Isebenza kanjani i-Flanged Gate Control Valve?

Buka Isithombe Esikhulu
Ama-valve ezimboni eza ngemiklamo ehlukene kanye nezindlela zokusebenza.Eminye ingeyokuhlukaniswa kuphela kuyilapho ezinye zisebenza kahle ekunyakazeni kuphela.

Ohlelweni lwamapayipi, kukhona ama-valve asetshenziselwa ukulawula ingcindezi, izinga lokugeleza nokunye okuthandwayo.Ama-valve anjalo okulawula asetshenziselwa ukuqapha nokulawula okuguquguqukayo kokugeleza ukuze lokhu okulandelayo kunamathele eduze ngangokunokwenzeka ekucacisweni okufunayo.Kodwa-ke, i-valve yokulawula ingenye ethathwa kakhulu njengama-valve epayipini njengoba le valve inemininingwane abanye onjiniyela abayithola inzima kakhulu.

Kunezinhlobo eziningi zamavalvu okulawula.Enye yazo yi-valve yokulawula isango eline-flanged.Lesi sihloko sidingida ukuthi i-valve yokulawula isango ene-flanged isebenza kanjani, ukusetshenziswa kwayo nokunye okuthandwayo.

Iyini i-Control Valve?

Ngencazelo, i-valve yokulawula yinoma iyiphi i-valve engakwazi ukulawula ukuhamba kwemidiya, izilinganiso zayo zokucindezela maqondana nedivayisi yokulawula yangaphandle.Ngokuvamile, ama-valve okulawula ahlotshaniswa nokulawulwa kokugeleza kwemidiya kodwa lezi zingashintsha nezinye izinto eziguquguqukayo zesistimu.

I-valve yokulawula ibhekwa njengengxenye ebaluleke kakhulu ye-loop yokulawula.Izinguquko ezenziwe i-valve yokulawula zithinta ngokuqondile inqubo ye-valve enjalo exhunywe kuyo.

Amavalvu ezimboni amaningana asebenza njengamavalvu okulawula njengoba kubonakala kuthebula elingezansi.Ama-valve ovemvane nawembulunga angasetshenziselwa ukuphonseka.Nakuba ama-valve ebhola nama-plug valve enekhono lokudonsa, lezi ngokuvamile azifanelekeli isevisi enjalo ngenxa yokwakheka kwalezi zinhlobo zama-valve ezimbili.Bathambekele ekulimaleni kokungqubuzana.

Ama-valve okulawula ahlanganisa izigaba ezahlukene ezivamile.Ingaba nokunyakaza komugqa okufana nokwembulunga, ukuncinza kanye namavalvu e-diaphragm.Ingase futhi ibe nokunyakaza okujikelezayo njengalokho kwebhola, uvemvane nama-valve epulaki.

Ngakolunye uhlangothi, ama-valve okuphepha anamandla okudambisa ingcindezi.Futhi, i-valve yeglobu, i-valve yebhola, kanye ne-valve yepulaki inamandla okushintsha isiqondiso sokugeleza kwemidiya.Nokho, kukhona okuhlukile.Ama-engeli eglobhu ama-engeli kuphela, ibhola le-multiport nama-plug valve angashintsha indlela yemidiya.

Control Valve Izici

Amavalvu okulawula angawomndeni onyakazayo olayini angakwazi ukucindezela amazinga okugeleza amancane.Ngokufanele izicelo zomfutho ophezulu, indlela yokugeleza yalolu hlobo lwevalvu iyahlanganiswa.Ukuhlinzeka ngokuvala okungcono, ibhonethi ihlukene.Izixhumi zivame ukuvuleka noma zifakwe imicu.

Control Valve Izici

Ama-valve eglobhu anezihlalo ezizodwa adinga amandla amakhulu ukuze anyakaze isiqu kodwa ahlinzeka ngokuvala okuqinile.Ngokuphambene, amavalvu embulunga anezihlalo ezimbili adinga amandla amancane ukuze ahambise isiqu kodwa awakwazi ukufeza ikhono lokuvala eliqinile levalvu yeglobhu ehlezi eyodwa.Ukwengeza, izingxenye zayo ziguga kalula.

Amavalvu e-diaphragm, ngakolunye uhlangothi, asebenzisa isihlalo esifana nesihlalo sokuvala ivalve.Lolu hlobo luvame ukutholakala kumapayipi asebenza ngemidiya egqwalayo.

Ivalvu yokulawula ukunyakaza inomzila wokugeleza ohleleke kakhudlwana uma kuqhathaniswa nomndeni wokunyakaza omugqa.Ingaphinde ilulame kahle ekwehleni kwengcindezi.Inomthamo wemidiya owengeziwe ngokuguga okuncane ekupakishweni.Ama-valve e-butterfly anikeza ukuvala okuqinile kanye nokwehla kwengcindezi ephansi.

Control Valve Working Mechanism

Njengoba kushiwo ngaphambili, ama-valve okulawula avame ukusetshenziselwa ukulawula ukuhamba kwemidiya.Esinye sezizathu zokuthi kungani lokhu kufanele kwenziwe kukhona ushintsho emthwalweni wengcindezi.Imvamisa, kuba khona inzwa eyethusa uhlelo lwezinguquko eziguquguqukayo zesistimu.Ngemva kwalokho, isilawuli sithumela isignali ku-valve yokulawula, esebenza njengemisipha, ngaleyo ndlela, ilawula ukugeleza njengoba kubonakala esithombeni esingezansi:

Yini amaFlanges?

Ama-flange angamalunga axhuma ama-valve, amaphampu nokunye okunjalo ohlelweni lwamapayipi.Ukuvala uphawu kwenziwa ngamabholithi noma ama-welds ane-gasket phakathi.Ukuthembeka kwama-flange kuncike enqubweni yokwenza ngokuhlanganyela ngokuhambisana nokuguquguquka kwesistimu.

Ngaphandle kwe-welding flanges yizindlela ezivame kakhulu zokujoyina ohlelweni lwamapayipi.Inzuzo yama-flanges ukuthi ivumela ukudilizwa kwe-valve, ngisho nangaphandle kokukhipha izingxenye eziyinhloko ze-valve.
Ngokuvamile, ama-flange anento efanayo nomzimba we-valve noma ipayipi.Izinto ezivame kakhulu zama-flange yinsimbi ye-carbon steel.Ezinye izinto ezisetshenziswayo zibalwe ngezansi”

Iyini i-Flanged Gate Control Valve?

I-valve yesango ene-flanged wuhlobo lwe-valve yesango eneziphetho ezine-flanged.Lolu wuhlobo lwevalvu enomsebenzi ongaphezu kowodwa.Lokhu kungasebenza njenge-valve yokuhlukanisa kanye ne-valve edonsayo.

Njengoba i-valve yesango, iyonga ngenxa yomklamo wayo.Ngaphezu kwalokho, i-valve yokulawula isango ene-flanged ingavuleka noma ivaleke ngokuqinile futhi ngeke ilahlekelwe ukwehla kokucindezela okukhulu ukuze izinga lokugeleza libe nezinguquko ezincane kuphela.
Inamathisela i-actuator kanye nomtshina we-remote pressure drop, i-valve yesango iba ivalvu yokulawula.Nge-disc yayo, ingakwazi ukudonsa ngezinga elithile.

Ukuze i-valve ixhunywe epayipini, ama-flanges kudingeka aboshwe futhi ashiselwe ukuze avikeleke.I-valve yesango ene-flanged ilandela izindinganiso ze-ASME B16.5.Ngokuvamile, lo mklamo usebenzisa i-disc yohlobo lwe-wedge njengento yokuvala.
Lolu hlobo lwe-valve lusetshenziswa ekucindezelweni okuphansi nasekusetshenzisweni kwezinga lokushisa.Ukuba nezimfanelo ze-valve yesango, izinzuzo ze-valve yesango eline-flanged ukuthi ayinawo amaconsi aphezulu okucindezela.

Izicelo ze-Flanged Gate Control Valve

Ama-valve okulawula isango ane-Flanged avame ukusetshenziswa kulezi zicelo ezilandelayo.

# Izicelo zikawoyela ezijwayelekile
# Izicelo Zegesi Namanzi

Ngokufigqiwe

Njengoba kunezigaba eziningi zama-valve, kungenzeka kakhulu ukuthi kunezindlela eziningi zokwenza ama-valve ezinhlelo zokusebenza ezithile.Esinye salezo zibonelo yi-valve yokulawula isango eline-flanged.Le valve isebenza kokubili njenge-valve yokulawula kanye ne-valve yokuvala.Uma ungathanda ukuba nama-valve enziwe ngokwezifiso zezimboni, xhumana nathi lapha.
