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:So how does the valve turn on?
The handle of the valve is opened along the pipe and perpendicular to the pipe
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating hard sealing electric ball valve is suitable for two cutting and adjusting occasions. Connect the valve and actuator by using direct connection, DCL series miniature electric actuator (also can be configured according to user requirements of the electric actuator or pneumatic piston actuator of different types of electronic components and ultra short ball).
Q:What is a hot melt valve?
The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:What do letters represent in the QF-2 and PX-32 valve models?
This is the material code, specific check: valve code. Just OK
Q:What's the difference between valves and valves without valves?
The advantage of carrying valves and venting valves is that they control the amount of exhaust and prevent other fluids from flowing out.
Q:What are the production equipment in valve shop?
CNC machining center, double control vertical lathe, CNC lathe, CNC machine tools, heavy vertical double column lathe, spherical lathe horizontal boring machine, surface grinder, cylindrical grinder, lathe, milling machine, hydraulic head full bed, gate valve grinding machine, grinding machine, lathe, radial drilling machine,Powder plasma arc welding machine, thyristor rectifier, DC DC arc welding machine, welding machine, drying machine, trolley type resistance furnace, hook type shot blasting machine, medium pressure compressor, crane, pneumatic label printer, printer, compressed air sprayer spraying water line, air pressure box type resistance furnace. Forklift lifting platformLow temperature test equipment, metal and low temperature impact test machine, quantitative spectrometer imported carbon sulfide analyzer, microcomputer analyzer, spectrum analyzer, X-ray flaw detector X-, permeability detector, magnetic particle detector, ultrasonic thickness meter, digital ultrasonic flaw detector, metallographic microscope, hardness tester, precision analysis balance (hydraulic material testing machine), hydraulic valve testing machine hydraulic valve testing machine, submerged valve testing machine, steam trap test machine, valve testing machine, pressure testing machine temperature test machine
Q:Valve legend
F means a pressure gauge or thermometer; as to which type of valve, the marking should be a stop valve.
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:What's the caliber of the valve 1/4?
1 inches is equal to 25.4mm, 1/4 how big, count it yourself.
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
1/2, 1/4 valve is our usual popular name. "1/2" and "1/4" refer to the size of the valve bore, in inches. And there are 3/4, 3/8 to 24, 30, and 36 inches. Relative to our country on the valve bore that is "DN."". There are about 1 inches =25.4MM conversion, so in general we are 1 inches of the valve is DN25 valve.
