CREATION OF BUTTERFLY VALVE AND APPLY GD&t

AIM: The main moto of this project is to design the assembly of the Butterfly valve and apply the GD&T concepts to the various parts of the Butterfly Valve.

SOFTWARE USED: CATIA V5

INTRODUCTION:

BUTTERFLY VALVE :

A Butterfly valve is a quarter-turn rotational motion valve, that is used to stop, regulate, and start a flow. Butterfly valves are easy and fast to open.

Applications of Butterfly Valve :

• Compressed Air or Gas Applications
• Cooling water, air, gases and fire protection
• Slurry and similar services
• Vacuum service etc..

COMPONENTS OF BUTTERFLY VALVE :

1] BODY :

2]SHAFT :

3] RETAINER:

4] PLATE :

5] HANDLE :

6] NUT :

ASSEMBLY :

Above Used GD&T Symbols and their Meanings:

Symbols	Characteristic	Description
	Position	Locate the center point axes.
	Straightness	is applied to a single line in which irregularities should be wih in two parallel straight lines.
	Flatness	It is applied to surface, Hence the irregularities in surface should be within the limits of a two parallel lines
	Circularity	It is applied to only single cross section
	Cylindricity	Applied to surface of the cylinder, the dia of the cylinder should be lie within the concentric cylinder.
	Profile of a Surface	Measurement of line across of surface irregularities on straight ine surface
	Perpendiculariy	Orientation of surface axis should be perpendicular to datum reference
	Angularity	Control the angle of feature.
	Parallelism	Orientation of surface axes should be parrallel to datum reference.
	Concentricity	Meadian point for the given feature.
	Symmetr	Similar to the concentricity but applied to rectangular feature .

CONCLUSION:

The Butterfly valve is successfully created and GD&T is applied to all the different parts and the assembly of the Butterfly valve.
