Incazelo lephelele yendlela lefanele yekusebenta kwevalve

Kulungiselela ngaphambi kwekusebenta

Ngaphambi kwekutsi usebentise i-valve, kufanele ufundze kahle ticondziso tekusebenta. Ngaphambi kwekusebenta, kumele ucace mayelana nekugeleza kwesicondziso segesi, kufanele unake kuhlola timphawu tekuvula nekuvala kwevalve. Hlola kubukeka kwe valve kutsi le valve imanti yini, uma kunemswakama lotawuba kwelashwa kwekomisa; uma kutfolakala kutsi kunetinye tinkinga letifanele kutsi kubhekanwe nato ngesikhatsi lesifanele, angeke tisebente ngekwehluleka. Uma ngabe i-valve legezi ingasebenti tinyanga letingetulu kwa-3, i-clutch kumele ihlolwe ngaphambi kwekucala, yenta siciniseko kutsi sibambo sisesimeni sesandla, bese uhlola insulation, steering kanye netintambo tagezi temoto.

Kusebenta Kahle Kwemavalvu Labhalwe Ngesandla

Emavalvu lasebenta ngesandla ngiwo lasetjentiswa kakhulu, futsi emasondvo abo esandla noma tibambo takhiwe ngekuhambisana nemandla ebantfu lavamile, kucatshangelwa emandla endzawo yekuvala kanye nemandla ladzingekako ekuvala. Ngako-ke, angeke ukhone kusebentisa lever lendze noma sandla lesidze kuhambisa ipuleti. Labanye bantfu bajwayele kusetjentiswa kwesandla sepuleti, kufanele banake kakhulu kuvulwa kwevalve kufanele kusetjentiswe kuphocelela busheleleti, kugwema emandla kakhulu, lokuholela ekuvuleni nekuvalwa kwevalve, emandla kufanele abe busheleleti, hhayi umtselela. Lomunye umtselela kuvulwa kanye nekuvalwa kwetincenye tevalve lesetulu-umfutfo bekutsatfwa njengalomtselela kanye nemavalvu jikelele angeke alingane neGang.

Lapho valve ivulekile ngokugcwele, i-handwheel kufanele inverted kancane, kute imicu emkhatsini tight, kute ungakhululi umonakalo. Kutsiemavalvu esango lekhuphukako,kukhumbula lokuvulekile ngalokuphelele futsi lokuvaliwe ngalokuphelele lapho sikhundla sesicu, kugwema kuvuleka ngalokuphelele lapho umtselela esikhungwini lesifile. Futsi kulula kuhlola kutsi kuvamile yini uma kuvalwe ngalokuphelele. Uma lihhovisi le valve livaliwe, noma sivalo se spool lesifakwe emkhatsini wemfucumfucu lomkhulu, indzawo yesicu levaliwe ngalokuphelele kumele ishintjwe. Kulimala kwendzawo yekuvala ivalvi noma isondo lesandla levalvi.

Luphawu lwevalve levulekile: valve yebhola,Ivalvu levivane lesemkhatsini, plug valve sicu phezulu ebusweni groove parallel isiteshi, kukhombisa kutsi valve esimeni evulekile ngokugcwele; lapho sicu sevalve sijikeleta nga 90 ° ngasencele noma ngasekudla, le groove imile emseleni, lokukhombisa kutsi le valve isesimeni lesivaliwe ngalokuphelele. Lamanye emavalvu ebhola, emavalvu ebutterfly, emavalvu epulagi ku-wrench kanye nesiteshi lesihambisanako sekuvula, lesimile sekuvala. Emavalvu lanetindlela letintsatfu, letine kumele asebente ngekuhambisana nekumaka kwekuvula, kuvala kanye nekubuyela emuva. Ngemuva kwekutsi umsebenti sewuphelile, sibambo lesinyakatako kufanele sisuswe.

Kusebenta kahle kwemavalvu ekuhlola

Kute kugwenywe emandla lamakhulu emtselela lakhiwa ngesikhatsi sekuvalwa kwe .ivalve yekuhlola lehleti ngerabha, le valve kumele ivalwe ngekushesha, ngaleyondlela kuvikeleke kwakheka kwekushesha lokukhulu kwekubuya emuva, lokuyimbangela yekucindzeteleka kwemtselela lokwakhiwako uma le valve ivalwa ngekushesha. Ngakoke, sivinini sekuvala se valve kumele sihambisane kahle nesilinganiso sekubola kwemkhakha lowehlako.

Uma lizinga lekugeleta lesemkhatsini lihlukahluka ngetulu kweluhlu lolukhulu, lizinga lelincane lekugeleta alikeneli kuphocelela lentfo yekuvala kutsi ime ngalokucinile. Kulesi simo, kuhamba element kuvala kungaba damped ngaphakathi uhla ethile stroke yayo. Kudvudvuta lokusheshako kwentfo levalako kungenta kutsi tincenye letihambako tevalve tiguge ngekushesha kakhulu, lokuholela ekuhlulekeni kwevalve ngaphambi kwesikhatsi. Uma ngabe lendzawo lesemkhatsini ishaya, kudvudvuta lokusheshako kwentfo levalako nako kubangelwa kuphazamiseka lokusemkhatsini lokukhulu. Noma ngukuphi lapho khona loku kunjalo, emavalvu ekuhlola kumele abekwe lapho khona kuphazamiseka lokusemkhatsini kuncishiswa khona.
