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:This kind of faucet how to open, I law to wear a rod to take a trip to the poem But the stream removed the wrench, see inside the plastic, is the packing nut? What tools to remove? Question added: more
- After removing the wrench, there must be a nut where the four sides or six sides can be wrench with a wrench to twist this part of it
- Q:We all know that in the slowly open the faucet, the water is obviously slow, and then slowly all the faucet flail gnome gypsum pork chulan open, the water flow faster and faster, more and more, But we have played such a game, the faucet by the water pipe, pinch the other end of the water pipe, let go of a small mouth, the speed is not very fast, the solution is also a small export, why the difference between before and after so big? More
- Faucet outlet inside the core to play the role of control of water flow and limit the flow of water at the same time have a bubble effect, so the outlet core is also called "bubbler", different structural effects are different.
- Q:Kitchen faucet can not shut how the matter
- Hello, the faucet can not be sure that your faucet is really broken faucet, if you can do their own hands can get their own, the first law and spacious satiation and so soliciting but slippery step, first judge your faucet is a single Water or double water (hot and cold water), to buy the corresponding spool (double water about 12-20 yuan). The second step, ready to replace the tool. Such as hands-on ability is not strong for the new bar Faucet is very expensive case, the faucet removed to get the building materials store please change. I hope my answer is helpful to you.
- Q:My house a water pipe out of the water is very small, but other (for example, the toilet) in the water is the normal tripod feet to catch the non-non-stone wear, that is, the water pipe is small, how is this going on?

- Q:How to make a faucet sealing gasket
- The faucet sealing washer is silicone. Silicone (Silicagel; Silica) Alias: silicone rubber. Is a highly active adsorbent material, is an amorphous material, the chemical formula for the mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica gel because of its different manufacturing methods to form a different microporous structure. The chemical composition and physical structure of the silica gel determines that it has many other similar materials difficult to replace the characteristics of high adsorption performance, good thermal stability, chemical stability, high mechanical strength and so on. Silicone rubber has a high resistance to high and low temperature, ozone resistance and weather resistance, in the -70 ~ 260 ℃ operating temperature range to maintain its unique use of elasticity and resistance to ozone, weather and other advantages, suitable for the production of gaskets.
