Kukhona indawo yokuvalwa kwamasango amabili, imodi evame kakhulu yokuvalwa kwe-valve yesango ukuze kwakheke ama-wedge amabili, i-engeli ye-wedge iyahlukahluka nemingcele ye-valve, imvamisa engu-50, okuphakathi akulona izinga lokushisa eliphezulu ngu-2 ® 52*.I-valve yesango le-Wedge ingenziwa ibe yonke, ebizwa ngokuthi isango eliqinile;futhi kwenziwe ukuze kukhiqizwe deformation encane yesango, ukuze kuthuthukiswe inqubo yayo, ukwenza uphawu ukuphambuka ebusweni angle eziphakamayo ngesikhathi processing, leli sango libizwa ngokuthi isango nezimo.
Lolu chungechunge lwemikhiqizo lunezici ezilandelayo:
1.Umzimba we-valve wamukela umfuziselo wesakhiwo ofanele izidingo zenqubo ye-lining;Ingaphakathi le-valve yomzimba, ikhava yevalvu nesango, indawo engaphandle yesiqu se-valve nezinye izingxenye ezixhumene ngqo nendawo ephakathi, zonke zifakwe i-FEP(F46) noma i-PCTFE(F3) namanye amapulasitiki e-fluorine;
2. Ukumelana noketshezi oluncane, indawo evalekayo ngokuguguleka kwe-Chong ibhulashi eliphakathi nendawo nelincane
3.Vula futhi uvale umzamo owengeziwe.
4.Ukugeleza kwemidiya okungakhawulelwe, okungekona okonakalisayo akunciphisi ingcindezi.
I-5.Yakha isakhiwo esilula, ubude obufushane, inqubo yokukhiqiza enhle, esebenza ezinhlobonhlobo eziningi.
I-6.I-medium ingadlula i-valve yesango kunoma iyiphi indlela evela ezinhlangothini zombili, efanelekile idivayisi yokuvula nokuvala epayipini lapho isiqondiso esiphakathi singashintsha.
7.PFA/FEP ulayini, olunokuqina kwamakhemikhali aphezulu, lungasetshenziswa kunoma iyiphi enye imidiya egqwalayo eqinile ngaphandle kokuthi "insimbi encibilikisiwe ye-alkali ne-elementi ye-fluorine".
