Harbin News Network News (Wang Zhongxiao Song Ya Ping, Wang Fangfan) With only one large cylinder valve can be completed in the past need to build a plant and install the appropriate equipment to complete the work. Recently, Harbin Electric Machinery Factory Co., Ltd. independent research and development designed and manufactured the first domestic turbine turbine power station unit, passed the national appraisal. According to reports, the power station turbine valve is a power station unit valve, the main role is to stop the unit when the unit shutdown or overhaul to maintain water. In the past, dome valves or butterfly valves were mainly used in China to accomplish the above tasks. In the course of their use, it is not only difficult to seal, but also requires the construction of a large specialized workshop with a large area and a poor water blocking effect. This time, Haval's self-developed cylinder valve can be nested in power station units. Compared with other types of hydropower unit valves, it has the advantages of reducing processing difficulty, saving materials, good safety and saving plant sites, and is suitable for large-scale Power station needs. It is understood that Kazakhstan's first power station turbine valve will be used for light hydropower station, located in Guizhou Province, Guanling County and Qinglong County at the junction of the northern plateau in the middle reaches of the Beipan River is the leading cascade power station. A total of 4 units were installed in the power station. Harbin Electric signed a construction contract with Guizhou Beipanjiang Hydropower Development Co., Ltd. in June 2004 for 4 units of the Photovoltaic Project.
