In order to achieve the purpose, the technical scheme of the invention is to design a state remote control indicating system for nitrogen gas cargo inlet valves of a chemical carrier, which comprises a cargo control platform, wherein an input module for receiving a switch signal of each valve is arranged in the cargo control platform, a display screen for displaying the opening, closing and intermediate states of each valve is also arranged in the cargo control platform, the display screen is electrically connected with the input module, limit switches are arranged at the full-opening position and the full-closing position of each valve, and the limit switches are electrically connected with the input module. According to actual conditions, a display screen is installed on a goods control platform of a control station for displaying the opening, closing and intermediate states of each valve, an input module is installed in the goods control platform for receiving the switching signals of each valve, each valve provides a limit switch at the positions of full opening and full closing, and the intermediate states are displayed on the display screen through logical judgment by the system.

The technical scheme is that twelve groups of indicator lamps are arranged on the display screen, each group of indicator lamps corresponds to one valve respectively, each group of indicator lamps is provided with three indicator lamps with different colors respectively, and the three indicator lamps with different colors represent the full-open state, the full-closed state and the intermediate state of the valves respectively. Correspondingly, the input module is provided with twenty-four interfaces respectively used for receiving switch signals of twenty-four valves (for example, the input module is used by the applicant for receiving an opening signal and a closing signal of a (left) nitrogen valve of a #1 cargo oil tank, an opening signal and a closing signal of a (right) nitrogen valve of the #1 cargo oil tank, an opening signal and a closing signal of a (left) nitrogen valve of a #2 cargo oil tank, an opening signal and a closing signal of a (right) nitrogen valve of the #2 cargo oil tank, an opening signal and a closing signal of a … … left nitrogen valve of the #10 cargo oil tank, an opening signal and a closing signal of a (right) nitrogen valve of the #10 cargo oil tank, an opening signal and a closing signal of a (left) nitrogen valve of a dirty oil tank, and an opening signal and a closing signal of a (right) nitrogen valve.

The technical scheme is that the valve comprises a valve body, a valve core is arranged in the valve body in a rotating mode, the upper end of the valve core is fixedly connected with a valve rotating along with the valve core, an indicating plate is fixedly arranged at the end of the valve, the upper surface of the indicating plate is attached to a reflective tape with three different colors, a baffle is fixedly connected to the upper end of the valve body and located above the indicating plate, and notches for acting an observation window are respectively arranged at the positions, located at the full-opening position of the valve, at the full-closing position of the valve and at the middle position of the valve, on the baffle. Thus, the valve in the remote control indicating system for indicating the state of the nitrogen gas entering the cargo hold valve of the chemical ship is consistent with the display at the display screen, for example, the proposal used by the applicant is that the full-off state, the intermediate state and the full-on state are respectively indicated at the display screen by red, yellow and green three-color indicating lamps, the three-color reflective tape is also adopted on the indicator plate of the valve, and the arrangement of the notch on the baffle is matched, when the valve is fully closed, the red reflecting belt is exposed at the notch, and when the valve is in the middle state, the yellow reflecting belt is exposed at the other notch of the baffle, therefore, if the indicator lamp has a problem or a maintenance worker regularly overhauls the indicator lamp, the worker-friend interphone at the display screen end can directly inform the corresponding indicator lamp of the current indicating condition, if the indication condition of the indicator lamp is different from the indication of the indicator plate at the valve, which indicator lamp indicates the error can be immediately checked out, so that the checking time and the time before maintenance are saved.

The invention also provides a technical scheme that the indicating method of the state remote control indicating system using the chemical ship nitrogen gas inlet cargo hold valve comprises the following steps: the limit switch at the full-open position or the limit switch at the full-close position of each valve is touched to send a signal to the input module, and the display screen displays a corresponding indicator light through the signal received by the input module; the intermediate state is displayed on the display screen after being logically judged by the input module.

The invention has the advantages and beneficial effects that: the valve in the remote control indicating system for the state of the nitrogen gas inlet cargo tank valve of the chemical ship is consistent with the display at the display screen, for example, the proposal used by the applicant is that the full-off state, the intermediate state and the full-on state are respectively indicated at the display screen by red, yellow and green indicator lamps, the three-color reflective tape is also adopted on the indicator plate of the valve, and the arrangement of the notch on the baffle is matched, when the valve is fully closed, the red reflecting belt is exposed at the notch, and when the valve is in the middle state, the yellow reflecting belt is exposed at the other notch of the baffle, therefore, if the indicator lamp has a problem or a maintenance worker regularly overhauls the indicator lamp, the worker-friend interphone at the display screen end can directly inform the corresponding indicator lamp of the current indicating condition, if the indication condition of the indicator lamp is different from the indication of the indicator plate at the valve, which indicator lamp indicates the error can be immediately checked out, so that the checking time and the time before maintenance are saved. The inspection is convenient, the condition that the indication lamp indicates incorrectly can be found in time, and an inspector can conveniently determine which indication lamp indicates incorrectly according to the indication at the valve, so that the time for inspection and troubleshooting is saved; the invention can effectively reduce the cost and has clear state indication. The use advantages of the electrical control are: the cost can be effectively reduced, and the state indication is clear.
