- Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- They are called porcine valves... they are used very frequently because you don't have to be put on anticoagulation. But, the down side is... they only last about 15 yrs and then they have to be replaced. A pigs heart is pretty close to a human one.
- Q: My friend had heart surgery and it was pretty serious. She got a new heart. Days later they checked her and discovered that she bursted a heart valve. The doctors say it's one she can live without. That really concerns me. The valves connect directly to the heart. Please help.. Will she be ok if she doesn't get it replaced?
- If she has a ruptured heart valve it needs repair or replacement. The valves serve a critical role in maintaining normal flow of blood through the heart. Without the valves blood will backflow and cause buildup and many problems. Maybe she is stable and can wait for surgery at a later date? I'm not aware of a situation where you can live with a ruptured valve. I hope she is in good care.
- Q: i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
- What, just the valve? What valve? A stop valve in the supply or delivery line? Or the temperature and pressure valve? There's no way on God's green earth I'd ever fork over $300 for this job. I can do it myself in thirty minutes. The TP valve would take less than ten minutes. Granted I'm a handyman and I have a shopful of tools and 20 years experience. But back in the day, when I'd never done any maintenance work, I replaced my own water heater from start to finish and it only took a couple of hours. Unless there's something major going on that you're not disclosing to us, it sounds like a pretty serious overcharge. [edit] To answer your additional questions, I wouldn't pay that much to replace all three valves. The valves themselves aren't very expensive, and the only really difficult part of this entire operation is getting all the water under control to replace the drain valve. Something's going to get wet, and that tends to make homeowners annoyed and difficult customers. The TP valve is a simple wrench-in, wrench-out replacement. Water off, power off, drain below the level of the valve and out it comes. Control valve requires turning off the house's water, but less draining. Replacing the drain valve requires draining the entire heater but again it's a wrench-in, wrench-out job. Easy.
- Q: Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...
- Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
- Q: Hey guys. I need help. Sorry this might not go here... but i couldnt find a 'good' category to put it in. This is for an engineering project for college.Im looking for shielded core solenoid valves that can with stand 95-98% sulfuric acid. With this in mind not very many materials are usable, right now we are looking for HDPE (High-density polyethylene).The size of the valves and cost is unimportant. Main thing is finding someone who sells HDPE solenoid valves.For more clarification on what we are looking for, below shows a shielded core solenoid valve from ASCO. The more acidic resistant material they offer however is a FKM. Which can only withstand ~60% sulfuric acid solutions.
- In practice, engineers do not use solenoid valves directly on chemical or process lines. They are bound to leak and cause danger particularly in your case of 98% sulphuric acid. Use a mechanical valve actuated by a motor (since cost is no issue to you) If an air supply is available, then you can use pneumatic diaphragm valve operated by a solenoid valve. Motorised valve has slower fixed open close time VS faster adjustable open close time for air operated valves.
- Q: I was just informed that my 4 year old daughter has been diagnosed with mild mitral valve regurgitation. I have been researching, but only find the information to apply to adults, not children.What general course is taken when dealing with children with this condition and what should I expect? Her pediatrician was treating her symtoms as asthma with breathing treatments, but, I was not comfortable and took her to my family physician, who sent her for the echo, which discovered this.I'm more or less just looking at our options...
- my nephew had it and needed surgery.
- Q: Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.
- A bad EGR valve can cause a lot of headaches, poor running, bad idle, stalling, etc. One of the few things that it can't cause is overheating. Completely different systems. (side note, make sure that the problem isn't with your EGR sensor, and not the valve). For overheating, here is the diagnostic path: 1: Check for leaks, and that fluid levels are OK. 2: Check for bubbling in the radiator / resivour (while running the engine). Bubbles, especially at high RPM's can indicate a blown head gasket. 3: Check that the thermostat opens. To do this, start a cold car, and place you hand on the upper radiator hose. With gloves on, squeeze it. Wait for a few minutes until the engine warms up. The upper radiator hose will get hot and firm. This indicates that the thermostat is working and the water pump is working. 4: Keep the engine running, and make sure that the cooling fan starts up. Keep your fingers away from the fan. 5: If you can SAFELY do it, reach to the front of the radiator and carefully feel for cold spots on the radiator. If there are cold spots, that means that the radiator is plugged, and needs to be swapped. Good luck.
- Q: ok so the water main that comes into the basement the valve handle snapped off so how do i shut the water off so i can replace that valve? I called the water company and they said they cant shut off the supply to the house because it is private property and we have to call a plumber if so how can they shut the water off and on if we dont pay the bill?
- Broken Water Valve
- Q: I got a new gas stove, but I can't find a shut off valve to take the old one out and put the new one in. There isnt one behind the stove on the line, and i went under the house and followed the gasline and didnt find one down there either. Can any one give me ideas where else to look?
- theres one one by the gas meter
- Q: what is meant by inherent characteristic for the steam control valve??
- There are different type of valves, (ball, gate, globe, needle, diaphram) each have their own characteristics in how they operate and the effect they have on flow. Inherent characteristic would be an effect that valve has on the fluid flowing through it.(steam can also be considered a fluid ) An example is a globe valve used to throttle a flow does so by adjusting the size of its opening. In essense its a variable orifice. Flow through an orifice results in a pressure drop across that orifice. So, an inherent characteristic of a globe valve is a pressure drop.
