Ungayikhetha njani iqondo lobushushu eliphantsi lendawo yendawo yendalo?

UkukhethaI-valves yesangoIimeko zobushushu ezisezantsi kufuneka zithathwe ngokuqondakalayo kwimiba emithathu: ubunzima bezinto eziphathekayo, ukuSebenza okuSebenzayo, ngoyilo olulandelayo:

Ubunzima bezinto ezibonakalayo: Eyona nto iphambili kubushushu obungaphantsi

Kwimeko zobushushu eziphantsi, izixhobo zithambekele ekuphulukaneni nobunzima babo ngenxa "yokubuyisa amaqondo obushushu asezantsi", ekhokelela ekuqhekekeni iivalves zesango. Xa ukhetha, eyona nto iphambili kufuneka inikezwe kwizixhobo ngobunzima obugqwesileyo obuhle kakhulu:

I-carbon yentsimbi / intsimbi ephantsi ye-Allol: Ifanelekile i-Ponarios yobushushu kunye ne-Dea ePhakamileyo isuka -40 ℃ ukuya kwi-16mndr yovavanyo lwe-16mndr (i-Ak) ye-How -40 ℃ -40 ℃, enokuhlangabezana neemfuno zomsebenzi wemizi-mveliso.

Intsimbi engenasimo: Ifanelekile kwiimeko eziphantsi zeqondo lobushushu ezingezantsi -19 ℃ (i-airling ye-itrogen) kunye ne-Groight In-Paysiness (i-GORDINGS) kunye ne-GOORDE YEMIQATHANGO YOBUCHWEPHESHE, NOBUCHWEPHESHE.

I-Nickel Alloys Alloys, enjengeMoney Alloy (Nicel Allow Allow (i-CR FREY), ilungele iindawo ezinomsindo (-253), kungekho mngcipheko wokufumana amaqondo obushushu asezantsi.

Ukusebenza kokutywina: isiqinisekiso se-zero yokuvuza

Ukusebenza kokutywina kobushushu obuphantsiI-valves yesangoichaphazela ngokuthe ngqo ukhuseleko lwenkqubo, kwaye ifomu yokutywina kufuneka ikhethwe ngokweemeko zomsebenzi:

Ukutywina kwensimbi: intsimbi ihlanganiswe ngobhedu, i-Aluminiyam, okanye igrafu eguquguqukayo, ilungele i-oxysity ephezulu, kunye nokuthembeka kwe-oxygen ephantsi, ngentembeko ephezulu yokutywina.

Ukutywinwa kwentsimbi: i-Polytetrafluoroothyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyeyley (Ptfe, Ukunyangwa kobushushu -200 ℃ ~ 50 ℃ ~ Igrafu eguquguqukayo (Ukuchasana nobushushu -200 ℃ ~ 1650 ℃), kunye nokuxhathisa amaqondo obushushu kunye nobushushu obuphezulu, kufanelekile ukutshintsha iimeko eziphezulu kunye nezantsi.

I-Belbles yokutywina: I-Belli yentsimbi (ezinje ngentsimbi yama-316 i-stainess yentsimbi) inokufumana "i-zero yokuvuza" kwaye ilungele umsasazi onobushushu onobushushu, ngelixa unqanda unxibelelwano oluthile phakathi kwe-valve kunye nendawo yenkonzo.

Uyilo lolwakhiwo: Ulungelelwaniso lokulungelelanisa iimeko zokusebenza kweqondo lobushushu

Iqondo lokushisa eliphantsiI-valves yesangoKufuneka unciphise ilahleko ebandayo kwaye uphephe uxinzelelo loxinzelelo ngokusetyenziswa kolwakhiwo:

Isakhiwo eside sentamo: I-valve stem yamkela uyilo olude lwentamo (ngesiqhelo i-100-300mm ubude), enokuthintela ukuhanjiswa kwamaqondo avela kwi-rostbite ukuya kwi-rostbite ye-rostbite ukuya kwi-rostbite ye-rostbite kumgangatho ophantsi (ukunqanda ityhefu kunye nokugqwesa okuphakathi).

Ukuthintela iqabaka kunye nokufakelwa: i-faketer ye-inshurensi (njenge-polyurethane foam okanye i-rolly wobol) ingafakwa ngaphandle kwe-veli ye-valve ukunciphisa ukulahleka komthamo wokupholisa; Ezinye iivalva zesango ziyile "imingxunya yokuphefumla" yokukhupha ngokukhuselekileyo ukuvuza kwemithombo yeendlela ezinamafutha asezantsi kwaye kuthintele ukuqokelelwa kwe-prost kwitywina le-valve.

Uyilo lwe-Anti Goodmer Hammer: I-valve core kunye nendawo yokuhlalisa i-varve yoyilo lokunciphisa isando samanzi (i-valve enefuthe eliphantsi kwiqondo lokuhamba eliphantsi, kwaye isando lamanzi linokubangela i-upupture).
