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.

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: The basin faucet has been replaced with glass glue
- Basin faucet has been fixed with glass glue, then you can slowly use the knife blowing
- Q: Faucet outlet outlet diameter 21mm, inner wire is how much? Can not buy the appropriate bubbler, how to do?

- Q: Seek the toilet water pipe specific height
- Water pipe installation Note: 1, the water should be equipped with indoor total valve, before installation must check the water pipe and connecting accessories are damaged, trachoma, cracks and so on. 2, the installation of kitchen, Wei Guan Road, the size of the pipe in the wall should take into account the final size of the wall after the paste, that is, in advance to consider the thickness of the wall. 3, the wall, the ground, as little as possible with or without connecting accessories to reduce the risk of leakage points. Connect the accessories to ensure that the installation, no leakage. 4, the design of water pipes should be considered when the washing machine faucet installation location, the layout of the water.
