Q4:What Is Our Normal Payments Terms?
- Q:My AC leaks and mechanic says it is shrader valve. Is it expensive?
- No okorder /
- Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
- A Schrader valve coming loose is a rare occurrence. If you didn't damage anything and the valve core itself is coming loose, there's a tool to tighten them. Old-fashioned valve caps actually had this tool built in. You can still buy the tools for a couple bucks at auto parts stores. But of course, a new tube will cost about $3 and solve the problem.
- Q:-air pressure of 40 psi only -run on 12v or 250 vac-no need for half open or any of the options i just want it on or off-it will be for a costum use so i dont need any special designs for it any thing will work -it also can be change from gas to water if
- Automatic okorder /
- Q:I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.
- As the valve shuts down, the diaphragm will vibrate as the pressure changes from one side to the other, then it will Thump as it seals. This is normal. However, to isolate the squeak, you may check to see if there is a 1(backflow preventer installed, 2) (if built into the valves) the variable pressure screw on the top of the valve is set correctly. The variable pressure screw usually has a cross top handle (older ones had a dial) and should be set so that on a high pressure line, it shuts down fairly quickly. If this is open all of the way, it can cause the diaphragm to squeal by slowing the internal pressure change to shut it down.
- Q:wife died at 40 still awaiting results of exsaminers report. Can CPR be given to some one with two artificial heart valves mitral and arotic? She the person administering CPR be aware that they are in the heart...
- Yes, and it doesn't matter if there are artificial valves or not. The thing about CPR is that it's only done for someone who is actively trying to die. The alternative to doing CPR is to let someone pass away, which is not usually the best course of action (unless they have a terminal disease and have asked not to be resuscitated.) If you are asking whether the presence of heart valves excuses someone from NOT doing CPR... then no. If you are asking whether heart valves + CPR and a bad outcome is because CPR should not have been done, then no to that too. The right thing to do for someone who is pulseless is to start CPR, call 911 and get more definitive treatment on the way. CPR is not going to revive someone - it is only a bridge until a defibrillator and/or cardiac drugs are available. I'm sorry that you lost your wife at such a young age, and I hope you find the answers you are looking for.
- Q:Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
- It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
- Q:what is the difference between the pinch valve and gate valve / knife valve? If someone can help me explain / show me the complete structure of pinch valve and the way it operates, thats better
- a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.
- Q:Is it possible that if you never adjust valves the engine could lose a lot of compression? 1990 Suzuki VX800, 19,000 miles on the clock. No idea if it has ever had the valves adjusted, only got it 3,000 miles and 6 months ago. It is now not running and after a compression test, has 90 psi in the rear and 150 psi in the front cylinder. Don't really have the time yet for a leak down test. Could the exhaust valves be the cause of the low compression? thanks.
- Yes it can lose compression if your valve lash is too tight. This can also cause the valves to burn. Adjust your valves as soon as you can.
- Q:automotive cylinder heads and valve
- Valve rotators are just that, they cause the valves to rotate during operation preventing wear in only one spot there by extending the life of the valve and the valve seats.
- Q:I have a intake valve leakage in both my car and truck. If there some sort of quick fix i could use to stop the leakage for about 1 month.
- what is leaking in to where? assuming that your talking about the intake and exhaust valves,then here goes. if the car and truck are old enough to have a carb on them then if you have gas leaking past the valves then you will need to clean the intake valves, if it's oil leaking into the cylinder then you will need to change out the valve seals-those are located under the valve springs. to do that job you will need an air compressor.if it's compression blowing past the exhaust valves then you will need to pull the heads and have them serviced, same with intake cleaning. sorry no quick fix. either fixed or malfunctioning,those are the choices
