一、热水采暖系统排除空气的意义热水采暖系统中空气是最有害的因素。当管道中有空气积存时,往往要影响热水的正常循环,造成某些部分不热;空气中含有氧气是造成金属腐蚀的主要原因,所以必须重视排除空气的问题。热水采暖系统排除空气的情况有三种: 第一,是系统充水阶段。整个系统原是空的,充满了空气。当冷水由系统下部充入系统时,空气逐渐被水挤出。在充水时系统的各最高点的排气阀都要打开,当排气阀因水充满而溢水时就关闭;当系统完全充满水时,充水管也要关闭,这样系统被隔绝。只
First, the significance of hot air heating system to exclude air Hot air heating system is the most harmful factor in the heating system. When there is air accumulation in the pipeline, it often affects the normal circulation of hot water and causes some parts to be non-heating. Oxygen in the air is the main cause of metal corrosion, so we must pay attention to the problem of eliminating air. There are three situations in which the hot water heating system eliminates air: First, it is the water filling stage of the system. The entire system was empty and full of air. When the cold water is charged into the system from the lower part of the system, the air is gradually squeezed out of the water. When the water is filled, the exhaust valve of the highest point of the system must be opened. When the exhaust valve overflows with water, the exhaust valve closes. When the system is completely filled with water, the water filling pipe is also closed, so that the system is isolated. only
