blast valve

基本解释

Herein introduce the structural feature and operating principle of new-style cold blast snort valve of blast furnace.
介紹了高爐用新型冷風放風閥的結搆特點和工作原理。
Hot blast for cupola is realized by a new type hot blast valve instead of two valves in existent technology. The former type is easy to use and with simple construct.
此沖天爐熱風放散閥可替代現有技術需要兩個閥才能完成的熱風放散操作，結搆簡單，使用方便。
The results show that hot fatigue is the main factor leading to cracks so that the useful measures are advanced to provide theory basis for hot blast valve long life and equipments maintenance.
爲此，提出了防止熱疲勞的有傚措施，爲熱風閥長壽和設備維護提供了理論依據。
