- Q: In aircraft reciprocating engine, if valve spring surge happen?1. Why happen?2. Affect to engine?3. Result?4. Feeling?
- Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough
- Q: Can you please explain to me what an atrial valve is and what it does??
- By atrial valve, I assume it meant the atrioventricular valves. Basically, in the heart, the blood flows from right atrium, right ventricle, left atrium, left ventricle. The atrioventricular valves are the tricuspid and bicuspid valves. They make sure the blood flows from the right atrium - right ventricle and left atrium - left ventricle respectively and prevents blood from flowing the wrong way in those chambers.
- 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: In my condo, I have what appears to be a water relief valve of some sort right after my water inlet pipe. It's after the water cutoff valve. It's not the water heater relief valve. It has a leak, not bad, just a drip right now. It looks like a half baseball sticking out of the main inlet pipe with a bolt in the center of it. I've tried to tighten it but that makes the leak worse. First, what is this. Second, Is there an obvious fix to this. Third, if I have to get it replaced, what model/manufacturer can I get so that this doesn't happen for a long while. My plumbing is short of fifteen years old.
- It sounds like a pressure reducing valve. As you tighten that bolt it increases the pressure and made it leak more.It's probably not any good. I think if you go to a home center you'll find one . probably a Watts brand. They seem to be more prolific. Not hard to change.
- Q: I don't know exactly what it is called...the water valve from the wall to the toilet is leaking. All of the parts need to be replaced. They appear old and corroded. Can you please tell me what these parts are called? About how much they cost? And is this difficult to do? I found an excellent video on youtube on how to replace..but just want to ask anyway if it's difficult..it doesn't LOOK difficult.
- It's called a shut off valve, costs 6-7 dollars depending where you buy it. You will have to match the size of the valve to the size and type of the pipe coming out of the wall, could be copper or threaded steel pipe. Also replace the line from the valve to the toilet, this will have to be matched to the valve as well. Not a hard job but matching up all these things can be tricky if you don't know what you are looking at. Might be easier to get a handyman or plumber. If you do try it yourself do not forget to turn off the water - might have to turn the whole house off.
- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- In depth answer is: The Arterial Valves The semilunar valves are mere membranous pockets, and have no tendinous cords attached to them; but on account of the extent of their convex attachment, when their free margin is made tense by the pocket being filled from the artery, the valves can only pass a given distance from the wall of the vessel and are thus held firmly in position. The force of the blood leaving the ventricle distends the vessel and pushes its wall away from the less elastic valve. When the force begins to diminish, the blood passes behind the semilunar flaps and raises them from the wall of the distended artery. The moment the current from the ventricle has ceased to flow, the pockets are forced back by the aortic blood pressure and bulge into the lumen of the vessel, so that the convex surface of the lunated portions of each valve is pressed against corresponding parts of its neighbors. Their union, which is accomplished by their overlapping to some extent, forms three straight radiating lines, and is a perfectly impervious barrier to any backward flow of blood
- Q: So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
- Well some what true an egr mifht create a vacuum leak making the engine run faster but to burn a piston it woul have to be close to the cyl like a intake leak easy way to check for vacuum leaks is to take a can of carb clean and spray down the intake and listen for idle change (don't spray dist)
- Q: so here are the details. i've been using my trumpet for about 6-8 years now and 1 if not 2 valves get stuck on my trumpet. the problem is not the oil as i have over oiled them too and no go. its that when i try to put my valves back in their place and twist them they don't stay in place,move ,and making either my valves stuck or making my trumpet not do a sound. what should i do? repair shop or buy a new one? i hear the clicking sound when i put them back but still all that does is either make my valve more sticky
- Trumpet valves have metal or plastic tabs that fit into grooves on the casing. They keep the valve in allignment. It sounds like the tabs on your horn could be broken. I suggest letting a repair shop do the work.
- Q: Hey I was wondering how I can test the compression of the valves. Also if they are leaky. I'm thinking about valve rebuilding because my M series conn 8d was bought a few months ago and it was a school instrument. I like how it plays but I feel like there are things that should be done. The valves are one of them. So if there is any test for the valves please let me know. Thanks
- If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.
- Q: So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks
- To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.
