Manual control valve and manual valve is mainly used for the sale of city central heating project of cogeneration power plant. The circulating water pipe network and the refrigeration and air conditioning engineering, with cut-off, throttling and regulating function can replace the throttle orifice, is a throttling device, a variable aperture of the medium temperature: less than or equal to 425 DEG C.
1, improve the supply conditions: all adopt the extension and heat point manual control valve can be according to the design conditions for flow control, the temperature reached in good working condition, the valve gate valve, globe valve is good regulating performance, it has an approximate linear adjustment performance. Therefore, the heating and cooling of buildings are not a strong improvement in the phenomenon
2, to save energy: heat pipe network due to temperature and pressure imbalance, resulting in some branch flow is too large, so that some of the building temperature is too high, the user has to open the window, to achieve the purpose of energy saving
3, improve the management of the hydraulic conditions: manual control valve can be controlled according to the rated flow, the management operation of the excess flow is reduced, so that the original water condition deterioration degree can be improved
