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.

5.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:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better
Q:What's the difference between valves and valves without valves?
The advantage of carrying valves and venting valves is that they control the amount of exhaust and prevent other fluids from flowing out.
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
Q:What is a heavy body valve?
You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!
Q:Add a valve on the trachea, when the valve behind the use of gas units,
Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation
Q:Can the angle valve of York central air conditioner be replaced by other valves?
Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
Q:What kind of valves are best used for sand drain valves?
Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......
Q:Internal structure of valve
To answer your question was the top valve is not open on the thread of an analogy between ordinary wood screws and nails is a straight out of another can only rely on the screwdriver to turn out the cut-off valve is from the mechanical analysis of text as a specific principle is not specific
Q:What does valve A335P22 mean?
May be non-standard label bar, do not understand, A3 should refer to the body, the material is 13Cr.
Q:What does "1/2" mean on the valve?
Indicates that the ends of the valve are 1/2 inches in diameter. 1 inches is converted to metric system of 25.4 millimeters.
