- Q: hi im 13 years old and i am having my tricuspid valve repaired or replaced the doctors do know what they are going to do yet.what is the success rate of the operation ?and whats the survival rate of the operation ?all other info would be appreciatedthanksalex

- Q: i have a 1970 chevy sb 350 and i need to set the valve lash what is the proper method and where do i start? everything is stock!
- Just read this again last light. The motor should be hot an normalized before you start. With one valve cover off clean the cylinder head of all old cork gasket residue lay a new gasket on the head and screw the valve cover bolts through the gasket into the head a few threads. There are companies who sell neat little clips that slide on the push-rod end of the rocker arm to reduce the leakage of oil from the push-rods through the ends of the rocker arms. We're going to hear all sorts of whining and disagreement here but Chevrolet hydraulic valve lifters must be adjusted with the engine running. It's written in a factory overhaul book. The oil pressure from the oil pump has to adequately pump-up the hydraulic valve lifters so you can get proper adjustment. Using 3/8 a deep well socket and a long extension, loosen counter clockwise the center rocker-arm nut slowly till you hear the rocker arm clatter. There's two trains of thought how and why the center not should be adjusted. GM says to *very slowly turn the center nut till the clatter disappears. Slowely continue turning the center nut 3/4 more turn clockwise. William Tyler Grumpy Jenkins (Chevrolet race engine builder) always said to turn the center nut to stop the clatter plus 1/8 of a turn more. He did this so the plungers inside the lifters were extended nearly all the way out. This was done to reduce hydraulic lifter pump-up and valve float at high RPM. For the detractors who don't think this is correct, pull the valve covers off a 265, 283, 327 or a 350 with hydraulic lifters after the engine has been off for 30 minutes. You will see every rocker arm is holding the valves in the closed position. It's impossible to adjust the valves with the engine off.
- Q: I have 06 Suzuki gsx-r 750 and i was wondering what are the signs or how do i know that my valves need to be adjusted?
- Buster Brown is right on the money. Most bikes have double overhead cams these days and the valve clearance tightens up and can cause burned valve faces or seats. Single overhead cam engines using rocker arms tend to loosen up and will clatter more. He's especially on the money about keeping track of valve clearances at each check. I've done that for years as well as keeping record of compression readings.
- Q: hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?
- I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
- 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: what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
- Are you referring to heart valves? They don't really get clogged, but can get calcified and what we call stenotic (the area through which blood flows is reduced). There are ways to manage valvular heart disease with medications, but some people require surgery and valve replacement. There are mechanical and biologic heart valves that can be put in place of a damaged valve. The surgery is one of the riskier ones, because it's on the heart.
- Q: this valve uses in fire water lines...
- Deluge valves are used in special fire sprinkler systems. Open sprinklers or spray nozzles are attached to piping and to the valves. The valve is connected through control valves to a water supply system. The deluge valve consists of a housing, a swinging clapper like an ordinary check valve and a retractable keeper to hold the clapper tight to the valve seat. Electrical pneumatic or hydraulic mechanisms can retract the keeper, causing the valve to open. Other attachments provide for alarm sensors, gages and the like. See one at the link below
- Q: I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?
- Find the meter, the shut off valve will be within a foot of the meter, If the meter is digital and on the outside of the house, look for a closet, or cupboard near the meter on the inside of the house, the meter will be concealed there.. The valve you are looking at is a shut off valve for the heater.
- Q: Specifically, what is the mechanism which leads to pressure drops in expansion valves?
- I would wager that those losses, or pressure drops, are due to entrance and exit losses through the valve. Calculate the losses yourself. The mechanism is simply friction and geometry. Perhaps the losses are not what some agency says they are. Physical tests can be used should such phenomena govern costly criteria and baselines.
- Q: I have mitral valve prolapse. Just recently Ive been getting chest pains more often * few times a day* and the panic and anxiety have gotten worse. I had a pain last night that lasted about 10 minutes and it was very uncomfortable.I know mitral valve prolapse is a condition that usually not a threat. But can it get worse over time with some people?My doctor already knows I have it but should I go back to have more tests done?Im kinda scared because my symptoms are getting to be more than what they were.Any advice?
- sounds more like anxiety to me.I agree wid Rhianna
