Ivalve yesangokwayeivelufa butterflyZiivalvu ezimbini ezisetyenziswa kakhulu. Bobabini bahluke kakhulu ngokwesakhiwo sabo kunye nokusebenzisa iindlela, ukulungelelaniswa neemeko zokusebenza, njl. Eli nqaku liza kunceda abasebenzisi baqonde umahluko phakathiiivalve zesangokwayeiivalve butterflynzulu ngakumbi, ukuze uncede ngcono abasebenzisi ukukhetha iivalvu.
Ngaphambi kokuchaza umahluko phakathiivalve yesangokunye ivelufa butterfly, makhe sijonge kwiinkcazelo ezimbini. Mhlawumbi ukusuka kwinkcazo, unokufumana ngokucophelela ukungafani.
Iivalvu zesango, njengoko igama lithetha, unokunqumla i-medium kumbhobho njengesango, eliluhlobo lwesivalo esiya kusisebenzisa kwimveliso kunye nobomi. Inxalenye yokuvula nokuvalwa kweivalve yesangoibizwa ngokuba yi gate plate. Ipleyiti yesango isetyenziselwa ukuphakamisa isindululo, kwaye isalathiso saso sokuhamba sijonge kwicala lokuhamba kombindi kumbhobho wolwelo. Iivalve yesangoluhlobo lwevalve ye-truncation, enokuthi ivulwe ngokupheleleyo okanye ivalwe kuphela, kwaye izinga lokuhamba alikwazi ukulungiswa.
Ivalve yebhabhathane, eyaziwa ngokuba yi-flip valve.Inxalenye yokuvula kunye nokuvala i-disc-shaped butterfly plate, egxininiswe kwisiqu kwaye ijikeleze i-stem shaft ukuvula nokuvala. Isalathiso sentshukumo yeivelufa butterflyijikeleziswa apho ikhoyo kwaye ithatha kuphela 90° ukujikelezisa ukusuka ekuvuleni ngokupheleleyo ukuya ekuvaleni ngokupheleleyo. Ukongeza, ipleyiti yebhabhathane yevalve yebhabhathane ngokwayo ayinakho ukuzivala ngokwayo. Isinciphisi somoya kufuneka sifakelwe kwisiqu. Ngayo, ivalve yebhabhathane inamandla okuzivalela, kwaye kwangaxeshanye, inokuphucula ukusebenza kwevalve yebhabhathane.
Emva kokuqonda inkcazo yeivalve yesangokunye ivelufa butterfly, umahluko phakathiivalve yesangokunye nevalve butterfly yaziswa ngezantsi:
1. Umahluko kwisakhono semoto
Ngokwengcaciso yomphezulu, siyawuqonda umahluko phakathi kwesalathiso kunye nendlela yokuhamba kweivalve yesangokunye nevalve yebhabhathane. Ukongezelela, ngenxa yokuba i-valve yesango inokuguqulwa ngokupheleleyo kwaye ivalwe, ukuchasana nokuhamba kwe-valve yesango kuncinci xa ivuliwe ngokupheleleyo; ngelixa iivelufa butterflyivuleke ngokupheleleyo, kunye nobunzima beivelufa butterflyinokumelana ne-circulation medium. Ukongeza, ukuphakama kokuvula kweivalve yesangoiphezulu kakhulu, ngoko ke isantya sokuvula kunye nokuvala sicotha; ngelixa iivelufa butterflyidinga kuphela ukujikeleza i-90 ° ukufezekisa ukuvula nokuvala, ngoko ke ukuvula kunye nokuvala ngokukhawuleza.
2. Umahluko kwiindima kunye nokusetyenziswa
Ukusebenza kokutywinwa kwevalve yesango kulungile, ngoko ke isetyenziswa kakhulu kwimibhobho efuna ukutywinwa okungqongqo kwaye ayifuni ukutshintshwa ngokuphindaphindiweyo ukunqumla imidiya yokujikeleza. Ivalve yesango ayinakusetyenziswa ukulawula ukuhamba. Ukongezelela, ngenxa yokuba isantya sokuvula kunye nokuvala i-valve yesango sihamba ngokukhawuleza, asifanelekanga ukuba imibhobho inqunyulwe ngokukhawuleza. Ivalve yebhabhathane isetyenziswa ngokubanzi. I-valve ye-butterfly ayinakunqunyulwa kuphela, kodwa inomsebenzi wokulungelelanisa ukuhamba. Ukongezelela, i-valve ye-butterfly ivula kwaye ivale ngokukhawuleza, kwaye ingaphinda ivule kwaye ivale rhoqo, ngokukodwa ifaneleka ukusetyenziswa kwiimeko apho ukuvulwa ngokukhawuleza okanye ukusika kuyadingeka.
Ubume kunye nobunzima bevalve yebhabhathane buncinci kunevalve yesango, ngoko ke kwezinye iindawo ezinendawo enyiniweyo yokufakela, kuyacetyiswa ukuba kusetyenziswe isivalo sebhabhathane esigcina isithuba esingaphezulu. Iivalve zebhabhathane zezona zisetyenziswa kakhulu kwiivalvu zodidi olukhulu, kwaye iivalve zebhabhathane nazo ziyacetyiswa kwimibhobho ephakathi equlathe ubumdaka kunye namasuntswana amancinci.
Ekukhethweni kweevalve kwiimeko 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 valve yebhabhathane. Nangona kunjalo, i-caliber yevalve yebhabhathane ingaba nkulu kakhulu, kunye nexabiso le-calibre enkuluivelufa butterflyAkukho xabiso liphantsi kunevalve yesango.
