic gas boilers, the most important thing is the air tightness of the system to ensure that the system does not leak, which depends on the quality of installation and the air tightness test after installation. After installation, close the valve of the gas interface of the gas boiler, open the valve on the gas pipeline, and smear the interface with soapy water to check whether the air tightness is good.
　　另外，燃气系统应确保燃气锅炉额定功率工作时燃气锅炉前方的燃气压力为额定压力，具体取决于燃气管道系统的压力损失。 燃气管道系统的压力损失由两部分组成，由管道沿路径阻力引起的压力损失和由压力损失引起的局部压力（如弯头，减压器，三通，阀门，煤气表等）。 气体系统的压力损失与管道和管件的结构参数（管道直径，长度，粗糙度等）以及流量和气体参数有关。

　　In addition, the gas system should ensure that the gas pressure in front of the gas-fired boiler is rated when the rated power of the gas-fired boiler is working, depending on the pressure loss of the gas pipeline system. Pressure loss of gas pipeline system consists of two parts, which are pressure loss caused by resistance along pipeline path and local pressure caused by pressure loss (such as elbow, pressure reducer, tee, valve, gas meter, etc.). The pressure loss of gas system is related to the structural parameters (pipe diameter, length, roughness, etc.) of pipes and fittings, as well as the flow rate and gas parameters.
