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

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:What are the advantages and disadvantages of this method? Are there any other ways 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:Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.
- Is the flow through the valve. That is to say, when the valve is fully open, flow through the valve size.
- Q:What are the key valve enterprises in China? Mainly in those areas?
- Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
- Q:Can the gas valves be switched off regularly?
- Can often switch, for example, after cooking, you can turn off the valve after cooking.
- Q:What are the valve types H, F, and Y? What are the meanings of these 3 letters?
- Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide
- Q:the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold
- It is loaded against the supply and return water pipe is not underground do in next time if it is to see if there is any water on the side of the baffle remember from the baffle recently if it is normal that is motivated next must put off the baffle
- Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
- Q:Where is the valve used?
- Water treatment, chemical, petroleum, biological pharmacy and so on are more used
- Q:What does the "PN" mark on the valve mean?
- The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
- Q:someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- Get some water with your neighbors first, property. That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing 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
