Energy-Saving Hot Blast Valve
The Energy-saving hot blast valve is designed for the isolation of stoves from the hot blast main in the blast furnace complex. It can also be used for the isolation of hot gases in other industries.
The valve mainly consists of a body, bonnet, water cooling jackets, floating gate, counterweight (optional), and drive mechanism. In order to permit the flow of the hot blast from the stove to the furnace, the Energy-saving hot blast valve is opened with the help of a drive mechanism. When the valve closes, the back pressure from the blast furnace seals the floating disc of the Energy-saving hot blast valve against the body seat. Specially designed cooling jackets ensure constant cooling of the valve body while reducing heat loss to cooling water, making the valve energy efficient. Refractory lining is provided to minimize heat loss to cooling water and protect critical parts from blasts of hot air. The stuffing box ensures leak tightness and maintains the floating gate feature of the valve.
