Fluid control valve is an important safety component engineering, it is through closing fluid countercurrent to ensure directional flow of fluid, which protects other fluid machinery and pipeline safety. Therefore, in the nuclear power plant hydraulic system has been widely used in a variety of non-return valve, such as swing check valves. Swing check valve has a disc-type plug hinged on the edge, through the back off.

Including the design parameters valve series,
Lives industrial power systems, most of the load will produce reactive power, not only affects the operation of the equipment, while the pollution caused by the power grid, power quality seriously affected. Based on the introduction of a variety of
Stainless steel needle valve on the way to rolling mills, electric arc furnace, electric railway and frequency induction furnace and other readily produce large amounts of
Valve manifolds , voltage flicker and three-phase unbalanced load of industrial object of study, high-pressure static reactive power compensation device with valve assembly of key technologies, including tandem valve design parameters, low pulse forming plate (VBE) and high pressure final stage trigger plate (TE) circuit design as well as between them design of optical fiber communication channels. Series of high voltage thyristor valve design for the transformer secondary voltage rating of 10kV power users. Low pulse forming circuit boards using high-performance three-phase thyristor phase-shift trigger pulse forming integrated circuit as the core, the phase voltage signal synchronous voltage signal is compared with the power factor controller has issued a six-way pulse trigger signal formed by to control the working status of high-voltage thyristor.
