Round door is also known as round bezel door, round closed door, round adjustment door. Round wind door is mainly used in power plant ducts, flues to intercept or adjust media flow, but also can be used in other industries of ducts, flues. The round door allows all circulation/truncation of a line medium in the system or the flow of the media varies with control. For the small diameter of the round door, it has two functions of intercepting and regulating the flow of the media, for the large diameter of the round door, its adjustment function is not obvious, the main application of its cut-off function.
According to the performance can be divided into round closed door and round adjustment door, according to the driving method can be divided into manual round door, electric round door and pneumatic round door, according to the manufacturing process can be divided into casting round door and welded round door, according to the material can be divided into cast iron round door, carbon steel round door and stainless steel round door. In addition, our company also developed a multi-blade single-stop round door, multi-blade double-stop wind door, as well as dedicated to the flue gas desulfurization system entrance, exit and bypass of the circular flue bezel door (flue bezel door).
The typical round door is a butterfly valve-type single-plate structure, its front and rear shaft neck in the form of internal support outer seal, support is a sliding bush structure, this structure is widely used in small units and low requirements of the occasion. In order to adapt to the growing number of 600MW, 900MW or even 1000MW units at home and abroad, our company in 74DD standard on the basis of a large number of specifications expansion and structural optimization work, developed a series of high-performance new round door, the current maximum diameter can be done to DN8000. The front and rear shaft neck of the new round door adopts the structure of the inner sealed external support, the special seal ingress sinist is well sealed, no leakage, high temperature, and the support point uses self-lubricating automatic centering bearing, which can automatically compensate the same axial deviation of the front and rear axles, ensuring that the round door resistance is small, no card, flexible rotation. The executive mechanism of the new round door can be installed directly on the wind door body, without the need for a crank linkage mechanism. For multi-blade single-stop round door, multi-blade double-stop wind door, as well as special for the inlet of the flue gas desulfurization system, exit and bypass of the circular flue gas bezel door (flue bezel door) structural features see closed bezel door, adjustment bezel door introduction.
