Spirax Sarco exhaust valve Steam system with automatic exhaust valve  Air and other non-condensable gases in the steam system will cause a lot of problems . Warm-up time will be extended only , and the mixture of steam and air at the same pressure will be lower than that of pure steam temperature . Air film reduces heat transfer efficiency , resulting in increased fuel consumption , and these gases are also the main reason for the air pipe corrosion formation . Use automatic exhaust valve Spirax Sarco steam system to exclude air and other non-condensable gases , while not leaking steam.  AV13 - using brass body , threaded connections, the working pressure 13barg, corrosion-resistant and built-in filter .  AVC32 and AVS32 steel and stainless steel were used . Threaded , flanged and welding connections , corrosion and built-in filter .  Water supply pipeline with automatic air eliminator  Air and other non-condensable gas inside the water pipe will cause a lot of problems , such as noise , corrosion, hysteresis loop , and even cause a temporary interruption of the device. When these gases are introduced into the water filling pipe , thorough and effective way to effectively eliminate the use of these gases automatic air eliminator .  Spirax Sarco air eliminator use the float buoyancy action. Air exclusion is a natural gathering place installed in the air exclusion can automatically turn on to exclude air and automatically shut down when the water passes through . Air exclusion is automatic work , either in the boot or runtime are no adjustment . Air vent for the following applications :     Automatically exclude air     S emptying liquid systems     Steam system to exclude air Avoid residual air system , or waste steam   斯派莎克AV13?*��?/strong>蒸汽系統用自動?*��?  空氣及其它不凝性氣體在蒸汽系統中會引起很多問題。不但會延長暖機時間，而且在相同壓力下蒸汽及空氣混合物會比純蒸汽溫度低。空氣會形成氣膜降低傳熱效率，從而導致燃料耗量增加，并且這些氣體也是管道腐蝕的主要原因。使用斯派莎克的自動?*�阀可排除蒸汽系统中的空气及茰O�不凝性气体，同瘦厯Q嶁孤┱羝��? 斯派莎克AV13?*��?/strong> - 采用黃銅制閥體，螺紋連接，工作壓力13barg，耐腐蝕并內置過濾器。  AVC32和AVS32分別采用鋼結構和不銹鋼結構。螺紋，法蘭和焊接等連接方式，耐腐蝕并內置過濾器。 斯派莎克AV13?*��?/strong>給水管道用自動空氣排除器  給水管道內的空氣及其它不凝性氣體會引起很多問題，如噪音、腐蝕、循環遲滯，甚至造成設備的暫時中斷。這些氣體是在管道充水時引入的，徹底而有效地排除這些氣體的有效方法是使用自動空氣排除器。  斯派莎克AV13排空氣閥利用浮球的浮力動作。空氣排除器安裝在空氣自然聚集處，排除器能夠自動開啟以排除空氣，并在水通過時自動關閉。空氣排除器是自動工作，無論在開機或運行時均無需調節http://www.spiraxsarcocn.com/Product/37.html。
