Kukho umphezulu wokutywina wamasango amabini, eyona ndlela iqhelekileyo yevalve yesango yokutywina umphezulu ukwenza i-wedge emibini, i-angle ye-wedge iyahluka kunye neeparamitha zevalve, idla ngokuba yi-50, i-medium ayikho phezulu yi-2 ® 52*.Ivalve yesango leWedge inokwenziwa ngokupheleleyo, ebizwa ngokuba lisango eliqinileyo;kwakhona kwenziwe ukuvelisa deformation encinane yesango, ukuze kuphuculwe inkqubo yayo, ukwenza ukutenxa engile umphezulu wokutywina evela ngexesha processing, eli sango libizwa ngokuba isango bhetyebhetye.
Olu luhlu lweemveliso luneempawu ezilandelayo:
1.Umzimba wevalvu wamkela imodeli yesakhiwo esifanelekileyo kwiimfuno zenkqubo ye-lining;Umngxuma ongaphakathi womzimba wevalvu, isigqubuthelo sevalvu kunye nesango, umphezulu ongaphandle wesikhondo sevalvu kunye namanye amalungu adibane ngqo nophakathi, onke ane-FEP(F46) okanye iPCTFE(F3) kunye nezinye iiplastiki zefluorine;
2. Ukuxhathisa ulwelo oluncinci, indawo yokutywina ngokukhukuliseka kweChong ibrashi ephakathi kunye encinci
3.Vula kwaye uvale umzamo ongakumbi.
I-4.I-Media flow flowing, non spoiler musa ukunciphisa uxinzelelo.
5.Ifomu isakhiwo esilula, ubude obufutshane, inkqubo yokuvelisa kakuhle, esebenzayo kuluhlu olubanzi.
6.I-medium inokudlula kwi-valve yesango kuyo nayiphi na indlela ukusuka kumacala omabini, efanelekileyo kwisixhobo sokuvula kunye nokuvala kwipayipi apho ulwalathiso oluphakathi lunokutshintsha.
I-7.PFA/FEP lining, enozinzo oluphezulu lweekhemikhali, inokufakwa kuyo nayiphi na enye imidiya eyomeleleyo eyonakalisayo ngaphandle kwe "alkali metal metal and element fluorine".
