Iivalvu zesango kunye neevalvu zebhabhathane ziivalvu ezimbini ezisetyenziswa kakhulu. Zahluke kakhulu ngokwezakhiwo zazo, iindlela zokusetyenziswa, kunye nokuzivumelanisa neemeko zokusebenza. Eli nqaku liza kunceda abasebenzisi baqonde ngcono umahluko phakathi kweevalvu zesango kunye neevalvu zebhabhathane. Nceda abasebenzisi bakhethe iivalvu ngcono.
Ngaphambi kokuba sichaze umahluko phakathi kwevalvu yesango kunye nevalvu yebhabhathane, makhe sijonge iinkcazo zazo zombini. Mhlawumbi ungawufumana ngononophelo umahluko phakathi kwezi zimbini kwinkcazo.
Ivalvu yesango,njengoko igama lisitsho, inganqumla i-medium ekwipayipi njengesango, kwaye luhlobo lwevalvu esiyisebenzisayo sonke kwimveliso nasebomini. Inxalenye yokuvula nokuvala yevalvu yesango ibizwa ngokuba yisango, kwaye isango lihamba linyuka lize lihle, kwaye ulwalathiso lwayo lokuhamba luthe nkqo kwicala lokuhamba kwe-medium ekwipayipi yamanzi; ivalvu yesango yivalvu enqunyulweyo, enokuvulwa ngokupheleleyo okanye ivalwe ngokupheleleyo, kwaye ukuhamba kwayo akunakulungiswa.
Ivalvu yebhabhathane, eyaziwa ngokuba yivalvu yeflap.Inxalenye yayo yokuvula nokuvala yipleyiti yebhabhathane emilise okwediski, enamathele kwisiqu sevalvu kwaye ijikeleza isiqu sevalvu ukuze ivuleke kwaye ivale. Indlela yokuhamba kwevalvu yebhabhathane kukujikeleza endaweni yayo, kwaye kufuneka ijikeleze kuphela i-90° ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo. Ukongeza, ipleyiti yebhabhathane yevalvu yebhabhathane ngokwayo ayinakho ukuzitshixa, kwaye kufuneka kufakwe isixhobo sokunciphisa izixhobo zemibungu kwisiqu sevalvu. Ngayo, ipleyiti yebhabhathane inokukwazi ukuzitshixa, kwaye inokuphucula ukusebenza kwevalvu yebhabhathane.
ukuba siyaqonda iinkcazo zeevalvu zesango kunye neevalvu zebhabhathane,vumela's zisa umahluko phakathi kweevalvu zesango kunye neevalvu zebhabhathane:
1. Umahluko kubuchule bezemidlalo
Kule nkcazo ingasentla, siyaqonda umahluko kwicala kunye nendlela yokuhamba kweevalvu zesango kunye neevalvu zebhabhathane. Ukongeza, iivalvu zesango zinokuvulwa ngokupheleleyo kwaye zivalwe ngokupheleleyo, ngoko ke xa zivulwe ngokupheleleyo, ukumelana nokuhamba kweevalvu zesango kuncinci; Iivalvu zebhabhathane Kwimeko evulekileyo ngokupheleleyo, ubukhulu bevalvu yebhabhathane bubangela ukumelana nendawo egelezayo. Ukongeza, ivalvu yesango inokuphakama okuphezulu kokuvula, ngoko ke isantya sokuvula nokuvala sicotha; ngelixa ivalvu yebhabhathane inokuvulwa kwaye ivalwe ngokujikeleza kuphela i-90°, ngoko ke isantya sokuvula nokuvala sikhawuleza.
2. Umahluko kwimisebenzi kunye nokusetyenziswa kwayo
Iivalvu zesango zisebenza kakuhle ekutywineni, ngoko ke zihlala zisetyenziswa kwiipayipi ezifuna ukuvalwa okungqongqo kwaye akufuneki zivulwe kwaye zivalwe rhoqo ukuze kunqunyulwe i-circulating medium. Ivalvu yesango ayinakusetyenziswa ukulawula ukuhamba. Ukongeza, ngenxa yokuba isantya sokuvula nokuvala kwevalvu yesango sicotha, ayifanelekanga kwiipayipi ezifuna ukuvalwa okungxamisekileyo. Ukusetyenziswa kweevalvu zebhabhathane kubanzi kakhulu. Iivalvu zebhabhathane azinakusetyenziswa kuphela ekunqunyulweni, kodwa zinomsebenzi wokulungisa isantya sokuhamba. Ukongeza, ivalvu yebhabhathane iyavula kwaye ivalwe ngokukhawuleza kwaye inokuvulwa kwaye ivalwe rhoqo. Ifanelekile ngakumbi ukusetyenziswa kwiimeko ezifuna ukuvulwa okanye ukuvalwa ngokukhawuleza.
Iivalvu zebhabhathane zincinci ngobukhulu kwaye zilula ngobunzima kuneevalvu zesango, ngoko ke kwezinye iindawo ezinesithuba esincinci sokufakelwa, kucetyiswa ukusebenzisa ivalvu yebhabhathane ye-wafer egcina indawo. Phakathi kweevalvu ezinkulu, iivalvu zebhabhathane zezona zisetyenziswa kakhulu. Iivalvu zebhabhathane zikwacetyiswa ekuthuthweni kwemibhobho yemidiya enezinto ezincinci.
Ngokuphathelele ukukhethwa kweevalvu phantsi kweemeko ezininzi zokusebenza, iivalvu zebhabhathane ziye zatshintsha kancinci ezinye iintlobo zeevalvu kwaye zaba lukhetho lokuqala kubasebenzisi abaninzi.
3. Umahluko kwixabiso
Phantsi koxinzelelo olufanayo kunye ne-caliber, ixabiso le-gate valve liphezulu kunele-butterfly valve. Nangona kunjalo, ububanzi bee-butterfly valves bunokuba bukhulu kakhulu, kwaye ixabiso le-butterfly valves ezinkulu alibizi kakhulu kune-gate valves.
