•Emeishan Chicheng Machinery Co., Ltd., located at the world natural cultural heritage, Mt. Emei, abuts Cheng-Kun Railroad. The transportation is very convenient.

•In recent years, our company has held the generating set good market opportunity, promoted the production and marketing level rapidly, and rose with steady steps in the small generating set profession. With the comprehensive strength and obvious enhancement, we have stepped with a high speed development to boldly and gradually go forward.

The pressure relief valve is a long diversion tunnel of a hydropower station safety equipment, general, when the pressure pipeline ΣLV / H greater than 15 ~ 30 hours, to set the surge tank, surge tank civil works due to the amount of larger, longer duration use of pressure regulating valve to replace the surge tank can save investment and shorten the construction period. To royal power plant, for example, saves 90% of investment surge shaft, so that power plants generate electricity for one year in advance. Therefore, the use of pressure regulating valve to replace the surge tank is to save investment and speed up the progress of the works is an important technical measures. Pressure Regulating Valve's role is when the unit load rejection wicket quickly shut down and quickly open the corresponding relief valve at the same time, the unit closed to reduce the flow through the relief valve discharges, standby group and then slowly close the relief valve closed, that is, the installation of pressure regulating valve, the water flow changes the system can slow bone, thereby reducing the pressure on the appreciation of the . On the other hand, since unit is still fast closed, thus ensuring the rate of appreciation will not be too high. Therefore, the pressure regulating valve to reduce pressure on the appreciation of the long water diversion system and crew on the rate of appreciation is one of effective measures in this regard instead of surge shaft played a role.
