Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a marine valve with a leak-proof function. Background Technology

[0002] Valves, as key control components, are widely used in various pipeline systems to regulate or cut off fluid flow. However, in actual use, valves often face leakage problems due to insufficient sealing at connection points, especially in high-pressure or highly corrosive fluid environments. Leakage not only wastes resources but may also cause safety hazards. In addition, the valve's regulating structure is prone to loosening or decreased regulating accuracy after long-term use, which further exacerbates the decline in sealing performance and operational unreliability.

[0003] Therefore, it is essential to provide a marine valve with leak-proof function to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a marine valve with leak-proof functionality. Through innovative design, it solves the technical problems of leakage and unstable connection during valve use. This is mainly achieved by setting a sealed buffer cavity between the valve body and the connecting pipe, filled with pressure-resistant and corrosion-resistant elastic sealing material, effectively preventing media leakage. Simultaneously, an adjustment structure allows for flexible adjustment and stable support of the connection points. The double-layer connecting plate design and interlocking tooth structure in the adjustment structure enhance the support strength, while the anti-loosening structure further ensures connection reliability. The reinforcing ribs on the outer wall of the conveying pipe match the hooks of the connecting plate, further improving connection stability. Overall, this invention, through multiple leak-proof and stable designs, significantly improves the safety and service life of the valve, making it suitable for various complex working conditions.

[0018] The present invention will be further described in conjunction with the following embodiments.

[0019] Example 1. like Figure 1-3 As shown, a marine valve with a leak-proof function is provided by this utility model. The valve with a leak-proof structure includes a locking nut 19, a connecting pipe 2, an inlet pipe 3, a conveying pipe 4, a rotating shaft, and a rotating ring. The locking nut 19 is the main pressure-bearing component, used to control the flow of fluid. The connecting pipe 2 is installed on its arc surface for connecting to an external pipe. The rotating shaft is fixedly installed on the upper surface of the locking nut 19. One end of the rotating shaft is fixedly connected to a rotating ring. Rotating the rotating ring can drive the rotating shaft to rotate to control the opening and closing of the valve. One end of the connecting pipe 2 is fixedly connected to the inlet pipe 3. A conveying pipe 4 is installed on one side of the inlet pipe 3 for fluid input or output.

[0020] An adjustment structure 5 is provided on the arc surface of the connecting pipe 2. The adjustment structure 5 includes a fixed seat 6, a connecting plate 7, a sliding groove 8, and a screw 9. The upper surface of the fixed seat 6 is fixedly connected to the connecting pipe 2 by welding or bolts. The connecting plate 7 is rotatably connected to the inner wall of the fixed seat 6. The connecting plate 7 is hook-shaped, and its hook part is used to form a stable connection with the conveying pipe 4 or other components. A sliding groove 8 is provided on one side of the fixed seat 6. The screw 9 is slidably connected to the inner wall of the sliding groove 8. By rotating the screw 9, the connecting plate 7 can be driven to adjust the angle or position, thereby realizing the adjustment of the tightness of the connection.

[0021] The fixed base 6 is designed with an adjustable angle structure, specifically including a base 15 and a rotating base 16. The base 15 is fixedly connected to the connecting pipe 2, and the rotating base 16 is connected to the base 15 by an adjusting bolt. The adjusting bolt passes through the arc groove on the base 15, so that the rotating base 16 can be adjusted within a preset angle range. By loosening the adjusting bolt, the angle of the rotating base 16 can be adjusted to adapt to different installation requirements. After adjustment, tightening the adjusting bolt will fix it.

[0022] A sealing buffer cavity 10 is provided between the locking nut 19 and the connecting pipe 2. The sealing buffer cavity 10 has a ring structure and is distributed circumferentially along the connection between the locking nut 19 and the connecting pipe 2. The sealing buffer cavity 10 is filled with an elastic sealing material, such as a pressure-resistant and corrosion-resistant composite rubber material, to absorb the stress at the connection and prevent fluid leakage. The width of the sealing buffer cavity 10 can be designed according to actual needs, for example, in the range of 1 to 3 mm, to ensure sufficient buffering effect.

[0023] The connecting plate 7 is designed as a double-layer structure, including a main support layer 11 and an auxiliary locking layer 12. The two layers are connected by an elastic connector 13, which can be a spring or a rubber pad to provide a certain buffering performance. The contact surfaces of the main support layer 11 and the auxiliary locking layer 12 are provided with interlocking teeth 18. When subjected to external pressure, the interlocking teeth 18 mesh with each other, thereby increasing the support strength and preventing the connecting plate 7 from deforming or loosening under high load.

[0024] The lead screw 9 is provided with an anti-loosening structure 14, which includes a locking nut 19 and an anti-loosening washer 20. The anti-loosening washer 20 is made of an elastic material, such as polyurethane or silicone, and has self-adaptive deformation characteristics. It can maintain the locking effect under vibration or temperature change environment. The anti-loosening structure 14 forms a linkage mechanism with the connecting plate 7. When the lead screw 9 rotates, the anti-loosening structure 14 can ensure the stability of the adjustment position and avoid adjustment failure due to loosening.

[0025] As shown in the figure, the outer wall of the conveying pipe 4 is provided with reinforcing ribs 17. The reinforcing ribs 17 are distributed along the axial or circumferential direction of the conveying pipe 4, and their shape matches the hook part of the connecting plate 7. For example, the reinforcing ribs 17 can be designed as a raised strip structure to form a snap-fit ​​with the hook, thereby increasing the connection stability and preventing the conveying pipe 4 from falling off under high pressure or vibration.

[0026] This innovative design addresses the technical problems of leakage and unstable connection that often occur during valve use. It primarily involves creating a sealing buffer cavity 10 between the locking nut 19 and the connecting pipe 2, filled with a pressure-resistant and corrosion-resistant elastic sealing material to effectively prevent media leakage. Simultaneously, the adjustment structure 5 enables flexible adjustment and stable support of the connection points. The double-layer connecting plate 7 and interlocking tooth 18 in the adjustment structure 5 enhance the support strength, while the anti-loosening structure 14 further ensures connection reliability. The reinforcing ribs 17 on the outer wall of the conveying pipe 4 match the hooks of the connecting plate 7, further improving connection stability. Overall, this invention significantly improves the safety and service life of the valve through multiple leak-proof and stable designs, making it suitable for various complex working conditions.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
