Yiziphi izigaba zama-valve okuhlola?

Njengesisetshenziswa esibalulekile sokuvimbela ukubuyela emuva okumaphakathi,hlola ama-valveasetshenziswa kakhulu ezinhlelweni zamapayipi. Ngokwezakhiwo ezahlukene kanye nezimiso zokusebenza, ama-valve okuhlola ahlukaniswe ikakhulukazi ngezigaba ezilandelayo:

1. I-valve yokuhlola i-Swing

I-valve yokuhlola i-rotary ivula futhi ivale ngokuzungezisa i-valve disc ezungeze i-eksisi engaguquki. Lapho i-medium igeleza phambili, i-valve disc iphushwa ivuleke; Lapho uhlehla, idiski ye-valve ivala ngaphansi kwesisindo sayo kanye namandla okusabela we-medium. Izinzuzo zayo ziwukumelana nokugeleza okuphansi, ukuvulwa nokuvala ngokushesha, kufanelekile kububanzi obukhulu, izimo zesilinganiso sokugeleza okuphansi njengezindawo zokupompa noma amapayipi avundlile. Nokho, umphumela wesando samanzi ungenzeka ngesikhathi sokugeleza kwesivinini esikhulu, futhi idivayisi yebhafa iyadingeka.

2. Phakamisa i-valve yokuhlola

I-disc ye-valve ye-lifthlola i-valveihamba nge-eksisi eqondile ye-valve yomzimba. Uma ugeleza phambili, ukucindezela okuphakathi kuphusha i-valve disc phezulu; Lapho uhlehla, i-disc ye-valve iwela ngaphansi kwesenzo samandla adonsela phansi noma entwasahlobo, inqamula okuphakathi. Lolu hlobo lwe-valve yokuhlola lunomsebenzi omuhle wokuvala, kodwa ukumelana nokugeleza okuphezulu, futhi lusetshenziswa kakhulu ku-caliber encane, ukucindezela okuphezulu, noma izinhlelo zokusebenza ezifakwe ziqondile, njengezinhlelo ze-steam.

3. I-valve yokuhlola i-Butterfly

I-valve yokuhlola i-Butterfly ihlanganisa izici zamavalvu e-rotary kanye ne-butterfly, ne-disc eyindilinga ezungeza i-axis emaphakathi. Inesakhiwo esihlangene nesisindo esilula, esilungele amapayipi anobubanzi obukhulu kanye nengcindezi ephansi, futhi ivame ukusetshenziswa ekunikezeni amanzi kanye nobunjiniyela be-drainage. Kodwa ukuvala uphawu kubuthakathaka futhi kudinga ukulungiswa njalo.

4. I-valve yokuhlola i-diaphragm

Ama-valve okuhlola ama-diaphragm asebenzisa ukuguquguquka okunwebekayo kwe-diaphragm yerabha ukulawula ukuvulwa nokuvala. Lapho i-medium igeleza phambili, i-diaphragm yeluliwe ivuleke; Lapho uhlehla, i-diaphragm iphindela emuva ukuze ivale isiteshi. Lolu hlobo lwe-valve yokuhlola alukho ukungqubuzana kwemishini kanye nempilo ende yesevisi, kodwa ukushisa kwalo nokumelana nokucindezela kunqunyelwe, futhi kusetshenziselwa kakhulu ukuhlanza imidiya noma izinhlelo eziphansi zokucindezela.

5. I-valve yokuhlola i-piston

I-valve yokuhlola i-piston ivula futhi ivale ngokusebenzisana kwe-piston ne-spring. Ingcindezi emaphakathi inqoba amandla asentwasahlobo ukuze iphushe i-piston ukuze inyakaze, futhi intwasahlobo iyabuya futhi ivale lapho ihlehla. Inomsebenzi omuhle kakhulu wokubeka uphawu futhi ifanele izinga lokushisa eliphezulu kanye nezindawo zokucindezela okuphezulu, njengemboni ye-petrochemical, kodwa isakhiwo sayo siyinkimbinkimbi futhi izindleko ziphezulu.

Izimo ezisebenzayo zezinhlobo ezahlukene zehlola ama-valvezidinga ukukhethwa ngokuphelele ngokusekelwe ezicini ze-medium, ingcindezi, izinga lokugeleza, nezimo zokufaka ukuqinisekisa ukusebenza okuphephile nokusebenza kahle kwesistimu.
