Khangela ivalveibhekisa kwivalve ezivula ngokuzenzekelayo kwaye ivale isivalo sevalve ngokuthembela ekuhambeni kwendawo ephakathi ngokwayo ukunqanda ukubuya umva kwendawo, ekwaziwa ngokuba yivalve yokutshekisha, ivalve yendlela enye, ivelufa yokuqukuqela umva kunye ivelufa yoxinzelelo lwangasemva.I-valve yokukhangela i-valve ezenzekelayo umsebenzi wayo oyintloko kukukhusela umva we-medium, ukujikeleza okujikelezayo kwempompo kunye ne-motor yokuqhuba, kunye nokukhutshwa kwe-container medium.Iivalvu zokutshekisha zingasetyenziswa kwimigca ebonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokunyuka ngaphezu koxinzelelo lwenkqubo.
1. Ukusetyenziswa kwevalve yewafer:
I-valve yokutshekisha ifakwe kwi-system yepayipi, kwaye umsebenzi wayo oyintloko kukuthintela ukubuya kwe-medium.I-valve yokukhangela i-valve ezenzekelayo evuliwe kwaye ivaliwe ngokuxhomekeke kuxinzelelo lwe-medium.Ivalve yokujonga i-waferilungele uxinzelelo lwegama PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;Idayamitha eqhelekileyo DN15 ~ 1200mm, NPS1/2 ~ 48;ubushushu bokusebenza -196 ~ 540 ℃ kwimibhobho eyahlukeneyo, esetyenziselwa ukuthintela ukubuya 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.
Okwesibini, izinto eziphambili zevalve yokujonga i-wafer:
Kukho intsimbi ekhatywayo, intsimbi ye-carbon, intsimbi ephantsi yobushushu, intsimbi ye-dual phase (F51 / F55), i-titanium alloy, i-aluminium bronze, i-INCONEL, i-stainless steel SS304, i-SS304L, i-SS316, i-SS316L, i-chrome molybdenum steel, i-Monel (400/500), 20 # i-alloy, i-Hastelloy kunye nezinye izinto zetsimbi.
3. Iimpawu zesakhiwo sevalve yokujonga i-wafer:
1. Ubude bolwakhiwo bufutshane, kwaye ubude bayo besakhiwo buyi-1/4 ~ 1/8 kuphela yevalve yokukhangela iflange.
2. Ubungakanani obuncinci kunye nobunzima obulula, ubunzima bayo buyi-1/4 ~ 1/20 kuphela yevalve yokukhangela iflange.
3. I-disc ye-valve ivala ngokukhawuleza kwaye uxinzelelo lwehamile yamanzi luncinci
4. Zombini iipayipi ezinqamlekileyo okanye iipayipi ezinqamlekileyo zingasetyenziswa, kulula ukuyifaka
5. Umjelo wokuhamba ulungile kwaye ukuxhathisa ulwelo kuncinci
6. Isenzo esibucayi kunye nokusebenza kakuhle kokutywinwa
7. Uhambo lwediski yevalve lufutshane kwaye amandla empembelelo yokuvala incinci
8. Isakhiwo esipheleleyo silula kwaye sincinci, kwaye imilo ihle
9. Ubomi benkonzo ende kunye nokusebenza okuthembekileyo
Okwesine, iimpazamo eziqhelekileyo zevalve yokutshekisha zezi:
1. Idiskhi yevalve yaphukile
Uxinzelelo lwe-medium ngaphambi nangemva kokuba i-valve yokutshekisha ikwimeko yokulinganisa okusondeleyo kunye ne "saw" ehlangeneyo.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.
2. Ukubuyela umva okuphakathi
Umphezulu wokutywina wonakaliswe;ukungcola kubanjisiwe.Ngokulungisa indawo yokutywina kunye nokucoca ukungcola, ukubuyisela umva kunokuthintelwa.
