Do irrigation valve cause water hammer?
Any quick closing valve such as a solenoid can cause hydraulic shock waves
How does quick closing valve work?
Quick closing valve is a kind of pressure reducing valve in which the an automatic process control valve for fluid pressure control is used for unmanned machinery spaces. This can be done by careful selection of valve trim, i.e. the parts of the valve that come in contact with the controlled fluid and form an actual control portion. The difference between pressure release valve and quick closing valve is that the later does not come in direct contact with the fluid it is controlling. The lever is connected externally to a remote operating mechanism which might be pneumatic or hydraulic controlled. The controlling system has a piston which moves with the pressure of air or fluid and simultaneously moves the lever attached to it. The lever at the other end is connected externally to the spindle which is attached internally to the valve.The valve is a spring loaded valve which means that the spindle is placed through a spring which helps in re-positioning of the valve to the open position when the air or fluid pressure in controlling cylinder reduces. All the quick closing valves are generally set in the open position.When the piston of the controlling cylinder moves up, the end of the lever which is connected to the piston moves up. As the lever is pivoted at the center, the other end of the lever moves down and pushes the spindle downwards. This closes the valve and shuts the flow of the fluid.
What valve assists the diaphragm in closing?
The Illeocecal valve
What is the difference between a ball valve and a globe valve?
A globe is designed for throttling and NON quick closing thus no hydraulic waves are caused. A ball type uses a ball normally stainless rather then a washer for a positive shut off
What can be an indication that a valve in the heart is not closing properly?
what
What is the name for an hcr valve?
High Closing Ratio
How does a idle air control valve work?
An idle air control valve controls the engine idle revolutions by opening/closing to let more/less air into the throttle body (carburetor)-the car computer reads and controls the valve.
What is muscular valve?
A muscular valve is like a strong flap that is capable of opening and closing at will. An example of a muscular valve is the pyloric sphincter.
The onset of ventricular contraction will result in what?
The mitral valve closing
When your heart pounds what is making the sound come from your heart?
The sound coming from your heart is the sound of the valves in the heart closing and the turbulence in the blood that results. In a normal healthy adult the first sound (or lub) is from the closing of the AV valve and the second sound (or dub) is from the closing of the semilunar valve.
What does IVC mean in relation to valve timing?
IVC is Intake Valve Closing, is the crank degrees when the intake valve is closed, after TDC(top dead center).
