Umgaqo-siseko wokuSebenza kunye noHlelo lweeValve zokuHlola i-Taike Valve

Ivalve yokujonga: Ivalve yokukhangela, ekwabizwa ngokuba yivalve yendlela enye okanye ivalve yokukhangela, isetyenziselwa ukuthintela okuphakathi kumbhobho ukuba ungabuyeli umva. Ivalve esezantsi yokufunxa nokuvala impompo yamanzi ikwakwinqanaba levalvu yokutshekisha. Ivalve exhomekeke ekuhambeni nasekunyanzeleni okuphakathi ukuzivula okanye ukuzivala, ukuze kuthintelwe i-medium ukuba ingabuyeli ngasemva, ibizwa ngokuba yi-check valve. Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo. Iivalve zokujonga zisetyenziswa ikakhulu kwimibhobho ehamba ngokulinganayo kumajelo eendaba, evumela kuphela ulwalathiso olunye lokuhamba kweendaba ukuthintela iingozi. Iivalve zokujonga zinokwahlulwa zibe ziindidi ezintathu ngokwesakhiwo sazo: iivalve zokujonga ukuphakamisa, iivalve zokujonga ujingi, kunye neevalvu zokujonga ibhabhathane. Iivalve zokujonga ukuphakamisa zinokwahlulwa zibe ziindidi ezimbini: iivalve zokujonga ezithe nkqo kunye neevalvu zokujonga ezithe tye. Iivalvu zokujonga i-Swing zahlulwe zaba ziindidi ezintathu: iivalvu zokujonga idiskhi enye, iivalvu zokujonga iidiski ezimbini, kunye neevalvu zokujonga iidiski ezininzi. Iivalve zetshekhi zebhabhathane zithe tye ngeevalvu zokutshekisha, kwaye ezi ndidi zingentla zeevalvu zetshekhi zinokwahlulwa zibe ziindidi ezintathu ngokwemigaqo yoqhagamshelo: iivalvu zetshekhi ezinemisonto, iivalve zetshekhi zeflange, kunye neevalve ezidityanisiweyo zokujonga.

Ufakelo lweevalvu zokutshekisha kufuneka kuthathelwe ingqalelo le miba ilandelayo:

1. Musa ukuvumela ivalve yokutshekisha ukuba ithwale ubunzima kumbhobho. Iivalve ezinkulu zokujonga kufuneka zixhaswe ngokuzimeleyo ukuze zithintele ukuba zingachatshazelwa luxinzelelo oluveliswa yinkqubo yombhobho.

2. Ngexesha lofakelo, nikela ingqalelo kwindlela yokuhamba okuphakathi ekufuneka ihambelane nesalathiso sotolo oluboniswe kumzimba wevalvu.

3. Uhlobo lokuphakamisa iivalvu zokujonga iidiski ezithe nkqo kufuneka zifakwe kwimibhobho emi nkqo.

4. Uhlobo lokuphakamisa i-valve ye-disc yokujonga i-horizontal kufuneka ifakwe kumbhobho othe tye.

Iiparamitha eziphambili zokusebenza kweevalvu zokutshekisha:

Uxinzelelo lwegama okanye inqanaba loxinzelelo: PN1.0-16.0MPa, ANSI Class150-900, JIS 10-20K, i-diameter yegama okanye ububanzi: DN15 ~ 900, NPS 1/4-36, indlela yokudibanisa: i-flange, i-butt welding, intambo, i-socket ukuwelda, njl., ubushushu obusebenzayo: -196 ℃~540 ℃, imathiriyeli yevalvu yomzimba: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Ngokukhetha izixhobo ezahlukeneyo, i-valve yokutshekisha inokufaneleka kwiimidiya ezahlukeneyo ezifana namanzi, i-steam, ioli, i-nitric acid, i-acetic acid, i-oxidizing media, urea, njl.
