DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 , an adjustable installation structure of AB valve, including a cleaning chamber 1, A valve 2, B valve 3 and a barrel 4, the B valve is installed at the upper end of the barrel 4, the A valve is arranged in the cleaning chamber 1 and near the top position, the B valve 3 is located directly below the A valve 2, and a storage plate 6 is provided in the cleaning chamber 1 and near the bottom position for supporting the barrel 4, the upper end of the storage plate 6 is provided with an opening corresponding to the barrel 4, the lower end of the barrel 4 passes through the opening, the inner diameter of the opening is 1.2-1.5 times the diameter of the barrel 4, and is used to accommodate larger barrels 4 of different sizes;

[0023] The cam 17 is fixedly mounted on the sidewall of the cam 14 so that the cam 14 can be moved and the cam 14 can be moved to the storage tank 4.

[0024] In this embodiment, the lower end of the storage plate 6 is fixedly connected to four rectangularly distributed support rods 5 for supporting the storage plate 6. The lower end of the support rod 5 is rotatably connected to a universal wheel for facilitating the movement of the storage plate 6. A plurality of positioning rods 11 are fixedly connected to the rear side wall of the storage plate 6 for cooperating with the positioning cylinder 12 to position the storage plate 6. The positioning cylinder 12 is slidably sleeved on the positioning rod 11 for inserting the positioning rod 11. The end of the positioning cylinder 12 away from the storage plate 6 is fixedly connected to the inner wall of the cleaning chamber 1;

[0025] In this embodiment, a support plate 8 is fixedly connected to the inner wall of the cleaning chamber 1 for supporting a spring 9. A square-shaped card rod 7 is slidably inserted into the lower end of the support plate 8 for cooperating with the card slot to lock the position of the storage plate 6. The upper end of the storage plate 6 is provided with a card slot corresponding to the card rod 7. The lower end of the card rod 7 slides and extends into the card slot. The upper end of the card rod 7 passes through the support plate 8 and is fixedly connected with a pull ring 10 for facilitating the user to push and pull the card rod 7. A rubber sleeve is fixedly sleeved on the pull ring 10 for improving the comfort of the pull ring 10 when in use. A spring 9 is sleeved on the card rod 7 for providing downward pulling force to the pull ring 10, thereby preventing the card rod 7 from loosening upward from the card slot. The two ends of the spring 9 are fixedly connected to the lower end of the pull ring 10 and the upper end of the support plate 8 respectively.

[0026] In this embodiment, the material barrel 4 equipped with the B valve 3 is first placed into the opening, and then the position of the clamping block 14 is adjusted according to the size of the material barrel 4. At the same time, the two electric push rods 13 are started to drive the clamping block 14 to move, and the material barrel 4 is clamped and fixed in the opening by the clamping block 14. Then, the storage plate 6 is moved to and pushed into the cleaning chamber 1 through the universal wheel and the support rod 5. At the same time, the positioning rod 11 is directed towards the positioning cylinder 12. When all the positioning rods 11 are inserted into the positioning cylinder 12, the storage plate 6 can be positioned. At this time, the B valve 3 is directly below the A valve 2, which is convenient for the installation and docking of the A valve 2 and the B valve 3. At the same time, the pull ring 10 is pushed to drive the clamping rod 7 to be inserted into the clamping slot, which can lock the position of the storage plate 6 to avoid the position movement and offset of the storage plate 6 after positioning. The setting of the spring 9 can prevent the clamping rod 7 from loosening, thereby improving reliability.
