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:What are mine valves?
You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.
Q:Heating pipes, in addition to the living room,
There is gas, causing water not to cycle, give up on the cure! Are you single family control?Single family control, the general bedroom and living room is not all the way, the living room, this way, the vent valve in the toilet, I was on the road in the balcony! The bleeder valve, is made of copper tube in the device above two, as long as can step in his place, the bleeder valve with a small angle, feet above a needle, with a needle to drill a well, there is a long time not float, a gas exhaust out that leads to water circulation,Why do you put a little while, the water is hot, a little cooler, the water does not cycle, is dead water, can not cool it?I am building plumbing, believe me, yes, these are some common problems, especially on the top floor!
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective. Butterfly valve manufacturers are many, the price is also different, as long as the right can.
Q:What is the normal temperature on the valve?
At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:Valve category can fill the trunk door, branch valve Mody?
Valve category can fill the trunk door, branch valve? "no, too general."
Q:What's the valve specification DN20?
You should be asking, how many inches?DN20 is 3/4
Q:Is the heat jacketed valve fitted with flanged flanges?
Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.
Q:What do you mean by the 16 bit coding of the valve type?
What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one
Q:What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
Q:What's the valve as a unit?
Business now there are many valve manufacturers, with the rapid expansion of SMEs, SMEs are more ~!
