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

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 does valve DN50/80 mean?
- DN50/80 refers to the size of the valve. That is, the circulation diameter is 50mm/80mm.
- Q:What does "TD671F" mean?
- Refers to the pneumatic centerline of the clip butterfly valve, but I really do not know what the T represents what, but also may be some manufacturers own company's product specific model, do not understand.
- Q:How does the valve open?
- The general water switch valve and valve is counterclockwise, but there are some special components are clockwise off, specific can correct the switch travel around open to see, do not be too fierce force damage to the switch, you can switch with a wrench
- Q:How to check the quality of the valve?
- First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.
- Q:What's the advantage of using three way valves?
- Three way valve generally has a cut-off, regulation, diversion, and prevent counter flow, voltage regulation and overflow and other benefits, because of its benefits more, so the use of the three valve is extremely extensive, in the valve industry is also very important.
- Q:Who knows which kind of water valve is good?
- Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.
- Q:What are the main equipments for valve production?
- Press machine, CNC lathe, instrument lathe, drilling machine, machining center, assembly line, pressure test bench, plane, measuring instruments, etc.
- Q:I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?
- In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
- Q:Valve difference
- Valve difference, or you should ask the classification of valves, valve classification, there are several sub methods, some according to the model, and some are by use, then each kind of valve is divided into several categories and models. Take the trap for example, it is a kind of valve, and then it is divided into steam traps, air traps, float traps, and so on. If you really want to know the difference between the valve you search the Internet under the classification of the valve, there are a lot of articles, or you directly to the trap inside www.ssfmsh find an article on the valve type article, can not give you a specific address, is not allowed here. You work hard, go find kazakhstan. I hope my answer will be helpful to you.
- Q:Air compressor out of the gas with what kind of valve control okay, globe valve or other?
- If the factory uses, it is recommended stainless steel ball valve
