1.Structure of Gate Valve Description

A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. 

2. What is the work principle of gate valve

 The gate faces can form a wedge shape or they can be parallel.

Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q: We have a 2008 grizzly 700...Lately when we run the 4-wheeler there is a ticking like noise (as is something were loose). I have been told by a few people that it sounds like the valves need adjusting. Does that sound like what it is? Will it cause any damage to the 4-wheeler if we ride it before we get a chance to adjust the valves?
They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long
Q: I am 16, and i have a leaky heart valve. What makes it worse so i can try to prevent from it getting worse? please help.
It would be very helpful to know which valve is involved. At your age a bicuspid aortic valve would be the most common congenital heart lesion. Regurgitation tends to increase over time no matter what is done. There is nothing that you will be able to do to prevent this from getting worse if that is the nature of the valvular abnormality. If you provide me with additional information I may be able to offer a more thorough and thoughtful response. I wish you the very best of health and in all things may God bless. JR
Q: My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?
I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.
Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?
Just shut the water off to the house and then you can change the faucet without having to mess with the valves. If you want to shut off the valves though just use a pair of chanel locks to turn them once you break them loose they will turn easier. If the handle breaks off it no biggy, it wont hurt the valve any, you just wont have handles but they dont work anyways right.
Q: had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning
freeze the line coming to the valve, with a co2 fire extinguisher, or dry ice, then swap the valve, and let it thaw
Q: I was wondering if anyone knew how important tire valve stem caps were in maintaining inflation pressure in auto tires? I noticed one of my tires losing air slowly (from 30 psi to 21 psi in about a week) and this tire (unlike the other three) also had a missing tire valve stem cap. I've just replaced it, and was wondering if a missing valve stem cap caused faster loss of tire pressure.
Tire valve caps are the final seal again potential failure in the valve of the valve stem. A good tire valve cap will come with high quality rubber seal that push against the circumferential 'ring' of the valve stem and thereby help to contain the air should the valve fail or not containing the air very well. You observation of your tire (the one with the missing cap) losing air confirms that this could be a possibility. Of course, the other possibility is that your tire is having a slow leak - go to any petrol station, and it could be rectified at a minimal cost. Note: Even if the valve is perfectly good, if the tire go over a bump or pot hole, it is still susceptible to lost of air due to the additional pressure asserted during the hit.
Q: Is there any application usuage of ball valve in comparison,most engineers opinion is as Valve size get reduces in reduced port.Other than this what paramteres decides in selection of either of one

Q: recently changed head gasket. could valves tap from the push rods being mixed up? they all seemed to be the same size and i know the other side was exactly the same when put back together but this side is mixed up. could this make the valves go crazy? and i need to replace my water pump because its getting very hot and no coolant moving. and everything is smokin up, took off oil cap and it was steaming. would that have anything to do with making the valves tap?
When you replaced the head gasket, did you properly adjust the valves, as in preload? Doesn't sound like it...as for different length push rods, you'll have to check that repair manual you went by...you did read the repair manual, right? As for the rest, head gaskets must go on only one way. Did you make sure all the holes lined up correctly, and one or more cooling passages weren't blocked by the gasket? Torqued properly, in sequence? Were the intake manifold and exhaust gaskets installed and torqued properly? Sorry to be a nag, but as you can see there is more to it than just unbolting and rebolting parts...
Q: I'm thinking of buying a used 2006 Volkswagen Jetta. It has a 1.5 liter 20 valve engine, and I really don't know what that means. That's good, right?And is this a good used car to buy?
Are you sure its a 1.5 liter 20 valve engine? Jetta's of that year came with a 2.5 liter 5 cylinder engine (which would have 20 valves, 4 valves per cylinder.) Basically what valves do is some open to allow air to enter the cylinder, and then some open to allow the combusted mixture of air/fuel to exit. Most vehicles (to my knowledge) have four valves per cylinder nowadays, I know it was less in the past, but I think just about all have four valves per cylinder now. Five cylinders is just one more than four, one less than six. Oh, and Jetta's are actually quite nice vehicles. I would definitely pick one up if I were in the market for a used car, and found one at a decent price.
Q: I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?
if the spark plugs are bad the oxygen sensor with sense the exhaust is not hot enough and the computer with allow the injectors to let more gas in thinking that since theres no fire it needs more gas causing it to run like its flooding and exhaust readings will be high. make sure the air filters clean
