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.

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: Which industries need valves?
3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).
Q: What does valve J41H-16C mean?
J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel
Q: Is there any problem with connecting the geothermal valves with other geothermal pipes?
Can be universal,Material is the same, the fuse will not cause shrinkage when you can use
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: 1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect
1. can be understood that way2, check valves, stop valves, and throttle valves are called valves3., welding, thread, and there is a cylindrical indentation, as well as plastic deformation press in4, without opening, there is a sphere or other block, open the moment, the pressure will come down, the media through the channel, attack or blocked by the ball, huh, huh5, the pressure self tight refers to the middle flange, where the greater the pressure, the more reliable sealing, within a certain rangeWhen the cut-off valve diameter is less than 150, the medium is low, the inlet is higher and the outlet diameter is greater than 200Some of them are self locking by thread, and some of the globe valves are equipped with locking devices
Q: Which valves are used in the power station?
Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
Q: How to check if the gas valve is open?
Method 1: gas valve has a handle, the handle is parallel to the pipe, that is open, vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the handle is parallel to the pipe, that is, the open state, vertical is closed.Method two: the valve handle and pipe to "one" word proved to come, into "ten" word is off. Also, turn the handle clockwise and turn counterclockwise.
Q: What's the sewage treatment valve with?
Butterfly valve manufacturers are many, the price is also different, as long as the right can.
Q: Which valves are installed in a directional manner?
Regulating valve, stop valve, eccentric butterfly valve, check valve, one-way valve, solenoid valve, pressure reducing valve, drain valve and drain valve. Needle core valve, V ball valve, part of the ball valve, there is flow.Few. Such as floating ball valve, the central butterfly valve does not flow requirements. In general, if the regular manufacturers of valves, flow direction will indicate the flow of medium, to get the valve can see.
Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
On the valve network to find the best, you can find the valve business in Anhui
