The tension of water resources and the deteriorating, has been an urgent problem that global, so water saving, energy saving has become the international general trends. In terms of blast furnace equipment, the conventional hot blast valve cooling water use, energy consumption, become the key to saving energy and reducing consumption of blast furnace.

Henan Shangfa Valve Co., Ltd, actively tracking the latest technology of blast furnace equipment, insist for a long time to high-tech products research and development, and iron and steel equipment research institutions and enterprise cooperation developed micro water hot blast valve. Through the new design, greatly reduce the hot air valve of cooling water, and to reduce heat loss, be the first choice of the blast furnace energy saving key equipment.

Use high temperature resistant, intermediate refractory low;
Low cooling water channel specially designed to ensure that the best cooling effect;
Low cooling water the province;
Through the multilayer insulation, production process temperature loss minimum;
Low year-on-year increase blast temperature around 10 oc;
Because to reduce heat loss and reduce cooling water, make valve operation cost is reduced;
Low and the application of conventional liner of the hot blast valve four mature technology;
(full cover not finalize the ceramic refractory, the asymmetric water cavity structure, the valve plate composite material protection, stem the floating sealing device)
Low a variety of transmission methods (electric, hydraulic, pneumatic, manual, etc.).

Low air temperature: 1350 ℃ ~ 1650 ℃
Low air pressure: 0.4 ~ 0.6 Mpa
Low water: 30 to 40% of the conventional hot blast valve with specifications
Low pressure: 0.4 ~ 0.7 Mpa
Low can bear larger thermal shock and thermal fluctuations
Low compared to the conventional hot blast valve life extension 2 ~ 3 years
Low maintenance is simple and convenient maintenance

Blast furnace hot blast valve, valve and the backflow damping down valve, and interchangeable with the original conventional hot air valve.
