Ngokufutshane, ivalve yebhabhathane yivalve ejikelezayo yekota. Njengayo nayiphi na enye ivalve, zisetyenziselwa ukuqalisa, ukumisa, kunye nokulawula ukuhamba. Olu hlobo lwevalve lukho ukususela ekuqaleni kwe-1930s kwaye lunoluhlu olubanzi lwezicelo kwi-industrial set up. Iivalvu zebhabhathane zenziwe ngezinto ezahlukeneyo kwaye igama labo livela ekusebenzeni kweediski zayo, nangona igama elichaneke ngakumbi bekuya kuba yiDisc Valve.
Umgaqo wokusebenza ubandakanya ukujikeleza i-lever yabo 0- 90 ° — oku kubonelela mhlawumbi ngokuvula ngokupheleleyo okanye ukuvala ivalve. Olunye uphawu olubalulekileyo kukuba ezi valves zinokuxhotyiswa ngendlela efana nebhokisi yegiya. Kwi-setup, ivili lesandla elivela kwiigiya lixhunyiwe kwi-stem, okwenza i-valve isebenze lula kodwa ngesantya esiphantsi kunye neevalve ezinkulu. Ngaloo nto engqondweni, makhe sijonge iindlela zokufakela iintlobo ezahlukeneyo zevalve yebhabhathane.
IValve yebhabhathane eZimeleyo (RSBFV)
Zimbini uyilo olusisiseko:
ICartridge ehleliyo isebenzisa isitulo serabha ngaphezulu kweringi egcina ibackup, idla ngokuba yiphenolic, isenza isihlalo sibe ngqongqo kakhulu. Ukufakela kufuna kuphela ukufaka umzimba wevalve phakathi kweeflanges, ukuyibeka embindini, kunye nokuqinisa iibholithi kwi-torque ekhankanyiweyo. Isitayile se-Wafer sinokuza okanye singezi nemingxunya esembindini ngelixa umzimba we-Lug uye womba kwaye wacofa imingxuma ehambelana nemingxuma yeflange kwaye igxile ngokulula.
I-Boot Seated isebenzisa isitulo esiguquguqukayo esigotywayo ngaphakathi emzimbeni kwaye sigcinwe kwindawo yeflange ngomsele, oqhele ukuba nesikwere sehobe kubuso beflange. Le valve ayinakufakwa kwindawo evaliweyo ngokupheleleyo kodwa kufuneka iqhekezwe ivuleke malunga ne-10% ngelixa ihlala ngaphakathi kwimvulophu yomzimba kwaye isilayidi ngononophelo phakathi kweeflange, ulumke ungabambeki umlebe wesihlalo kumda we-ID, ngokufanelekileyo "ukuqengqeleka". "Isitulo kwindawo yediski. Apha kwakhona, i-valve, nokuba yi-wafer okanye i-lug, kufuneka ibekwe phakathi.

Ukusebenza okuphezulu, i-Double Offset, kunye ne-Triple Offset Butterfly Valve
Olu yilo lwevalvu ludibanisa i-offset njengoko kubonisiwe ngegama labo, olwenziwe yijiyometri yoyilo lwendawo yokuhlala. Inkqubo yokuyenza ibandakanya ukwenza isihlalo sibe kwiprofayili ye-offset. Olu phawu lwenza kube lula ukubethelwa ngokungakhubekiyo kuwo wonke umjikelo. Uqhagamshelwano ludityaniswe kwindawo yokugqibela yokuvalwa kwaye lufakwe kwi-90 ° lusebenza njenge-mechanical flow stop.
Nantsi inkqubo yokuhlohla:
Coca umbhobho wazo zonke izinto ezingcolileyo.
Qinisekisa isalathiso se-fluid, i-torque njengoko ukuhamba kwi-disc kunokuvelisa i-torque ephezulu kunokungena kwicala le-shaft ye-disc.
Beka idiski kwindawo evaliweyo ngexesha lofakelo ukukhusela umonakalo wokutywinwa komphetho we-disc.
Ukuba kuyenzeka, ngawo onke amaxesha isivalo kufuneka sixhonywe ngesiqu sithe tyaba ukunqanda ubutyobo bombhobho obuqokelelwa ezantsi kunye nofakelo lobushushu obuphezulu.
Kufuneka ihlale ifakwe phakathi kweeflange njengoko kukhankanyiwe ngasentla. Oku kunceda ukuphepha umonakalo kwi-disc kunye nokuphelisa ukuphazamiseka kombhobho kunye ne-flange.
Sebenzisa ulwandiso phakathi kwevalve yebhabhathane kunye nevalve yokujonga iwafer.
Zama i-disc ngokuyisusa kwindawo evaliweyo ukuze uvule kwaye ubuye umva ukuqinisekisa ukuba ihamba ngokuguquguqukayo.
Qinisa iibholithi zeflange (ukuqinisa ngokulandelelana) ukukhusela ivalve ngokulandela iitorque ezicetyiswa ngabavelisi.
EZI VAVAVU ZIFUNA IIGASTHI ZESIFLANGE KUMAQALA OMABILI OBUSO OBHULUMENTE, AKHETHELWE INKONZO EJOLISWE KUYO.
