Ingxenye yokuvula neyokuvala ye-i-valve yesango lomliloyinqama, futhi isiqondiso sokunyakaza kwenqama sibhekene nesiqondiso soketshezi.I-valve yesango ingavulwa ngokugcwele futhi ivalwe ngokugcwele, futhi ayikwazi ukulungiswa nokuphonswa.Inqama inezindawo ezimbili zokuvala.Imodi esetshenziswa kakhulu ukuthi izindawo ezimbili zokuvala ze-valve yenqama zakha umcengezi.I-engeli ye-wedge iyahlukahluka nemingcele ye-valve, ngokuvamile engu-50. Uma izinga lokushisa eliphakathi lingekho phezulu, liyi-2 ° 52 '.Isango le-valve yesango le-wedge lingenziwa libe liphelele, elibizwa ngokuthi isango eliqinile;Ingenziwa futhi inqama engakhiqiza ukuwohloka okuncane ukuze kuthuthukiswe ukucutshungulwa kwayo futhi yenze ukuchezuka kwe-engeli yokuvala uphawu ngesikhathi sokucubungula.Le nqama ibizwa nge-elastic ram.
Izinhlobo zama-valve esango lomlilo zingahlukaniswa zibe ama-valve esango le-wedge kanye nama-valve esango ahambisanayo ngokuvumelana nokucushwa kwendawo yokubeka uphawu.Ama-valve wesango le-Wedge angabuye ahlukaniswe abe uhlobo lwesango elilodwa, uhlobo lwepuleti lesango eliphindwe kabili kanye nohlobo lwesango lokunwebeka;I-valve yesango elihambisanayo ingahlukaniswa ngepuleti lesango elilodwa kanye nepuleti lesango eliphindwe kabili.Ngokusho kokuma kwentambo ye-valve stem, ingahlukaniswa ngezinhlobo ezimbili:i-valve yesango ye-stem ekhuphukayofuthiI-valve yesango ye-stem engavuki.
Izici ze-valve yesango lomlilo:
1. Isisindo esilula: umzimba wenziwe nge-high-grade nodular black cast iron, futhi isisindo singaphansi kuka-20% ~ 30% ngaphansi kwe-valve yesango lendabuko, elilungele ukufakwa nokugcinwa.
Isihlalo sesango esiphansi esiphansi: ngemva kokuba i-valve yesango yendabuko igezwe ngamanzi, izinto zangaphandle njengamatshe, izigxobo zezinkuni, usimende, ama-iron chips kanye nama-sundries afakwa emgodini ongezansi kwe-valve, okulula ukubangela ukuvuza kwamanzi ngenxa ukungakwazi ukuvala ngokuqinile.Iphansi le-elastic seat seal valve lithatha idizayini efanayo ephansi eyisicaba njengaleyo yomshini wamapayipi amanzi, okungelula ukubangela ukuthi ama-sundries afake futhi enze ukugeleza koketshezi kungavinjwa.
2. I-Integral rubber coating: inqama ithatha irabha yekhwalithi ephezulu yokugqoka irabha yangaphakathi nangaphandle.Ubuchwepheshe be-European class vulcanization vulcanization buvumela inqama ethintekile ukuthi iqinisekise ubukhulu obunembile bejiyomethri, futhi i-RAM yerabha ne-ductile iron casting ixhumeke ngokuqinile, akulula ukuwa futhi ibe nenkumbulo enhle enwebekayo.
3. Umzimba we-valve yokuphonsa ngokunemba: umzimba we-valve wenziwe ngokunemba kokuphonswa, futhi ubukhulu bejiyomethri obunembile benza kube nokwenzeka ukuqinisekisa ukuvaleka kwesivalo ngaphandle kokuqedwa ngaphakathi komzimba wevalvu.
