Ngamafuphi, i-valve uvemvane iyi-valve ejikelezayo eyikota. Njenganoma iyiphi enye i-valve, asetshenziselwa ukuqala, ukumisa, nokulawula ukugeleza. Lolu hlobo lwe-valve lukhona kusukela ekuqaleni kwawo-1930 futhi lunohlu olubanzi lwezicelo ekusungulweni kwezimboni. Ama-valve ovemvane enziwe ngezinto ezihlukahlukene futhi igama lawo livela ekusebenzeni kwamadiski alo, nakuba igama elinembe kakhulu bekungaba yi-Disc Valve.
Isimiso sokusebenza sihlanganisa ukuzungezisa i-lever yabo 0- 90 ° - lokhu kunikeza ukuvuleka okuphelele noma ukuvalwa kwevalvu. Okunye okubalulekile ukuthi la ma-valve akwazi ukuhlonyiswa ngomshini ofana no-gearbox. Ekusetheni, isondo lesandla elisuka kumagiya lixhunywe esiqwini, okwenza i-valve isebenze kalula kodwa ngesivinini esiphansi kanye nama-valve amakhulu. Unalokho engqondweni, ake sibheke izindlela zokufaka izinhlobo ezahlukene zamavalve ovemvane.
I-Resilient Seated Butterfly Valve(RSBFV)
Kunemiklamo emibili eyisisekelo:
I-Cartridge Seated isebenzisa isihlalo senjoloba phezu kwendandatho eyisipele eqinile, ngokuvamile i-phenolic, okwenza isihlalo siqine kakhulu. Ukufakwa kudinga kuphela ukufaka umzimba we-valve phakathi kwama-flange, ukuwumisa phakathi nendawo, futhi uqinise amabhawodi ku-torque ecacisiwe. Isitayela se-Wafer singase size noma singezi nezimbobo ezimaphakathi ngenkathi umzimba we-Lug ubhoboze futhi wathinta izimbobo ezifana nezimbobo ze-flange futhi zigxile kalula.
I-Boot Seated isebenzisa isihlalo esigobekayo esigoqeka ngaphakathi emzimbeni futhi sibanjwe endaweni ehlangothini lwe-flange nge-groove, ngokuvamile isikwele se-dovetail ebusweni be-flange. Le valve ayikwazi ukufakwa endaweni evalwe ngokugcwele kodwa kufanele iqhekeke ivuleke cishe u-10% ngenkathi ihlala ngaphakathi kwemvilophu yomzimba futhi islayidi ngokucophelela phakathi kwama-flange, uqaphele ukuthi ungalubambi udebe lwesihlalo onqenqemeni lwe-ID ye-flange, "igingqika" ngokuphumelelayo. "isihlalo endaweni yediski. Lapha futhi, i-valve, noma i-wafer noma i-lug, idinga ukugxila.
* AKUKHO IVALI OKUDINGA AMAGASEKI E-FLANGE
* UKUSETSHENZISWA KWAMAGASEKI E-FLANGE KUPHUMA ISIQINISEKISO SOMPHAKATHI WOKUQALA.
* ISIHLALO SIYIGASKET!
Ukusebenza Okuphezulu, I-Double Offset, ne-Triple Offset Butterfly Valve
Le miklamo ye-valve ihlanganisa i-offset njengoba kuboniswe igama layo, eyenziwe umklamo wejometri wendawo yokuhlala. Inqubo yokuyenza ibandakanya ukulungisa isihlalo sibe yiphrofayili ye-offset. Lesi sici sisiza ukungqubuzana okungenantambo kuwo wonke umjikelezo. Othintwayo uhlanganiswa endaweni yokugcina yokuvalwa futhi afakwe ku-90° asebenze njengesitobhi sokugeleza komshini.
Nansi inqubo yokufaka:
Hlanza ipayipi lakho konke ukungcola.
Nquma isiqondiso soketshezi, i-torque njengoba ukugeleza ku-disc kungase kukhiqize i-torque ephakeme kunokugeleza kuhlangothi lwe-shaft lwe-disc.
Beka idiski endaweni evaliwe ngesikhathi sokufakwa ukuze uvimbele ukulimala konqenqema lokuvala idiski.
Uma kungenzeka, ngaso sonke isikhathi i-valve kufanele ifakwe nesiqu sivundlile ukugwema ukuqoqwa kwemfucumfucu yamapayipi ngaphansi kanye nokufakwa kwezinga lokushisa eliphezulu.
Kufanele ihlale ifakwe phakathi kwama-flange njengoba kushiwo ngenhla. Lokhu kusiza ukugwema ukulimala kwidiski futhi kuqede ukuphazamiseka kwepayipi kanye ne-flange.
Sebenzisa isandiso phakathi kwevalve uvemvane nevalve yokuhlola i-wafer.
Zama idiski ngokuyisusa endaweni evaliwe ukuze uvule futhi uyibuyisele emuva ukuze uqinisekise ukuthi ihamba kalula.
Qinisa amabhawodi e-flange (ukuqinisa ngokulandelana) ukuze uvikele i-valve ngokulandela ama-torque anconywa abakhiqizi.
LAWA AMAVAVAVU ADINGA AMAGASEKI E-FLANGE EZINHLAMENI ZOMBILI ZOBUSO VEVA, ABAKHETHELWE INKONZO EHLOSIWE.
* Ukuthobela konke ukuphepha nokusebenza okuhle kwemboni.
