Abstract
The utility model discloses a manual-automatic control system with a pneumatic double-acting actuator and an air storage tank. The manual-automatic control system comprises a pneumatic double-acting control valve, a manual-automatic control system body and an accident air storage tank. The pneumatic double-acting control valve is composed of a valve and the pneumatic double-acting actuator which are connected mutually, and the manual-automatic control system body comprises a first pneumatic control valve, a second pneumatic control valve, a solenoid valve, a pressure switch, a on-site manual control panel, an air filtration and decompression assembly, a one-way valve, a third pneumatic control valve, a fourth pneumatic control valve and a fifth pneumatic control valve. The control valves can achieve remote control, also can achieve manual control on site, and effectively avoid the phenomenon that due to various faults of an on-site hand wheel device, the valve breaks down. Due to the fact that the accident air storage tank is added in the control system body, valve interlocking action is achieved when control valve air source fault occurs, and the phenomenon that a pneumatic single-acting actuator is adopted for a long time, and therefore the valve can not be opened or closed tightly is avoided.
Description
[technical field]
The utility model relates to the technical field of pneumatic control valve hand automatic control system, is specially adapted to industrial automatic control Large diameter valve or travel time is short and the technical field that needs remote auto control and on-site manual to control.
[background technique]
The on-site manual control of existing pneumatic control valve, major part partly increases handwheel devices at pneumatic actuator and realizes.And handwheel devices generally adopts gear transmission, causes the speed of opening/shutting valve slower.Before the handwheel devices operation, need to confirm that automatic control section switches to manual operation state fully, the process more complicated is often because Field Force's misoperation causes damage.Moreover, because Pneumatic single-action actuator inside with spring, causes when manually-operable, need the site operation personnel to use larger power ability opening/shutting valve.Another part employing carries manually operated import solenoid valve and controls, but is with manually operated solenoid valve price general charged expensive, and the delivery cycle is longer, is not used generally speaking.
