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:What gate DH10016, AM
The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.
Q:What are the meaning of the cast rigid gate valves z41h-16c?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
Q:Gate valve Z41H-16Q generally used for what place?
It is a standard flanged gate valve with engineering pressure 1.6MPa. Generally used in chemical processes, of course, can also be used for municipal and civil engineering. The valve is generally used for cutting occasions fully open or fully closed, is not suitable for flow regulation.
Q:Function of gate valve
Valve strengths: (1) fluid resistance is small, due to the valve inside the valve channel is straight, and the medium flow through the valve does not change its direction of movement, so the fluid resistance is small. (2) the opening and closing moment is small, opening and closing more effort, as the gate valve opening and closing, the direction of movement of the gate and the direction of the media movement vertical, compared with the cut-off valve, valve opening and closing more effort. (3) the direction of the movement of the media is not limited, no disturbance, no pressure reduction, the media can flow in any direction from both sides of the gate valve, and all can achieve the purpose of use, more suitable for the direction of the movement of the medium may change in the pipeline. (4) the length of the structure is relatively short, because the gate of the gate valve is vertical inside the valve body, and the stop valve clack is horizontally placed in the valve body, so the length of the valve is shorter than the cut-off valve. (5) the sealing function is good, when the full opening, the sealing surface is less eroded. (6) when fully open, the sealing surface is less eroded by the working medium than the cut-off valve. (7) the shape is relatively simple, the forging technology is good, and the scope of application is wide.
Q:What is the soft seal gate valve?
Commonly used soft sealing gate valve model is divided into: Z45X and Z41X, the difference is that the Z41X is the Ming bar, and Z45X is dark rod.Matters needing attention in packing and transportation of soft sealing gate valve:Soft sealing gate valve before transport, should use the rope to tie up the small caliber.Before transportation, the lighter sides of the valve should be sealed.For larger caliber soft sealing gate valve, it should be used to carry out simple packing, it can better prevent the valve in the process of transportation damage.
Q:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
Q:What is the difference between a flanged gate valve and a wire gate valve?
Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together
Q:Does the tap belong to a stop valve or a gate valve?
Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.
Q:Is the gate valve flanged?
The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
Q:What's the meaning of flexible z45x-10q door valve?
Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve
