Umthengisi we-valve yesango le-intshi ezingama-64 yoMzi-mveliso waseTshayina oMgangatho oPhezulu
Yintoni ivalvu yesango engama-intshi angama-64?
Ivalvu yesango le-intshi ezingama-64,indlela yokusebenza ephambili kunye noomatshini efanayo neevalvu zesango ze-API600 wedge eziqhelekileyo.Ivalvu yesango le-wedge inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kuphela kwaye ayinakulungiswa kwaye iqhotyiswe. Ivalvu yesango yenzelwe ukusetyenziswa nokuba ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, kuba ngenxa yesimo see-obturators zayo ezinesimo se-wedge, ukuba ibisebenza ivuliwe kancinci, bekuya kubakho ukulahleka okukhulu koxinzelelo kwaye umphezulu wokutywina uya konakaliswa xa kuchaphazeleka lulwelo.Kwakhona iyilwe kwaye yenziwa ngokwe-American standard API600, ASME B16.34, isiphelo sayo esijikelezileyo kwi-ASME B 16.5, kwaye yavavanywa ngokwe-API598, inomsebenzi othile nolinganiselweyo wokukhulula okanye ukuthintela ukuhamba kweentlobo ezahlukeneyo zolwelo kwimibhobho.
kodwa ifuna amandla angakumbi ukuvelisa iivalvu zesango ezinkulu ze-API600.
- 1) inkqubo yokubumba: iseti epheleleyo yokubumba okukhulu komzimba wonke, ibhonethi, i-wedge njl.
- 2) izixhobo: ukuchaneka okuphezulu iilathe ezithe nkqo, ukubhola, oomatshini bokugaya ubukhulu obukhulu.
- 3) iingcali zobugcisa kunye nabasebenzi abanezakhono: kunzima kakhulu ukwenza iivalvu zesango ezinkulu
Iimpawu eziphambili zevalvu yesango le-intshi ezingama-64
Iimpawu eziphambili
- 1) Ubungakanani obukhulu ukuya kuthi ga kwi-72" (DN1800), kunye noxinzelelo oluphezulu lokusebenza ukuya kuthi ga kwi-2500lbs
- 2) I-wedge eguquguqukayo enomgca ophakathi ophantsi, kwi-CA15 eqinileyo (13Cr) okanye eqinileyo nge-13Cr, SS 316, Monel okanye Stellite Gr.6. I-wedge iyagaywa kwaye idityaniswe kwisipili kwaye ikhokelwa ngokuqinileyo ukuthintela ukurhuqwa kunye nokonakala kwesihlalo.
- 3) I-trim eqhelekileyo: I-API trim 1 (13Cr), i-trim 5 (i-Stellite Gr.6 ejongene ne-wedge kunye nesihlalo) kunye ne-trim 8 (i-Stellite Gr.6 ejongene nesihlalo) ziyafumaneka. kunye nezinye iinombolo ze-trim kuxhomekeke kwizixhobo zomzimba ezikhethiweyo.
- 7) Ubuso besihlalo buqinile, bucoliwe kwaye bubekwe ecaleni kwesipili.I-wedge ye-CF8M ene-Stellite eqinileyo nayo iyafumaneka xa uyicela.
