Uma kukhulunywa ngomhlaba wama-valve e-butterfly ezentengiselwano, akuwona wonke amadivayisi adalwe ngokulinganayo. Kunezinhlobo eziningi zomehluko phakathi kwezinqubo zokukhiqiza namadivayisi ngokwawo ezishintsha kakhulu imininingwane namakhono. Ukuze alungiselele kahle ukukhetha, umthengi kumele afunde ubuchwepheshe kanye nomehluko kuhlobo ngalunye ukuze akhethe idivayisi yakhe kahle.
1.Ukwakhiwa kwama-Butterfly Valve
Izinto zokwakha zevalvu zinquma amakhono ayo kanye nobude bayo. Amavalvu aklanyelwe ukugeleza okunzima, umfutho ophezulu, kanye nokusetshenziswa isikhathi eside, ikakhulukazi ezindaweni ezikude, ngokuvamile akhiwa ngensimbi eqinisiwe noma eqinisiwe. Ezinye izinhlobo ezenzelwe umsebenzi olula noma ukusetshenziswa kwesikhathi esifushane zenziwe ngezinto ezifana ne-alloy elula, i-aluminium, noma ipulasitiki ye-PVC. Amavalvu asezingeni eliphezulu aklanywe ukuze amelane nobunzima bokuphatha umfutho ophezulu kakhulu, athwale ukugeleza okukhulu kwezinto, futhi abe nokuqina okudingekayo ukuze asetshenziswe isikhathi eside. Kumadivayisi asezindaweni okunzima ukufinyelela kuzo noma agqitshwe phansi komhlaba, kudingeka ivalvu yesitayela esihlala njalo. Izindleko zokufinyelela idivayisi enjalo ukuze ishintshwe zivame ukuba zinkulu kakhulu, ngakho-ke ukutshala imali kuvalvu yekhwalithi ephezulu kusukela ekuqaleni kuyisinqumo esihlakaniphile.
2.Izicelo Ezithile
Ukukhetha ivalvu ngokwesicelo esithile kubalulekile. Amanye alula futhi aklanyelwe imisele emincane yamanzi noma ukulawula imisele kaphethiloli. Ama-aquarium, amachibi okubhukuda, kanye nezinhlelo zokufafaza ziyizibonelo ezinhle zokusetshenziswa okulula, okungabalulekile kwamavalvu ezimvemvane.
Izinhlelo zokusebenza ezidinga kakhulu njengemipayipi yegesi, izinhlelo zokuthutha uwoyela noma izinhlelo zokushintsha amanzi edolobheni ezinomfutho ophezulu zidinga ama-valve asezingeni eliphezulu, athembekile anomjikelezo wokuphila owengeziwe. Lawa madivayisi asebenza kanzima ahlolwa embonini ukuze asebenze kahle futhi athembeke, ukuze ahlangabezane futhi adlule izidingo zemisebenzi ebalulekile.
Imininingwane yomkhiqizi ingaveza imininingwane yamakhono evalvu ngayinye. Ukukhetha ivalvu efanele yomsebenzi kubalulekile ekusetshenzisweni kwesikhathi eside ngamathuba ancishisiwe okwehluleka kwemishini.
3.Izinga Lokunemba
Esinye isici esibalulekile ekukhetheni ivalvu yohlelo lokusebenza yizinga lokunemba elifakwe kudivayisi. Ivalvu ngayinye inemininingwane echaza inani lokuvuza, uma likhona, endaweni yokuvala, ukuthi indlela ibanzi kangakanani, umthamo woketshezi ongadlula lapho ivuliwe ngokugcwele, nokuthi ivalvu ithembeke kangakanani isikhathi eside. Imininingwane iphinde ichaze isivinini sokusebenza kwevalvu, ilungele izimo lapho ukusebenza kwesikhathi kuyisidingo.
4.Izinketho Zokulawula
Isici esilandelayo esibalulekile ekukhetheni ivalvu yohlelo oluthile yindlela yokulawula. Amanye amavalvu afaka i-lever noma isibambo, esenzelwe ukushintshwa ngesandla kusuka ekuvulekeni kuya ekuvaliwe. Isibambo ngokuvamile sinokujika kwekota kokuhamba kusuka ekugcineni kuya ekugcineni, ukuze kushintshwe isimo sevalvu ngokushesha nangokulula. Amanye aklanyelwe ukuba azenzekele ngokusebenzisa idivayisi yokushintsha ngomshini njenge-solenoid noma olunye uhambo olungokoqobo ngomshini.
Amavalvu athuthuke kakhulu afaka uhlelo lokulawula lwemoto kagesi olusebenza ngokugcwele. Le moto ijikeleza ngqo umgodi wevalvu noma inyakazise i-lever ngokusebenzisa ingalo ye-actuator. Noma iyiphi yazo inikeza ukulawula okugcwele kusuka endaweni ekude futhi ingasetshenziswa ukulungisa ukulawula ukugeleza okunembile uma kudingeka.
5.Umthamo weValve
Isici sokugcina ekukhetheni ivalvu umthamo wedivayisi. Lokhu kufaka phakathi imininingwane yokugeleza kokuthi kungakanani okudluliswayo kuvalvu ngesikhathi esithile, nokuthi ivalvu ingamelana nokucindezeleka kwangaphakathi okungakanani ngokuphephile. Kumadivayisi okugeleza anamandla aphezulu, kudingeka ivalvu enkulu, esezingeni eliphezulu, enosayizi ofanele ohambisana nohlelo lwepayipi olunamathiselwe. Qiniseka ukuthi uhlola imininingwane ngokuhambisana nezidingo zakho ezithile ukuqinisekisa ukuthi ivalvu inamandla anele okusetshenziswa.
