Ngokuya ngezinto zokubekwa uphawu, i-valve yembulunga ingahlukaniswa ngezigaba ezimbili: i-valve yokuvala uphawu lomhlaba ethambile kanye nensimbi yokuvala uphawu lwembulunga Ngokusho kwesakhiwo sediski kungahlukaniswa ngezigaba ezimbili: i-disc iglobhu ye-glove elinganisiwe ne-disc engalinganiseli i-globe valve; Ngokwefomu lokugeleza kwesiteshi lingahlukaniswa libe yisiteshi se-DC, isiteshi se-Z, isiteshi se-Angle, isiteshi se-DC neziteshi ezintathu, njll.
Uphawu Soft imbulunga valve
Ku-valve yembulunga, ukuvikela ukuthi izimvu zamanzi ezithambile zingalimali ngenxa yokushisa, kufakwa insimbi ekhipha imisebe phambi kwezimpawu zamanzi ezithambile, ezakhiwa yishidi lensimbi elinendawo enkulu ekhanyayo. Endabeni yesevisi yomoya-mpilo, lo mklamo awenele ukuvimbela umlilo wezimpawu ezithambile. Ukuvimbela ukwehluleka kwale valve, indawo yokungena engaphandle kwesihlalo se-valve kufanele inwetshwe ukuze umkhawulo owodwa wepaseji engenayo wakhe isikhwama ukuze igesi elishisayo liqoqele kude nophawu. Ekudizayineni kobuso obuthambile, kubalulekile ukuthi ucabangele ukuvimbela into yokufaka uphawu ethambile ukuthi ingakhishwa noma ibangelwe ukufuduswa kwengcindezi ephakathi.
Izinto zokuvala uphawu ezithambile zifaka ama-disc-clad disc, i-PTFE (noma ezinye izihlalo zepulasitiki) noma amadiski wensimbi afakwe ngezinto ezingekho emthethweni, kanye nokwakhiwa kwediski lokuvala uphawu okuqinile okunzima futhi okuthambile. Lolu hlobo lwe-valve yesembozo esithambile luvame ukusetshenziswa emithonjeni yezindaba ye-steam negesi, ikakhulukazi kuma-valve wokuhlola okugcina ingcindezi. Amandla okuvala adingwa yi-valve yesembozo esithambile mancane ngokwedlulele, futhi kulula ukungena esikhundleni sediski yesithambile. Uma nje indawo yokufaka uphawu esihlalweni se-valve ingalimalanga, ukushintshwa kophawu oluthambile lwediski ye-valve kungekudala kuzobuyisela ukusebenza kwe-valve.
1. Idiski embozwe nge-raber soft seal glove valve
Yize umzimba we-valve usebenzisa isakhiwo esimise okwe-T, kepha ku-valve body cavity inlet isiteshi ohlangothini lokuphonsa nokuqondisa okuvundlile kwesihlalo se-45 °, okwenza ukuthi ishaneli le-valve lihambisane, ukufeza umphumela ofanayo nomzimba we-valve oqonde ngqo, ophakathi umthamo wokugeleza muhle; Futhi ngenxa yokusetshenziswa kophawu lwenjoloba oluthambile, ukusebenza kokufakwa uphawu kwe-valve kuhle.
Igobolondo le-valve lenziwe ngensimbi yensimbi kanti idiski ye-valve imbozwe nge-EPDM.
I-valve inezici ezilandelayo:
FreeAkulondolozwa;
ResistanceLow ukugeleza ukumelana, uketshezi okuhle;
HUkuqhuqha umsebenzi;
Idizayini yenduku emnyama (ukukhushulwa kwangaphakathi kwentambo);
Imicu yesiqu emzimbeni we-valve ngaphandle;
RomKusuka esikhungweni se-valve stem;
SealEDD uphawu lwesifutho;
ProtectionUkuvikela ukubekwa uphawu okubili;
CoverIsembozo sokufakwa emgodini sinomsebenzi wokuvikela ukufingqa ngasikhathi sinye;
Umzimba we-valve obonakalayo ungavinjelwa ngokuphelele, ungonga amandla.
Ivelufa isetshenziselwa kakhulu uhlelo lwamanzi ashisayo ayi-10 ~ 120C, ukufudumeza
Uhlelo nesistimu yokungenisa umoya.
2. I-valve yokuvala uphawu ethambile engeyona insimbi
I-valve yensimbi ethambile yokumboza ethambile iboshwe nge-polytetrafluoroethylene namanye ama-polymers kudiski, asetshenziswa kakhulu ohlelweni lwamapayipi kagesi esiteshini segesi esenziwe ngophethiloli.
