Kev txhim kho li qub hauv dej hiav txwv yuav tsum tau ua tib zoo xav txog ntau yam kom ntseeg tau tias lub valve ua tau zoo thiab kav ntev rau qhov chaw hnyav no. Qee qhov tseem ceeb rau kev txhim kho li qub hauv dej hiav txwv yog:
Kev xaiv cov khoom siv: Cov khoom siv valve yuav tsum tiv taus corrosion los ntawm seawater, uas muaj cov ntsev ntau ntau thiab lwm yam minerals. Cov khoom siv feem ntau siv rau cov dej hiav txwv muaj xws li tooj liab, tooj dag, stainless hlau, thiab titanium.
Coatings: Qee cov li qub yuav xav tau cov txheej txheem tshwj xeeb los tiv thaiv lawv los ntawm corrosive los ntawm dej hiav txwv. Cov txheej txheem muaj xws li epoxy thiab lwm yam txheej txheej polymer.
Tsim: Lub valve yuav tsum tau tsim los txo qis fouling thiab clogging los ntawm seaweed, barnacles, thiab lwm yam marine kab mob. Qhov no tuaj yeem ua tiav los ntawm kev siv cov qauv tsim kom yooj yim thiab du nto.
Kev Kho: Kev saib xyuas tsis tu ncua thiab tshuaj xyuas yog qhov tseem ceeb kom ntseeg tau tias lub valve tseem nyob hauv qhov zoo. Qhov no yuav suav nrog kev tu thiab tshem tawm kev loj hlob hauv hiav txwv thiab hloov cov khoom hnav lossis puas.
Kev Ntsuas: Cov li qub yuav tsum tau kuaj xyuas kom zoo ua ntej kev teeb tsa kom ntseeg tau tias lawv tuaj yeem tiv taus qhov siab thiab ntws ntawm cov dej hiav txwv.
Kev teeb tsa: Cov Valves yuav tsum tau teeb tsa los ntawm cov kws tshaj lij uas paub txog cov kev sib tw tshwj xeeb ntawm kev ua haujlwm hauv ib puag ncig marine. Kev saib xyuas tshwj xeeb yuav tsum tau ua kom ntseeg tau tias lub valve raug thauj khoom kom zoo thiab kaw kom tsis txhob xau.
Los ntawm kev ua raws li cov kev cai no, li qub tau teeb tsa hauv dej hiav txwv tuaj yeem muab kev ntseeg tau thiab ua haujlwm tau zoo rau lub sijhawm ntev.
