ayini amavalvu omzila: ibhola/isango/ukuhlola/amavalvu omhlaba

Amavalvu Ephayiphizidlala indima ebalulekile ezinhlelweni zamapayipi. Ziyizinhlobo ezahlukene futhi zinemisebenzi ehlukene. Emsebenzini wansuku zonke, sivame ukuzwa amagama ahlukahlukene ama-valve, ngezinye izikhathi aze adideke. Ukuze ngisize wonke umuntu aqonde kangcono ama-valve, ikakhulukazi lawo zinhlobo ezivamile, nginqume ukuhlanganisa umbono jikelele wezinhlobo zama-valve ezivamile. Ngiyethemba ukuthi lolu lwazi lungasiza wonke umuntu. Ake sihlole imfihlakalo yama-valve ndawonye. Ake sifunde ngama-valve amapayipi asetshenziswa njalo.

Okusetshenziswa KaningiAmavalvu Ephayiphiyilezi ezilandelayo

I-valve yebhola

• Incazelo emfushane yesimiso sokusebenza:Ingxenye eyinhloko yevalvu yebhola iyindilinga enembobo. Isimiso sayo sokusebenza sisekelwe ekujikelezeni kwale ndilinga ukulawula ukuvulwa nokucinywa koketshezi. Vele ujikelezise ama-degree angu-90, beseivalvu yebholaingafinyelela ekushintsheni okuvulekile noma okuvaliwe ngokuphelele, okulula futhi okusheshayo ukusebenza.
• Izici:Ukusebenza kahle kakhulu kokuvala, ukusebenza okulula, ukumelana noketshezi okuphansi, isakhiwo esiqondakala kalula nesiqondakala kalula, kulula ukusivula nokuvala ngokushesha.
• Isimo sohlelo lokusebenza:Ivame ukusetshenziswa ekuhlanzweni kwamanzi, kumakhemikhali kaphethiloli, ekuthuthweni kwegesi yemvelo nakwezinye izikhathi, ifaneleka kakhulu ezidingweni zezinhlelo zokulawula ezizenzakalelayo.

Amavalvu esango

• Isimiso sokusebenza:Le valve ilawula ukugeleza koketshezi ngokuphakamisa isango, elifanele kakhulu izimo zokusebenza ezivulekile noma ezivalwe ngokuphelele, kodwa alifaneleki ngezikhathi ezidinga ukulungiswa okunembile kokugeleza.
• Izici:Ivalvu yesango isebenza kahle ekuvaleni, kodwa kuthatha isikhathi eside ukuyishintsha, futhi ayifanele ukusetshenziswa njalo.
• Izimo zohlelo lokusebenza:Isetshenziswa kakhulu emipayipini emikhulu, enomfutho ophezulu ukuze inqume ngokuphelele uketshezi olufana namanzi, umusi, uwoyela kanye negesi yemvelo.

I-valve yebhabhathane

• Isimiso sokusebenza:Isakhiwo sevalvu yebhabhathane senzelwe ukuba sibe sincane kakhulu, sibe nosayizi omncane kanye nesisindo esincane. Sifinyelela ukulungiswa okunembile kokugeleza noma ukunqanyulwa koketshezi okuphumelelayo ngokujikeleza ipuleti lebhabhathane.
• Izici:Iyavuleka futhi ivale ngokushesha, kodwa ukuvala kubuthakathaka.
• Izimo zohlelo lokusebenza:Ifaneleka kakhulu ezinhlelweni zamapayipi amakhulu, anomfutho ophansi, njengokuhlinzekwa kwamanzi kanye nokudonswa kwamanzi, ukujikeleza kwamanzi okupholisa kanye neminye imikhakha.

I-valve yeglobe

• Isimiso sokusebenza: Ngokujikelezisa isondo lesandla, idiski yevalvu iqhutshwa ukuze ihambe phezulu naphansi, ngaleyo ndlela kufezwe ukulawulwa okunembile koketshezi. Lo mklamo ufaneleka kakhulu ngezikhathi ezidinga ukulungiswa kokugeleza kanye nokusebenza njalo.
• Izici:Ukusebenza kahle kakhulu kokuvala, ukuvulwa nokuvalwa okusheshayo, kodwa ukumelana noketshezi okukhulu, isakhiwo esiyinkimbinkimbi, okuholela ekulahlekelweni kwengcindezi ephezulu.
• Isicelo:Ifaneleka kakhulu ezimweni zezimboni ezidinga ukulawulwa kokugeleza kwamanzi, njengama-boiler, izinhlelo ze-HVAC, namapayipi omusi.

I-valve yokuhlola

• Isimiso sokusebenza:Iyingxenye yesigaba se-valve ezenzakalelayo, evimbela ukugeleza emuva kwe-medium futhi ivikele ipayipi ekulimaleni ngenxa yomphumela we-water hammer. Ibizwa nangokuthi i-check valve, i-one-way valve, i-reflux valve noma i-isolation valve. Imodi yokuhamba kwe-valve disc ihlukaniswe ngohlobo lokuphakamisa kanye nohlobo lwe-swing.
• Izici:Umsebenzi walolu hlobo lwe-valve ukuvumela i-medium ukuthi igeleze ohlangothini olulodwa kuphela futhi ivimbele ukugeleza kolunye uhlangothi. Kuyingxenye ebalulekile yokuqinisekisa ukuphepha kohlelo.
• Isimo sohlelo lokusebenza:Ivame ukusetshenziswa emishinini efana nama-boilers kanye nemithambo yokucindezela, i-check valve isetshenziswa kanye ne-stop valve ukuze idlale indima ekuhlukaniseni ukuphepha.

I-valve yokusiza ukucindezeleka

• Isimiso sokusebenza:Uma ingcindezi yesistimu idlula umkhawulo ohleliwe, ivalvu yokuphepha izoqala ngokuzenzakalelayo ukukhulula ingcindezi eyeqile ukuqinisekisa ukuthi imishini kanye nesistimu akulimazwa yingcindezi eyeqile. Uma ingcindezi yehle yabuyela endaweni ephephile, ivalvu izovala ngokuzenzakalelayo bese ibuyela esimweni sayo esijwayelekile.
• Izici: Ukukhululeka ekucindezelekeniAma-valve aziwa ngokuzwela kwawo okuphezulu. Angasabela ngokushesha nangokuzenzakalela ezinguqukweni zokucindezela ohlelweni, avimbele ngempumelelo ukucindezela kohlelo ukuthi kudlule izinga, ngaleyo ndlela aqinisekise ukusebenza okuphephile kwemishini.
• Izimo zohlelo lokusebenza:Amavalvu okuphepha asetshenziswa kabanzi emkhakheni wokuvikela ukucindezela ngokweqile kwemishini efana nama-boiler, imikhumbi yokucindezela, kanye nezinhlelo zamapayipi, futhi ayimishini yokuphepha ebaluleke kakhulu.

Ivalvu yensimbi (ivalvu yenaliti)

• Isimiso sokusebenza:Ngokujikelezisa isondo lesandla, umongo wevalvu yenaliti ungaqhutshwa ukuze uye phezulu naphansi, ngaleyo ndlela kufezwe ukulawulwa okunembile nokulawulwa kokugeleza koketshezi.
• Izici:Inokulawula ukugeleza okunembile kanye nokuvala okuhle, futhi ifaneleka kakhulu ezinhlelweni zokucindezela okuphezulu kanye nokugeleza okuncane, kodwa isivinini sokuvula nokuvala sihamba kancane.
• Izimo zohlelo lokusebenza:Ama-valve e-plug asetshenziswa kabanzi emishinini yelabhorethri, ezinhlelweni zokulawula igesi noma uketshezi, kanye nokulawula umfutho ophezulu kanye nokugeleza okuncane.

I-plug valve

• Incazelo yesimiso sokusebenza:I-valve yepulaki ilungisa indawo ehlobene yesiteshi sepulaki kanye nepayipi ngokujikeleza ipulaki eliyisilinda noma eliyindilinga ukuze kufezwe ukulawula kokuvula nokuvala koketshezi.
• Izici:I-valve yepulagi inesakhiwo esincane, kulula ukuyisebenzisa, futhi inokuvula nokuvala okusheshayo, okulungele kakhulu izikhathi ezidinga ukushintsha njalo.
• Izindawo zokufaka isicelo:Idlala indima ebalulekile ezinhlelweni zamapayipi ezimboni zegesi yemvelo, uphethiloli kanye namakhemikhali, futhi isetshenziswa kabanzi ekulawuleni uketshezi kulezi zinsimu.

I-valve ye-solenoid

• Isimiso sokusebenza:Ku-valve ye-solenoid, ukuvulwa nokuvalwa kwekhoyili ye-electromagnetic kuzobangela izinguquko emandleni kagesi, okuzobe sekuqhuba ukunyakaza kwe-valve core ukuvula noma ukuvala i-valve. Uma i-coil ye-electromagnetic ingasebenzi, i-valve core izoqala kabusha futhi i-valve izovala.
• Izici:I-valve yepulagi iphendula ngokushesha futhi isekela ukulawula okukude, okwenza ifaneleke kakhulu ukusetshenziswa ezinhlelweni zokwenza izinto ngokuzenzakalela.
• Izimo zohlelo lokusebenza:Idlala indima ebalulekile ezinhlelweni zokulawula okuzenzakalelayo, isibonelo, ekulawuleni okuzenzakalelayo kokuvula nokuvala kwamapayipi amanzi, igesi kanye namafutha. Kodwa-ke, kunezinhlobo eziningi zamavalvu, okungaphezu nje kwamavalvu epulaki.

IIsifinyezo

Amavalvu ephayiphi ayizingxenye zokulawula ezinhlelweni zokulethwa koketshezi lwamaphayiphi, anemisebenzi efana nokuvala, ukulawula, ukuphambukisa, ukuvimbela ukugeleza emuva, ukuzinzisa ingcindezi, ukuphambukisa ukugeleza noma ukukhulula ingcindezi yokugcwala. Amavalvu asetshenziswa ezinhlelweni zokulawula uketshezi anezinhlobonhlobo eziningi zezinhlobo kanye nemininingwane.
