Iivalve yedadaUkutywina iringi ye-sfdn80Ngaba icandelo lokutywina liyilelwe ngokukodwa kubalawuli benqanaba le-flaat. Yinto ejikelezayo ejikelezayo, ihlala yenziwa ngezinto zerabha ezifana nerabha okanye iplasitiki, ukulungelelanisa ukuhamba kwepiston xa kutsalwa ityholo lokudada kunye nokuqinisekisa ukutywinwa okusebenzayo ukukhusela ukuvuza okusebenzayo.

Kwiivali ezidadayo,I-valve yedada yokutsala i-sfdn80isetyenziselwa ukumelana noxinzelelo lwamanzi ngelixa igcina intsebenzo yokutywina kwevali edibeneyo kunye nepiston okanye i-piston okanye i-piston okanye i-piston okanye i-piston okanye i-piston okanye i-piston okanye i-piston okanye i-float. Xa inqanaba lolwelo kwitanki yamafutha okanye esinye isikhongozelo siphuma, ukunyuka kwe-float kwaye ipiston ihamba ngokufanelekileyo. I-ring yokutywina kufuneka ichaphazele ngokwendlela yokuhamba kwepiston ukugcina i-valve ivaliwe kwaye ikhusele ulwelo olugqithisileyo ekungeneni kwisitya. Ngokuchasene noko, xa inqanaba le-wolting lihla, i-float kunye nokutsala i-ring kunye ne-piston ivule, ivumela ulwelo, uvumele iphinde iphinde iphinde ikhuphe kwisitya.

Uyilo lweivalve yedadaUkutsalela umnxebaSfdn80Kufuneka ube nakho ukugcina ubume babo kunye nokusebenza kwazo phantsi kwendlela yobushushu obahlukeneyo kunye neemeko zoxinzelelo, ngelixa ukwazi ukumelana nolwelo olunokubakho kulwelo. Ke ngoko, izinto ezikhethiweyo zihlala zinokuchasana kakuhle nemichiza kunye nokuxhathisa ubushushu obuthile.

Xa ugcina kwaye utshintshisela amakhonkco okutywina, kuyimfuneko ukuqinisekisa ukuba ubungakanani kunye ne-pile yokutywina ihlangabezana neemfuno zoyilo lwevalton ye-piston okanye ibhola yedabi. Nakuphi na ukufaka okungafanelekanga kunokukhokelela ekuvuzelweni okanye eminye imiba yokusebenza.

II-valve yedada yokutsala i-sfdn80I-valve yedada yenye yezinto eziphambili zokusebenza okuqhelekileyo kwevalve yokudada, kunye nokusebenza kwayo kuchaphazela ngqo ukuchaneka kolawulo kunye nokuzinza kwenkqubo ye-valve yeflethi. Ke ngoko, ukukhetha iringi efanelekileyo yokutywina kunye nokuqinisekisa ukufakelwa kwayo ngokuchanekileyo kubalulekile ekuqinisekiseni ukuthembeka kunye nokusebenza kakuhle kwale nkqubo iphela.
