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?
The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
Q:What are mine valves?
In fact, much, no matter what the industry, with many types of valves. You want to see what works on the use of what media, in the choice of what type of valve is more appropriate.
Q:What valve is the VENT?
VENT generally use a check valve (resembling a screw, spring preload), also directly using the plugA two-way sealing type ball valve for example, in order to detect the leakage of the pressure after the end, also for pressing the cavity is convenient, usually in the body cavity external to the up position to open a checking leak, which is VENT.
Q:The valve is rusty and can not be opened. What shall I do?
There are pictures, for different valves, then choose different ways of opening.
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective.
Q:What valve is the FCV?
It's FCU, Fan, Coil, Unit, fan coil valves
Q:What does valve A335P22 mean?
1. What does valve 13Cr&FHF mean? 2, valve WC6 (F1113Cr&FHF WC6 body material
Q:Dalian hi Max Valve Co., Ltd.
I have to do the technical sales colleagues is high inside out now before the inside sales revenue is also good about one hundred thousand a year as sales of a great degree of luck the.I do not know what the specific circumstances, what age, in this line for several years, there is the opportunity to communicate with the landlord and make progress together.
Q:How to open the gas valve with drawings
It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
In fact, this is only the valve industry sector argument, not necessarily to distinguish between very clear.As long as the customer pressure requirements, we give him the drawings on it.Valve flange thickness and valve thickness are not standardized, according to pressure requirements.The flange thickness of 6.4Mpa and 10Mpa is completely different from that of valve body.For example: general gate valve, the most basic pressure 1.6MPa, according to GB/T139272008 and JB/T90921999 standard castingGenerally selected 1.6MPa, when the highest pressure pressure is 1.6X1.5=2.4MPa, if you exceed this pipeline pressure is not, there are now many manufacturers in order to save costs, the valve wall is thin, a conventional valve pressure 1.6MPa is a bit difficult.My own boundaryVacuum negative pressure 0.05Mpa-0.5Mpa0.6Mpa-1.6Mpa belongs to normal pressure (low pressure)2.5Mpa-4.0Mpa belongs to medium pressure6.4Mpa-10Mpa-16Mpa-25Mpa-32Mpa-42Mpa belongs to high pressure50Mpa-80Mpa belongs to supercritical high pressure valve
