[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] like Figure 1-5As shown, a sterile sampling valve cleaning device comprises a sampling valve body 1, wherein two channels 4 are symmetrically provided in the sampling valve body 1 near the valve port, a spiral tube 5 is installed in the channel 4, a thread is provided on the outer wall of the spiral tube 5 and is spirally installed on the inner wall of the channel 4, and a sealing gasket is provided on the outer wall of the spiral tube 5 to achieve sealing and waterproofing, a spring rod 7 is fixedly connected to the inner wall of the spiral tube 5, a screw 13 is fixedly connected to the telescopic end of the spring rod 7, and a mounting seat 16 is fixedly connected to the axial surface of the telescopic rod of the spring rod 7, and a plurality of regulating plugs 8 distributed in an annular array are fixedly connected to the mounting seat 16, a hollow plate 9 sleeved on the screw 13 is fixedly connected to the inner wall of the spiral tube 5, and the hollow parts of the hollow plate 9 correspond to the plurality of regulating plugs 8 one by one, and the elastic support of the spring rod 7 is utilized to make the regulating plug 8 on the mounting seat 16 tightly plug the hollow part of the hollow plate 9 to achieve sealing of the hollow plate 9, and the sealing between the screw 13 and the hollow plate 9 is achieved by means of a packing seal, so that When the rod 13 moves relative to the hollow plate 9, the spring rod 7 is forced to elastically contract, so that the mounting seat 16 at the telescopic end of the spring rod 7 drives the adjusting plug 8 to disengage from the hollow part of the hollow plate 9, so that the hollow plate 9 can be opened, thereby facilitating the passage of the medium. In addition, as shown in the figure, the adjusting plug 8 selected in this scheme is conical, and the surface is covered with a layer of silicone pad to ensure the sealing of the inner wall of the hollow part of the hollow plate 9. The spiral tube 5 is threadedly connected with a connecting tube 2, and two connecting tubes 2 are provided. An adjusting member for adjusting the opening degree of the hollow part of the hollow plate 9 is provided in the connecting tube 2. Therefore, after the adjusting member is installed on the connecting tube 2 on the spiral tube 5, when the valve disc inside the sampling valve body 1 is in the closed position, high-temperature steam or clean water can flow from one connecting tube 2 through the other connecting tube 2, thereby completing the cleaning or sterilization of the inner cavity of the sampling valve body 1 and the inner wall of the pipeline. When the valve disc of the sampling valve body 1 is in the open position, the fluid sampling operation can be completed.

[0025] In order to drive the adjustment plug 8 to move and control the flow rate of the spiral tube 5: a threaded ring 15 threadedly connected to the screw rod 13 is rotatably connected on the upper surface of the hollow plate 9, and a plurality of slots 20 are provided on the outer wall of the threaded ring 15. The adjusting member includes a holder 18 fixed to a pipe opening on one side of the connecting pipe 2, and a block 17 plugged into the outer wall of the threaded ring 15 is rotatably connected in the holder 18. The inner wall of the block 17 is clearance-matched with the outer wall of the threaded ring 15, and a protrusion 19 plugged into the plurality of slots 20 is fixedly connected to the inner wall of the block 17. In the process of spirally installing the connecting pipe 2, the block 17 can be smoothly installed on the threaded ring 15 through the plugging of the protrusion 19 and the slot 20 by rotating and adjusting the block 17. Then, after the connecting pipe 2 is installed, the threaded ring 15 can be rotated by rotating the block 17. By utilizing the threaded connection between the threaded ring 15 and the screw rod 13 and the fact that the screw rod 13 cannot rotate, the screw rod 13 can slide relative to the hollow plate 9.

[0026] In order to drive the block 17 to rotate: the adjusting member also includes a rotating seat 3 fixedly connected to the other pipe opening of the inner wall of the connecting tube 2, a worm wheel 10 is rotatably connected to the rotating seat 3, the center line of the worm wheel 10 coincides with the center line of the block 17, and a connecting frame 11 is fixedly connected between the end face of the worm wheel 10 and the block 17, a worm 12 meshing with the worm wheel 10 is rotatably connected to the inner wall of the connecting tube 2, and one end of the worm 12 extends outward through the connecting tube 2, the meshing worm wheel 10 is rotated by rotating the worm 12, and then the connecting frame 11 drives the block 17 to rotate.

[0027] In order to ensure that the mounting seat 16 does not shake, a plurality of guide rods 14 distributed in a circular array are fixedly connected to the mounting seat 16, and a protrusion for the guide rods 14 to penetrate is extended inwardly from the inner wall of the spiral tube 5.

[0028] In addition, the spiral tube 5 is threadedly connected to a sealing cover 6. Because of the elastic push of the spring rod 7 inside the spiral tube 5, the adjusting plug 8 can be forced to seal the hollow part of the hollow plate 9 to achieve sealing. When the connecting tube 2 is not in use, the sealing cover 6 can be installed to further ensure the sealing of the spiral tube 5.

[0029] Working principle: when cleaning the inside of the sampling valve body 1, rotate and remove the sealing cover 6, and install the two connecting pipes 2 on the two spiral tube 5 pipe openings respectively. During the installation process, the worm gear 10 drives the connecting frame 11 to rotate by rotating the worm 12, so that the clamping block 17 rotates a certain angle to ensure that the clamping block 17 can be smoothly plugged into the threaded ring 15. After the connecting pipe 2 is installed, the clamping block 17 is driven to rotate by the worm 12 again to rotate the threaded ring 15, thereby realizing the movement of the screw 13 and forcing the spring rod 7 to elastically contract, so that the adjusting plug 8 on the surface of the mounting seat 16 on the telescopic rod of the spring rod 7 is separated from the hollow part of the hollow plate 9, so that the inside of the spiral tube 5 is transparent. When the valve disc inside the sampling valve body 1 is in the closed position, high-temperature steam or clean water can flow from one connecting pipe 2 through the other connecting pipe 2, thereby completing the cleaning or sterilization of the inner cavity of the sampling valve body 1 and the inner wall of the pipeline. When the valve disc of the sampling valve body 1 is in the open position, the fluid sampling operation can be completed.
