- Q:The atrioventricular valves will be open whenA. Atria are in diastole and ventricles are in systole B. Pressure in the ventricles is greater than the pressure in the great arteries C. The ventricles are being passively filled D. The ventricles are in isovolumetric contraction
- C. When the ventricles are being passively filled, the valves between the atria and ventricles (atrioventricular valves) will need to open. When pressure in the ventricles is higher than in the arteries, blood will flow into the arteries - there is blood exiting the ventricles, so the ventricles are contracting, so the atrioventricular valves need to be closed to stop backflow of blood into the atria. When atria are in diastole (filling) and ventricles are in systoles (emptying), the situation is the same as I just described for B.
- Q:Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?
- You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.
- Q:So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.
- This drop tube is the suction line. This tube will always be below the water level in the well. I would talk to a competent water well company and get their recommendations. Regards, Dale
- Q:okay, where the dome is on the head (where the flat part of the valves sit) the intake is uneven and the air+gas mixture escapes threw the open space when the piston goes up into the compression stage, and ignites shooting flames out of my exhaust port. the space is small but u can see light threw it when the valve sits there. Would some kind of Liquid metal work? or gas+heat resistant epoxy work to take the place of the missing space? I would file it but that would not be precise and time consuming, and i would buy a new head for $150, but the dealer doubles that price! and no way am i paying $300 for a new head. any comments would be well appreciated!
- take bike to dealer and get it fixed right.
- Q:And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :)
- I think your tech is adressing valve system deposits from your description. It can be done chemically, or with a shell blaster. Dirty injectors can be removed and sent for repair. Your car is pre OBD II, there is some experience and expertise required with cars before this because some of their problems won't set a code and require a real tech who had daily exposure to their habits, the fuel quality you can buy, your maintenance and repair records etc. Try the ford dealer for an evaluation of your current part usage and diagnosis of your symptoms. they should have your answers within the first hour. or, they may suggest a few tests. Getting aftermarket parts on your car over a period of years can make a diagnostic soup for a tech to pick-a-part.
- Q:My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.
- No...but heart valve surgery is rather routine for all but the concerned relatives and patient who tend to worry.....people do very well with replacement heart valves.....
- Q:Whilst pumping up my new tubular tyre, the head of the presta valve snapped off! Because this is a tubular tyre, I spent a lot of time (and cash) gluing it on and applying it etc, so I'm reluctant to buy a new tub. Is there any way getting a new presta valve head without replacing the whole tyre?Thanks in advance.
- By the head of the valve, do you mean the lock nut? The part you unscrew to press in to release pressure? If that is what you mean, it has happened to me several times. It is usually from the way the pump is applied or released from the valve. Hand held pumps cause it more than floor pumps. The thin screw that the nut tightens on simply snapped. It can even happen on a presta inner tube. You can just inflate and ride with the nut broken off. Shouldn't be a problem. If it is like any tubular I have used the valve core is replaceable. This is because tubs come with one length valve and for dish wheels you need to install an extension. Ask your bike shop if you don't know or look up the manufacturer's site for the brand tub you have. They usually say if it has a removable valve. If they don't come out and specify if the valve is removable or not, if they sell extensions for their tires it is replaceable. The extensions are supplied with a little tool to remove and tighten the valve. Simple pliers can be used if you are careful not to squeeze the valve too tight.
- Q:I have to get a new vacuum switching valve for my 1987 toyota pickup. I was just wondering what it does, and if a broken one would cause my truck to not idle. It still runs fine when i drive it, but when i push the clutch in the RPM's get really low until it dies.
- This valve probably is the EGR control valve - the computer monitors the EGR flow and controls the EGR valve opening by switching vacuum to it for opening or bleeding vacuum off for closing. If this valve fails to completely close the EGR valve at idle, the problem will mirror your symptoms
- Q:Specifically, what is the mechanism which leads to pressure drops in expansion valves?
- THERMOSTATIC EXPANSION VALVE A temperature-regulated valve that controls the amount of restriction to refrigerant flow between the receiver/drier and evaporator. Like the Fixed Orifice Tube, the Expansion Valve is the boundary between the High and Low sides of the refrigerant system. Unlike the Fixed Orifice, the Expansion Valve can regulate the flow of liquid refrigerant to the evaporator to either increase or decrease evaporator cooling based on the temperature of the refrigerant tube at the evaporator outlet. In vapour compression ref. cycle,The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. The auto-refrigeration effect of the adiabatic flash evaporation lowers the temperature of the liquid and vapor refrigerant mixture to where it is colder than the temperature of the enclosed space to be refrigerated.
- Q:I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?
- if the spark plugs are bad the oxygen sensor with sense the exhaust is not hot enough and the computer with allow the injectors to let more gas in thinking that since theres no fire it needs more gas causing it to run like its flooding and exhaust readings will be high. make sure the air filters clean
