Description

Technical Field

[0001] This utility model relates to the field of duckbill valve technology, and in particular to a novel duckbill valve structure. Background Technology

[0002] Duckbill valves, as a common fluid control element, are widely used in drainage, ventilation, and backflow prevention systems. Traditional duckbill valves typically consist of a valve seat and a conical nozzle, opening and closing via fluid pressure. However, existing duckbill valves still have several shortcomings in practical applications: First, the strip-shaped opening of the nozzle provides poor sealing under low pressure or reverse flow, easily leading to fluid leakage or backflow; second, the valve body structure is simple, lacking optimized flow guidance design, which can easily generate turbulence, especially under complex fluid conditions, reducing flow guidance efficiency; third, some duckbill valves use a split structure or are made of non-elastic materials, resulting in problems such as easy wear at the joints, insufficient corrosion resistance, and short service life. Furthermore, the sidewalls of the existing nozzle opening lack effective support structures, making them prone to fatigue deformation and failure after long-term use. Therefore, there is an urgent need for a duckbill valve with optimized structure, reliable sealing, and high durability to address the above-mentioned technical deficiencies. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a novel duckbill valve structure.

[0004] To achieve the above and other related objectives, the technical solution provided by this utility model is: a novel duckbill valve structure, including a duckbill valve body, the duckbill valve body including a valve seat and a valve nozzle, the valve seat being configured as a cylindrical structure, the valve nozzle being configured as a conical structure, the end of the valve nozzle being provided with a strip-shaped opening, and at least one set of correspondingly arranged protruding ridges being provided on the two opposite sidewalls of the strip-shaped opening.

[0005] The preferred technical solution is that the convex ridge is arranged along the flow direction of the valve nozzle.

[0006] The preferred technical solution is that the valve seat and the valve nozzle are integrally injection molded from silicone.

[0007] The preferred technical solution is that the protruding ridge is configured as a strip-shaped structure or a wavy structure.

[0008] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0009] 1. Enhanced sealing and backflow resistance: By setting convex ridges on the symmetrical sidewalls of the strip-shaped opening, the contact area and tightness of the valve nozzle when closed are significantly improved, effectively preventing leakage problems during low pressure or reverse flow.

[0010] 2. Optimize flow guiding performance: The convex ridges are arranged along the flow guiding direction of the valve nozzle, which can guide the fluid to form a stable laminar flow, reduce the generation of turbulence, thereby improving the flow guiding efficiency and reducing fluid resistance.

[0011] 3. Integrated molding and material advantages: The valve seat and valve nozzle are integrally injection molded with silicone, which not only simplifies the manufacturing process and reduces costs, but also improves the overall elasticity and corrosion resistance of the valve body and extends its service life.

[0012] 4. Structural flexibility and adaptability: The convex ribs can be designed as strips or waves to adapt to different flow and pressure conditions, further enhancing the versatility and reliability of the valve body. Attached Figure Description
