pressure conduit
2.Drainage of conduit of the formation as a result of liver cirrhosis ascites and lymphatic loop obstacle, bosom not free has particular concern, in normal circumstance, place of joint of the vein inside pectoral conduit and neck has opposite mechanical sex stricture and valve, with slow down lymphatic the speed that flows into blood circulation and prevent blood to enter lymphatic upstream, it is normal physiology need, but when high pressure of liver cirrhosis portal vein, one of pathogenies that this one physiology anatomizes a structure to become heighten of portal vein internal pressure and ascites to form, reason undertakes pectoral conduit drainage and bosom guide be identical of the vein inside neck is reducing the effect with reduce esophagus to varicosity bleeds and improve ascites respect to have portal vein pressure, certain.
3.Cupreous conduit quality of a material sex of hard, compression is strong, although changeless also body leaves in high-pressured condition, not burst; At the same time because its function stability, corrosion resistance is strong, make obstruction of the flow inside the canal lesser, make sure current is expedite already the pressure that eases water to shed pair of tube wall again, this went up to be sure for water supply, OK and long-term safety is used and do not have trouble back at home.
4.On a loop conduit experimental installation,the pressure drop of watercut crude oil(WCCO) of Daqing 1st oil production factory with flow improver(FI) DODE added flown through a perforated tube 62 mm in diameter and 900 mm long,a pumping unit tube valve(TV) 55 mm in diameter,and a pumping unit pillar fill valve(PFV) 30 mm in diameter succesively is measured at 45℃.
5.And cupreous conduit quality of a material sex of hard, compression is strong, although changeless also body leaves in high-pressured condition, not burst; At the same time because its function stability, corrosion resistance is strong, make obstruction of the flow inside the canal lesser, make sure current is expedite already the pressure that eases water to shed pair of tube wall again, this went up to be sure for water supply, OK and long-term safety is used and do not have trouble back at home.
