JIS F 7356 Bronze 5K nqa kos valve yog lub valve siv nyob rau hauv marine engineering thiab shipbuilding teb. Nws yog ua los ntawm cov khoom siv tooj liab thiab ua tau raws li tus qauv ntawm 5K siab ntsuas. Nws feem ntau yog siv rau hauv cov raj xa dej uas yuav tsum tau kuaj xyuas.
Corrosion tsis kam: Bronze li qub muaj kev tiv thaiv corrosion zoo heev thiab tsim nyog rau thaj chaw marine.
Kev ntseeg siab: Lub lifting check valve tuaj yeem xyuas kom meej tias qhov nruab nrab yuav tsis ntws rov qab, ua kom muaj kev nyab xeeb ntawm lub cev.
Kev siv dav: tsim nyog rau kev ua haujlwm hauv dej hiav txwv thiab kev tsim nkoj nkoj, tshwj xeeb tshaj yog tsim nyog rau daim ntawv thov scenarios uas xav tau kev ua haujlwm tiv thaiv corrosion.
JIS F 7356 Bronze 5K nqa check valve feem ntau yog siv rau hauv cov kav dej hauv cov teb xws li nkoj, marine engineering, thiab offshore platforms los tiv thaiv qhov nruab nrab rov qab thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm. Nws lub hom phiaj tseem ceeb yog los ua kev tshawb xyuas hauv cov kav dej hauv cov dej hauv cov dej hiav txwv.
Lift design: Nrog lub tshuab nqa nqa, nws tuaj yeem tiv thaiv qhov rov qab ntws ntawm qhov nruab nrab.
Bronze khoom: Ua los ntawm cov khoom siv zoo bronze, nws muaj kev tiv thaiv corrosion zoo thiab yoog raws ib puag ncig seawater.
Ua raws li cov qauv: Ua raws li JIS F 7356 tus qauv, ua kom nws cov kev ua tau zoo thiab kev ua tau zoo raws li cov kev cai.
