- Q: i would like to hear from anyone who has actually had the work done. i also would like to know if the valve worked.
- A backwater valve is basically a check valve that lets water flow in one direction only, away fom your system, and prohibits any other accumulation from entering into your system, like flood water etc. Yes they work very well unless they get full of junk and stuck open. You can install it yourself on the sewage line, they are about 50 bucks, its simple
- Q: I just found out about my condition. Is it dangerous? And will I need surgery? My mom just got her monocuspid valve replaced. I don't wanna have to go through the same thing. And will I still be able to go on rollercoasters? I'm going to cedar point tomorrow. I only want answers from people who know exactly what there talking about thanks
- so, as you already know, a typical aortic valve has three cusps. yours has two, so this is a structural issue. the point of these cusps, or leaflets, is to maintain blood flow in the appropriate direction through the heart and to the rest of the body. having a bicuspid aortic valve can be something that you inherit from one of your parents. did you have a murmur that prompted them to look for it? if your valves are young and healthy, there's probably not a problem. when it can become problematic is with age, where the leaflets can become calcified and hard, then they can not open as well (i.e. become stenotic), or not close properly (i.e. become regurgitant). if either of these two things develops, and becomes bad enough, they consider valve replacement surgery. but this is the kind of stuff that happens over years and years. you should see a cardiologist, if you haven't already been referred to one, because this is a medical condition that gets watched over time, and then if it gets bad, it gets treated. while it's not bad, it gets watched. this cardiologist will follow you over time, in addition to your regular family physician. he/she will also be keeping an eye on your aorta (the big vessel that blood enters after it goes through the aortic valve), because sometimes people who have bicuspid aortic valves also have problems with your aorta. i would also talk to your cardiologist about whether or not you need to take antibiotics in advance (i.e. prophylactically) of any dental work. i.e. because of your valve with a different shape, are you more predisposed than the average person to getting an infection there. but go to cedar point if you're young and healthy. a roller coaster should not give you any sort of problems. enjoy yourself!
- Q: What are the requirements for valve automation?
- Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.
- Q: how do u remove a valve seat from a head, and install the new one?
- takes a stand up mill. to cut the seat and heat the head and install the new seat...
- Q: Hi all,My 1995 nissan altima (122k on the odometer) stalled for a few minutes this morning. I noticed that one of the sparkplug holes ( where the cable from the distributer connects to the spark plug) is sorrounded by oil. I cleaned it out and it got filled with oil again. luckily for me, and by god's grace it somehow started normally and i drove home. I am sure its the valve gasket. There is not much oil leakage, the oil level is fine.I need to know if its going to damage my engine if I ignored the problem for 3-4days.Thanks.
- becareful it might hurt electrical stuff on the car. i would have valve cover gasket replace with new spark plug gasket for valve cover too.
- Q: what to use to inflate self sealing tube with the presta valve?
- You okorder /
- Q: how do you adjust the hyd. valves when motor is running?? thanks, jerry swain
- The adjustment is a mess if you don't have the clips that go on the rocker arms to stop the oil from splattering all over the place. If you want to try it without the clips, then you simply use a socket on each rocker lock nut and back the nut off until the valve starts to click, then tighten the nut back down until the rocker stops clicking then turn it an additional 1/2 turn. Its much easier to adjust the valves to zero lash without the engine running. to do that, follow the adjustment procedure in any Chilton or Haynes manual to put the engine at either TDC or BDC and adjust the valves in the sequence that is specified. Zero lash essentially means you can't move the pushrod up or down when the rocker is tightend down to the point where all freeplay is removed. I'd recommend duing the zero lash adjustment rather than adjusting them with the engine running hope that helps
- Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- The problem could be that the crank shaft has not been turned to the place to adjust the valves. The push rods could be the wrong length ones too.
- Q: Well I had a Anginogram that said I have Mitral Valve Stenosis with the LVEDP was Moderately Elevated and My Right Ventricular Moderately Elevated and My Right Atruim is Moderately Elevated what do all this mean I see my cardiologists in two weeks to go over things. Oh yes they don't say how much the Mitral Valve is narrow.
- Actually, stenosis means narrowing, not hardening. (From Websters: New Latin, from Greek stenōsis act of narrowing, from stenoun to narrow, from stenos narrow) Mitral valve stenosis is often pretty benign (not dangerous), but it can be if it is severe. The elevation of the atrium I guess means that the atrium is larger than is should be, but as that's not a term I'm familiar with, I'm not sure. If the Valve is narrowed it does take more force to push the blood thru, so the walls of the atrium would become larger as they have to work harder. Definitely see your doc and find out just what's going on.....but calm down. Most people that have this don't even know it. There are clear medical treatments that are very effective....and worst case replacement of the valve is really a fairly routine surgery (for the docs anyway....they've been doing this for 25-30 yrs at least)
- Q: What are Atrial valves??
- there isn't a sinoatrial valve in the human heart. There are 2 AV (atrioventricular) valves, and 2 semilunar valves, which are the aortic valve, and pulmonary valve. The AV valve seperate the atrium (on top) and ventricle (on bottom). Blood flows down from the atrium, to the ventricle, and then the AV valve closes to keep blood from going back into the atrium. While the valve is closed, the ventricle contracts, which send blood up through, the aorta ( left side) or the pulmonary trunk(right side). The semilunar valves seperate the ventricles from the aorta and the pulmonary trunk.
