emergency opening: when the pressure in the cabin is higher than the set pressure outside the cabin, the sea valve can be automatically opened, and timely pressure relief is realized so as to ensure that the cabin structure is not damaged. The concrete introduction is as follows:

in an embodiment of the automatic opening and closing sea valve, externally supplied compressed air fills a valve core cylinder 26 through a connector 3 via a piston flow air hole 27 to push a valve core to move against the spring force of a spring 9, so that a valve core opening 22 of the valve core 8 is opposite to a valve body opening 21, and sea water flows in or out from the valve body opening 21, the valve core opening 22 and a spring frame plate hollow 23 through the sea valve.

Here, as shown in fig. 4, when the sea valve is actively opened, the sea valve is opened in an opened state: the externally supplied compressed air fills the valve core cylinder 26 through the connector 3 by the piston flow air hole 27 to push the valve core to move against the spring force of the spring 9, so that the valve core notch 22 of the valve core 8 is aligned with the valve body notch 21, and the sea valve opens sea water to flow in or out from the valve body notch 21, the valve core notch 22 and the spring frame plate hollow 23; when the externally supplied compressed air is cut off and exhausted, the valve core 8 is restored to be in a fitting state with the bottom of the valve body 1 under the action of the spring 9, and the barrel body of the valve core 8 covers the valve body opening 21 of the valve body 2, so that the sea valve is in a closed state.

In an embodiment of the automatic opening and closing sea valve, when the sea valve is in a closed state, the pressure in the hull acts on the bottom surface of the barrel of the valve core 8 through the valve bottom hollowed-out part 20, when the acting force is larger than the compression force of the spring 9, the valve core 8 overcomes the spring force to compress the spring 9 under the action of the pressure in the hull to move the valve core 8, the valve core opening 22 is gradually opposite to the valve body opening 21, and the sea water gradually opens and flows out from the valve body opening 21, the valve core opening 22 and the spring frame plate hollowed-out part 23: when the acting force is smaller than the compression force of the spring 9, the valve core 8 is under the action of the spring force, the barrel body of the valve core 8 gradually covers the valve body notch 21, and the sea valve is closed.

Here, as shown in fig. 4, when the sea valve is opened, the sea valve is automatically opened: when the sea valve is in a closed state, the pressure in the ship body acts on the bottom surface of the barrel body of the valve core 8 through the valve bottom hollowed-out part 20, when the pressure is larger than the compression force of the spring 9, the valve core 8 overcomes the spring force to compress the spring 9 under the action of the pressure in the ship body so as to move the valve core 8, the valve core notch 22 is gradually aligned with the valve body notch 21, and the sea valve gradually opens sea water to flow out from the valve body notch 21, the valve core notch 22 and the spring frame plate hollowed-out part 23: when the acting force is smaller than the compression force of the spring 9, the valve core 8 returns under the action of the spring force, the barrel body of the valve core 8 gradually covers the valve body notch 21, and the sea valve is closed.

In one embodiment of the automatically openable sea valve of the present utility model, the sea valve further comprises:

a sensor holder 6 mounted on the back of the bottom of the valve body 1;

a sensor 7 mounted on the sensor frame 6 for detecting opening and closing of the valve cartridge;

and a signal block 10 arranged at the bottom of the valve core 8, wherein the signal block 10 is matched with the sensor 7 to detect that the valve core notch 22 and the valve body notch 21 are staggered or opposite.

In one embodiment of the automatically openable sea valve of the present utility model, the sensor 7 comprises: an on detection sensor and an off detection sensor, wherein,

when the valve core notch 22 is aligned with the valve body notch 21, the signal block 10 is contacted with the opening detection sensor, and the opening detection sensor detects that the signal block outputs an opening signal in place;

when the valve core notch 22 and the valve body notch 21 are completely staggered, the signal block 10 is in contact with the closing detection sensor, and the Guan Jiance sensor detects that the signal block outputs a closing signal.

Specifically, when the sea going device is actively opened (normally opened):

when the normal opening function is realized, 3.5MPa medium pressure air is provided on the boat, so that the cylinder of the sea-going device pushes the valve core to overcome the friction force and the spring force to move outwards, the valve core opening is opposite to the valve body opening, the ballast water tank is communicated with the outside of the tank, at the moment, water can be absorbed into the tank through the sea-going device or discharged to the outside of the tank, and when the valve core is opened in place, the opening detection sensor detects the signal block and outputs an opening signal.

After the pressure relief and the air leakage of the cylinder, the spring force pushes the valve core to overcome the friction force so as to enable the valve core to move inwards for resetting, the valve core shields the opening of the valve body so as to enable the sea device to be closed, and when the valve core is closed in place, the closing detection sensor detects the signal block to output a closing signal.

When the sea device is opened passively (emergency opening):

when the sea device is closed underwater, the hydraulic pressure in the liquid tank acts on the inner side end surface of the valve core, and the valve closing detection sensor detects the signal block and outputs a closing signal when the valve is closed. When the water pressure in the cabin exceeds the pressure of the water outside the cabin and overcomes the pressure of the spring on the valve core and the friction force between the valve core and the valve body and between the valve core and the piston of the air cylinder (the pressure difference between the inner side and the outer side is more than 0.04MPa, and the test adjustment determines that the valve core moves outwards), the opening of the valve core and the opening of the valve body are gradually crossed to enable the inside and the outside of the cabin to be communicated, the water in the cabin is discharged outside the cabin under the action of the pressure, the closing detection sensor cannot detect a signal block, and the closing signal is absent. When the pressure difference between the inside and the outside of the cabin is more than 0.045MPa (determined by a test), the valve core opening is completely communicated with the valve body opening, the opening detection sensor detects a signal block, and an opening signal is output.

When the pressure difference between the inside and the outside of the cabin is less than 0.02MPa (determined by a test), the spring force pushes the valve core to overcome the friction force so as to enable the valve core to move inwards for resetting, the barrel body of the valve core shields the opening of the valve body so as to enable the sea-through device to be closed, and when the valve core is closed in place, the closing detection sensor detects the signal block and outputs a closing signal.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
