Iflethiivalvu yesangolilungu losapho olukhulu lweevalvu zesango. Njengevalvu yesango le-wedge, umsebenzi wayo ophambili kukulawula ukuvulwa nokuphuma kombhobho, kungekhona ukulungisa ukuhamba kombhobho kumbhobho. Iingenelo zayo kukumelana nolwelo oluphantsi, ukonga abasebenzi ekuvuleni nasekuvaleni, ubude besakhiwo obufutshane, kwaye akukho mda kwicala lokuhamba kombhobho. Ingxaki kukuba isibini sokutywina sineendawo ezimbini zokutywina, ezintsonkothileyo ukuzicwangcisa kwaye zibiza kakhulu. Xa kuthelekiswa nezinye iivalvu, zinde kwaye zinexesha elide lokuvula nokuvala. Ukungqubana phakathi kweendawo zokutywina ngexesha lokuvula nokuvala kunokubangela imikrwelo ngokulula.
2. Iimpawu zesakhiwo semveliso
1. Isihlalo sevalvu sisebenzisa itywina yeringi yokutywina kunye nesakhiwo sesihlalo esidadayo esisebenzisa amandla okuqinisa kwangaphambili ukwenza i-valve inlet kunye ne-outlet zivaleke ngeendlela ezimbini, kwaye i-torque yokuvula nokuvala kwesi sakhiwo yileyo yeevalvu eziqhelekileyo, ezinokuvula nokuvala ivalvu ngokulula.
2. Isihlalo sevalvu sisebenzisa intsimbi engagqwaliyo (okanye i-cobalt-chromium-tungsten alloy) egqunywe okanye ebekwe phezu komphezulu wokutywina, onophawu oluphindwe kabini lwesinyithi kunye nentsimbi ukuya kwisinyithi, kwaye umphezulu wokutywina unokususa ukungcola kwesango ngaxeshanye.
3. Kwiivalvu ezitywiniweyo zentsimbi ukuya kwisinyithi, kukho isakhiwo sokujova igrisi ngaphandle komzimba wevalvu. Igrisi ingena kumphezulu wokutywina ivalvu nge-injector yegrisi kunye nesihlalo sevalvu, ukuze ivalvu ifikelele ekungavuzini nanye.
4. Isango levalvu elinomngxuma wokujika, nokuba livuliwe ngokupheleleyo okanye livaliwe ngokupheleleyo, lihlala lihambelana nomphezulu wokutywina, kwaye umphezulu wokutywina ukhuselwe ekukhukulisekeni ngokuthe ngqo yi-medium, ngaloo ndlela yandisa ubomi benkonzo.
5. Xa ivalvu ivuliwe ngokupheleleyo, indlela ihamba kakuhle kwaye ithe tye, i-coefficient yokumelana nokuhamba kwamanzi incinci kakhulu, kwaye akukho lahleko yoxinzelelo. Umbhobho ungacocwa ngebhola yeenwele.
6. Le valve isebenzisa isakhiwo sokupakisha esinokukwazi ukuzivala, akukho mfuneko yohlengahlengiso rhoqo, ukuvula nokuvala kulula kakhulu, kwaye ukusebenza kokuvala kuthembekile, ibhokisi yokuzalisa ixhotyiswe ngesakhiwo sokufaka igrisi yokuvala encedisayo, ukusebenza kokuvala kuthembekile ngokupheleleyo, kwaye ngokwenene akuphumeleli ukuvuza. Eyona nto inokwenzeka ekuphuzeni ukupakisha ivalvu ngokubanzi iyasuswa.
7. Xa ivalvu ivaliwe, uxinzelelo oluphezulu olukwindawo engaphakathi lunokususwa ngokuzenzekelayo ukuqinisekisa ukusetyenziswa ngokukhuselekileyo.
8. Isakhiwo esivalekileyo ngokupheleleyo, ukusebenza kakuhle kokhuseleko, sinokuziqhelanisa neemfuno zemozulu yonke.
9. Ivalvu ixhotyiswe ngentonga yokubonisa okanye ifestile yokujonga ukubonisa ukuvulwa nokuvalwa kwevalvu.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
