Abstract

The invention discloses a pressure difference control device in a closed cabin, the device comprises a pressure difference control module, a cabin pressure monitoring module, a regional pressure monitoring box, a superior monitoring console, a centralized ventilation closing device, a centralized ventilation prevention isolation control device and a sensor group. The pressure control module comprises an overpressure control valve, an overpressure control box, a micro pressure difference control valve and an overpressure safety release valve, the pressure control module is electrically connected with the regional pressure monitoring box, one end of the overpressure control valve is connected with an air pipe, the other end of the overpressure control valve is fixedly connected with the outer wall of a cabin, one end of the overpressure safety release valve is fixedly connected with the cabin wall, and one end of the micro pressure difference control valve is fixedly connected with the cabin wall. The control device and the micro pressure difference control valve monitor and regulate the overpressure between cabins, and the cabin pressure monitoring module and the pressure control module monitor the pressure inside and outside the cabins, feed back information to the superior monitoring console, receive a pressure regulation command transmitted by the superior monitoring console and regulate the pressure inside the cabins.

Description

technical field [0001] The invention relates to the technical field of cabin pressure difference control, in particular to a pressure difference control device in a closed cabin. Background technique [0002] The cabin refers to the various spaces below the deck, including the bow cabin, stern cabin, cargo hold, machine room and boiler room. It needs to be changed to maintain the normal pressure difference between the inside and outside of the cabin. Otherwise, the cabin will be deformed and the danger will be high. The existing cabin pressure adjustment control device is inaccurate in pressure monitoring and unstable in regulation and control, resulting in overpressure between the cabins. [0003] In view of the above-mentioned existing problems, a pressure difference control device in an airtight cabin is now designed. Contents of the invention [0004] The object of the present invention is to provide a pressure difference control device in a closed cabin to solve the ...
