Ivalvu yesango elisicaba yivalvu etyibilikayo enelungu lokuvala elifana nesango elilinganayo. Inxalenye yokuvala ingaba yisango elinye okanye isango eliphindwe kabini elinendlela yokusasaza phakathi.
Amandla okucinezela esango ukuya kwisihlalo sevalvu alawulwa luxinzelelo oluphakathi olusebenza kwisango elidadayo okanye kwisihlalo sevalvu esidadayo. Ukuba yivalvu yesango elisicaba lesango eliphindwe kabini, indlela yokwandisa la masango mabini inokongeza la mandla okucinezela.
1. Iimpawu zevalvu yesango elisicaba
1. Isihlalo sevalvu sisebenzisa uphawu lwe-O-ring kunye nesakhiwo sesihlalo esidadayo esisebenzisa amandla okuqinisa kwangaphambili ukuvala indawo yokungena kunye neyokuphuma yevalvu yesango elithe tyaba kumacala omabini; kwaye i-torque yokuvula nokuvala kwesi sakhiwo yi-1/2 kuphela ye-valvu eziqhelekileyo, ezinokwenza kube lula ukuvula nokuvala. Vala ivalvu;
2. Xa ivuliwe ngokupheleleyo, umjelo uthambile kwaye uthe tye, i-coefficient yokumelana nokuhamba kwamanzi incinci kakhulu, kwaye akukho lahleko yoxinzelelo, kwaye umbhobho ungacocwa ngebhola yeenwele;
3. Isakhiwo sokupakisha esinokukwazi ukuzitywina siyasetyenziswa, ngaphandle kokulungiswa rhoqo, ukuvulwa nokuvalwa kukhaphukhaphu kakhulu, kwaye ukusebenza kokutywina kuthembekile. Kukho isakhiwo sokufaka igrisi yokuvala esincedisayo kwibhokisi yokuzalisa, kwaye ukusebenza kokutywina kuthembekile ngokupheleleyo, kwaye ngokwenene akuphumeleli ukuvuza; isombulula injongo iyona inokwenzeka kakhulu ekuvuzeni xa kupakishwa ivalvu;
4. Xa ivalvu yesango elithe tyaba ivaliwe, uxinzelelo oluphezulu olukwindawo engaphakathi lungasuswa ngokuzenzekelayo ukuqinisekisa ukusetyenziswa ngokukhuselekileyo;
5. Isakhiwo esivalekileyo ngokupheleleyo, ukusebenza kakuhle kokhuseleko, sinokuziqhelanisa neemfuno zemozulu yonke.
2. Izihlandlo ezifanelekileyo zevalvu yesango elisicaba
1. (Iklasi 150~900/PN1.0~16.0MPa, ubushushu bokusebenza -29~121℃) umbhobho wokuhambisa ioyile kunye negesi yendalo. Ivalvu yesango elithe tyaba enomngxuma wokujika ikwalula ukuyicoca umbhobho.
2. Umbhobho wokuthutha kunye nezixhobo zokugcina ioyile ecociweyo.
3. Izixhobo zokukhupha ioyile kunye negesi yendalo, oko kukuthi, iivalvu zemithi yeKrismesi.
4. Imibhobho ene-medium eneziqwenga ezixhonyiweyo.
5. Umbhobho wokuhambisa igesi yesixeko.
6. Amanzi empompi ayasebenza.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
