Week 14 challenge

Assemble and apply GD&T to the butterfly valve assembly drawing

About Butterfly Valve:

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 rod. 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 flow.

There are different kinds of butterfly valves, each adapted for different pressures and different usage. The zero-offset butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high-performance double offset butterfly valve, used in slightly higher-pressure systems, is offset from the center line of the disc seat and body seal (offset one), and the center line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve. In this valve, the disc seat contact axis is offset, which acts to virtually eliminate sliding contact between disc and seat. In the case of triple offset valves the seat is made of metal so that it can be machined such as to achieve a bubble-tight shut-off when in contact with the disc.

The parts of Butterfly Valve:

• Body
• Shaft
• Retainer
• Disc Plate
• Lever handle
• Nut
• Screw

In the given challenge they have not given the screw i have created the Screw cadd and assembled in Butterfly Valve.

These are the parts of the Butterfly Valve assemble Our task is to assemble them in the Cad using this Parts. Using the Move and Assembly commands assembled all the parts keep the 6 DOF in mind Created Assembly of Butterfly Valve
