- Q: what would happen if valve was not adjusted right? and please explain
- The intake valves allow a air/fuel charge to enter the combustion chamber, the exhaust valves allow it to leave. They need to close and seat properly so when the piston comes up on the compression stroke there is plenty of a compressed air/fuel charge for a strong combustion. Without this compressed charge you will have a little fire in the combustion chamber and not an explosion.
- Q: A diabetic patient undergone CABG having aortic valve problem.Cardiologist suggested valve replacement
- Today, there are two types of prosthetic valves used for replacement: mechanical or tissue. Mechanical Valves A mechanical valve is carefully designed to mimic the native heart valve. It has a ring, like your own natural heart valve, to support the leaflets. Like your own heart valve, the mechanical valve opens and closes with each heartbeat, permitting proper blood flow through the heart. To prevent any blood clots from developing on the valve, which can cause complications, a mechanical valve replacement requires you to take anticoagulation medicine (blood thinners) daily. The dosage of this medication is different for each person, so you will be closely monitored to make sure you are on the correct dosage for you. Regular blood tests will be performed at the physician's office, an anticoagulation clinic, or at home with a specialized testing kit. Tissue Valves The tissue valve is a native valve taken from an animal. Once the tissue is explanted (removed), it is chemically treated and prepared for human use. Some tissue valves have a frame, or stent, that supports the valve, and some valves are stentless (no framework). A very thin polyester mesh cuff is sewn around the outside of the valve for easier implantation. Eliminating the stent makes it possible for the surgeon to implant a larger valve. Larger valves generally provide more surface area for blood flow; this allows more blood to flow through the valve to accommodate the body's needs. Homografts or Allografts A homograft or allograft is a human valve obtained from a donor. This type of valve is particularly beneficial for pregnant women and children, because it does not require long-term anticoagulation therapy. In addition, it can provide excellent hemodynamic performance, allowing for natural function of the surrounding structures. Because the availability of these valves depends on donors, supply is limited. Take care always
- Q: I know what a valve is, but I would like to know what an actuator does?
- Valve actuators are part of a motor driven valve, the part that drives it. Generally it is an electric, hydraulic or pneumatic motor. The valve may be on/off, or regulated by a feedback servo system to open or close controlled amounts. The type of valve comes into it too, as some valves are more or less on or off, and others allow fine control without excessive force. Usually the valve and actuator are a package. Valves with actuators are useful for remote control and automatic control of processes. Some valves may need an actuator so they can be operated safely because of the hazards around them. Large valves may need an actuator because they need too much power to operate manually in a reasonable time.
- Q: I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
- i have seen many types of valves on an everyday basis. and i havent even seen one like this. its most likely a cheaper knock off brand valve. you have enough room to replumb a new one in quite easily. if you do not have enough room right before the valve to just cut it out, cut the pipe on the other side and unthread the valve from the threaded fitting. then buy some fittings and pipe and replumb it. you have a lot of room to work on it. i doubt you will find the same valve to part it out with. use either a Hunter valve or a rainbird valve avoid toros, orbits, weathermatic, and lawn genie parts. good luck and just take your time.
- Q: I had a doctor who was suspicious of me having a heart valve problem. I don't want to be on medication for the rest of my life. I only want to change my diet, pray, exercise, and meditate. I don't believe the doctor has that cure for that problem that's if it was a heart valve problem.
- It depends on what sort of heart valve problem you have, how bad it is, and how bad the symptoms are. Sometimes you don't need to do anything special except watch the diet and lifestyle, sometimes you need medicine, and sometimes the cure is surgical repair or replacement of the valve. I think prayer is a fine thing to help, but the Lord also gave us the skills so doctors could provide something a little more physical. If your heart valve problem is bad enough, it can cause damage to your heart and the rest of your body that all the prayer, diet, exercise and meditation in the world won't help fix. However, as a patient, it's always your decision if you want to take the doctor's advice or not. Otherwise you could find yourself dead, and explaining to God why you chose not to take the help He provided for you. So before you go making any decisions, you need to wait until you find out what the entire story is. Then weigh up all your options carefully,and decide.
- Q: How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?
- where is i get the packing gland material
- Q: this valve used in the refinery.
- This is a 'Trip and Throttle' (T T) valve that is maintained in a 'Fully Open' postion during normal turbine operation. It is maintained open by a Hydraulic Control system that, should any of many shutdown conditions occur, the hydraulic oil will be dumped to its reservoir by the operation of a Solenoid valve, actuated by the shutdown signal, and the T T valve will immediately close, stopping the steam flow to the turbine speed control steam chest in a safe manner. The valve handwheel is then operated to ensure that the valve remains fully closed until the system is ready for re-start. The valve cannot be opened again until the shutdown condition has been rectified and the hydraulic system reset to restore the oil pressure to the valve. The valve however, can then only be re-opened manually and slowly until the turbine is brought to the 'Minimum Speed Control' Governor setting. When settled down at this condition and the steam chest valves are under the control of the Governor, the T T valve is swung wide open. This latches the valve in the fully open position until another shut down occurs,
- Q: The pig heart is better than our heart but the valves can be used to help us.
- cape.uwaterloo.ca/che100projects/... They also use cow - bovine - for valve replacements.
- Q: How do you take out a valve stem?
- A valve stem and valve stem cap are two different things. If you have a good valve stem, you do not need a valve stem cap. People just use then for safety. You remove a valve stem, with would you believe, a valve stem remover, or some caps have a two pointed top that will remove the stem. Now where to buy them, most old fashion gas station, auto parts, or bike shops, even WalMart.
- Q: I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.
