Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature pneumatic butterfly valves, in particular to a high-temperature pneumatic butterfly valve with an extended valve stem and a heat sink. Background Art

[0002] Pneumatic butterfly valves, as a common fluid control device, are widely used in industries such as chemical, petroleum, and electric power. Traditional pneumatic butterfly valves feature a simple design and effectively enable opening, closing, and regulating the flow of fluids. However, with increasing demands on industrial equipment performance, pneumatic butterfly valves, particularly those operating in high-temperature environments, require higher temperature resistance and stability. This not only helps extend the life of the equipment but also ensures safe and reliable process operation.

[0003] However, the existing high-temperature butterfly valve plate is prone to deformation due to high temperature, and some pneumatic high-temperature butterfly valves have short valve stems and poor heat dissipation. The heat on the valve body is more easily transferred to the cylinder and solenoid valve and other control components, which can easily cause damage to the control components. Therefore, the temperature for which it is applicable should not be too high.

[0004] Therefore, how to effectively ensure that the pneumatic butterfly valve can operate stably in a high temperature environment has become a technical problem that needs to be solved urgently. Utility Model Content

[0017] Preferably, the heat sink is fixed to the bracket by welding, and the heat sinks on the bracket are evenly distributed to ensure heat dissipation effect.

[0018] By adopting the above technical solution, the heat sink is fixed to the bracket by welding during use, ensuring a firm connection between the heat sink and the bracket and improving structural stability.
