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.

4.FAQ

1. What's are the characteristics of gate valve?

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. 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. 

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:700r4 throttle valve......?
The only thing i can think you could have done i bent the peice that comes out of the trans. If the throttle valve still returns like a spring when you pull it with your fingers and you can still hook the tv cable to it it should be fine. unhook the tv cable at the carb or throttle body to hook it to the valve then hook it back to the carb or throttle body.
Q:ford escort pcv valve?
VERY easily. The rubber hose that is routed to the top of the throttle body on one end, is connected to the PCV valve on the other end, where the exhaust manifold is situated, by the radiator cooling fan.
Q:is valve working on portal 3?
No, they're not going to make portal 3. Even if they were, how the hell would we know?
Q:Are valve stems replaceable from one tire to another tire?
I am having some problems understanding your question. Valve stems go in the rim not the tire. It is always advisable to replace the valve stem when replacing tires. Be more specific an we can give you a better answer.
Q:boiler bleed valve replacement?
Very easy but quite slow. Open the bleed points on the upstairs radiators and the system will fill evenly. Shut the bleeds when the water reaches them of course. If the pump is accessible loosen the big screw head on the top of it and the will bleed air from the pump. When you think the system is full and the noise of entering water stops then go around to all of the upstairs radiators and check that there is no further trapped air.
Q:EGR Valve question...?
It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring
Q:What happens before, during, and after an aortic valve replacement?
Mechanical valve will last for ever. But the red blood cells will be damaged and clot will be formed in the implanted mechanical valve. In order to prevent the formation of blood clot, the patient has to take warfarin (a blood thinner) for the rest of his/her life. If pig valve is used, there is no necessity to take the medicine (warfarin) for the rest of his/her life. But the tissue valve will function only for 15 years. Since you are too young, you have to opt for mechanical valve and to take the medicine for the rest of your life. Valve replacement is indicated for virtually all who can tolerate surgery. In younger patients, the patient's own pulmonic valve can be used, providing good durability; a bioprosthesis is then used to replace the pulmonic valve (Ross procedure). Most often, the aortic valve is replaced with a mechanical or bioprosthetic valve. You will stay in an intensive care unit for the first 2 or 3 days following the operation. Your heart functions will be monitored constantly. The average hospital stay is 1 - 2 weeks. Complete recovery will take a few weeks to several months, depending on your health before surgery.
Q:why do valves need to be adjusted and shimed on amotorcycle?
Your prospective Hyosung may require some more frequent adjustments because the initial wear on its machined surfaces would still be polishing each other off.... surfaces like your hardened valve seats against the sealing surfaces of the valves... Or, the hardened surfaces of the cam lobes against the rocker arms. If your Hyosung's engine has been properly engineered, then its components have been properly case hardened. After their initial microscopic machined imperfections have been polished smooth, they shouldn't have to be checked as often. The Hyosung 250 was designed in Hamamatsu Japan by the same people who design Suzukis. It should turn out to be a great motorcycle. Perhaps frequent valve checks are because it's high revving and air cooled.?.? I owned an air cooled KZ550 Kawasaki, once. It required valve checks every 3000 miles. On the other hand, my wife has a 2007 Corolla. It has a low revving, Double Over Head Cam, 4 valve per cylinder LIQUID cooled engine. It requires valve adjustments every 60,000 miles.
Q:Automatic hydraulic cylinder reverse flow valve?
Hydraulic Reversing Valve
Q:Which side is open for a pipe main shutoff valve?
left to open an right to close piece of cake. (grate now i want some cake)
