[0023] Example 1

[0024] like Figures 1-4 As shown in the figure, the valve quick-release interface proposed in this embodiment includes a valve pipe 1 and a connecting pipe 2.

[0025] The end of the connecting pipe 2 is provided with a first thread 71, and the inner wall of the valve pipe 1 is provided with a second thread 72 that is compatible with the first thread 71.

[0026] A first limiting ring 9 is connected to the connecting pipe 2, and a second sealing ring 10 is installed on the first limiting ring 9.

[0027] Multiple second annular grooves 201 are provided on the connecting pipe 2; multiple first annular grooves 101 are provided on the inner wall of the valve pipe 1, and the multiple first annular grooves 101 are arranged one-to-one with the multiple second annular grooves 201. Two second arc-shaped plates 12 are symmetrically arranged on the inner side of each of the multiple first annular grooves 101. A sealing ring 13 is connected to each of the two second arc-shaped plates 12. The sealing ring 13 is clearance-fitted with both the first annular groove 101 and the second annular groove 201. Both the second arc-shaped plates 12 and the sealing rings 13 are semi-circular ring structures. Two first arc-shaped plates 3 are symmetrically arranged on the outer wall of the valve pipe 1. A movable rod 14 is connected between the upper first arc-shaped plate 3 and the multiple second arc-shaped plates 12 at the upper end. The lower first arc-shaped plate 3 is connected to the valve pipe 1. Multiple movable rods 14 are also connected between plate 3 and multiple second arc-shaped plates 12 at the lower end. The movable rods movably penetrate the wall of valve pipe 1. Each movable rod 14 is equipped with an elastic reset assembly, which includes a spring 15 and a limiting block 16. The limiting block 16 is connected to the movable rod 14. A mounting groove 102 for the limiting block 16 to move is provided on valve pipe 1. The mounting groove 102 is connected to the first annular groove 101. The spring 15 is sleeved on the movable rod 14. A third sealing ring 17 is connected to the limiting block 16. This arrangement can prevent liquid from seeping out from the gap between the movable rod 14 and valve pipe 1. A drive assembly for driving the two first arc-shaped plates 3 to move away from each other is installed on valve pipe 1.

[0028] The first sealing ring 8 is installed at the end opening of the communication pipe 2, and the second limiting ring 11 is installed on the inner side of the valve pipe 1. When the communication pipe 2 is rotated to the terminal position, the first sealing ring 8 abuts against the second limiting ring 11, thereby further enhancing the sealing performance of the connection between the communication pipe 2 and the valve pipe 1.

[0029] Specifically, the communication pipe 2 is inserted into the valve pipe 1, and then the communication pipe 2 is rotated to be screwed with the valve pipe 1. When the communication pipe 2 is rotated to the limiting position, the second sealing ring 10 abuts against the outer end of the valve pipe 1, thereby playing a sealing role. Before the communication pipe 2 is rotated, it is necessary to ensure that the plurality of sealing rings 13 are arranged in the corresponding first annular grooves 101, so as to prevent the sealing rings 13 from hindering the movement of the communication pipe 2. When the communication pipe 2 is rotated to the set position, the plurality of second annular grooves 201 correspond to the plurality of first annular grooves 101 one by one, and then the plurality of sealing rings 13 are reset, so that the plurality of sealing rings 13 are clamped into the corresponding second annular grooves 201, thereby increasing the sealing area between the valve pipe 1 and the communication pipe 2, and also playing a role of preventing the valve pipe 1 and the communication pipe 2 from loosening, thereby playing a limiting role. In summary, the technical scheme has the advantages of high disassembly and assembly efficiency, good sealing effect, and stable installation.

[0030] It should be noted that the valve pipe 1 is connected with the inside of the valve body and is used for connecting external pipelines. The wall thickness of the end of the valve pipe 1 adjacent to the communication pipe 2 is greater than the main body thickness, so as to provide sufficient installation space for the elastic reset assembly.

[0031] Embodiment two

[0032] As shown in Figure 1 and Figure 4 , the valve quick disassembly interface provided in the embodiment includes a rotating ring 4, a sliding ring 5, and two tapered blocks 6. The rotating ring 4 is screwed with the outer wall of the valve pipe 1. The sliding ring 5 is slidingly installed on the outer wall of the valve pipe 1. The two tapered blocks 6 are symmetrically arranged on the sliding ring 5. There is a gap between the two first arc-shaped plates 3.

[0033] The rotating ring 4 is rotated to drive the sliding ring 5 to move to one side of the valve pipe 1. The sliding ring 5 drives the two tapered blocks 6 to be clamped into the two gaps between the two first arc-shaped plates 3. Since the tapered blocks 6 are tapered, the two first arc-shaped plates 3 are gradually separated during the movement of the tapered blocks 6, thereby driving the plurality of sealing rings 13 to move to the inner side of the first annular grooves 101. When the installation of the communication pipe 2 is completed, the rotating ring 4 is reversely rotated to reset. At this time, the sealing rings 13 are driven to reset under the elastic force of the spring 15. In summary, the driving assembly driving structure provided in the embodiment is simple and efficient.

[0034] The embodiment of the utility model is described in detail above in combination with the drawings, but the utility model is not limited to this, and various changes can be made within the knowledge range possessed by the person skilled in the art without departing from the purpose of the utility model.
