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.
