I-Carbon Steel National Standard Flange Gate Valve

Singumenzi wamavalvu ochwepheshe ophethe izitifiketi ze-ISO, API kanye ne-CE. Siphethe imishini yokukhiqiza ethuthukisiwe kanye nesethi egcwele yezinhlelo zokulawula ikhwalithi. Futhi samukela ama-oda we-OEM ne-ODM, anamanani amancane avumelana nezimo. Imikhiqizo yethu ethembekile ithunyelwa emhlabeni wonke futhi izuza ukuqashelwa okubanzi kumakhasimende.

Ayini ama-flange ensimbi e-carbon standard yama-valve esango?

Ama-flange ensimbi ye-carbon afika ngaphansi kwamazinga ahlukene kuye ngokuthi uwasebenzisa kuphi. Ezivamile zifaka i-ASME B16.5 (izinga laseMelika), EN 1092-1 (izinga laseYurophu), kanye nochungechunge lwe-GB/T 9113 (okujwayelekile kwezwe laseShayina). Kumavalvu esango lesango le-carbon steel standard kazwelonke, ngokuvamile silandela izindinganiso ze-GB ukufanisa amapayipi asekhaya. Lawa mazinga achaza usayizi we-flange, isilinganiso sokucindezela, kanye nephethini yembobo yebholithi, ukuze i-valve ilingane kahle namapayipi akho futhi ihlangabezane nesigaba sokucindezela esidingekayo.

Izimfanelo Ezibalulekile

Yiziphi izindinganiso ezisebenza kuma-valve esango?

Ama-valve esango awenziwanga wonke ayafana—alandela izindinganiso ezihlukene kuye ngokuthi uhlela ukuwasebenzisa kuphi futhi kanjani. Emisebenzini enzima efana nokuhluza uwoyela negesi, i-API 600 iyindinganiso eyinhloko yamavalvu esango lensimbi esindayo. I-ISO 6002 ingenye indinganiso yamazwe ngamazwe ehambisana ne-API 600 yezinhlobo zebhonethi eboshiwe. Futhi kumaphrojekthi ethu asekhaya namaningi ajwayelekile ezimboni, sisebenzisa indinganiso yaseChina ye-GB/T 12234. Ngalinye lalawa mazinga lichaza kahle ukuthi i-valve kufanele iklanywe kanjani, yiziphi izinto okufanele zisetshenziswe, ukuthi ihlolelwa kanjani ingcindezi, kanye nobukhulu ozothola. Ngaleyo ndlela, uyazi ukuthi i-valve izolingana nomugqa wakho futhi ibambe ngokuphepha ngokuhamba kwesikhathi.

Iyiphi indima edlalwa i-flange ku-valve yesango?

I-flange ngokuyisisekelo "ubuso bokuxhuma" ekupheleni kwevalve yesango. Yilokho okukuvumela ukuthi uvale i-valve ngqo epayipini lakho noma kwezinye izinto zokusebenza. Uma uqinisa amabhawodi, i-flange icindezela ngokulinganayo ku-gasket ukuze yenze uphawu oluqinile, olungavuzi. Lokho kusho ukuthi akukho ukuvuza okungcolile, futhi kamuva uma udinga ukukhipha ivalvu ukuze ilungiswe noma ishintshwe, kulula ngempela ukuyivula nokuyisusa. I-flange iphinde isakaze ingcindezi yokusebenza ngokulinganayo kuyo yonke indawo, ngakho uxhumano luhlala luzinzile ngisho nalapho isistimu ingaphansi komthwalo.

Ungakwazi yini ukuchaza izinga le-API 600?

I-API 600 iyindinganiso eqinile, engenangqondo evela ku-American Petroleum Institute. Yenzelwe ngokukhethekile amavalvu esango lensimbi yebhonethi eboshiwe—uhlobo oluthola ezindaweni zokucwenga, amapayipi kawoyela negesi, nezinye izindawo zezimboni ezifuna ngempela.

Ayinqamuki ezimweni ezidingekayo: ukukhetha kwezinto ezibonakalayo kufanele kube okulungile, umklamo kufanele ubambelele, ukukhiqiza kufanele kulandele imithetho eqinile, futhi wonke ama-valve kufanele adlule ingcindezi kanye nokuhlolwa kokuvuza ngaphambi kokuba aphume efektri. Iphuzu lonke lilula: qiniseka ukuthi i-valve ingathatha ukucindezela okuphezulu, ukushisa okuphezulu, nemidiya enzima, futhi isasebenza uma uyidinga kakhulu. Uma i-valve yesango ihlangana ne-API 600, uyazi ukuthi yakhelwe izinhlelo zokusebenza ezibucayi, ezisebenza kanzima.
