IValve yokuhanjiswa kweNtsebenzo ePhezulu ye-K15 yePump ye-Diesel ye-Injini yokuTofwa iZahlulo eziSipareleyo ze-ISUZU KUBOTA ISEKI

1. Ubume bevalve yokuhambisa

(1) Ivalve yokuhambisa ioyile kunye nesitulo sevalve zizinto ezichanekileyo, ezenziwe ngentsimbi yealloy ephezulu. Imingxuma yabo yesikhokelo, ubuso obuphezulu kunye nezantsi ekupheleni kunye nemingxuma yezihlalo zicutshungulwe ngokuchanekileyo kwaye ziphantsi, kwaye azikwazi ukutshintshwa emva kokubhanqa.

(2) Inxalenye yekhowuni yevalve yokuphuma kweoyile yindawo etywinayo yecone yomphezulu wevalve. Inxalenye yekhowuni yevalve isilayidi kumngxuma wesikhokelo kwaye idlala indima ekhokelayo. Umsila wenziwa ngoomatshini ukwenza i-cross-section ukuvumela amafutha ukuba adlule. Umphezulu wecylindrical kumbindi wevalve yokuhanjiswa kweoyile ubizwa ngokuba ngummandla woxinzelelo, owenza umthamo woxinzelelo kunye nomphezulu wecone yokutywina.

(3) Umphezulu wesiphelo esisezantsi sesihlalo sevalve kunye nomphezulu wesiphelo somkhono weplunger wenziwa ngokuchanekileyo kwaye ufakwe ngokuqinileyo. Ziyaqiniswa yi-nut yoxinzelelo kunye ne-torque ecacisiweyo yokuqinisa. Kukho iwasha yobhedu yokutywina enoxinzelelo oluphezulu yobunzima obuthile phakathi kwentongomane yokucinezela kunye nesitulo sevalvu. Kukwakho negasket yokutywina enoxinzelelo oluphantsi phakathi kwentonga yokucinezela ivalve yokuhambisa ioyile kunye nobuso obuphezulu bendlu.

(4) Isikhongozeli sokunciphisa esisikiweyo sifakwe kumgodi ongaphakathi wevalve yokuhambisa i-oyile yokuhambisa i-oyile ukunciphisa umthamo wesithuba somngxuma ongaphakathi, ukukhuthaza ukumiswa kwesitofu ngokukhawuleza, kunye nokunciphisa ukunyuswa okuphezulu kwevalve yokukhupha ioyile.

2. Umsebenzi wevalve yokuhambisa

(1) Thintela ukuthontsiza kwe-oyile phambi kokutofa kunye nokunyusa isantya sokutofa: Xa impompo yokutofa i-oyile ibonelela ngeoyile, emva kokuba uxinzelelo lwe-oyile luphezulu kumandla okulayisha kwangaphambili omthombo wevalvu yokuhambisa ioyile kunye noxinzelelo olushiyekileyo kumbhobho weoyile woxinzelelo oluphezulu, ivalve yokukhupha ioyile Ivalve ye-oyile iyanyuka kwaye ikhowuni yokutywina ishiya isihlalo sevalve. Kuyimfuneko ukulinda de ibhande lokunciphisa uxinzelelo kwi-valve yokuhambisa i-oyile lishiye ngokupheleleyo umngxuma wesikhokelo sesihlalo se-valve ngaphambi kokuba i-fuel kwigumbi le-oyile yepompo ingangena kumbhobho we-oyile ophezulu.

(2) Thintela ukuthontsiza kweoyile emva kokutofa kunye nokunyusa isantya sokuvala: Xa unikezelo lweoyile lunqunyanyisiwe, kamsinya nje ukuba umphetho osezantsi webhanti yokukhupha ioyile ungene kumbhobho weoyile, indlela ephakathi kombhobho weoyile woxinzelelo oluphezulu. kwaye igumbi lokumpompa linqunyulwe. Xa i-valve yokuhanjiswa kweoyile ihleli ngokupheleleyo, yehla umgama h, ngoko ke umthamo wombhobho weoyile woxinzelelo oluphezulu uyanda, obangela ukuba uxinzelelo lweoyile lwehle ngokukhawuleza nge-1MPa ~ 2MPa, kwaye ioyile inqunyulwe ngokukhawuleza nangokulula, ukuthintela ukuguquguquka kwe-oyile kunye "nokuncipha kombhobho" ekubangeleni ukunyuka kweoli. "Kwaye uvelise i-oyile ethontsizayo emva kokutshiza. (3) Thintela amafutha ukuba angahambi ngasemva kwaye ugcine uxinzelelo oluthile olushiyekileyo kumbhobho weoli woxinzelelo oluphezulu.
