Isishwankathelo

Ivalvu yebhabhathane ye-NSEN Weld ephindwe kathathu inokubonelela ngokutywinwa okufakwe ilaminate kunye nokutywinwa kwesinyithi ngokupheleleyo. Umzimba oqingqiweyo uza kusetyenziswa kolu luhlu, ungathintela ukukhululeka kwangaphakathi okungabonakaliyo ngexesha lenkqubo yokuphosa kunye neziphene zamandla omzimba kunye namandla e-axial ngenkqubo yokutywina ipleyiti. Uhlolo lwe-NDE luya kwenziwa ukuba abathengi bacele, singabonelela ngenkonzo yokuyilungiselela.

Ukumakishwa kweValve:I-MSS-SP-25

Uyilo kunye noMveliso:I-API 609, EN 593

Uqhagamshelo Lokuphela:I-ASME B16.25

Uvavanyo kunye nokuhlolwa:I-API 598, EN 12266, ISO 5208

Ulwakhiwo

Ivalvu yebhabhathane ephindwe kathathu yongeza i-eccentric yesithathu esekwe kwisakhiwo esiphindwe kabini. I-eccentric yesithathu ine-engile ethile phakathi komgca osembindini womzimba wevalvu kunye nobuso bokutywina isihlalo esijijekileyo, iqinisekisa ukuba iringi yokutywina yediski inokwahlulwa okanye ichukunyiswe nesihlalo ngokukhawuleza ukuze ukungqubana kunye nokuxinana phakathi kwesihlalo kunye neringi yokutywina kususwe.

Uyilo olungenangxabano

Ukusetyenziswa kwesakhiwo se-triple eccentric kunciphisa ukungqubana ngexesha lokutshintsha phakathi komphezulu wokutywina wediski kunye nomzimba wevalvu, ukuze idiski ikwazi ukukhupha ngokukhawuleza isihlalo sevalvu xa ivalvu yebhabhathane ye-triple eccentric ivuliwe okanye ivaliwe.

I-torque evulekileyo ephantsi

Olu luhlu lusebenzisa iRadial Dynamically Balanced Sealing System, ngoyilo olucwangcisiweyo, amandla asetyenziswa kumacala omabini okungena kunye nokuphuma kwediski yebhabhathane ayalingana ukuze anciphise ngempumelelo i-torque yokuvula ivalvu.

Ibheyari etyetyisiweyo

Ukuze kuncitshiswe i-torque yokusebenza kwaye kuthintelwe ukutshixeka kwesiqu phantsi kokuvulwa nokuvalwa rhoqo, kufakwe i-bushing yokuzithambisa eyenzelwe wena.

Uyilo lwesiqu oluthintela ukuqhushumba

Ivalvu nganye yongeza uyilo olungenakukhupha umoya kwindawo yesiqu ngokwe-API609 eqhelekileyo.

Mi-aterial        
Indandatho yesitywino yohlobo lwe-laminated yenziwe ngepleyiti yentsimbi engagqwaliyo enegrafiti/ifayibha yekhabhoni/i-PTFE njl. Xa kuthelekiswa nezinto zepleyiti ye-asbestos zerabha, izinto zethu zokwamkela ziyanxitywa ngakumbi, azigugi, zithembekile kwaye zingcono kwindalo esingqongileyo.

Iseti yesihlalo eyenziwe ngevalvu yebhabhathane etywiniweyo yenziwe ngentsimbi ye-alloy eyenziwe ngobuchule enezibonelelo zokuchasana nokukhuhla, ukumelana nokuguguleka, uxinzelelo oluphezulu kunye nokumelana nobushushu kunye nobomi obude.

Izinto zokucheba zenziwe ngentsimbi engagqwaliyo ekumgangatho ophezulu, zinokuphepha ingxaki yokugqwala emva kokusetyenziswa ixesha elide.

Amandla eSithili:Isikhululo samandla obushushu, isikhululo sokutshintshiselana kobushushu, isityalo sebhoyila sengingqi, iluphu yamanzi ashushu, inkqubo yepayipi yesiqu

Umatshini wokucoca:I-Brine, Umphunga we-carbon dioxide, isityalo se-propylene, inkqubo yomphunga, igesi ye-propylene, isityalo se-ethylene, isixhobo sokuqhekeka kwe-ethylene, isityalo sokucola

Isikhululo samandla enyukliya:ukwahlulwa kogcino, inkqubo yokukhupha ityuwa emanzini olwandle, inkqubo yetyuwa, inkqubo yokutshiza ephambili, ukwahlulwa kwepompo

Ukuveliswa kwamandla obushushu: ukupholisa i-condenser, ukwahlula i-pump kunye ne-steam extraction, i-heat exchanger, ukwahlukanisa i-condenser cooling, ukwahlukanisa i-pump

Ubushushu obuphantsi:igesi engamanzi, iinkqubo zegesi yendalo enyibilikisiweyo, iinkqubo zokubuyisela ioyile, izityalo zokufaka igesi kunye nezixhobo zokugcina, iinkqubo zokuthutha igesi yendalo enyibilikisiweyo

Intlama kunye nephepha:ukwahlulwa komphunga, amanzi ebhoyila, ilayimu kunye nodaka

Ukucocwa kweoyile:Ukwahlulwa kweoyile, ivalvu yokuhambisa umoya, inkqubo yokukhupha i-sulfurization kunye neprosesa yegesi emdaka, igesi yokutsha, ukwahlulwa kwegesi ye-asidi, i-FCCU

Igesi yendalo

I-NSEN ilandela ngokungqongqo iinkonzo zokulungisa zasimahla, ukutshintshwa kwasimahla kunye nokubuyiselwa kwasimahla kwiinyanga ezili-18 emva kokuba ivalvu ingasebenzi okanye iinyanga ezili-12 emva kokufakwa nokusetyenziswa kwipayipi emva kokusebenza kwangaphambili (ekuza kuqala). 

Kwimeko apho ivalvu iye yawa ngenxa yengxaki yomgangatho ngexesha lokusetyenziswa kwipayipi ngexesha lewaranti yomgangatho, i-NSEN iya kubonelela ngenkonzo yewaranti yomgangatho yasimahla. Inkonzo ayizukuphela de kube ukusilela kulungisiwe kwaye ivalvu iyasebenza kwaye umthengi utyikitye ileta yokuqinisekisa.

Emva kokuphela kwexesha elichaziweyo, i-NSEN iqinisekisa ukubonelela abasebenzisi ngeenkonzo zobugcisa ezisemgangathweni ngexesha nanini na xa imveliso ifuna ukulungiswa nokugcinwa.
