VALVE

Valve comes from the Latin word valvŭla , which is the diminutive of the term valve (that is, “door” ). A valve is the device that allows the regulation or control of a certain flow of gases , liquids or other substances.

Through a valve, it is possible to allow or interrupt the passage of something thanks to a part that moves to release or block a conduit. The industrial valves are those that are used in machines , such as a gate valve one valve seat or valve , among others.

Within the industrial field we have to state that the so-called ball valves play a fundamental role. These have a long list of advantages and relevant identity signs that have made them a benchmark. These are the following:
-They are very easy to open and close, since all you have to do is move the handle that they have about 90 degrees in one direction or the other.
-They offer long durability.
-They dramatically decrease the risk of a leak occurring.

However, there are also the so-called globe valves. These are usually found in a very common way in what are flow controls, they are shaped like an "S" and have the particularity that they allow a greater pressure drop than in other types of valves.

A safety valve is one that acts if a fluid exceeds the pressure level considered adequate, preventing the system from exploding due to excessive pressure. The purpose of these valves, therefore, is to relieve pressure .

In the context of anatomy , a valve is the fold of a membrane that prevents the fluids circulating through the body's vessels from backing up. The heart valves , in this framework, allow blood not to flow in the opposite direction when it leaves the heart.

These valves cause blood to be retained momentarily in a chamber of the heart and then, through contractions of the organ, to be pumped where it belongs. If the heart valves were not present, each contraction would cause the blood to return through the same tube and the irrigation of the whole organism could not be achieved.

The heart has four valves: the pulmonary valve , the aortic sigmoid valve , the tricuspid valve, and the bicuspid valve . Disturbances in the operation of the valves known as valvular.

In addition to all the above, we cannot forget that the word in question is also used colloquially with another meaning. We are referring to the expression escape valve that is used to refer to those “tools” or resources that a person has to be able to release the stress, worry or anguish that plagues them.

In this way, for example, we find that there are individuals whose escape valve they have to forget about their problems or the tension they accumulate, for example, with work is cycling, climbing, fishing, hiking, music or practicing any group activity you like.
