Q:Trombone Thayer valve?
I'll tell you what, but I'm not an expert on Trombone case maintenance, but here's what you need to do. Take the Trombone case out side preferably in the full sun, open it up and lean it against a wall, or a secure object. Now run in the house a get some liquid dish soap and trot back outside to the case , and squirt the dish soap all over inside the case, top to bottom. Given you may have to lay the case down flat to do a good job, with the soap, about 3oz. is plenty. OK now stand the case back up , get the garden hose and use a spray nozzle, or use your thumb and spray the hell out of the inside of that Trombone case, paying special attention to the ends of the case. Spray that sucker until you've got soap and bubbles everywhere! Eventually though you will have sprayed away all the soap and bubbles and once that case rinses clear with the hose spraying find a nice new place to stand it up to dry, that is definitely in full sun, say at least 7-8 hours per day. Let the case dry in the sun for 2-days, may be longer depending, but leave it out there for as long as it takes for that material and fabric from within to become bone ss dry! Then get your horn and introduce it to it's new friend. NOTE: It does not matter what the case is made of metal , wood , plastic, leather or glass. It will handle the cleaning, not to worry, Blast it!
Q:pls. give the difference between Isolation Valves & Block valves?
An okorder.com/. There's numerous systems that use isolation valves. Let's say you want to make some ice cream, you open the isolation valve to let the milk flow into the mixer, then open the valve to let in the cream. Depending on the valve type, you could then open it to allow in the vanilla, sugar, egg, etc. All with the same valve. It just keeps the ingredients from coming in contact . A block valve is used to shut off a supply, so you can perform maintenance, or just stop the flow.
Q:Is mitral valve anything to worry about it?
i wouldn't worry too much at the moment your cardiologist and you dr will keep a close eye on it Medication can't correct a deformity of a mitral valve. such as diuretics are available to relieve fluid accumulation in your lungs or legs, which can accompany mitral valve regurgitation. High blood pressure makes mitral valve regurgitation worse, so if you have high blood pressure, your doctor may prescribe medication to help lower it. Following a low-salt diet helps prevent fluid buildup and helps control blood pressure looking going back yrs ago they used to replase them srtaight away but the diffrent tenics now they dont do it straght away but try to sort it with medication it can be repaired if the heart is not pumping very well but this is how a repair is done if your heart is not too bad Your mitral valve consists of two triangular-shaped flaps of tissue called leaflets. The leaflets of the mitral valve connect to the heart muscle through a ring called the annulus. The surgeon can modify the original valve (valvuloplasty) to eliminate backward blood flow. Surgeons can also repair the valve by reconnecting valve leaflets or by removing excess valve tissue so that the leaflets can close tightly. Sometimes repairing the valve includes tightening or replacing the ring around the valve (annulus). This is called an annuloplasty. It's important to have an experienced surgeon perform mitral valve repair i hope you find this an help to you but as i said you dont have to worry too much yet you have a good chance with your tests you can lead a pretty good life and if need be they would do more if it came to the worst hope this as helped you
Q:Loose Valves... What Do They Cause By Being Loose?
Loose valves don't actually cause any major problems or damage. The only loss is power and economy. A tight valve is what you don't want. A loose valve opens later and closes earlier than it should, so less air/fuel is getting into the cylinder. A tight valve can burn up because it may never actually 'close'. You won't hurt anything by continuing to ride the bike, but there is absolutely no reason why you should continue to ride the bike without getting the valves adjusted.
Q:Should propane come out when valve is open?
Even if you open the hand valve, there is a pin that will slide into place and close the opening to not let propane come out when the tank is not hooked up to anything....this is a safety feature, if your tank is spewing gas without being hooked up, it will still function....it's just a little less safe. I would say tighten the hand valve after each use to be sure there wont be any accidents later. best case scenario, replace the tank.
Q:Mayo Clinic in Rochester Minnesota and Mitral Valve Prolapse?
at the start, you ought to talk on your typical practitioner. they might certainly answer your questions extra proper than all of us right here. yet, i can assist you be attentive to that your situation can certainly be very uncomplicated. I certainly have a kinfolk member with an identical ingredient and he leads an exceptionally frequent existence and could no longer desire a valve alternative. If he engages in very actual interest (alongside with taking part in soccer), he does get drained certainly, yet different than that, he's high-quality. In case they did no longer clarify it to you (it seems they weren't very informative) right here is going: Your mitral valve is nearly a sprint door that opens and closes on your heart. once you have a mitral vavle prolapse, what which ability is that as quickly as that valve swings close, it closes and definitely swings IN slightly too far. (Ever seen a swinging door? comparable thought) This reasons slightly a leak. it is a few thing which will ought to be checked each few years in the process your existence, to verify that it does not worsen. touch your typical practitioner and ask her or him those questions, just to be on the risk-free ingredient.
Q:Riding with a Schrader/Presta valve adapter?
Yes, just leave it on the valve while you ride. I tuck mine in my seat pack, but there's no reason you can't put it on the valve. The presta valve should be screwed shut like normal, then just put the adapter on over it. One of the best little gadgets to have if you ride in the country. Lots of people have portable or shop air compressors, but only *real* cyclists will have a pump or air chuck to fit a presta valve. If you inflate your tube with CO2, be sure to let it thaw out before you unscrew the adapter to close the presta valve. It's easy to lose air or tear the rubber at the base of the valve if you don't. I rode with a guy that used to just tuck his adapter and a patch kit in the leg of his shorts because he wanted to travel ultralight. I guess you could do that, too, but I'd worry about driving them into your flesh if you happen to crash and land on them.
Q:Testing my EGR valve?
Most it could go either way depending upon the failure mode (stuck open, stuck closed, leaking, etc). I use a hand operated vacuum pump ($20 at most car parts stores). Connect it and see if you can draw a vacuum and if it holds the vacuum That will tell you if the diaphragm is okay. Also check the valve seat itself to see if it seals properly when closed. EGR valves run about $20-$50 depending upon car. Also, just because the EGR valve isn't working does not mean the valve is bad. You could have a faulty or disconnected vacuum line preventing the valve from operating. That was my problem in stead of replacing the EGR valve and the catalytic converter as recommended by an Emission Repair Station located just outside the state emission test station. The repair station is no longer in business.
