Description

Technical Field

[0001] The present invention relates to the technical field related to remote control valves, and in particular to a remote control device in a valve box of a bulk carrier. Background Art

[0002] Remote control valve This valve consists of a main valve and an external pilot valve. It uses the floating ball in the water to link the pilot valve due to the change of the liquid level, so that the main valve can supply water and close, thereby controlling the water level of the pool (tank) and the water tower within a certain range to prevent overflow and low water level. This valve is suitable for the automatic water supply system of various pools (tanks) and water towers in industrial and mining enterprises and civil buildings. It is also used in the circulating water supply system of atmospheric pressure boilers. Therefore, a remote control device in the valve box of a bulk carrier is particularly needed.

[0003] However, the existing remote control device in the valve box of bulk carriers is not controlled by the bulk carriers when in use. The ballast and remote control valves of the cargo hold are arranged in the corresponding valve boxes, but there is no direct passage from the valve box to the main deck. The valve box can only be reached through the cargo hold, which does not meet the relevant ABS specifications. The installation and arrangement of the remote control valve must be able to close and remain closed when the control power source is lost. The alternative design must have a passage to facilitate manual closure when the control power source is lost. If the remote control valve is to be modified or a passage from the valve box to the main deck is to be added, not only a new design is required, but also a lot of cost will be added.
