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.

4.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:Gate valve z11h/y-16 what does that mean?
Product Name: internal thread gate valveItem number: Z11HProduct specification: DN15-50Product pressure: 1.6MPa-2.5MPaMaterial: cast iron, cast steel, stainless steelInternal thread gate valve nominal pressure 2.5Mpa, applicable temperature range -20-232-350, applicable medium: water, oil, gas and certain corrosive liquid (W.O.G), thread type G.NPT.BSPT.BSP.DIN259/2999.
Q:What are the main types of gate valves?
According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve.
Q:What is the difference between gate valve and gate valve? Is it the same valve?
Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
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:Which is more expensive, bronze gate valve or brass gate valve?
The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.
Q:What does gate z41t-10 150 mean?
