Abstract

The invention discloses a manually-controlled shutter valve. The valve comprises a flange, a valve body, a valve plate, a valve shaft, the manual driving mechanism and a control assembly, wherein theflange is connected with the valve body, a plurality of stepped holes are symmetrically formed in two side plates of the valve body, and each stepped hole is internally provided with a sleeve, the twoends of the valve plate are both provided with holes, the valve shaft comprises a right valve shaft and a left valve shaft, and the left valve shaft and the right valve shaft are both stepped shafts,the two ends of the plurality of valve plates are respectively connected with the right valve shaft and the left valve shaft, and is arranged on the inner side of the valve body in parallel through the stepped holes in the two side plates of the valve body in the vertical direction, the manual driving mechanism comprises a crank, a connecting rod and a large hand wheel, one end of the crank is fixedly connected with the corresponding left valve shaft, the other end is hinged to the connecting rod, the large hand wheel is connected with any left valve shaft, the left valve shaft can be drivento rotate through the rotation of the large hand wheel, the control assembly is connected with the other left valve shaft and is used for controlling the opening degree of the shutter valve. The valveis simple in structure, easy to operate, high in stability and sealing performance and convenient to maintain in long-term operation.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a manually controlled louver valve. Background technique [0002] Shutter valve is a new type of regulating valve, which is mainly used for the regulation and opening and closing control of air, flue gas and other gases in process pipelines, and is widely used in metallurgy, chemical industry and other fields. The shutter valve is mainly composed of valve body, shutter, shaft and control mechanism, and can be used with various actuators for different occasions. [0003] At present, the electrically regulated louver valve uses an electric actuator and a reducer to adjust the opening of the valve. The overall actuator is complex and inconvenient to operate. At the same time, in long-term use, due to wear and corrosion, the stability of the transmission mechanism will be extremely high. If the ground drops, there will be problems such as unreliable valve sealing. The manual control...
