Week 14 challenge
Assemble and apply GD&T to the butterfly valve assembly drawing
Butterfly valve: working principle
The construction of a butterfly valve is relatively simple, with the rotation of the valve disc controlling the fluid flow. In the closed position, the disc blocks the valve bore while in the open position, the disc is oriented perpendicular to the flow direction to allow flow.
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.
A butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc. A rod feeds through the center of a disc and this rod is connected to an actuator that controls the motion of the disc.
Applications of Butterfly Valves
The main applications of these types of valves are in the pharmaceutical, chemical and food industry or in the water flow control in dams and hydroelectric power plants. In the latter two applications, butterfly valves are either used with a control function or a protection function.

This is 3D Assemblying Model.
In this Assemblying Model We haqve Six Component.
Stem/Shaft
Nut
Lever
Top Flamge
Disc
Body
Body
For Assemblying for this six component we used Assemble feature, Like Move component And Assembly Constraints.




This is 2d drawing.
In this 2d drawin we gave gd&t Symbol and Tolerance
