I-globe valve isebenza, zonke izinhlobo zezingxenye ze-valve kufanele ziphelele futhi ziphelele.Amabhawudi ku-flange nakubakaki abalulekile.Intambo kufanele iphelele futhi akukho ukuxegiswa okuvunyelwe.I-Fastening nut ku-handwheel, uma itholakala ikhululekile kufanele iqiniswe ngesikhathi, ukuze ungagqoki uxhumano noma ulahlekelwe isondo lesandla ne-nameplate.Uma isondo lesandla levalvu yeglowubu lilahlekile, isipanela esilungisekayo asivunyelwe ukuthi sisetshenziswe esikhundleni futhi kufanele sifakwe ngesikhathi.Indlala yokupakisha ayivunyelwe ukutsheka noma ingabi namvume yokulayisha kuqala.Isembozo sokuzivikela kufanele sifakwe esiqwini se-valve yembulunga endaweni engcoliswa kalula yimvula, iqhwa, uthuli, isihlabathi nokunye ukungcola.Igeji kuvalvu yembulunga kufanele iphelele, inembile futhi icace.Isivalo, ikepisi kanye nezinsiza zomoya zevalvu yomhlaba kufanele ziphelele futhi zingaguquki.Ungangqongqozi, ume noma usekele izinto ezinzima kuvalvu yembulunga esebenzayo;Ama-valve angewona awensimbi kanye ne-cast iron valve, ikakhulukazi, ngaphezulu azomisa i-valve emsebenzini wokunakekela ekukhiqizeni i-welding ngaphambi nangemva kokugcinwa kochwepheshe be-valve, ngoba i-valve enkonzweni yokukhiqiza idlala indima ebalulekile, ukugcinwa okuhlelekile nokuphumelelayo. izovikela i-valve efanele, i-valve ukuze isebenze kahle, futhi yelule impilo yesevisi ye-valve.Ukugcinwa kwe-valve kungase kubonakale kulula, kodwa akunjalo.Kuvame ukushaywa indiva izici zomsebenzi.
Okokuqala, lapho i-valve yembulunga igcoba, inkinga yokujova amafutha ngokuvamile ayinakwa.Ngemuva kokugcwalisa amafutha, opharetha ukhetha i-valve nemodi yokuxhuma amafutha futhi enze umsebenzi wokugcwalisa amafutha.Kunezimo ezimbili: ngakolunye uhlangothi, inani lomjovo wamafutha lincane, futhi indawo yokuvala uphawu igqokwa ngokushesha ngenxa yokuntuleka kokuthambisa.Ngakolunye uhlangothi, umjovo ngokweqile wamafutha, okuholela ekumosheni.Asikho isibalo esinembile samandla okuvala ama-valve embulunga ahlukene ngokohlobo nesigaba samavalvu.Umthamo wokuvala ungabalwa ngosayizi kanye nesigaba se-valve yokusika, bese kufakwa inani elifanele lamafutha.
Okwesibili, inkinga yokucindezela ngokuvamile ayinakwa lapho i-valve yembulunga igcoba.Ngesikhathi sokusebenza komjovo wamafutha, ukucindezela komjovo wamafutha kushintsha njalo ngeziqongo nezigodi.Ingcindezi iphansi kakhulu, uphawu luyavuza noma lwehluleke, ukucindezela kuphezulu kakhulu, umlomo wamafutha uvalekile, ugrisi osesigxivini uyaqina noma iringi yokuvala ivalwe ngebhola levalvu kanye nepuleti levalvu.Imvamisa, lapho umfutho wamafutha uphansi kakhulu, igrisi ejovwe igelezela ngaphansi kwegumbi le-valve, elivame ukwenzeka kumavalvu amancane okunuka.Futhi ukucindezela kwamafutha kuphezulu kakhulu, ngakolunye uhlangothi, hlola i-nozzle yamafutha, bese uyishintsha uma imbobo yamafutha ivinjiwe;Ngakolunye uhlangothi ukuqina kwe-lipid, ukusebenzisa uketshezi lokuhlanza, ukuthambisa ngokuphindaphindiwe ukwehluleka kwegrisi yokuvala, bese ujova ukushintshwa kwamafutha amasha.Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokubeka uphawu nazo zithinta ukucindezela kwamafutha.Amafomu ahlukene okuvala anomfutho ohlukile wamafutha.Ngokuvamile, umfutho wamafutha we-hard seal uphakeme kunalowo we-soft seal.Ukugcinwa kokufundwa kwebhola ngokuvamile kusendaweni evulekile, izimo ezikhethekile zikhetha ukuvala ukulungiswa.Amanye ama-valve awakwazi ukuvula indawo yonke.I-valve yesango kufanele ivalwe ngesikhathi sokulungiswa ukuze kuqinisekiswe ukuthi amafutha agcwele i-groove yokuvala eduze nendandatho yokuvala.Uma ivuliwe, igrisi yokuvala izowela ngqo kumzila wokugeleza noma ekamelweni le-valve, okubangela ukungcola.

Ngemuva kokufakwa, i-valve yembulunga kufanele ihlolwe njalo.Izinto zokuhlola eziyinhloko yilezi:
(1) ukugqokwa kwendawo yokuvala yevalvu yembulunga.
(2) Ukugqokwa kwentambo ye-trapezoidal yesiqu ne-stem nut.
(3) Ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile.Uma yonakele, kufanele ishintshwe ngesikhathi.
(4) ngemva kokulungiswa nokuhlanganiswa kwevalvu yembulunga, ukuhlolwa kokusebenza kokuvala kufanele kwenziwe.

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
