Iivalvu zebhabhathane zomoyaziyinxalenye ebalulekileyo kwiinkqubo zolawulo lolwelo lwemizi-mveliso zanamhlanje kwaye zezinye zezona zisombululo zisebenziseka lula nezingabizi kakhulu. Zisetyenziswa kumashishini aqala ekucutshungulweni kweekhemikhali ukuya kunyango lwamanzi kunye neoyile negesi. Eli nqaku lixoxa ngokweenkcukacha ngomgaqo wokusebenza, iingenelo eziphambili, iimpawu zobugcisa, kunye neemeko zokusetyenziswa kweevalvu zebhabhathane ezine-pneumatic.
1. Yintoni ivalvu yebhabhathane ephuma emoyeni?
Ivalvu yebhabhathane ephefumlayo yindibaniselwano yevalvu yebhabhathane kunye ne-actuator ye-pneumatic, esebenzisa umoya ocinezelweyo ukulawula ukusebenza kwevalvu. Umbindi wayo yidiski efana nediski ejikeleza ngaphakathi kombhobho ukulawula okanye ukwahlukanisa ukuhamba kolwelo okanye igesi. Uyilo lwayo olulula, ukusebenza ngokukhawuleza, kunye nokusebenza okungabizi kakhulu kwenza ukuba ibe yenye indlela ekhethwayo kunevalvu zebhola okanye iivalvu zesango, ingakumbi kwimibhobho emikhulu.
2. Umgaqo wokusebenza weValve yeButterfly yePneumatic
Iivalvu zebhabhathane ezisebenzisa umoya ocinezelweyo zisebenzisa umoya ocinezelweyo ukujikeleza isiqu sevalvu, esithi sona sijikeleze idiski ngama-90° ujikeleze i-axis yaso, ngaloo ndlela silawula ukuhamba kolwelo. Indawo yokuqala yevalvu (ivuliwe okanye ivaliwe) imiselwe ngokweemfuno zokwenyani. Nantsi indlela esebenza ngayo: Umoya ocinezelweyo ungena kwi-actuator ye-pneumatic, utyhala i-piston okanye i-diaphragm ukujikeleza isiqu sevalvu, esithi sona sijikeleze idiski.
2.1 Ukusebenza Komnye Xa Kuthelekiswa Nokusebenza Kabini:
- Ukusebenza Kanye: Umoya usetyenziselwa ukuvula okanye ukuvala ivalvu. Intwasahlobo eyakhelwe ngaphakathi ibuyisela ivalvu kwindawo yayo yokuqala (ngesiqhelo ivuleka okanye ivaliwe) xa uxinzelelo lomoya luphela. Olu phawu lokubuyela kwentwasahlobo luyivala okanye luyivule ngokuzenzekelayo ivalvu xa umoya okanye umbane ucimile, nto leyo eyenza ifaneleke kwiindawo ezinobungozi kwaye ibonelele ngokhuseleko oluphuculweyo.
- Ukusebenza kabini: Uxinzelelo lomoya luyimfuneko ukulawula ukuvulwa nokuvalwa kwevalvu, ukubonelela ngolawulo oluchanekileyo kodwa ngaphandle kophawu lokuseta kwakhona oluzenzekelayo.
2.2 Isantya kunye nokuthembeka:
Ii-actuator ze-pneumatic zibonelela ngamaxesha okuphendula ngokukhawuleza (ukuya kuthi ga kwimizuzwana eyi-0.05 ngomjikelo ngamnye), ziqinisekisa ukuvulwa nokuvalwa ngokukhawuleza kweevalvu zebhabhathane, zinciphisa ixesha lokungasebenzi kwaye zithintele ukuguguleka okubangelwa kukunamathela. Iivalvu zebhabhathane ze-pneumatic zibonelela ngesantya sokuvulwa nokuvalwa esikhawulezayo kuzo zonke ii-actuator ze-butterfly valve.
Le ndlela yokujikeleza ngekota, idibene nolawulo oluchanekileyo lwe-actuator, yenza iivalvu zebhabhathane ezisebenzisa umoya zilungele iinkqubo ezizenzekelayo ezifuna ukusebenza ngokukhawuleza nangokuthembekileyo.
3. Iingenelo eziphambili zeevalvu zebhabhathane ze-Pneumatic
3.1. Ulwakhiwo Olulula Noluncinci:
Xa kuthelekiswa neevalvu zebhola okanye zesango, iivalvu zebhabhathane zithatha indawo encinci kwaye azidingi nkxaso ingako yolwakhiwo, nto leyo eyenza zifaneleke kwiipayipi ezincinci, eziphakathi nezinkulu.
3.2. Ixabiso Eliphantsi:
Izinto ezimbalwa kunye nokusetyenziswa kwezinto eziphantsi kubangela ukuba ixabiso lokuqala libe liphantsi kakhulu kunezinye iintlobo zeevalvu ze-caliber efanayo.
3.3. Ukusebenza ngokukhawuleza:
Ii-actuators zomoya zivumela ukuvulwa nokuvalwa ngokukhawuleza, ziphucula ukusebenza kakuhle kwenkqubo kunye nokuphendula kwayo, ingakumbi kwiimeko zikaxakeka.
3.4. Ukugcinwa Okuphantsi:
Uyilo olulula kunye nezixhobo ezihlala ixesha elide kunciphisa iimfuno zokugcinwa, kunciphisa ixesha lokungasebenzi kunye neendleko zokusebenza.
3.5. Ukwehla koxinzelelo oluphantsi:
Xa ivalvu ivuliwe ngokupheleleyo, idiski ihambelana necala lokuhamba kwamanzi, inciphisa ukumelana, inciphisa ukulahleka koxinzelelo, kwaye iphucula ukusebenza kakuhle kwamandla.
4. Ukusetyenziswa kweeValvu zeButterfly zePneumatic
- Unyango lwamanzi kunye namanzi amdaka: Ukulawula ukuhamba kwamanzi kunye nenqanaba lolwelo yeyona ndlela ilula yokusebenzisa iivalvu zebhabhathane.
