Product Description
Butterfly valve is also known as the flap valve, is a simple structure of the control valve, can be used for the low-pressure pipeline medium switch control butterfly valve is the shutoff (disc or disc) for the disk around the valve shaft rotation to open and close a valve.
Product Application
Applicable occasion
Butterfly valves are suitable for flow control. Because the pressure loss of the butterfly valve in the pipeline is relatively large, the disc should also be considered when closed to withstand the pipeline medium pressure firmness. In addition, consideration must be given to the limits of the working temperature of the elastic seat material at high temperatures. Butterfly valve structure length and the overall height of small, open and close speed, and a good flow control characteristics, butterfly valve structure principle is most suitable for the production of large diameter valve. When the butterfly valve is required to control flow, the most important thing is to choose the correct size and type of the butterfly valve so that it can work properly and effectively.
Generally, in the throttling, regulating control and mud medium, the structure length is required to be short and the opening and closing speed is fast (1/4 turn). Low pressure cut-off (small pressure difference), butterfly valve is recommended.
Butterfly valves can be used when there is a small amount of leakage into the atmosphere due to double-position adjustment, contraction of ground channel, low noise, cavitation and gasification.
When using butterfly valves under special operating conditions, such as throttling regulation, or strict sealing requirements, or severe wear and low temperature (cryogenic), it is necessary to use a special designed metal sealing tape regulating device to use a special butterfly valve with three or double eccentricity.
The butterfly valve is applicable to fresh water, sewage, seawater, salt water, steam, natural gas, food, medicine, oil, various acid and alkali and other pipelines with requirements of complete sealing, zero gas test leakage, higher life requirements and operating temperature of -10 ~150 degrees.
The flexible sealing eccentric butterfly valve is suitable for the bidirectional opening and closing and adjustment of the ventilation and dust removal pipeline. It is widely used in the gas pipeline and water channel of metallurgy, light industry, electric power and petrochemical system.
The double eccentric butterfly valve with metal to wire seal is applicable to the gas, oil, acid and alkali pipelines such as urban heating, gas supply, water supply, etc.
In addition to being used as the program control valve of large pressure swing adsorption (PSA) gas separation device, the tri-eccentric butterfly valve with metal sealing on metal surface can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, and is a good substitute for gate valve and globe valve.
Structural characteristics
1, the butterfly valve has simple structure, small volume, light weight, material consumption province, small installation size, small quick, 90 ° reciprocating rotary switch, low driving torque, etc, used for truncation, connected, regulate medium in pipe has good flow control characteristics and close the sealing performance.
2. The butterfly valve can transport mud with the least amount of liquid at the pipe opening. Good sealing can be achieved under low pressure. Good regulating performance.
3. The streamline design of butterfly plate makes the loss of fluid resistance small, which is a kind of energy saving product.
4. The valve stem is a through rod structure, which has good comprehensive mechanical properties, corrosion resistance and abrasion resistance. When the butterfly valve opens and closes, the valve stem is only used for rotating movement instead of lifting and running. The packing of the valve stem is not easy to damage, and the sealing is reliable. Fixed with disc cone pin, the overhanging end is designed to prevent the stem from collapsing when it accidentally breaks at the connection between stem and disc.
5. Connection mode includes flange connection, clamp connection, butt welding connection and lug clamp connection.
Driving mode includes manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.

Installation and maintenance
1. The disc shall be stopped at the closed position during installation.
2. The open position shall be determined according to the rotation Angle of the adjustment plate.
3. Butterfly valve with bypass valve should be opened before opening.
4. The installation shall be conducted according to the installation instructions of the manufacturer, and the butterfly valve with large weight shall be set on a solid foundation.
Title goes here.
1. Clamp butterfly valve
The disc of the clamp butterfly valve is installed in the diameter direction of the pipe. The valve is fully open.
The wafer butterfly valve is simple in structure, small in size and light in weight. Butterfly valve has elastic seal and metal seal two types of seal. Elastomeric sealing valve, sealing ring can be embedded in the body or attached to the disc around.
2. Flanged butterfly valve
Flanged butterfly valve is vertical plate structure, valve stem is integral metal hard seal valve seal ring is flexible graphite plate and stainless steel plate composite structure, installed on the body, butterfly plate sealing surface surfacing stainless steel. The sealing ring of the soft sealing valve is made of nitrile rubber and installed on the disc.
3. Lug butterfly valve
4. Welding butterfly valve
Welded butterfly valve is a kind of closed type butterfly valve, widely used in building material, metallurgy, mining, power production process such as medium temperature 300 ℃ or less on the pipe nominal pressure of 0.1 Mpa, to connect and open/close or adjusting medium quality.
