Ukukhangela ukuba undoqo wevalve yevili uyavuza
Ukukhangela ukuba iivalve yetayaraukuvuza okungundoqo, unokufaka isepha kumbindi wevalve ukujonga, ukuba ukuvuza kuya kuva isandi esithi "Sizzling", okanye ubone iqamza elincinci eliqhubekayo. Qwalasela isivalo sevalvu phambi kokwenyuka. Ukuba ivalve ivelufa kunye core ivelufa ngembi, engalinganiyo, akukho lula ukufutha. Ukuba umbhobho wevalve kunye nombindi wevalve zilingana kakuhle, ivalve kufuneka icocwe, ngelixa ivalve kunye nombindi wevalve zilungisiwe, musa ukukhululeka. Ukuya kumlinganiselo ochanekileyo wokunyuka kwamaxabiso, uxinzelelo lwetayara alukwazi ukuphakama kakhulu, uxinzelelo oluphezulu lwetayara luya kwenza ukuba intambo yesondo ibe yolule kakhulu, okukhokelela ekunciphiseni amandla, kuchaphazela ubomi betayara. Umoya ogcweleyo awufanele ube nomswakama okanye ezinye izinto ezingcolileyo zokuthintela ukuwohloka okanye umonakalo kwirubha yesondo. Xa imoto isanda kumisa, musa ukuvuthela, kuba ngeli xesha ubushushu begesi kwivili buphezulu, uxinzelelo lwetayara, ukulinda ukuba ivili liphole ngaphambi kokunyuka.
ivalufa yetayara kunye nesiseko sevalve
Ukuba i-valve core isetyenziswe ixesha elide kakhulu, iya kuba mdala kwaye ibambelele kudonga lwangaphakathi lombhobho wevalve, okukhokelela ekwahlukaneni kwesihlalo sevalve kunye nomzimba ongundoqo, kwaye kunzima ukususa indawo eshiyekileyo yombhobho wevalve. Ukuba umlomo wevalve kancinane deformation okanye umonakalo wangaphakathi umsonto, undoqo ivelufa screwed kumlomo ivelufa ayikwazi ukususwa, kweli nqanaba undoqo wevalve ujijelwe ukuya ekupheleni, kwaye ke isikrufu core ivelufa ngempompo kumsonto wangaphakathi unokususwa; Ukuba ayichithwanga, iya kukwazi ukucoca indawo yokucoca, kwaye ngokuhlaselwa kwesilika kumazinyo angama-5 -6, ivalve engundoqo yevalve ngaphandle, kwaye ke ufake i-core valve entsha. Ukuba i-valve core thread inomhlwa ifile, inokuwisa amathontsi ambalwa epetroli kumngxunya wevalve okanye intywiliselwe kwipetroli, emva komzuzwana ize iwise amathontsi ambalwa e-oyile inokususwa. Ukuba i-screw yevalve yangaphakathi i-screw, i-screw phantsi kwe-nut yoxinzelelo yonakalisiwe, isihlalo sigobile, okanye ityhubhu yevalve yevalve yonakalisiwe kwaye ayivalwanga, kufuneka itshintshwe.
Lungisa ivalve yamatayara
Ivalve yetyhubhu yangaphakathi eyonakeleyo, enje ngentambo yokuqhoboshela, inokulungiswa yiTephu kwaye ufe. Umlomo wevalve yokutshintsha kufuneka uthathwe kwityhubhu yangaphakathi ngesithuba, ukuba akukho sikhewu jikisa udonga lwangaphakathi lombhobho, unokusika i-7-8 mm yokuphuma; Faka iphedi yebhulorho kwaye uqinise i-nut yentloko yevalve ngesitshixo. Intloko yebhulorho yombhobho wevalvu iya kufakwa kunye ne-axis yayo engqukuva ende elungelelaniswe kwisangqa setyhubhu yangaphakathi kunokuba ithe tye, kwaye intloko yebhulorho ayisayi kugotywa, kwaye isiphelo sayo siya kusekwa kwi-30 ° . I-bridgehead kufuneka ifakwe ijonge ngaphandle, kunye nesiphelo esigobileyo sevalve sijongene ngaphaya kombhobho ukuzalisa isilonda; umngxuma osikiweyo ukususa okanye ukufaka isiphelo sevalve kufuneka sifakwe kakuhle. Xa utshintshela umbhobho werabha kumbhobho wangaphakathi wesithuthi esiphathwayo, umlomo wevalve endala unokusikwa ngemela kwaye inxalenye eseleyo yomlomo wevalvu inokukhuhlwa kumbhobho wangaphakathi ngevili lokusila lesilicon carbide, emva koko ugalele iglu kwindawo egruzukileyo kunye nesitulo esitsha sevalve yerabha (i-flange) kwaye yome. Beka isihlalo sevalve esitsha endaweni ukuze isitulo sevalve singqinelane ncakasana nesitulo setyhubhu kwaye umphetho werubha wesihlalo sevalve ufakwe kwisitulo setyhubhu; qengqeleka isitulo sevalve, kwaye uvulcaza lwenziwa kwipleyiti ecaba esetyenziselwa ivalve ekhethekileyo yokuvuthuza.
