Xa ukhetha ivalvu efanelekileyo kwiinkqubo zemibhobho yemizi-mveliso, yezolimo, okanye yezorhwebo, ukuqonda umahluko phakathiiivalvu zebhabhathane ze-lugkwayeiivalvu zebhabhathane ezijijekileyo ezimbinikubalulekile. Zombini iivalvu zisetyenziswa kakhulu kunyango lwamanzi, ukucubungula iikhemikhali, i-HVAC, kunye nemizi-mveliso yeoyile negesi ngenxa yoyilo lwazo oluncinci, ukusebenza kakuhle kweendleko, kunye nolawulo lokuhamba kwamanzi olusebenzayo. Nangona kunjalo, uyilo lwazo lwesakhiwo, iindlela zokufakela, kunye neemeko zokusetyenziswa ziyahluka, okwenza nganye ifaneleke kwiimeko ezithile. Eli nqaku lihlola umahluko ophambili, izibonelelo, iingxaki, kunye nokusetyenziswa kweevalvu zebhabhathane ze-lug kunye ne-double flange ukukhokela inkqubo yakho yokwenza izigqibo.
1. I-Lug Butterfly Valve: Uyilo kunye neempawu
Iivalvu zebhabhathane zeLug zibonakaliswa zii-inserts ezinemisonto, okanye "ii-lugs," emzimbeni wevalvu, ezivumela ukubotshwa ngqo kwiiflange zepayipi. Olu yilo lusebenzisa iiseti ezimbini zeebholiti ezizimeleyo ezingenamantongomane, njengoko iibholiti zibotshwa ngqo kwii-lugs. Olu lungiselelo lufanelekile kwiisicelo zokuphela komgca, apho icala elinye lombhobho linokususwa ngaphandle kokuchaphazela elinye.
Iimpawu eziphambili zeLug Butterfly Valves
- IiLugs ezinemisonto: IiLugs zibonelela ngeendawo zokufakelwa eziqinileyo, zivumela ivalvu ukuba ibotshelelwe ngokuzimeleyo kwiflange nganye yombhobho.
- Uyilo oluncinci: Lula kwaye lufutshane, iivalvu zelug zonga indawo, zilungele iinkqubo ezinesithuba esilinganiselweyo.
- Ukuhamba kweendlela ezimbini: Iivalvu zelug ezitywiniweyo ezithambileyo zixhasa ukuhamba kweendlela zombini, zibonelela ngokuguquguquka.
- Ukulungiswa okulula: Ulwakhiwo lwe-lug luvumela ukuba icala elinye lombhobho lisuswe ukuze lilungiswe ngaphandle kokuchaphazela elinye.
- Uvavanyo loxinzelelo: Ngokwesiqhelo lufanelekile kwii-applications zoxinzelelo oluphantsi ukuya koluphakathi, nangona uvavanyo loxinzelelo lunokuncipha kwinkonzo yokuphela komgca.
- Ukuguquguquka kwezinto: Zifumaneka kwizinto ezifana nentsimbi ethambileyo, i-WCB, okanye intsimbi engatyiwayo, kunye nezihlalo ezifana ne-EPDM okanye i-PTFE yokumelana neekhemikhali.
2. Ivalvu yebhabhathane ephindwe kabini: Uyilo kunye neempawu
Iivalvu zebhabhathane ezineeflange ezimbini zineeflange ezidityanisiweyo kuzo zombini iziphelo zomzimba wevalvu, zibotshelelwe ngqo kwiiflanges zepayipi ezifanayo. Olu yilo luqinisekisa uqhagamshelo olungavuziyo, nto leyo eyenza ukuba ifaneleke ukusetyenziswa koxinzelelo oluphezulu nobukhulu obukhulu. Ulwakhiwo lwayo oluqinileyo lumelana namandla abalulekileyo.
Iimpawu eziphambili zeValve zeButterfly eziBini zeFlange
- Iiflanges eziDibeneyo: Iiflanges kuzo zombini iziphelo ziqhagamshelana neeflanges zepayipi ngeebholiti, ukuqinisekisa ukulingana okuqinileyo.
- Ulwakhiwo Oluqinileyo: Lwenziwe ngezinto ezihlala ixesha elide ezifana ne-WCB, i-ductile iron, okanye intsimbi engagqwaliyo.
- Utywino Oluphezulu: Uyilo lweFlange luqinisekisa utywino oluqinileyo, lunciphisa umngcipheko wokuvuza kwizicelo ezibalulekileyo.
- Ukuhamba kweendlela ezimbini: Njengeevalvu ze-lug, iivalvu ze-flange ezimbini zixhasa ukuhamba kweendlela zombini.
- Ububanzi obukhulu: Ingamela ububanzi obukhulu xa ithelekiswa neevalvu ze-lug.
3. I-Lug Butterfly Valve vs. I-Double Flange Butterfly Valve
Ukuze wenze ukhetho olunolwazi, ukuqonda umahluko ophambili phakathi kwe-lug kunye ne-double flange butterfly valves kubalulekile. Apha ngezantsi kukho uthelekiso oluneenkcukacha lwezinto ezibalulekileyo:
3.1 Iimpawu Eziqhelekileyo
- Ukuguquguquka kofakelo: Zombini zivumela icala elinye lombhobho ukuba liqhawulwe ngaphandle kokuchaphazela elinye, zilungele iinkqubo ezifuna ukulungiswa rhoqo okanye ukwahlulwa kwecandelo.
- Ixabiso Xa lithelekiswa neeValve zeWafer: Ngenxa yee-lugs ezinemisonto okanye iiflange ezimbini, zombini zibiza kakhulu kuneevalve zewafer.
- Iimpawu Ezabelwana Ngazo:
- Inkxaso Yokuhamba Kwendlela Eya Kumacala Ababini: Zombini iintlobo zeevalvu zilungele ukuhamba kwendlela eya kwicala ngalinye, zilungele iinkqubo ezineendlela zokujikeleza kolwelo eziguquguqukayo.
- Uhlobo lwezinto: Zombini zingenziwa ngezinto ezifanayo ezifana nentsimbi yekhabhoni, intsimbi ethambileyo, okanye intsimbi engatyiwayo, kunye nezihlalo (umz., i-EPDM okanye i-PTFE) ezenzelwe ulwelo olufana namanzi, iikhemikhali, okanye iigesi.
