Yintoni iValve yeButterfly
Ivalvu yebhabhathane ibhekisa kwivalvu enenxalenye yokuvala (idiski yevalvu okanye ipleyiti yebhabhathane) njengediski, ejikeleza i-axis yevalvu ukuze kuvuleke kwaye kuvalwe. Isetyenziselwa ikakhulu ukusika nokubhoboza umbhobho. Inxalenye yokuvula nokuvala ivalvu yebhabhathane yipleyiti yebhabhathane enemilo yediski ejikeleza i-axis yayo emzimbeni wevalvu ukuze kufezekiswe injongo yokuvula nokuvala okanye ukumisela.
1. Ulwakhiwo lwevalvu yebhabhathane
Ivalvu yebhabhathane yenziwe kakhulu ngumzimba wevalvu, ipleyiti yebhabhathane, isiqu sevalvu, iringi yokutywina kunye nesixhobo sokudlulisa. Umzimba wevalvu ungqukuva, unebhosi ye-cylindrical kwiindawo eziphezulu nezisezantsi zokufaka isiqu sevalvu. Ivalvu yebhabhathane iqhagamshelwe kakhulu kumbhobho ngeflange; ukuba uqhagamshelo lweclamp luyasetyenziswa, ubude bayo bolwakhiwo lolona luncinci. ?Isiqu sevalvu ngumshaft ojikelezayo wepleyiti yebhabhathane, kwaye isiphelo seshaft sisebenzisa isakhiwo sokutywina ibhokisi yokuzalisa ukuthintela ukuvuza kwesixhobo. Isiphelo esiphezulu sesiqu sevalvu siqhagamshelwe ngqo kwisixhobo sokudlulisa ukuhambisa i-torque. Ipleyiti yebhabhathane yinxalenye yokuvula nokuvala yevalvu yebhabhathane. Ngokwendlela yoqhagamshelo, inokwahlulwa ibe luqhagamshelo lweflange kunye noqhagamshelo lweclamp; ngokwendlela yokudlulisa, inokwahlulwa ibe yi-manual, gear transmission, pneumatic, hydraulic kunye ne-electric.
I-engile ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo kwevalvu yebhabhathane idla ngokuba ngaphantsi kwama-90°. Ivalvu yebhabhathane kunye nesiqu sebhabhathane ngokwazo azinawo amandla okuzitshixa. Ukuze kubekwe ipleyiti yebhabhathane, kufuneka kufakwe isixhobo sokunciphisa ii-worm gear kwisiqu sevalvu. Ukusetyenziswa kwesixhobo sokunciphisa ii-worm gear akunakwenza nje kuphela ipleyiti yebhabhathane ibe namandla okuzitshixa kwaye kumise ipleyiti yebhabhathane kuyo nayiphi na indawo, kodwa kukwaphucula nokusebenza kwevalvu.
2. Umgaqo wokusebenza wevalvu yebhabhathane
Idiski yevalvu yidiski. Ngokujikeleza kwesiqu sevalvu, idiski yevalvu ijikeleza i-90° ngaphakathi komgama wesihlalo sevalvu ukuze ivule kwaye ivale ivalvu. Idlala indima yokuvala kwipayipi. Ingalungisa nokuhamba kwamanzi. ??
Iingenelo zevalvu yebhabhathane: isakhiwo esilula, umthamo okhanyayo, ukusebenza lula, ukuvalwa kakuhle.
3. Ukwahlulwahlulwa kweevalvu zebhabhathane
Iivalvu zebhabhathane zinokwahlulwa zibe ziivalvu ezintathu zebhabhathane ezingaqhelekanga (Triple offset), iivalvu zebhabhathane ezisebenza kakuhle (ezikwabizwa ngokuba ziivalvu zebhabhathane ezi-double-eccentric), kunye neevalvu zebhabhathane eziphakathi (ezikwabizwa ngokuba ziivalvu zerabha zesihlalo sebhabhathane) ngokwemo yesakhiwo.
Ngokwendlela yokutywina, zinokwahlulwa zibe luhlobo lokutywina oluthambileyo nohlobo lokutywina oluqinileyo (iivalvu zebhabhathane ezitywina nzima zahlulwe zibe ziivalvu zebhabhathane ezitywina ngamaleya amaninzi kunye neevalvu zebhabhathane ezitywina ngentsimbi ecocekileyo). Uhlobo lokutywina oluthambileyo ludla ngokusebenzisa ukutywina kweringi yerabha, kwaye uhlobo lokutywina oluqinileyo ludla ngokusebenzisa ukutywina kweringi yesinyithi.
4. Imigaqo yokukhetha iivalvu zebhabhathane
-Ekubeni ukulahleka koxinzelelo lweevalvu zebhabhathane kukhulu xa kuthelekiswa neevalvu zesango kunye neevalvu zebhola, zifanelekile kwiinkqubo zemibhobho ezineemfuno zokulahlekelwa koxinzelelo ezingqongqo.
-Ekubeni iivalvu zebhabhathane zinokusetyenziselwa ukulawula ukuhamba kwamanzi, zifanelekile kwiipayipi ezifuna ukulawula ukuhamba kwamanzi.
-Ngenxa yokunqongophala kwesakhiwo sevalvu yebhabhathane kunye nezinto zokutywina, ayifanelekanga kwiinkqubo zemibhobho ezinobushushu obuphezulu kunye noxinzelelo oluphezulu. Ubushushu obuqhelekileyo bokusebenza bungaphantsi kwama-300°C kwaye uxinzelelo oluqhelekileyo lungaphantsi kwe-PN40.
-Ekubeni ivalvu yebhabhathane inobude obufutshane besakhiwo kwaye inokwenziwa ibe yidayamitha enkulu, kuyacetyiswa ukusebenzisa ivalvu yebhabhathane kwiimeko apho ubude besakhiwo bufuneka ukuba bube bufutshane okanye ivalvu enkulu (efana ne-DN1000 okanye ngaphezulu).
-Ekubeni ivalvu yebhabhathane inokuvulwa okanye ivalwe ngokujikeleza i-90° kuphela, kuyacetyiswa ukusebenzisa ivalvu yebhabhathane kwiimeko apho kufuneka ivuleke kwaye ivalwe ngokukhawuleza.
Isishwankathelo
Iimarike zeevalvu zeebhabhathane bezikhula ngokukhawuleza kwiminyaka yakutshanje, kwaye uluhlu lwababoneleli beevalvu zeebhabhathane luye lwatshintsha. Xa sikhethaumzi-mveliso wevalvu yebhabhathane, kufuneka sidibanise iimfuno zethu, ezinje ngomgangatho, ixabiso, inkonzo kunye nezinye izinto, ukuze sikhetheumenzi weevalvu zebhabhathaneehlangabezana neemfuno zakho.
