Product details

This is a mini valve seal specifically designed for small household appliances. With its compact size and adaptability, it can be accurately embedded into the fluid control modules of small home appliances. Its core working logic revolves around intelligent response to fluid flow direction: when fluid flows in the forward direction, it generates a certain thrust to make the valve nozzle open naturally, ensuring smooth fluid passage. However, once the fluid supply stops or there is a tendency for reverse flow, the valve nozzle will quickly close tightly under the action of its own crimped structure, forming a tight seal. This can effectively block the backflow of media such as water and liquid medicine, prevent damage to internal components or functional failures of home appliances caused by media backflow, and provide key support for the reliability of fluid control in small household appliances.

Product Features:

1、Reliable One-way Sealing: It strictly fulfills the one-way valve function of "forward flow and reverse sealing". Through rigorous structural design, precise dimensional tolerances, and its own elastic deformation and rebound performance, it ensures that the valve lip fits tightly with the valve body or the inner wall of the pipeline, achieving sealing reliability. This strictly blocks the reverse leakage of liquid/gas, avoiding functional failures caused by internal water accumulation and backflow of equipment, and is an essential component in check valve systems and Sealed Fluid Direction Control Valve assemblies.

2、Adaptability to Low Opening Pressure: Small household appliances have low power and low fluid pressure. This Duckbill Valve achieves low opening pressure by optimizing the thickness and angle design of the lip, ensuring that it can open smoothly under slight pressure without affecting the equipment flow. It is well-suited for Sealed Diaphragm Pump and Sealed Fluid Transfer Pump setups in small appliances.

3、Resistance to Medium Erosion: According to the working environment of small household appliances, corresponding medium-resistant materials are selected or special formulas are adopted to achieve the ability to resist medium erosion, maintaining stable performance in Sealed Pump and Sealed Valve applications.

4、Meeting the Lightweight Requirements of Small Appliances: Due to the compact internal space of small household appliances, the Duckbill Valve needs to be small in size, light in weight, and low in material density. It not only does not increase the burden on the equipment but also realizes its one-way sealing function, making it compatible with Micro Sealed Hydraulic Pump structures.

5、Food-grade Safety: For some equipment that comes into contact with drinking water and food materials, materials that meet food contact safety standards (such as FDA certification), have no peculiar smell, and no harmful substances precipitated are selected to avoid contaminating the medium, aligning with the safety demands of Sealed Fluid Transfer Pump systems in food-related applications.
