As a final protection for personnel and critical equipment, emergency escape systems are vital in deep sea equipment products. Because the emergency escape system is used during escape, the requirement on the reliability of equipment is high, but the emergency escape system is disposable, the use cost is high, and the reliability of the equipment cannot be guaranteed. Taking the manned equipment as an example, when the manned equipment has an emergency in deep sea, personnel carry important equipment information to enter the escape cabin, and then separate cabin water injection is carried out. Because the separation cabin is not filled with water and has balanced pressure with the external environment, the separation cabin can not be separated under the action of the external pressure. After the pressure of the separation cabin and the external seawater is balanced, the escape system is started to separate the escape cabin, and personnel are carried to the sea surface by the positive buoyancy of the escape cabin. The escape system is not frequently used, has short action time and small energy requirement, and is usually in a form of a prepared power source, namely an energy accumulator; the electromagnetic valve is controlled to be opened and closed, and acts on the oil cylinder to push the escape cabin to be separated. Although the existing electromagnetic valve is mature in technology and high in reliability, the underwater use working condition is complex, various problems cannot be predicted in emergency, and the electromagnetic valve must be isolated from the water environment, so that the sealing technology of the electromagnetic valve is higher in requirement. Because the deep sea equipment belongs to the atmospheric pressure air environment under the non-emergency condition, this also provides higher degree of difficulty to detecting whether sealed inefficacy. Therefore, the high reliability of the escape system cannot be ensured by adopting the electromagnetic valve control.

When the valve core 8 moves to one end, close to the external pressure port 10, in the cavity 14, a channel between the first pressure port 12 and the second pressure port 13, which is communicated with the cavity 14, is blocked by the boss 82, and when the valve core 8 moves to one end, far away from the external pressure port 10, in the cavity 14, a communication channel is formed among the first pressure port 12, the outer surface of the valve core 8 body and the second pressure port 13.
The inflatable structure is as follows: the automatic air-filling device comprises a groove body which is arranged in a rear seat 2 at one end of a cavity B11 and communicated with the cavity B11, wherein an elastic core 7 is arranged inside the groove body, an air charging valve 5 matched with the elastic core 7 is arranged at the opening position of the groove body, and a pore passage 51 communicated with the groove body is arranged in the middle of the air charging valve 5.
The inflation valve 5 is externally provided with a screw cap 6, and the screw cap 6 opens or closes the inlet of the duct 51.
The structure of the elastic core 7 is: the inflation valve comprises a conical head 71, a rod part extends from one side of the head 71, the rod part is connected with a spring 72, the other end of the spring 72 is fixed at the bottom of the groove body, one end of the inflation valve 5 is provided with a groove 52 which is communicated with the hole channel 51 and has a larger section size, and the groove 52 is matched with the head 71 to communicate or separate the hole channel 51 and the cavity B11.

the pressure of the cavity B is detected in real time by the pressure detection element 3. In emergency situations, personnel need to escape, and after entering the escape cabin, the separation cabin is filled with water. When the filling begins, personnel must have entered the escape compartment. Along with the continuous entering of external sea water in the separation cabin, the pressure rises continuously, acts on the valve core 8 through the external pressure port 10, because the right end of the valve core 8 only has gas pressure acting force, the pressure is far less than the sea water pressure, along with the continuous rising of the pressure, the valve core 8 is pushed to move right until the valve core 8 reaches the right end of the rear seat 2, as shown in fig. 3. At the moment, the first pressure oil port 12 is communicated with the second pressure oil port 13, and the high-pressure oil acts on the actuating mechanism, so that the escape chambers are separated. As long as the cavity B11 is ensured not to enter the seawater pressure, even if the valve core 8 is blocked, the valve core is pushed to move rightwards under the action of the external seawater pressure, and the working reliability of the valve is ensured.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
