The Design of Rotary Cylinder in the Water Treatment System
Abstract: The rotary cylinder is an important part of the system of water treatment; it usually needs the butterfly valve which is controlled by the rotary cylinder to separate the water in different moment. The rotary cylinder, which is used to control the open and close of the butterfly valve, is becoming more and more widely used in the advantage of its compressed air driven power, convenient resource, quick response, remote control and automatic operation, simple construct, easy maintenance, low cost.
The issue of this graduation design is the design of rotary cylinder in the water treatment. Through comparing the control ways of butterfly valves, rotary cylinders are selected as the equipment to control butterfly valves, and the working principle of the rotary cylinder is introduced. Then verifying the design project of the structure of rotary cylinders, and then designing the structure of the components in the rotary cylinder, calculating and checking the main parts of the rotary cylinder. Last, with the knowledge of drawing, the assembly drawing and the main parts of the rotary cylinder are done.
Key Words: water treatment, butterfly valve, rotary cylinder
