Ivalve yePlag vsIvalve yeBhola: Usetyenziso kunye neemeko zokuSebenzisa
Ngenxa yokulula kwabo kunye nokuqina kobudlelwane, iivalve zebhola kunyeiivalve zeplagizombini zisetyenziswa kakhulu kuluhlu olubanzi lweenkqubo zemibhobho.
Ngoyilo olupheleleyo oluvumela ukuhamba kweendaba ezingathinteliyo, iivalve zeplagi zihlala zisetyenziselwa ukuthutha i-slurries, kuquka udaka kunye nogutyulo. Bakwabonelela nge-bubble-tight shutoff yolwelo, igesi kunye nemidiya yomoya. Ukuba bomeleziwe, amandla abo asele evaliwe anokubonelela ngetywina elivuzayo ngokuchasene nemithombo yeendaba eyonakalisayo. Ubulula babo kunye neempawu ezichasayo ukubola zibenza bathembeke kakhulu kwizicelo apho ukukhawuleza, ukuvalwa okuqinileyo kubalulekile.
Iivalvu zebhola zikwabonelela ngokuvalwa okungagungqiyo kweqam kwiinkonzo zolwelo ezifana nomoya, irhasi, umphunga, ihydrocarbon, njl njl. Ithandwa kuxinzelelo oluphezulu kunye neenkqubo zobushushu obuphezulu, iivalvu zebhola zifumaneka kwimigca yegesi, kwizityalo ze-oyile ekrwada, kwiifama zetanki, kwi-oyile. iindawo zokucokisa kunye nezicelo zenkqubo ezenzekelayo. Iivalvu zebhola ezinemilinganiselo ephezulu yoxinzelelo zinokufumaneka kwiinkqubo ezingaphantsi komhlaba kunye ne-subsea. Zikwadumile kwizicelo zococeko ezinje ngezonyango, amayeza, i-biochemical, ukwenziwa kwebhiya kunye nokutya kunye nesiselo.
Loluphi uhlobo lweValufa oluLungileyo kwiSicelo sakho?
Umsebenzi kunye noyilo lweeplagi kunye neebhola zebhola - kunye nokungafani phakathi kwazo - zichanekile ngokuthe tye, kodwa zihlala zinceda ukuthetha neengcali ezinokukukhokela ngendlela efanelekileyo.
Ngamafutshane, ukuba ufuna ivalve yokuvula/yokuvala usetyenziso loxinzelelo olusezantsi ukuya kwephakathi, ivalve yeplagi iya kubonelela ngokukhawuleza, ukuvuza okungagungqiyo. Kwizicelo zoxinzelelo oluphantsi ukuya kuxinzelelo oluphezulu (ingakumbi ezo zigcina i-torque encinci ibaluleke kakhulu), iivalve zebhola ziyisisombululo esithembekileyo, esilula ukusebenza. Kukho izinto ezikhethekileyo kuzo zonke iimeko, kodwa ukuziqhelanisa neempawu zabo ezithile kunye neemeko zokusetyenziswa ezicetyiswayo yindawo elungileyo yokuqala.
