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:Why does the centrifugal pump start and stop in the case of closing the gate valve?
The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.
Q:Can the soft seal gate valve reach 25 kg?
Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
Q:What is the soft seal gate valve?
Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
Q:What kind of valve is gate valve? Is it different from the cut-off valve?
Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
Q:Gate valve DN65 what does that mean?
DN65 indicates that the valve bore is 65CM.The gate (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.
Q:What kind of copper gate valve copper content standards, there are no national standards?
Usually copper alloy, rarely used pure copper, there are GB
Q:What is a protective gate valve? What is gate valve knowledge?
it is up to the function of a single valve can not reach the exit of the product is installed in the water supply pipe and the head of civil air defense to conveying medium to stop, wave and wave combination, to prevent internal shock wave into the system engineering facilities, so as to eliminate the destructive shock wave, to protect the system facilities normal operation and safety protection purpose.
Q:Stainless steel gate valve DN150 200300 weight, who knows?
The weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.It's not that heavy at all
Q:TitleThe difference between gate valve, butterfly valve and stop valve
The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
