AIM : The objective of this project is to design a butterfly valve and apply GD&T to it's components and final assembly using Siemens NX.

INTRODUCTION :

A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a shaft. When the valve is closed, the disc is turned so that it completely blocks off the passageway.When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle

Advantages of applying GD&T:

1. SAVE MONEY

2. Providing Accurate Communication

3. Ensuring Dimensional and Tolerance Requirements

COMPONENTS OF BUTTERFLY VALVE

1. BODY :Butterfly valves are usually fixed between two pipleines using flange couplings.

Body of our Butterfly valve and GD&T applied to the same using Siemens NX CAD are shown below.

2. DISC PLATE: When valve is fully opened or closed the disc is rotated a quarter turn.Disc is mounted on shaft. When the valve is closed, the disc is turned so that it completely blocks off the passageway.When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid.
