Bonded warehouse valve automatic control system integrated with Limitorque actuator

Abstract

The invention discloses a bonded warehouse valve automatic control system integrated with a Limitorque actuator. The bonded warehouse valve automatic control system integrated with the Limitorque actuator comprises a bonded warehouse valve and a control room. The electric bonded warehouse valve is provided with a valve feedback annunciator and an opening / closing valve command device, and the valvefeedback annunciator and the opening / closing valve command device are connected through the Limitorque actuator. The control room is connected with the Limitorque actuator through a cable, and the control room is connected with the valve feedback annunciator and the opening / closing valve command device through cables. The bonded warehouse valve automatic control system integrated with the Limitorque actuator can be electrically / manually operated on field, and the valve can be remotely operated in a central control room; opening or closing in-place information can be accurately displayed, thebonded warehouse valve can be automatically opened or closed, a fault can be displayed in time once the bonded warehouse valve breaks down, and quick maintenance of the bonded warehouse valve is facilitated; and besides, when the bonded warehouse valve breaks down, a hand wheel can be conveniently rotated manually to open or close the bonded warehouse valve, and use is convenient.

Description

technical field [0001] The invention relates to the technical field related to bonded warehouses, in particular to a Limitorque actuator integrated into a bonded warehouse valve automatic control system. Background technique [0002] At present, bonded warehouses refer to warehouses approved by the customs for the storage of imported goods and are not subject to the management of customs laws and import control regulations. Imported goods stored in bonded warehouses can be modified, graded, sampled, Mixing and reprocessing, etc. If these goods are re-exported, they will be exempted from paying tariffs, and if they enter the domestic market, they will be required to pay tariffs. Countries have clear regulations on the storage period of bonded warehouse goods. In addition to providing convenience for traders, the establishment of bonded warehouses It can also promote entrepot trade, so the valves in bonded warehouses play an important role. They can protect the goods inside th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a Limitorque actuator integrated into the bonded warehouse valve automatic control system to solve the general problem in the above background technology that the valve feedback signal line and the open / close valve command line are not connected when the actuator is replaced. , only connect the power cable, and finally lead to remote computer operation in the central control room, unclear valve status, unclear whether the valve is faulty, only on-site electric / manual operation, increasing the working pressure, inconvenient for fully automatic work, inconvenient to use , problems affecting work efficiency
