[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 4-Figure 6As shown, the utility model provides an embodiment: a high-pressure valve sealing component, including a valve body 1 as a connection, one end of the valve body 1 is detachably connected to a top cover 4, the inner wall of the top cover 4 is fixedly connected to a limit ring 5, the inner wall of the limit ring 5 is provided with a handle 10 for limiting the handle 10 and the valve disc 13, one end of the handle 10 is provided with a valve disc 13 for lifting the valve disc 13, the bottom end of the handle 10 is rotatably connected to the top of the top cover 4, and is rotatably connected to a connecting tube 7 on the inner wall of the limit ring 5, the lower side of the inner wall of the connecting tube 7 is fixedly connected to a tension spring 8, and the tension spring 8 is also provided. One end is fixedly connected to a snap ring 9, the outer wall of the connecting tube 7 is slidably connected to the inner wall of the snap ring 9, the inner wall of the snap ring 9 is slidably connected to the outer wall of the handle 10, and a plurality of slots 6 are provided on the top of the limit ring 5. The shape of the snap ring 9 matches the slot 6. The left and right ends of the snap ring 9 are fixedly connected to connecting plates for pulling the snap ring 9 upward through the connecting plates to rotate the handle 10. The threaded rod 11 is fixedly connected to the bottom end of the handle 10, and the outer wall of the threaded rod 11 is threadedly connected to the valve stem 12. The outer wall of the valve stem 12 is slidably connected to the inner wall of the top cover 4, and the bottom end of the valve stem 12 is fixedly connected to the top of the valve disc 13.

[0029] Specifically, when using the valve body 1, the connecting plate is pulled upward to remove the retaining ring 9 from the slot 6, and the handle 10 can be rotated. The handle 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the valve stem 12 of the outer wall to slide downward, and the valve stem 12 drives the valve disc 13 and the sealing ring 14 to move downward. Secondly, when there is no need to adjust the position of the valve disc 13, the connecting plate is loosened, and the retaining ring 9 is pulled downward by the tension spring 8, and the retaining ring 9 is stuck in the slot 6. The handle 10 and the valve disc 13 are limited to avoid loosening during sealing. This can effectively prevent the valve disc 13 from loosening due to excessive movement or vibration during the sealing process, keep the valve disc 13 stable in a predetermined position, and help ensure the durability of the sealing performance.

[0030] Reference Figure 1-Figure 3 As shown, the valve flap 13 serves as a seal, and the outer wall of the valve flap 13 is fixedly connected to a sealing ring 14 for sealing in various ways. A water outlet 2 is provided on the inner wall of the valve body 1, and the outer wall of the valve flap 13 is arranged on the inner wall of the water outlet 2. The shape of the valve flap 13 matches the water outlet 2. An annular groove 3 is provided on the inner wall of the valve body 1 corresponding to the water outlet 2 toward the outside. The outer wall of the sealing ring 14 is arranged on the inner wall of the annular groove 3, and the shape of the sealing ring 14 matches the annular groove 3.

[0031] Specifically, when using the valve body 1, by pulling the connecting plate upwards, the clamping ring 9 is removed from the clamping groove 6, and the handle 10 can be rotated. The handle 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the valve stem 12 on the outer wall to slide downward. The valve stem 12 drives the valve disc 13 and the sealing ring 14 to move downward, and the valve disc 13 is stuck into the water outlet 2, and the sealing ring 14 is stuck into the annular groove 3, and the valve can be closed. The two sealing methods of the valve disc 13 and the sealing ring 14 can significantly improve the sealing effect of the valve, extend the service life, and ensure the safety of the system and the reliability of operation.

[0032] Working principle: After the high-pressure valve is in place, when the valve body 1 needs to be closed, the connecting plate is pulled upward, which drives the snap ring 9 to move upward. At this time, the snap ring 9 will be removed from the inner wall of the groove 6, explaining the limit of the handle 10, and the handle 10 can be rotated. The handle 10 will synchronously drive the snap ring 9 and the connecting tube 7 to rotate. At the same time, the handle 10 will drive the threaded rod 11 to rotate, and the threaded rod 11 will drive the valve stem 12 on the outer wall to slide downward. The valve stem 12 drives the valve disc 13 and the sealing ring 14 to move downward. At the same time, the valve disc 13 will be stuck into the water outlet 2, and the sealing ring 14 will be stuck in the annular groove 3, which can close the valve. Secondly, after closing or opening, first loosen the connecting plate, and the snap ring 9 will be pulled downward by the elastic force of the tension spring 8. At the same time, the inner wall of the snap ring 9 will slide downward on the outer wall of the connecting tube 7, thereby blocking the snap ring 9 into the groove 6, and the limiting of the handle 10, valve disc 13 and sealing ring 14 can be completed.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
