- Q: I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
- The proper oil at the right locations should free up the valve. Sometimes the grease from the slide accumulates in your valve, but oil will loosen it up for a short while. Some sugetions are to take out all the slides and snake and flush them with water as best you can. You should do this to your lead pipe about twice a year as well. Reoil everything and regrease the slides with a quality product. If its still gummed up ,its likely you will need to have the valves removed and professionally cleaned.
- Q: Situation: The males in my family have mitral valve prolapse, while I do not.If anyone could answer some of the following questions, it would be amazing! Thank you so much!1. Is this an X or Y chromosome disease? (I thought since it was just guys, it'd b Y)2. If so (or not), is there any reason why I don't have it?Thanks again! (:

- Q: List words that rhyme with valve...I need these.
- Sorry to all those saying salve and halve (and one could add calve) -- in these words the L is silent! Thus for valve there is no PERFECT rhyme (defined as using exactly the same sounds from the vowel of the accented syllable to the end of the word). The best you can do is a NEAR rhyme in which most of the sounds match, with as few sounds changed as possible, and the 'substitutes' matching as closely as possible. These COULD include dropping the L altogether, but I'm not so sure that salve, etc. work very well Varying the vowel: delve, elve [from a scientific acronym], helve (handle of a tool such as an ax), shelve, swelve ('to swallow'), twelve revolve, solve Varying the final consonant (and possibly the vowel) The closest match would be changing /v/ to /f/, but these words, again, mostly have a silent L (half, calf, ). The only exception? The name Ralph also changing the vowel: elf, shelf (but the -v forms are better matches) a voiced /th/ (as in this NOT thin) is fairly close to the /v/ sound -- as a result mouth (the verb form) might work. (why does mouth work better than salve? Perhaps because the ow sound is closer to the al of valve than to the short-a of salve, cat, etc.) health and wealth --with a changed vowel and un-voiced /th/ is little tougher, but maybe. . .
- Q: okay, where the dome is on the head (where the flat part of the valves sit) the intake is uneven and the air+gas mixture escapes threw the open space when the piston goes up into the compression stage, and ignites shooting flames out of my exhaust port. the space is small but u can see light threw it when the valve sits there. Would some kind of Liquid metal work? or gas+heat resistant epoxy work to take the place of the missing space? I would file it but that would not be precise and time consuming, and i would buy a new head for $150, but the dealer doubles that price! and no way am i paying $300 for a new head. any comments would be well appreciated!
- Without knowing actually how big the space is, I'm hampered in my answer. If the valve isn't bent, you may be able to lap the valve and seat. Your service manual should have directions on how to do this. Or you may even be able to grind it out with valve-grinding compound. I've gotten away with using valve-grinding compound heavily in some cases that probably should have been lapped. I put the valve in it's guide and attach a rubber hose and drill to the end of the valve. Then, after applying the compound to the seat and valve, I spin the valve while gently pressing on it's head. I keep adding compound as needed. I've done several this way with no problems. But if you have a big gouge you will probably need to get a lapper.
- Q: Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?
- NO THERE IS NO WAY TO TELL IF YOU HAVE VAVLE TROUBLE ONLY SPECIAL TESTS LIKE A ECHOEKG OR A CATH
- Q: does it moves up and down with the valve stem??
- A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve.. not sure if you are talking about tire valve stems? if so the poppet valve moves within the valve stem. I have also heard them referred to as Schrader valves see link
- Q: Does the new valve get glued or anything or do I just put it on tightly? I cannot tell if the existing valve is glued on or not.
- Is the new valve or the old valve the compression type? If the old valve is then as you take it off you will discover if it is glued (I doubt a compression valve is also glued). Replace the old valve with the same type as the old one. That is always a good rule of thumb to follow. Put it on tightly but DO NOT over-tighten it. 1/4 turn past tight it usually tight enough. I am not a big fan of compression fittings in either copper or cpvc. You may wish to put a glued valve on, if you already have the cleaner, the primer, and the glue, other wise the expense of the materials does not warrant their purchase for the changing of one valve.
- Q: And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?
- If it is a regular brass valve, you will have to drain the tank first, then replace the washer in the valve with one rated to be used for hot water. You replace the washer just as in any valve by removing the bonnet and stem. there you will see the washer. You may want to clean the area of any calcium carbonate that may had developed on the seat before putting it back together. If you decide to replace the valve, it is a 3/4 inch male NPT hose bib valve rated for hot water service. Personally, I've always thought that if I ever had to change one of those valves, that I would replace ti with a good ball valve that had a threaded hose end screwed into the discharge end for better drain flow. The whimpy valves that they put on water heaters is pathetic! If you use your favorite search engine and just search for water heater drain valve, you will find all kinds of cool replacement valves!
- Q: how much is a head and valves job for a 92 chevy silverado 1500, v8 5.0L, extended cab, 204,xxx miles
- A replacement head is about $200 plus labor to install A valve job is around $80
- Q: I assembled my new gas grill, but I'm not sure if the burner pipes (aka venturi) are properly connected to the valves. My assembly matches the picture in the instruction manual, but I'm not sure if the seal is tight enough. How do I know? Do I attach the propane and test? I'm concerned about the safety of doing so. Thanks!
- The connection between the valves and the burner are always a loose fit on an average gas grill. The regulator controls the pressure of the propane between the tank and the valves. The valves control the flow of gas. The propane leaving the valve is forced through a tiny orifice as it exits. This tiny orifice serves two purposes. It increases the pressure and velocity of the escaping gas, which helps speed it in the right direction. This, in turn, sets up the venturi effect. The venturi effect is a fancy way of saying that the system, from the valves to the burner, is designed to pull in air. There are usually little rectangular shaped vents in the burner tubes located where the burner tube connects with the valve. These vents allow air to be drawn into the system in order to ensure that the propane has enough oxygen to obtain complete combustion. Too much air is better than not enough. The second purpose of the orifice in the valve is that it doesn't allow the flame to travel back down the line toward the tank. The orifice is to small to allow enough oxygen to be sucked in to the closed part of the system to support combustion. Very good safety feature. Plus, the propane exiting the valve, even on high, is so minimal that a roaring fire from just the flow from the valves is improbable, maybe impossible. Gas grills are safe. People are dangerous. The main thing is to make sure you see a flame somewhere within the first 2 to 3 seconds after turning the valves to on. If you don't see any flame after 2 to 3 seconds, turn the valves to off, give the grill a chance to air out. You can even fan it with a newspaper or something. You just want to ensure that you are never trying to light propane that has had a chance to build up and mix with oxygen. After airing the grill out, either figure out what the problem is or try lighting it again. They aren't that complicated. Go ahead and get that grill fired up. The kids are hungry. Hope this helped.
