- Q:the air valve, how does it propel a paintball in a blowback operated paintball gun how does the size/shape/?? of the valve impact how fast the paintball shoots?
- The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.
- Q:Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training
- The heater control valve has nothing to do with the A/C.
- Q:My furnace cut out about a year ago. The hvac guy i used told me the gas valve was no good and that the flu was partially blocked. I cleaned out the flu, he replaced the gas valve ($700+) and it worked great for a year. Today the furnace does not fire up. Pilot is working. I cleaned out the flu (there was definitely quite a bit of debris, so that was probably the cause for the shut off) .... The flu is now clear, but when i turn the system back on the thermostat calls for heat, but there is no gas flow to the burner... could the valve have failed that quick, or should i be looking at something else like the CO sensor or something... just looking for some direction before shelling out another 700 bucks... Thanks in advance for any ideas or assistance....
- There are a few possibilities. The valve runs on a low voltage line. The low voltage is provided by a transformer. It it possible the transformer is bad. Be sure the power switch to the furnace is on. (should be on the side of the furnace. Easy way to check is (on the thermostat) turn the fan switch from auto to run. The blower fan should come on. Check that the gas valve is in the ON position.(if you have had to light the pilot it may still be in pilot position.) Another possibility is a clogged gas line. If you have an older home rust can accumulate inside the iron gas lines. Where the gas line attaches to the furnace there should be a drip leg. This is a short length of pipe that points down with a cap on it from the TEE that goes into the furnace. This short piece of pipe is to catch any moisture or rust that comes thru the line. First TURN OFF the gas at the shut off in the pipe it's self. This is a quarter turn valve. When the handle is in line with the pipe the gas is on. When it is opposite the pipe (pointing out to the side) the gas is off. After turning the gas off, remove the cap from the bottom of the drip leg to remove any accumulation.USE PIPE DOPE not teflon tape when putting the cap back on.Turn the gas valve back on and check for leaks.
- Q:I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink
- Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.
- 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 a clogged EGR regulator valve cause my car to stall out and die when it's idling at red lights?If I give it a little has it wakes the car up and keeps it from dying.One mechanic told me it was clogged up and that it can cause that issue. My boss says there's no way that's the problem... I say we've fixed cleaned or replaced just about everything else...Is this true or is the mechanic just trying to pocket a bit more $$??
- The thing you did not say was if you had any codes. If the valve was stuck and that would have to be in the open position you would have codes for the O2 and the EGR. And that includes the answer from Cleonitro. Your more likely to have dirty throttle body butter fly's and a dirty air by pass or MAF sensor which ever your vehicle has.
- Q:This is in continuation to a question I posted earlier today.....In trying to remove the shut-off valve (that is for a dishwasher hookup) from the main hot water line under the kitchen sink, it just turns and turns and turns in the same spot w/out showing any threading.How to I get this removed so that I can either replace it or put a stopper on it so it will quit leaking?
- If you have copper pipes attached to the valve, they need to be heated with a propane torch and remove the valve. Once this is done install a new valve by sweating in new solder joints. Many sites show how to do this in detail and isn't that difficult. If the valve is attached with nuts, remove them and get new ones with the new valve. Make sure to use teflon tape on the threads when installing and tighten.
- Q:I'm at school reading a mag and all the internet is blocked except yahoo. So i'm trying to figure out what the diff is between 3 angle versus 5 angle valve jobs.
- Cylinder ports flow better with a fancy four or five angle valve job. If you look at most standard valves there is only one contact point all the way around the valve face that actually seals on the valve seats. The width of this surface in multi-angle valve jobs is just as it sounds. Instead on one 45 - 46 degree angle. the valve will have two to three additional angles toward the valve stem under the valve head to smooth out the intake flow of fuel and air into the combustion chambers. there also may one to two additional angles above the sealing surface of the valve for the same reason. The actual part valve of the valve face that sits on the valve seat may be very narrow 3/32 to .060 This is especially true of the intake valves. Not so true of the exhaust valves. The exhaust valves need all the cooling they can get and the valve seat is the only saving grace of cooling them off. Therefore the faces of the valves are a bit wider. The narrowed up intakes however are constantly bathed by cool air and fine droplets of gasoline.
- Q:Surly Pilots don't just switch the fuel selector valve of mid flight
- Do you know for certain that it was, or are you just repeating unfounded rumors? What's your source for this information?
