Ingxenye yokuvula neyokuvala yamavalvu esango lensimbi efojiwe yipuleti lesango, futhi isiqondiso sokuhamba kwepuleti lesango libhekene nesiqondiso soketshezi. Amavalvu esango ensimbi enziwe mbumbulu angavuleka ngokugcwele futhi avalwe ngokugcwele, futhi awakwazi ukulungiswa noma ukuphonswa. Ipuleti lesango le-valve yesango lensimbi efojiwe linezindawo ezimbili zokuvala, futhi imodi evame ukusetshenziswa kakhulu yevalvu yesango ukuthi izindawo ezimbili zokuvala zakha umumo we-wedge, futhi i-engeli ye-wedge iyahlukahluka ngemingcele ye-valve.

    Xhumana nathi
    imininingwane yomkhiqizo

    Ivalvu yesango yensimbi eyenziwe ngomgunyathi isho ivalvu isango layo elihamba liqonde emgqeni omaphakathi wephaseji. Ama-valve esango ensimbi enziwe mbumbulu asetshenziswa kakhulu ukusika amapayipi. I-valve yesango lensimbi eyenziwe ngomgunyathi iyi-valve esetshenziswa kabanzi, futhi ngokuvamile isetshenziselwa ukusika izinto ezinobubanzi be-DN ≤ 50. Amavalvu esango ensimbi enziwe ajwayelekile avamile.

    I-Duplex insimbi engagqwali iyinsimbi engagqwali lapho ingxenye yesigaba se-ferrite nengxenye yesigaba se-austenite ikhona esakhiweni sayo sokucisha esiqinile, esinokuqukethwe kwesigaba esincane esingu-30%. I-Duplex insimbi engagqwali yakhiwa ngokwandisa okuqukethwe kwe-Cr noma ukungeza ezinye izakhi ze-ferrite ngesisekelo se-18-8 austenitic stainless steel. Ayinayo nje kuphela i-bi-directional structure ye-austenite ne-ferrite, kodwa futhi igcina i-Ni alloy. Ngenxa yezici zesakhiwo sezigaba ezimbili zensimbi engagqwali eyi-duplex, ngokulawula kahle ukwakheka kwamakhemikhali kanye nenqubo yokwelapha ukushisa, insimbi engagqwali eyi-duplex ingahlanganisa izinzuzo zensimbi engagqwali ye-ferritic kanye ne-austenitic stainless steel. Ukuba khona kwe-austenite kunsimbi engagqwali e-duplex kunciphisa ukuhwalala kwe-Cr ferrite kanye nokuthambekela kokukhula kwekristalu, kuyilapho kugcinwa ukuqina okuhle kakhulu nokusebenza kokushisela; Ukuba khona kwe-ferrite kuthuthukisa amandla okukhiqiza, ukumelana nokugqwala kwe-intergranular, nokumelana nokugqwala kwe-chloride yokucindezeleka kwe-austenite.

    Izici Ezengeziwe

    Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, izinzuzo ze-duplex insimbi engagqwali zimi kanje:

    Okokuqala, amandla okukhiqiza angaphezu kokuphindwe kabili kunawensimbi engagqwali ye-austenitic ejwayelekile, futhi inepulasitiki eyanele kanye nokuqina okudingekayo ekubunjweni. Ubukhulu bodonga lwemikhumbi yokugcina noma yokucindezela eyenziwe nge-duplex insimbi engagqwali iyancipha ngo-30-50% uma kuqhathaniswa ne-austenite evamile, enenzuzo yokunciphisa izindleko.

    Okwesibili, inokumelana okuhle kakhulu nokucindezeleka kokuqhekeka kokugqwala, ngisho nensimbi engagqwali eyi-duplex enokuqukethwe kwe-alloy ephansi inokumelana okuphezulu nokucindezeleka kokuqhekeka kokugqwala kunensimbi engagqwali ye-austenitic, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride. I-stress corrosion inkinga evelele insimbi engagqwali ye-austenitic okunzima ukuyixazulula.

    Okwesithathu, ukumelana nokugqwala kwensimbi engagqwali eyi-2205 duplex, esetshenziswa kakhulu emithonjeni eminingi yezindaba, iphakeme kunaleyo yensimbi engenasici engu-316L austenitic evamile. Insimbi engagqwali eyi-Super duplex inokumelana nokugqwala okuphezulu kakhulu futhi ingafaka esikhundleni sensimbi engagqwali ephezulu ye-alloy austenitic noma ama-alloys amelana nokugqwala kweminye imidiya.

    Okwesine, inokumelana kahle nokugqwala kwendawo. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic enokuqukethwe kwegolide okufanayo, insimbi engagqwali eyi-duplex inokumelana kangcono nokugqokwa kanye nokumelana nokugqwala kokukhathala kunensimbi engagqwali ye-austenitic.

    Okwesihlanu, i-coefficient yokunwetshwa komugqa iphansi kunaleyo ye-austenitic stainless steel, efana ne-carbon steel, ifanele ukuxhunywa ne-carbon steel, futhi inokubaluleka kobunjiniyela okubalulekile, njengokukhiqiza amapuleti ayinhlanganisela noma ama-linings.

    Okwesithupha, kungakhathaliseki ukuthi ngaphansi kwezimo zomthwalo oguquguqukayo noma omile, insimbi engagqwali eyi-duplex inamandla aphezulu okumunca amandla kune-austenitic stainless steel, enenani elisebenzayo lezingxenye zesakhiwo ukubhekana nezingozi ezingalindelekile njengokushayisana nokuqhuma.
