Ukusetshenziswa kwe-valve ye-butterfly enkulu enobubanzi obukhulu kuma-valve ezimbonini

(1) Xhuma i-valve ngentambo. Lokhu KUXHUMANA KUVAMISE UKWENZA IMISHINI

I-ALVE INLET KANYE NE-OUTLET IGCINWA NGEMICHUNGE YAMAPHAYIBHI E-TAPERED NOMA OKUQONDILE ENGAHLANGANISWA OKUHLANGANISIWE OKUHLANGANISIWE NOMUCHUNGO WAMABHAYIBHILE. Ngenxa yokuthi kungenzeka ukuthi kube neziteshi ezinkulu zokuvuza kulokhu kuxhumana, lezi ziteshi zingavinjwa nge-sealant, i-sealing tape, noma ukupakisha. Uma impahla ye-valve yomzimba ingashiswa, kodwa i-coefficient yokwandisa ihluke kakhulu, noma ububanzi bokuhlukahluka kokushisa okusebenzayo bukhulu, uxhumano oluhlanganisiwe kufanele lube uju oluvalwe nge-welding.
Ukuxhumana okunentambo kwevalvu ngokuyinhloko kuyi-meridian yegama kuvalvu elandelayo engu-50mm. Uma ubukhulu be-diameter bukhulu kakhulu, kunzima kakhulu ukufaka nokuvala i-joint.
Ukuze kube lula ukufakwa nokususwa kwama-valve anentambo, izixhumi ziyatholakala ezindaweni ezifanele ohlelweni lwamapayipi. Amavalvu afika ku-50mm ngosayizi wegama angase asebenzise ilunga lomkhono njengelunga, elinemicu exhuma izingxenye ezimbili zelunga.
(2) I-valve yokuxhuma i-Flange. Ama-valve ane-Flanged kulula ukuwafaka nokuwakhipha. Kodwa makhulu kunama-valve anentambo, futhi abiza kakhulu. Ngakho-ke, kufanelekile ukuxhunywa kwepayipi yobukhulu obuhlukahlukene nezingcindezi. Kodwa-ke, lapho izinga lokushisa lidlula ama-degree angu-350, ngenxa yokuxegiswa kwama-bolts, ama-gaskets nama-flanges, okunciphisa kakhulu umthwalo kuma-bolts, ukuvuza kungase kwenzeke ekuxhumekeni kwe-flange okugcizelelwe kakhulu.
(3) Shisela i-valve. Lokhu kuxhumana kulungele zonke izinhlobo zokucindezela kanye nezinga lokushisa, futhi kunokwethenjelwa kakhulu kunokuxhumeka kwe-flanged uma kusetshenziswa ngaphansi kwezimo ezinzima. Kodwa ukuhlakazwa kwe-valve eshiselwe nokufakwa kabusha kunzima kakhulu, ngakho-ke ukusetshenziswa kwayo kunqunyelwe ngokuvamile kungasebenza ngokwethembeka isikhathi eside, noma ukusebenzisa izimo zokulayisha, izikhathi zokushisa okuphezulu. Njengesiteshi samandla ashisayo, iphrojekthi yamandla enuzi, iphrojekthi ye-ethylene esendleleni.
Amavalvu ashiselwe anobubanzi obungafika ku-50mm ngokuvamile anamajekhi ashiselwe ukubamba ipayipi ekugcineni komthwalo. Ngenxa yokuthi ukushisela isokhethi kwakha igebe phakathi kwesokhethi nepayipi, okungase kubangele ukuthi igebe lidliwe yimithombo ethile, futhi ukudlidliza kwepayipi kuzokwenza ingxenye ehlangene ikhathale, ngakho ukusetshenziswa kwesokhethi yokushisela kulinganiselwe.
Ku-diameter okuzisholo kukhulu, ukusetshenziswa kwezimo zokulayisha, izinga lokushisa eliphezulu, umzimba we-valve uvame ukusebenzisa i-groove welding, ngesikhathi esifanayo, i-welding joint inezidingo zangempela, kufanele ikhethe i-welder eqinile yobuchwepheshe ukuqedela umsebenzi.
I-valve ye-ventilation ye-ventilation enkulu ekusetshenzisweni kwama-valve ezimboni Njengamanje izwe lakithi izimboni ezihlukahlukene ze-valve yensimbi, i-valve esetshenziswa kabanzi ekukhiqizeni i-valve yensimbi esetshenziswe amakhulu eminyaka yomlando, eye ngokusebenzisa ukuthuthukiswa kwesakhiwo nezinto ezibonakalayo, kodwa ukulinganiselwa siqu, izinto zensimbi ziya ngokuya azikwazi ukuzivumelanisa nezimo ezimbi zokusebenza, ukuguga okuqinile okuqinile nokugqwala. Ikakhulukazi ibonakala empilweni yesevisi emfushane, ukuvuza kuthinte kakhulu ukuzinza kokusebenza kwesistimu. I-valve yensimbi yendabuko idinga ngokushesha ukusungulwa okusha kwezinto ezibonakalayo, ukuklama kanye nenqubo yokukhiqiza.
Njengamanje, i-valve evame ukusetshenziswa ekukhiqizeni izimboni ezihlukahlukene ezweni lakithi i-valve yensimbi. Ukusetshenziswa kwe-valve yensimbi sekuneminyaka engaphezu kwekhulu yomlando. Nakuba iye yathuthukiswa ngesakhiwo nezinto zokwakha, ayikwazi ukuhlangabezana nezidingo zokugqoka okuphezulu, ukugqwala okuqinile nezinye izimo zokusebenza ezinzima. Ikakhulukazi ibonakala empilweni yesevisi emfushane, ukuvuza kuthinte kakhulu ukuzinza kokusebenza kwesistimu. I-valve yensimbi yendabuko idinga ngokushesha ukusungulwa okusha kwezinto ezibonakalayo, ukuklama kanye nenqubo yokukhiqiza.
Impahla ye-ceramic ethuthukisiwe, njengento entsha ekhulwini lama-21, ithathwe ngokungathi sína ngabasebenzi besayensi abengeziwe. Kuyindlela emisha enesibindi nenenzuzo ukuyifaka kumavalvu ezimboni.
Izinto ze-Ceramic zine-deformation encane kakhulu namandla okubopha aphakeme kakhulu kunezinsimbi. Ngokuvamile, irediyasi ye-crystalline ionic yezinto zobumba incane, futhi intengo kagesi we-ionic iphezulu, futhi inombolo yokuxhumanisa inkulu. Lezi zakhiwo zinquma amandla okuqina, amandla okucindezela, i-elastic modulus kanye nobulukhuni bezinto zobumba kuphezulu kakhulu. I-Ceramic ngokwayo, nokho, "i-brittle" kanye nokucubungula okunzima ikhawulela ububanzi bayo bokusetshenziswa emashumini eminyaka amuva nje, ngenxa ye-martensitic phase transformation toughening technology, isayensi yezinto ezibonakalayo nobuchwepheshe kanye nokuthuthukiswa nokuqhubeka komqondo we-nanometer ceramics eyenziwe ngobumba kanye ne-porcelain. I-“brittle” ithole * * ukuthuthukisa, ukuqina namandla kuthuthukiswe kakhulu, kunwetshwa ibanga lohlelo lokusebenza.
I-valve ye-ceramic engaguquki isetshenziswa ikakhulukazi kumandla kagesi, i-petroleum, imboni yamakhemikhali, i-metallurgy, izimayini, ukuthuthwa kwendle nezinye izimboni, ikakhulukazi lapho kubhekene nokuguga okuphezulu, ukugqwala okuqinile, izinga lokushisa eliphezulu, ukucindezela okukhulu nezinye izimo zokusebenza ezinzima, kodwa futhi ikhombisa ukusebenza kwayo okuhle kakhulu. Ingakwazi ukuhlangabezana nokusetshenziswa kokugqoka okuphezulu, indawo eqinile yokugqwala, ikakhulukazi isici esivelele ukuphila kwenkonzo ende, isilinganiso salo samanani okusebenza singcono kakhulu kunamanye ama-valve ensimbi afanayo. Ngokuthuthuka okuqhubekayo kanye nenqubekelaphambili yesayensi nobuchwepheshe, izinto zokwakha ze-ceramic ezivela ekwakhiweni, ekubumbeni, ekucubunguleni nasekuhlanganiseni ubuchwepheshe kanye nezinye izici zobuchwepheshe zivuthiwe futhi ziphelele, i-valve ye-ceramic nokusebenza kwayo okuhle kakhulu ukuze kuqashelwe abantu embonini. . Okuhlangenwe nakho okuphumelelayo kokwenza ama-valve e-ceramic kungabuye kusetshenziswe emikhakheni yobunjiniyela ethuthuke kakhulu.
