Product Description

An exhaust valve is a device used to remove gas from a pipeline or closed system. It is mainly used to prevent air blockage (air accumulation affects fluid flow), improve system efficiency or avoid equipment damage. The following is a detailed introduction to the exhaust valve:
1. Main functions
- Exhaust air: Automatically or manually release air or other gases in the pipeline to ensure smooth flow of fluids (such as water, oil, and steam).
- Prevent vacuum: Some exhaust valves can inhale air when the system is emptied to avoid the formation of vacuum.
- Protect equipment: Reduce cavitation, water hammer and other phenomena, and extend the service life of components such as pumps and pipelines.
2. Common types
- Automatic exhaust valve:
- Float type: Use the float to control exhaust as the water level rises and falls, and the valve automatically opens to exhaust when air accumulates.
- Diaphragm type: The diaphragm is driven to open and close by changes in air pressure, suitable for small systems.
- Manual exhaust valve:
- Manual operation is required (such as knob or screwdriver to open), commonly found in radiators or local pipelines.
- Compound exhaust valve:
- Combines automatic exhaust and high-speed exhaust functions, suitable for high-pressure or large-flow systems (such as water supply networks).
- Vacuum breaker valve:
- Prevents pipe collapse or backflow due to negative pressure when the system is shut down.
3. Application scenarios
- Water supply system: Remove air from high-rise buildings and municipal pipes to avoid water hammer.
- Heating and ventilation system (HVAC)**: Exhaust air from radiators and floor heating pipes to ensure heating efficiency.
- Industrial pipeline: Gas-liquid separation in petroleum, chemical and other fields.
- Wastewater treatment: Exhaust of aeration tanks and water pipelines.
