Butterfly valve, also called the flap valve is a kind of simple structure of the regulator,
also can be used in low pressure pipeline medium valve butterfly valve in the switch
control the way work is closed a (disc or disc) is a disk, around the axis of rotation to
achieve a valve open and close, mainly in the line cut off and throttling effect.
Butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotation
around its own axis, so as to achieve the aim of opening and closing or adjust.
Introduction to the
Butterfly valve, butterfly valve) : also called butterfly valve worm gear
Definition: open-close part for disc butterfly plate and a valve body axis rotate.[1]
Structure: mainly by the valve body, valve stem, disc and seal ring.The body is
cylindrical, short axial length, built-in butterfly plate.
Using range
Electric butterfly valve butterfly valve is suitable for the generator, gas,
natural gas, liquefied petroleum gas, city gas, cold hot air smelting, chemical
industry and power generation, environmental protection, such as, building
water supply and drainage engineering system of conveying a variety of corrosive,
non corrosive fluid pipe, used to adjust and block the flow of the medium.
Functional purposes
Pneumatic butterfly valve butterfly valve (English: butterfly valve) is to point
to shut down a (disc or disc) is a disk, around the axis of rotation to achieve
a valve open and close, mainly in the line cut off and throttling effect.Butterfly
valve opening and closing is a disc-shaped butterfly plate, the body rotation around
its own axis, so as to achieve the aim of opening and closing or adjust.Butterfly valve
fully open to the barrier is usually less than 90 °, butterfly valve and the adjustment
lever itself has no self-locking ability, in order to butterfly plate positioning, to add
worm gear reducer on the valve stem.The use of worm gear reducer, can not only
make the butterfly plate with self-locking ability, make the butterfly plate to stop at
any position, also can improve the performance of the valve.Industrial specialized
characteristic ability of high temperature butterfly valve, apply pressure range is higher also,
nominal valve size is big, the body is made of carbon steel, valve plate seal using metal ring
instead of rubber ring.Large high temperature butterfly valve USES the steel plate welding
manufacturing, mainly for the duct smoke and gas of high temperature medium.
- Q: The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
- Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- Just drive differently,Handle butterfly valve is generally small caliber, because generally small caliber torque smaller, can be directly opened and closed by handTurbine butterfly gear box drive stem rotation.The selection principle for when the stem torque is greater than 300N.M when used in gear box drive gear box, and use the handwheel control hand wheel force is not greater than 300 nm.
- Q: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
- It maybe the valve for your Ice maker / refrigerator or it maybe for the dishwasher. You should be able to look and see where the pipes go. If there is no pipe connected to the valve then it may be there in case you want to install an ice maker or dishwasher. Don't mess with it unless you know what you are doing. Valves like that can start to leak if you go messing with them. Especially if the valves are old.
- Q: The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
- Q: Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.
- every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
- 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.
