Kwintsimi enkulu yobunjineli bezoshishino, ukufumana iivalve ezisebenzayo nezithembekileyo zihlala ziphambili.Phakathi kweenketho ezininzi ezikhoyo, ivalve enye ibalasele ngokusebenza kwayo okuphezulu kunye nokuqina - i-Fluorine Butterfly Valve.Eli nqaku lijolise ekucaciseni iimpawu, iinzuzo kunye nokusetyenziswa kwesi sivalo esiphawulekayo esiye saba sisisombululo senguqu kwiinkalo ezahlukeneyo zoshishino.
Ivalve yebhabhathane ene-fluorine yivalve esebenzisa idiski efakwe kwishaft ejikelezayo ukulawula ukuhamba kolwelo ngombhobho okanye umbhobho.Eyodwa kule valve kukwakhiwa kwayo, ebonisa indawo yangaphakathi ene-fluoropolymer.Ngokuqhelekileyo zenziwe ngezinto ezifana ne-PTFE (i-polytetrafluoroethylene), le liner inokuxhathisa ngokugqwesileyo kwiikhemikhali ezinobundlobongela, ubushushu obuphezulu kunye nezixhobo ezinqabileyo.
Enye yeenzuzo eziphambili zeevalve zebhabhathane ezine-fluorine kukumelana nokubola.Iivalvu zemveli ezenziwe ngeentsimbi ezifana nentsimbi okanye intsimbi zidla ngokuwohloka ngokuhamba kwexesha ngenxa yokusabela kweekhemikhali xa uphethe ulwelo oludlekayo okanye iigesi.Umbane we-fluoropolymer wevalve yebhabhathane ithintela ukunxibelelana ngokuthe ngqo kwemithombo yeendaba ezonakalisayo kunye nesixhobo sevalve, iqinisekisa ubomi benkonzo kunye nokunciphisa iindleko zokugcina.
Ukongeza, ukumelana nobushushu obuphezulu bevalve yebhabhathane ene-fluorine nayo ikufanele ukuhoywa.Kwiinkqubo ezininzi zoshishino, ukuphathwa kwamanzi kubandakanya izinto ezishushu kakhulu, ezinokuchaphazela kakhulu ukusebenza kweevalvu zendabuko.I-fluoropolymer liner isebenza ngokufanelekileyo njengesithintelo sokushisa, ukukhusela i-valve emonakalweni wokushisa kunye nokugcina ukusebenza kwayo phantsi kweemeko zokushisa ezigqithiseleyo.
Ukomelela okugqwesileyo kwevalve yebhabhathane ene-fluorine kuyenza ilungele usetyenziso olubandakanya imathiriyeli yokurhawuka.Iinkqubo ezininzi zemizi-mveliso zifuna ukuphatha amasuntswana aqinileyo, anokuthi abangele ukugqoka okuphezulu kunye nokukrazula kwiivalve eziqhelekileyo.Iilayini zeFluoropolymer zibonelela ngokugqwesileyo kokunxiba, ziqinisekisa ubomi obude bevalvu kunye nokunciphisa imfuno yokutshintshwa rhoqo okanye ukulungiswa.
Ukuguquguquka kwevalve yebhabhathane ene-fluorine yenye inzuzo eyahlula kwiimveliso ezifanayo.I-valve ingasetyenziselwa kuluhlu olubanzi lwezicelo zoshishino ezibandakanya ukulungiswa kweekhemikhali, ioli kunye negesi, unyango lwamanzi kunye namayeza.Ukukwazi kwayo ukuphatha iintlobo ezahlukeneyo zolwelo, iikhemikhali ezinobundlongondlongo kunye neemeko zokusebenza ezirhabaxa ziyenza ilungele amashishini aneemfuno ezahlukeneyo.
Ukongeza, uyilo lwevalve yebhabhathane ye-fluorine inokuqonda ulawulo oluthembekileyo noluchanekileyo lokuhamba.I-disc yayo ijikeleza kwi-axis yayo, ivumela uhlengahlengiso olukhawulezayo nolusebenzayo lokuhamba.Olu phawu luluncedo ngakumbi apho kufuneka ummiselo ochanekileyo wokuhamba kwamanzi, njengezityalo ezixuba amayeza okanye iindawo zokucocwa kwamanzi amdaka.
Iivalve ze-butterfly ezine-fluorine zibonelela ngokulula kunye neendleko-zokusebenza xa kufikwa kunye nokugcinwa.Ukwakhiwa kwayo okulula kwenza kube lula ukuphatha nokufaka, ukunciphisa ixesha lofakelo kunye neendleko zabasebenzi.Ukongezelela, iipropathi ezichasene ne-stain-resistant ze-liner zinciphisa imfuno yokucoca rhoqo, ukunciphisa iimfuno zokugcinwa kunye nokunciphisa ukusebenza.
Nangona iivalve ze-butterfly ze-fluorine zineenzuzo ezininzi, kuyafaneleka ukuba uqaphele ukuba i-fluorine butterfly valves ayinayo imida.Inokuba namandla oxinzelelo oluphezulu olulinganiselweyo xa kuthelekiswa nezinye iindidi zevalve, ezinokunciphisa ukusetyenziswa kwayo kwezinye iimeko apho ukutywinwa koxinzelelo oluphezulu kubaluleke kakhulu.Nangona kunjalo, xa isetyenziswe ngaphakathi kwinqanaba loxinzelelo oluchaziweyo, i-valve ibonakalise ukuba iyisisombululo esithembekileyo nesisebenzayo.
Ukuqukumbela, iivalve zebhabhathane ezine-fluorine zibonelela ngesisombululo soguqulo kwizicelo zamashishini.Ukumelana ne-corrosion, ukumelana nobushushu obuphezulu kunye nokuqina kuyenza ibe lolona khetho lubalaseleyo lokuphatha ulwelo oludlekayo, amaqondo obushushu agqithisileyo kunye nezinto ezirhabaxa.Ngokuguquguquka kwayo, ulawulo oluchanekileyo lokuhamba kunye nokulula kokugcinwa, le valve ibe sisixhobo esixabisekileyo kumashishini ahlukeneyo.Ngenkqubela phambili yetekhnoloji kunye nophuhliso oluqhubekayo lweemfuno zeshishini, iivalve zebhabhathane ezine-fluorine ngokungathandabuzekiyo ziya kudlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kunye nokuthembeka kweenkqubo zokulawula ulwelo.
