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:Where is the filling portion of the valve?
The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.
Q:Valve pressure test
The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
Q:I want to act as a proxy valve
Many of them are now in Fujian valve valve agent many manufacturers are now seeking cooperation in the valve and pump after all or many different places to the other industries also need a process to proxy depends on your targeted customer base is better than the brand also has the advantage of brand price comparison
Q:How can the material be checked by valve approach? What experiments do you need?
First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:Which valves are installed in a directional manner?
Very simple answer to your valve, in addition to gate valve and butterfly valve (single line up, first closed), such valves are not directional, and other have
Q:Our company is doing valve exports,
If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those
Q:Valve legend
F means the initial letter of the valve, which is shown as a stop valve
Q:Mechanical valve
Tiemuyu666, let's go inside and see if there's anything we need. For reference only
Q:How does the valve close?
This is a relatively vague ah, like the stem ah, usable spanner clamping, clockwise rotation in the end. The handle should be closed groove and the coincidence place.
