[0002] Ultra-high pressure pipeline sealing valves are key equipment to ensure industrial safety. Their sealing performance and reliability directly affect the safety and stability of pipeline operation. By adopting advanced high-pressure resistant materials and intelligent monitoring systems, the sealing performance and safety of the valves are improved. This valve can not only effectively prevent leakage and accidents, but also ensure the stable operation of the pipeline system, providing reliable protection for industrial production.

[0004] However, in the implementation of relevant technologies, it was found that a sealing valve of the above design has the following problems: when the above-mentioned device is used to seal the pipeline, if the design of the sealing plug is easily damaged after long-term use, once the sealing plug is damaged, the valve cannot be resealed. The damaged sealing plug will cause the valve to be unable to maintain the necessary sealing performance, and leakage may occur, thereby affecting the normal operation and efficiency of the system. In systems that carry high pressure or critical tasks, this failure mode may cause serious safety hazards and even lead to accidents. In view of this, an ultra-high pressure pipeline sealing valve is provided to overcome the above-mentioned defects. Utility Model Content

[0025] Embodiment 1

[0026] like Figure 1 - Figure 4 The utility model provides a technical solution: an ultra-high pressure pipeline sealing valve, comprising a water inlet pipeline 1 and a valve body 5 installed on one side of the water inlet pipeline 1, a fixing component 6 is arranged on the top of the valve body 5, a connecting component 7 is arranged on the top of the fixing component 6, and a first sealing component 9 is arranged on the connecting component 7;

[0027] The first sealing assembly 9 includes a valve stem 91 , a hand wheel 10 is arranged on the top of the valve stem 91 , a cover plate 92 is arranged at one end of the valve stem 91 away from the hand wheel 10 , and a cover plate leather cover 93 is arranged on the outer side of the cover plate 92 .

[0028] A second sealing assembly 12 is provided on one side of the water inlet pipe 1, and the second sealing assembly 12 includes a connecting rod 122. A cover plate 121 is provided on the other end of the connecting rod 122. Connecting blocks 123 are provided on both sides of the cover plate 121. A sliding plate 124 is provided on one end of the water inlet pipe 1, and a sliding plate groove 125 is provided on the sliding plate 124.

[0029] In specific implementation, by rotating the handwheel 10, the valve stem 91 connected thereto can be driven to rotate, and this rotational action will be transmitted to the cover plate 92, causing it to rise or fall, thereby controlling the circulation of the fluid. When the valve needs to be closed, the cover plate 92 will push the cover plate leather sleeve 93 to tightly cover the valve body opening 11 to ensure sealing and prevent any possible leakage. Through the lifting and lowering movement of the valve stem 91, precise regulation and control of the fluid flow can be achieved. The connecting rod 122 is connected to the valve stem 91. As the valve stem 91 moves up and down, it will also rise and fall accordingly, and move along the sliding plate groove 125 on the sliding plate 124 through the cover plate 121. When the water inlet pipe 1 needs to be closed, the cover plate 121 will slide to the appropriate position to block the water flow.

[0030] Embodiment 2

[0031] like Figure 1 - Figure 4The utility model provides a technical solution: the fixing assembly 6 includes a lower fixing plate 61, an upper fixing plate 62 is arranged on the top of the lower fixing plate 61, a screw 63 is arranged on the upper fixing plate 62, the other end of the screw 63 is rotatably connected with a nut 64, and the lower fixing plate 61 and the upper fixing plate 62 are fixed by the screw 63 and the nut 64.

[0032] The connecting assembly 7 includes a fixing block 71 , a slot is formed in the fixing block 71 , connecting handles 72 are provided on both sides of the fixing block 71 , a connecting screw rod 73 is provided on the connecting handle 72 , and a pressure cover 8 is provided on the top of the connecting screw rod 73 .

[0033] A valve body opening 11 is provided in the valve body 5 , and a flange 1 3 and a flange 2 4 are provided on the side of the water inlet pipe 1 and the water outlet pipe 2 away from the valve body 5 .

[0034] During specific implementation, the lower fixing plate 61 and the upper fixing plate 62 work together to firmly fix the connecting component 7 in the appropriate position. The stability between the two fixing plates is guaranteed by the close combination of the upper fixing plate 62 and the screw 1 63. This structure not only provides a solid support for the connecting component 7, but also lays a foundation for the reliability of the entire valve system. With the help of the fixing block 71 and the pressure cover 8, the first sealing component 9 can be accurately fixed in a predetermined position to ensure that it correctly performs the task of closing the valve body opening 11. The design of the connecting screw 73 and the connecting handle 72 gives the user the ability to adjust the height of the connecting component 7, thereby making the height of the first sealing component 9 adjustable to adapt to different working environments and requirements. The flange 1 3 and the flange 2 4 enable the device to be easily connected and fixed to other pipelines, ensuring the integrity of the entire system and the seamless transmission of the fluid. Through these designed components, the valve system achieves the performance of easy installation, adjustment and sealing.

[0035] Working principle:

[0036] like Figure 1-4As shown, the device can be easily connected and fixed to other pipelines through flange 1 3 and flange 2 4, ensuring the integrity of the entire system and seamless transmission of the fluid. Through these designed components, the valve system achieves the performance of easy installation, adjustment and sealing. The lower fixing plate 61 and the upper fixing plate 62 work together to fix the connecting component 7 firmly in the appropriate position. The stability between the two fixing plates is guaranteed by the tight combination of the upper fixing plate 62 and the screw 1 63. This structure not only provides a solid support for the connecting component 7, but also lays a foundation for the reliability of the entire valve system. With the help of the fixing block 71 and the pressure cover 8, the first sealing component 9 can be accurately fixed in a predetermined position to ensure that it correctly performs the task of closing the valve body opening 11. The design of the connecting screw 73 and the connecting handle 72 gives the user the ability to adjust the height of the connecting component 7. The height of the first sealing component 9 becomes adjustable to adapt to different working environments and requirements. By rotating the hand wheel 10, the valve stem 91 connected thereto can be driven to rotate, and this rotation will be transmitted to the cover plate 1 92, causing it to rise or fall, thereby controlling the circulation of the fluid. When the valve needs to be closed, the cover plate 1 92 will push the cover plate leather sleeve 93 to tightly cover the valve body opening 11 to ensure sealing and prevent any possible leakage. Through the lifting and lowering movement of the valve stem 91, precise regulation and control of the fluid flow can be achieved. The connecting rod 122 is connected to the valve stem 91. As the valve stem 91 moves up and down, it will also rise and fall accordingly, and move along the sliding plate slot 125 on the sliding plate 124 through the cover plate 2 121. When the water inlet pipe 1 needs to be closed, the cover plate 2 121 will slide to the appropriate position to block the water flow.
