Ukusetyenziswa kwevalve yebhabhathane enedayamitha enkulu kwiivalvu zamashishini

Ukufakwa kwevalve yebhabhathane engenisa umoya kwidayamitha enkulu (1) Qhagamshela ivalve ngomsonto. Olu Qhagamshelwano luQHELEKILE NGOKUCHUKUTHELA I-ALVE INLET KUNYE NENDAWO YOKUPHUMA IPHELA KWI-TAPERED OKANYE OKWENZIWA KWEMICHA ENGQINISEKILEYO ENOKUQHAGAMSHELWA KWI-TAPERED PIPE JOINTS OKANYE ILINE. Ngenxa yokuba kunokwenzeka ukuba kubekho iziteshi ezinkulu zokuvuza kolu qhagamshelwano, ezi ziteshi zinokuvaleka nge-sealant, iteyipu yokutywina, okanye ukupakisha. Ukuba izinto ze-valve yomzimba zinokudityaniswa, kodwa i-coefficient yokwandiswa ihluke kakhulu, okanye uluhlu lweenguqu zeqondo lokushisa likhulu, uxhulumaniso oludibeneyo kufuneka lube yi-honey sealed welding. Uqhagamshelo olunemisonto lwevalvu ubukhulu becala yimeridian eqhelekileyo kule valve iyi-50mm ilandelayo. Ukuba ubukhulu bedayamitha bukhulu kakhulu, kunzima kakhulu ukuyifaka kunye nokutywina umdibaniso. Ukuququzelela ukufakwa kunye nokususwa kwee-valve ezinentambo, iziqhagamshelo zifumaneka kwiindawo ezifanelekileyo kwinkqubo yokubhobhoza. Iivalvu ukuya kuthi ga kwi-50mm ngokobukhulu begama zingasebenzisa umkhono ohlangeneyo njengendibaniselwano, enemisonto edibanisa la malungu mabini. (2) Ivalve yokudibanisa iFlange. Iivalve eziphothiweyo kulula ukuzifaka nokususa. Kodwa zinkulu kuneevalvu ezithungelweyo, kwaye ngokuhambelanayo zibiza kakhulu. Ngoko ke, ifanelekile ukudibanisa kombhobho yobukhulu obuhlukeneyo kunye noxinzelelo. Nangona kunjalo, xa ubushushu budlula ama-350 degrees, ngenxa yokukhulula iibholithi, iigaskets kunye neeflanges, ezinciphisa kakhulu umthwalo kwiibholithi, ukuvuza kunokuthi kwenzeke kunxibelelwano lweflange olugxininiswe kakhulu. (3) Weld ivalve. Olu xhulumaniso lufanelekile kuzo zonke iintlobo zoxinzelelo kunye nobushushu, kwaye luthembeke ngakumbi kunoxhumo lwe-flanged xa lusetyenziswe phantsi kweemeko ezinzima. Kodwa i-valve edibeneyo i-disassembly kunye nokufakwa kwakhona kunzima, ngoko ke ukusetyenziswa kwayo kunqunyelwe ngokuqhelekileyo kunokuqhuba ngokuthembekileyo ixesha elide, okanye ukusebenzisa iimeko zokulayisha, iimeko zokushisa okuphezulu. Njengesikhululo samandla e-thermal, iprojekthi yamandla enyukliya, iprojekthi ye-ethylene ekumbhobho. Iivalve ezidityanisiweyo ezineedamitha ezibizwa ngokuba yi-50mm zihlala zineejekhi ezidityanisiweyo zokubamba umbhobho ekupheleni komthwalo. Ngenxa yokuba i-socket welding yenza i-gap phakathi kwe-socket kunye nombhobho, onokubangela ukuba i-gap ihlanjululwe ngamanye amajelo, kwaye ukungcangcazela kombhobho kuya kwenza inxalenye edibeneyo idinwe, ngoko ke ukusetyenziswa kwe-socket welding kulinganiselwe. Kwi-diameter yegama likhulu, ukusetyenziswa kweemeko zokulayisha, ubushushu obuphezulu, umzimba wevalve uhlala uthatha ukuwelda kwe-groove, kwangaxeshanye, i-welding joint ineemfuno zokuqala, kufuneka ikhethe i-welder eyomeleleyo yobugcisa ukugqibezela umsebenzi. Ivalve yebhabhathane ekusetyenzisweni kweevalvu zoshishino Okwangoku ilizwe lethu amashishini ahlukeneyo evalve yesinyithi, ivalve esetyenziswa kakhulu ekuveliseni ivalve yesinyithi esetyenziswa kumakhulu eminyaka yembali, ethe ngokuphuculwa kwesakhiwo kunye nezinto eziphathekayo, kodwa ngokulinganiselwa kwayo, izinto zetsimbi ziya zisiba ninzi kwaye azikwazi ukuziqhelanisa neemeko zokusebenza ezimbi, ukunxitywa okuphezulu okunamandla kunye nokugqwala. Ikakhulu ibonakaliswe kubomi obufutshane benkonzo, ukuvuza kuchaphazele kakhulu uzinzo lwenkqubo yokusebenza. Ivalve yentsimbi yesiko ikwimfuno engxamisekileyo yokwenziwa ngokutsha kwezinto, uyilo kunye nenkqubo yokuvelisa. Okwangoku, i-valve esetyenziswa ngokuqhelekileyo kwimveliso yamashishini ahlukeneyo kwilizwe lethu i-valve yensimbi. Ukusetyenziswa kwevalve yentsimbi sele kudlule iminyaka eyikhulu yembali. Nangona iphuculwe ngesakhiwo kunye nezinto eziphathekayo, ayikwazi ukuhlangabezana neemfuno zokugqoka okuphezulu, ukubola okunamandla kunye nezinye iimeko zokusebenza ezinzima. Ikakhulu ibonakaliswe kubomi obufutshane benkonzo, ukuvuza kuchaphazele kakhulu uzinzo lwenkqubo yokusebenza. Ivalve yentsimbi yesiko ikwimfuno engxamisekileyo yokwenziwa ngokutsha kwezinto, uyilo kunye nenkqubo yokuvelisa. Imathiriyeli ye-ceramic ephucukileyo, njengesixhobo esitsha kwinkulungwane yama-21, ithathelwe ingqalelo ngabasebenzi abaninzi bezenzululwazi. Yinto entsha enesibindi kunye nenzuzo yokuyisebenzisa kwiivalvu zoshishino. Izixhobo zeCeramic zinoguquko oluncinci kakhulu kwaye zinamandla okubopha aphezulu kuneentsimbi. Ngokuqhelekileyo, i-crystalline ionic radius yezinto ze-ceramic incinci, kwaye ixabiso lombane we-ionic liphezulu, kwaye inani lokulungelelanisa likhulu. Ezi zakhiwo zimisela amandla okuqina, amandla acinezelayo, imodyuli elastiki kunye nokuqina kwezixhobo ze-ceramic ziphezulu kakhulu. I-Ceramic ngokwayo, nangona kunjalo, "i-brittle" kunye ne-processing enzima imida yokusetyenziswa kwayo kumashumi eminyaka akutshanje, ngenxa ye-martensitic isigaba senguqu yeteknoloji yokuqina, isayensi yezinto ezihlanganisiweyo kunye nobuchwepheshe kunye nophuhliso kunye nenkqubela phambili yombono we-nanometer ceramics eyenziwe ngodongwe kunye ne-porcelain. "brittle" ifumene * * ukuphucula, ukuqina kunye nokomelela kuphuculwe kakhulu, kwandiswa uluhlu lwezicelo. Ivalve ye-ceramic enganyangekiyo isetyenziswa ikakhulu kumandla ombane, i-petroleum, ishishini lemichiza, isinyithi, imigodi, ukucocwa kwamanzi amdaka kunye nezinye iindawo zoshishino, ngakumbi xa kujongwe ukunxiba okuphezulu, ukubola okuqinileyo, ubushushu obuphezulu, uxinzelelo oluphezulu kunye nezinye iimeko ezinzima zokusebenza, kodwa ikwabonisa ukusebenza kwayo kakuhle. Inokuhlangabezana nokusetyenziswa kokunxiba okuphezulu, indawo eyomeleleyo ye-corrosion, ngakumbi into ebalaseleyo bubomi benkonzo ende, umlinganiselo wexabiso lentsebenzo ungcono kakhulu kunezinye iivalvu zetsimbi ezifanayo. Ngophuhliso oluqhubekayo kunye nenkqubela phambili yenzululwazi kunye nobuchwepheshe, izinto ze-ceramic ezivela kuqulunqo, ukubumba, ukusetyenzwa kunye nokudibanisa iteknoloji kunye neminye imiba yeteknoloji ikhulile kwaye iphelele, ivalve ye-ceramic kunye nokusebenza kwayo okugqwesileyo ukufumana ukuqondwa kwabantu kwishishini. . Amava ayimpumelelo okwenza iivalvu ze-ceramic nazo zinokusetyenziswa kwiindawo zobunjineli eziphucukileyo.
