BUTTERFLY PROJECT

BUTTERFLY VALVE :

When the disc rotates half a turn, the throttle valve opens or closes fully. The throttle is a metal disc mounted on a rod. When the valve is fully open, the disc rotates half a turn, allowing fluid to flow freely. Rotate the disc another half turn to stop the fluid flow. There are many types of butterfly valves.
Each throttle valve has a different pressure and purpose. After modeling the various butterfly valve components, geometric dimensions and tolerances are applied to each component and final assembly.

PARTS OF BUTTERFLY VALVE :

1. BODY

Butterfly valves are secured between two pipelines using flanged couplings.

2. STEM

A disc, lever and nut are attached to the shaft.

DRAFTING

3. TOP FLANGE

This is a kind of washer that is fixed on the throttle body.

DRAFTING

4. DISC

To fully open or close the disc, turn it half (1/4) turn. The disc is mounted on the shaft. When the valve opens, the disc rotates and allows fluid to pass through. When you want to close, the disc spins and closes completely. Because the flow of fluid stops.

DRAFTING

5. LEVER

The lever is mounted on a shaft at the top of the shaft end outside the housing. A lever is used to control the rotation of the disc.

DRAFTING

6. NUT

It is secured to the top of the end of the shaft to hold the lever and top flange.

DRAFTING

7. SCREW

Screws are used to assemble the top flange and connect it to the body and shaft.

ASSEMBLY

After modeling the various components of the valve, all the parts were assembled together using the assembly bench in Catia v5 software.

CONCLUSION

The throttle has been successfully designed and Deometric dimensions and tolerances have been applied to all components and throttle assemblies.
