The working process of the liquid tank ventilation system in the nuclear area of the marine nuclear power platform is as follows: the pressure sensor detects the air pressure value in the liquid tank, when the detected air pressure value exceeds a set range, the control box controls the stop check valve to open, the liquid tank is ventilated to the buffer tank, the pressure in the liquid tank is balanced, and after the pressure in the liquid tank is stable for a period of time, the control box controls the stop check valve to close, and the internal sealing of the liquid tank is kept. When the pressure fluctuation in the liquid tank is overlarge, the quick-closing valve can be closed emergently to protect the safety of the ventilating chamber where the buffer tank is positioned
The invention has the following advantages:
(1) the ventilation system of the cabin in the nuclear area of the marine nuclear power platform can monitor the air pressure in the liquid cabin in real time, and can automatically control ventilation to the buffer tank once the air pressure exceeds a set value.
(2) The quick-closing valve is arranged at the tail end of the ventilation pipeline, so that the safety of the ventilation cabin can be effectively ensured under the accident condition.
(3) The buffer tank can buffer the pressure difference between the liquid cabin and the ventilating cabin, and can load the liquid sprayed out of the liquid cabin due to the pressure difference when the pressure of the liquid cabin is overlarge.
(4) The stop check valve is a core component, can be automatically switched to an open or closed state through pressure sensed by a sensor in the liquid cabin, and is high in intelligence.

Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in figure 1, the liquid tank ventilation system for the nuclear area of the marine nuclear power platform comprises a liquid tank 1, a quick-closing valve 2, a stop check valve 3, a buffer tank 4, a pressure sensor 5, an air pipe 6, a ventilation chamber 7, a handle 8, a steel wire rope 9, a control box 10 and a control pipeline 11, wherein the quick-closing valve 2, the stop check valve 3 and the buffer tank 4 are all located in the ventilation chamber 7.
One end of the air pipe 6 is communicated with the top end of the liquid tank 1, the other end of the air pipe is communicated with the buffer tank 4, the air pipe 6 tends to move upwards from the liquid tank 1 to the buffer tank 4, the horizontal inclination angle of the air pipe 6 is not less than 30 degrees, and otherwise the air pipe 6 is likely to generate a water sealing phenomenon and cannot play a role of ventilation.
The quick-closing valve 2 and the stop check valve 3 are mounted on a section of air pipe 6 inside the air-permeable chamber 7 and are mounted in front of the buffer tank 4 in sequence, i.e. the quick-closing valve 2 is close to the liquid tank 1 and the stop check valve 3 is close to the buffer tank 4. The quick-closing valve 2 is connected with a control handle 8 through a steel wire rope 9, and the quick-closing valve 2 can be opened and closed through the control handle 8.
The control box 10 is connected to the pressure sensor 5, the quick-closing valve 2 and the stop check valve 3 through control lines 11, and the control box 10 can control the opening and closing of the quick-closing valve 2 and the stop check valve 3 according to data acquired by the pressure sensor 5. Normally, the quick-closing valve 2 is in an open state, and in an emergency condition (the inside of the liquid tank 1 is damaged or the ventilation chamber 7 is damaged), the quick-closing valve 2 can be quickly closed through a handle 9 in the ventilation chamber, so that a pipeline between the liquid tank 1 and the ventilation chamber 7 is cut off, and the safety of the two chambers is kept.
When the gas permeable system of the liquid tank in the nuclear area of the marine nuclear power platform works, the stop check valve 3 is in a closed state, when liquid is pumped and poured into the liquid tank 1, the pressure sensor 5 in the liquid tank 1 monitors the pressure of the liquid tank 1, the pressure value is transmitted into the control box 11, and when the pressure exceeds a specified range, the control box 11 sends an instruction to open the stop check valve 3. When the pressure in the liquid tank 1 is increased, the gas in the liquid tank 1 flows to the buffer tank 4 through the air pipe and then flows to the ventilating chamber 7; when the pressure in the liquid tank 1 becomes small, the gas in the ventilating chamber 7 enters the buffer tank 4 and then enters the liquid tank 1 through the air pipe. When the liquid in the liquid tank 1 stops sucking and pouring, and the pressure sensor 5 monitors that the pressure in the liquid tank 1 is stabilized in a specified range for a certain time, the control box 11 sends out an instruction to close the stop check valve 3.
The control box 11 can not only intelligently control the opening and closing of the stop check valve 3 according to the monitoring value of the sensor 5, but also can be manually controlled, and the reliability is higher.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
