[0026] See also Figure 1-3 , the present invention provides a double ball valve technical solution with self-locking protection function:

[0027] A double ball valve with a self-locking protection function comprises a pipeline 1, a control unit 2 arranged on the pipeline 1 and a ball valve 3 arranged in the pipeline 1, characterized in that the ball valve 3 is connected to the control unit 2, the control unit 2 comprises a self-locking protection component 21, a slave control component 22 and a main control component 23, the self-locking protection component 21 is connected to the main control component 23, and the main control component 23 is connected to the slave control component 22.

[0028] Specifically, the self-locking protection component 21 includes a water flow member 211 arranged between the ball valves 3 and a spoiler 212 arranged in the water flow member 211, the spoiler 212 is connected to the main control component 23, the ball valve 3 includes a first ball valve 31 and a second ball valve 32, the slave control component 22 includes a first rotating member 221 arranged on the first ball valve 31 and a second rotating member 222 on the second ball valve 32, and the first rotating member 221 and the second rotating member 222 are both provided with a driven gear 223, the main control component 23 includes a first connecting rod 231 connected to the spoiler 212, one end of the first connecting rod 231 passes through the water flow member 211 and is connected to the spoiler 212, the other end of the first connecting rod 231 is provided with a sleeve 232, an elastic member 233 is provided in the sleeve 232, the first connecting rod 231 is arranged in the sleeve 232 and passes through the elastic member 233, and a spring is arranged in the sleeve 232.

[0029] Furthermore, a control rod 234 is also provided in the sleeve 232, a pressure ring 235 is provided on the outer wall of the control rod 234, an annular groove 236 is provided at the bottom of the control rod 234, and multiple groups of card grooves 237 are provided along the annular groove 236. One end of the first connecting rod 231 provided in the sleeve 232 is provided with a hollow setting, and one end of the first connecting rod 231 provided in the sleeve 232 is provided with a through groove 238 in a mirror image, and a sliding member 239 is provided in the through groove 238. One end of the sliding member 239 is provided with a block 240 that cooperates with the card groove 237, and the other end is provided with a sliding rope 241. The first connecting rod 231 is provided with a fixed setting on the inner wall of one end of the sleeve 232. There is a pulley 242, and the slide rope 241 passes around the pulley 242 and is provided with a plate 243 at the other end thereof. A rod 244 is also provided at the bottom of the control rod 234, and the rod 244 cooperates with the plate 243; the annular groove 236 allows the block 240 to move along the groove in the annular groove 236, acting as a guide rail, and when the spring is compressed to the limit and rotated to a suitable angle, the block 240 will move upward as the slide rope 241 moves downward when the rod 244 presses the plate 243 downward, thereby falling into the groove 237. At this time, the rotation of the control rod 234 drives the first connecting rod 231, so that the rotation of the spoiler 212 can be realized.

[0030] Furthermore, the control rod 234 is connected to the sleeve 232 through threaded cooperation between the pressure ring 235. The advantage of using a threaded connection is that the thread can play an upper and lower limit role. A driving gear 245 is arranged on the outer wall of the sleeve 232. The driving gear 245 is connected to the driven gear 223. The driving gear 245 and the sleeve 232 are connected through a thread. A rotating wheel 246 is arranged on the top of the control rod 234. The rotating wheel 246 is connected to the driving gear 245. The rotating wheel 246 is used to rotate the control rod 234 and the driving gear 245, so that the two can rotate at the same time.

[0031] Working principle: When the rotating wheel 246 is rotated, the control rod 234 and the sleeve 232 are matched through threads, and the driving gear 245 and the sleeve 232 are also matched through threads, so the two can rotate synchronously with the rotation of the rotating wheel 246. At this time, the driving gear 245 drives the driven gear 223 to rotate, thereby realizing the rotation of the ball valve 3.

[0032] When the control rod 234 rotates and descends along the thread, the push rod 244 at its bottom will press the push plate 243, thereby pulling the slide rope 241 downward and driving the sliding member 239 to move upward in the through groove 238, thereby driving the block 240 to move upward and reach the annular groove 236. When the control rod 234 compresses the spring to the limit, the block 240 falls into the groove 237. At this time, the control rod 234 only rotates in the sleeve 232 without descending, so that the ball valve 3 and the spoiler 212 can rotate synchronously.

[0033] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
