Ukubuka konke

I-valve ye-butterfly ye-NSEN Weld kathathu engase ihlinzeke kokubili ukuvalwa okune-laminated kanye nokuvalwa kwensimbi egcwele. Umzimba ohlanganisiwe uzosetshenziswa kulolu chungechunge, ungagwema ukukhululeka kwangaphakathi okungabonakali ngesikhathi senqubo yokubumba kanye nokukhubazeka kwamandla omzimba kanye namandla e-axial ngenqubo yokushisela ipuleti. Ukuhlolwa kwe-NDE kuzokwenziwa uma kuceliwe ngamakhasimende, singanikeza isevisi yokuyihlela.

• Ukuvalwa okune-laminated kanye nokuvalwa kwensimbi

• I-torque ephansi yokuvula

• Akukho ukuvuza

• Umgodi ongavumeli ukuqhunyiswa

• Akukho ukungqubuzana phakathi kokuvala isihlalo kanye nediski

• Ubuso obugobile bokuvala ikhoni

Ukuklama Nokukhiqiza:I-API 609, EN 593

Ukuxhumana Okuphelile:I-ASME B16.25

Ukuhlolwa Nokuhlolwa:I-API 598, EN 12266, ISO 5208

Isakhiwo

I-valve ye-butterfly e-offset kathathu yengeza i-eccentric yesithathu e-angular esekelwe esakhiweni esi-eccentric esiphindwe kabili. I-offset yesithathu ine-engeli ethile phakathi komugqa ophakathi womzimba we-valve nobuso bokuvala isihlalo obuyi-conical, okuqinisekisa ukuthi indandatho yokuvala yediski ingahlukaniswa noma ithintwe ngesihlalo ngokushesha ukuze ukungqubuzana kanye nokucindezela phakathi kwesihlalo nendandatho yokuvala kuqedwe.

Umklamo ongenazingxabano

Ukusetshenziswa kwesakhiwo se-eccentric esiphindwe kathathu kunciphisa ukungqubuzana ngesikhathi sokushintshana phakathi kobuso bokuvala bediski nomzimba we-valve, ukuze idiski ikwazi ukukhulula ngokushesha isihlalo se-valve lapho i-valve ye-butterfly eccentric kathathu ivulwa noma ivaliwe.

I-torque ephansi yokuvula

Lolu chungechunge lusebenzisa i-Radial Dynamically Balanced Sealing System, ngomklamo olungiselelwe kahle, amandla asetshenziswa kuzo zombili izinhlangothi zokungena kwe-butterfly disc kanye ne-outlet alingana kahle ukuze kwehliswe ngempumelelo i-torque yokuvula i-valve.

Ukuthwala okugcotshwe ngotshani

Ukuze kuncishiswe i-torque yokusebenza futhi kugwenywe ukukhiya kwesiqu ngaphansi kokuvulwa nokuvalwa njalo, kusetshenziswe i-bushing ezigcobayo ezenzelwe wena.

Umklamo wesiqu ovimbela ukuqhunyiswa

Ivalvu ngayinye yengeza umklamo ovikela ukushaqeka endaweni yesiqu ngokwe-API609 ejwayelekile.

Mi-aterial        
Indandatho yesivalo yohlobo lwe-laminated yenziwe ngepuleti lensimbi engagqwali eline-graphite/carbon fiber/PTFE njll. Uma kuqhathaniswa nezinto zepuleti le-asbestos zerabha, izinto zethu zokwamukela ziyagqokwa kalula, azishisi, zithembekile futhi zingcono kakhulu kwezemvelo.

Indandatho yesihlalo eyenziwe nge-valve ye-butterfly evalwe ngensimbi yenziwe ngensimbi eyenziwe nge-alloy enezinzuzo zokulwa nokukhuhla, ukumelana nokuguguleka, ukumelana nokucindezela okuphezulu kanye nokushisa kanye nokuphila isikhathi eside.

Izinto zokuhlobisa zenziwe ngensimbi engagqwali esezingeni eliphezulu, zingagwema inkinga yokugqwala ngemva kokusetshenziswa isikhathi eside.

Amandla esifunda:Isiteshi sikagesi esishisayo, isiteshi sokushintshanisa ukushisa, isitshalo sebhoyila sesifunda, iluphu yamanzi ashisayo, uhlelo lwepayipi eliyisisekelo

Indawo yokuhluza:I-Brine, Umhwamuko we-Carbon dioxide, isitshalo se-propylene, uhlelo lomhwamuko, igesi ye-propylene, isitshalo se-ethylene, idivayisi yokuqhekeka kwe-ethylene, isitshalo sokuphehla

Isikhungo samandla enuzi:ukuhlukaniswa kokuqukethwe, uhlelo lokukhipha usawoti emanzini olwandle, uhlelo lwe-brine, uhlelo lokufafaza oluyinhloko, ukuhlukaniswa kwephampu

Ukukhiqizwa kwamandla okushisa: ukupholisa i-condenser, ukuhlukaniswa kwephampu kanye nokukhishwa komusi, i-heat exchanger, ukuhlukaniswa kokupholisa i-condenser, ukuhlukaniswa kwephampu

Izinga lokushisa eliphansi:igesi ewuketshezi, izinhlelo zegesi yemvelo encibilikisiwe, izinhlelo zokubuyisa insimu kawoyela, izitshalo zokufaka igesi kanye nemishini yokugcina, izinhlelo zokuthutha igesi yemvelo encibilikisiwe

I-Pulp nephepha:ukuhlukaniswa komusi, amanzi abilayo, ilayisi nodaka

Ukuhluzwa kwamafutha:Ukuhlukaniswa kwesitoreji sikawoyela, i-valve yokuhambisa umoya, uhlelo lokususa i-sulfurization kanye neprosesa yegesi elahliwe, igesi evuthayo, ukuhlukaniswa kwegesi ye-asidi, i-FCCU

Igesi yemvelo

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
