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.

 

2. Main Features of the Gate Valve:

• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber

•  Free of water pollution

• High manufacturing accuracy

• High strength

• Environmental protection and energy saving

• Good visual effect

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 is the difference between the copper gate valve and the ordinary material gate valve?!
The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
Q: greater than DN50 of the pipeline butterfly valve?
Have not heard of this requirement, before the ball valve and butterfly valve quality is rarely used now are good, can be used, but not easy to control the flow valve butterfly valve can close more time-saving, fluid resistance of small. HVAC branch pipe, to flow control, so the choice of gate valve and cut-off valve is more reasonable, and now choose a ball valve is also a lot.
Q: What else, P54140V, 170V? What do they mean?
P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar
Q: What is the difference between cut-off valve and gate valve?
Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
Q: What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
Q: What are the structural differences between parallel and wedge valves?
The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.
Q: What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
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 is the gate valve for the DN65 hydrant?
Fire hydrant with 65 butterfly valve, ah, how do you use the gate valve?
Q: Fire protection gate valve from the wall how many distance there is no regulation?
1 meters away from the wall, leaving the maintenance and replacement distance
