Why does the medium flow axially from the inlet to the outlet in the dispensing valve?

1. Role of the Dispensing Valve in Industrial Applications
Precision and Control: The Dispensing valve is essential for delivering materials like sealants and adhesives with high precision and control. This is particularly important in industries where accuracy is paramount, such as automotive, electronics, and construction.
Versatility: The valve can handle a wide range of materials, making it a versatile tool in various industrial settings. Its ability to maintain consistent flow rates ensures reliable performance across different applications.

2. Components of the Dispensing Valve
Rotor Design: The rotor is a critical component with a unique geometry. It features a large pitch, high teeth, and a small spiral diameter. The cross-section of the rotor combines a half-circle and two-thirds of an ellipse, which is crucial for its functionality.
Stator Configuration: The stator is a double or triple-threaded spiral sleeve that complements the rotor. Its design ensures that the chambers formed between the rotor and stator walls move the medium forward in an axial direction.

3. Interaction Between Rotor and Stator
Chamber Formation: When the rotor rotates within the stator, it creates a series of chambers. These chambers sequentially fill with the medium as it enters the pump at the inlet. The interaction between the rotor and stator is key to this process.
Axial Movement: The movement of the medium is axial, meaning it progresses along the length of the pump from the inlet to the outlet. This is facilitated by the stator's spiral configuration, which ensures that the chambers maintain a consistent volume as they move.

4. Mechanism of Axial Movement
Rotor Rotation: The axial movement of the medium is driven by the rotation of the rotor. As the rotor turns, it pushes the medium forward through the stator. This rotation is continuous, ensuring a steady flow of the medium.
Medium Flow: The medium is drawn into the pump at the inlet, fills the chambers created by the rotor and stator, and is then pushed out at the outlet. This process is continuous and ensures a steady flow of the medium, which is crucial for applications that require precise and consistent delivery.

5. Importance of Consistent Volume
Volume Maintenance: The stator's spiral configuration ensures that the chambers maintain a consistent volume as they move. This is essential for the precise and controlled delivery of the medium. Any variation in volume could lead to inconsistencies in the flow rate, which could impact the quality of the application.
Reliability: The consistent volume of the chambers contributes to the reliability of the Dispensing valve. It ensures that the medium is delivered accurately and consistently, which is crucial for maintaining the quality and performance of the final product.

6. Applications and Performance
Wide Range of Applications: The Dispensing valve's ability to provide accurate and reliable performance makes it suitable for a wide range of industrial applications. Its design ensures that it can handle various materials with precision and control.
Foundation of Performance: The mechanism of the Dispensing valve, which leverages the interaction between the rotor and stator, is the foundation of its ability to provide accurate and reliable performance. This makes it an essential tool in industries that require high precision and consistency in material delivery.
