[0044] The implementation principle of this utility model is as follows: Before using the equipment, the bottle valve 9 is placed under the placement hole 517. The gripper 505 immediately grabs the bottle valve 9 and places it in the corresponding position. The second electric telescopic rod 519 moves to fix the position of the bottle valve 9. The gripper 505 is released. After the bottle valve 9 is placed, the sliding plate 516 moves to connect the lower interface of the bottle valve 9 to the outlet of the general pipeline 514. The water pump 508 operates and draws water from the water tank 3 through the water pipe 507 to perform a water pressure and airtightness test on the bottle valve 9. After the test is completed, the gripper 505 rotates the knob of the bottle valve 9. When bottle valve 9 is opened, pressure pump 511 operates, expelling residual water from general pipe 514 and bottle valve 9 through gas, while ensuring the dryness of the inside of general pipe 514 and bottle valve 9, thus extending their service life. Then, gripper 505 grabs bottle valve 9, and second electric telescopic rod 519 retracts, moving bottle valve 9 above storage basket 402 via first sliding rail 501. First electric telescopic rod 503 extends or retracts appropriately according to the number of products in the basket, placing bottle valve 9 into storage basket 402 for easy collection by operators.
