Indlela yokukhetha iivalve ezinamaqondo obushushu ahlukeneyo?

Ukuba i-valve kufuneka ikhethwe kwiimeko eziphezulu zokushisa, izinto eziphathekayo kufuneka zikhethwe ngokufanelekileyo. Izixhobo zeevalve ziya kukwazi ukumelana neemeko eziphezulu zokushisa kwaye zihlale zizinzile phantsi kwesakhiwo esifanayo. Iivalvu kumaqondo obushushu aphezulu kufuneka zibe zolwakhiwo oluqinileyo. Ezi zixhobo zinokuba yintsimbi esemgangathweni ephezulu kunye nentsimbi ephindwe kabini. Izinto ezisemgangathweni eziphantsi eziza kuchaphazela ukudibanisa kweqondo lokushisa aziyi kusetyenziswa, ngaphandle koko i-deformation okanye i-valve ye-creep material iya kuphetshwa.

Iimeko eziphezulu zobushushu

Iivalve zebhabhathane ze-Throttle zinokuzinza phantsi kobushushu obuphezulu. Ulwakhiwo kunyeumzimba wevalveiya kuqwalaselwa kunye neradiyetha ukuze ilungiswe ngezinto zokubeka ubushushu. Ukuba i-valve iqwalaselwa, izinto eziphathekayo ze-valve azinzile. Ukuba iqondo lokushisa lidlula umda onokuthi ivalve ikwazi ukumelana nayo, ayiyi kufaneleka kwivalve yakho.

Kufuneka uqwalasele iivalvu ezinemibhobho yeceramic okanye iivalvu ezineebhatyi zokupholisa ukulungelelanisa iziphumo zeemeko zobushushu. Ezi bhatyi zokupholisa zisebenza ngokujikeleza kwamanzi abandayo. Ngoko ke, izinto eziphathekayokwivalveiya kulungelelaniswa ngaphandle koxinzelelo oluphezulu lomda.

Iimeko zobushushu obuphantsi

Ukuba iqondo lobushushu lisezantsi kakhulu, njenge-29, i-valve ene-coefficient yokumelana nobushushu obuphantsi kufuneka ikhethwe. Kuluhlu lweqondo lokushisa eliphantsi kakhulu - 29 ukuya - 196 degrees celsius, iqokobhe kunye nezixhobo zetrim zinokuqina okwaneleyo ukugcina ubushushu kunye nokulinganisa iziphumo zamaqondo obushushu aphantsi kakhulu.

Kule meko yokushisa ephantsi, kufuneka ukhethe i-valve enezinto zokuzalisa kunye necandelo letanki yamanzi ukulawula imfuno yokushisa. Ukukhethwa kwezi valve kwenza ukuba iimeko zokushisa zigcinwe ngaphezu kwe-0.

Izilumkiso kumaqondo obushushu ahlukeneyo

Kukho imo enye ngaphandle kumanyathelo okhuseleko lwevalvu. Xa ivalve ivaliwe, olunye ulwelo kwigumbi levalvu luya kuhlala luvaliwe. Njengoko ixesha lihamba, olunye ulwelo luya kuhlala kwigumbi levalvu. Ngoko ke, ubushushu buya kuthatyathwa kancinci yi-atmosfera kwaye buphinde bufikelele kwiimeko zokushisa ezifanayo, okanye buphuphe kwigumbi levalve.

Xa oku kusenzeka, umthamo uya kunyuka ngamaxesha angama-600, okuya kuzisa uxinzelelo olumangalisayo kumzimba wevalvu. Olu xinzelelo luphezulu okanye uxinzelelo kumzimba wevalve lubizwa ngokuba lixabiso loxinzelelo olungaqhelekanga. Le meko ayilawuleki, ngoko inokubangela iingxaki ezinzulu zevalve kwaye inokuba ngunobangela wengozi.

Ukuze ugweme la mava angathandekiyo e-valve phantsi kweemeko ezininzi zokushisa, kufuneka ukhethe i-valve ene-orifice echanekileyo. Olu hlobo lwevalve ludla ngokusetyenziswa kule meko, kwaye le ndlela isetyenziswa kakhulu kule ntsimi.

imfuneko yokusebenza

Okokuqala, kufuneka uchaze zonke iimfuno zeqondo lokushisa kunye noxinzelelo lwemeko. Kufuneka ukhankanye uluhlu lobushushu kunye noxinzelelo lwevalvu ofuna ukuyisebenzisa. Kuya kukunceda ukhethe i-valve yezinto ezifanelekileyo ezifanelekileyo kumaqondo okushisa ahlukeneyo. Masithi ufuna ukusebenzisa le valve kubushushu obuphezulu. Kule meko, kucetyiswa ukuba kusetyenziswe i-valve yensimbi kuba inokumelana neemeko eziphezulu zokushisa ngaphezu kwayo nayiphi na enye into. Ukuba igesi okanye uxinzelelo lwe-liquid kwivalve luphezulu kakhulu, banokumelana ngokulula noxinzelelo.

Ukwengeza,khetha iivalvungenkqubo eyomeleleyo yokuthintela umva, ngakumbi xa isetyenziswa kumaqondo obushushu aphezulu.

isiphelo

Kukho iintlobo ezininzi zeevalvu kwimarike, kunye nokukhetha okuhlukeneyo phantsi kweemeko ezahlukeneyo zokushisa. Kufuneka uchaze iimfuno zakho kunye noluhlu lobushushu lwevalvu oza kusetyenziswa. Emva koko khetha ivalve ehlangabezana nemigangatho kunye neemeko kwaye ihlangabezana nazo zonke iimfuno zakho. Amanqaku alandelayo kunye neengcebiso kufuneka ziqwalaselwe ngaphambi kokukhetha iivalve phantsi kweemeko ezahlukeneyo zokushisa.
