Ama-valves we-tlob Njalo i-valve yehlukile ngokubukeka, ngesakhiwo kanye nokusetshenziswa okusebenzayo. Kodwa-ke, i-valve ye-Globe Valve kanye nesango le-valu linokufana okuthile okufanayo, futhi ngasikhathi sinye linomsebenzi wokuxinana epayipini, ngakho-ke kuzoba nabangane abaningi abangenayo oxhumana nabo ababili. Eqinisweni, uma ubhekisisa, umehluko phakathi kwe-valve ye-hlaba lomhlaba kanye ne-values valve kusekukhulu impela.
- Ukwakheka
Endabeni yesikhala sokufaka esilinganiselwe, kuyadingeka ukunaka ukukhethwa kwe:
I-valulve valve ingavalwa ngokuqinile nendawo yokubopha uphawu ngokuncika ekucindezelweni okuphakathi, ukuze kufinyelelwe umphumela wokuvuza. Lapho uvula futhi uvala, i-spool ye-valve kanye nesihlalo se-valve seaning sihlala sihlangana komunye nomunye, futhi indawo ye-BASTVE kulula ukuyigqoka, futhi lapho i-BASTVE BASTVE KUFANELE ukuvalwa, futhi lapho i-Facling Valve phakathi kwepayipi inkulu kakhulu, yenza indawo yokubopha igqoke kakhulu.
Ukwakheka kwe-varve valve kuzoba yinkimbinkimbi ukwedlula i-valve yembulunga yonke, kusuka endaweni yokubuka, esimweni se-caliber efanayo, isango le-calve liphakeme kune-valve ye-global, futhi i-valve ye-hlaba inde kune-valve valve. Ngaphezu kwalokho, i-valve valve ihlukaniswe ngenduku ekhanyayo nenduku emnyama. IValve Valve ayikho.
- Umsebenzi
Lapho i-valve ye-hlaba ivaliwe futhi ivaliwe, kuwuhlobo lwesiqu esikhuphukayo, okusho ukuthi, isondo lesandla liyajikelezwa, futhi isondo lesandla lizoshintshana, futhi isondo lesandla lizoshintshana ngokujikeleza nokuphakamisa ukunyakaza kanye nesiqu se-valve. I-valve valve ukuguqula i-handwheel, ukuze isiqu senza ukunyakaza okuphakamisayo, futhi isikhundla sesandla uqobo sihlala singashintshiwe.
Amanani okugeleza ayahlukahluka, ngama-valves ama-valves adinga ukuvalwa okugcwele noma okugcwele, kanti ama-valves omhlaba awenzi. I-Valve Valve ine-inlet inlet ne-inlet ecacisiwe, futhi i-valua valve ayinazo izidingo zokuqondisa ukuthumela.
Ngaphezu kwalokho, i-valurve valve ivulekile ngokuphelele noma ivale ngokuphelele izifunda ezimbili, ukuvulwa kwesango nokuvalwa kwesango kukhulu kakhulu, isikhathi sokuvula nokuvala sinde. I-valve Plate Movement Stroke ye-Valve Valve incane kakhulu, futhi ipuleti ye-valve ye-valve ye-Globalve ingama endaweni ethile ihamba ngokulungiswa kokugeleza. I-valulve valve ingasetshenziselwa kuphela ukuncishiswa futhi ayinawo omunye umsebenzi.
- Ukwenza
I-valve ye-genemve valve ingasetshenziselwa ukukhishwa kanye nomthethonqubo wokugeleza. Ukumelana koketshezi kwe-valve ye-globalve kukhulu, futhi kunzima kakhulu ukuvula nokuvala, kepha ngoba ipuleti le-valve lifushane kusukela endaweni yokubopha, ukuvulwa nokuvala unhlangothi kufushane.
Ngoba isango le-valu lingavulwa ngokuphelele futhi livalwe ngokuphelele, lapho livulwa ngokuphelele, ukumelana nokugeleza okuphakathi esiteshini somzimba se-valve kucishe kube ngu-0, kodwa ukuvalwa kwesango kukude kakhulu nangokwesivalo, futhi isikhathi sesango sikude.
- Ukufakwa nokugeleza kokuqondisa
Umphumela we-valulve valve egeleza kuzo zombili izinkomba uyefana, futhi akukho sidingo sokungenela nokuphuma kokufakwa kokufakwa, futhi eliphakathi lingageleza kuzo zombili izinkomba. I-valve ye-Globalve Valve idinga ukufakwa ngokuqinile ngokuqondiswa kokukhonjwa komqondo womzimba we-valve, futhi kunokuhlinzekwa okucacile ohlangothini lokungenisa ezweni kanye nokuhola kwe-valve ye-Global Valve "ezintathu kuya" eChina kusuka phezulu kuya phansi.
I-valve ye-hlaba i-globalve iphansi ngaphakathi nangaphandle, futhi ukusuka ngaphandle kukhona amapayipi asobala okungewona esigabeni. I-Gate Valve Runer iselayini ovundlile. Isifo sohlangothi se-valurve valve sikhulu kunalokho kwe-valve ye-hlaba.
Ngokombono wokumelana nokugeleza, ukumelana nokugeleza kwe-valulve valve kuncane lapho kuvuleka ngokuphelele, futhi ukumelana nokugeleza kwe-fall stop valve kukhulu. I-coufficience yokugwinya ephathelene ne-valve yesango elijwayelekile imayelana no-0.08 ~ 0.12, amandla okuvulwa nawokuvala incane, futhi eliphakathi lingageleza ngezindlela ezimbili. Ukuvuselelwa kokugeleza kwama-valve ajwayelekile avaliwe kuhlale izikhathi ezi-3-5 ezinama-valves wesango. Lapho uvula futhi uvala, kuyadingeka ukuphoqa ukuvalwa ukufezekisa uphawu, i-valve spool ye-global valve ihlangana kuphela, ngoba ukugeleza komhlaba okuphelele kudinga ukwengeza umbhalisi we-globe valve kufanele anake ukulungiswa kwe-torque control mechage.
I-Valve Valve inezindlela ezimbili zokufaka, eyodwa ukuthi i-Medium ingangena ngaphansi kwe-valve spool, inzuzo iwukuthi lapho i-valve ivaliwe, futhi umsebenzi wokufaka esikhundleni, futhi umsebenzi wokufaka esikhundleni sokuphangwa ungangenwe, futhi umsebenzi wokufaka esikhundleni sokuphangwa ungangenwe, futhi umsebenzi wokufaka esikhundleni sokuphangwa ungangenziwa ngaphansi kwengcindezi epanini phambi kwe-valve; Okubi ukuthi i-torque yokushayela ye-valve inkulu, ecishe ibe izikhathi ezi-1 ezenziwa yi-axial yesiqu se-valve inkulu, futhi i-valve stem kulula ukuyiguqa.
Ngakho-ke, le ndlela ngokuvamile ilungele kuphela ama-valves amancane-ububanzi kuphela (i-DN50 noma ngaphansi), futhi ama-valves e-Global Vales akhethwe nge-DN200 akhethiwe ngendlela yezindaba ezigelezelwa ngaphezulu. (Ama-valves avaliwe kagesi ngokuvamile asebenzisa i-medium ukungena ngenhla.) Ububi bendlela abezindaba abangenayo kusuka phezulu baphambene nendlela engenela ngayo ngezansi.
- Ukuhlalisa
Indawo ebekelwe uphawu le-valve ye-hlabamhlaba inguhlangothi oluncane lwe-trapezoidal lwe-valve core (bheka ngqo ukwakheka kwe-valve core), uma umehluko we-valve ungenasici, kepha umphumela wengcindezi awukubi, umphumela wokuvilapha uvalwe eceleni kwe-valve core plate, umphumela we-bacve I-Valve, kanye ne-Valve Core ngeke iwele njenge-valve ye-hlaba.
