Iivalve zesango kunye neevalve zebhabhathane zizivalo ezimbini ezixhaphake kakhulu.Bahluke kakhulu ngokwezakhiwo zabo, iindlela zokusetyenziswa, kunye nokulungelelaniswa kweemeko zokusebenza.Eli nqaku liza kunceda abasebenzisi baqonde ngcono umahluko phakathi kweevalve zesango kunye ne-butterfly valves.Uncedo olungcono abasebenzisi ukwenza ukhetho lwevalvu.
Ngaphambi kokuba uchaze umahluko phakathi kwevalve yesango kunye nevalve yebhabhathane, makhe sijonge kwiinkcazo ezihambelanayo zezi zimbini.Mhlawumbi ungafumana umahluko phakathi kwezi zibini ngononophelo ukusuka kwinkcazo.
Ivalve yesango, njengoko negama libonisa, inokuwusika umbhobho ophakathi njengesango, kwaye luhlobo lwesivalo esisetyenziswa sonke kwimveliso kunye nobomi.Indawo yokuvula kunye neyokuvala yevalve yesango ibizwa ngokuba yisango, kwaye isango lihamba linyuka liphantsi, kwaye isalathiso salo sokuhamba sixhomekeke kwindlela ehamba ngayo ye-medium kumbhobho wolwelo;i-valve yesango yi-valve yokusika, enokuvulwa ngokupheleleyo okanye ivalwe ngokupheleleyo, kwaye ukuhamba akukwazi ukulungiswa.
Ivalve yebhabhathane, ekwabizwa ngokuba yi-flap valve.Indawo yayo yokuvula neyokuvala yipleyiti yebhabhathane emile okwediski, ethi imiliselwe kwisiqu sevalve kwaye ijikeleze iaxis yevalve yevalve ukuqonda ukuvuleka nokuvala.Isalathiso sokuhamba kwevalve yebhabhathane kukujikeleza kwi-situ, kwaye kufuneka kuphela ukujikeleza i-90 ° ukusuka ekuvulekeni ngokupheleleyo ukuya kukuvalwa ngokupheleleyo.Ukongeza, ipleyiti yebhabhathane yevalve yebhabhathane ngokwayo ayinakho ukuzivalela, kwaye i-worm gear reducer kufuneka ifakwe kwi-valve stem.Ngayo, i-butterfly plate inekhono lokuzivalela, kwaye inokuphucula ukusebenza kwevalve yebhabhathane.
Ukwazi inkcazo yevalve yesango kunye nevalve yebhabhathane, umahluko phakathi kwevalve yesango kunye nevalve yebhabhathane yaziswa ngezantsi:
1. Umahluko kubuchule bezemidlalo
Kule nkcazo ingentla, siyawuqonda umahluko kwindlela eya kwicala kunye nendlela yokuhamba kweevalve zesango kunye ne-butterfly valves.Ukongezelela, iivalve zesango zinokuvuleka ngokupheleleyo kwaye zivaliwe ngokupheleleyo, ngoko xa zivuleke ngokupheleleyo, iivalve zesango zinokuchasana nokuhamba okuncinci;Iivalve zebhabhathane Kwimeko evuleke ngokupheleleyo, ubukhulu bevalve yebhabhathane budala ukuxhathisa kwindawo ehambayo.Ukongezelela, i-valve yesango inobude obuphezulu bokuvula, ngoko ke ukuvulwa nokuvala isivinini kucotha;ngelixa ivalve yebhabhathane inokuvulwa kwaye ivalwe ngokujikeleza kuphela i-90 °, ngoko ke isantya sokuvula nokuvala sikhawuleza.
2. Umahluko phakathi komsebenzi kunye nokusetyenziswa
Ivalve yesango inomsebenzi omhle wokutywina, ngoko ke isetyenziswa kakhulu kwimibhobho efuna ukutywinwa okungqongqo kwaye akufuneki ukuba itshintshelwe ngokuphindaphindiweyo ukunqumla okuphakathi.Ivalve yesango ayinakusetyenziswa ukulungelelanisa izinga lokuhamba.Ukongezelela, ngenxa yokuba isantya sokuvula nokuvalwa kwevalve yesango sicotha, asifanelekanga kumbhobho omele unqunyulwe ngokukhawuleza.Ukusetyenziswa kweevalve zebhabhathane kubanzi ngakumbi.Iivalve zeButterfly azinakusetyenziselwa ukunqunyulwa kuphela, kodwa zinomsebenzi wokulungelelanisa ubungakanani bokuhamba.Ukongezelela, i-valve butterfly ivula kwaye ivale ngokukhawuleza, kwaye ingavulwa kwaye ivalwe rhoqo, ngokukodwa ifanelekile ukusetyenziswa kwiimeko ezifuna ukuvulwa ngokukhawuleza okanye ukuvala.
Ubungakanani bevalve yebhabhathane buncinci kunevalve yesango, kwaye ubunzima bayo bubuye bube khaphukhaphu kunobo bevalve yesango.Ke ngoko, kwezinye iimeko ezinendawo enyiniweyo yofakelo, kuyacetyiswa ukuba usebenzise ivalve yebhabhathane egcina isithuba esonga kakhulu.Phakathi kwee-valve ezinobubanzi obukhulu, i-valve ye-butterfly isetyenziswa kakhulu, kwaye iyacetyiswa ukuba isebenzise i-valve ye-butterfly kumbhobho ophakathi oqukethe amaqhekeza amancinci okungcola.
Ekukhethweni kweevalve kwiimeko ezininzi zokusebenza, iivalve zebhabhathane ziye zatshintsha ngokuthe ngcembe ezinye iintlobo zeevalvu kwaye zibe lukhetho lokuqala lwabasebenzisi abaninzi.
3. Umahluko kwixabiso
Ngaphantsi koxinzelelo olufanayo kunye nomgangatho ofanayo, ixabiso levalve yesango liphezulu kunelo valve yebhabhathane.Nangona kunjalo, umgangatho wevalve yebhabhathane unokwenziwa ube mkhulu kakhulu, kwaye ixabiso levalve yebhabhathane elikhulu alikho xabiso liphantsi kunelo levalve yesango.
