Hydraulic control slow close check butterfly pneumatic valve working principle and characteristics

hydraulic control slow close check butterfly pneumatic valve series products are widely used in water conservancy, thermal power, water supply and drainage, chemical, metallurgical and other kinds of pump station. Mainly installed in the pump outlet, alternative to check the function of the pneumatic valve and gate valve. Cooperate with pumps, pneumatic valve, according to the preset program, fast shut gentle closed two stages close the pneumatic valve, effectively eliminate and restrain pipeline water hammer, is to ensure that the water pump unit and the ideal equipment of safe and reliable operation of the pipeline network system.
this series pneumatic valve hydraulic station and electric control box and pneumatic body separation installation, to the nearest can couplet of the installation. Pneumatic valve can be installed in horizontal and vertical.
this series pneumatic valves according to the energy storage mode can be divided into two categories, accumulator and a heavy hammer.
this series product is also called: 'hydraulic control check butterfly pneumatic valve, hydraulic control check pneumatic valve, hydraulic control slow closing butterfly valve, pneumatic valve hydraulic control butterfly', etc. Could replace the water pump export by the pneumatic valve and check valve, and integrating machine, electricity, liquid, cover an area of an area small. A high degree of automation, local and remote and linkage control. Electrical system can be used PLC intelligent control system, also can use ordinary relay system. Hydraulic system of the motor power is small, high efficiency, pressure maintaining performance is good, the oil pump start-up time interval is long. Hydraulic system with functions of automatic pressure maintaining, the holding time is long, the oil pump start to hours. Have clear opening instructions and the adjusting mechanism for the mechanical limit, stroke unit waterproof and dustproof design, stable performance and long service life. Electrical interface humanization, diversification, can design the general push button, text type, touch type, can also according to the needs of customers, design the latest human-computer interface.

hydraulic controlled pneumatic valve is more advanced pipeline control equipment at home and abroad, mainly installed in the hydraulic turbine imports, used as a water turbine imported pneumatic valve; Or installed in water conservancy, electric power, water supply and drainage and other kinds of pumping station pumps export, alternative to check the function of the pneumatic valve and gate valve. Work, pneumatic valve and pipeline host to cooperate, in accordance with the principle of the transient process of water through the preset opening and closing procedures, effectively eliminate the pipeline water hammer, realize reliable cutoff of piping, play a role to protect the safety of pipeline system.
