Talk:Relief valve

Untitled
I did not understand the sentence about the spring under hydraulic relief valve. That is why I deleted it. Maybe the one who wrote is can make the addition more clear.

valve
What is the different between relief and safety valve? can you elborate more? —Preceding unsigned comment added by 85.154.251.26 (talk) 06:19, 13 November 2007 (UTC)

I would like to suggest the addition af area control and volume control in pressure measurement, keeping in mind relief valves and regulating valves. The coverage of those basics will make the subject matter more clear. — Preceding unsigned comment added by Shri chillies (talk • contribs) 06:49, 19 July 2011 (UTC)

Why I removed the image added by User:Shriram
The image has very little, if any, merit:


 * All it shows is an man looking at a piece of equipment. If not so stated in the caption, I would not have recognized that it was an "oil-immersed transformer".
 * I can see nothing in the image (even when enlarged) that looks like a relief valve).
 * Even if I could recognize a relief valve in the image, so what? What is notable about a man looking at a piece of equipment?

With all due respect, I don't believe the image provided any additional knowledge to this article. mbeychok (talk) 18:16, 31 July 2012 (UTC)

Description Too Specific
Relief valves are very general and are used with all sorts of liquids and gases. In the description of operation, the wording is very specific to venting of flammable gases, with reference to the relief path ending with a flare combustor. This is a very specific description for what is a much more general device. I would just remove the sentence portion refering to a flare, but am not sure if there is proper general terminology that should be used to describe the general relief path in lieu of flare combustion. 128.101.142.152 (talk) 15:30, 29 May 2015 (UTC)

"The diverted fluid (liquid, gas or liquid-gas mixture) is usually routed through a piping system known as a flare header or relief header to a central, elevated gas flare where it is usually burned and the resulting combustion gases are released to the atmosphere"

Agreed, this is far to specific. In many applications, the vent from a PSRV is a short length of pipe, set so that it does not fill with rain water (which can affect the lift pressure and also give rise to a hazard when ejected), in others (such as main steam relief valves on large steam turbines), the discharge pipework is routed via silencers and housed in large concrete blast bunkers to protect personel. — Preceding unsigned comment added by 192.149.117.67 (talk) 09:14, 5 December 2020 (UTC)
