Abstract

The invention relates to a novel high-temperature bleed valve, and belongs to the technical field of bleed valves. The bleed valve comprises a valve body, a valve seat assembled at the upper end of the valve body, and a valve cover used for sealing an opening in the upper end of the valve seat, and the upper end of the valve cover is hinged to a valve cover bracket through a connecting rod; an opening and closing control device is arranged on one side of the valve body; the opening and closing control device comprises a supporting frame, a spring cylinder hinged on the supporting frame and used for sealing the valve cover, a hydraulic cylinder fixedly arranged on the supporting frame and used for opening and closing the valve cover, and a connecting rod mechanism used for transmitting acting force; the connecting rod mechanism comprises a rotating shaft hinged to the supporting frame, a connecting frame fixed to the valve cover, and a pull rod; one end of the pull rod is hinged with the lower end of the connecting frame, and the other end of the pull rod is fixedly connected with the rotating shaft; and a crank is further fixedly arranged on the rotating shaft, and the end of the crank is further hinged to the action ends of the hydraulic cylinder and the spring cylinder separately. The novel high-temperature bleed valve is high in applicable temperature, capable of automatic bleeding, hermetic, safe and reliable, and the effect of protecting a furnace top and a container can be achieved.

Description

technical field [0001] The invention relates to a novel high-temperature relief valve, which belongs to the technical field of relief valves. Background technique [0002] The practical furnace top gas release valve on the blast furnace is installed on the top release pipe of the ironmaking blast furnace to play the role of safe release. When the blast furnace is in normal production, it needs to maintain a constant pressure inside. When the pressure inside the blast furnace rises, the relief valve on the top of the furnace will automatically open to release the excess pressure to keep the pressure inside the blast furnace constant, thereby avoiding accidents caused by pressure fluctuations in the blast furnace. [0003] The pressure and temperature of similar products currently used are relatively low, generally between a few Kpa and tens of Kpa. However, this pressure range cannot well meet the actual use requirements. Contents of the invention [0004] The object of t...
