Q: how could you make a valve or a system so that when it is pressurized, if enough pressure is reached in the system the valve will open completely and remain opened until it is close manually?I'm thinking about this in the context of an air powered dart gun, so that the firing mechanism is like a piston, and when a certain air pressure is reached, the valve that connects to the barrel will open and fire the dart: One thing you can do is get a pressure switch and a solenoid valve so that when whatever you are pressurizing comes to a certain level the switch will close it's normally open contacts and energize the solenoid which will open the valve. However as soon as the pressure level goes below the trigger level the valve will automatically close.

Q: It started leaking slowly so I opened the release valve for about 20 secs than closed it back to see if that would help, but now it leaks even more. So I had to shut off the water that's coming into the water heater and know I can't use the hot water in my house. Can someone help me please!!!!: i find it better the telfon paste instead of the tape,use paste and not leaks,should find it in the plumming supplies

Q: When and why do you need to get a valve job? My car has 85k miles on it. What is the difference between a valve-job and valve-adjustment? what would the increase in power be on mine? 3800 series 2 engine, assuming it is just a little old, no major problems. 5-10hp?: MOST modern engines have hydraulic lifters, which pretty much eliminates the need to have any periodic valve adjustments. You can take stock heads to a shop and put two grand into them and make better flow and bigger valves and more power, or actually buy a set of performance heads for less and make more power. the only time your valves would need to be set is when putting together a new engine, or taking apart the one you have and replacing say a head gasket or something. (in which case you would have a shop go through the heads and make sure they are up to factory specs. If your engine is running fine, and you have kept the oil clean and the motor in good tune, follow the recommended maintenance intervals in your owners manual. a valve adjustment is not going to give you horsepower.

Q: I know nothing about toliets - so please bare with me. The water valve underneath my toliet is dripping and I have to turn off the water in order for it to stop. It's really annoying to have to turn the water on when I want to flush it and have to empty out the container that is catching all the time. I think it has something to do with the valve itself and I'm PRETTY sure something behind it needs to be tightened - Has this happened to anyone else? What did you do?: There is a small nut around the valve handle on the valve tighten this one

Q: A friend of mine who is 26, was just told by her doctor that she has aenlarged heart valve. Is this really serious? Will she need surgery? Why can't I find any info on the internet? Please help I'm really worried. Thanks: there are two valves in the heart, a bicuspid valve (two flaps) and a tricuspid valve (three flaps). A valve serves to prevent the back flow of blood in the heart, keeps it all flowing in one direction. An enlarged or incompetent valve would obviously be unable to do it's work properly. How serious the issue is depends entirely on the extent of enlargement. Enlargement is usually a result of uncontrolled blood pressure issues, but can also be genetic. As she is seeing a doctor about this, suggest that you let the doctor worry about it.

Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =): No, it's ok, they are both the same. I've been using trumpet oil on my trombone slide for the past 4 yrs. It is less expensive, ad usually in stock. It's not bad. If i've used it for 4 yrs. I'm sure you can use it too! my BFF even used to use my trombone oil, that's how i ran out in the first place. I hope you do well with your instrument! Both are made of the same oil products. But i don't reccomend using cooking oil, or vegtable oil, it is too thick and makes the slide/valves greasy and is very hard to get off. Hope this helps.

Q: My mum (73, non-smoker, not overweight) has been diagnosed with 2nd degree aortic valve stenosis 5 years ago. Now deteriorating. Her cardiologist sees her every 6 months and strongly recommends surgery. She is too scared as dad died during a coronary bypass op. Any tips how to gently make her feel better about the op? She heard on the radio that some valve replacements can be done via catheter, not necessitating open heart surgery and heart-lung-bypass. Is that true for aortic valves and is it likely to become mainstream soon? She lives in Germany, so I guess good centres would be Munich, Wuerzburg and Heidelberg. Any views very appreciated!: Without surgery, a person with aortic stenosis who has angina or signs of heart failure may do poorly. Possible Complications * Arrhythmias * Endocarditis * Left-sided heart failure * Left ventricular hypertrophy (enlargement) caused by the extra work of pushing blood through the narrowed valve Aortic stenosis can be cured with surgery. After surgery there is a risk for irregular heart rhythms, which can cause sudden death, and blood clots, which can cause a stroke. There is also a risk that the new valve will stop working and need to be replaced. According to a prospective, single-center, nonrandomized study of 25 patients, percutaneous implantation of an aortic valve prosthesis in high risk patients with aortic stenosis results in marked hemodynamic and clinical improvement when successfully completed. Medium- and long-term results are unknown. When selecting the optimal therapy for individual patients, the percutaneous approach must be carefully weighed against the excellent results achieved with conventional surgery. Please note that I am not a medical professional.

Q: What would be some drivability issues with an EGR valve that is acting up. The valve in question is an electronic egr valve.: You really need to find a competent mechanic. (sometimes easier said than done). I have worked on cars for over 20 years and have NEVER seen a vacuum leak cause this kind of erratic behavior. If the codes will not reset, either the mech. doesn't know what he's doing or you have major computer problems. It may need to be replaced. The computers in vehicles are very reliable but not perfect. From what information you have given it seems that is the case. Before you go that route there are several sensors on this motor that could cause this. crank position, throttle position, mass air flow, etc. EGR would not cause this either. It have also seen coils breaking down cause this. This will get worse the longer the motor runs. (heat makes it worse). If you are not one to work on your own car I would start going to some differnt shops. Some times small shops seem to know more about troubleshooting than the dealerships.

Q: I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?: Heres to the brotherhood.Have fun!

Q: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?: There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.
