Intshayelelo kusetyenziso, izinto eziphambili kunye neempawu zesakhiwo sevalvu yokujonga i-wafer

Ivalvu yokujonga ibhekisa kwivalvu evula ize ivale ngokuzenzekelayo i-valve flap ngokuxhomekeka ekuhambeni kwe-medium ngokwayo ukuthintela ukubuyela umva kwe-medium, eyaziwa ngokuba yiivalvu yokujonga, ivalvu yendlela enye, ivalvu yokuhamba umva kunye nevalvu yoxinzelelo lomqolo.ivalvu yokujongayivalvu ezenzekelayo enomsebenzi wayo oyintloko kukuthintela ukubuya komoya ophakathi, ukujikeleza okungasemva kwepompo kunye nemoto eqhubayo, kunye nokukhutshwa komoya ophakathi kwisikhongozeli. Iivalvu zokujonga zingasetyenziswa nakwiimigca ezibonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokunyuka ngaphezu koxinzelelo lwenkqubo.

1.Tukusebenzisa ivalvu yokujonga i-wafer:

Iivalvu yokujonga ifakelwe kwinkqubo yemibhobho, kwaye umsebenzi wayo ophambili kukuthintela ukubuya kwamanzi kwi-medium.ivalvu yokujongayivalvu ezenzekelayo evulwa kwaye ivalwe ngokuxhomekeke kuxinzelelo oluphakathi.Ivalvu yokujonga i-wafer ifanelekile kwi-nominal pressure PN1.0MPa~42.0MPa, Class150~25000; nominal diameter DN15~1200mm, NPS1/2~48; Medium backflow. Ngokukhetha izinto ezahlukeneyo, ingafakwa kwiindawo ezahlukeneyo ezifana namanzi, umphunga, ioyile, i-nitric acid, i-acetic acid, i-oxidizing medium enamandla kunye ne-uric acid.

2.Tizinto eziphambili zeivalvu yokujonga i-wafer:

Kukho intsimbi yekhabhoni, intsimbi enobushushu obuphantsi, intsimbi yesigaba esiphindwe kabini (F51/F55), i-titanium alloy, i-aluminium bronze, i-INCONEL, i-SS304, i-SS304L, i-SS316, i-SS316L, intsimbi ye-chrome molybdenum, i-Monel (400/500), i-20# alloy, i-Hastelloy kunye nezinye izinto zesinyithi.

3. Iimpawu zesakhiwo seivalvu yokujonga i-wafer:

AUbude besakhiwo bufutshane, kwaye ubude besakhiwo buyi-1/4 ~ 1/8 kuphela yevalvu yokujonga iflange yendabuko.

B. Ubukhulu bayo buncinci kwaye bulula, ubunzima bayo buyi-1/4 ~ 1/20 kuphela yevalvu yokujonga iflange yendabuko

CIdiski yevalvu ivala ngokukhawuleza kwaye uxinzelelo lwesando samanzi luncinci

DZombini iipayipi ezithe tye okanye ezithe nkqo zingasetyenziswa, kulula ukuzifaka

EUmjelo wokuhamba uthambile kwaye ukumelana kolwelo kuncinci

FIsenzo esinobuzaza kunye nokusebenza kakuhle kokutywina

GUkuhamba kwediski yevalvu kufutshane kwaye amandla okuvala amancinci

HIsakhiwo siphela silula kwaye sincinci, kwaye imilo yaso intle

IUbomi benkonzo ende kunye nokusebenza okuthembekileyo

4.TIimpazamo eziqhelekileyo zevalvu yokujonga zezi:

AIdiski yevalvu yaphukile

Uxinzelelo lwesixhobo ngaphambi nasemva kwevalvu yokukhangela lukwimeko yokulingana kunye "nesarha" efanayo. Idiski yevalvu idla ngokubethwa ngesitulo sevalvu, kwaye idiski yevalvu eyenziwe ngezinto ezibuthathaka (ezifana nentsimbi ephosiweyo, ubhedu, njl.njl.) iyaphuka. Indlela yokuthintela kukusebenzisa ivalvu yokukhangela enediski njengesixhobo esithambileyo.

B. Ukubuyela umva okuphakathi

Umphezulu wokuvala wonakele; ukungcola kubambekile. Ngokulungisa umphezulu wokuvala nokucoca ukungcola, ukuhamba kwamanzi kwakhona kunokuthintelwa.
