Grp27: Release Valve
Material: Brass and Plastic
Manufacturing Process: Machined on a lathe then threaded using a screw machine. Flats were milled.
Function: If there is a build up, or if the pressure gets to much then plastic top will pop off release valve, thus reducing the pressure.
Is located on the side of the pneumatic system. Valve is held to the side by being screwed into the side of the system.
Brass was used because of its easy to manufacture. Plastics were used because of its ability to pop out with ease to relieve preasssure if needed.
Forces applied are some forces due to preassure, and forces pressing down on the threads when the release valve is tightened.
The magnitude of the preassure in the release valve usually would be around 50 psi. The thread force holding the valve tight into the pneumatic system is estimated at 8 lbs.
Each manufacturing processs was chosen for this compnent because it was the easiest, fastest, and chaeapest way to do it at high volumes of product.
The compnent is functional.
On a scale from 1-5, 1 being the simple like a ball, and 5 being complex like an engine, this component is a 2.5. This component is more complex than a wheel, but less complex than a watch. It is pretty basic, but the effect of the plastic top sensing when there's too much preassure and poping off makes it a littler more complex than just basic.
