Ukusetyenziswa kwevalve yebhabhathane enedayamitha enkulu kwiivalvu zamashishini

(1) Dibanisa ivalve ngomsonto. Olu xhulumaniso luqhele ukwenziwa ngoomatshini

I-ALVE INLET KUNYE NE-OUTLET IPHELA NGEMIBUPHO E-TAPERED OKANYE OKUQONDILE ENOKUQHAGAMSHELWA NE-TAPERED PIPE THREAD JOINTS OKANYE ILINE. Ngenxa yokuba kunokwenzeka ukuba kubekho iziteshi ezinkulu zokuvuza kolu nxibelelwano, 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 ebizwa ngokuba yi-50mm elandelayo. Ukuba ubukhulu bedayamitha bukhulu kakhulu, kunzima kakhulu ukuyifaka kunye nokutywina umdibaniso.
Ukuququzelela ukufakwa kunye nokususwa kwee-valve ezinentambo, iziqhagamshelo zifumaneka kwiindawo ezifanelekileyo kwi-piping system. Iivalvu ukuya kuthi ga kwi-50mm ngokobukhulu begama zingasebenzisa umkhono ohlangeneyo njengodibaniso, kunye nemisonto edibanisa iindawo ezimbini zejoyinti.
(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 kumbhobho.
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.
Kwidayamitha yegama likhulu, ukusetyenziswa kweemeko zokulayisha, ubushushu obuphezulu, umzimba wevalve uhlala uthatha i-groove welding, kwangaxeshanye, i-welding joint ineemfuno zokuqala, kufuneka ikhethe i-welder eyomeleleyo yobugcisa ukugqiba umsebenzi.
Ivalve yebhabhathane yokungenisa umoya enkulu ekusetyenzisweni kweevalvu zoshishino Okwangoku ilizwe lethu amashishini ahlukeneyo evalve yentsimbi, ivalve esetyenziswa kakhulu ekuveliseni ivalve yesinyithi esetyenziswa kumakhulu eminyaka yembali, ethe ngokuphuculwa kwesakhiwo kunye nezinto, kodwa Ukusikelwa umda, izinto zentsimbi ziya zisiba ninzi kwaye azikwazi ukuziqhelanisa neemeko zokusebenza ezimbi, ukunxitywa okuphezulu okunamandla kunye nomhlwa. 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 benzululwazi. Yinto entsha enesibindi kwaye enenzuzo ukuyifaka 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 iyanciphisa umda wokusetyenziswa kumashumi eminyaka akutshanje, ngenxa ye-martensitic isigaba senguqu yetekhnoloji yokuqina, isayensi yezinto ezidibeneyo kunye neteknoloji kunye nophuhliso kunye nenkqubela phambili yombono we-nanometer ceramics eyenziwe ngodongwe kunye ne-porcelain. "brittle" ine * * ukuphucula, ukuqina kunye nokomelela kuphuculwe kakhulu, kwandiswa uluhlu lwesicelo.
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 aphumeleleyo okwenza iivalvu ze-ceramic zinokusetyenziswa nakwiindawo zobunjineli eziphucukileyo.
