[0002] The flow regulating valve is also known as the self-operated flow control valve, flow balancing valve, and static balancing valve. It is an intuitive and simple flow regulating control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water. No matter how the system pressure changes, the set flow rate is maintained unchanged. These functions of the valve enable the pipeline network flow regulation to be completed at one time, turning the network adjustment work into a simple flow distribution, and effectively solving the hydraulic imbalance of the pipeline network.

This utility model is suitable for regulating the intake flow of the steam turbine in a high-temperature and high-pressure civil steam turbine generator set.

[0004] However, the heat dissipation effect of existing high-temperature and high-pressure flow regulating valves is mostly limited. Usually, a heat sink is set on the surface of the valve body, which is not convenient for actively assisting the heat dissipation of the valve body. The heat dissipation efficiency is limited, and the heat dissipation parts of most valve bodies will generate a large amount of heat. When the staff accidentally touch the heat dissipation parts, they are prone to burns, which is inconvenient for users. Utility Model Content
