Isebe lobuchwepheshe be-fluid le-BMG libonelela ngoluhlu olubanzi lwamacandelo kunye nenkxaso kwiinkqubo zobuchwepheshe be-fluid kunye nokusetyenziswa kwemizi-mveliso ngokubanzi. Ezi mveliso ziquka iivalvu, i-hydraulic hoses kunye nezinto zokufakelwa, i-accumulators, iisilinda, izitshintshi zobushushu, ii-motor hydraulic kunye nemibhobho ye-hydraulic, kunye neempompo kunye nezixhobo zetanki.
Iivalve ezibalulekileyo kwipotifoliyo yemveliso ye-BMG ziquka i-InterApp Bianca kunye ne-Desponia butterfly valves, ezicetyiswa ukuba zisetyenziswe ngokufanelekileyo nangokukhuselekileyo ekufuneni izicelo zokulawula ukuhamba kwezoshishino.
"Ivalve yebhabhathane erhabaxa yenzelwe ukuvala ngokuthembekileyo kwaye ilawule ulwelo olutshabalalisayo kunye nezicelo ezicocekileyo," utshilo uWillie Lamprecht, uMphathi weCandelo loShishino lweBMG Fluid Low Pressure. “Ivalve yebhabhathane ebambeneyo ineempawu zokuqukuqela okuhle kunye neemfuno zokulondolozwa okuphantsi, kwaye iguquguquka kakhulu, iqinisekisa ukusebenza okuthembekileyo nakweyona ndawo inzima.
“Ngokungafaniyo nevalve yebhola, idiski yevalve yebhabhathane isoloko ikhona kumjelo wokuhamba. Oku kuthetha ukuba kungakhathaliseki ukuba indawo yevalve, iya kubangela ukuhla koxinzelelo ekuhambeni. Iivalvu zebhola zingasetyenziselwa ukubekwa zodwa, ngelixa iivalve zebhabhathane zingasetyenziselwa ngokukhuselekileyo ukwahlula kunye nokulawula ukuhamba.
“Xa kuthelekiswa nezinye iintlobo, enye yeengenelo zokusebenzisa ivalve yebhabhathane ejikeleza ngasekunene yindlela elula emile okwe-wafer, iinxalenye ezimbalwa, ukulungiswa lula kunye nokulungiswa kancinci.”
Ivalve yebhabhathane ye-BMG ye-InterApp Bianca ifakelwe ilining ye-PTFE ehlala ixesha elide, inobomi obude benkonzo, kwaye ilungele ulwelo oludlekayo kunye nolwelo kunye nokusetyenziswa apho ukucoceka ngokupheleleyo kubaluleke kakhulu.
Ezi zivalo eziphezulu ziphakathi kwe-DN 32 kunye ne-DN 900 ngobukhulu kwaye zenziwe nge-ductile iron, i-carbon steel okanye i-stainless steel valve body ukuze ihlangabezane neemfuno zawo onke amashishini. Iivalve ze-butterfly ze-Bianca zinokucwangciswa ngabanye nge-BMG ukuqinisekisa ukusebenza okuthembekileyo kunye nokhuseleko olufanelekileyo kwizicelo ezithile.
Ngokomzekelo, i-valve ye-Bianca ehambelana ne-FDA (i-DN 50-DN 200) ine-disc ye-mirror-polished stainless steel disc kunye ne-high-purity PTFE lining ukuqinisekisa ukhuseleko lwemveliso yezinto ezisebenzayo zonyango. Iivalvu ze-Bianca ezine-PFA-coated discs kunye ne-PTFE lining ziyacetyiswa kwizicelo zeekhemikhali eziyingozi kakhulu.
Olu chungechunge lwee-valve lusebenzisa ii-discs ezikhethiweyo ezikhethiweyo kunye nezixhobo ze-lining, kwaye zihambelana nomyalelo wobungqina bokuqhuma kwe-ATEX 94 / 9EG, ukuqinisekisa ukusebenza okukhuselekileyo kwiindawo eziqhumayo.
Iimpawu eziphawulekayo zolu chungechunge lwe-Bianca lubandakanya i-bushings ephezulu, i-PFA disc overmolding kwi-shaft, kunye nezitywina zokhuseleko ezilayishwe kwangaphambili ebomini, ukuqinisekisa ukutywinwa okuthembekileyo kwe-shaft kunye nokutywinwa kwe-shaft okuhlala ixesha elide, nakwimijikelo enzima yokusebenza kunye namaqondo obushushu aphezulu.
I-cavity lining ikhusela ukuhamba okubandayo kwi-flange yokutywinwa kwendawo, ngaloo ndlela yandisa ubomi benkonzo, ngelixa i-PTFE i-lining idibene ne-PFA overmolded disc iqinisekisa i-friction ephantsi, ngaloo ndlela yandisa ubomi benkonzo yenkqubo. Ezinye iimpawu zibandakanya indlela yokutywina ishaft yangaphandle ukukhusela umngxuma wentamo yevalve kunye ne-robust self-lubricating kunye ne-bushing-free bushing. Iithegi zevalvu yentsimbi engenasici zivumela ukulandeleka ngokupheleleyo.
I-BMG igcina uluhlu olubanzi lwamacandelo agqityiweyo ukubonelela ngamaxesha amafutshane okuhanjiswa, nakwi-Bianca series kunye nobukhulu be-DN 900.
Ukusetyenziswa okuqhelekileyo kweevalvu zebhabhathane zeBianca kukutsalwa kweeasidi kunye nezinyibilikisi kwimigodi kunye nodaka; ukusetyenzwa okongeziweyo kwishishini leoli kunye negesi kunye neenkqubo ezonakalisa kakhulu kwishishini lentsimbi. Olu chungechunge lukwafanelekile kunyango lwamanzi apho ukungcola okuncinci kufuneka kugwenywe.
Iivalvu zebhabhathane ze-BMG ze-InterApp Desponia kunye neziko le-Desponia Plus zinomzimba owomeleleyo kunye nelinen eyomeleleyo ye-elastomer, kwaye ziyilelwe ulungelelwaniso olukhuselekileyo noluthembekileyo lolwelo neegesi kwiindawo ezahlukeneyo.
Iivalve ze-Desponia zifumaneka ngobukhulu ukusuka kwi-DN 25 ukuya kwi-DN 1600 kunye noxinzelelo ukuya kwi-bar ye-16, efanelekileyo kwizicelo ezahlukeneyo zoshishino. Olu luhlu lunokubonelela ngentsimbi etyhidiweyo kunye nemizimba ye-iron valve ductile.
Ubungakanani bechungechunge lwe-Desponia Plus luphakathi kwe-DN 25 kunye ne-DN 600, efanelekileyo kwizicelo zoxinzelelo oluphezulu ukuya kwi-bar ye-20, ifanelekile kwiqondo lokushisa eliphezulu okanye izicelo ze-vacuum kunye nenkqubo yokuzenzekelayo. Olu chungechunge lunokubonelela ngemizimba yevalvu eyenziwe ngentsimbi ye-ductile, intsimbi etyhidiweyo okanye intsimbi engatyiwa.
I-liner kunye ne-butterfly plate yolu chungechunge idlala indima ebalulekileyo kwi-valve ye-butterfly ene-elastic lined, kuba ngamalungu amabini kuphela adibana nolwelo. Iifowuni ze-Flucast® zifanelekile kwizicelo ezinobungozi kwaye zikwahambelana ne-FDA kunye nemimiselo ye-EU.
Iimpawu eziphawulekayo zolu chungechunge ziquka indlela yokutywina i-shaft yangaphandle ekhusela umngxuma wentamo yevalve kunye noyilo olude lwentamo oluvumela ukugquma kombhobho. I-gasket esisigxina inika ukhuseleko ekuphepheni, kwaye i-O-ring yakhiwe kwi-pasese ye-shaft ukuze ibe yinxalenye yenkqubo ethembekileyo yokutywinwa kwe-shaft.
Umlebe wokutywina kumphezulu we-flange ubonelela ngesitywina esigqibeleleyo, kwaye imilo ephuculweyo ye-lining iqinisekisa ukubamba ngokuchanekileyo emzimbeni. I-disc ye-square drive inika ukuhanjiswa kwe-torque esebenzayo kunye nexesha elide, kwaye umda we-disc wokupolisha unciphisa ukungqubana.
Uchungechunge lweDesponia luqinisekisa ukusebenza okukhuselekileyo kwiinkqubo zokunyanga amanzi, ukuveliswa kwamandla kunye nokufunwa kwezicelo zonyango lwekhemikhali. Ezi zivalo ziyakwazi ukumelana nokusebenza kwishishini lentsimbi, apho iivalve ezivaliweyo ezisetyenziselwa ukufunxa intsimbi etyhidiweyo zibonakaliswe kwiimeko ezinzima. Ezi zivalo ezineediski ezidityanisiweyo ngokukodwa zifanelekile kwimigodi kunye nodaka, kwaye zisetyenziselwa iinkqubo zokukhupha ezifuna iivalve ezinobuxhakaxhaka obuphezulu bokunxiba kunye nokuxhathisa ukubola.
