湘钢炼铁厂于1982年12月在1号高炉热风炉上安装了一台新热风阀。此阀是秦皇岛冶金机修厂根据该厂提出的一些技术要求进行设计制作的。现在新阀已使用7个多月,未发现漏风现象,与原来的旧阀相比,热损失也大大减少。新阀结构上的特点是:阀体内部取消了水圈(冷却器),阀壳水冷的水流通道也作了较合理的布置。冷却水从壳体上部进入,
In December 1982, the Xiangtan Ironworks installed a new hot blast valve on the No. 1 blast furnace. This valve is Qinhuangdao Metallurgical Machinery Plant under the factory made some technical requirements for design and production. Now the new valve has been using more than seven months, did not find the phenomenon of air leakage, compared with the original old valve, the heat loss is greatly reduced. The new valve structure is characterized by: the elimination of the body inside the hydrosphere (cooler), the valve shell water-cooled water flow channel also made a more reasonable arrangement. Cooling water from the upper part of the shell into,
