Pneumatic valve hydraulic control check eccentric hemisphere product features, technical parameters

pneumatic valve hydraulic control check eccentric hemisphere product introduction:
pneumatic valve hydraulic control check eccentric hemisphere series products are widely used in water conservancy, thermal power, water supply and drainage, chemical, metallurgical and other kinds of pump station.
pneumatic valve hydraulic control check eccentric hemisphere series product design, reasonable structure, high strength, no vibration under high velocity. Will be effected according to the program open, when open the port completely open, small water damage at run time, power outages, Or electricity) Automatically according to preset time and point of view, fast, slow close two stages is shut, applicable to spray water, sea water, oil, coal, coke oven gas, dust, gas, etc, can be in export or pipeline pump start-stop back and stop function.
this series pneumatic valves with stable performance, safe and reliable, complete functions, high degree of automation, simple structure, small flow resistance coefficient, etc. The hydraulic system has perfect and reliable intelligent electrical control system, as well as on-site operation, also can remote operation, can be controlled by a central computer for centralized management, and the water pump and other pipeline equipment to realize linkage operation control. When oil pump set or losing electricity failure, shake hand pump can still pneumatic valve open or close the pneumatic valve.
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. 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; In the process of the pneumatic valve is opened or closed, pneumatic valve seat and the spherical cap without rubbing against each other, pneumatic valve life long; Pneumatic valve opens close is not affected by mud and debris, apply to the mud water condition; Use a metal and nonmetal sealing, since the sealing good, water pressure, the greater the sealing pressure, the greater the also; 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 length; There is a clear opening instructions and the adjusting mechanism for the mechanical limit, travel switch device, waterproof and dustproof design is not exposed, 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.
