Aluminum alloy double disc shaft lug type butterfly valve

Aluminum alloy double disc shaft lug butterfly valve is a valve used to control the flow of fluid in pipeline systems. It has the characteristics of light weight, high strength and corrosion resistance. The following is a detailed introduction to this butterfly valve:

1. Main components

Aluminum alloy body:

Aluminum alloy material: The valve body is made of aluminum alloy material, which has the characteristics of light weight, high strength and corrosion resistance. It is very suitable for applications that require weight reduction and corrosion resistance.

Double Offset Disc:

Double Offset Disc design: This design allows the valve to form a better seal when closed, reduce wear and extend service life. The structure of the double disc butterfly valve helps to reduce operating torque and improve sealing performance.

Shaft Design:

Double shaft design: The valve adopts a double shaft structure, which can improve the stability and operating accuracy of the valve. The shaft is usually integrally formed with the valve plate or fixed by a reliable connection method to ensure the reliable operation of the valve.

Lug Type Connection:

Lug Type Design: The lug type design allows the valve to be installed and removed in the pipeline system without affecting other parts of the pipeline. It is particularly suitable for systems that require online maintenance.

2. Working Principle

The aluminum alloy double-flap shaft lug butterfly valve drives the valve stem by rotating the handle, turbine or actuator to rotate the double-flap valve plate to control the on and off of the fluid. The double-flap design enables the valve to form a better seal when closed, reducing leakage and wear.

3. Advantages

Lightweight and high strength: Aluminum alloy materials make the valve light and easy to install, while having sufficient strength to withstand working pressure.

Corrosion resistance: Aluminum alloy materials and appropriate surface treatment (such as anodizing) provide excellent corrosion resistance and are suitable for corrosive environments.

Good sealing performance: The double-flap design and high-precision manufacturing process ensure good sealing performance of the valve and reduce leakage.

Easy installation and maintenance: The lug design allows the valve to be independently installed and disassembled in the pipeline system, which is convenient for online maintenance.

Easy operation: Suitable for manual, turbine or automatic actuators, easy and flexible operation.

4. Application scenarios

Aluminum alloy double-flap shaft lug butterfly valve is widely used in the following fields:

Water supply system: used for the switch control of water supply pipelines, it is very suitable due to its corrosion resistance and light weight.

Sewage treatment: Used in sewage treatment plants to control the flow of sewage, corrosion resistance ensures its long-term use in harsh environments.

Chemical industry: Suitable for piping systems with corrosive chemicals, ensuring the reliability and safety of fluid control.

Food and beverage: In food and beverage processing, used to control fluid flow, the safety and corrosion resistance of aluminum alloy materials are important advantages.

HVAC system: Used for fluid control and regulation in heating, ventilation and air conditioning systems.

5. Installation and maintenance

Installation: Make sure the valve is installed in the appropriate position, between the pipe flanges, and fixed with bolts. The lug design allows the valve to be installed independently, ensuring coaxial alignment to ensure sealing performance.

Maintenance: Regularly check the sealing performance and operating flexibility of the valve to ensure no wear and corrosion. The turbine or actuator part should also be lubricated and inspected regularly.

Online maintenance: The lug design facilitates online maintenance and replacement without shutting down or disassembling the pipeline.

Conclusion

The aluminum alloy double-flap shaft lug butterfly valve is a valve with excellent performance and easy operation, especially suitable for industrial applications that require high strength, corrosion resistance and lightweight design. Its compact structure design, easy installation and maintenance make it widely used in water supply, sewage treatment, chemical industry, food and beverage and other fields. It is an ideal choice for fluid control.
