Hydraulic control slow closing check butterfly valve is an advanced pipeline control equipment at home and abroad. It is mainly installed at the inlet of hydraulic turbine of hydropower station and used as the inlet valve of water turbine; or it is installed at the outlet of water conservancy, electric power, water supply and drainage pump stations to replace check valve and gate valve. When working, the valve cooperates with the main engine of the pipeline. According to the principle of hydraulic transition process, through the effective setting of the electro-hydraulic control program, the reliable cut-off of the pipeline can be realized, the water hammer in the pipeline can be effectively eliminated, and the valve can be automatically closed without electricity, which plays a role in protecting the safety of the pipeline system. The intelligent heavy hammer hydraulic control slow closing check butterfly valve produced by industrial opening valve takes the potential energy of heavy hammer as the power source for automatic valve closing, It adopts PLC intelligent control system, and can install manual and automatic locking device according to user's requirements. It has small flow resistance coefficient, high degree of automation, complete functions, stable and reliable performance. It is based on the extensive collection, research and summary of the performance of similar products at home and abroad, and introduces a number of research results of valve, hydraulic, electrical and other industries, which is developed with thick accumulation and thin development A new generation of intelligent, efficient and energy-saving products.
