Lift type check valve plays a critical role in many industrial and civilian fields, providing reliable guarantees for the stable operation of various fluid conveying systems, thanks to its precise opening and closing response, excellent water hammer elimination ability, stable sealing performance, significant energy-saving advantages, and convenient maintenance characteristics.
In working scenarios where water pumps frequently start and stop,lift type check valve is an ideal choice. For example, in the municipal water supply system, the water pump needs to be continuously started and stopped according to water demand. Traditional check valves are prone to water hammer when the water pump stops, causing impact on pipelines and equipment,the lift type check valve achieves sealing through the axial lifting of the valve disc, effectively eliminating water hammer.
In seawater desalination projects, the sealing performance of valves is highly required,the lift type check valve adopts a metal elastomer composite sealing surface design, which can maintain a leakage standard of 0.01L/m during long-term operation and has excellent sealing performance. In the chemical industry, when transporting corrosive, toxic, harmful, or high-value fluids, its good sealing performance can prevent fluid leakage from causing safety accidents or material losses, ensuring production safety and environmental safety, while reducing maintenance costs and material losses.
In district heating systems and large air conditioning systems, the fluid flow rate is high, and strict requirements are placed on the flow resistance and energy efficiency of valves,the optimized flow channel design of the lift type check valve gives it low flow resistance characteristics, with a pressure loss of no more than 0.15 bar at rated flow, which is about 40% lower than similar products. In the renovation case of the district heating system, after replacing with a lift check valve, the annual power consumption of the system pump group was reduced by 72000 kilowatt hours, and the energy-saving effect was significant.
