IVALAVA YENTLALO

Iivalvu zenalitiingasetyenziswa ngesandla okanye ngokuzenzekelayo. Iivalvu zeenaliti ezisetyenziswa ngesandla zisebenzisa ivili lesandla ukulawula umgama phakathi kwe-plunger kunye nesihlalo sevalvu. Xa ivili lesandla lijikeleziswa kwicala elinye, i-plunger iyaphakanyiswa ukuvula ivalvu kwaye ivumele ulwelo ukuba ludlule. Xa ivili lesandla lijikeleziswa kwelinye icala, i-plunger isondela kwisihlalo ukuze yehlise isantya sokuhamba okanye ivale ivalvu.

Iivalvu zeenaliti ezizenzekelayo ziqhagamshelwe kwi-hydraulic motor okanye kwi-air actuator evula kwaye ivale i-valve ngokuzenzekelayo. I-motor okanye i-actuator iya kulungisa indawo ye-plunger ngokwee-timers okanye idatha yokusebenza yangaphandle eqokelelwe xa kubekwa esweni oomatshini.

Zombini iivalvu zenaliti ezisebenza ngesandla nezizenzekelayo zibonelela ngolawulo oluchanekileyo lwesantya sokuhamba kwamanzi. Ivili lesandla lifakwe imisonto emincinci, oko kuthetha ukuba kuthatha ukujika okuphindaphindiweyo ukulungisa indawo ye-plunger. Ngenxa yoko, ivalvu yenaliti inokukunceda ulawule ngcono isantya sokuhamba kolwelo kwinkqubo.

Iivalvu zeenaliti zihlala zisetyenziselwa ukulawula ukuhamba kwamanzi nokukhusela iigeyiji ezibuthathaka kumonakalo obangelwa kukunyuka koxinzelelo olukhawulezileyo kolwelo kunye neegesi. Zilungele iinkqubo ezisebenzisa izinto ezikhaphukhaphu nezingenabugocigoci ezinezinga lokuhamba kwamanzi eliphantsi. Iivalvu zeenaliti zihlala zisetyenziswa kwiinkqubo ze-hydraulic ezinoxinzelelo oluphantsi, ekucutshungulweni kweekhemikhali, nakwezinye iinkonzo zegesi kunye nolwelo.

Ezi valve zingasetyenziswa nakwinkonzo yobushushu obuphezulu kunye neoksijini ngokusekelwe kwizinto ezisetyenziswayo. Iivalvu zeenaliti zihlala zenziwe ngentsimbi engagqwaliyo, ibronzi, ibronzi, okanye i-alloys zesinyithi. Kubalulekile ukukhetha ivalvu yeenaliti eyenziwe ngezinto ezifanelekileyo kakhulu kwinkonzo oyifunayo. Oku kuya kunceda ukugcina ubomi benkonzo yevalvu kwaye kugcine iinkqubo zakho zisebenza kakuhle nangokukhuselekileyo.

Ngoku ekubeni ufunde iziseko zombuzo oqhelekileyo; ivalvu yenaliti isebenza njani? Funda ngakumbi malunga nomsebenzi weevalvu zenaliti kunye nendlela yokukhetha ivalvu yenaliti efanelekileyo yokusetyenziswa okuthile, ngokui-CZIT efumana isivumelwano.
