What is the correct English term for a breathing valve? Is \"conservation vent\" accurate? This post was last edited by niulijun117 on 2009-2-16 16:12.]
Pressure vent valves – that’s what it should be, right?
It should be respiration
pressure and vacuum safety valve
Based on the last API translation campaign. The breathing valve should be a PV valve, that is, a Pressure/vacuum vent valve. There is both inhalation and exhalation, so it should be a pressure/vacuum relief valve.
Haven’t you all heard of the term “repiration valve”? Although they mean the same thing, and its pronunciation is also similar to that of “conservation”; perhaps the original poster still has some lingering impression from having heard someone use “repiration valve”.
There are various translations in dictionaries: breath valve, breather valve (the most common term), breathing valve, resperation valve – any of these should work. I remember encountering the term PV valve in previous translation discussions; I don’t know in which post it was discussed, but I couldn’t find it.
That’s right, but I guess what the original poster heard was a respiration valve.
Conservation vent – translated in Chinese as safety ventilation valve; in its original English meaning, it refers to a protection valve that prevents the tank from reaching excessive pressure or vacuum levels, and also stops the internal medium from evaporating and being lost in large quantities. It is also known as a breathing valve; terms such as breather valve and respiration valve are commonly used. The difference between these terms is not clear
Conservation vent! I learned about that term too!
It’s what I saw in the dictionary, but the information in dictionaries usually doesn’t seem very accurate! !
This issue hasn’t actually been resolved; what was said on the 7th floor makes some sense. Correct answer: Breathing Valve. Other terms like PV or VENT are not breathing valves.
too conclusive!
It should be a pressure/vacuum relief valve; this is the usage in the United States.
I protested to the moderator regarding my comment; this wording in English is exactly as it appears in the product description for breath valves in the United States – how could it be wrong? I specialize in importing these breathing valves, and I have their English product documentation available. Additionally, the safety valve should be called a pressure safety valve
4.4.1.2 PV valves are recommended for use on atmospheric storage tanks in which petroleum or petroleum products with a flash point below 100°F (37.8°C) are stored, as well as on tanks containing petroleum or petroleum products whose fluid temperature may exceed the flash point. A flame arrester is not considered necessary when using a PV valve for venting to the atmosphere, since the speed of flames is lower than the speed of vapors moving across the seats of PV valves (see API Publication 2210).
The one installed on the storage tank is called a conservation vent; it provides two-way protection – when the pressure inside the tank exceeds a certain positive level, the exhaust valve activates to release the excess pressure, which is what the ‘P’ in PV refers to； When the pressure inside the tank falls below the set negative pressure, the suction valve activates to draw in air, preventing the tank from being crushed due to excessive vacuum – which is what the V in PV (Vacuum) refers to. It is often used in conjunction with flame arrestors for tanks. http://bbs.hcbbs.com/attachment.php?aid=Nzc1MTg3fGI3ZDMzZTYwfDEzMDgzOTgzNTZ8OWVjYVZLNW90WDY2OWxhSmRuczByMXJGL2dvOFZpbklBTmw2QkZPelJuQkhvMDQ%3D&noupdate=yes The one installed on top of the gearbox is called a breather, and it contains a filter element.
It should be the exhaust valve
