In general, combat submarines are equipped with weapons such as torpedoes, missiles, and mines for attacking enemy ships or enemy submarines, and are launched by various launch systems.

The weapon launch method can be largely divided into a swim out method that leaves the launch tube with the propulsion of the weapon itself and a positive discharge method that pushes the weapon from a submarine. Among them, the forced firing method is divided into direct air, water ram system, and air turbine pump system.

Among them, the water ram method is a method of launching an ordnance by supplying water in a cylinder to a launch tube with a piston driven by hydraulic or pneumatic pressure.

Among the weapon launching methods, the water ram method is a method in which a piston driven by hydraulic or pneumatic pressure supplies water in a cylinder to a launching tube to launch an ordnance in a forced ejection method. In general, a process of filling a launch tube with seawater first and draining the filled launch tube after launching an armament is required for launching an armament.

1 is a view schematically showing an opening/closing valve for an intermediate waterway of an underwater weapon launch tube and an ordnance firing method using the same according to the present invention, and FIG. 2 is a view showing a state in which the opening/closing valve is operated in FIG. 1 to launch ordnance, 3 is an exploded perspective view of the opening and closing valve of the intermediate channel of the submarine armed launch tube.

Referring to FIGS. 1 to 3, in the intermediate waterway opening and closing valve of the submarine armed launch tube of the present invention, one forced injection device 220 and a plurality of launch tubes 210 are connected, and a selective one of the launch tubes 210 is connected. It relates to an on-off valve provided in the middle of the launch tube 210 to open and close the channel of the launch tube 210.

Specifically, the underwater vessel launch tube intermediate waterway opening/closing valve 100 is coupled to the outer surface of the launch tube 210, and has two or more first through holes 111 at positions corresponding to the waterway inlet holes of the launch tube 210. ) is formed and the rotor 120 coupled to the outside of the stator 110 and configured to rotate, and having a second through hole 121 formed at a position corresponding to the first through hole 111 consists of The stator 110 and the rotor 120 are formed in a cylindrical shape, and first and second through holes 111 and 121 are formed in the middle portion. As shown in the drawing, six through holes are formed at equal intervals, and when the first and second through holes 111 and 121 match while the rotor 120 rotates in the forward or reverse direction, the valve is opened. , the valve is configured to be closed when each through hole is in a position adjacent to each other by crossing each other. In addition, bearings 113 are coupled to both ends of the stator 110 so that the rotor 120 can rotate smoothly without interference by the bearings 113 . Detailed operations of the stator 110 and the rotor 120 will be described below.

On the other hand, the rotor 120 has two or more rotor blades 122 protruding toward the center at one end of its inner surface, and the stator 11 has a certain angle when the rotor 120 is rotated. A limiting member 112 is formed to prevent the progress of the rotor blade 122 from being abnormally rotated. That is, the rotor blade 122 is formed in a + shape as shown in the drawing, and the limiting member 112 is configured to accommodate protrusions on both sides of the rotor blade 122. For example, the rotor blade 122 and the limiting member 112 are coupled to each other in a form of tooth coupling.

Here, although the first and second through holes 111 and 121 and the rotor blade 122 are shown as six in the figure, they can be appropriately adjusted according to the size of the launch tube. Therefore, the stator 110 and the rotor 120 are configured to rotate in a range of about 60 degrees.

Meanwhile, a driving means 130 for rotating the rotor 120 may be further provided between the limiting members 112 . The driving means 130 rotates the rotor 120 by any one of a rotary motor, a battery, pneumatic or hydraulic pressure, or an electromagnet.

Then, when the driving means 130 is driven after the pressure of the tube 140 is released, the rotor 120 rotates in the forward direction as shown in FIG. located and connected.

Then, when the first and second through holes 111 and 121 are at the same position, as shown in FIG. 2, sea water flows in and the weapon 230 is fired by the forced ejection device.

When the launch of the armament 230 is completed in this way, the front end of the launch tube 210 is closed, and the seawater introduced into the launch tube is discharged back to the sea. After that, as shown in FIG. 5, the driving means 130 rotates the rotor 120 in the opposite direction so that the first through hole 111 and the second through hole 112 are positioned at staggered positions, As shown in FIG. 6, air pressure is applied to the tube 140 to inflate it, thereby blocking the gap between the stator 110 and the rotor 120, thereby maintaining airtightness.

As described above, when the waterway is opened and closed by the rotation of the rotor 120, the pressure of the tube 140 is released, so the stator 110 and the rotor 120 are completely separated and operate without interfering with each other. will do In this way, the interposition of the tube 140 is advantageous in wear resistance, and mechanically always rotates the same position in the forward or reverse direction, so that there is no risk of the stator 110 and the rotor 120 being eccentric. In addition, since pneumatic pressure is applied to the tube 140 after the waterway is closed, airtightness is much better than that of the previously used sealing member.
