Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable and shutting valve for a submersible gun,

More particularly, the present invention relates to a method for launching an armed weapon through an intermediate water channel of an underwater armed launch tube with high water pressure, And more particularly, to a middle water channel opening / closing valve having a durability and a mooring method using the same.

Generally, combat submarines are equipped with armed forces such as torpedoes, missiles, and mines for attacking enemy ships or enemy submarines, and they are launched by various launch systems.

The armed firing method can be divided into the swim out, which departs from the launch tube, and the positive discharge, which pushes the armed forces in the submarine. Among them, the forced fire method is divided into Direct Air, Water Ram System and Air Turbine Pump System.

Among them, the water ram system is a piston driven by hydraulic pressure or pneumatic pressure, and the water in the cylinder is supplied to the tube to emit the armed force.

Of these, the water ram system is a hydraulic or pneumatic piston, which supplies water in the cylinder to the launching tube and emits the weapon in a forced injection mode. Generally, for launching the armed forces, it is necessary to add the launching tube to the seawater first, and then to discharge the attached tube after the arming.

Thus, in the case of a forced-injection type launch tube, one forced injection system and a plurality of tubes are connected. Therefore, a valve capable of selectively opening and closing the channel in the tube is required. Although it is possible to open and close the middle of the tube in a variety of ways, it is necessary to withstand high water pressure, especially a valve that takes into account the airtightness and stability of the tube.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings, and a method for opening and closing the intermediate water valve and a method for opening and closing the middle water pipe using the middle water pipe of the present invention will be described in detail.

FIG. 1 is a schematic view of an open water shutoff valve and an armed firing method using the same according to the present invention. FIG. 2 is a view showing a state in which an open / close valve is operated in FIG. 3 is a disassembled perspective view of the middle-water shut-off valve of the underwater armed bullet tube.

1 to 3, the water-humid fire tube middle water passage opening / closing valve of the present invention includes a single forced injection device 220 and a plurality of tubular pipes 210 connected to each other, Closing valve provided in the middle of the pouring tube 210 to open and close the channel of the pouring tube 210.

Specifically, the underwater arming tube middle pipe 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 a position corresponding to the inflow hole of the launch tube 210 And a rotor 120 having a second through hole 121 formed at a position corresponding to the first through hole 111. The second through hole 121 is formed in the stator 110, . The stator 110 and the rotor 120 are formed in a cylindrical shape and the first and second through holes 111 and 121 are formed in the middle portion. As shown in the figure, six holes are formed at equal intervals. When the rotor 120 rotates in the forward or reverse direction and the first and second through holes 111 and 121 coincide with each other, the valve is opened , And the valve is closed when the through holes are staggered to each other. A bearing 113 is coupled to both ends of the stator 110 to allow the rotor 120 to smoothly rotate without interference by the bearing 113. [ The specific operation of the stator 110 and the rotor 120 will be described below.

The rotor 120 is formed at its one end with two or more rotor blades 122 protruding toward the center of the rotor 120. The stator 11 has a predetermined angle The restricting member 112 is formed to prevent the rotor blade 122 from proceeding so as not to be rotated more than once. That is, the rotor blades 122 are formed in a + shape as shown in the figure, and the restricting members 112 are configured to receive projections on both side portions of the rotor blades 122. For example, the rotor blade 122 and the limiting member 112 are coupled to each other in a kind of teeth-coupled manner.

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

Meanwhile, a driving unit 130 for rotating the rotor 120 may be further provided between the limiting members 112. The driving unit 130 rotates the rotor 120 by a rotating motor, a battery, a pneumatic, a hydraulic, or an electromagnet. The driving means 130 is provided between the restricting members 112 of the plurality of restricting members 112. In addition, the driving means 130 may be replaced by various means. In the present invention, the driving means 130 is driven by the air pressure. The operation will be described in detail later.

Meanwhile, a tube 140 may be interposed between the first and second through holes 111 and 121 so as to be hollow. The tube 140 configured as described above is configured to be fixed to an edge region of the first through hole 111. [ Therefore, the tube 140 is not moved even by the rotation of the rotor 120. When the stator 110 is rotated and the first and second through holes 111 and 121 are staggered to close the channel 140, the tube 140 is pneumatically applied to the tube 140, (120) so as to maintain airtightness.

The rotator 110, the stator 120, and the tube 140 are preferably made of a relatively durable material, and should be capable of operating at a depth of about 300 m or less when underwater, So that it is preferable to be made of a material capable of withstanding such water pressure.

Hereinafter, an armed launching method using the middle water opening / closing valve of the present invention constructed as above will be described.

FIG. 4 is a perspective view showing a state in which the on-off valve is closed when the on-off valve is closed, FIG. 5 is a cross- Fig. 6 is a cross-sectional view showing a state in which air pressure is applied to the tube and airtightness between the stator and the rotor is interrupted, and the first and second through holes are staggered. Figs. FIG. 9 is a perspective view showing the state where the on-off valve is opened by the intermediate water in the underwater armed launch tube. FIG. 7 is a perspective view showing a state when the on- Fig. 9 is a cross-sectional view schematically showing a state in which the driving means is operated and the rotor is rotated. Fig. 9 shows a state in which the pneumatic pressure is released from the tube and the first and second through holes of the stator and the rotor are communicated The tanaen sectional view, Figure 10 is a flow chart showing the procedure of the armed firing method using an on-off valve in the water box of the present invention can be armed intermediate tubes.

Referring to FIGS. 4 to 10, the method for launching a weapon using an intermediate water path opening / closing valve according to the present invention is characterized in that, prior to launching the weapon, the rotor 110 and the stator 120 The through holes 111 and 121 are staggered to be adjacent to each other, and the airtightness is maintained by applying air pressure to the tube 140.

In this state, when any one of the plurality of launch tubes installed in the underwater condition is selected and is driven to launch the armed weapon, the pressure of the tube 140 is released, and the air in the tube 140 is released do. 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. 8, and the through holes 111 and 121 are positioned at the same positions And is communicated.

Then, when the first and second through holes 111 and 121 are in the same position, seawater flows as shown in FIG. 2, and the arm 230 is fired by the forced injection apparatus.

When the firing of the armed weapon 230 is completed, the front end of the launch tube 210 is closed, and the seawater introduced into the tube is discharged to the sea again. 5, the driving unit 130 rotates the rotor 120 in the opposite direction so that the first through holes 111 and the second through holes 112 are positioned at mutually staggered positions, As shown in FIG. 6, the airtightness is maintained by applying air pressure to the tube 140 to block the gap between the stator 110 and the rotor 120.

As described above, since the pressure of the tube 140 is released when the water channel is opened and closed by the rotation of the rotor 120, the stator 110 and the rotor 120 are completely separated from each other, . Since the tube 140 is interposed between the stator 110 and the rotor 120, the stator 110 and the rotor 120 are not eccentric because they are advantageous in wear resistance and mechanically always move in the same or opposite directions. Further, since the air pressure is applied to the tube 140 after the water channel is closed, the airtightness of the sealing member is much higher than that of the sealing member used in the past.
