1. 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.

2.Main Features of the Butterfly Valve 

(1) 90° movement for full open/close position. 

(2) Excellent control characteristics.Tight shut-off even after innumerable operations.

(3) Installation cost considerably reduced because of very low weight and compact design.

(4) Longer life and reliable service with minimum component wear.

(5) Renewable seats. No supplementary gasket required with the adjacent pipework.

(6) Body & Stem totally protected from service fluid.

 5.FAQ

1. What is manual wafer butterfly valve?

 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?

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 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:What is the medium flow rate when the centerline butterfly valve is fully open?
On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
Q:What are the advantages of butterfly valves?
Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
Q:i have a slightly small mitral valve leak in my heart. my cardiologist say nothing to worry about, but i am not sure. can some one explain if it would eventually lead to some complications?
Mitral valve prolapse is the most common cardiac problem and may affect five to twenty percent of the population. The condition is most common in women, although men are also affected. With MVP, symptoms do not begin before the early teenage years (approximately age 14 in girls and 15 in boys), but adults of any age may be affected. MVP tends to run in families, so those with blood relatives with MVP have a greater chance of also having the condition. If a person has mild MVP, he/she needs no restriction of exercise. But if the MVP is big, then it is a different thing. Because, though complications in this condition are very less, people who suffer from this condition have to take extreme care. In case of large MVP, you may have to cut down on your physical activity, have a surgery and may be put you on medications like beta blockers. If the valve is truly defective (not just 'prolapsed'), it is serious. Unfortunately, doctors have mistaken a 'differently shaped' mitral valve as a disease in itself. And this is where the non-disease comes in. In simple terms, a mitral valve that appears prolapsed is usually normal. It still is not clear to experts why some mitral valves appear prolapsed and allow some blood leakage backwards. I have an answer for that phenomenon, but the important point is that the disease is a non-disease.
Q:I am confused as to the answer of this question. Please help.Indicate the status of the mitral, tricuspid and semilunar valves (whether they are open or closd) during the various phases of the cardiac cycle. Discuss the pressure in each of the relevant chambers or blood vessels during the phases with reference to the opening or closing of the valves.
A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (the right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called diastole. The second part of the pumping phase begins when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles, causing them to contract. This is called systole. As the tricuspid and mitral valves shut tight to prevent a back flow of blood, the pulmonary and aortic valves are pushed open. While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body. After blood moves into the pulmonary artery and the aorta, the ventricles relax, and the pulmonary and aortic valves close. The lower pressure in the ventricles causes the tricuspid and mitral valves to open, and the cycle begins again. This series of contractions is repeated over and over again, increasing during times of exertion and decreasing while you are at rest. The heart normally beats about 60 to 80 times a minute when you are at rest, but this can vary. As you get older, your resting heart rate rises. Also, it is usually lower in people who are physically fit.
Q:Why use special flanges for butterfly valves?
Butterfly valve to use special flange, butterfly valve itself is because of the structure of the decision, the butterfly valve to clip type connection, this pair of clamps is a special flange.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
Q:What's the difference between an electric two position control valve and an electric butterfly valve?
With manual control device, once the power failure occurs, you can temporarily manually operated, and will not affect the use.The biggest difference is that the electric double bit butterfly valve can not fine adjustment; and the electric butterfly valve can play a regulating role.
Q:My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech
Q:Fire, the signal butterfly valve flange connection or welding?
1, do a good job with flange.2, flange (Flange), also known as flange, flange plate or edge. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".3, also known as welding: welding, melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology.
Q:What are the uses and classifications of manually operated clip butterfly valves?
Manual to clip butterfly valve use: manual to clip butterfly valve butterfly plate installed in the pipe diameter direction.
Q:Butterfly valve network and ordinary butterfly what is the difference?
Pipeline butterfly valve is turntable upward, like the gate valve, can be installed in the ground, the ordinary turntable is left or right.
