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: 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 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: What is the principle of butterfly valve and check valve? Any difference?
- Direct water butterfly valve, check valve is to water can not flow valve
- Q: Water supply pipe gate valve and butterfly valve which good?
- 2. ball valve: ball valve with a central opening of the ball as the valve heart, the rotation of the ball control valve opening and closing. The ball valve has the advantages of simple structure, light weight compared with the cut-off valve, the sealing surface has the advantages of simple structure, easy processing, good sealing performance, convenient operation, switch quickly, but can not be used to adjust the flow, suitable for high pressure (up to 320 psig) pipeline, at present, the packing material limit, can only be used for 200 DEG C, can also be used a variety of media and the viscosity of the suspension.3. butterfly valve: butterfly valve, also known as turn over plate valve, is a simple structure of the valve. As butterfly valve should not be closely matched with the pipe wall, only applicable to regulating flow, can not be used to cut off the pipeline, often used in conveying air and flue gas pipe to regulate flow. Butterfly valve is with the stem rotation of the circular butterfly plate for headstock parts, in order to achieve the opening and closing action of the valve. Butterfly valve is mainly used with shut-off valve, can also be designed to adjust or cut off and adjust the function. At present, butterfly valves are used more and more in low pressure medium and large diameter pipelines.
- 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: Types of butterfly valves
- Butterfly valve structure categories: central to clip butterfly valve, central flange butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, eccentric butterfly valve, soft sealing butterfly valve, hard sealing butterfly valveButterfly drive categories: handle, worm gear, electric, pneumatic, electromagnetic, electromagnetic, hydraulic, electro hydraulic, hydraulic, hydraulic, pneumatic
- Q: What is the butterfly valve
- From the working principle of double butterfly valve can be seen that the operation is simple and easy to use, almost no wearing and maintenance compared with traditional ingredients.
- Q: Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
- 3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.
- Q: The difference between vertical and horizontal butterfly valves in municipal water supply
- Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
- Q: Butterfly valve structure and working principle
- Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
