Ngophuhliso oluqhubekayo loqoqosho lwentlalo, iimfuno zezixhobo zoshishino ezivela kuzo zonke iinkalo zobomi nazo ziphezulu kwaye ziphezulu.Ivalve yebhabhathane yerabha enerabha yivalve esetyenziswa kakhulu kushishino.Eli nqaku liza kwazisa ukusetyenziswa kwevalve yebhabhathane yerabha efakwe emoyeni kwishishini ngokweenkcukacha.
1. Umgaqo osisiseko wevalve yebhabhathane yerabha ene-pneumatic
Ivalve yebhabhathane yerubha ene-pneumatic yenziwe nge-actuator yomoya, ipleyiti yebhabhathane, isitulo sevalvu, intonga yevalvu, i-valve rod gasket, ipleyiti yoxinzelelo lwasentwasahlobo, i-lining, njl. kwaye yenza ipleyiti yebhabhathane ijikeleze, ngaloo ndlela ifezekise injongo yokuvula nokuvala umbhobho.Ngexesha elifanayo, i-rubber ye-lining material inokutywina imidiya eyahlukeneyo kwaye inoluhlu olubanzi lwezicelo.
2. Intsimi yesicelo se-pneumaticIvalve yebhabhathane enerabha
Iivalvu zebhabhathane zerubha ezinomoya zisetyenziswa kakhulu kwiikhemikhali, kumayeza, kumandla ombane, kwipetroleum, kwisinyithi, kushishino olukhanyayo, ukutya kunye namanye amashishini.Phakathi kwabo, imboni yeekhemikhali yenye yeenkalo zayo eziphambili zesicelo.Ngenxa yokuba imboni yeekhemikhali ineentlobo ezininzi zeendaba kunye neendawo zokusebenza ezimbi, i-valve ye-butterfly ene-rubber ene-pneumatic ineempawu zokumelana nokugqwala, ukuxhathisa ukugqoka kunye nokutywinwa okulungileyo, okunokuhlangabezana neemfuno zeshishini lemichiza.
3. Izinto eziluncedo zerubha ye-pneumatic lined butterfly valve
① Ukumelana nomhlwa okulungileyo
Umgca wevalve yebhabhathane yerabha eyenziwe ngerubha, enokumelana kakuhle nokhukuliseko lwemithombo yeendaba eyingozi efana neasidi, ialkali kunye netyuwa.
② Ukuxhathisa okuqinileyo
Ivalve yebhabhathane yerabha ene-pneumatic ithanda ukunxitywa ngenxa yokukhuhlana kwelayini ngexesha lokusetyenziswa.Nangona kunjalo, ubunzima bezinto ze-rubber ze-rubber ziphantsi kunezo zentsimbi, ngoko ke ukuxhatshazwa kwe-abrasion kunamandla.
③ Ukutywinwa kakuhle
Isixhobo somgca wevalve yebhabhathane enerabha enerabha inomsebenzi omhle wokutywina kumajelo osasazo ahlukeneyo, anokuqinisekisa ukuba umbhobho awuvuzi.
④ Ulondolozo olufanelekileyo
Ivalve yebhabhathane enerabha enerabha inesakhiwo esilula, kulula ukuyilungisa nokutshintsha, kwaye igcina iindleko zokugcinwa kunye nexesha.
4. Imigqaliselo yokukhethwa kwevalve yebhabhathane yerabha ene-pneumatic
① Uluhlu lobushushu
Ukukhethwa kwe-valve ye-butterfly ene-rubber ye-pneumatic kufuneka kuthathelwe ingqalelo uluhlu lweqondo lokushisa eliphakathi, kwaye ukhethe i-lining, intonga ye-valve kunye nezinye iinqununu zezinto ezahlukeneyo.
② Ukukala koxinzelelo
Ukukhethwa kwevalve yebhabhathane enerabha enerabha yomoya kufuneka kuthathelwe ingqalelo inqanaba loxinzelelo lombhobho kwaye ukhethe umzimba wevalvu efanelekileyo, ipleyiti yoxinzelelo lwasentwasahlobo kunye namanye amalungu.
③ Uhlobo lwemidiya
Ukukhethwa kwe-valve ye-butterfly ene-rubber ene-pneumatic kufuneka kuthathelwe ingqalelo iipropati ze-medium, ezifana ne-corrosivity, i-viscosity, i-flow rate, i-particle content, njl.
Ukushwankathela, ivalve yebhabhathane yerabha ene-pneumatic ineengenelo zokungagugi, ukumelana nokubola kunye nokutywinwa kakuhle, kwaye isetyenziswe ngokubanzi kwimichiza, amayeza, amandla ombane, i-petroleum nakwamanye amashishini.Nangona kunjalo, uluhlu lweqondo lokushisa, ibakala loxinzelelo kunye nohlobo oluphakathi kufuneka lunikwe ingqwalasela ngexesha lokukhetha ukuqinisekisa ukusebenza kwayo okuqhelekileyo kunye nokwandisa ubomi benkonzo.
