- 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: I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?
- === take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
- Q: I recently had an echo and they said their was a slight tricuspid valve leak but it was 19 and anything less than 20 is considered normal. I have no clue what that means. Does any one have and clue on what scale she was talking about. Also she stated that the machine are so sensitive these days that the majority of people are found to have some sort of leak. Is this the case??????
- finding on the severity of the valve situation it fairly is severe. If it have been severe you certainly could have indications that could assist you recognize previous to now. Ask the physician how severe the valve insufficiency is. A mitral valve prolapse could make you sense mild headed. The tricuspid valve insufficiency could convey approximately severe issues. There are various circumstances that would reason this. it fairly is great to your heart professional to describe your situation. In any experience it fairly is no longer something to fool around with or placed off. while you're actually not chuffed with the solutions do no longer hesitate to get a 2d opinion.
- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- The aorta and the pulmonary artery both start at valves from the heart, but I don't know if you could say they have valves. A lot of arterial flow is regulated by smooth muscles which constrict to direct flow to other areas. These are a kind of valve too.
- 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: Specify eight technical requirements that you would consider important, when deciding upon a particular control valve?
- 1] I assume that by control valve you mean a variable orifice valve, not an on/off valve. 2] An answerer to your other question listed Metallurgy, temperature, pressure and shutoff requirement To which I note that if you need a tight shutoff you should not trust a control valve to do that, but should add an on/off valve in series. Also, metallurgy covers corrosion requirements but not obviously so 3] To which I add: flow rate [or Cv] and pressure drop fail open or fail closed response time signal input [3-15 psi, 4-20 mA, 1-5V, etc] connections [ie, fitting type] packed vs sealed might need to look at hard seat materials and/or replaceable seats, to control erosion reliability, ease of maintenance, availability of spares, timing on that vendor permanence [ie, are they entering bankruptcy ?] Cost
- Q: I just fixed a clog in my bathroom sink by taking off the p-trap. I had turned off the water valve beforehand, and when I was done I turned it back on. After this, all that came out of the faucet was a trickle. Turning the valve in the off position does not stop the trickle. When I first turned the valve off before taking off the pipe, the valve was not turned all the way left or right. It was in the middle, but the water flowed fine. When I turned the valve all the way to the right, the water shut off at the faucet. My apartment is pretty old. Is this valve most likely broken?
- if your water valve has a plastic handle it is probably striped. take the handle off and try using pliers to turn the valve this will tell you what you need to know.
- Q: can you put a blow off valve on a chevy cobalt ss supercharged?
- A blow off valve is for turbo waste gate?not super charged
- Q: Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!
- 1. Would require dysfunction on a valve in the right heart generally speaking, so the options would be the likes of tricuspid regurgitation or stenosis, or even pulmonary stenosis. 2. PND is a result of heart failure, particularly regarding the left side of the heart (although of course both sides could be failing). Many valve problems could cause this as an end result... a bit of an odd question, but I'd go with mitral stenosis or regurgitation primarily. 3. Congested liver is the systemic blood system overload (like the oedema), so it is the right heart. Triscuspid regurgitation can cause a congested liver and if you felt this liver, it would be pulsating too. 4. Distended jugular veins are a sign of heart failure. Primarily right heart failure as it is causing blood to be backed up instead of passing through the right heart to the lungs. Tricuspid stenosis or plain old right heart failure (with or without left heart failure at the same time). 5. This is typical of left heart failure as blood backs up into the pulmonary system as the left heart is failing to pump into the systemic circulation. Similar things to PND can cause this. These questions though, are honestly a little on the vague side and half those cases would result from heart failure even without any valvular abnormalities...
- Q: 1998 camaro3.8L v6sometimes when i start the car, it makes this loud ticking noise that goes with the RPMIm pretty sure its the valve, anyone know how to fix it, and how much it might cost?
- The use of transmission fluid in the gas, and in the oil will act to clean the engine. People buy upper valve lubricants when in reality that is exactly what transmission fluid does. It is a very high detergent, very thin oil. It acts to clean an engine through the gas, and in the crankcase. You don't want to add a lot in either place, though. A pint in a tank of gas a couple of times or so, and just enough in the crankcase to thin the oil you have just a bit. In extremely cold weather when I have used a 30 weight oil in a vehicle I will add one quart to my crankcase to thin the 30W oil. It makes it around a 10 to 15W. As a cleaner, and an upper valve lubricant this way there is only one drawback to its use. If your engine is prone to using oil, ie, an older or worn engine, it will start to clean so well that you will start using more oil.
