Intshayelelo kwisicelo, izinto eziphambili kunye neempawu zesakhiwo sevalve yokujonga ipleyiti ephindwe kabini

Waferipleyiti ezimbinikhangela ivalveibhekisa kwivalve ezivula ngokuzenzekelayo kwaye ivale isivalo sevalve ngokuthembela ekuhambeni kwesiphakathi ngokwaso ukunqanda ukubuya umva kwendawo, ekwaziwa ngokuba yivalve yokutshekisha, ivelufa yendlela enye, ivalve yokuqukuqela umva kunye nevalve yoxinzelelo yangasemva. Waferipleyiti ezimbinikhangela ivalvei-valve ezenzekelayo umsebenzi wayo oyintloko kukukhusela umva we-medium, ukuthintela ukujikeleza okujikelezayo kwempompo kunye nemoto yokuqhuba, kwaye ukhuphe i-medium kwisitya. Waferipleyiti ezimbiniiivalve zokutshekisha zingasetyenziswa kwimigca yokubonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokuphakama ngaphezu koxinzelelo lwenkqubo.

1. Iwafer yohlobo lwepleyiti yokukhangela ipleyiti yokukhangela isicelo:

Waferipleyiti ezimbinikhangela ivalveifakwe kwisixokelelwano sombhobho, kwaye umsebenzi wayo oyintloko kukuthintela ukubuyela ngasemva kwendawo. Isonka esisicabaipleyiti ezimbinikhangela ivalveyivalve ezenzekelayo evulwayo kwaye ivalwe ngokuxhomekeke kuxinzelelo oluphakathi. Uhlobo lwe-waferipleyiti ezimbinikhangela ivalveilungele uxinzelelo lwegama PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; Idayamitha eqhelekileyo DN15 ~ 1200mm, NPS1/2 ~ 48; ubushushu bokusebenza -196 ~ 540 ℃ kwimibhobho eyahlukeneyo, esetyenziselwa ukuthintela umva we-medium. Ngokukhetha izixhobo ezahlukeneyo, inokuthi isetyenziswe kumajelo ohlukeneyo anjengamanzi, umphunga, ioyile, i-nitric acid, i-acetic acid, i-oxidizing medium kunye ne-uric acid.

2. Izinto eziphambili ze-waferipleyiti ezimbinijonga ivalve:

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 seipleyiti ezimbinijonga ivalve:

1. Ubude besakhiwo bufutshane, kwaye ubude bayo besakhiwo buyi-1/4 ~ 1/8 kuphela ye-flanged yendabuko.jingikhangela ivalve.

2. Ubungakanani obuncinci kunye nobunzima obulula, ubunzima bayo buyi-1/4 ~ 1/20 kuphela ye-flanged yendabuko.jingikhangela ivalve.

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 ancinci

8. Isakhiwo esipheleleyo silula kwaye sincinci, kwaye imilo ihle

9. Ubomi benkonzo ende kunye nokusebenza okuthembekileyo

Okwesine, iimpazamo eziqhelekileyo zeipleyiti ezimbiniitshekhi valve zezi:

1. Idiskhi yevalve yaphukile

Uxinzelelo lwe medium phambi nasemvaipleyiti ezimbinikhangela ivalveikwimeko yolungelelwaniso olusondeleyo kunye ne "saw" efanayo. I-disc yevalve isoloko ibethelwa ngesitulo sevalve, kwaye idiski yevalve eyenziwe ngezinto ezinqabileyo (ezifana nentsimbi etyhidiweyo, ubhedu, njl.njl.) iyabethwa. yaphukile.

Indlela yokuthintela kukusebenzisa aipleyiti ezimbinikhangela i-valve ene-disc njengesixhobo se-ductile.

2. Ukubuyela umva okuphakathi

Umphezulu wokutywina wonakaliswe; ukungcola kubanjisiwe.

Ngokulungisa indawo yokutywina kunye nokucoca ukungcola, ukubuyisela umva kunokuthintelwa.
