Ivalve yebhola elintantayo
Yini i-valve yebhola entantayo?
A Ivalve yebhola elintantayoisebenzisa ibhola elizungezayo kanye nesiqu esihlinzeka ngokuvula/ukuvala ukugeleza.
Ii-valve yebhola elintantayosebenzisa ukucindezela komugqa wemvelo ukuze ucindezele futhi uvale ibhola esihlalweni esingezansi komfula.Ukucindezela komugqa kuvezwa endaweni enkulu - ubuso bonke obuphezulu bebhola, okuyindawo elingana nosayizi wepayipi langempela.
A i-valve yebhola elintantayoiyivalvu enebhola elintantayo (elingagxiliwe yi-trunnion) ngaphakathi komzimba we-valve, ikhukhuleka iye ohlangothini olungezansi lomfula bese isunduza ngokuqinile esihlalweni ngaphansi kwengcindezi ephakathi ukuze iqinisekise ukwethembeka kokuvala.I-valve yebhola elintantayo inesakhiwo esilula, ukusebenza kahle kokuvala kodwa impahla yesihlalo iyadingeka ukuze imelane nomsebenzi njengoba ingcindezi yokuvala ivalwe yindandatho yesihlalo.Ngenxa yokungatholakali kwezinto ezisezingeni eliphezulu, i-valve yebhola elintantayo isetshenziswa kakhulu phakathi nokufakwa kwengcindezi ephansi.
Lapho i-valve ibekwe lapho ibhore iqondaniswe khona ngendlela efanayo nepayipi, isendaweni evulekile, futhi uketshezi lungadlula phansi komfula.I-NORTECHI-valve yebhola entantayo umkhiqizo omusha okhiqizwa ukuguqulwa kwe-valve evamile kanye nokwamukelwa kwezinga lamazwe ngamazwe lakamuva.
Izici eziyinhloko ze-valve yebhola entantayo ye-NORTECH?
1. Umklamo Wezihlalo Ezikhethekile
samukela umklamo wesakhiwo sendandatho yophawu oluguquguqukayo yevalve yebhola elintantayo.Uma umfutho ophakathi nendawo uphansi, indawo yokuxhumana yendandatho yophawu nebhola incane.Izonciphisa ukungqubuzana kanye ne-torque yokusebenza futhi iqinisekise ukucinana ngesikhathi esifanayo.Lapho ukucindezela okuphakathi kukhushulwa, indawo yokuxhumana yendandatho yophawu nebhola iba nkulu kanye nokuguqulwa okunwebekayo kwendandatho yophawu, ukuze indandatho yophawu ibekezelele indawo ephakeme. umthelela ngaphandle kokulimala.

2. Idizayini Yesakhiwo Sokuvikela Umlilo
Esimweni somlilo ngesikhathi kusetshenziswa ivalvu, iringi yesihlalo eyenziwe nge-PTFE Noma ezinye izinto ezingezona ezensimbi zizobola noma zonakaliswe ngaphansi kwezinga lokushisa eliphezulu futhi kuzoholela ekuvuzeni okukhulu koketshezi, kuyingozi impela endaweni evuthayo noma eqhumayo. Indandatho yophawu olungashi ibekwe phakathi kwebhola nesihlalo ukuze emva kokushiswa kwesihlalo se-valve, okuphakathi kuzophusha ibhola ngokushesha libheke ezansi nendandatho yensimbi yophawu lwensimbi ukuze yakhe insimbi eyinsimbi esakhiweni sokuvala sensimbi esingalawula ngempumelelo ukuvuza kwe-valve. ngaphezu kwalokho, i-gasket evala i-flange ephakathi, engaqinisekisa ukuvala ngisho nangaphansi kwezinga lokushisa eliphezulu .Umklamo wesakhiwo ongashi wevalvu yebhola elintantayo uhambisana nezidingo eziku-APl607, APl6FA, BS 6755 namanye amazinga.
Idizayini Yesakhiwo Sokuvikela Umlilo we-flange ephakathi
Idizayini yesakhiwo esingashisi umlilo (ngemuva kokushiswa)
Idizayini Yesakhiwo Sesihlalo Sokungashi
Idizayini yesakhiwo esingashisi umlilo (ukusetshenziswa okuvamile)
3. Isakhiwo Sokungaguquguquki
I-valve yebhola iklanywe ngesakhiwo esingaguquki kanye nedivaysi yokukhipha ugesi omile ukuze yakhe ishaneli emile phakathi kwebhola nomzimba ngesiqu ukuze ikhiphe ugesi ongashintshi okhiqizwa ukungqubuzana kwebhola nesihlalo, ukugwema umlilo noma ukuqhuma. okungase kubangelwe ukucwazimula okumile kanye nokuqinisekisa ukuphepha kwesistimu.

4. Ukuvalwa Okuthembekile Kwesiqu Se-Valve
Isiqu siklanywe ngehlombe ngaphansi kwalo ukuze lokho kungeke kushaywe yi-medium ngisho nangaphansi kwesimo esibi kakhulu njengokukhuphuka kwengcindezi engavamile ngaphakathi kwe-valve cavity, ukwehluleka kwepuleti le-gland nokunye Ngaphezu kwalokho, ukugwema ukuvuza ngemva kwalokho. ukupakishwa kwe-stem kuyasha uma kuba nomlilo, i-thrust bear ibekwe endaweni lapho ihlombe le-stem kanye nokuthintana nomzimba ukuze kwakheke isihlalo sokuvala uphawu.Amandla okuvalwa kwesigxivizo esibuyela emuva azokwenyuka ngokwenyuka kwengcindezi ephakathi nendawo, ukuze kuqinisekiswe ukuvalwa kwesiqu okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjwe ukuvuza futhi kugweme ukusabalala kwengozi. Isakhiwo sokupakisha sohlobo lwe-V senzelwe isiqu, uhlobo lwe-V ukupakisha kungashintsha ngempumelelo amandla okucindezela kanye namandla aphakathi kwe-gland ibe amandla okuvala isiqu.Ngokwezidingo zabasebenzisi, indlela yokucindezela yokupakisha elayishiwe ye-disc ingamukelwa ukwenza ukubekwa uphawu kokupakishwa kwesiqu kuthembeke kakhudlwana.
Isiqu esifakwe phansi ngeke siqhunyiswe ngaphansi kwengcindezi ephakathi nendawo
Isiqu esifakwe phezulu singase siphume ngaphansi kwengcindezi emaphakathi

5. Ukuvimbela Ukukhiya kanye Nokusebenzisa Kabi
I-valve yebhola yamanuwali ingakhiywa ngelokhi endaweni evulekile egcwele noma evala ngokugcwele.Isiqephu sokuma esivulekile esingu-90° esivulekile nesivalekile esinembobo yokukhiya siklanyelwe ukugwema ukusebenzisa kabi ama-valve okubangelwa ama-opreator angagunyaziwe, futhi singavimbela ukuvuleka noma ukuvala kwamavalvu, noma ezinye izingozi ezibangelwa ukudlidliza kwepayipi noma izici ezingalindelekile.Isebenza kahle kakhulu ikakhulukazi kuwoyela ovuthayo naqhumayo, amapayipi asebenza ngamakhemikhali nawezokwelapha noma amashubhu asensimini.Ingxenye esekhanda lesiqu efakwe nesibambo yamukela umklamo oyisicaba.Lapho ivalvu ivulwa khona, isibambo sihambisana nepayipi, futhi izinkomba zokuvala zevalvu ziqinisekisiwe ukuthi zilungile.
