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 do the Z, J, H and D represent in the valve type?
:Austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material
Q:What kind of valve is it? How do you see the status of the switch?
This is a ball valve, that is, usually said cut-off valve, to determine the switch state is carefully look at, there is a switch on the status of the arrow, you will understand.
Q:What are the ten major brands of China's valves?
If you want to buy fluorine valve, you can go to Shanghai corrosion-resistant valve group Co., Ltd., and what questions contact me?!
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:Where is the Shandong valve? How about joint valves in Shandong?
Zigong Sichuan power station valve factory is a professional power equipment supporting valve factory, mainly power plant high temperature and high pressure valve, plug valve, ball valve, temperature reduction and pressure relief device
Q:Suddenly no water at home, asked about the property,
You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.Pressure values are the only indicators that distinguish these valves.
Q:High and low pressure valve is how to distinguish?
Ultra high pressure valve nominal pressure PN = 100MPa; high pressure valve nominal pressure PN10.0MPa ~ 80.0MPa; medium pressure valve, nominal pressure of PN2.5MPa ~ 6.4MPa; low pressure valve, nominal pressure PN is less than or equal to 1.6MPa
Q:Why use the pump outlet valve to adjust the flow rate?
Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.
Q:What valve is the VENT?
In order to reduce the leakage point, sometimes before the factory will be welded to death.DRAIN position must be in the lower position of the valve body, is generally able to reach the lowest point.
