Week 14 challenge
BUTTERFLY VALVE
Objective:
The objective of the project is to model butterfly valve an dapply gd&t in different parts and assembly of the butterfly valve.
Introduction:
Butterfly valve is quarter turn rotation motion valve, that is used to start, stop and regulate the flow, it is eeasy and fast to open A 90 degrees rotation handle is provided to complete the operation of butterfly valve where a hand wheel by a gear connected stem this simplifies the operation of valve but at the expense of speed.
Application of Butterfly valve:
- Cooling water, air, gases, fire protection, etc.
- Slurry and similar services
- Vacuum service
- High-pressure and high-temperature water and steam services
Advantages of Butterfly Valve:
Compact design used for considerbly less space compared to other valve
light in weight
quick operation requires less time to open or close
available in very large size
low pressure drop and high pressure recovery
Disadvantages of Butterfly Valve
- Throttling service is limited to low differential pressure
- Cavitation and choked flow are two potential concerns
- Disc movement is unguided and affected by flow turbulence
