Air vent valves include single-port air vent valves, double-port air vent valves, combination air vent valves, and high-speed air vent valves.
Single-port air vent valve:
Single-port air vent valves are used for venting air from pipes in independent heating systems, centralized heating systems, heating boilers, central air conditioning, underfloor heating, and solar heating systems. Because water usually contains dissolved air, and the solubility of air decreases as temperature increases, gas gradually separates from the water during circulation and gradually clumps together to form large bubbles or even air columns. Due to the replenishment of water, gas is frequently generated.
Double-port air vent valve:
Double-port air vent valves are suitable for pipelines containing water. They are devices used to remove gas from the pipeline, improving the efficiency of water supply equipment and protecting the pipeline from deformation and rupture. They are essential equipment for pipelines.
High-speed exhaust valve:
The high-speed dual-port exhaust valve is the most advanced cylinder-type exhaust valve in China. Its structural performance completely surpasses ordinary high-speed (dual-port) exhaust valves and composite dual-port exhaust valves. It can continuously and at high speed discharge gas from pipelines, regardless of whether there are multiple water columns, alternating air columns, or pressure. The float does not stick to the exhaust port, eliminating the problem of jamming.
