I-Stainless Steel API Flanged Globe valve

Siyimboni ye-valve enolwazi enezitifiketi ze-ISO, CE kanye ne-API esandleni. Sinemishini yokukhiqiza ephelele kanye nokuhlola okuqinile kwekhwalithi egcwele. Siphinde sithathe izicelo ze-OEM ne-ODM ezinobuncane be-oda obuvumelana nezimo. Ama-valve ethu ahlala isikhathi eside athunyelwa emazweni emhlabeni wonke futhi azuza impendulo engaguquki evela kubathengi.

Izimfanelo Ezibalulekile

Iyini inzuzo yamavalvu eglobhu ajwayelekile e-API ngaphezu kwamavalvu embulunga ajwayelekile?

Le valve yembulunga yakhiwe ngokuhambisana ngokuqinile nezindinganiso zezimboni ze-API zamapayipi e-petroleum namakhemikhali. Ukuqina kodonga lwayo, ukwakheka kokuvala, amandla okuthwala ingcindezi kanye nezindinganiso zokuhlola izinto ezibonakalayo ziqine kakhulu kunamavalvu avamile avamile. Ingakwazi ukubekezelela ukucindezela okukhulu kwesikhathi eside, ukuvulwa nokuvalwa njalo kanye nomthelela ovela ekugelezeni okuphakathi, futhi ihlangabezana nezidingo zesitifiketi samafutha, igesi namaphrojekthi amakhulu amakhemikhali. Amavalvu ajwayelekile ahlangabezana kuphela namazinga ajwayelekile okunikezwa kwamanzi kanye ne-drainage futhi awakwazi ukudlula ukwamukelwa okuqinile kobunjiniyela be-API.

Yiziphi izinhlobo ze-medium le API yensimbi engagqwali engathuthwa ngayo?

Umzimba we-valve yensimbi engagqwali uletha ukusebenza okuvelele kwe-anti-rust kanye ne-anti-corrosion. Ingadlulisa ngokuphepha uwoyela ongahluziwe, igesi yemvelo, isitimu esinezinga eliphezulu lokushisa, amanzi azungezayo ezimbonini, amanzi olwandle, amanzi olwandle, amanzi anosawoti, i-asidi ebuthakathaka kanye noketshezi lwamakhemikhali e-alkali olubuthakathaka. Ayifanele imidiya egqwalile eqinile ene-oxidizing; uma udinga ukuthutha uketshezi olukhethekile olunjalo, singakwazi ukwenza ngokwezifiso ukupholisha kwesibuko kanye nezingxenye ezikhethekile zokuvala uphawu ezimelene nawe.

Ingabe le valve ye-Stainless Steel API Flanged Globe isetshenziselwa ukuvalwa okuphelele noma ukulawula ukugeleza kuphela?

Inemisebenzi embaxambili yokunqanyulwa okugcwele nokugeleza okunembayo, okuyisici sayo esiyinhloko esihlukile kumavalvu ebhola. I-trim eyakhelwe ngaphakathi elungisekayo ingashintsha indawo yokugeleza ngokuzinzile. Ungakwazi ukulungisa kahle isivinini sokugeleza okumaphakathi kanye nomfutho wepayipi ngaphandle kokugeleza okuzumayo. Uma ivalwe ngokugcwele, ifinyelela ukuvalwa okuqinile okuthembekile ukuze ihlukanise amapayipi okushintsha nokugcinwa kwemishini.

Imaphi amakilasi okucindezela kanye nobubanzi bezinga lokushisa le valve ye-Stainless Steel API Flanged Globe isekela?

Sinikezela ngamamaki okucindezela kwe-API ajwayelekile: Ikilasi 150, 300, 600,900,1500. Izinga lokushisa elisebenzayo elisebenzayo lisukela ku -29℃ ukuya ku-425℃. Insimbi engagqwali igcina ukuqina kwemishini okuzinzile ngaphansi kwezindawo ezinezinga lokushisa eliphansi futhi ngeke ikhubazeke noma ilahlekelwe ukumelana nengcindezi ngaphansi kwezimo zokusebenza zesikhathi eside ezisezingeni eliphezulu.

Yiziphi izici ze-flange ongazikhiqiza?

Ukucushwa okujwayelekile ama-API ANSI ama-flange obuso obuphakanyisiwe (RF). Ama-flat face flange (FF) angakhethwa uma ecelwa. Uma ipayipi lakho elisendaweni lisebenzisa izikhala zembobo yebhawodi okungajwayelekile, ububanzi obukhethekile obungaphandle noma ukujiya, singacubungula kabusha usayizi wokubhoboza i-flange ngokwemidwebo yakho ukuze sifinyelele ukumeshana okuphelele namapayipi akho.

Yiziphi izinketho zokuvala ezitholakalayo ezimweni ezehlukene zokusebenza?

Izikimu ezintathu zokuvala ezivuthiwe zezimo ezihlukahlukene zokusebenza:

Uphawu oluthambile lwe-PTFE: Ukuvuza okunguziro, ukungqubuzana okuphansi nokumelana nokugqwala okuhle, kulungele izinga lokushisa elivamile namapayipi oketshezi anomfutho ophansi

I-Flexible graphite seal: Izinga lokushisa eliphezulu kakhulu nokusebenza okunqanda ukuguga, ukukhetha okungcono kakhulu kwamapayipi esitimu esishisayo athatha isikhathi eside

Ukuhlanganiswa kwe-Metal hard seal: Ukumelana nokugqokwa okuqinile nokumelana nokucindezela okuphezulu, kusebenza endaweni enengcindezi ephezulu equkethe izinhlayiya ezincane eziqinile, okugcina umphumela wokuvala ozinzile iminyaka yokusebenza okuqhubekayo.

Yiziphi izinqubo zokuhlola ezizodlula zonke i-valve ngaphambi kokulethwa?

Senza ukuhlola okuphelele komuntu ngamunye esikhundleni samasampula okungahleliwe awo wonke ama-valve aphelile. Ukuhlola okuphoqelekile kuhlanganisa ukuhlolwa kwamandla egobolondo le-hydrostatic pressure, ukuhlolwa kokuqina komoya kwangaphakathi nangaphandle, ukuhlolwa kokusebenza kokuvala kanye nokuhlola ukuguquguquka kokuvula-ukuvala. Izitifiketi eziphelele zokuhlolwa kwezinto kanye nemibiko yokuhlola ejwayelekile ye-API inganikezwa mahhala uma uyicela.

Kungani ukhetha ukuxhumana okune-flanged esikhundleni sevalvu yeglobu ye-API enentambo?

Uxhumano lwe-API flanged lunokuxhumana okukhudlwana okuvalekayo, ukumelana nokucindezela okuphelele okuqinile kanye nokuqina okuzinzile ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu, okuvimbela ngempumelelo ukuvuza okuphakathi. Ukufakwa, ukuqaqa kanye nomsebenzi wokulungisa nsuku zonke kulula ngaphandle kwe-tape yokufaka uphawu. Idizayinelwe amapayipi amakhulu ezimboni anemisebenzi enzima anamahora amade aqhubekayo, kuyilapho ama-valve anentambo efanele kuphela amapayipi asizayo anezibhobo ezincane, anengcindezi ephansi.
