Share(1) Scene Problems
Electric ventilation butterfly valves are widely used in ventilation and environmental protection projects in industries such as metallurgy, chemicals, building materials, power stations, and glass, for cold or hot gas pipelines containing dust. Common problems in these scenarios include:
1. High-Temperature Expansion: In high-temperature environments, valve components are prone to thermal expansion, which can cause the valve to seize.
2. Sealing Issues: The presence of dust or corrosive gases in the medium can challenge the sealing performance of traditional butterfly valves.
3. Operational Flexibility: In complex industrial environments, valves need to be frequently opened and closed, requiring high flexibility and reliability in operation.
(2) Shanghai Rogers Butterfly Valve Technology and Features
1. Compact Design: The valve features a midline butterfly plate welded to a short-structure steel plate, resulting in a compact and lightweight structure that is easy to install.
2. Double-Eccentric Structure: This design helps the butterfly plate form a self-tightening seal when closed, maintaining good sealing performance under different pressure conditions.
3. High-Temperature and Corrosion Resistance: The valve body and butterfly plate materials are often made of high-temperature and corrosion-resistant materials to meet the special requirements of dust-laden or hot gas pipelines in industries such as metallurgy, building materials, and power stations.
4. Multi-Position Installation: The valve supports multi-position installation and is not restricted by the direction of the medium flow, adapting to various installation environments and operating conditions.
5. Low Leakage Rate: An oil-sealed collar is installed on the valve body, with no visible gaps between the sealing pairs, resulting in a low leakage rate.
(3) Solutions to Pain Points
1. The valve design includes an expansion gap between the butterfly plate and the valve body, effectively preventing seizure caused by thermal expansion and contraction.
2. The double-eccentric structure and diverse sealing materials ensure good sealing performance under different operating conditions.
3. The use of electric actuators makes the opening and closing of the butterfly plate more flexible and convenient, supporting multi-position installation and unrestricted by the direction of the medium flow.
