Kev Taw QhiaHauv cov txheej txheem tseem ceeb hauv qab dej hiav txwv, tsis muaj dab tsi tseem ceeb dua li kev ua kom ruaj khov ntawm cov qauv kom ntseeg tau tias Kev Ua Haujlwm. Hikelok subsea ball valves tau tsim los ua kom tau raws li qhov kev thov uas nce ntxiv hauv kev lag luam roj av nrog rau qhov xav tau rau cov khoom siv sab nraud hauv lwm lub khw. Siv cov thev naus laus zis tsim qauv zoo ib yam li lub pob valve txheem, kev tsim qauv hauv qab dej hiav txwv suav nrog kev hloov pauv tsim nyog los muab lub valve sab nraud txhim khu kev qha rau kev lag luam hauv qab dej hiav txwv.
Cov yam ntxwvYooj yim mounting rau ROV, diver lossis chaw taws teeb actuationSiab ua haujlwm siab tshaj plaws txog li 20,000 psig (1379 bar))Cov ntsaws ruaj ruaj ywj pheej rau kev sib txawv ntawm lub caij nplooj ntoos hlavTsim los ntawm kev kaw sab nraud rau qhov tob txog 15,000 feet (4572 meters)Ob chav thaiv o-rings kom tiv thaiv kev nkag mus ntawm dej hiav txwvSiab ua haujlwm siab tshaj plaws txog li 20,000 psig (1379 bar)316 stainless hlau ua haujlwm txias nrog PEEK rooj zaum yog tus qauvMuaj ntau yam khoom siv foobCov hlau tshwj xeeb muaj rau kev pabcuam hnyavMuaj rau NACE MR0175.eQhov loj ntawm kev sib txuas ntawm 3/16 "mus rau 1"
Cov txiaj ntsigKev ua haujlwm tig ib lub quarter sai sai muab kev qhib / kaw sai rau kev ua haujlwm ROV lossis diver yooj yimCov ntsaws ruaj ruaj ywj pheej rau kev sib txawv ntawm lub caij nplooj ntoos hlavTrunnion mounted pob tsim thiab blowout pov thawj qia rau kev nyab xeeb siab tshaj plawsTsim los ntawm kev kaw sab nraud rau qhov tob txog 14,000 feet (4200 meters)Yooj yim mounting rau ROV, diver lossis chaw taws teeb actuationMuaj peev xwm txuas qhov kawg uas hloov tau tsis txwv rau kev teeb tsa ntau yamOb chav thaiv o-rings lossis khob foob xaiv kom tiv thaiv kev nkag mus ntawm dej hiav txwvBi-directional fl ow peev xwmTxoj kev ntws puv nkaus los ntawm lub valve kom txo qhov siab poob
