Product Overview

This product is a hydraulic control assembly device that strictly restricts the one-way flow of pressurized water in pipelines. Its function is to prevent the medium in the pipeline from flowing backward under all operating conditions, so as to avoid backflow contamination.

Main Features

• Designed for single diaphragm structure, ensuring reliable backflow prevention.
• Features low flow resistance, minimizing pressure loss in pipelines.
• Specifically engineered to prevent medium backflow and avoid backflow contamination.
• Suitable for controlling pressurized water in pipelines, adapting to various operating conditions.

Working Principle

1. When the pipeline has normal forward water pressure, the pressure pushes the diaphragm open, allowing water to flow forward smoothly.

2. If backflow tends to occur (e.g., downstream pressure is higher than upstream), the reverse pressure acts on the diaphragm, forcing it to close tightly.

3. The closed diaphragm blocks the water flow channel, thereby preventing the medium in the pipeline from flowing backward and avoiding backflow contamination.

Structural Features

• Adopts a single-diaphragm core structure as the key component for backflow prevention, ensuring sensitive and reliable action.
• Features a streamlined internal flow channel design, which helps reduce flow resistance and lower pressure loss during operation.
• Equipped with standard pipeline connection interfaces, facilitating easy installation and compatibility with common pipeline systems.
• Has a compact overall structure, occupying small space and suitable for limited installation environments.

Maintenance

• Check hydraulic oil level annually
• Test closing time every 6 months
• Inspect disc and seat for wear during system shutdowns
• Lubricate adjustment mechanism yearly
• Verify proper operation after system pressure changes
