Uma kuziwa emhlabeni wama-valve ovemvane bezentengiselwano, akuwona wonke amadivaysi adalwe alinganayo. Kunomehluko omningi phakathi kwezinqubo zokukhiqiza kanye namadivayisi ngokwawo ashintsha ukucaciswa namakhono kakhulu. Ukuze ulungiselele kahle ukukhetha, umthengi kufanele afunde ubuchwepheshe kanye nomehluko ezinhlobonhlobo ezihlukahlukene ukuze akhethe idivayisi yakhe kahle.
Ayini Ama-Butterfly Valves?
I-valve uvemvane ucezu oluthile lwehadiwe eyakhelwe ukulawula ukugeleza kwanoma yiluphi uhlobo lwento ewuketshezi noma ewuketshezi oluwuketshezi oludlula ochungechungeni lwamapayipi. Lawa mapayipi angakwazi ukuthutha izinhlobonhlobo zezinto ezifana namanzi, uwoyela, uphethiloli, imfucuza, nanoma yiluphi olunye uhlobo lwegesi, uketshezi noma uketshezi oluwuketshezi.
Lokhu kulungiswa kokugeleza kwenziwa ngokusebenzisa i-disc eyindilinga ejikelezayo ukuze inikeze imvume noma ukuvala indawo yepayipi yangaphakathi. Lapho i-disc iphonswa endaweni e-perpendicular eya endaweni yangaphakathi yepayipi, ivala i-passage futhi imise ukugeleza ngokuphelele. Uma ijikeleziswa ukuze ibekwe ngokuhambisana nepayipi, ukuvinjelwa kuyasuswa futhi ukugeleza okugcwele kuphinde kuvunyelwe. I-valve ingabuye ibekwe emaphoyinti phakathi, inwebe noma inciphise iphasi ngokunyuka njengoba kucaciswe idivayisi yokulawula ukugeleza.
Ukwakhiwa kwama-Butterfly Valves
Impahla yokwakha ye-valve inquma amandla ayo nokuphila isikhathi eside. Amavalvu aklanyelwe ukugeleza okukhulu, ingcindezi ephezulu, kanye nokusetshenziswa isikhathi eside, ikakhulukazi ezindaweni ezikude, ngokuvamile akhiwa ngohlaka noma insimbi eqinisiwe. Ezinye izinguqulo eziklanyelwe umsebenzi olula noma ukusetshenziswa kwesikhathi esifushane zenziwe ngezinto ezifana ne-alloy ekhanyayo, i-aluminium, noma ipulasitiki ye-PVC. Amavalvu ekhwalithi ephezulu akhiwe ukuze amelane nobunzima bokuphatha ukucindezela okukhulu kakhulu, aphathe ukugeleza kwezinto ezibalulekile, futhi abe nokuqina okudingekayo ukuze asetshenziswe isikhathi eside. Kumadivayisi asezindaweni okunzima ukufinyelela kuzo noma angcwatshwe phansi phansi, kudingeka ivalvu yesitayela ehlala njalo. Izindleko zokufinyelela umshini onjalo wokushintshwa zivame ukuba yisayensi yezinkanyezi, ngakho-ke ukutshala imali ku-valve yekhwalithi ephezulu kakhulu kusukela ekuqaleni kuyisinqumo esihlakaniphile.
Izicelo Ezithize
Ukukhetha i-valve ngokohlelo oluthile kubalulekile. Ezinye azisindi futhi zenzelwe imigqa yamanzi emincane noma isilawuli selayini kaphethiloli. Ama-Aquarium, amachibi, nezinhlelo zokufafaza ziyizibonelo ezinhle zomsebenzi wokukhanya, ukusetshenziswa okungabalulekile kwamavalvu ovemvane.
Izicelo ezidinga kakhulu njengamapayipi egesi, izinhlelo zokuthutha uwoyela noma amasistimu okushintsha amanzi edolobha anengcindezi ephezulu zidinga amavalvu ekhwalithi ephezulu, anokwethenjelwa anomjikelezo wokuphila owandisiwe. Lawa madivayisi anomsebenzi osindayo ahlolelwa ukusebenza nokuthembeka kwafekthri, ukuze ahlangabezane futhi adlule izimfuno zemisebenzi ebalulekile yenjongo.
Ukucaciswa komkhiqizi kungaveza imininingwane yamantongomane namabhawodi wamakhono evalvu ngayinye. Ukukhetha i-valve efanele yomsebenzi kubalulekile ekusetshenzisweni kwesikhathi eside namathuba ancishisiwe okuhluleka kwemishini.
Izinga Lokunemba
Esinye isici esibalulekile ekukhetheni i-valve yohlelo lokusebenza izinga lokunemba eliklanyelwe kudivayisi. Ivalvu ngayinye inemininingwane echaza inani lokuvuza, uma likhona, endaweni yokuvala, ukuthi iphasishi libanzi kangakanani, umthamo owuketshezi ongadlula lapho usuvulwe ngokugcwele, nokuthi ivalvu ithembeke kangakanani isikhathi eside. Imininingwane iphinde ibe nemininingwane ngesivinini sokusebenza kwevalvu, ilungele izimo lapho ukusebenza okunesikhathi kuyisidingo.
Izinketho zokulawula
Isici esilandelayo esibalulekile ekukhetheni i-valve yohlelo olunikeziwe yindlela yokulawula. Amanye ama-valve ahlanganisa i-lever noma isibambo, esiklanyelwe ukuguqulwa ngesandla ukusuka ekuvulekeni kuya kokuvaliwe. Isibambo sivamise ukuba nekota yokujika kohambo ukusuka ekugcineni ukuya ekugcineni, ukuze ushintshe ngokushesha futhi kalula isimo sevalvu. Eminye iklanyelwe ukuthi i-othomathikhi ngokusebenzisa idivayisi yokushintsha engumshini njenge-solenoid noma okunye ukuhamba kwemishini ngokomzimba.
Ama-valve asethuthuke kakhulu afaka isistimu yokulawula yemoto kagesi enamandla onke. Le moto izungeza i-shaft ye-valve ngokuqondile noma inyakazise i-lever ngokusebenzisa ingalo ye-actuator. Okunye kunikeza ukulawula okugcwele kusuka endaweni ekude futhi kungasetshenziswa ukulungisa ukulawula ukugeleza okunembile uma kudingeka.
Amandla e-valve
Isici sokugcina ekukhetheni i-valve amandla edivayisi. Lokhu kuhlanganisa imininingwane yokugeleza yokuthi kungakanani okudlula ku-valve ngesikhathi esinikeziwe, nokuthi ingakanani ingcindezi yangaphakathi i-valve engakwazi ukuyibekezelela ngokuphepha. Kumishini yokucindezela okukhulu, okugeleza okukhulu kuyadingeka ivalvu enkulu, yekhwalithi ephezulu, enosayizi ofanele wokufanisa isistimu yamapayipi anamathiselwe. Qiniseka ukuthi ubheka imininingwane ngokumelene nezidingo zakho ezithile ukuze uqinisekise ukuthi i-valve inekhono elanele lohlelo lokusebenza.
I-Butterfly Valves Ukusekela
Ekusetshenzisweni okuningi, into enqumayo ingase yehlele enkampanini kanye nerekhodi layo lokulandelela namakhasimende. Umnyango wokusekela onamandla nesevisi ngemva kokuthengisa kubalulekile ekusebenzeni kwebhizinisi futhi ungenza noma uphule imigomo yakho ngokutholakala kwayo. Qiniseka ukuthi ubambisana nomthombo onokwethenjelwa, onedumela elihle lapho ukhetha amavalvu ngezidingo zakho ezithile.
