Energy-saving lock-type liquid-controlled ball valve features and technical parameters

Accumulator lock-type liquid-controlled ball valve is mainly used in large and medium hydropower stations. Installed in front of the turbine, used as a turbine inlet valve. The upstream is connected with the pressure steel pipe and the downstream is connected with the volute inlet pipe. On the one hand when the turbine or generator to be overhaul; through the valve cut off the flow of water in the pipeline for safe overhaul. On the other hand, when an abnormal situation occurs in the turbine or the generator, the water flow can be cut off quickly and effectively to prevent the accident from occurring.

Solar Panel Profile

Solar photovoltaic module frame refers to the fixed frame of aluminum alloy profiles for photovoltaic solar panel components. Because solar photovoltaic modules must guarantee an outdoor service life of about 25 years, the aluminum frame used in solar photovoltaic modules must have good oxidation resistance and corrosion resistance. Generally, the frames used in solar photovoltaic modules are divided into three types: anodic oxidation, sandblasting oxidation and electrophoretic oxidation.
