exhaust valve

An exhaust valve is a device used to eliminate gas from pipelines, widely applied in various pipeline systems such as tap water transmission pipelines in urban water plants, independent heating systems, central heating systems, heating boilers, central air conditioning, floor heating, and solar heating. The primary working principle and function of the exhaust valve produced by Zhejiang Shanliu is to prevent gas accumulation in pipelines, enhance pipeline efficiency, and reduce energy consumption. There are various types of exhaust valves, primarily including: single-port exhaust valves for exhausting gas in independent heating systems, central heating systems, heating boilers, central air conditioning systems, floor heating systems, and solar heating systems; double-port exhaust valves suitable for pipelines with water as the medium, serving as a device to eliminate gas from pipelines, thereby enhancing the efficiency of water conveyance equipment and protecting pipelines from deformation and rupture; quick exhaust valves, the most advanced cylinder-type exhaust valves in China, capable of continuously and rapidly exhausting gas from pipelines, applicable to various pipeline environments; and composite exhaust valves suitable for complex pipeline systems requiring the removal of large amounts of gas.
