Ivalve yesango ibhekisa kwivalve apho ilungu elivalayo (isango) lihamba kwicala elithe nkqo kumbindi wepaseji.Ivalve yesango ingasetyenziselwa kuphela ukuvalwa ngokupheleleyo kunye nokuvalwa ngokupheleleyo kumbhobho, kwaye ayinakusetyenziselwa uhlengahlengiso kunye ne-throttling.Ivalve yesango luhlobo lwevalve enoluhlu olubanzi losetyenziso.Ngokuqhelekileyo, izixhobo ezinqamlekileyo ze-DN50 zikhethiweyo ukuba zisetyenziswe, kwaye ngamanye amaxesha iivalve zesango nazo zisetyenziselwa izixhobo ezinqamlekileyo ezinobubanzi obuncinci.I-valve yesango isetyenziswe njengendlela yokusika, kwaye yonke into ihamba ngokuthe tye xa ivuliwe ngokupheleleyo.Ngeli xesha, ukulahlekelwa kwengcinezelo yephakathi kuncinci.Iivalve zesango zihlala zifanelekile kwiimeko zokusebenza ezingafuneki ukuba zivulwe kwaye zivaliwe rhoqo kwaye zigcine isango livuleke ngokupheleleyo okanye livalwe ngokupheleleyo.Ayifanelekanga ukusetyenziswa njengommiselo okanye i-throttling.Kwi-high-speed medium flowing, isango linokubangela ukungcangcazela kwesango xa livulwe ngokuyinxenye, kwaye ukungcangcazela kunokonakalisa indawo yokutywina yesango kunye nesihlalo sevalve, kwaye i-throttling iya kubangela ukuba isango lihlanjululwe. phakathi.
Ukususela kwifom yesakhiwo, umahluko oyintloko yindlela yokutywina esetyenzisiweyo.Ngokohlobo lwezinto zokutywina, iivalvu zesango zihlala zohlulwa zibe ziindidi ezininzi ezahlukeneyo, ezinje: ivalve yesango elidityanisiweyo, ivalve yesango elinxuseneyo, ivalve yesango elidityanisiweyo, ivalve yesango elidityanisiweyo, njl njl. kunye neevalvu zesango ezinxuseneyo.
Isango linemigangatho emibini yokutywina.Imiphezulu emibini yokutywina yevalve yesango lewedge edla ngokusetyenziswa yenza i wedge.I-angle ye-wedge iyahluka kunye neeparamitha zevalve, ngokuqhelekileyo i-5 degrees.Isango levalve yesango le-wedge linokwenziwa liphelele, elibizwa ngokuba lisango eliqinileyo;ingenziwa kwakhona kwisango elinokuvelisa i-deformation encinci yokuphucula ukwenziwa kwayo kwaye yenze ukuphambuka kwe-angle yokutywinwa komhlaba ngexesha lokucubungula.Ipleyiti ibizwa ngokuba yisango elastiki.
Xa ivalve yesango ivaliwe, umphezulu wokutywina unokuxhomekeka kuphela kuxinzelelo oluphakathi ukutywina, oko kukuthi, ukuxhomekeka kuxinzelelo oluphakathi ukucinezela indawo yokutywina yesango ukuya kwisihlalo sevalve kwelinye icala ukuqinisekisa ukutywinwa kwe-valve. umphezulu wokutywina, onokuzitywina.Uninzi lweevalvu zesango zisebenzisa ukutywinwa okunyanzeliswayo, oko kukuthi, xa ivalve ivaliwe, isango kufuneka linyanzelwe ngokuchasene nesihlalo ngamandla angaphandle ukuze kuqinisekiswe ukuqina kwendawo yokutywina.
Ivalve yesango yevalve yesango ihamba ngokulandelelana kunye nesikhondo sevalve, ebizwa ngokuba yivalve yesango yesikhondo sokunyusela (ekwabizwa ngokuba yivalve yesango yesikhondo esinyukayo).Ngokuqhelekileyo kukho intambo ye-trapezoidal kwintonga yokuphakamisa, ngokusebenzisa i-nut phezulu kwevalve kunye ne-groove yesikhokelo kumzimba wevalve, intshukumo ejikelezayo iguqulwa ibe yintshukumo yomgca, oko kukuthi, i-torque yokusebenza iguqulwa ibe yinto yokusebenza.
Xa i-valve ivuliwe, xa ukuphakama kwesango kufana ne-1: 1 amaxesha ububanzi be-valve, i-fluid passage ayivaliwe ngokupheleleyo, kodwa esi sikhundla asikwazi ukubeka iliso ngexesha lokusebenza.Ekusetyenzisweni kwangempela, i-apex ye-valve stem isetyenziswe njengophawu, oko kukuthi, indawo apho ayikwazi ukuvulwa, njengendawo yayo evulekile ngokupheleleyo.Ukuze uthathele ingqalelo into yokuvala ngenxa yokutshintsha kweqondo lokushisa, ngokuqhelekileyo ivulwa kwindawo ephezulu, kwaye emva koko i-1/2 ~ 1 ijika, njengendawo yevalve evuleke ngokupheleleyo.Ngoko ke, indawo evulekile ngokupheleleyo ye-valve inqunywe yindawo yesango (oko kukuthi, ukubetha).
I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
