Injongo yokusebenzisa iivalvu zokukhangela kukuthintela ukuhamba kwesixhobo, ngokubanzi ekuthunyelweni kwepompo ukuze kufakwe iivalvu zokukhangela. Ukongeza, iivalvu zokukhangela kufuneka zifakwe kwindawo yokuphuma kwecompressor. Ngokubanzi, iivalvu zokukhangela kufuneka zifakwe kwizixhobo, iiyunithi okanye imigca ukuthintela i-media reflux.
Iivalvu zokujonga ukuphakama okuthe nkqo zihlala zisetyenziswa kububanzi obuqhelekileyo bombhobho othe tyaba oyi-50mm. Iivalvu zokujonga ukuphakama ezithe tye zinokufakwa kwimigca ethe tye nethe nkqo. Ivalvu esezantsi idla ngokufakwa kuphela kumbhobho othe nkqo wokungena kwepompo, kwaye i-medium iphuma ezantsi iye phezulu.
Ivalvu yokujonga i-swing ingenziwa ibe noxinzelelo oluphezulu lokusebenza, i-PN ukuya kuthi ga kwi-42MPa, kwaye i-DN nayo ingaba nkulu kakhulu, ukuya kuthi ga kwi-2000mm. Ngokwezinto ezikwiqokobhe kunye nesitywino, ingafakwa kuyo nayiphi na indawo yokusebenza kunye nayo nayiphi na indawo yobushushu bokusebenza. Iphakathi ngamanzi, umphunga, igesi, indawo ebolayo, ioyile, ukutya, amayeza njalo njalo. Iqondo lobushushu lokusebenza lendawo yokusebenza liphakathi kwe--196 ℃ kunye ne-800℃.
Iivalvu zokujonga i-swing zihlala zifakelwa kwimigca ethe tye, kodwa zinokufakelwa kwimigca ethe nkqo okanye ethe tye.
Ivalvu yokujonga ibhabhathane ifanelekile kuxinzelelo oluphantsi kunye nobubanzi obukhulu, kwaye amaxesha okufakela anqongophele. Ngenxa yokuba uxinzelelo olusebenzayo lwevalvu yokujonga ibhabhathane alunakuba phezulu kakhulu, kodwa ububanzi obuqhelekileyo bunokuba bukhulu kakhulu, bunokufikelela ngaphezulu kwe-2000mm, kodwa uxinzelelo oluqhelekileyo lungaphantsi kwe-6.4mpa. Iivalvu zokujonga ibhabhathane zinokwenziwa zibe luhlobo lwe-wafer, ngokubanzi zifakwe phakathi kweeflanges ezimbini zombhobho, kusetyenziswa uhlobo loqhagamshelo lwe-clamp.
Iivalvu zokujonga ibhabhathane zingafakwa kumgca othe tye, othe nkqo okanye othe tye.
Ivalvu yokujonga i-diaphragm ifanelekile kwipayipi yokubetha amanzi elula ukuyenza, i-diaphragm inokuba luncedo kakhulu ekupheliseni i-medium countercurrent water strike. Ngenxa yokuba ubushushu bokusebenza kunye noxinzelelo lokusetyenziswa kwevalvu yokujonga i-diaphragm zinqunyelwe zizinto ze-diaphragm, isetyenziswa ngokubanzi kwipayipi yobushushu obuqhelekileyo obuphantsi, ngakumbi efanelekileyo kwipayipi yamanzi. Ubushushu obuphakathi obuqhelekileyo buphakathi kwe -20 ~ 120℃, uxinzelelo olusebenzayo < 1.6mpa, kodwa ivalvu yokujonga i-diaphragm inokwenza ububanzi obukhulu, i-DN ifikelele kwi-2000mm ngaphezulu.
Ivalvu yokujonga i-diaphragm ngenxa yokusebenza kwayo okugqwesileyo kokungena kwamanzi, isakhiwo sayo esilula, iindleko zokuvelisa eziphantsi, ngoko ke kwiminyaka yakutshanje, kusetyenziswe ezinye izicelo.
Ngenxa yokuba isitywino yibhola egqunywe ngerabha, ivalvu yokujonga ibhola isebenza kakuhle ekutywineni, isebenza ngokuthembekileyo kwaye iyakwazi ukumelana nokuchasana namanzi. Kwaye ngenxa yokuba isitywino sinokuba yibhola enye, kwaye singenziwa sibe ziibhola ezininzi, ngoko ke singenziwa sibe yi-caliber enkulu. Kodwa isitywino saso sigqunywe yirabha engenanto, asifanelekanga kwiipayipi ezinoxinzelelo oluphezulu, sifanelekile kuphela kwiipayipi ezinoxinzelelo oluphakathi noluphantsi.
Ngenxa yokuba izinto zeqokobhe levalvu yokujonga engqukuva zinokwenziwa ngentsimbi engagqwaliyo, kwaye i-sphere engenanto yesitywini inokugqunywa ngeplastiki yobunjineli be-polytetrafluoroethylene, ingasetyenziswa nakwindlela yokuhambisa izinto ezirhabaxa.
Olu hlobo lobushushu bokusebenza kwevalvu yokujonga luphakathi kwe-101 ℃ ukuya kwi-150 ℃, uxinzelelo lwayo oluqhelekileyo ≤4.0MPa, ububanzi obuqhelekileyo buphakathi kwe-200 ~ 1200mm.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
