Product Description

Wafer check valve is a compact and easy-to-install check valve, usually used to prevent fluid backflow. It is characterized by small size and light weight, and is suitable for installation in pipeline systems with limited space. The following is a detailed introduction to the wafer check valve:

1. Working principle
The wafer check valve realizes the check function by automatically opening and closing the valve disc:
- When the fluid flows forward, the fluid pressure pushes the valve disc to open, allowing the medium to pass.
- When the fluid stops or flows in the reverse direction, the valve disc quickly closes under the action of gravity or spring force to prevent the medium from flowing back.
The valve disc design of the wafer check valve is usually swing type or wafer type, and the impact force is small when closing, which can effectively reduce the water hammer effect.
2. Main features
- Compact structure: The wafer design makes it small and light, saving installation space.
- Easy to install: It is clamped between the pipe flanges by bolts, without the need for additional connectors.
- Low flow resistance: The flow channel design is optimized, the resistance when the fluid passes is small, and the energy consumption is low.
- Good sealing: Soft seal or metal seal is used between the valve disc and the valve seat to ensure good sealing performance.
- Wide range of application: It can be used for various media such as water, oil, gas, etc.
3. Application scenarios
Wafer check valves are widely used in the following fields:
- Water supply system: Prevent water backflow when the water pump stops, and protect the water pump and pipeline.
- HVAC system: Used to prevent hot or cold water backflow and maintain the normal operation of the system.
- Industrial pipeline In the chemical, petroleum, pharmaceutical and other industries, prevent the backflow of the medium from causing pollution or equipment damage.
-Fire protection system: Ensure that water does not flow back when the fire pump stops, and maintain the system pressure.
