Task

Model a flanged ball valve body with a square actuator mounting pad as a single solid part in millimetres, then produce a dimensioned drawing of it. Work from the supplied dimensioned diagrams: diagram_01.png and its detail views diagram_01_detail01.png to diagram_01_detail04.png.

Body and flanges:

The body is a horizontal flow passage with an end flange at each end.
The overall face-to-face length is 328 mm.
Between the flanges, the body is a double-tapered, barrel-like shell. Two conical halves meet at the mid-plane and blend into the flanges with small fillets.
Each end flange is a circular disc of Ø200 with a Ø196 diameter as dimensioned on the front view.
Each flange has six through bolt holes equally spaced on a bolt circle.
Each flange has a central bore through the flow passage.

Neck and actuator pad:

A cylindrical neck rises vertically from the top of the body to a square actuator mounting pad.
The pad is 200 mm square with R20 corner radii.
The pad has four through holes on a square pattern. On the top view these are located 84 mm from each flange face and 80 + 80 mm apart along the flow axis.
A central stem bore of Ø48 passes down through the pad and neck.
The stem bore has a Ø55 counterbore at the pad top face.

Vertical dimensions:

From the flow axis to the underside of the body: 100 mm.
From the flow axis to the neck reference: 80 mm.
From that reference to the top of the pad: 105 mm.
Total height: 285 mm.

The finished solid should measure approximately 200 × 328 × 285 mm overall.

Part file:

Save the model as FLANGED_VALVE_BODY.prt containing one solid body.

Drawing:

Create the drawing in FLANGED_VALVE_BODY_dwg1.prt on one sheet in third angle projection.
Show a top view, a front view, a side or section view and an isometric view. Hidden edges should be shown in the orthographic views.
Dimension the views, including R20 on the pad, the Ø55 counterbore, the Ø48 stem bore, the Ø200 flanges and the 200 pad width.
Include a title block with a title, a drawing number and the sheet number (1 OF 1).
State that dimensions are in millimetres.
