郾城冶金设备配件厂为云南省牛场铁厂100m~5高炉设计的通径φ500mm的新型热风阀,经过三年半的运行试验,证明该阀基本上保证了在风温1150℃工作情况下的正常使用,各种技术指标均达到了设计要求。目前该厂正在拟定产品的制造标准,并准备在100m~3左右的中小型高炉上推广应用。 这种新型热风阀的阀体内部是无内水圈式的大空腔,在阀体下端有4根进水口管,上端有4根出水口管,管径均为G1 (1/2)。冷却水以0.15MPa的压力经进水口管进入阀体的大空腔内,便全方位迅 Baocheng Metallurgical Equipment Parts Factory is a new type hot-blast valve with a diameter of φ500mm which is designed for 100m ~ 5 blast furnace of Niuchang Ironworks in Yunnan Province. After three and a half years of running test, it proves that the valve basically ensures that when the air temperature is 1150 ℃ The normal use of various technical indicators have reached the design requirements. At present, the plant is preparing product manufacturing standards, and is ready to promote the use of small and medium-sized blast furnace of about 100m ~ 3. The new hot-air valve body inside the body is no water ring large cavity, the lower end of the valve body has four inlet pipe, the upper end of the four outlet pipe diameter are G1 (1/2). Cooling water to 0.15MPa pressure through the inlet pipe into the body of the large cavity, then a full range of fast
