Butterfly valve Assembly

Assembling the components -

• Create a new assembly file in the same folder components are created.
• Insert all the components in the assembly and make the body component fix to constrain all the parts.
• Using move and constrain tools to assemble the component.
• Hole and pin constrain all the axis or center line of the parts.
• Using touch option fixed the surface touch each other with required function.

Drafting for Assembly -

• In application move to modelling to drafting and select the required sheet for Assemble.
• Using base view tool to insert 2D image of assemble and project all the view needs to explain.
• In butterfly valve function of the valve is pipes were connected to side of the valve
  so, need give dimension and GD&T to ear holes of two sides.
• Give flatness Tolerance to ear holes outer surface as primary datum to pipes connected with valve by nuts and bolt.
• Circular datum targets are in the surrounded region of the hole.
• Secondary datum B as giving perpendicular tolerance to the next ear hole with respect to A.
• Teritary datum C to control the position tolerance with respect to A & B.
• Profile Tolerance are given to control Width or thickness of body with respect to three datum.
• Position tolerances are provided to opposite ear holes from flatness tolerance as co axial holes control the position of ear holes.
