Discussion Overview

The discussion centers on the principles and operation of mechanical valves, specifically heart valves and reed valves. Participants explore the physical principles that govern their functionality, particularly focusing on how these valves allow fluid flow in one direction and prevent backflow.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant seeks detailed information on the physical principles behind the operation of heart and reed valves.
  • Several participants clarify the types of valves being discussed, with a focus on mechanical valves.
  • It is noted that heart valves function similarly to a "duckbill" valve, which allows flow in one direction.
  • Another participant describes the mechanism of a valve as a "trap-door" that can be pushed open from one side but not the other, explaining the prevention of backflow.
  • A reference to check valves is made, indicating a related concept in plumbing.

Areas of Agreement / Disagreement

Participants generally agree on the basic operational principles of the valves discussed, but there is no consensus on the depth of explanation or specific physical principles involved.

Contextual Notes

The discussion lacks detailed exploration of the underlying physics and mechanics of the valves, and assumptions about the audience's prior knowledge are not explicitly stated.

Who May Find This Useful

Individuals interested in mechanical engineering, biology (specifically cardiovascular physiology), or fluid dynamics may find this discussion relevant.

Hello to everybody!

I would like to find out how valves work but I can`t find detailed information through Google.
Could you tell me on what physical principles their work is based on? Most of all, I`m interested in heart valves or their analogs - reed valves. Thank you in advance.
 
Physics news on Phys.org
Valves? Lots of different kinds of valves, do you mean vacuum tubes or solenoids? Or what?
 
Do you mean energy conversions like headloss or do you want mechanical construction? What kind of valves?
 
I mean mechanical valves, especially, reed valves or heart valves. Why do they work so that the liquid or gas flow only in one direction? What prevents the backflow of liquid?
 
If you look at a picture of a heart valve, it's pretty self-explanatory.

Heart valves are pretty simple, similar in concept to a "duckbill" valve.

Samwell it's just a trap-door.

You can easily push it open from one side,
but you can't do the same from the other side.

i.e. It only pushes open from one side.
 
Thank you very much guys for explanation!
