Product Description
This is a composite exhaust valve, which is mainly used in fluid
pipeline systems such as water supply and drainage, municipal
pipelines, and water conservancy projects to solve the problem of
gas accumulation in the pipeline and ensure the efficient and
stable operation of the system.
Key role: "Exhaust Guardian" of pipelines
Core Functions
- Exhaust air: Automatically exhausts air when pipeline is filled with water or
during long-term operation, preventing air blockage and improving
water flow efficiency
- Exhaust biogas/harmful gas: Discharges gases produced by organic decomposition in sewage
pipelines, preventing pipeline bursting and odor leakage
- Reduces water hammer risk: Protects municipal water supply mains from pressure surges after
exhaust
Structure & Principle
Valve body: Made of ductile iron with anti-corrosion spray treatment,
pressure-resistant and corrosion-resistant for buried/open-air
environments. Features bottom flange for easy pipeline connection.
Exhaust assembly: Consists of metal mesh (porous structure) and valve cover with
float + sealing mechanism. The float rises to close exhaust port
when pipeline is full of water, and drops to allow gas discharge
when pipeline is empty.
Application Scenarios
- Municipal water supply: Urban water supply mains, community secondary water supply
pipelines
- Sewage pipe network: Sewage treatment plant water inlet pipes, urban drainage mains
- Water conservancy projects: Irrigation channels, reservoir water pipelines
