Q:I have a road bike that has schrader valve tubes and my current tire is rated to 90 psi max. I ordered some new tires that are 100 to 120 psi max. Will the schrader valve tube hold that kind of psi? I dont really want to buy converters and new tubes right now.

Schrader Valve Pressure Rating

Q:Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks

A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.

Q:i want to know where we must use swing check valve and where we must use lift check valve in petrochemical companies. what are the differences ? are they different from the appearance? how can we distinguish between them visually?

A swing check valve consists of a flap or disc of the same diameter as the pipe bore, which hangs down in the flow path. With flow in the forwards direction, the pressure of the fluid forces the disc to hinge upwards, allowing flow through the valve. Reverse flow will cause the disc to shut against the seat and stop the fluid going back down the pipe. In the absence of flow, the weight of the flap is responsible for the closure of the valve. Lift check valves are similar in configuration to globe valves, except that the disc or plug is automatically operated. The inlet and outlet ports are separated by a cone shaped plug that rests on a seat typically metal; in some valves, the plug may be held on its seat using a spring. When the flow into the valve is in the forward direction, the pressure of the fluid lifts the cone off its seat, opening the valve. With reverse flow, the cone returns to its seat and is held in place by the reverse flow pressure. There is typically a larger pressure drop across a Swing check valve than across other types.The lift check valve has two major limitations; firstly, it is designed only for installation in horizontal pipelines, and secondly, its size is typically limited to DN80, above which, the valve would become too bulky.

Q:My house has hot water baseboard heat. In the basement, there is a wood burning stove (now it is like a radiator) that has the pipe system going through it Between the pipe in and the pipe out is a valve. Does it have to be opened or closed all the way? There is no other way to control the heat in the basement I was thinking of opening the valve half way, but I do not want to destroy the valve.

If its open all the way it would be hotter so I dont think it would hurt nto keep it half way

Q:okay, well, I understand partials. But, on a trumpet, what does each valve do? I mean, I had this idea that each one was a half-step up from the previous...but that's not true. Is there some sort of pattern to them? Does each one have a different purpose?...Please answer as basically as possible. I don't play music very often, and I definitely don't speak brass-ish.

Q:wut is the purpose of this valve on tanks and on piping? explain wut the vacuum part does and wut pressure does? thanks

The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.

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 $$??

Q:It seems like the shutoff (stop) valve for the toilet is preventing my toilet tank from filling up for flushing. When I shut the valve, and open again, the water flows into the supply tube that flows into the tank for a few minutes. Afterward, the flow of water stops BEFORE filling the tank as if it lost pressure of water flow.I repeat the above (closing and opening valve) and does the same thing. (There is also no sign of leak...)What can I do? I'm hoping I don't have to call the plumber.

PEB could be top yet my journey has shown that this type of water hammer is led to with the aid of the ballcock interior the bathroom. The fill mechanism interior the unit in simple terms starts off vibrating after a whilst. try this little try; Flush the bathroom and spot if the vibration takes place while the bathroom is in finished top off mode, (waft top down, a brilliant sort of water entering the tank) - or does the vibration take place while the tank is in simple terms approximately finished, (waft is beginning as much as close off the fill mechanism). you additionally can try with the aid of pushing down on the waft ever so particularly while the tank is done - you will probable hear the vibration at that element. base line - replace the ballcock and all might desire to be properly.

Q:im looking at buying a 1995 ford probe, but it has a busted valve in the head, does anyone know how much it would cost to have fixed?

When you say busted valve, do you mean a bent valve, or a broken valve? if you meant broken valve, i guarantee you my friend, that car is something that you do NOT want to invest your money into. a broken valve can cause and may have already caused all sorts of further damage. this can include exhaust fumes leaking into the cooling system and over-heating the engine, engine cylinder or gasket leaks causing oil to mix with coolant, broken timing belt, blown head gasket, and the list goes on. i HIGHLY recommend you stay clear of a broken valve. if you meant bent valve, this is generally not as serious, but is something to be very cautious of. the best way to check for a bent valve is to have a compression check done. a mechanic can do this, or you can do it yourself if you buy a compression checker. if the valve is indeed bent, the first thing you will want to find out is WHY it got bent. generally this happens because the timing belt slips or the valve has a leak from being stuck open. if this is the case, you might be looking at coughing up $300, maybe a little more, maybe a little less. but before dumping your money on fixing a bent valve, you want to get a professional inspection and make sure that this bent valve didn't cause damage to anything else. i hope this will help you with your question and with your decision on buying or not buying the car. good luck!

Q:any flash files explaining valve operation maintenance will be very much helpful

A pressure regulator is simply a device designed to maintain a certain pressure on a system or piece of equipment. A safety relief valve is a device designed to prevent the over pressure of a system or piece of equipment. The intent is to prevent a failure, rupture or explosion. The basis for the design of a pressure regulator is governed by good engineering practice while a safety relief valve in most cases is also governed by specific codes, regulations and laws. In the United States local boiler and pressure vessel regulations are the most common governing agency along with the ASME/ANSI Codes.
