The function of the vent hole
Thread Content
Some devices (on the top) are equipped with exhaust vents. What is the purpose of these exhaust vents? I understand its function to be: 1. To expel the gas inside the device in the case of a gaseous medium. 2. For liquid media, it serves to prevent the equipment from collapsing when emptied. Right? I’m seeking advice from everyone.
Because the pressure vessel is connected to the atmosphere
It’s the two functions you mentioned; here we often refer to them as vent ports, which are mainly used to release the gas inside the equipment. When filling with the medium, the equipment will not remain incomplete due to the presence of gas! !
It is mainly to remove the gas from inside the device, so that when the medium is filled in, the device will not remain incomplete due to the presence of gas. Those that are in communication with the atmosphere are usually called vent holes.
If the container contains a liquid, this liquid will produce certain gases at a specific temperature and pressure; over time, the internal pressure will increase. If there is no vent for releasing this gas, it can lead to dangerous situations! It’s purely my personal opinion!
There’s no need to worry about the liquid being pumped out and causing the container to become flat; it’s all about venting air. When filling with liquid, the top part is a dead zone, so it’s necessary to remove all the air from inside the device
The spherical tank seems to have no vent holes; then how does the air get out once the medium enters?
