Abstract

The invention discloses a manually-operated louver valve, which comprises a flange, a casing, rotation shafts, hollow shafts, blades, a high temperature wear resistant rubber, cranks, a connecting rod, and handles, wherein the flange is connected with the casing; the rotation shafts are placed in the casing; the blades are fixedly connected with the hollow shafts; the rotation shafts are sleeved with the hollow shafts, and the two are in bolted connection; the high temperature wear resistant rubber is mounted at edges of the blades and the two are in bolted connection; the handles are connected with the external of the casing, and are connected with the rotation shafts through the cranks and the connecting rod. The valve can effectively control the blowing rate in various severe environments, effectively guarantees the sealing property particularly through the high temperature wear resistant rubber, can better control the leakage rate of the valve to a smallest level, and can allow exhaust gases to be better recycled and reused in a cogeneration.

Description

technical field [0001] The invention relates to a valve, in particular to a manual shutter valve. Background technique [0002] Manual and electric shutter valves have been widely used in cement, metallurgy, mining, etc. after a long period of development. [0003] At present, as far as the shutter valve is concerned, it is mainly used in pipelines, and the air volume can be well controlled through the shutter valve, but there are still defects in details, so there is still room for improvement. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a louver valve for controlling the air volume, which can achieve an air leakage rate of less than 0.1% by installing high-temperature wear-resistant rubber on the edge of the blade. Moreover, the shaft adopts a split structure, which is easy to replace the blades. [0005] The technical solution adopted in the present invention is: a manual shutte...
