Week 14 challenge

BUTTERFLY VLAVE

Assemble all the components in assembly workbench

ASSEMBLY CONSTRAINTS:

Assemble all the components in assembly workbench

2D_DRAFTING & GD & T

HERE IAM IMPLEMENTING THE GD &T TO THE BUTTERFLY VALVE NOT TO THE ASSEMBLY BECAUSE IT IS SAME TO GIVING GD&T TO THE ASSEMBLY

AS THE APPLICATION ASPECTS VALVE MATING SURFACE SHOULD HAVE SMOOTH SURFACE, IF IT HAS SOME UP AND DOWN THEN IT CREATES THE FITMENT ISSUES AND AS WELL AS LEKAGE WHILE COUPLING THE VALVE,SO HERE WE NEED ALL MATING SURFACE SHOULD HAVE FLATNESS TOLLRENCE VALUE OF 0.25.

ALL THE HATCHED SECTION ARE THE MAINTAINED WITH THE FLATNES TOLLRENCE

DATUM'S:

DATUMS AS USED DEPENDING UP ON FEATURE OF SIZE AND APPLICATION, APPLICATION OF DATUMS IS ARREST DEGRES OF FREEDOM OF THE PART AND DEFINING LOCATION.

DATUM ARE THREE TYPES

• PRIMARY DATUM-(ARREST 3 DOF)
• SECONDARY DATUM-(ARREST 2 DOF)
• TERTIARY DATUM-(ARREST 1 DOF)

PRIMARY DATUM

SECONDARY DATUM

TERTIARY DATUM:

HERE WE USING MORE THEN 3 DATUMS BECAUSE WE NEE THE CONECTING POINTS SHOULD BE COLINEAR WITH OPSITE SIDE CONNECTING POINTS

FEATURE CONTROLE FRAME:

FFF OF HANDLE:

IN THIS I USING FLATNES,PISITION,PERPENDICULAR,CYLINDRICITY AS WE REQUIRED

BASIC DIMENSION:

BASIC DIMENSIONS ARE USED ONLY FOR 2 HOLES PITCH DIMENSION,HEARE WE DONT ALLOWED TO GIVE THE TOLERENCE VALUE

CONSTRAINED ALL OTHER DIMENSIONS WITH REQUIRED TOLLERENCE VALUE:
