1. Manual Wafer Butterfly Valve Description

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

5.FAQ

 

1. What is manual wafer butterfly valve?

A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.

 

2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

3. What is the working principle of manual wafer butterfly valve?

 A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

 

Q:If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?
the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.
Q:What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q:Why is copper used in cryogenic valves?
Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Q:I would like to ask, how specific treatment, and compared with the industry?.Is there a constructive answer?
I have to do the technical sales colleagues is high inside out now before the inside sales revenue is also good about one hundred thousand a year as sales of a great degree of luck the.I do not know what the specific circumstances, what age, in this line for several years, there is the opportunity to communicate with the landlord and make progress together.
Q:What does the 4 point valve mean?
The caliber is DN15's valve. What valves do you need?
Q:What valve is the YQZ45X-16Q?
Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
Q:What is a lift rod valve?
Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.
Q:What is the valve?
The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.
Q:How big valves are used in the DN90 pipeline?
If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
Q:someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.
