    Line Steam Valve
AI Thread Summary
In steam line connections, globe valves are commonly used for throttling and flow control, while gate valves are typically specified for isolation purposes when the valve is normally open. Gate valves are more cost-effective but are not suitable for throttling due to poor flow control and potential damage to the discs. Throttling a gate valve can lead to leakage when closed, making it less reliable for regulating steam flow. Therefore, the choice of valve depends on the intended use: globe valves for control and gate valves for maintenance isolation. Proper valve selection is crucial for efficient steam line operation.

hi guys...can anyone tell me that whether v use only globe valve in steamline connections in common practice?
 
Engineering news on Phys.org
If the valve is normally open, and closed only to isolate the line for maintenance then a gate valve would be specified (lower cost). If the valve is throttled to control flow a globe valve is specified. Throttling a gate valve offers poor flow control and quickly wrecks the discs so the valve will leak by when closed.

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
