[0002] At present, the side channels of underwater ships and submersibles' sea-access systems mostly use manual control valves. In order to ensure the safety of the side channels, a second locking valve must be installed after the first side valve of the sea-access pipeline as required. The two-locking design further enhances the safety of the sea-access pipeline and prevents the risk of pipeline damage in unexpected situations. When a damage control emergency occurs, the valve of the side channel is manually closed. However, manual operation to handle damage control emergencies has a slow response speed; and the two locks occupy a large amount of overall resources, especially on small and medium-sized submersibles.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the device includes a valve body 1 and a bracket 2, the bracket 2 is fixed to the top of the valve body 1, a driving assembly 3 is arranged on the left side of the bracket 2, the driving assembly 3 includes a motor 301 fixed to the left side of the bracket 2, a rotating shaft 302 is fixed at the bottom of the motor 301, and a guide groove 303 is integrally arranged inside the rotating shaft 302, a first sphere 304 is arranged on the left side of the valve body 1, a first drainage hole 305 integrally arranged inside the first sphere 304 is a through hole design, and a rotating pin 306 fixed at the top of the first sphere 304 rotates and penetrates the valve body 1 On the top left side, the latch 307 that slides inside the swing pin 306 is arranged inside the guide groove 303, and a spring 308 is fixed between the bottom of the latch 307 and the swing pin 306, and guide holes 309 are integrally provided on the left and right sides of the swing pin 306, and the connecting block 310 that slides inside the guide hole 309 is fixedly connected to the outer wall of the swing pin 306, and the external fixed sleeve of the connecting block 310 is provided with an installation sleeve 311, and the internal upper end of the installation sleeve 311 is integrally provided with a number of sockets 312, and a rod 313 is threaded through the lower end of the left side of the outside of the bracket 2.

[0029] The motor 301 is a reduction stepping motor with a self-locking function, and the motor 301 stops running every time it rotates 90 degrees. The cross-sections of the guide groove 303 and the latch 307 are square in design. The staff turns on the motor 301, and the motor 301 drives the rotating shaft 302 to drive the latch 307 to link the rotating pin 306 and the first sphere 304 to rotate. When the first sphere 304 and the first drainage hole 305 rotate 90 degrees, the motor 301 stops running. When the motor 301 is damaged and cannot be used normally, the staff pulls the installation sleeve 311 downward by hand, so that the installation sleeve 311 drives the connecting block 310 and the latch 307 to disengage from the guide groove 303, and the spring 308 is deformed. At this time, the insertion rod 313 and the socket 312 overlap with each other. The staff then rotates the installation sleeve 311 by hand, so that the installation sleeve 311 drives the connecting block 310 to link the latch 307 and the rotating pin 306 together with the first sphere 304 to rotate. Through the above method, manual control of the first sphere 304 is realized. After the rotation is completed, the staff uses the other hand to screw the insertion rod 313 into the current corresponding socket 312 to lock the angle of the first sphere 304 after rotation.

[0032] According to the operation method in Example 1, when the first sphere 304 and the first drainage hole 305 are rotated to coincide with the clearance hole 6, the staff manually rotates the rotating rod 9 so that the rotating rod 9 drives the second sphere 4 to rotate until the limiting rod 13 coincides with the second limiting hole 12, and the second drainage hole 5 coincides with the clearance hole 6. The staff then rotates the limiting rod 13 into the second limiting hole 12. At this time, the liquid is discharged from the liquid inlet pipe 7 through the first drainage hole 305, the clearance hole 6, and then the second drainage hole 5 through the drainage pipe 8. When the limiting rod 13 coincides with the first limiting hole 11, it means that the second drainage hole 5 and the clearance hole 6 are in a mutually misaligned state.
