Embodiment

[0026] Such as Figure 1 to Figure 3 As shown, the present invention provides a precise control manual shutter valve, including: a shutter valve body, a control device, and a display assembly. The shutter valve body includes: a base 1, a valve body 2, a valve stem 3, a valve plate 4, and a valve body 2. It is fixedly connected to the base 1. There are several valve stems 3 and they are rotatably assembled on the valve body 2. The valve plate 4 is fixedly connected to the valve stem 3 and adapted to the valve body 2. The valve stem 3 is vertically They are arranged at even intervals, and both ends extend to the outside of the valve body 2 .

[0027] The control device is located on the base 1, and the control device includes: a mounting plate 5, a fixed shaft 6, a runner 7, a wrench 8, a limit assembly, and a transmission assembly. The mounting plate 5 is fixedly connected to the base 1, and the fixed shaft 6 is fixed Connected to the side wall of the mounting plate 5, the run...

Abstract

The invention relates to a precisely-controlled manual louver valve. The precisely-controlled manual louver valve comprises a louver valve body, a control device and a display module. The louver valvebody comprises a base, a valve body, valve rods and a valve plate. The control device comprises a mounting plate, a fixing shaft, a rotation wheel, a wrench, a limit assembly and a transmission assembly. The display module comprises a rotation disc and a vertical rod. The rotation disc abuts against and is in contact and meshing transmission with the outer wall of the rotation wheel, and the rotation disc is provided with a dial. According to the precisely-controlled manual louver valve, the wrench drives the rotation wheel to rotate, the transmission assembly drives the valve rods to rotate,so as to rotate the valve plate, when the rotation wheel rotates, the dial is driven to rotate, the vertical rod is relatively located above the dial, and the angle of rotation of the rotation wheelcan be visually observed, so that the angle of the rotation of the valve plate is conveniently precisely adjusted. After adjustment is completed, the limit assembly limits rotation of the rotation wheel, and the stability of the louver valve during work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shutter valves, in particular to a precisely controlled manual shutter valve. Background technique [0002] At present, the louver valve is mainly used in pipelines, and the air volume can be well controlled through the louver valve. The existing louver valve has been widely used in cement, metallurgy, mining and other industrial occasions after the development of time, and its appearance has solved the need to open and close and effectively control the air volume when each pipeline is ventilated. However, the rotation and opening angle of the leaf plate of the existing manual shutter valve cannot be adjusted accurately, which affects the ventilation efficiency of the valve. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a precisely controlled manual shutter valve, which has the advantage of precisely adjusting the rotation and opening ...
