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, inokunqumla okuphakathi kumbhobho 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 kunye neyokuvala yipleyiti yebhabhathane emile okwediski, egxininiswe kwisiqu sevalve kwaye ijikeleze isiqu sevalve ukufezekisa ukuvula nokuvalwa.Isalathiso sentshukumo yevalve yebhabhathane kukujikeleza endaweni, kwaye idinga kuphela ukujikeleza i-90 ° ukusuka ekuvuleni 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.
ukuba siyaziqonda iinkcazo zeevalvu zesango kunye neevalve zebhabhathane,vumela's yazisa umahluko phakathi kweevalvu zesango kunye neevalvu zebhabhathane:
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 ke xa zivuleke ngokupheleleyo, ukuchasana kokuhamba kweevalve zesango kuncinci;Iivalve zebhabhathane Kwimeko evuleke ngokupheleleyo, ubukhulu bevalve yebhabhathane budala ukuxhathisa kumbindi ohambayo.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 kwimisebenzi kunye nokusetyenziswa
Iivalve zesango zisebenza kakuhle, ngoko ke zihlala zisetyenziswa kwimibhobho efuna ukutywinwa okungqongqo kwaye akufuneki ukuba ivulwe kwaye ivalwe rhoqo ukuze kunqunyulwe isithuba esijikelezayo.Ivalve yesango ayinakusetyenziswa ukulawula ukuhamba.Ukongezelela, ngenxa yokuba isantya sokuvula kunye nokuvala i-valve yesango ihamba kancinci, ayifanelekanga kwiipayipi ezifuna ukuvala ngokukhawuleza.Ukusetyenziswa kweevalve zebhabhathane kubanzi ngakumbi.Iivalve ze-Butterfly azikwazi ukusetyenziselwa ukusika kuphela, kodwa zinomsebenzi wokulungelelanisa izinga lokuhamba.Ukongeza, ivalve yebhabhathane ivula kwaye ivale ngokukhawuleza kwaye inokuvulwa kwaye ivalwe rhoqo.Kufanelekile ngokukodwa ukusetyenziswa kwiimeko ezifuna ukuvulwa ngokukhawuleza okanye ukuvala.
Iivalvu zebhabhathane zincinci ngobungakanani kwaye zikhaphukhaphu ngobunzima kuneevalvu zesango, ngoko ke kwezinye iimeko ezinendawo enyiniweyo yokufakela, kuyacetyiswa ukuba kusetyenziswe ivalve yebhabhathane egcina isithuba esingaphezulu.Phakathi kweevalve ezinobubanzi obukhulu, iivalve zebhabhathane zezona zisetyenziswa ngokuqhelekileyo.Iivalve zebhabhathane nazo ziyacetyiswa ekuthuthweni kwemibhobho yemidiya equlethe ubumdaka obuncinci.
Ngokumalunga nokukhethwa kwevalve phantsi kweemeko ezininzi zokusebenza, iivalve zebhabhathane ziye zatshintsha ngokuthe ngcembe ezinye iintlobo zeevalvu kwaye zibe lukhetho lokuqala kubasebenzisi abaninzi.
3. Umahluko kwixabiso
Ngaphantsi koxinzelelo olufanayo kunye nomgangatho, ixabiso levalve yesango liphezulu kunelo levalve yebhabhathane.Nangona kunjalo, ububanzi beevalvu zebhabhathane bunokuba bukhulu kakhulu, kwaye ixabiso leevalve zebhabhathane ezinobubanzi obukhulu alibizi kuneevalvu zesango.
