Amavalvu okuhlola i-waferaziwa nangokuthi ama-valve okugeleza emuva, ama-valve okumisa emuva, kanye nama-valve okucindezela emuva. Lolu hlobo lwama-valve luvulwa futhi luvalwe ngokuzenzakalelayo ngamandla akhiqizwa ukugeleza kwe-medium uqobo epayipini, okungohlobo lwe-valve ezenzakalelayo.
I-valve yokuhlola incike ekugelezeni kwe-medium ngokwayo futhi ivule futhi ivale ngokuzenzakalelayo i-valve flap, esetshenziselwa ukuvimbela i-valve yokubuyela emuva ephakathi, eyaziwa nangokuthi i-valve yokuhlola, i-valve yokuhlola, i-valve yokubuyela emuva, kanye ne-valve yokucindezela emuva. I-valve yokuhlola ingeyehlobo lwe-valve ezenzakalelayo, indima yayo eyinhloko ukuvimbela ukubuyela emuva kwe-media, ukuvimbela ipompo kanye ne-drive motor reverse, kanye nokukhishwa kwe-container media. Ama-valve okuhlola angasetshenziswa futhi ukunikeza ingcindezi ingakhuphuka ibe ngaphezu kwengcindezi yesistimu yesistimu yokusiza ukuze inikeze ipayipi lokuhlinzeka. I-valve yokuhlola ingahlukaniswa ibe yi-valve yokuhlola i-swing (ngokuya ngesikhungo sokujikeleza kwamandla adonsela phansi) kanye ne-valve yokuhlola i-lift (ehamba nge-axis).
Okokuqala, ukusetshenziswa kwe-clip-on check valve check valve efakwe ohlelweni lwamapayipi, indima yalo eyinhloko ukuvimbela ukubuyela emuva kwe-media, i-check valve iwuhlobo lwe-valve ezenzakalelayo ethembele ekucindezelweni kwe-media ukuze ivuleke futhi ivalwe. I-clamp check valve ifanelekela ingcindezi ejwayelekile ye-PN1.0MPa ~ 42.0MPa, i-Class150 ~ 25000, ububanzi obujwayelekile be-DN15 ~ 1200mm, i-NPS1/2 ~ 48, izinga lokushisa lokusebenza -196 ~ 540 ℃ yamapayipi ahlukahlukene, asetshenziselwa ukuvimbela ukubuyela emuva kwe-media. Ngokukhetha izinto ezahlukene, ingasetshenziswa emanzini, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidizing media enamandla kanye ne-uric acid kanye nezinye izinto.
Izinto eziyinhloko zevalvu yokuhlola i-wafer yinsimbi yekhabhoni, insimbi ephansi lokushisa, insimbi ye-duplex (SS2205/SS2507), i-titanium alloy, ithusi le-aluminium, i-Inconel, i-SS304, i-SS304L, i-SS316, i-SS316L, insimbi ye-chrome-molybdenum, i-Monel (400/500), i-20# alloy, i-Hastelloy nezinye izinto zensimbi.
Okwesithathu, amazinga kanye nezindinganiso ze-valve yokuhlola i-wafer
Umklamo: API594, API6D, JB/T89372,
Ubude bobuso nobuso：API594、API6D、DIN3202、JB/T89373、
Izinga lokucindezela kanye nokushisa：ANSI B16.34、DIN2401、GB/T9124、HG20604、HG20625、SH3406、JB/T744、
Izinga lokuhlola nokuhlola: API598, JB/T90925
Ama-Flanges Okufaka Amapayipi：JB/T74~90、GB/T9112-9124、HG20592~20635、SH3406、ANSI B 16.5、DIN2543-2548、GB/T13402、API605、ASMEB16.47
Okwesine, izici zesakhiwo se-pinch check valve
1. Ubude besakhiwo esifushane, ubude besakhiwo saso buyi-1/4 ~ 1/8 kuphela yevalvu yokuhlola i-swing flange yendabuko.
2. ivolumu encane, isisindo esincane, isisindo sayo siwukuphela kwe-flange check valve yendabuko 1/4 ~ 1/2
3. i-valve flap ivala ngokushesha, umfutho wesando samanzi mncane
4. Kungasetshenziswa amapayipi avundlile noma aqondile, kulula ukuwafaka
5. Indlela yokugeleza ebushelelezi, ukumelana noketshezi oluphansi
6. Isenzo esibucayi, ukusebenza kahle kokuvala
7. Ukushaya kwediski kufushane, umthelela wokuvala mncane
8. Isakhiwo sisonke silula futhi sincane, futhi ukuma kwaso kuhle
9. Impilo yenkonzo ende kanye nokusebenza okuthembekile
5. Ukusebenza kokuvala kwevalvu yokuhlola i-wafer Ivalvu yokuhlola i-wafer evaliwe kahle ingafinyelela ukuvuza okungekho, kodwa ivalvu yokuhlola i-wafer evaliwe kanzima akuyona ivalvu engavuzi lutho. Inezinga elithile lokuvuza. Ngokwezinga lokuhlola le-API598, levalvu yokuhlola enesihlalo sensimbi, ngobukhulu be-DN100, izinga lokuvuza koketshezi ngomzuzu lingu-12CC.
