Embodiment Construction

[0011] A special valve for a blast furnace gas combined cycle power generation system, including a valve body 4, a valve seat 6, a sealing ring 8, a butterfly plate 7, a valve shaft 5 and a driving device 1, the valve seat 6 is fixed on the valve body 4, and the sealing ring 8 is fixed On the butterfly plate 7, the butterfly plate 7 is installed in the valve body 4 through the valve shaft 5, the angle between the plane of the valve seat 6 and the vertical surface of the valve body 4 is greater than or equal to 25 degrees, and the driving device 1 is a spring return type, including a cylinder 2 and spring 3. The full-open stroke of the valve is less than or equal to 65°, which creates conditions for quick cut-off from the source and reduces the instantaneous speed and impact force. The plane where the valve seat 6 and the sealing ring 8 cooperate is conical. When the valve is closed, the guide cone of the sealing pair can eliminate the accumulated dust on the sealing surface to...

Abstract

The invention provides a special valve of a blast furnace gas combined cycle power generation system. The special valve comprises a valve body, a valve seat, a seal ring, a butterfly plate, a valve shaft and a driving device, wherein the valve seat is fixed on the valve body; the seal ring is fixed on the butterfly plate; the butterfly plate is arranged in the valve body through the valve shaft; the angle between the valve seat plane and the vertical plane of the valve body is equal to or more than 25 degrees; the driving device is in a spring reset type structure and comprises a cylinder body and a spring; and the fit plane of the valve seat and the seal ring is tapered. The invention has the following beneficial effects: the valve action stroke is less than 25 degrees, the spring reset type driving device is adopted and the valve can be closed fast.

Description

technical field [0001] The invention relates to a valve device, especially a valve used in a blast furnace gas combined cycle power generation system. Background technique [0002] Blast furnace gas combined cycle power generation (CCPP) system is the most advanced comprehensive utilization technology of blast furnace gas. Its main function is to recycle blast furnace gas for power generation. Compared with conventional combustion gas boilers, the CCPP combined cycle system has higher power generation efficiency and can further utilize waste heat to maximize the utilization of remaining blast furnace resources. It is a key project to further reduce environmental pollution, realize clean production, and develop circular economy. At present, the valves used in the domestic blast furnace gas combined cycle power generation system take a long time to operate and cannot meet the requirements of fast shutdown of the system. Although the imported equipment can meet the requirements...
