[0041] It can be understood that the first stopper 121 and the second stopper 131 play a role of transmission, the first password ring 120 is in transmission through the first stopper 121 and the second stopper 131 on the surface of the upper second password ring 130, the upper second password ring 130 is in transmission through the second stopper 131 on the bottom surface and the second stopper 131 on the bottom surface of the lower second password ring 130, so in actual use, first of all, the password disc 110 needs to be rotated to directly drive the first password ring 120 to rotate, until the first stopper 121 of the first password ring 120 can cooperate with the second stopper 131 on the surface of the upper second password ring 130, and the second stopper 131 on the bottom surface of the upper second password ring 130 can cooperate with the second stopper 131 on the bottom surface of the lower second password ring 130, so that the password disc 110 drives the first password ring 120 and the second password ring 130 to rotate at the same time, then rotates to the correct password position to input the password of the lower second password ring 130, and then reversely rotates, until the first stopper 121 of the first password ring 120 can cooperate with the second stopper 131 on the surface of the upper second password ring 130 again, then rotates to the correct password position to input the password of the upper second password ring 130, and finally reversely rotates again, so that the password disc 110 only drives the first password ring 120 to rotate, and rotates to the correct password position to input the password of the first password ring 120, finally, when all the three passwords are correct, the locking assembly 140 can drive the valve core component 300 to switch the state.

[0042] Preferably, a gap washer 150 is arranged between adjacent second password rings 130 and between the first password ring 120 and the second password ring 130. It can be understood that the main role of the gap washer 150 is to isolate the rotation of the upper and lower password rings, so as to avoid the position deviation of the upper and lower password rings when the password ring rotates alone. Specifically, the washer can be set as an inner circlip washer, and the size thereof can be set as needed, for example, the outer diameter is set to be smaller so as not to interfere with the slider 142 of the locking assembly 140, and if the outer diameter is too large, a corresponding mark port 160 is needed to be set for the slider 142 to pass through.

[0043] Preferably, the first password ring 120 and the second password ring 130 are respectively provided with mark ports 160, and the slider 142 can slide through the mark ports 160 when the first password ring 120 and the second password ring 130 respectively rotate to a specific position. It can be understood that when the first password ring 120 and each second password ring 130 are respectively in the correct position of the password, the mark port 160 is also in the correct position, at this time, the slider 142 can pass through each mark port 160 to slide smoothly, so as to drive the valve core component 300, as long as the position of at least one password ring is incorrect, the slider 142 cannot slide smoothly, thereby ensuring the authorized management effect of the valve.

[0044] In some embodiments of the present application, the locking assembly 140 comprises a locking base 141, a sliding block 142 slidingly arranged on the locking base 141, and a first elastic member 143 acting on the sliding block 142 to make the sliding block 142 have a tendency to switch the valve core component 300 to the unlocked state.

It can be understood that the locking base 141 needs to be fixed in the circumferential direction during the entire working process of the rotary disc combination lock component 100, and therefore the positioning member 171 is arranged to limit the locking base 141, and the positioning member 171 is adapted to be matched with the limiting opening 1411 to avoid rotation of the locking base 141. Further, the limiting rod 1412 is used to limit the rotation stroke of the lower second password ring 130, so that the user can feel the hand feeling after the password disc 110 is rotated for multiple turns, which represents that the zero adjustment has been completed at this time, and then the lower second password ring 130 can be reversed and driven to the correct position to perform the password input action.

[0048] Further, the password valve anti-disassembly function in the related art is simple, and generally uses glass beads and a spring plus a clamping strip inside. When disassembling, a special chemical solution is used to dissolve the glass beads, and then the valve is disassembled. The main disadvantage is that the special chemical solution for dissolving has high failure probability and is not environmentally friendly, and the chemical solution formula is a greater hidden danger if leaked.
