Using a special type of axial-flow check valve, in order to ensure the safe and efficient operation of equipment, piping systems

With the large domestic oil refining and ethylene and other petrochemical projects and the new expansion , long-distance oil and gas pipeline systems and large ethylene plant compressors and large pumps and other working conditions more demanding pipeline system that requires selection of quick closing , low pressure loss and noise valve. Especially the gas medium , for ordinary swing , dual plate check valves,  High pressure ball valve  is often not fully open , resulting in medium flow instability, pressure loss , prone to mechanical vibration , noise, large , etc., thus  Needle valve  a large compression the normal operation of the pump unit . Then you need to use a special type of axial flow check valve, in order to ensure the safe and efficient operation of equipment and pipeline systems . Axial quick closing check valve function . Axial flow check valve and swing , dual plate check valve , compared short trip, especially the relatively large  Check valve  stroke is shorter , you can achieve rapid closure . The fluid system the damaging effects of water hammer to a minimum. Axial flow check valve closed completely along with the reverse flow of fluid , short stroke valve ensures fast dynamic response, and reverse flow through the valve to a minimum , thereby preventing the risk of water hammer phenomenon occurs . Turn to protect equipment from damage caused by fluid backflow . Can completely prevent the media back cause upstream device damage.
