Amavalvu ezicelo zegesi yesulfure encibilikisiwe noma igesi yomsila wesulfure-August 2019-Amavalvu nokuzenzakalelayo

Onjiniyela bakaZwick abaklami baye baxazulula izinkinga eziqhubekayo ama-valve embonini yesibabule. Emapayipini anobubanzi obukhulu, izinkinga ezijwayelekile zamavalvu zisukela ezivaleni ezinamathelayo kuye ekulimaleni okukhulu kwesihlalo sevalvu (lapho ivalvu idinga ukusebenza ngemva kwesikhathi eside ingasebenzi). I-valve kufanele iqokwe njengejakhethi ye-steam ngoba lokhu kuyisidingo se-valve esiyisibopho sezinga. Ngokuvamile, amavalvu avamile angase afanelekele amapayipi afanelekile lapho kungeke kuphinde kube khona isikhathi sokuphumula noma amaqhubu, ngoba uma izinga lokushisa lomzimba wevalvu selifinyelele izinga lokushisa lomzimba wesulfure eshisayo noma igesi yokukhipha umoya ephuma kuyo, akukho ukuqiniswa okuyovunyelwa. Lapho umzimba we-valve nawo upholile ngenxa yokupholisa isibabule, kwenzeka isimo esingavamile, esibe sesiqina endaweni ye-bearing/shaft, ngaleyo ndlela kugxumeke lezi zakhi. Ngokusekelwe kokuhlangenwe nakho kwamazwe ngamazwe, onjiniyela bakwaZwick batusa ukusetshenziswa kwama-valve anejakhethi yesitimu ngoba angakwazi ukugcina izindawo ezibucayi ezingeni lokushisa elingashintshi, ngaleyo ndlela aqede noma yikuphi ukuquleka okungenzeka. Inkampani ingahlinzeka ngama-valve angama-wafer nama-flange aphindwe kabili anamajakhethi esitimu, futhi singasebenzisa nezicucu zamavalvu okulandelela umusi (isiqu nediski). Amavalvu ochungechunge lweZwick Tri-Con afakwe izivikeli ezithwalayo, ezinganciphisa okuphakathi ukungena ezindaweni ezibucayi, kanye nechweba elidonsa amanzi, kuhlanganisa ukuhlanza nokuvikela kwangempela kwalezi zindawo ezibalulekile. Incazelo elandelayo igqamisa umehluko wobuchwepheshe phakathi kwe-Zwick Tri-Con valve nezinye izinhlobo (kusuka ku-valve eccentric ephindwe kabili ukuya ku-valve engenajakhethi), ezohluleka kulolu hlobo lohlelo. Uchungechunge lwe-Tri-Con luklanyelwe ngokukhethekile ukuhlukaniswa kwenqubo, ukuvula/ukuvala kanye namavalvu okulawula. Ububanzi bayo bezinhlelo zokusebenza bukhawulelwe kuphela ngezinto zangempela ezisetshenzisiwe. Eqinisweni, ama-valve akhiqizwa iZwick afanele izinga lokushisa elingu--196ºC kuya phezulu kuya ku-+815ºC. Amavalvu angenziwa nganoma yiliphi ifomu lengxubevange elisebenzisekayo ukuze ahlangabezane nezidingo ezithile zamakhasimende. Uchungechunge lweZwick Tri-Con luyi-valve eccentric ephindwe kathathu enekhoni yangempela kanye nedizayini yekhoni yangaphakathi, engaqeda noma yikuphi ukungqubuzana kwesihlalo sevalvu, ngaleyo ndlela isuse noma yikuphi ukugqokwa okungase kubangele ukuvuza. Kwamanye ama-valve asebenza kahle kakhulu, lokhu ngokwezobuchwepheshe akunakwenzeka, njengokuklama kwe-eccentric ephindwe kabili. Ngokuhamba kwesikhathi, i-15-18º friction seal yokugcina izovuza. Ama-valve ane-eccentric ephindwe kabili awafanele lezi zinhlelo zokusebenza ezidingekayo. Ngakho-ke, noma yimuphi umzamo wokuzisebenzisa ungase uholele emiphumeleni eyinkinga. I-self-centering disc: Ngediski yayo yesinxephezelo sokushisa esizibekela yona eyingqayizivele, isakhiwo sochungechunge lwe-Tri-Con singaqinisekisa indawo engcono kakhulu yophawu olune-laminated ngokuhlobene nesihlalo sevalvu. Ngakho-ke, ukuphazamiseka okubangelwa ukwanda kokushisa kuyaqedwa. Ukudluliswa kwe-torque ngokhiye: I-disc ifakwe ku-shaft futhi ayigxili, ihlinzeka ngokudluliswa kwe-torque efanayo futhi isusa ubungozi bokuwa kwezikhonkwane. Ifilimu ekahle nedizayini yediski: I-disc eqinile kanye nendawo yayo esekela i-elliptical inikeza umphumela omuhle kakhulu wokulungisa ifilimu. Ngokucutshungulwa okukhethekile kwama-laminates, ukuvuza kwe-zero kungafinyelelwa. Ukusekela i-bearing bushing: Indawo efanelekile yokuthwala inciphisa ukugoba kwe-shaft. Lokhu kungaqinisekisa ukuvalwa kwezindlela ezimbili ngaphansi kwengcindezi enkulu.
