Iivalve zebhabhathane zepneumaticziyinxalenye eyimfuneko kwiinkqubo zale mihla zolawulo lwamanzi kwimizi-mveliso kwaye sesinye sezisombululo ezinoguquguquko nezingabizi kakhulu. Zisetyenziswa kumashishini asusela ekusetyenzweni kweekhemikhali ukuya kunyango lwamanzi kunye neoyile negesi. Eli nqaku lixubusha ngokweenkcukacha umgaqo wokusebenza, iingenelo eziphambili, iimpawu zobugcisa, kunye neemeko zesicelo se-pneumatic butterfly valves.
1. Yintoni ivalve yebhabhathane yepneumatic?
Ivalve yebhabhathane yepneumatic yindibaniselwano yevalve yebhabhathane kunye ne-actuator yomoya, esebenzisa umoya ocinezelweyo ukulawula ukusebenza kwevalvu. Ingundoqo yayo i-disc-shaped disc ejikelezayo ngaphakathi kombhobho ukulawula okanye ukwahlula ukuhamba kwamanzi okanye igesi. Uyilo lwayo olulula, ukusebenza ngokukhawuleza, kunye nokusebenza kwezoqoqosho kwenza kube yinto ekhethwayo kwiivalve zebhola okanye iivalve zesango, ngakumbi kwimibhobho yobubanzi obukhulu.
2. UMmiselo wokuSebenza weValve yeButterfly yomoya
Iivalvu zebhabhathane zepneumatic zisebenzisa umoya ocinezelekileyo ukujikelezisa isiqu sevalve, ethi yona ijikelezise idiskhi engama-90 ° ijikeleze i-axis yayo, ngaloo ndlela ilawula ukuhamba kolwelo. Indawo yokuqala yevalve (evulekileyo okanye evaliweyo) imiselwe ngokweemfuno zokwenyani. Nantsi indlela esebenza ngayo: Umoya ocinezelweyo ungena kwi-actuator yomoya, utyhala ipiston okanye idiaphragm ukuze ujikelezise isikhondo sevalvu, ethi yona ijikelezise idiski.
2.1 Ukwenza umntu omnye vs. UkuSebenza kabini:
- Ukwenza into enye: Umoya usetyenziselwa ukuvula okanye ukuvala ivalve. Intwasahlobo eyakhelwe-ngaphakathi ibuyisela ivalve kwindawo yayo yokuqala (ngokuqhelekileyo ivulekile okanye ivaliwe) xa ilahleko yoxinzelelo lomoya. Olu phawu lokubuyisela entwasahlobo luvala ngokuzenzekelayo okanye luvula ivalve xa kukho umoya okanye umbane ophumayo, okwenza ukuba ifaneleke kwiindawo ezinobungozi kunye nokubonelela ngokhuseleko olongezelelweyo.
- UkuSebenza kabini: Uxinzelelo lomoya luyafuneka ukulawula kokubili ukuvulwa kunye nokuvalwa kwevalve, ukubonelela ngolawulo oluchanekileyo kodwa ngaphandle kwesici sokusetha ngokuzenzekelayo.
2.2 Isantya kunye nokuthembeka:
I-actuator ye-pneumatic inika amaxesha okuphendula ngokukhawuleza (ukuya kwi-0.05 imizuzwana ngomjikelo ngamnye), ukuqinisekisa ukuvulwa ngokukhawuleza kunye nokuvalwa kwee-valve ze-butterfly, ukunciphisa ixesha lokuphumla kunye nokuthintela ukuguga okubangelwa ukunamathela. Iivalvu zebhabhathane zepneumatic zibonelela ngesantya esikhawulezayo sokuvula kunye nokuvala kuzo zonke iivalvu zebhabhathane.
Le ndlela yokujikeleza ikota, idityaniswe nolawulo oluchanekileyo lwe-actuator, yenza iivalvu zebhabhathane zepneumatic zilungele iinkqubo ezizisebenzelayo ezifuna ukusebenza ngokukhawuleza nangokuthembekileyo.
3. Izinto eziluncedo eziPhambili zePneumatic Butterfly Valves
3.1. Ulwakhiwo olulula kunye noluQhelekileyo:
Xa kuthelekiswa neevalvu zebhola okanye zesango, iivalve zebhabhathane zithatha indawo encinci kwaye zifuna inkxaso encinci yesakhiwo, zizenze zilungele imibhobho emincinci, ephakathi, kunye nobubanzi obukhulu.
3.2. Isebenza kakuhle emalini:
Amalungu ambalwa kunye nokusetyenziswa kwemathiriyeli okusezantsi kubangela ixabiso lokuqala elisezantsi kakhulu kunezinye iindidi zeevalvu zohlobo olufanayo.
3.3. Ukusebenza ngokukhawuleza:
I-actuator ye-pneumatic ivumela ukuvula nokuvala ngokukhawuleza, ukuphucula ukusebenza kakuhle kwenkqubo kunye nokuphendula, ngokukodwa kwiimeko eziphuthumayo.
3.4. Ulungiso oluphantsi:
Uyilo olulula kunye nezinto ezihlala zihlala zinciphisa iimfuno zokugcina, ukunciphisa ixesha lokuphumla kunye neendleko zokusebenza.
3.5. Ukwehla koxinzelelo oluphantsi:
Xa i-valve ivulekile ngokupheleleyo, i-disc ihambelana nolwalathiso lokuhamba, ukunciphisa ukuchasana, ukunciphisa ukulahlekelwa kwengcinezelo, kunye nokuphucula ukusebenza kakuhle kwamandla.
4. Ukusetyenziswa kweeValuvu zeButterfly zomoya
- Ukucocwa kwamanzi kunye namanzi amdaka: Ukulawula ukuhamba kwamanzi kunye nenqanaba lolwelo yeyona nto isisiseko sokusetyenziswa kweevalve zebhabhathane.
- Ishishini lemichiza: Isetyenziselwa ukulawula ulwelo oludlekayo, oluxhotyiswe nge-PTFE okanye izinto zentsimbi engenakutyiwa ukwenzela ukonyuka kokuqina. - I-Oli neGesi: Iivalvu zebhabhathane ze-Eccentric pneumatic zifanelekile kuxinzelelo oluphezulu, imibhobho yamanzi yobushushu obuphezulu.
