Yintoni iValve yeButterfly: Imiyalelo eneenkcukacha ezisebenzayo

Yintoni iValve yeButterfly

A ivalvu yebhabhathaneyivalvu ejika ikota enediski ejikelezayo (ipleyiti yebhabhathane) eqhotyoshelwe kwisiqu esiphakathi. Olu yilo luncinci lwenza ukuba kulawulwe ukuhamba kwamanzi ngokukhawuleza okanye kuhlukaniswe kwimibhobho. Zisetyenziswa kakhulu kumashishini onke, iivalvu zebhabhathane ziyagqwesa kwizicelo ezifuna izisombululo ezingabizi kakhulu nezikhaphukhaphu ezinoxinzelelo oluphantsi.

Ulwakhiwo lweValve yeButterfly: Izinto ezi-4 ezibalulekileyo

1. Umzimba weValve: Indlu yesangqa (intsimbi ephosiweyo, intsimbi engatyiwayo, okanye intsimbi ethambileyo) eneziphelo ezijijekileyo/ezilukiweyo/eziweldayo.

2. Idiski yeValve: Ukuhamba kokulawula iipleyiti ezijikelezayo – kufumaneka kwiindlela ezijikelezayo, eziphindwe kabini/kathathu.

3. Isiqu: Iqhagamshela i-actuator kwidiski ukuze idlulisele i-torque.

4. Isihlalo: Umphezulu wokutywina (irabha ethambileyo, i-PTFE, okanye isinyithi) oqinisekisa ukuvalwa okuqinileyo nokuvuza.

Zisebenza njani iiValve zeButterfly

Iivalvu zebhabhathane zizinto ezibalulekileyo kwiinkqubo zanamhlanje zokulawula ulwelo, ezixatyiswa ngokulula kwazo, uyilo oluncinci, kunye nokusebenza ngokukhawuleza. Kodwa isebenza njani kanye kanye le valve iguquguqukayo?

Umgaqo-siseko oSebenzayo: Idiski ejikelezayo

Intliziyo yevalvu yebhabhathane yidiski ejikelezayo (okanye ivane) efakwe kwisiqu esijikelezayo ngaphakathi kwebhore yombhobho. Ulawulo lolwelo lufezekiswa ngokupheleleyo ngentshukumo ephambili yediski:

Idiski ijikeleza i-90° phakathi:

-Ivuliwe Ngokupheleleyo: Idiski ihambelana ngokuhambelana nokuhamba (ukulahlekelwa koxinzelelo oluncinci)

-Ivaliwe ngokupheleleyo: Iibhloko zediski zihamba ngokuthe nkqo kumbhobho

Ukuqaliswa Kokuvula Nokuhamba Komoya: Ukujikeleza ukuya kwimvume yokuhamba komoya

• Xa isebenza (ngesandla ngevili lesandla, okanye ngokuzenzekelayo ngezixhobo zombane/zomoya), isiqu sijikeleza idiski ukusuka kwindawo yayo evaliweyo (ethe nkqo ukuya kwindawo ejikelezayo) ukuya kwindawo evulekileyo.

• Njengoko idiski ijikeleza (ngesiqhelo ukusuka kwi-0° ukuya kwi-90°), isuka kwisitulo sevalvu, idala indlela yokuba ulwelo luhambe ngayo emacaleni ayo kunye/okanye ngomngxuma ophakathi ukuba ukhona.

• I-engile yokuvula ihambelana ngokuthe ngqo nomthamo wokuhamba kwamanzi, nto leyo evumela uhlengahlengiso oluchanekileyo olusekelwe kwimfuno yenkqubo.

Ulawulo Lokuhamba Okuchanekileyo: I-Angle Ilawula Isantya

• Amandla aphambili eevalvu zebhabhathane kukukwazi kwazo ukugoba kakuhle. Ngokulawula i-engile yokujikeleza kwediski, abaqhubi bafumana ulawulo lokuhamba komgca.

• Xa ijikeleza malunga ne-90° (idiski ihambelana nokuhamba), idiski inika ukuxinana okuncinci, inika ukuhamba okuphantse kuzaliseke kwindawo yombhobho kunye nesantya esiphezulu sokuhamba.

• Kwii-engile eziphakathi (umz., 30°, 45°, 60°), idiski iyayithintela kancinci indlela yokuhamba kwamanzi, inciphisa ngokufanelekileyo indawo yokuhamba kwamanzi kwaye ivumela ukulawulwa kokuhamba kwamanzi okulungisiweyo.

Ukuvalwa Okuhle: Ukutywina Ukuchasana Nokuhamba

Ukuze kumiswe ukuhamba ngokupheleleyo, i-actuator ijikelezisa idiski ibuyele kwindawo ye-0° (ithe nkqo ukuya ekuhambeni).

Kule ndawo, umngcelele wediski ucinezela ngokuqinileyo kwisihlalo esiqinileyo se-elastomeric (umz., i-EPDM, i-Nitrile, i-PTFE) esibotshelelwe okanye esigcinwe emzimbeni wevalvu, okwenza isitywina esiqinileyo se-bubble sokwahlulwa kokuhamba kwamanzi ngokupheleleyo.

Umsebenzi owongezelelweyo: Usetyenziso loLawulo lweNqanaba

Ngaphandle kokuvula/ukuvala nokuqhobosha okulula, iivalvu zebhabhathane ngamanye amaxesha zinokusetyenziselwa ukulawula inqanaba (intloko) kwiitanki okanye kwiindawo zokugcina amanzi. Ngokuguqula i-engile yediski, izinga lokuphuma kwamanzi liyalungiswa, nto leyo echaphazela ngokungathanga ngqo inqanaba lolwelo oluphezulu.

Iimpawu eziphambili zokusebenza kunye nezinto zokukhetha:

Ukuqonda le migaqo yokusebenza kugxininisa iinkalo ezibalulekileyo zokusebenza ezibalulekileyo ekukhetheni nasekusebenziseni iivalvu ngokufanelekileyo:

√Ukuhla koxinzelelo (Ukulahleka):Iivalvu zebhabhathane zibonisa ukwehla koxinzelelo oluphantsi kakhulu xa zivuliwe ngokupheleleyo (ngenxa yokuxinana okuncinci) kwaye ngokuqinisekileyo aziwi xa zivaliwe (ukuvalwa okugcweleyo). Nangona kunjalo, kwiindawo ezivulekileyo kancinci (ukugoba), idiski idala ukuphazamiseka okukhulu kunye nokuphazamiseka kokuhamba kwamanzi, okukhokelela ekulahlekelweni koxinzelelo okuphezulu xa kuthelekiswa neevalvu ezigcweleyo ezifana neevalvu zesango. Le yinto ebalulekileyo ekusebenzeni kakuhle kwamandla kwinkonzo yokugoba.

√Imidiya Efanelekileyo:Iivalvu zebhabhathane zibalasele ngolwelo olucocekileyo, iigesi, kunye nomphunga - izinto ezisetyenziswa lula "ukunqunyulwa" yidiski.

√Ama-slurries okanye i-media enomxholo ophezulu wezinto eziqinileyo:Amasuntswana arhabaxa anokonakalisa umphetho wediski aze onakalise isihlalo esithambileyo, nto leyo enokubeka emngciphekweni ukutywinwa. Sicebisa ukuba usebenziseIivalvu zeButterfly zeSihlalo seMetalokanye iValve yeSango leSlurry

Ngokuqhelekileyo AZICETYISWA xa:

χUlwelo oluxineneyo kakhulu okanye imidiya etyekele ekukhanyeni: Ezi zinokubangela ukunamathela, ukuthintela ukuvalwa ngokupheleleyo, okanye zonakalise isihlalo. Sicebisa ukuba kusetyenziswe iiValve zeBhola eziSegment.
