3. Izici Zokwakha
Izici Eziyinhloko Zokwakha:
| Ingxenye | Incazelo Eningiliziwe |
| Umhlangano Wophawu Lwe-Bellows | Izimbozo zensimbi engagqwali ezinezikhonkwane eziningi (ngokuvamile i-SS304, i-SS316L, noma i-Inconel 625) zixhunyelwe esiqwini nasebhonethini, zakha isithiyo esivaliwe esiqeda ukuvuza kwangaphandle. Lesi sakhiwo sinikeza imijikelezo yokusebenza engaphezu kwe-10,000 ngaphandle kokwehluleka, okwandisa kakhulu impilo yevalvu. |
| Umzimba Ohlanganisiwe kanye neBonnet | Umzimba wevalvu kanye nebhonethi kuqiniswe ngokunemba ukuqinisekisa ukugeleza okuphezulu kokusanhlamvu kanye namandla aphezulu omshini. Ukwakhiwa okuqinisiwe kunciphisa ukugoba kanye nokukhubazeka kokubumba, okuholela ekuqineni okuphezulu kokucindezela kanye nokumelana okungcono nokushaqeka kokushisa. |
| Ukuxhumeka kweBhonethi Enebholiti | Ibhonethi eboshiwe ivumela ukufinyelela okulula kokulungiswa ngenkathi iqinisekisa ukugcinwa okuphephile kwengcindezi. Ama-gasket enxeba elijikelezayo noma i-graphite ahlinzeka ngokuvala okungenawo amanzi esibonakalayo somzimba nebhonethi. |
| Umklamo Wesihlalo Sangemuva | Isihlalo sangemuva esenziwe ngomshini onembile ebhonethini sinikeza indawo eyengeziwe yokuvala lapho ivalvu ivuliwe ngokugcwele, ivikela izimbobo kanye nokupakisha ekucindezelweni kwesistimu futhi yandise impilo yesevisi. |
| I-Wedge eguquguqukayo | Umklamo we-wedge oqinile noma oguquguqukayo uqinisekisa ukuvalwa okuqinile futhi ukhokhela ukungahambisani kahle kwesihlalo somzimba okubangelwa ukushintshashintsha kwezinga lokushisa, okunciphisa ingozi yokuminyana. |
| Ukwakhiwa Kwesiqu Nejoka | Isiqu esikhuphukayo sivumela isibonakaliso esibonakalayo sendawo yevalvu. Sisebenza ngomshini oqondile, sigaywe, futhi sicwebezelwe ukuze sisebenze kahle futhi sinciphise ukungqubuzana phakathi kwesiqu kanye nokupakisha. |
| Iziphetho Ezihlanganisiwe Ezihlanganisiwe | Iziphetho zevalvu zenziwa ngomshini ngokwezilinganiso ze-flange ze-ASME B16.5. Izinketho ze-Rised Face (RF) noma i-Ring Type Joint (RTJ) ziyatholakala ukuze kuqinisekiswe ukuqina kokuvala ngokucindezela okuphezulu. |
4. Izinto zokwakha
Ivalvu itholakala ngezinhlobo ezahlukene zezinsimbi ezingagqwali ezenziwe ngobumba ukuze ivumelane nezindawo ezahlukene zokusebenza.
| Ingxenye | Izinketho Zezinto Ezibalulekile (Ibanga le-ASTM / AISI) | Amazwi |
| Umzimba kanye ne-Bonnet | I-ASTM A182 F304 / F304L / F316 / F316L / F321 | Izinsimbi ezingagqwali ezingamelani nokugqwala |
| I-Bellows | SS304, SS316L, Inconel 625 | Umhlangano wezinsimbi eziningi ezishisiwe |
| Idiski/I-Wedge | I-A182 F316 / F316L enezihlalo eziqinile | Imbondela ye-Stellite 6 ongayikhetha |
| Isiqu | A182 F316 / F321 | Umphezulu ophansi nocwebezelayo |
| Indandatho Yesihlalo | I-A276 316L noma i-Stellite | Uhlobo oluhlanganisiwe noma oluhlanganisiwe |
| I-Bonnet Gasket | I-Graphite + SS304 inxeba elijikelezayo | Ukuvalwa kwezinga lokushisa eliphezulu |
| Ukupakisha | I-Graphite noma i-PTFE | Uphawu lwesibili |
| Isondo lesandla | Insimbi yekhabhoni / Insimbi ye-Ductile | Umklamo we-Ergonomic wokusebenza ngesandla |
Izinto zokuzikhethela ezifana ne-Duplex (F51), i-Super Duplex (F53), noma i-Alloy 20 zinganikezwa ngezinhlelo zokusebenza ezikhethekile njengesevisi yegesi emuncu noma i-asidi.
5. Isimiso Sokusebenza
Ivalvu yesango elivalwe nge-bellows isebenza ngokunyakaza okuqondile kwesango le-wedge elivula noma livala indlela yokugeleza. Lapho isondo lesandla liphendulwa ngokuphambene newashi, isiqu siyaphakama, siphakamise isango esihlalweni ukuze kuvunyelwe ukugeleza koketshezi. Ukuguqula isondo lesandla ngokwewashi kwehlisa isango libuyele esihlalweni, kumise ngokuphelele ukugeleza.
Ngesikhathi sokusebenza, izimbobo ziyagobeka nge-axial ngokunyakaza kwesiqu kodwa zigcina uphawu olungenamoya phakathi kwesiqu ne-bonnet. Lokhu kuvimbela noma iyiphi indlela yokusebenza ukuthi ingaphumi endaweni yesiqu - indlela evamile yokuvuza kuma-valve esango avamile.
Ukupakisha i-gland okusizayo kusebenza njengesivalo sesibili kanye nesipele sokuphepha uma kwenzeka ukuqhekeka kwe-bellows, okuqinisekisa ukuqina kokuvala okuqhubekayo.
6. Izinzuzo Eziyinhloko
Ukuvuza Okungazelelwe Emkhathini
I-bellows assembly inikeza ukuvala okuphelele phakathi kwengaphakathi le-valve kanye nendawo ezungezile, kuhambisana nezindinganiso eziqinile zokukhishwa komoya okusabalele njenge-ISO 15848 kanye ne-TA-Luft.
Impilo Ende Yenkonzo
Umklamo wezinsimbi ezihlanganisiwe ezinama-ply amaningi uvumela izinkulungwane zemijikelezo evulekile/evaliwe ngaphandle kokukhathala noma ukuguquka.
Ukuphepha Okuthuthukisiwe kanye Nokuvikelwa Kwemvelo
Ilungele izinto ezinobuthi, ezivuthayo, noma eziyingozi — ukuvimbela ukukhishwa kwegesi ngengozi nokuqinisekisa ukulandelwa kwemithetho yokuphepha.
Ukwakhiwa Kwensimbi Engagqwali Eyenziwe Ngobumba
Inikeza ukumelana okuhle kakhulu nokugqwala, amandla okusebenza, kanye nokuqina okulinganayo ngaphansi kokushisa okuphezulu kanye nengcindezi.
Ukusebenza Okungenazo Izinsizakalo Zokulungisa
Izimbobo ziqeda isidingo sokulungiswa noma ukushintshwa kokupakisha njalo, okunciphisa isikhathi sokungasebenzi kanye nezindleko zokusebenza.
Umklamo Oqinile Nowodwa
Umzimba ohlanganisiwe unikeza ubukhulu obuncane kanye nesisindo esilula uma kuqhathaniswa nama-valve enziwe ngezilinganiso zokucindezela ezifanayo.
Izici Ongakukhetha
Ipulaki yokukhipha amanzi ukuze kungene umoya ovalekile
Ukuxhumeka kwe-By-pass ukuze kulinganiswe ingcindezi
Idivayisi yokukhiya ukuze kuvikelwe indawo
Iphedi yokufaka ye-Actuator yokwenza izinto ngokuzenzakalela
7. Izicelo Ezijwayelekile
I-API Forged Stainless Steel Bellows Sealed Gate Valve ifanelekela ukusetshenziswa okubanzi kwezimboni, ikakhulukazi lapho ukuvimbela ukuvuza kanye nokuphepha kwemvelo kubaluleke kakhulu:
Izindawo Zokuhluza kanye Nezitshalo Ze-Petrochemical - Ukuphatha ama-hydrocarbon, i-H₂S, noma imigqa kawoyela oshisayo
Ukukhiqizwa Kwamandla – Izinhlelo zokuhlukanisa umusi kanye nezokujiya
Ukucubungula Amakhemikhali – Uketshezi olubolayo nolunobuthi
Imboni Yezemithi – Ukulawulwa kwemidiya okumsulwa kakhulu
Izinhlelo ze-Cryogenic kanye ne-Gas - Ukuqinisekisa ukuvalwa okuqinile ngaphansi kokushisa okuphansi
Izinhlelo Zokuhlanza I-Vacuum - Ukugcina ukuqina okuphelele ekusetshenzisweni okuphansi kwengcindezi
8. Ukuhlolwa Nokuhlolwa
I-valve ngayinye ilawulwa izinqubo zokulawula ikhwalithi nokuhlola ngokuqinile ngokwezindinganiso ze-API 598, okuhlanganisa:
Ukuhlolwa kwegobolondo: Ukuhlolwa kokucindezela kwe-hydrostatic kobuqotho bomzimba
Ukuhlolwa Kokuvuza Kwesihlalo: Kuqinisekisa ikhono lokuvala ngokuqinile
Ukuhlolwa Kokuvuza Kwe-Bellows: Ukuhlolwa kokuvuza kwe-Helium kokuqinisekiswa kokungakhiphi komoya
Ukuhlolwa Kokusebenza: Ukuhlolwa komjikelezo wokusebenza okubushelelezi nokuqondanisa isiqu
Ukuhlolwa Okulinganiselwe Nokubonakalayo: Ngokwezindinganiso ze-ASME ne-ASTM
Wonke ama-valve ahlinzekwa ngezitifiketi zokuhlolwa kwezinto ze-EN 10204 3.1, amarekhodi okuhlolwa kwe-hydrostatic, kanye nemibhalo yokulandelela.
