Khangela ivalve ibhekisa kwivalve evula ngokuzenzekelayo kwaye ivale i-flap yevalve ngokuthembela ekuhambeni kwendawo ephakathi ngokwayo ukunqanda ukubuya umva kwesiphakathi, esikwaziwa ngokubakhangela ivalve, ivalve yendlela enye, ivelufa yokubuyela umva kunye nevalve yoxinzelelo lwangasemva. Ikhangela ivalvei-valve ezenzekelayo umsebenzi wayo oyintloko kukuthintela umva we-medium, ukujikeleza umva kwempompo kunye ne-motor yokuqhuba, kunye nokukhutshwa kwe-medium kwi-container. Iivalvu zokutshekisha zingasetyenziswa kwimigca ebonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokunyuka ngaphezu koxinzelelo lwenkqubo.
1.Tusebenzisa ivalve yokujonga iwafer:
Ikhangela ivalve ifakwe kwisixokelelwano sombhobho, kwaye umsebenzi wayo oyintloko kukuthintela ukubuyela ngasemva kwendawo. Ikhangela ivalveyivalve ezenzekelayo evulwayo kwaye ivalwe ngokuxhomekeke kuxinzelelo oluphakathi.Ivalve yokujonga i-wafer ilungele uxinzelelo lwegama PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; Idayamitha eqhelekileyo DN15 ~ 1200mm, NPS1/2 ~ 48; Ukubuyela umva okuphakathi. Ngokukhetha izixhobo ezahlukeneyo, inokuthi isetyenziswe kumajelo ohlukeneyo anjengamanzi, umphunga, ioyile, i-nitric acid, i-acetic acid, i-oxidizing medium kunye ne-uric acid.
2.Tizinto eziphambili zeivalve yokujonga iwafer:
Kukho intsimbi yekhabhoni, intsimbi ephantsi yobushushu, intsimbi yenqanaba ezimbini (F51/F55), ingxubevange yetitanium, ubhedu lwe-aluminium, i-INCONEL, SS304, SS304L, SS316, SS316L, intsimbi ye-chrome molybdenum, iMonel (400/500), 20# ingxubevange, i-Hastelloy kunye nezinye izinto zentsimbi.
3. Iimpawu zesakhiwo seivalve yokujonga iwafer:
A. Ubude bolwakhiwo bufutshane, kwaye ubude bayo besakhiwo buyi-1/4 ~ 1/8 kuphela yevalve yokujonga iflange.
B. Ubungakanani obuncinci kunye nobunzima obulula, ubunzima bayo buyi-1/4 ~ 1/20 kuphela yevalve yokukhangela i-flange
C. I-disc ye-valve ivala ngokukhawuleza kwaye uxinzelelo lwehamile yamanzi luncinci
D. Zombini imibhobho ethe tyaba okanye imibhobho ethe nkqo ingasetyenziswa, kulula ukuyifaka
E. Umjelo wokuhamba ugudile kwaye ukuxhathisa ulwelo kuncinci
F. Isenzo esibuthathaka kunye nokusebenza kakuhle kokutywinwa
G. I-valve disc yokuhamba ifutshane kwaye amandla okuvala impembelelo encinci
H. Isakhiwo esipheleleyo silula kwaye sihlangene, kwaye imilo ihle
I. Ubomi benkonzo ende kunye nokusebenza okuthembekileyo
4.Tiimpazamo eziqhelekileyo zevalve yokukhangela zezi:
A. Idiskhi yevalve yaphukile
Uxinzelelo lwe-medium ngaphambi nangemva kokuba i-valve yokutshekisha ikwimeko esondeleyo kwi-balance and mutual "saw". Idiskhi yevalve isoloko ibethwa ngesitulo sevalve, kwaye idiskhi yevalve eyenziwe ngezinto ezibhityileyo (ezifana nentsimbi etyhidiweyo, ubhedu, njl.njl.) yophukile. Indlela yokukhusela kukusebenzisa i-valve yokutshekisha nge-disc njengento ye-ductile.
B. Ukubuyela umva okuphakathi
Umphezulu wokutywina wonakaliswe; ukungcola kubanjisiwe. Ngokulungisa indawo yokutywina kunye nokucoca ukungcola, ukubuyisela umva kunokuthintelwa.
