Iindlela ezili-9 zokwandisa uBomi beNkonzo yeeVavu zeShishini

Jonga umfanekiso oMkhulu
Iivalvu zenziwa ukuba zihlale ixesha elide.Nangona kunjalo, kukho iimeko apho iivalve zamashishini azihlali ngendlela ebekufanele ukuba zihlale ngayo.Ukuchonga ezi meko kunokunceda ukwandisa ubomi bevalve.Ukongeza, ukugcinwa kwevalve yinto ebalulekileyo kuyo nayiphi na impilo yevalvu.

Ukunxitywa kunye nokukrazuka kwevalve yinto eqhelekileyo.Kodwa, ngokufakela okufanelekileyo kunye nokugcinwa, unokwandisa ixesha lakho lenkonzo yobomi.Izisombululo ze-band-aid azikho izisombululo ezinde xa kuziwa ekugcinweni kwevalvu.

Kukho iindlela ezininzi zokwandisa ubomi benkonzo yevalve, izinto ezintathu zihlala zidlala.Le yinkqubo yokhetho, inkqubo yokufakela kunye nenkqubo yokulondoloza.Ukukhetha uhlobo olululo lwesivalo ngundoqo kumjikelo wobomi bevalvu.Ezinye ezimbini zandisa ulindelo kubomi bevalve.

Eli nqaku lixubusha iindlela ezahlukeneyo zendlela yokwandisa ubomi benkonzo yeevalvu zoshishino.

#1 Qonda iiValves

Kukho iindidi ezininzi zeevalvu kumsebenzi nje omnye.Inyathelo lokuqala ekugcineni imfezeko yesivalo ukuze ukwazi ukwandisa ubomi bayo kukuqonda indlela isivalo esithile esisebenza ngayo.

Khangela ileyibhile ye-XHVAL kwivalve yakho ukuze wazi iinkcukacha zevalve, kubandakanywa nodidi lwesixokelelwano ekufuneka sisetyenziselwe ivalve ethile.Ukongezelela, hlala ufunda incwadana ehamba kunye nevalve ukwazi ukuba yeyiphi into eyenziwa yivalve, uxinzelelo kunye nomgangatho wokushisa kunye nezinto ezithandwayo.

Umzekelo, iivalve zebhola zisetyenziselwa kuphela ukuvalwa okuqinileyo.Ivalve yesango inomthamo wokuthokoza kodwa ithanda ukukhuhlana.Iivalve zebhabhathane zikhaphukhaphu kwaye zilungele ukwahlulwa kwemidiya kodwa kukho umkhwa wokuba isubstrates zihlale kwivalve.I-valve yokukhulula iya kuba yinto ekhethekileyo yokukhetha.

Inxalenye yokuqonda ivalve nganye kukwazi ukufakela kwayo ngokufanelekileyo.Yazi ukuba loluphi uhlobo lokubhoboza ekufuneka lusetyenziswe kwivalvu ukuba uxinzelelo luqwalaselwa kakhulu.Nokuba ivalve kufuneka ibhowuthwe, idityaniswe okanye izinto ezithandwayo nazo zizinto eziphambili.Oku kunokuthetha ukuvuza okunokwenzeka okanye ukutywinwa okuqinileyo.

Enye yeengxaki xa ungaqhelananga neendawo zevalvu, ungaphela uyonakalisa ivalve ngenxa yokungachongi kakuhle.Omnye umzekelo onjalo kukujika kweendawo zokumisa ukuhamba kwivalve kunye ne-actuator.Iindawo zokumisa ukuhamba zihlala zikhangeleka njengeebholiti kunye namantongomane.Ezi akufuneki zichukunyiswe njengoko ezi zigcina idiski ekujikelezeni.

Nangona kunjalo, ngokuzifundisa ukuba izakhi zevalvu zangaphandle zikhangeleka njani, kwaye ukwazi ukuba iindawo zevalvu zibekwe phi kunokukusindisa ekonakalisweni kweevalvu.

Iingqwalasela zobuchwephesha ezifana noxinzelelo, ulwalathiso lokuhamba, ubushushu, phakathi kwezinye, nazo ziyinxalenye yegophe lokufunda.Ukubala eyona ndawo isebenzayo (BEP) ikunika amaxabiso apho iivalvu zisebenza ngokugqibeleleyo.

#2 Qinisekisa uKhetho lweVavu eLungileyo

Ukukhetha i-valve kunokuba nzima.Kodwa, eli nqanaba linqanaba lokwenza okanye lokuqhawula.Ukuba ukhuphela inkqubo yokhetho, ungakhetha ivalve engafanelekanga.Oku kusenokuthetha ilahleko enokwenzeka.

Esinye sezizathu eziphambili zokuvuza kuyilo lwevalvu engalunganga okanye imathiriyeli ngokunxulumene namajelo eendaba.Ngexesha elide, i-valve engalunganga iya kulahlekelwa ukusebenza kwayo kakuhle.Oko kuya kuthetha ilahleko kuwe.

Into ekufuneka uyenzile kukwazi iimpendulo zale mibuzo:
1.Yintoni uhlobo lwamajelo eendaba?
2.Yintoni iqondo lokushisa kwimidiya?
3.Luluphi uhlobo loxinzelelo lwamajelo eendaba?
4.Ingaba ivalve iya kuba kwindawo evulekileyo okanye iya kuvalwa ngalo lonke ixesha?
Ukuthintela ukucatshulwa kwevalve engalunganga ngabavelisi bevalvu, hlala uphonononga iinkcukacha zevalvu kwaye usoloko ubuza imibuzo elungileyo.

#3 Qinisekisa uFakelo olululo

Ufakelo olufanelekileyo luqala ekugcinweni kweevalve emva kokuba ezi zihanjiswe.Iivalvu zinokufumana umonakalo obangelwa kukungakhathali, ngakumbi xa iivalve zishiywe zingagqunywanga kwizinto.

Omnye umba oqhelekileyo phakathi kweengcali zevalve kukususwa kwee-end caps ezisebenza njengokhuselo lweendawo zangaphakathi zevalve.Xa ezi zisusiwe, amathuba okuba, imizimba yangaphandle inokungena ngaphakathi kwevalve.Oku kunokubangela umonakalo kwizihlalo xa isivalo sisebenza.Nje ukuba izihlalo zonakele, kukho amandla aphezulu okuvuza.

Ukongezelela, i-valve kufuneka ihlolwe ngokucokisekileyo ngaphambi kokuba ifakwe kwisistim.Oku kukuqinisekisa ukuba umzimba kunye namacandelo awonakaliswa ngexesha lokuthunyelwa.

#5 Bacoce

Ukuze iivalvu zihlale ixesha elide, kunyanzelekile ukuba ezi kufuneka zicocwe ubuncinane kanye ngonyaka okanye ukuba kuyimfuneko, ngakumbi xa indawo yesityalo imdaka.Sebenzisa izixhobo ezifanelekileyo ezifana nelaphu, i-lubricant okanye iibrashi zocingo ukucoca umzimba wevalvu kunye namalungu afana nemisonto yesikhondo, iziqobo, amandongomane kunye nezinto ezinje.

Kwakhona kubalulekile ukuba iivalve zihlanjululwe ngokufanelekileyo ngaphambi kokuba zifakwe kwinkqubo yombhobho.Ngale ndlela, iivalvu aziqulathi izinto ezingcolisayo ezinokuthi zonakalise kungekuphela nje ivalve kodwa kwanemithombo yeendaba enokuhamba kuyo.

#6 Banxibe

Kwezinye izicelo eziqulethe imidiya ebolileyo okanye ezo zicelo ezifuna uxinzelelo oluphezulu kunye nobushushu, ukugquma iivalvu ngeengubo zokufudumala kunokunyusa inkonzo yokuphila kweevalve.Iingubo zokwaleka ezishushu kufuneka zisebenzise inkqubo ye-oxy-fuel yesantya esiphezulu njengoko ezi zibonakaliswe ukuba zinkulu ekugqumeni iivalvu.

#7 Ukuhlolwa rhoqo

Enyanisweni, iivalve kufuneka zihlolwe rhoqo.Nangona lo msebenzi unokuba yindinisa, uyimfuneko.Kwiivalvu zebhola kunye nezinye iivalve ezinxulumeneyo, ngokwenza njalo, uqinisekisa ukuba iivalve azinamonakalo kwaye zigcina ukuvalwa okuqinileyo.Iivalvu ezithokozayo zifuna uqwalaselo lomonakalo wokukhuhlana

Njengomthetho wesithupha, iivalvu ezisetyenziswa ngamandla kufuneka zitshintshwe zingaphelanga iinyanga ezintandathu zokusetyenziswa.Nangona kunjalo, kwizicelo ezinzima, iivalve kufuneka zihlolwe rhoqo kwiinyanga ezintathu.Ukuhlolwa okunjalo kufuneka kubandakanye ukujonga iindawo ezivuzayo, ukubola kunye neendawo ezineziphene.

Ngexesha lokuhlolwa rhoqo uya kufumana iintanda, ukusikwa kunye nokuvuza kwivalve.Ezo ziganeko ziqhelekile xa iivalvu zisetyenziswa rhoqo ekuhambeni kwexesha.

#8 ULondolozo oluThintelayo

Ukuba iivalvu azikwazi ukumelana nomhlwa, sebenzisa iimveliso ezinokuthi zithintele ukuqala komhlwa okunokuthi konakalise ivalve.Usetyenziso olulula lwenyanga lwe-lubricant yenjongo ngokubanzi lunokwenza imimangaliso kwaye lunokunyusa ubude bobomi bevalvu.Nangona kunjalo, qaphela isithambiso esinokusetyenziswa njengoko kucetyisiwe ngabavelisi beevalvu.

Ukongezelela, ukugcinwa kokukhusela kufuneka kuqale ngokuqinisekisa ukuba izinto ezisetyenziselwa ukwenza i-valve kufuneka zihambelane nephepha lenkcazo enikezelwe ngumsebenzisi wokugqibela.Kwakhona, njengenxalenye yokugcinwa kokukhusela kukuqinisekisa ukuba iivalve zihlala zigcoba.

Kufuneka kubekho iimvavanyo eziqhutywa rhoqo ukwenzela ukuba kubonwe kwangethuba ukuvuza okunokwenzeka kunye nezinto ezithandwayo.Ngelixa oku kunokubonwa njengomzamo oneendleko ezinkulu, enye yeendlela ezilungileyo zokwandisa ixesha lokuphila kweevalvu zemizi-mveliso kukuqhuba iimvavanyo zokuvuza.

#9 Field Machining

Xa iivalve zisetyenziswa ngokuphindaphindiweyo, amandla okutywina oqhagamshelwano ayaphela.Ukuqinisekisa ukuba iivalve azivuzi kwiiflange ngaphandle kokususa ivalve kwisixokelelwano, kusetyenziswa umatshini wentsimi.

Isishwankathelo

Ngokufunda uhlobo lwevalve ethile, ukucoca i-valve kunye nokuqhuba ukugcinwa kokukhusela, phakathi kwabanye, kunokunyusa ubomi beevalve zoshishino.Ukuba unqwenela ukufunda ngakumbi malunga neevalvu zemizi-mveliso, zive ukhululekile ukuqhagamshelana nathi.
